[0010] Embodiments of the present invention will be described below with reference to the drawings. Note that the embodiments described below are examples, and the embodiments to which the present invention is applied are not limited to those described below.

Such existing technologies include, but are not limited to, existing NR or LTE. Furthermore, the term "LTE" as used herein has a broad meaning that includes LTE-Advanced and LTE-Advanced and later technologies (e.g., NR), unless otherwise specified.

This is for convenience of description, and signals, functions, etc. similar to these may be called by other names. Also, the above-mentioned terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even for signals used in NR, it is not always necessary to clearly indicate "NR-".

[0013] In addition, in the embodiments of the present invention, the duplex method may be the TDD (Time Division Duplex) method, the FDD (Frequency Division Duplex) method, or another method (for example, Flexible Duplex, etc.).

[0014] In addition, in the embodiments of the present invention, that a radio parameter or the like is "configured" may mean that a predetermined value is pre-configured, or that a radio parameter notified from a base station or a terminal is configured.

[0015] (System configuration) FIG. 1 is a diagram for explaining a wireless communication system according to an embodiment of the present invention. A wireless communication system according to an embodiment of the present invention includes a base station 10 and a terminal 20, as shown in Figure 1. Although Figure 1 shows one base station 10 and one terminal 20, this is an example, and there may be multiple base stations 10 and terminal 20.

[0016] Base station 10 is a communication device that provides one or more cells and performs wireless communication with terminal 20. The physical resources of the wireless signal are defined in the time domain and the frequency domain. The time domain may be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols, and the frequency domain may be defined by the number of subcarriers or resource blocks. In addition, the TTI (Transmission Time Interval) in the time domain may be a slot, or the TTI may be a subframe.

[0017] The base station 10 transmits synchronization signals and system information to the terminal 20. The synchronization signals are, for example, NR-PSS and NR-SSS. The system information is transmitted, for example, via NR-PBCH and is also called broadcast information. The synchronization signals and system information may also be called SSB (SS / PBCH block). As shown in Figure 1, the base station 10 transmits control signals or data to the terminal 20 via DL (Downlink) and receives control signals or data from the terminal 20 via UL (Uplink). Both the base station 10 and the terminal 20 are capable of transmitting and receiving signals using beamforming. Furthermore, both the base station 10 and the terminal 20 are capable of applying MIMO (Multiple Input Multiple Output) communication to DL or UL. In addition, both the base station 10 and the terminal 20 may communicate via secondary cells (SCell) and primary cells (PCell) using CA (Carrier Aggregation). Furthermore, terminal 20 may communicate via the primary cell of base station 10 and the primary secondary cell group cell (PSCell: Primary SCG Cell) of other base stations 10 using DC (Dual Connectivity).

[0018] Terminal 20 is a communication device equipped with wireless communication capabilities, such as a smartphone, mobile phone, tablet, wearable device, or M2M (Machine-to-Machine) communication module. As shown in Figure 1, Terminal 20 receives control signals or data from the base station 10 via DL and transmits control signals or data to the base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. Terminal 20 also receives various reference signals transmitted from the base station 10 and performs propagation path quality measurements based on the reception results of these reference signals. Terminal 20 may also be referred to as UE and base station 10 as gNB.

[0019] (Basic operation) Figure 2 shows an example of a basic procedure in an embodiment of the present invention. First, an example of basic operation in the wireless communication system of this embodiment will be described with reference to Figure 2.

[0020] In S100, terminal 20 transmits capability information (UE capability) to base station 10. Based on this capability information, base station 10 can determine, for example, the content of the information to be transmitted to terminal 20 in S101 and S102 below.

[0021] In S101, the base station 10 sends configuration information to the terminal 20 via an RRC message, and the terminal 20 receives the configuration information. This configuration information includes, for example, the K1 set and the TDRA table, as described later. The K1 set and the TDRA table may be notified to the terminal 20 from the base station 10, or they may be predetermined by specifications, etc., and the base station 10 and the terminal 20 may use those predetermined ones. The TDRA table may also be called time domain resource allocation configuration information.

[0022] In S102, base station 10 transmits scheduling (allocation information) for one or more PDSCHs to terminal 20 via DCI, and terminal 20 receives the DCI. The DCI also includes information about uplink resources for transmitting HARQ-ACK information.

[0023] In S103, terminal 20 receives a PDSCH based on scheduling information in DCI, and in S104 transmits HARQ-ACK information to base station 10. Base station 10 receives the HARQ-ACK information. Note that the PDSCH may be a PDSCH received without a corresponding DCI, for example, a PDSCH received in a periodic PDSCH reception function called semi-persistent scheduling (SPS).

