[0002] In the Universal Mobile Telecommunication System (UMTS) network, Long Term Evolution (LTE) has been standardized for the purpose of achieving higher data rates and lower latency. Furthermore, research is underway to develop successor systems to LTE, aiming to further expand the bandwidth and increase the speed of LTE. Successor systems to LTE include LTE-Advanced (LTE-A), Future Radio Access (FRA), 5th generation mobile communication system (5G), 5G plus (5G+), Radio Access Technology (New-RAT), and New Radio (NR).

[0004] In NR, the configuration of CG PUSCH (Configured Grant Physical Uplink Shared Channel) is specified in Release 16 (for example, Non-Patent Document 2). CG PUSCH includes Type 1 CG PUSCH and Type 2 CG PUSCH.

[0005] In Release 17, research is underway into extended reality (XR), including virtual reality (VR) and mixed reality (MX). The company is examining XR scenarios, requirements, key performance indicators (KPIs), and evaluation methods. Targeted XR requirements include capacity, latency, mobility, and energy efficiency.

[0024] The following describes an embodiment of one aspect of the present disclosure with reference to the accompanying drawings. In URLLC, research is underway to enhance the functionality of terminal feedback for Hybrid Automatic Repeat Request - Acknowledgement (HARQ-ACK). HARQ-ACK is an example of information related to a terminal's confirmation response (e.g., an acknowledgment) to received data. Among these URLLC research items, an agreement has been reached to support dynamic and semi-static PUCCH carrier switching. Alternatively, PUCCH carrier switching may be referred to by other names, such as carrier switching for sending control information.

[0025] PUCCH carrier switching is a technique used when a base station communicates via multiple cells. Dual connectivity and PUCCH carrier switching are described below as an example of communication via multiple cells.

[0026] <Dual Connection>

[0027] Figure 1 is a diagram showing an example of dual connection (DC). Figure 1 In the example, base station 10-1 can also be a master node (Master Node (MN)). Base station 10-2 can also be a secondary node (Secondary Node (SN)). Figure 1 As shown in the example, in DC, carriers between different base stations are bundled.

[0028] exist Figure 1 In the example of , the base station 10 - 1 communicates with the terminal 20 via the primary cell (Pcell) and the secondary cell (Scell). Figure 1 In the example of , the terminal 20 establishes a Radio Resource Control (RRC) connection with the base station 10 - 1 .

[0029] In the case of DC, there may be a delay in communication between base station 10-1 and base station 10-2. Therefore, it is difficult to notify base station 10-2 via the backhaul link (e.g., a wired or wireless link connecting base station 10-1 and base station 10-2) of the uplink control information received in the Pcell of base station 10-1 (e.g., uplink control information (Uplink Control Information: UCI)) and reflect it in the scheduling of the Scell subordinate to base station 10-2. Therefore, in DC, in addition to the Pcell of base station 10-1, one carrier subordinate to base station 10-2 can be set as the primary Scell (Primary Scell (PScell)) to support PUCCH transmission through the PScell. In this case, terminal 20 sends UCI to base station 10-2 via the PScell.

[0030] In Figure 1 's example, terminal 20 sets an Scell for base station 10-1 in addition to the Pcell. In addition, terminal 20 sets an Scell for base station 10-2 in addition to the PScell. Terminal 20 sends the UCI of each carrier subordinate to base station 10-1 through the PUCCH of the Pcell. In addition, terminal 20 sends the UCI of each carrier subordinate to base station 10-2 through the PUCCH of the PScell. In Figure 1 's example, the cell group (CG) subordinate to base station 10-1 can also be referred to as the master cell group (Master Cell-Group (MCG)). The cell group subordinate to base station 10-2 can also be referred to as the secondary cell group (Secondary Cell-Group (SCG)).

[0031] In the case of performing DC, terminal 20 can also perform PUCCH transmission via the Pcell, PScell, and / or PUCCH-Scell. Generally, it is not assumed that terminal 20 performs PUCCH transmission via an Scell other than the Pcell, PScell, and PUCCH-Scell.

[0032] <PUCCH Carrier Switching>

[0033] In the time division duplex (Time Division Duplex (TDD)) mode, PUCCH carrier switching is being studied as a method for reducing the delay of HARQ-ACK feedback.

[0034] Figure 2 is a diagram showing an example of PUCCH carrier switching. In Figure 2 's example, the base station and the terminal communicate via cell 1 and cell 2. In Figure 2In the example, cell 1 is Pcell and cell 2 is Scell. Figure 2 In the example of , downlink (DL) time slots and uplink (UL) time slots in each cell are shown.

[0035] exist Figure 2 In the example, the terminal receives data at S101 (performs reception on the Physical Downlink Shared Channel (PDSCH)). The terminal attempts to transmit HARQ-ACK for the data received in S101 at S102. However, at S102, the time slot of cell 1 is a downlink (DL) time slot. Therefore, when the terminal transmits HARQ-ACK in cell 1, the transmission of HARQ-ACK must be delayed until the transmission timing of the PUCCH in the uplink (UL) time slot (e.g., Figure 2 The timing of S103 in the uplink (UL) time slot may also be referred to as the PUCCH transmission opportunity.

[0036] exist Figure 2 In the example, at the timing of S102, the time slot of cell 2 is the UL time slot. Figure 2 In the example above, if the terminal can transmit a HARQ-ACK for the data received in S101 during the PUCCH transmission opportunity scheduled in S102 of cell 2, the HARQ-ACK transmission latency can be reduced. In URLLC, low latency is particularly required within the wireless section. Therefore, 3GPP is studying PUCCH carrier switching, which allows the terminal to switch the carrier that transmits the PUCCH, as an extension of URLLC technology.

[0037] In the following embodiments, “same timing” may be completely identical timing, or may be that all or part of time resources (eg, one or more symbols (or resources of a time unit shorter than a symbol)) are identical or overlap.

[0038] PUCCH carrier switching may also involve: when a terminal wishes to transmit a PUCCH at a specific transmission timing on a Pcell (which may also be a PScell or PUCCH-Scell), since the timestamp of the specific transmission timing on the Pcell (which may also be a PScell or PUCCH-Scell) is a DL timestamp, the terminal switches the cell for PUCCH transmission from the Pcell (which may also be a PScell or PUCCH-Scell) to any Scell (in the case of a PScell, an Scell other than the PScell; in the case of a PUCCH-Scell, an Scell other than the PUCCH-Scell) whose timestamp is the same as the specific transmission timing as a UL timestamp. Furthermore, in embodiments of the present invention, the specific transmission timing is not limited to a timestamp. For example, the specific transmission timing may be a timing in subframe units or a timing in symbol units.

[0039] Two methods for implementing PUCCH carrier switching are under investigation. The first method involves the base station dynamically indicating to the terminal the carrier to use for PUCCH transmission. The second method involves the base station semi-statically configuring the carrier to use for PUCCH transmission for the terminal. In the following embodiments, "PUCCH transmission" and "PUCCH transmission" may also refer to the transmission of uplink control information via the PUCCH.

[0040] The terminal may also notify the base station of terminal capability information (UE capability), where the terminal capability information specifies information related to the capability of the terminal related to PUCCH transmission.

[0041] For example, as terminal capability information of a terminal, information indicating whether the terminal supports switching of settings related to the transmission of control information may be specified. Switching of settings related to the transmission of control information may, for example, be switching of resources (e.g., carriers or cells) used for the transmission of control information. Switching of resources used for the transmission of control information may also be referred to as "PUCCH carrier switching." Furthermore, as terminal capability information of a terminal, information indicating the application of dynamic PUCCH carrier switching and / or semi-static PUCCH carrier switching may also be specified.

[0042] The configuration operation of semi-static PUCCH carrier switching can also be based on the RRC that sets the PUCCH cell timing pattern of the PUCCH cell to which semi-static PUCCH carrier switching is applied. In addition, the configuration operation of semi-static PUCCH carrier switching can also be supported between cells with different parameter sets.

[0043] In PUCCH carrier switching, the setting of PUCCH resources can also be performed for each UL BWP (Uplink Bandwidth Part) (for example, for each candidate cell and each UL BWP of the candidate cell).

[0044] In the case of PUCCH carrier switching based on dynamic indication of control information, the K1 value (offset) from PDSCH to HARQ-ACK can also be interpreted based on the parameter set of the target PUCCH cell dynamically indicated. In addition, the control information can also be control information such as Downlink control information (DCI) that schedules PUCCH. Furthermore, the parameter set can also be understood as a time slot or Subcarrier Spacing (SCS).

[0045] In URLLC, research is conducted on the functional enhancement of HARQ-ACK codebook (HARQ-ACK CB) feedback for terminals. Hereinafter, the outlines of Type 1 HARQ-ACK CB and Type 2 HARQ-ACK CB are described (for detailed content, refer to Non-Patent Document 1).

[0046] <CG Enhancements in Rel-18 XR>

[0047] At the RAN1 #111 meeting, agreement was reached on supporting CG enhancements for Rel-18 XR.

[0048] · Agreement

[0049] Support dynamic indication of one or more unused CG PUSCH occasions based on the terminal's Uplink Control Information (UCI).

[0050] For example, in the case where there are unused CG PUSCH opportunities, the terminal may also use UCI to notify the unused CG PUSCH opportunities.

[0051] ·desirable

[0052] Supports multiple CG PUSCH opportunities (multiple CG PUSCH) within a single CG PUSCH configuration period.

[0053] For example, when a plurality of CG PUSCHs are configured for a terminal, a plurality of CG PUSCH opportunities may be configured during a period in which one of the CG PUSCHs is configured.

[0054] In addition, unused may also include not used. A CG PUSCH opportunity may also be referred to as a CG PUSCH transmission opportunity. The period for which a CG PUSCH is configured may also be referred to as a CG PUSCH period or a CG period. The period may also be periodic.

[0055] <CG PUSCH>

[0056] As mentioned above, in NR, Rel-16 specifies the configuration of CG PUSCH (for example, Non-Patent Document 2). CG PUSCH includes Type 1 CG PUSCH and Type 2 CG PUSCH.

[0057] Type 1 CG PUSCH

[0058] The transmission parameters of Type 1 CG PUSCH are provided by "configuredGrantConfig", "pusch-Config", and "rrc-ConfiguredUplinkGrant". The activation and deactivation of Type 1 CG PUSCH depend on RRC-configuration and do not depend on Downlink Control Information (DCI).

[0059] Type 2 CG PUSCH

[0060] The transmission parameters of Type 2 CG PUSCH are provided by "configuredGrantConfig", "pusch-Config", and "activation DCI". The activation and deactivation of Type 2 CG PUSCH depend on RRC-configuration and DCI. One DCI can activate one CG PUSCH and can deactivate multiple CG PUSCHs.

[0061] <CG PUSCH configurations>

[0062] Figure 3 and Figure 4 is a diagram showing the parameters representing configuredGrantConfig. Figure 4 The parameters shown are connected after Figure 3 the parameters shown. Figure 3 and Figure 4 the parameters of configuredGrantConfig shown are used to set the uplink transmission with the configured grant.

[0063] <Verification of activation DCI>

[0064] In Rel-17, when the TDRA (Time Domain Resource Assignment) field of the DCI format represents a row containing a single SLIV (Start and Length Indicator Value), the terminal verifies the configured UL grant Type 2 PDCCH (UL grant Type 2 PDCCH) for scheduling activation or scheduling release (for example, refer to Section 10.2 of 3GPP TS38.213 V17.3.0). In other words, when the DCI shows multiple SLIVs through the TDRA field, the terminal cannot perform validation of the activation DCI. Additionally, the SLIV defines the start symbol and the number of consecutive symbols.

[0065] <Analysis>

[0066] As described in <CG extensions in Rel-18 XR> above, for Rel-18 XR, an agreement was reached to support CG extensions. However, in high-capacity communications such as Rel-18 XR, there is still room for the following research regarding the setting of multiple CG PUSCH opportunities in a single CG PUSCH setting.

[0067] · Research 1

[0068] Type 1 CG PUSCH association settings

[0069] Study 2

[0070] Type 2 CG PUSCH association setup and verification of DCI activation

[0071] In addition, as described in <Verification of Activation DCI>, in the current specification, when DCI indicates multiple SLIVs using the TDRA field, the terminal cannot verify the activation DCI.

[0072] Study 3

[0073] Possibility of limiting multiple CG PUSCH opportunities in one CG period

[0074] Based on the above studies 1-3, proposals 1-3 are described below.

[0075] <Proposal 1>

[0076] Proposal 1 appropriately sets multiple CG PUSCH opportunities in large-capacity communications by defining the settings associated with Type 1 CG PUSCH in Study 1. Proposal 1 may also include Option 1 and Option 2.

[0077] <Proposal 1 - Option 1>

[0078] In Option 1 of Proposal 1, for Type 1 CG PUSCH setting, multiple CGPUSCH opportunities are not supported in one CG period.

[0079] ·Example 1

[0080] The terminal does not expect "timeDomainAllocation" in "rrc-ConfiguredUplinkGrant" indicating multiple SLIVs. "rrc-ConfiguredUplinkGrant" is an RRC parameter related to the configuration of uplink grants, and "timeDomainAllocation" is a parameter related to the configuration of time resources.

[0081] ·Example 2

[0082] The terminal may not expect that the RRC parameter indicating the number of CG PUSCH opportunities in one CG period is set for Type 1 CG PUSCH.

[0083] In the operations of Examples 1 and 2 above, for example, the base station may also control the validity and invalidity of multiple CG PUSCH opportunities. Here, it is assumed that the terminal can handle multiple CG PUSCH opportunities in Type 1 CG PUSCH.

[0084] When the base station disables the multiple CG PUSCH opportunities function in Type 1 CG PUSCH, the "rrc-ConfiguredUplinkGrant" does not include the "timeDomainAllocation" indicating multiple SLIVs. Since the "rrc-ConfiguredUplinkGrant" does not include the "timeDomainAllocation" indicating multiple SLIVs, the terminal does not support multiple CG PUSCH opportunities.

[0085] In addition, the base station does not set the RRC parameter indicating the number of CG PUSCH opportunities for Type 1 CG PUSCH. Since the RRC parameter indicating the number of CG PUSCH opportunities is not set for Type 1 CG PUSCH, the terminal does not support multiple CG PUSCH opportunities.

[0086] In addition, the word "expect" can be rewritten as "concept" or "decision." The words "valid" and "invalid" can also be rewritten as "activate" and "deactivate."

[0087] <Proposal 1 - Option 2>

[0088] In Option 2 of Proposal 1, for Type 1 CG PUSCH setting, multiple CGPUSCH opportunities are supported in one CG period.

[0089] ·Example 1

[0090] When "timeDomainAllocation" in "rrc-ConfiguredUplinkGrant" indicates multiple SLIVs, the terminal expects (supports) multiple CG PUSCH opportunities in one CG period.

[0091] ·Example 2

[0092] When the number of CG PUSCH opportunities in one CG period is set for Type 1 CG PUSCH, the terminal expects (supports) multiple CG PUSCH opportunities in one CG period.