[0024] Traditionally, two scheduling methods have been defined for uplinks: Dynamic grant and Configured grant. Dynamic grant is a procedure in which scheduling is performed in response to scheduling requests from terminals. Configured grant is a procedure in which scheduling is performed without scheduling requests from terminals in order to reduce uplink latency.

[0025] Figure 3 is a sequence diagram showing an example of the processing flow for Dynamic Grant. When Dynamic Grant is configured by RRC, terminal 20 sends a schedule request to base station 10 when uplink data is generated (step S11). In response to the received schedule request, base station 10 sends a signal to terminal 20 indicating uplink permission (step S12).

[0026] When the uplink is permitted, terminal 20 sends a BSR (Buffer Status Report) and / or uplink data to base station 10 (step S13).

[0027] Figure 4 is a sequence diagram showing an example of the CG processing flow. If the CG is configured by RRC and / or activated by DCI, PUSCH resources are allocated to terminal 20 individually in advance. When uplink data is generated, terminal 20 transmits the BSR and / or uplink data to base station 10 without making a schedule request (step S21).

[0028] (Previous problems) Conventionally, terminal 20 transmits UCI as a physical layer signal to base station 10 using PUCCH or PUSCH. Here, we will describe the procedure for handling cases where PUCCH and PUSCH, which include UCI, collide within the same slot.

[0029] For example, if two or more PUCCHs collide in the time domain, the UCIs contained in those PUCCHs are multiplexed or at least partially dropped, and the UCIs to be transmitted are sent to the base station 10 via one or another of those PUCCHs.

[0030] For example, if PUCCH and PUSCH collide in the time domain, the UCI and / or data (UL-SCH) contained therein are multiplexed, or at least a portion of it is dropped, and the UCI and / or data to be transmitted is sent to base station 10 via the PUCCH or PUSCH.

[0031] Figure 5 is a diagram illustrating the control procedure related to the collision of PUCCH and PUSCH. Terminal 20 allows the collision and assigns PUCCH and PUSCH to slot n, as shown in Figure 5(a).

[0032] Next, terminal 20 assigns numbers to PUCCH in the following order of priority, as shown in Figure 5(b). 1. The first symbol is faster. 2. Longer period

[0033] Note that the numbering method when the initial symbol and period are the same depends on the implementation of terminal 20. Then, as shown in Figure 5(c), terminal 20 duplicates or drops the UCI in the first overlap set. Subsequently, as shown in Figure 5(d), terminal 20 renumbers the PUCCH.

[0034] Next, terminal 20 multiplexes or drops UCIs in the second overlap set, as shown in Figure 5(e). Here, the set includes PUCCHs that conflict with the highest-priority PUCCH in the set.

[0035] Then, as shown in Figure 5(f), terminal 20 transmits the UCI by multiplexing it with the PUSCH that is about to collide, once there are no more collisions between PUCCHs.

[0036] Thus, since the conventional terminal 20 transmits the UCI to the base station 10 as a physical layer signal via PUCCH or PUSCH, if a technology is adopted that allows for the free allocation of PUCCH or PUSCH within a slot, there will be countless patterns of PUCCH and / or PUSCH collisions, making the control related to PUCCH and PUSCH collisions, including the UCI, extremely complex.

[0037] Furthermore, provisions regarding securing control time for terminal 20 will also be necessary. Moreover, the situation could become even more complex when various neurology methods and priorities for distinguishing between eMBB / URLLC are involved.

[0038] Furthermore, the UCI may include, but is not limited to, the following information A)-C), and may also include any control information transmitted from terminal 20 to base station 10. A) HARQ-ACK: Detection success / failure report for receiving downlink data or control information (e.g., receiving SPS release notification, receiving SCell dormancy notification). B) SR: Request signal to base station 10 for uplink data transmission and control information transmission (for example, transmission of information related to beam failure recovery in SCell). C) CSI: Information reporting related to the channel status of the downlink (e.g., Channel quality indicator, Rank indicator, Precoding matrix indicator, Layer 1 reference signal received power).

[0039] (Summary of this embodiment) To solve the conventional problems described above, this embodiment describes a method for more easily implementing control related to UCI transmission. This makes it possible to reduce the cost and power consumption of terminals.

[0040] Examples 1 to 3 will be described below as specific examples.

[0041] (Example 1) Example 1 describes an example in which terminal 20 transmits UCI via PUSCH at a lower or upper layer. Here, an upper layer is a layer located above the physical layer, and includes, for example, the MAC layer, PDCP layer, RLC layer, etc. A lower layer is a layer located below the upper layer, and refers to the physical layer.