[0093] When the terminal expects multiple CG PUSCH opportunities in Example 1 or Example 2, it expects one or more of the following conditions to be met. Conditions can also be referred to as states.

[0094] Condition 1

[0095] Dynamic indication of unused CG PUSCH opportunities is enabled for Type 1 CG PUSCH configuration.

[0096] Condition 2

[0097] The physical priority configured for the Type 1 CG PUSCH is indicated as either High or Low.

[0098] For example, "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set. In this case, the physical priority configured for Type 1 CG PUSCH is set to Low in the terminal.

[0099] For example, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "0". Alternatively, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "1".

[0100] Condition 3

[0101] Setting repetition (Type A or Type B) is not set for Type 1 CG PUSCH.

[0102] For example, "rep-K" is not set in "ConfiguredGrantConfig." Alternatively, "rep-K" is set to "1." In addition, "rep-K" is a parameter indicating the number of repetitions of the CG PUSCH.

[0103] For example, "pusch-RepTypeIndicator" is not set in "rrc-ConfiguredUplinkGrant".

[0104] For example, "pusch-RepTypeIndicator" is not set as "pusch-RepTypeA" in "rrc-ConfiguredUplinkGrant." Alternatively, "pusch-RepTypeIndicator" is not set as "pusch-RepTypeB" in "rrc-ConfiguredUplinkGrant."

[0105] The "pusch-RepTypeIndicator" parameter indicates the repetition type. Repetition type A can also be interpreted as a method in which the PUSCH allocated within a slot is repeatedly transmitted. In other words, the PUSCH is 14 symbols or less and cannot be allocated across multiple slots (adjacent slots).

[0106] On the other hand, repetition type B can also be interpreted as repeated transmission of a PUSCH where there is a possibility that a PUSCH of 15 or more symbols may be allocated. In this embodiment, such a PUSCH can be allocated across multiple slots.

[0107] Condition 4

[0108] Multi-TPR transmission is not configured for Type 1 CG PUSCH configuration. TPR stands for Transmission and Reception Point.

[0109] For example, "pathlossReferenceIndex2" and / or "srs-ResourceIndicator2" and / or "precodingAndNumberOfLayers2" are not set in "rrc-ConfiguredUplinkGrant." In other words, parameters related to the second SRS are not set for the terminal. SRS is short for Sounding Reference Signal.

[0110] In addition, "pathlossReferenceIndex2" is a parameter indicating the reference signaling used as the PUSCH path loss reference for the second SRS resource set. "srs-ResourceIndicator2" is a parameter indicating the SRS resource used in the second SRS resource set. "precodingAndNumberOfLayers2" is a parameter indicating the precoding and number of layers for the second SRS resource set.

[0111] Condition 5

[0112] “cg-SDT-Configuration” is not set in “rrc-ConfiguredUplinkGrant”.

[0113] "cg-SDT-Configuration" is a parameter related to the configuration of SDT. SDT is short for Small Data Transmission. SDT transmits the CG PUSCH in the RRC deactivated state.

[0114] Condition 6

[0115] The CG PUSCH period is greater than X symbols. Alternatively, the CG PUSCH period is greater than the number of time slots of the indicated multiple SLIVs. In other words, the multiple CG PUSCH opportunities are set with the CG PUSCH period so as to be transmitted within the CG period.

[0116] Modification

[0117] Even if one or more of the above conditions are not met, the terminal may also send a CG PUSCH opportunity in a CG period.

[0118] <Summary of Proposal 1>

[0119] The terminal determines whether to support multiple CG PUSCH opportunities for Type 1 CG PUSCH in one period based on parameters in higher layer signaling. This operation enables the terminal to appropriately configure multiple CG PUSCH opportunities in large-volume communications.

[0120] <Proposal 2>

[0121] Proposal 2 specifies the configuration of Type 2 CG PUSCH association and verification of DCI activation in Study 2, thereby appropriately setting multiple CG PUSCH opportunities in high-capacity communications.

[0122] In Proposal 2, multiple CG PUSCH opportunities are supported in one CG period for Type 2 CG PUSCH configuration. Proposal 2 has the following assumptions 1 and 2.

[0123] <Proposal 2-Assumption 1>

[0124] TDRAs for multiple CG PUSCH opportunities in one CG period are indicated by independent SLIVs in one TDRA row.

[0125] Figure 5 This is a diagram showing an example of a TDRA table. In the terminal, for example, through parameters such as RRC, Figure 5 The TDRA table shown is semi-statically entered. Figure 5As shown, the TDRA table has multiple SLIVs for one row. The multiple SLIVs correspond to the SLIVs of multiple CG PUSCH opportunities.

[0126] When the DCI (TDRA field) indicates a TDRA row index indicating one or more SLIVs, the terminal verifies the DCI as a Type 2 CG PUSCH activation DCI. The terminal determines multiple CG PUSCH opportunities (eg, time slots) in one CG period based on the multiple SLIVs.

[0127] When the terminal is able to verify DCI as activation DCI representing TDRA row indices of multiple SLIVs and send multiple CG PUSCH opportunities based on multiple SLIVs in one CG period, it is expected that one or more of the following conditions will be met.

[0128] Condition 1

[0129] Dynamic indication of unused CG PUSCH opportunities is enabled for Type 2 CG PUSCH configuration.

[0130] Condition 2

[0131] The physical priority of the Type 1 CG PUSCH setting is indicated as either High or Low.

[0132] For example, "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set. In this case, the terminal sets the physical priority of Type 1 CG PUSCH configuration to Low.

[0133] For example, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "0". Alternatively, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "1".

[0134] Condition 3

[0135] Repetition (Type A or Type B) is not set for Type 2 CG PUSCH setting.

[0136] For example, "numberOfRepetitions" exists in the TDRA table. Or, "rep-K" is not set in "ConfiguredGrantConfig".

[0137] For example, when the active DCI format is DCI 0_1 or DCI 0_2, 'pusch-RepTypeIndicatorDCI-0-1' or 'pusch-RepTypeIndicatorDCI-0-2' in 'PUSCH-Config' is not set. Alternatively, when the active DCI format is DCI 0_1 or DCI 0_2, 'pusch-RepTypeA' or 'pusch-RepTypeB' is not set.

[0138] Furthermore, "PUSCH-Config" is an information element used to configure terminal-specific PUSCH parameters applicable within a specific bandwidth part (BWP). "pusch-RepTypeIndicatorDCI-0-1" / "pusch-RepTypeIndicatorDCI-0-2" are parameters indicating whether the terminal operates according to "Repetition type A" or "Repetition type B" for PUSCHs scheduled using DCI formats 0_1 / 0_2.

[0139] Condition 4

[0140] Multi-TPR transmission is not configured for Type 2 CG PUSCH configuration.

[0141] For example, the value of the SRS resource set indicator field of the activation DCI indicates '00' or '01.' In other words, the value of the SRS resource set indicator field of the activation DCI indicates a certain TPR.

[0142] For example, "powerControlLoopToUse2" and / or "mappingPattern" are not set in "ConfiguredGrantConfig".

[0143] In addition, "powerControlLoopToUse2" is a parameter related to closed-loop control applied to the second SRS resource set. When two SRS resource sets are configured, "mappingPattern" is a parameter indicating whether the terminal should follow the cyclic mapping mode or the sequential mapping mode.

[0144] Condition 5

[0145] The CG PUSCH period is greater than X symbols. Alternatively, the CG PUSCH period is greater than the number of time slots of the indicated multiple SLIVs. In other words, the multiple CG PUSCH opportunities are configured with the CG PUSCH period so as to be transmitted within the CG period.

[0146] Modification

[0147] If one or more of the above conditions are not met, the terminal may verify the DCI as activated DCI. In addition, the terminal may send only one CGPUSCH opportunity in one CG period based on the first or last SLIV.

[0148] <Proposal 2-Assumption 2>

[0149] The TDRAs of multiple CG PUSCH opportunities in one CG period may also be determined based on the TDRA of the first CG PUSCH opportunity and the number of CG PUSCH opportunities in one CG period. Assumption 2 of Proposal 2 is further divided into two assumptions 2-1 and 2-1.

[0150] <Proposal 2-Assumption 2-1>

[0151] The number of CG PUSCH opportunities in a CG period is indicated by activating DCI.

[0152] For example, the terminal expects the TDRA of the first CG PUSCH opportunity and the number of CG PUSCH opportunities based on the activation DCI. The terminal determines the TDRA of CG PUSCH opportunities after the first CG PUSCH opportunity based on the TDRA of the first CG PUSCH opportunity and the number of CG PUSCH opportunities.

[0153] The terminal is able to verify DCI as an activation DCI indicating the number of CG PUSCH opportunities in one CG period. When sending multiple CG PUSCH opportunities based on one SLIV or the initial SLIV among multiple SLIVs in one CG period, it is expected that one or more of the following conditions will be met.

[0154] Condition 1

[0155] For Type 2 CG PUSCH configuration, multiple CG PUSCH opportunities in one CG period are configured to be valid.

[0156] Condition 2

[0157] Dynamic indication of unused CG PUSCH opportunities is enabled for Type 2 CG PUSCH configuration.

[0158] Condition 3

[0159] The physical priority of the Type 1 CG PUSCH setting is indicated as either High or Low.

[0160] For example, "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set. In this case, the terminal sets the physical priority of Type 1 CG PUSCH configuration to Low.

[0161] For example, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "0". Alternatively, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "1".

[0162] Condition 4

[0163] Repetition (Type A or Type B) is not set for Type 2 CG PUSCH setting.

[0164] For example, "numberOfRepetitions" exists in the TDRA table. Or, "rep-K" is not set in "ConfiguredGrantConfig".

[0165] For example, when the active DCI format is DCI 0_1 or DCI 0_2, 'pusch-RepTypeIndicatorDCI-0-1' or 'pusch-RepTypeIndicatorDCI-0-2' in 'PUSCH-Config' is not set. Alternatively, when the active DCI format is DCI 0_1 or DCI 0_2, 'pusch-RepTypeA' or 'pusch-RepTypeB' is not set.

[0166] Condition 5

[0167] Multi-TPR transmission is not configured for Type 2 CG PUSCH configuration.

[0168] For example, the value of the SRS resource set indicator field of the activation DCI indicates '00' or '01.' In other words, the value of the SRS resource set indicator field of the activation DCI indicates a certain TPR.

[0169] For example, "powerControlLoopToUse2" and / or "mappingPattern" are not set in "ConfiguredGrantConfig".

[0170] Condition 6

[0171] The CG PUSCH period is greater than X symbols. Alternatively, the CG PUSCH period is greater than the number of time slots of the indicated multiple SLIVs. In other words, the multiple CG PUSCH opportunities are set with the CG PUSCH period so as to be transmitted within the CG period.

[0172] Modification

[0173] When one or more of the above conditions are not met, the terminal may verify the DCI as activated DCI. In addition, the terminal may only send one CG PUSCH opportunity in one CG period.

[0174] <Proposal 2-Assumption 2-2>

[0175] The number of CG PUSCH opportunities in one CG period is indicated by the Type 2 CG PUSCH configuration. For example, the number of CG PUSCH opportunities in one CG period is indicated by a parameter of higher layer signaling such as "ConfiguredGrantConfig".

[0176] When the number of CG PUSCH opportunities in one CG period is set to "ConfiguredGrantConfig", the terminal expects to satisfy one or more of the following conditions.

[0177] Condition 1

[0178] The dynamic indication of unused CG PUSCH opportunities is set to valid for Type 2 CG PUSCH configuration.

[0179] Condition 2

[0180] The physical priority of the Type 1 CG PUSCH setting is indicated as either High or Low.

[0181] For example, "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set. In this case, the terminal sets the physical priority of Type 1 CG PUSCH configuration to Low.

[0182] For example, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "0". Alternatively, the "phy-PriorityIndex" of "ConfiguredGrantConfig" is not set to "1".

[0183] Condition 3

[0184] Repetition (Type A or Type B) is not set for Type 2 CG PUSCH setting.

[0185] For example, "numberOfRepetitions" exists in the TDRA table. Or, "rep-K" is not set in "ConfiguredGrantConfig".

[0186] For example, when the active DCI format is DCI 0_1 or DCI 0_2, 'pusch-RepTypeIndicatorDCI-0-1' or 'pusch-RepTypeIndicatorDCI-0-2' in 'PUSCH-Config' is not set. Alternatively, when the active DCI format is DCI 0_1 or DCI 0_2, 'pusch-RepTypeA' or 'pusch-RepTypeB' is not set.

[0187] Condition 4

[0188] Multi-TPR transmission is not configured for Type 2 CG PUSCH configuration.

[0189] For example, the value of the SRS resource set indicator field of the activation DCI indicates '00' or '01.' In other words, the value of the SRS resource set indicator field of the activation DCI indicates a certain TPR.

[0190] For example, "powerControlLoopToUse2" and / or "mappingPattern" are not set in "ConfiguredGrantConfig".

[0191] Condition 5

[0192] The CG PUSCH period is greater than X symbols. Alternatively, the CG PUSCH period is greater than the number of slots of the indicated multiple SLIVs. In other words, the multiple CG PUSCH opportunities are configured with the CG PUSCH period so as to be transmitted within the CG period.

[0193] Modification

[0194] If one or more of the above conditions are not met, the terminal may also send a CG PUSCH opportunity in one CG period.

[0195] <Summary of Proposal 2>

[0196] The terminal determines each of the multiple CGPUSCH opportunities for Type 2 CG PUSCH in one period based on the independent TDRA. This operation enables the terminal to appropriately set multiple CG PUSCH opportunities in large-capacity communication.

[0197] Furthermore, the terminal determines each of the multiple CG PUSCH opportunities for Type 2 CG PUSCH in one period based on the TDRA in the first CG PUSCH opportunity and the number of multiple CG PUSCH opportunities. This operation enables the terminal to appropriately set multiple CG PUSCH opportunities in large-volume communications.

[0198] <Proposal 3>

[0199] Proposal 3 appropriately sets multiple CG PUSCH opportunities in large-capacity communications by defining restrictions on multiple CG PUSCH opportunities in one CG period in Study 3. Proposal 3 may also include Option 1 and Option 2.

[0200] <Proposal 3 - Option 1>

[0201] When "rep-K" is set to the value K in "ConfiguredGrantConfig" and multiple PUSCH opportunities are determined in one CG period for CG PUSCH configuration as described in Proposals 1 and 2, the terminal performs the following transmission operations of Alt.1-Alt.3.

[0202] In addition, when "numberOfRepetitions" exists in the TDRA table and a plurality of PUSCH opportunities are determined in one CG period for CG PUSCH configuration as described in Proposals 1 and 2, the terminal performs the following transmission operations of Alt.1-Alt.3.

[0203] <Proposal 3 - Option 1 - Alt. 1>

[0204] In Alt.1 of Proposal 3, the combined operation of repetition and multiple CG PUSCH opportunities is not allowed in one CG period, and multiple CG PUSCH opportunities take precedence over repetition.

[0205] For example, each of the multiple CG PUSCH opportunities has only one repetition. For example, the terminal transmits multiple CG PUSCH opportunities in one CG period, and performs one repetition in each of the multiple CG PUSCH opportunities.