[0042] In other words, the terminal 20 of this embodiment differs from conventional devices in that it always transmits UCI via PUSCH without going through PUCCH, and transmits UCI via a higher layer.

[0043] <Option 1-1> Terminal 20 may send a HARQ-ACK at a lower or upper layer via PUSCH.

[0044] Terminal 20 may determine a PUSCH for HARQ-ACK transmission corresponding to a scheduled PDSCH based on PUSCH allocation information included in the downlink scheduling signal (DCI) transmitted from base station 10.

[0045] Here, the cell to which terminal 20 transmits PUSCH may be limited to a predetermined cell (e.g., a SpCell, a cell where HARQ feedback is permitted, etc.), or it may be possible to transmit to any cell.

[0046] The cell that transmits PUSCH may be set or specified by base station 10. Furthermore, PUSCH may be specified in one of the following ways:

[0047] In the first method, base station 10 specifies time or frequency resources in separate fields. This is a specification method similar to the PUSCH scheduling defined in NR.

[0048] In the second method, the base station 10 pre-configures multiple PUSCH resources and specifies which of the configured PUSCH resources to use each time. This is a specification method similar to the PUSCH instruction defined in NR.

[0049] The first method is more flexible than the second method. Conversely, the second method is simpler to specify and requires less information than the first method.

[0050] Terminal 20 may receive notification from base station 10 via the PUSCH indicating whether or not it is possible to transmit signals other than HARQ-ACK (such as data (MAC-PDU) or MAC-CE containing other information). In this embodiment, MAC-PDU may be replaced with MAC SDU.

[0051] Figure 6 is a diagram illustrating the method for transmitting HARQ-ACK according to option 1-1 of Example 1. As shown in Figure 6, terminal 20 may generate HARQ-ACK based on the decoding result of PDSCH and transmit it as a higher layer signal. The higher layer signal may be, for example, MAC-CE.

[0052] Furthermore, the base station 10 may instruct the terminal 20 via each DCI to provide information related to HARQ-ACK multiplexing (HARQ-ACK codebook generation). For example, the base station 10 may instruct which PUSCH resource to multiplex or which multiplexing group to multiplex. The method for instructing which multiplexing group to multiplex will be described later in Example 2.

[0053] Furthermore, terminal 20 may also send HARQ-ACK transmissions instructed for the same time unit (e.g., slot) via the same PUSCH.

[0054] Furthermore, terminal 20 may transmit a HARQ-ACK via the PUSCH resource indicated by the last DCI in terms of time or frequency among the multiplexed HARQ-ACKs.

[0055] According to Option 1-1, multiplexing due to overlapping of physical channels used for HARQ-ACK becomes unnecessary, and the processing at the physical layer can be made equivalent to the PUSCH transmission related to data transmission. This simplifies the configuration of terminal 20.

[0056] <Option 1-2> Terminal 20 may send a scheduling request (SR) at a lower or upper layer via PUSCH.

[0057] Figure 7 is a diagram illustrating the method of transmitting an SR according to option 1-2 of Embodiment 1. Terminal 20 may have a configured grant PUSCH set by base station 10 as a resource for transmitting an SR. That is, base station 10 may set up a periodically scheduled PUSCH resource.

[0058] Terminal 20 may transmit signals other than the SR (data (MAC-PDU), MAC-CE containing other information, BSR, etc.) in addition to or instead of the SR.

[0059] Terminal 20 does not need to anticipate that, after sending an SR, it will be instructed via DCI to retransmit the PUSCH transmission related to the SR. In other words, a HARQ processing number does not need to be assigned for PUSCH transmissions that include an SR.

[0060] Terminal 20 may be able to transmit SRs when configured by base station 10 using RRC or the like, or it may be able to transmit SRs when instructed by base station 10, for example, by activation DCI, MAC-CE, or the like.

[0061] Terminal 20 may have a Modulation Coding Scheme (MCS) for SR transmission set by base station 10, determine the MCS using a predetermined method, or notify base station 10 of the MCS using a predetermined method (e.g., a sequence of Reference Signals (RS)).

[0062] Furthermore, terminal 20 may have a configured grant PUSCH set by base station 10 as a resource for BSR transmission. In other words, there may be no resources for SR transmission, and the SR itself may not be defined, and the operation may start with BSR transmission when requesting a PUSCH resource.

[0063] Terminal 20 may transmit signals other than the BSR (data (MAC-PDU), MAC-CE containing other information, etc.) in addition to or instead of the BSR.

[0064] Terminal 20 may be able to transmit BSR by being configured by base station 10 via RRC or the like, or it may be able to transmit BSR by being instructed by base station 10, for example, via activation DCI, MAC-CE, or the like.