[0206] <Proposal 3 - Option 1 - Alt. 2>

[0207] In Alt.2 of Proposal 3, repeated joint operation with multiple CG PUSCH opportunities is allowed during one CG period.

[0208] For example, each of multiple CG PUSCH opportunities has K repetitions. For example, the terminal transmits multiple CG PUSCH opportunities in one CG period, performing K repetitions in each of the multiple CG PUSCH opportunities. If the number of multiple CG PUSCH opportunities is N, the terminal transmits N*K PUSCHs in one CG period.

[0209] <Proposal 3 - Option 1 - Alt. 3>

[0210] In Alt.3 of Proposal 3, the joint operation of repetition and multiple CG PUSCH opportunities is not allowed during one CG period, and repetition takes precedence over multiple CG PUSCH opportunities.

[0211] For example, one CG PUSCH opportunity is transmitted in one CG period, and one CG PUSCH opportunity has K repetitions. For example, the terminal transmits one CG PUSCH opportunity in one CG period, and one CG PUSCH opportunity performs K repetitions.

[0212] <Proposal 3 - Option 2>

[0213] In Option 2 of Proposal 3, other possible variations of TDRA for multiple CG PUSCH opportunities in one CG period are described.

[0214] ·Example 1

[0215] The number of CG PUSCH opportunities in one slot is limited to a maximum of X.

[0216] ·Example 2

[0217] Multiple CG PUSCH opportunities in one CG period are limited to a maximum of Y time slots.

[0218] Modification

[0219] The values of X and / or Y may also be defined by a specification. The values of X and / or Y may also be set via parameters in higher layer signaling such as RRC. The values of X and / or Y may also be reported via terminal capability information (UE capability).

[0220] The candidate values of X and / or Y may also depend on the frequency range (e.g., FR1, FR2-1, FR2-2) and / or SCS (e.g., 15 / 30 / 60 / 120 / 240 / 960 kHz SCS) and / or the number of CG PUSCH settings and / or the periodicity of the CG PUSCH settings.

[0221] <Summary of Proposal 3>

[0222] The terminal determines the number of CG PUSCH opportunities in one period and the repetition of CG PUSCH opportunities based on the parameters of the higher layer signaling. This operation enables appropriate setting of multiple CG PUSCH opportunities in large-volume communications.

[0223] Furthermore, regarding TDRA, the terminal limits the number of CG PUSCH opportunities in one slot to a maximum of X. This operation enables appropriate setting of multiple CG PUSCH opportunities in large-capacity communications.

[0224] In addition, regarding TDRA, the terminal limits the number of CG PUSCH opportunities in one CG period to a maximum of Y slots. This operation enables appropriate setting of multiple CG PUSCH opportunities in large-capacity communications.

[0225] <Modification>

[0226] The terminal can also dynamically update the number of CG PUSCH opportunities in a CG period. The terminal can also dynamically update the TDRA used for multiple CG PUSCH opportunities in a CG period. Dynamic updates can also be performed through existing DCI and / or new DCI and / or activated DCI and / or MAC CE. MAC CE is the abbreviation for Media Access Control Control Element.

[0227] The proposal, option, and / or Alt to be used can also be set by parameters in higher-layer signaling. The proposal, option, and / or Alt to be used can also be reported by the terminal as terminal capability information. The proposal, option, and / or Alt to be used can also be defined by a specification. The proposal, option, and / or Alt to be used can also be defined by a combination of parameters in higher-layer signaling, terminal capability information, and specifications.

[0228] <Terminal Capabilities>

[0229] The terminal may also report the following terminal capability information to the base station.

[0230] Defines whether PUSCH repetition and joint operation of multiple CG PUSCH opportunities are supported during a CG period

[0231] The prerequisite functions and / or capabilities for the terminal capability of multiple CG PUSCH opportunities in one CG period have one or more of the following situations:

[0232] Scheduling multiple PUSCHs with a single DCI (Rel-17 capability)

[0233] Multiple active configured grant configurations for BWP of serving cell

[0234] Reporting of dynamic representation of unused CG PUSCH opportunities based on UCI

[0235] <Structure of Base Station>

[0236] Figure 6 1 is a block diagram showing an example of the structure of the base station 10. The base station 10 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. The base station 10 communicates with the terminal 20 (refer to Figure 7 ) for communication.

[0237] The transmission unit 101 transmits a downlink (DL) signal to the terminal 20. For example, the transmission unit 101 transmits the DL signal under the control of the control unit 103.

[0238] DL signals may include, for example, downlink data signals and control information (e.g., Downlink Control Information (DCI)). Furthermore, DL signals may include information indicating scheduling related to signal transmission by terminal 20 (e.g., UL grant). DL signals may also include higher-layer control information (e.g., Radio Resource Control (RRC) control information). DL signals may also include reference signals.

[0239] Channels used for transmitting DL signals may include, for example, data channels and control channels. For example, data channels may include the PDSCH (Physical Downlink Shared Channel), and control channels may include the PDCCH (Physical Downlink Control Channel). For example, the base station 10 transmits control information to the terminal 20 using the PDCCH and transmits downlink data signals using the PDSCH.

[0240] Reference signals included in downlink signals may include, for example, a demodulation reference signal (DMRS), a phase tracking reference signal (PTRS), a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), and a positioning reference signal (PRS). For example, reference signals such as DMRS and PTRS may also be used to demodulate downlink data signals and transmitted using the PDSCH.

[0241] The receiving unit 102 receives an uplink (UL) signal transmitted from the terminal 20. For example, the receiving unit 102 receives the UL signal under the control of the control unit 103.

[0242] The control unit 103 controls the communication operation of the base station 10 including the transmission processing of the transmission unit 101 and the reception processing of the reception unit 102 .

[0243] For example, control section 103 obtains information such as data and control information from an upper layer and outputs it to transmission section 101. Control section 103 also outputs data and control information received from reception section 102 to an upper layer.

[0244] For example, the control unit 103 allocates resources (or channels) for transmitting and receiving downlink signals and / or resources for transmitting and receiving uplink signals based on signals (e.g., data and control information) received from the terminal 20 and / or data and control information obtained from higher layers. Information regarding the allocated resources may also be included in the control information transmitted to the terminal 20.

[0245] The control unit 103 assumes PUCCH resources as an example of resource allocation for transmitting and receiving UL signals. Information related to PUCCH configuration such as the PUCCH cell timing mode (PUCCH configuration information) may be notified to the terminal 20 via RRC.

[0246] <Terminal Structure>

[0247] Figure 7 2 is a block diagram showing an example of the configuration of the terminal 20. The terminal 20 includes, for example, a receiving unit 201, a transmitting unit 202, and a control unit 203. The terminal 20 communicates with the base station 10, for example, by radio.

[0248] The receiving unit 201 receives a DL signal transmitted from the base station 10. For example, the receiving unit 201 receives the DL signal under the control of the control unit 203.

[0249] The transmitting unit 202 transmits a UL signal to the base station 10. For example, the transmitting unit 202 transmits the UL signal under the control performed by the control unit 203.

[0250] The UL signal may include, for example, uplink data signals and control information (eg, UCI). For example, it may also include information related to the processing capabilities of the terminal 20 (eg, UE capability). Furthermore, the UL signal may also include a reference signal.

[0251] Channels used for UL signal transmission may include, for example, data channels and control channels. For example, data channels may include the PUSCH (Physical Uplink Shared Channel), and control channels may include the PUCCH (Physical Uplink Control Channel). For example, terminal 20 uses the PUCCH to receive control information from base station 10 and uses the PUSCH to transmit uplink data signals.

[0252] Reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, reference signals such as DMRS and PTRS may also be used to demodulate uplink data signals and transmitted using an uplink channel (e.g., PUSCH).

[0253] The control unit 203 controls the communication operation of the terminal 20 including the reception process in the reception unit 201 and the transmission process in the transmission unit 202 .

[0254] For example, control section 203 obtains information such as data and control information from an upper layer and outputs it to transmission section 202. Control section 203 may also output data and control information received from reception section 201, for example, to an upper layer.

[0255] For example, the control unit 203 controls the transmission of information fed back to the base station 10. The information fed back to the base station 10 may include, for example, HARQ-ACK, channel state information (CSI), and a scheduling request (SR). The information fed back to the base station 10 may also be included in the Unified Communications Information (UCI). The UCI may also be transmitted in PUCCH resources.

[0256] The control unit 203 configures PUCCH resources based on configuration information received from the base station 10 (e.g., configuration information such as the PUCCH cell timing mode notified via RRC and / or DCI). The control unit 203 determines the PUCCH resources used to transmit feedback information to the base station 10. Under control by the control unit 203, the transmission unit 202 transmits the feedback information to the base station 10 using the PUCCH resources determined by the control unit 203.

[0257] The channels used for transmitting DL signals and UL signals are not limited to the examples above. For example, the channels used for transmitting DL signals and UL signals may include the RACH (Random Access Channel) and the PBCH (Physical Broadcast Channel). The RACH may also be used to transmit downlink control information (DCI) including the Random Access Radio Network Temporary Identifier (RA-RNTI).

[0258] The control unit 203 determines whether to support multiple uplink signal opportunities for Type 1 CG PUSCH in a single period based on parameters in higher layer signaling. For example, if the "rrc-ConfiguredUplinkGrant" does not include "timeDomainAllocation" indicating multiple SLIVs, the control unit 203 determines not to support multiple uplink signal opportunities for Type 1 CG PUSCH in a single period. If the "rrc-ConfiguredUplinkGrant" includes "timeDomainAllocation" indicating multiple SLIVs, the control unit 203 determines to support multiple uplink signal opportunities for Type 1 CG PUSCH in a single period.

[0259] When determining an opportunity not to support multiple uplink signals for Type 1 CG PUSCH, the control unit 203 assumes that one or more of the conditions described in <Proposal 1 - Option 2> are satisfied.

[0260] Furthermore, control unit 203 determines each of the multiple uplink signal opportunities within a period based on independent time resource allocation information. When determining each of the multiple uplink signal opportunities within a period based on independent time resource allocation information and transmitting multiple uplink signal opportunities, control unit 203 assumes that one or more of the conditions described in <Proposal 2 - Assumption 1> are satisfied.

[0261] Furthermore, the control unit 203 determines each of the multiple uplink signal opportunities in one period based on one time resource allocation information and the number of multiple uplink signal opportunities. One time resource allocation information may be resource allocation information for the first opportunity among the multiple uplink signal opportunities.

[0262] The number of CG PUSCH opportunities in a CG period may also be indicated by an activation DCI. In this case, the control unit 203 assumes that one or more of the conditions described in <Proposal 2 - Assumption 2-1> are satisfied. Furthermore, the number of CG PUSCH opportunities in a CG period is indicated by a Type 2 CG PUSCH setting. In this case, the control unit 203 assumes that one or more of the conditions described in <Proposal 2 - Assumption 2-2> are satisfied.

[0263] Furthermore, the control unit 203 determines the opportunities of uplink signals in one period and the repetition of the opportunities of uplink signals based on the parameters of the higher layer signaling.

[0264] Furthermore, the control unit 203 determines the time resource allocation information so that the number of CG PUSCH opportunities in one time slot is limited to a maximum of X.

[0265] In addition, the control unit 203 determines the time resource allocation information so that the number of CG PUSCH opportunities in one CG period is limited to a maximum of Y time slots.

[0266] The above describes the present disclosure. Furthermore, the distinctions between the items described above are not essential distinctions in the present disclosure. Matters described in two or more items may be combined and used as needed, or matters described in one item may be applied to matters described in another item (as long as there is no contradiction).

[0267] <Hardware structure, etc.>

[0268] The block diagrams used in the description of the above embodiments illustrate functional unit blocks. These functional blocks (structural units) are implemented by any combination of at least one of hardware and software. Furthermore, the implementation method of each functional block is not particularly limited. Specifically, each functional block can be implemented using a single device that is physically or logically combined, or by directly or indirectly (e.g., wired or wireless) connecting two or more physically or logically separate devices and utilizing these multiple devices. A functional block can also be implemented by combining one or more of these devices with software.

[0269] For example, a base station, a terminal, etc. in one embodiment of the present disclosure may also function as a computer that performs processing of the wireless communication method of the present disclosure. Figure 8 1001, memory 1002, storage 1003, communication device 1004, input device 1005, output device 1006, bus 1007, etc.

[0270] For example, a base station, a terminal, etc. in one embodiment of the present disclosure may also function as a computer that performs processing of the wireless communication method of the present disclosure. Figure 8 1001, memory 1002, storage 1003, communication device 1004, input device 1005, output device 1006, bus 1007, etc.

[0271] In the following description, the term "device" can be rewritten as circuit, equipment, unit, etc. The hardware configuration of the base station 10 and the terminal 20 may include one or more of the devices shown in the figure, or may exclude some of the devices.

[0272] Each function in the base station 10 and the terminal 20 is achieved, for example, by reading specific software (program) into hardware such as the processor 1001 and the memory 1002, and the processor 1001 performs calculations to control communication via the communication device 1004, or to control at least one of the reading and writing of data in the memory 1002 and the storage 1003.

[0273] Processor 1001 operates an operating system, for example, to control the entire computer. Processor 1001 may also be comprised of a central processing unit (CPU) that includes interfaces with peripheral devices, a control device, a computing device, registers, and the like. For example, the aforementioned control units 103 and 203 may also be implemented by processor 1001.

[0274] In addition, the processor 1001 reads programs (program codes), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and performs various processes based on them. As a program, a program that causes a computer to perform at least a portion of the operations described in the above-mentioned embodiments is used. For example, the control unit 203 of the terminal 20 can also be implemented by a control program stored in the memory 1002 and operated by the processor 1001, and the same can be implemented for other functional blocks. The above-mentioned various processing instructions are executed by one processor 1001, but can also be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 can also be installed by one or more chips. It should be noted that the program can also be sent by the network via an electrical communication line.

[0275] Memory 1002 is a computer-readable recording medium and may be comprised of, for example, at least one of ROM (Read Only Memory), EPROM (Erasable Programmable ROM), EEPROM (Electrically Erasable Programmable ROM), RAM (Random Access Memory), and the like. Memory 1002 may also be referred to as registers, cache memory, or main memory (main storage device).

Storage 1003 may also be referred to as an auxiliary storage device. The aforementioned storage medium may also be, for example, another appropriate medium such as a database or a server that includes at least one of memory 1002 and storage 1003.

[0277] Communication device 1004 is hardware (a transmitting and receiving device) used to facilitate inter-computer communication via at least one of a wired network and a wireless network. It is also referred to as a network device, network controller, network card, or communication module. To implement at least one of frequency division duplex (FDD) and time division duplex (TDD), communication device 1004 may include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, and the like. For example, the aforementioned transmitting unit 101, receiving unit 102, receiving unit 201, and transmitting unit 202 may also be implemented by communication device 1004.