[0065] Terminal 20 may have a Modulation Coding Scheme (MCS) for BSR transmission set by base station 10, determine the MCS using a predetermined method, or notify base station 10 of the MCS using a predetermined method (e.g., a sequence of RS (Reference Signals)).

[0066] According to option 1-2, multiplexing due to overlapping of physical channels used for SR or BSR becomes unnecessary, and the processing at the physical layer can be made equivalent to the PUSCH transmission related to data transmission. This simplifies the configuration of terminal 20.

[0067] <Options 1-3> Terminal 20 may transmit CSI (Channel Status Information) at a lower or upper layer via PUSCH.

[0068] Figure 8 is a diagram illustrating the CSI transmission method according to option 1-3 of Embodiment 1. Terminal 20 may have a configured grant PUSCH set by base station 10 as a resource for CSI transmission. That is, base station 10 may set a periodically scheduled PUSCH resource.

[0069] Terminal 20 may transmit signals other than CSI (data (MAC-PDU), MAC-CE or BSR containing other information) in addition to or instead of CSI.

[0070] Terminal 20 does not need to anticipate that, after sending a CSI, it will be instructed to retransmit a PUSCH transmission related to that CSI via DCI. In other words, a HARQ processing number does not need to be assigned for a PUSCH transmission that includes a CSI.

[0071] Terminal 20 may be capable of CSI transmission when configured by base station 10 via RRC or the like, or it may be capable of CSI transmission when instructed by base station 10, for example, via activation DCI, MAC-CE, or the like.

[0072] Terminal 20 may have a Modulation Coding Scheme (MCS) for CSI transmission set by the base station 10, determine the MCS using a predetermined method, or notify the base station 10 of the MCS using a predetermined method (for example, a sequence of Reference Signals (RS)).

[0073] Furthermore, terminal 20 may transmit CSI as a higher-layer signal (e.g., MAC-CE).

[0074] Furthermore, terminal 20 may transmit aperiodic CSI reports to base station 10 based on instructions from base station 10 via higher layer (MAC-CE, etc.) or lower layer (DCI, etc.).

[0075] According to option 1-3, multiplexing due to overlapping of physical channels used for CSI becomes unnecessary, and the processing at the physical layer can be made equivalent to the PUSCH transmission related to data transmission. This simplifies the configuration of terminal 20.

[0076] <Options 1-4> Terminal 20 may transmit various UCIs (HARQ-ACK, SR, CSI, etc.) at lower or upper layers via PUSCH.

[0077] Figure 9 is a diagram illustrating the UCI transmission method according to options 1-4 of Example 1. Terminal 20 may have a configured grant PUSCH set by base station 10 as a resource usable for any UCI transmission. That is, base station 10 may set a periodically scheduled PUSCH resource as a resource usable for any UCI transmission (and therefore as a resource whose use is not specified / limited to one type of UCI transmission).

[0078] Terminal 20 may transmit any HARQ-ACK, SR, and CSI signals via any configured resource. In other words, terminal 20 performs a PUSCH transmission of a Configured grant without channel collisions.

[0079] Terminal 20 is instructed by base station 10 to specify a time (e.g., slot) and at least one of the cells for sending a HARQ-ACK corresponding to a scheduled PDSCH. Terminal 20 may then use a configured grant PUSCH transmission at at least one of the instructed time and cell for the HARQ-ACK transmission.

[0080] In other words, the base station 10 does not need to give explicit instructions via DCI to define more detailed resources for PUSCH (e.g., symbols, PRBs (Physical Resource Blocks), etc.).

[0081] Terminal 20 may use the configured grant's PUSCH for SR transmission if uplink data is generated and the configured grant's PUSCH transmission is insufficient for data transmission.

[0082] Terminal 20 may periodically measure and acquire the CSI, and if the difference between the previously transmitted CSI and the acquired CSI exceeds a predetermined threshold, it may transmit the CSI to base station 10. In other words, terminal 20 does not have to transmit the CSI if the difference does not exceed a predetermined threshold.

[0083] Alternatively, terminal 20 may periodically measure and acquire CSI, and transmit CSI to base station 10 when the time elapsed since the last CSI transmission exceeds a predetermined threshold. In other words, terminal 20 does not need to transmit CSI if the elapsed time does not exceed a predetermined threshold.

[0084] Alternatively, terminal 20 may transmit a CSI based on the PDSCH decoding result. That is, terminal 20 may transmit a CSI when radio wave reception conditions are not good.

[0085] When multiple UCI transmissions occur, terminal 20 may transmit all UCIs if it has sufficient resources to transmit all the information, or it may select and transmit some UCIs if it does not have enough resources.