[0278] The input device 1005 is an input device that receives input from the outside (e.g., a keyboard, mouse, microphone, switch, button, sensor, etc.). The output device 1006 is an output device that outputs to the outside (e.g., a display, speaker, LED light, etc.). Alternatively, the input device 1005 and the output device 1006 may be integrated (e.g., a touch panel).

[0279] Furthermore, the processor 1001, memory 1002, and other devices are connected via a bus 1007 for communicating information. The bus 1007 may be configured using a single bus or different buses between the devices.

[0280] Furthermore, the base station 10 and the terminal 20 may also be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array), and may implement part or all of each functional block using this hardware. For example, the processor 1001 may be implemented using at least one of these hardware components. For example, the processor 1001 may be implemented using at least one of these hardware components.

[0281] <Information Notification and Signaling>

[0282] The notification of information is not limited to the implementation methods described in the present disclosure, and other methods may also be used. For example, the notification of information may also be implemented through physical layer signaling (e.g., DCI (Downlink Control Information), UCI (Uplink Control Information)), high-layer signaling (e.g., RRC (Radio Resource Control) signaling, MAC (Medium Access Control) signaling, broadcast information (MIB (Master Information Block), SIB (System Information Block)), other signals or a combination thereof. In addition, RRC signaling may also be referred to as an RRC message, and may also be, for example, an RRC Connection Setup message, an RRC Connection Reconfiguration message, etc.

For example, the elements of various steps in each method described in this disclosure are presented in an illustrative order, but are not limited to the specific order presented.

[0287] <Base Station Operation>

[0288] In this disclosure, specific operations performed by a base station may, depending on the circumstances, be performed by its upper node. Obviously, in a network comprising one or more network nodes including a base station, various operations performed for communication with a terminal may be performed by at least one of the base station and other network nodes other than the base station (e.g., but not limited to, an MME or a S-GW). While the example above illustrates a single other network node other than the base station, a combination of multiple other network nodes (e.g., an MME and an S-GW) is also possible.

[0289] <Input and output directions>

[0290] Information (see "Information, Signals" section) can be sent from a higher layer (or lower layer) to a lower layer (or higher layer), and can also be input and output via multiple network nodes.

[0291] <Processing of Input and Output Information, etc.>

[0292] Input and output information can be stored in a specific location (e.g., memory) or managed using a management table. Input and output information can be rewritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0293] <Judgment method>

[0294] The determination can be made based on a value represented by one bit (0 or 1), a truth value (Boolean: true or false), or by comparison of numerical values (for example, comparison with a specific value).

[0295] <Changes in method, etc.>

[0296] The various methods and implementations described in this disclosure may be used individually or in combination, and may be switched between them as the system executes the function. Furthermore, notification of specific information (e.g., notification of "X") is not limited to being performed explicitly, but may also be performed implicitly (e.g., not notifying the specific information).

[0297] While the present disclosure has been described in detail above, it will be apparent 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 the form of modifications and variations without departing from the intent and scope of the present disclosure as defined by the claims. Therefore, the descriptions in the present disclosure are for illustrative purposes only and are not intended to limit the present disclosure in any way.

[0298] <Software>

[0299] Whether software is referred to as software, firmware, middleware, microcode, hardware description language, or other names, it should be broadly construed to mean instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, executable threads, procedures, functions, etc.

[0300] Furthermore, software, instructions, information, and the like may also be transmitted and received via a transmission medium. For example, if software is transmitted from a website, server, or other remote source using at least one of a wired technology (coaxial cable, fiber optic cable, twisted pair, DSL, etc.) and a wireless technology (infrared, microwave, etc.), at least one of these wired and wireless technologies is included within the definition of a transmission medium.

[0303] Furthermore, various terms used in this disclosure and terms necessary for understanding this disclosure may be rewritten with terms having the same or similar meanings. For example, at least one of a channel and a symbol may be a signal (signaling). Furthermore, a signal may be a message. Furthermore, a component carrier (CC) may also be referred to as a carrier frequency, a cell, or a frequency carrier.

[0304] <System, Network>

[0305] As used in this disclosure, the terms "system" and "network" may be used interchangeably.

[0307] In addition, each information, parameter, etc. described in this disclosure may be represented by an absolute value, a relative value relative to a specific value, or other corresponding information. For example, a wireless resource may be indicated by an index.

[0308] The names used in the above parameters are not intended to be limiting in all respects. Furthermore, the formulas and the like used for these parameters may sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any appropriate names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in all respects.

[0309] <Base Station>

Base stations are also sometimes referred to as macrocells, small cells, femtocells, and picocells.

[0311] A base station can host one or more (for example, three) cells. When a base station hosts multiple cells, the base station's overall coverage area can be divided into multiple smaller areas, each of which can be provided with communications services by a base station subsystem (for example, a small base station (RRH) for indoor use). Terms such as "cell" or "sector" refer to a portion or the entire coverage area of at least one of a base station and a base station subsystem providing communications services within that coverage area.

[0312] <Mobile Station>

[0313] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” may be used interchangeably.

[0314] In some cases, a mobile station is also referred to by those skilled in the art as a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handheld device, a user agent, a mobile client, a client, or some other appropriate terminology.

[0315] <Base Station / Mobile Station>

[0316] At least one of the base station and the mobile station can be referred to as a transmitting device, a receiving device, a communication device, etc. Furthermore, at least one of the base station and the mobile station can be a device mounted on a mobile object, the mobile object itself, etc. The mobile object refers to a movable object, and its movement speed can be arbitrary, including situations where the mobile object is stationary.

It can be a vehicle (such as a car or aircraft), an unmanned mobile object (such as a drone or self-driving car), or a robot (manned or unmanned). Furthermore, at least one of the base station and the mobile station also includes devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0317] Furthermore, the base station in this disclosure can also be rewritten as a terminal. For example, the embodiments of this disclosure can also be applied to a configuration where communication between a base station and a terminal is rewritten as communication between multiple terminals (e.g., D2D (Device-to-Device) or V2X (Vehicle-to-Everything)). In this case, the functions of the aforementioned base station 10 can also be set as the configuration of the terminal 20. Furthermore, terms such as "uplink" and "downlink" can also be rewritten as terms corresponding to inter-terminal communication (e.g., "side"). For example, terms such as uplink channel and downlink channel can also be rewritten as side channel.

[0318] Likewise, the terminal in the present disclosure may be rewritten as a base station. In this case, the functions of the terminal 20 described above may be replaced with the configuration of the base station 10.

[0324] The information service unit 2012 may include input devices for accepting input from the outside (e.g., keyboard, mouse, microphone, switch, button, sensor, touchpad, etc.), and may also include output devices for implementing output to the outside (e.g., display, speaker, LED light, touchpad, etc.).

[0325] The driving assistance system unit 2030 is composed of various devices that provide functions for preventing accidents or reducing the driver's driving burden, such as millimeter-wave radar, light detection and ranging (LiDAR), cameras, positioning sensors (e.g., GNSS, etc.), map information (e.g., high-definition (HD) maps, autonomous vehicle (AV) maps, etc.), gyroscope systems (e.g., inertial measurement units (IMUs), inertial navigation systems (INS), etc.), artificial intelligence (AI) chips, AI processors, and one or more ECUs that control these devices. In addition, the driving assistance system unit 2030 sends and receives various information via the communication module 2013 to implement driving assistance functions or autonomous driving functions.

[0326] The communication module 2013 can communicate with the microprocessor 2031 and other components of the vehicle 2001 via the communication port.

[0327] The communication module 2013 is controlled by the microprocessor 2031 of the electronic control unit 2010 and is a communication device capable of communicating with external devices. For example, various information can be transmitted and received with the external device via wireless communication.