[0086] In that case, terminal 20 may have a predetermined priority order for selecting UCI. For example, the priority order could be HARQ-ACK > SR > CSI, or SR > HARQ-ACK > CSI.

[0087] Terminal 20 may transmit the UCI that was not transmitted via another PUSCH (let's call it PUSCH Y). In that case, terminal 20 may transmit information indicating that the UCI that was not transmitted is transmitted via PUSCH Y and / or information relating to its resources via the PUSCH (let's call it PUSCH X) containing the selected UCI. Alternatively, terminal 20 may transmit information indicating that the UCI was not transmitted via PUSCH X and / or information relating to the resources of PUSCH X via PUSCH Y containing the UCI that was not transmitted.

[0088] Terminal 20 may transmit signals other than UCI (data (MAC-PDU), MAC-CE or BSR containing other information) in addition to or instead of UCI.

[0089] Terminal 20 does not need to anticipate that, after sending a UCI, it will be instructed to retransmit a PUSCH transmission related to that UCI via DCI. In other words, a HARQ processing number does not need to be assigned for PUSCH transmissions that include a UCI.

[0090] Terminal 20 may have a Modulation Coding Scheme (MCS) for UCI transmission set by base station 10, determine the MCS using a predetermined method, or notify base station 10 of the MCS using a predetermined method (e.g., a sequence of Reference Signals (RS)).

[0091] According to option 1-4, terminal 20 can prepare a common channel for all UCIs and use that channel as its basic operation, thereby avoiding complex operations related to multiplexing.

[0092] (Example 2) In this embodiment, we will describe a method in which the terminal 20 receives instructions from the base station 10 on which multiplexing group to multiplex, and then multiplexes the uplink information.

[0093] Terminal 20 may multiplex at least one of UCI and non-UCI uplink information (data (MAC-PDU), MAC-CE including other information, etc.) based on a multiplexing group instruction. The multiplexing group instruction is an instruction received from base station 10 that indicates which multiplexing group to multiplex into.

[0094] Figure 10 is a diagram illustrating the method for multiplexing uplink information according to Embodiment 2. Terminal 20 multiplexes uplink information scheduled in at least one of a predetermined time unit (e.g., slot) and frequency unit (e.g., cell) into the same PUSCH based on a multiplexing group instruction. That is, terminal 20 may multiplex and transmit PUSCH without causing channel collisions.

[0095] The multiplexing instruction specifically includes group identifiers such as Group 1, Group 2, etc. Terminal 20 then multiplexes information for the same group into the same PUSCH. Here, as shown in Figure 10, terminal 20 may multiplex information for the same group regardless of whether there is overlap or not.

[0096] <Option 2-0: Multiple Groups> Terminal 20 may have a maximum number of groups set by base station 10 for multiple groups. Base station 10 and terminal 20 may also determine the DCI field size based on the settings. Furthermore, in the DCI used for initial access, the number of groups in multiple groups may be a predetermined number (e.g., 1).

[0097] Terminal 20 does not need to assume that PUSCHs related to different multiplex groups will overlap in the time domain within the same cell. In other words, base station 10 issues multiplex group instructions so that PUSCHs related to different multiplex groups do not overlap in the time domain within the same cell.

[0098] <Option 2-1: HARQ-ACK> The base station 10 may instruct the terminal 20 to use multiplex groups based on each DCI that schedules the PDSCH, and the terminal 20 may receive such instructions. The terminal 20 may generate a HARQ-ACK codebook for each multiplex group.

[0099] <Option 2-2: SR> Base station 10 may configure the SR multiplexing group in the higher layer settings, and terminal 20 may receive this setting. Alternatively, the specification may define which multiplexing group the SR belongs to (for example, group 0).

[0100] <Options 2-3: CSI> Base station 10 may configure the CSI multiplexing group in the upper layer settings, and terminal 20 may receive this configuration. Alternatively, the specification may define which multiplexing group the CSI belongs to (for example, group 0). Furthermore, base station 10 may specify the multiplexing group in the DCI requesting the CSI, and terminal 20 may receive this instruction.

[0101] Furthermore, different methods may be used for setting up or specifying multiple groups depending on the CSI reporting type (aperiodic, semi-permanent, periodic, etc.).

[0102] <Options 2-4: UL-SCH> Base station 10 may configure multiplex groups for UL-SCH (uplink shared channel) in the upper layer settings, and terminal 20 may receive such settings. Alternatively, the specification may define which multiplex group UL-SCH belongs to (for example, group 0). Settings and definitions may be made in predetermined units, for example, per HARQ processing number, per priority information, or per PUSCH resource information. Terminal 20 may also receive the multiplex group designation via UL grant.