[0331] <Meaning and Explanation of Terms>

[0332] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of operations. For example, "determining" and "judging" can include situations where judging, calculating, computing, processing, deriving, investigating, looking up (e.g., searching a table, database, or other data structure), and ascertaining are considered "determining." Furthermore, "determining" and "receiving" (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in a memory) are considered "determining." Furthermore, "determining" and "resolving" can include situations where selecting, choosing, establishing, and comparing are considered "determining." In other words, "determining" and "resolving" can include situations where certain operations are considered "determining." In addition, "judge (decide)" can also be rewritten as "assuming (assuming)", "expecting (expecting)", "considering (considering)", etc.

[0333] Terms such as "connected", "coupled", or all variations thereof refer to all direct or indirect connections or combinations between two or more elements, and can include situations where there are one or more intermediate elements between the two elements that are "connected" or "coupled" to each other. The combination or connection between elements can be physical, logical, or a combination thereof. For example, "connect" can also be rewritten as "access". When used in this disclosure, it is possible to consider using at least one of one or more wires, cables, and printed electrical connections, and as several non-limiting and non-inclusive examples, using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (both visible and invisible) region to "connect" or "couple" two elements to each other.

[0334] <Reference Signal>

[0335] The reference signal can also be abbreviated as RS (Reference Signal), and can also be called a pilot (Pilot) etc. according to the applied standard.

[0336] <Meaning of "based on">

[0337] In the present disclosure, the description of "based on" used herein, unless otherwise specified, does not mean "only based on". In other words, the description of "based on" means both "only based on" and "at least based on".

[0338] <"First", "Second">

[0339] Any reference to elements using the designations "first", "second", etc. used in this specification does not comprehensively limit the quantity or order of these elements. These designations can be used in this specification as a convenient method for distinguishing between two or more elements. Therefore, the reference to the first and second elements does not mean that only two elements can be adopted, or that the first element must take precedence over the second element in any form.

[0340] <"Unit">

[0341] The expression "section" in the structure of each of the above devices can also be rewritten as "unit", "circuit", "equipment", etc.

[0342] <Open form>

[0343] When using "include", "including", and their variants in the present disclosure, these terms, like the term "comprising", are inclusive. Further, the term "or" used in this specification or claims does not mean exclusive or.

[0344] <Time units such as TTI, frequency units such as RB, radio frame structure>

[0345] A radio frame can also be composed of one or more frames in the time domain. In the time domain, each of the one or more frames can also be called a subframe. A subframe can also be composed of one or more time slots in the time domain. A subframe can also be a fixed time length (e.g., 1 ms) independent of the numerology.

[0346] A parameter set may also be a communication parameter applied to at least one of the transmission and reception of a signal or channel. For example, a parameter set may include at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), the number of symbols per TTI, radio frame structure, specific filtering performed by the transmitter and receiver in the frequency domain, and specific windowing performed by the transmitter and receiver in the time domain.

[0347] A slot may also be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.) in the time domain. A slot may also be a time unit based on a parameter set.

[0348] A time slot may also contain multiple mini-slots. Each mini-slot may also consist of one or more symbols in the time domain. Furthermore, a mini-slot may also be referred to as a sub-slot. A mini-slot may also consist of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may also be referred to as PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using mini-slots may also be referred to as PDSCH (or PUSCH) mapping type B.

[0349] Any of radio frames, subframes, slots, mini-slots, and symbols represents a time unit for signal transmission. Radio frames, subframes, slots, mini-slots, and symbols may also be referred to by other names corresponding to each other.

[0350] For example, a subframe can also be called a Transmission Time Interval (TTI), multiple consecutive subframes can also be called a TTI, and a slot or a mini-slot can also be called a TTI. In other words, at least one of a subframe and a TTI can be a subframe (1ms) in existing LTE, a period shorter than 1ms (for example, 1 to 13 symbols), or a period longer than 1ms. Furthermore, the unit representing a TTI can be called a slot, a mini-slot, or something similar, rather than a subframe.

[0351] Here, TTI refers to the minimum time unit used for scheduling in wireless communications. For example, in the LTE system, a base station schedules each user terminal by allocating radio resources (such as the frequency bandwidth and transmit power available to each user terminal) in TTI units. The definition of TTI is not limited to this.

[0352] The TTI can be a unit of time for transmitting channel-coded data packets (transport blocks), code blocks, code words, etc., and can also be a unit of processing for scheduling, link adaptation, etc. Furthermore, when a TTI is given, the time interval (e.g., the number of symbols) to which the transport blocks, code blocks, code words, etc. are actually mapped can be shorter than the TTI.

[0353] Furthermore, when one slot or one minislot is referred to as a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) can also be the minimum time unit for scheduling. Furthermore, the number of slots (minislots) that constitute this minimum time unit for scheduling can also be controlled.

[0354] A TTI with a time length of 1 ms may also be referred to as a normal TTI (TTI in LTE Rel. 8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may also be referred to as a shortened TTI, a short TTI, a partial TTI (partial or fractional TTI), a shortened subframe, a short subframe, a minislot, a subslot, a time slot, etc.

[0355] In addition, long TTI (e.g., normal TTI, subframe, etc.) can also be rewritten as TTI with a time length greater than 1ms, and short TTI (e.g., shortened TTI, etc.) can also be rewritten as TTI with a TTI length smaller than the long TTI and greater than 1ms.

[0356] A resource block (RB) is a unit of resource allocation in the time and frequency domains. In the frequency domain, it may also include one or more consecutive subcarriers (subcarriers). The number of subcarriers contained in an RB can be the same regardless of the parameter set, for example, it can be 12 subcarriers. The number of subcarriers contained in an RB can also be determined based on the parameter set.

[0357] In addition, the time domain of an RB may also include one or more symbols, and may be the length of one slot, one mini-slot, one subframe, or one TTI. One TTI, one subframe, etc. may also be composed of one or more resource blocks.

[0358] In addition, one or more RBs may also be referred to as a physical resource block (PRB: Physical RB), a sub-carrier group (SCG: Sub-Carrier Group), a resource element group (REG: Resource Element Group), a PRB pair, an RB pair, etc.

[0359] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0360] A bandwidth part (BWP) (also known as a fractional bandwidth) can also represent a subset of contiguous common resource blocks (RBs) used for a particular parameter set within a carrier. Common RBs can be identified by their index relative to the common reference point of the carrier. PRBs can be defined by a BWP and numbered within that BWP.

[0361] The BWP may include a UL BWP (UL BWP) and a DL BWP (DL BWP). For a UE, one or more BWPs may be configured within one carrier.

[0362] At least one of the configured BWPs may be activated, and the UE may not assume that it will transmit or receive specific signals / channels outside of the activated BWP. In addition, "cell", "carrier", etc. in this disclosure may also be rewritten as "BWP".

[0363] The above-described structures of radio frames, subframes, slots, mini-slots, and symbols are merely examples. For example, various variations are possible, including the number of subframes within a radio frame, the number of slots per subframe or radio frame, the number of mini-slots within a slot, the number of symbols and RBs within a slot or mini-slot, the number of subcarriers within an RB, the number of symbols within a TTI, the symbol length, and the cyclic prefix (CP) length.

[0364] <Maximum Transmit Power>

[0365] The “maximum transmit power” described in the present disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated UE maximum transmit power).

[0366] <Article>

[0367] In the present disclosure, when an article is added by translation, such as in English, such as a, an, and the, the present disclosure also includes cases where the noun following the article is in plural form.

[0368] <“Different”>

[0369] In this disclosure, the term "A is different from B" may also mean "A and B are different from each other." It should be noted that the term may also mean "A and B are each different from C." Terms such as "separate" and "bound" may be interpreted similarly.