[0103] Furthermore, different methods may be used for configuring or specifying multiple groups for Dynamic grant PUSCH and Configured grant PUSCH.

[0104] <Options 2-5> If there are multiple DCIs corresponding to the multiplexed information, terminal 20 may transmit the multiplexed information to base station 10 using the PUSCH resource indicated by the last time or frequency DCI.

[0105] <Options 2-6> If there is no DCI corresponding to the multiplexed information, terminal 20 may transmit the multiplexed information to base station 10 using a predetermined PUSCH resource. In this case, terminal 20 may select the PUSCH resource according to a predetermined priority order. The priority order may be, for example, Configured grant PUSCH for UL-SCH > PUSCH for CSI > PUSCH for SR.

[0106] In this embodiment, PUSCH may be replaced with PUCCH. In the case of PUCCH, terminal 20 may also transmit uplink information by multiplexing without causing channel collisions.

[0107] This embodiment may be combined with Embodiment 1.

[0108] In this embodiment, the terminal 20 can avoid complex processing related to multiplexing at the terminal by having the base station 10 give explicit multiplexing instructions.

[0109] (Example 3) This embodiment describes an example in which terminal 20 simultaneously transmits multiple uplink information via the same time resource.

[0110] Terminal 20 may simultaneously transmit "multiple PUCCH" or "PUCCH and PUSCH" via the same time resource.

[0111] <Option 3-1> Terminal 20 may simultaneously transmit "multiple PUCCH" or "PUCCH and PUSCH" within a certain frequency unit (for example, CC or cell, hereafter referred to as cell). That is, terminal 20 transmits simultaneously without multiplexing in the event of a collision in the time domain.

[0112] Terminal 20 may consolidate HARQ-ACKs in each cell (generating a HARQ-ACK codebook for each cell) and may not multiplex them with SR or CSI. In other words, terminal 20 may simultaneously transmit at least one of the following four signals in a given cell: PUCCH for HARQ-ACK, PUCCH for SR, PUCCH for CSI, and PUSCH.

[0113] <Option 3-2> Terminal 20 may simultaneously transmit "multiple PUCCH" messages or "PUCCH and PUSCH" messages across multiple cells.

[0114] Terminal 20 does not need to transmit simultaneously within each cell. Therefore, terminal 20 performs multiple operations within each cell in the event of a collision in the time domain. Alternatively, regardless of whether or not there is a collision in the time domain, multiple operations based on the multiple group of Example 2, for example, may be performed within each cell. Here, "each cell" may be replaced with "a group of cells that have the same neural network".

[0115] Terminal 20 may be capable of PUCCH transmission in all cells. Terminal 20 generates a HARQ-ACK codebook for each cell. PUCCH for SR and CSI transmission may be configured in each cell.

[0116] Base station 10 may schedule a PUCCH in the same cell by the DCI that assigns the PDSCH. Terminal 20 may transmit a HARQ-ACK corresponding to the PDSCH in the cell related to the PUCCH. This operation may be performed in any cell.

[0117] Furthermore, the base station 10 may instruct the cell to schedule the PUCCH by the DCI to which the PDSCH is assigned. The terminal 20 may transmit the HARQ-ACK corresponding to the PDSCH in the cell related to the PUCCH. Here, it may be specified whether to transmit in a predetermined cell (for example, SpCell or PUCCH SCell) or in the same cell.

[0118] <Option 3-3> Terminal 20 may be assumed to be configured or notified by base station 10 whether to perform option 3-1 or option 3-2. Here, the information configured or notified may be explicit or implicit, i.e., information configured or notified indirectly by other information.

[0119] According to this embodiment, the multiple operations of terminal 20 associated with collisions can be minimized, and the configuration of terminal 20 can be simplified.

[0120] Figure 11 is a diagram illustrating the simultaneous transmission of uplink information according to Example 3. According to Option 3-1, even if multiple HARQ-ACKs collide in the time domain, they are transmitted simultaneously within the same cell. According to Option 3-2, if multiple HARQ-ACKs collide in the time domain, they are multiplexed within the same cell, but if they span across cells, they are transmitted simultaneously without multiplexing.

[0121] Terminal 20 may notify base station 10 of capability information indicating whether or not it supports the operation of each embodiment described above. Based on the notified capability information, base station 10 may configure or instruct terminal 20.

[0122] (Device configuration) Next, we will describe an example of the functional configuration of the base station 10 and terminal 20 that perform the processes and operations described above.

[0127] The transmitting unit 210 creates a transmission signal from the transmission data and transmits the transmission signal wirelessly. The receiving unit 220 wirelessly receives various signals and obtains signals from higher layers from the received physical layer signals. The transmitting unit 210 also transmits a HARQ-ACK, and the receiving unit 220 receives the configuration information and the like as described in the embodiment.

[0128] The setting unit 230 stores various setting information received from the base station 10 by the receiving unit 220 in a storage device and reads it from the storage device as needed. The setting unit 230 also stores pre-set setting information. The control unit 240 controls the entire terminal 20, including control related to signal transmission and reception. The signal transmission function in the control unit 240 may be included in the transmission unit 210, and the signal reception function in the control unit 240 may be included in the reception unit 220.

[0166] In addition, terms used in this disclosure and terms necessary for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, at least one of the channel and symbol may be a signal (signaling). Also, a signal may be a message. Furthermore, a component carrier (CC) may be called a carrier frequency, cell, frequency carrier, etc.

[0167] The terms “system” and “network” as used in this disclosure are interchangeable.

[0168] Furthermore, the information, parameters, etc., described in this disclosure may be expressed using absolute values, relative values ​​from a given value, or other corresponding information. For example, wireless resources may be indicated by an index.

[0169] The names used for the parameters described above are not restrictive in any way. Furthermore, the formulas and other expressions using these parameters may differ from those expressly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, and therefore, the various names assigned to these various channels and information elements are not restrictive in any way.

[0170] In this disclosure, terms such as "base station (BS)", "wireless base station", "base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", and "component carrier" may be used interchangeably. Base stations may also be referred to by terms such as macrocell, small cell, femtocell, and picocell.

[0171] A base station can accommodate one or more (e.g., three) cells. If a base station accommodates multiple cells, the entire coverage area of ​​the base station can be divided into several smaller areas, each of which may also be provided with communication services by a base station subsystem (e.g., a Remote Radio Head (RRH)). The terms “cell” or “sector” refer to part or all of the coverage area of ​​at least one of the base station and / or base station subsystems that provide communication services in that coverage.

For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0175] Furthermore, the term "base station" in this disclosure may be interpreted as "user terminal." For example, the various aspects / embodiments of this disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between multiple terminals 20 (which may be called, for example, D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, the terminals 20 may have the functions that the base station 10 has. Also, terms such as "uplink" and "downlink" may be interpreted as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, uplink channel, downlink channel, etc., may be interpreted as side channel.

[0176] Similarly, the term "user terminal" in this disclosure may be replaced with "base station." In this case, the base station may be configured to have the same functions as the user terminal described above.

[0177] As used in this disclosure, the terms “determining” and “determining” may encompass a wide variety of actions. “Determining” may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, inquiry (e.g., searching in a table, database, or other data structure), and ascertaining. “Determining” may also include, for example, receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, and accessing (e.g., accessing data in memory). Furthermore, "judgment" and "decision" can include considering something as having been "judged" or "decided" after resolving, selecting, choosing, establishing, comparing, etc. In other words, "judgment" and "decision" can include considering something as having been "judged" or "decided" after some action. Also, "judgment (decision)" can be reinterpreted as "assuming," "expecting," or "considering."

[0178] The terms “connected,” “coupled,” or any variation thereof, mean any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are “connected” or “coupled” with each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, “connection” may be reinterpreted as “access.” As used in this disclosure, two elements may be considered to be “connected” or “coupled” with each other using at least one of one or more wires, cables, and printed electrical connections, and, in some non-limiting and non-exclusive examples, electromagnetic energy having wavelengths in the radio frequency domain, microwave domain, and optical (both visible and invisible) domain.

[0179] The reference signal can also be abbreviated as RS (Reference Signal), and may be called a pilot depending on the applicable standard.

[0180] In this disclosure, the phrase "based on" does not mean "based solely on" unless otherwise specified. In other words, the phrase "based on" means both "based solely on" and "based at least on."

[0181] Any reference to elements using the designations “first,” “second,” etc., as used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient way to distinguish between two or more elements. Accordingly, references to the first and second elements do not imply that only two elements may be employed, or that the first element must precede the second element in any way.

[0182] In the configuration of each of the above devices, "means" may be replaced with "part," "circuit," "device," etc.

[0183] Where the terms “include,” “including,” and variations thereof are used in this disclosure, these terms are intended to be inclusive, as is the term “comprising.” Furthermore, the term “or” as used in this disclosure is not intended to mean exclusive OR.

[0184] A wireless frame may consist of one or more frames in the time domain. Each of these frames in the time domain may be called a subframe. A subframe may further consist of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0185] Numerical logic may be communication parameters applied to at least one of the transmission and reception of a signal or channel. Numerical logic may include, for example, at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, specific filtering processes performed by the transceiver in the frequency domain, and specific windowing processes performed by the transceiver in the time domain.

[0186] A slot may consist of one or more symbols in the time domain (such as OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A slot may also be a time unit based on neurology.

[0187] A slot may include multiple minislots. Each minislot may consist of one or more symbols in the time domain. Minislots may also be called subslots. Minislots may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (or PUSCH) mapping type B.

[0188] Wireless frames, subframes, slots, minislots, and symbols all represent units of time when transmitting a signal. Different names may be used for each of these terms.

[0189] For example, one subframe may be called a Transmission Time Interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one mini-slot may be called a TTI. In other words, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, mini-slot, etc., instead of a subframe.

[0190] Here, TTI refers to, for example, the smallest unit of time for scheduling in wireless communication. For example, in an LTE system, the base station schedules each terminal 20 to allocate wireless resources (such as the frequency bandwidth and transmission power available to each terminal 20) in TTI units. However, the definition of TTI is not limited to this.

[0191] TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, code words, etc., or it may be a processing unit for scheduling, link adaptation, etc. Given a TTI, the actual time interval (e.g., number of symbols) to which the transport block, code block, code word, etc. are mapped may be shorter than the given TTI.

[0192] Furthermore, if one slot or one mini-slot is referred to as TTI, then one or more TTIs (i.e., one or more slots or one or more mini-slots) may constitute the minimum time unit of scheduling. In addition, the number of slots (number of mini-slots) that constitute the minimum time unit of scheduling may be controlled.

[0193] A TTI with a time length of 1ms may also be called a normal TTI, long TTI, normal subframe, long subframe, slot, etc. A TTI shorter than a normal TTI may also be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, mini slot, sub slot, slot, etc.

[0194] Furthermore, long TTIs (e.g., normal TTIs, subframes, etc.) may be interpreted as TTIs with a time length exceeding 1 ms, and short TTIs (e.g., shortened TTIs, etc.) may be interpreted as TTIs with a TTI length less than that of a long TTI but 1 ms or more.

[0195] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and in the frequency domain, it may contain one or more consecutive subcarriers. The number of subcarriers in an RB may be the same regardless of the neurology, for example, 12. The number of subcarriers in an RB may be determined based on the neurology.

[0196] Furthermore, the time domain of the RB may contain one or more symbols and may be the length of one slot, one minislot, one subframe, or one TTI. Each TTI, subframe, etc., may consist of one or more resource blocks.

[0197] One or more RBs may also be called a Physical RB (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB pair, RB pair, etc.

[0198] Furthermore, a resource block may consist of one or more resource elements (REs). For example, one RE may be a radio resource area comprising one subcarrier and one symbol.

[0199] A Bandwidth Part (BWP), also known as a partial bandwidth, may represent a subset of consecutive common resource blocks (RBs) for a particular neurology system in a given carrier. These common RBs may be identified by an index of the RBs relative to a common reference point of the carrier. A Bandwidth Part (PRB) may be defined and numbered within a given BWP.

[0200] A BWP may include a BWP for UL (Ultraviolet Link) and a BWP for DL ​​(Download Link). One or more BWPs may be set for a terminal 20 within a single carrier.

[0201] At least one of the configured BWPs may be active, and terminal 20 does not need to be expected to send or receive a predetermined signal / channel outside of the active BWP. In this disclosure, terms such as "cell" and "carrier" may be read as "BWP".

[0202] The structures described above, such as wireless frames, subframes, slots, minislots, and symbols, are merely illustrative. For example, the number of subframes included in a wireless frame, the number of slots per subframe or wireless frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, and the number of symbols, symbol length, and cyclic prefix (CP) length within a TTI can be varied in various ways.

[0203] In this disclosure, if articles are added through translation, such as a, an, and the in English, this disclosure may include the fact that the noun following these articles is plural.

[0204] In this disclosure, the term "A and B are different" may mean "A and B are different from each other." The term may also mean "A and B are each different from C." Terms such as "separate" and "combine" may be interpreted similarly to "different."

[0205] Each aspect / embodiment described herein may be used individually, in combination, or switched between as needed during implementation. Furthermore, notification of specific information (e.g., notification that "X is") is not limited to explicit notification, but may also be implicit (e.g., by not providing such notification).

[0206] Although the present disclosure has been described in detail above, it will be clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in modified and altered forms without departing from the intent and scope of the present disclosure as defined by the claims. Therefore, the descriptions in the present disclosure are illustrative and not intended to be restrictive in any way. [Explanation of Symbols]
