Description

[Technical Field]

[0001] The present disclosure relates to a terminal and a communication method. [Background technology]

[0002] Long Term Evolution (LTE) has been specified for Universal Mobile Telecommunication System (UMTS) networks to achieve higher data rates and lower latency. Furthermore, successor systems to LTE are also being considered to achieve even greater bandwidth and speed than LTE. Examples of 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).

[0003] In 3GPP, in Rel. 17, methods called Ultra-Reliable and Low Latency Communications (URLLC) and Industrial Internet of Things (IIoT) were studied, and several technologies were approved (see, for example, Non-Patent Document 1). For example, in Rel. 17, based on the work in Rel. 16 (RAN1), technologies related to intra-terminal multiplexing of traffic with different priorities and intra-terminal prioritization were approved (specified).

[0004] For example, multiplexing operations between HARQ-ACK / SR / CSI and PUSCH for traffic with different priorities, including the case of UCI for PUCCH and UCI for PUSCH, have been identified.

[0005] Also, based on the solution considered in Rel. 16, PHY prioritization for overlapping dynamic grant PUSCH (DG PUSCH) and configured grant PUSCH (CG PUSCH) is specified. The DG PUSCH and CG PUSCH may have different PHY priorities in the BWP of the serving cell, and the serving cell may have related cancellation behavior for PUSCHs with lower physical priorities.

[0006] Note that RAN is an abbreviation for Radio Access Network. PUCCH is an abbreviation for Physical Uplink Control Channel. PUSCH is an abbreviation for Physical Uplink Shared Channel. UCI is an abbreviation for Uplink Control Information. HARQ-ACK is an abbreviation for Hybrid Automatic Repeat request - Acknowledgement. SR is an abbreviation for Scheduling Request. CSI is an abbreviation for Channel State Information. BWP is an abbreviation for Band Width Part. [Prior art documents] [Non-patent literature]

[0008] However, there has been insufficient consideration of terminal operation when repeating a first uplink signal having a first priority and for which uplink transmission is set and permitted, and a second uplink signal having a second priority lower than the first priority and for which uplink transmission is dynamically permitted, and further consideration is required.

[0009] One aspect of the present disclosure is to provide a terminal and a communication method that, when a first uplink signal having a first priority and for which uplink transmission is set and permitted, and a second uplink signal having a second priority lower than the first priority and for which uplink transmission is dynamically permitted, are repetitively transmitted, appropriately transmit the first uplink signal having a higher priority. [Means for solving the problem]

[0013] Hereinafter, an embodiment according to one aspect of the present disclosure will be described with reference to the drawings.

[0014] In 3GPP, schemes called URLLC and IIoT are being considered in Rel. 17. In 3GPP, the following agreement was reached on operations when a high priority (HP) CG PUSCH and a low priority (LP) DG PUSCH overlap (overlap in time).

[0015] <Agreement details> When the Media Access Control (MAC) of the terminal delivers two MAC PDUs to the physical (PHY), the PHY may prioritize them so that the terminal transmits the HP CG PUSCH and drops the LP DG PUSCH. The PHY may drop the LP DG PUSCH at the latest from the first symbol that overlaps with the HP CG PUSCH. Note that processing of the LP CG PUSCH symbols that do not overlap with the HP CG PUSCH may depend on the implementation (capability) of the terminal.

[0016] Fig. 1 is a diagram illustrating an example of the content of the agreement, in which HP CG and LP DG indicate the transmission timings of the HP CG PUSCH and the LP DG PUSCH.

[0017] When the HP CG PUSCH and the LP DG PUSCH overlap, the terminal may transmit the HP CG PUSCH and drop the LP DG PUSCH. For example, the terminal may drop the LP DG PUSCH by the timing indicated by arrow A1 in FIG. 1 at the latest.

[0018] The terminal may or may not drop symbols of the LP DG PUSCH that do not overlap with the HP CG PUSCH, i.e., the terminal may drop the entire LP DG PUSCH or a portion of it.

[0019] For example, in Fig. 1, the terminal may drop the entire LP DG PUSCH, or the terminal may not drop the LP DG PUSCH (the LP DG PUSCH that does not overlap with the HP CG PUSCH) before the timing indicated by arrow A1 in Fig. 1.

[0020] Dropping the DG PUSCH may be interpreted as not transmitting the DG PUSCH. Not dropping the DG PUSCH may be interpreted as transmitting the DG PUSCH. Dropping the CG PUSCH may be interpreted as not transmitting the CG PUSCH. Not dropping the CG PUSCH may be interpreted as transmitting the CG PUSCH.

[0021] The dropping may also be referred to as canceling. The overlapping may also be referred to as collision. The MAC may also be referred to as a MAC layer. The PHY may also be referred to as a PHY layer. The symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0022] The DG PUSCH may also be dynamically scheduled by physical layer signaling, such as Downlink Control Information (DCI), and may be referred to as a dynamic PUSCH.

[0023] In addition, in NR, Release 16 specifies the configuration of CG PUSCH (see, for example, 3GPP TS38.331 V16.2.0). CG PUSCH includes Type 1 CG PUSCH and Type 2 CG PUSCH. The CG PUSCH may be either Type 1 CG PUSCH or Type 2 CG PUSCH.

[0024] The transmission parameters of Type 1 CG PUSCH are provided by higher layer signaling such as "configuredGrantConfig", "pusch-Config", and "rrc-ConfiguredUplinkGrant". The activation and deactivation of Type 1 CG PUSCH depend on the RRC-configuration and do not depend on physical layer signaling such as DCI.

[0025] The transmission parameters of Type 2 CG PUSCH are provided by "configuredGrantConfig", "pusch-Config", and "activation DCI". Activation and deactivation of Type 2 CG PUSCH depend on the RRC-configuration and DCI. One DCI can activate one CG PUSCH and deactivate multiple CG PUSCHs.

[0026] As described above, 3GPP has agreed on the operation when the HP CG PUSCH and the LP DG PUSCH overlap. On the other hand, the operation when the LP CG PUSCH and the HP DG PUSCH overlap is under consideration. In 3GPP, the following discussion is taking place regarding the operation when the LP CG PUSCH and the HP DG PUSCH overlap.

[0027] <Discussion> The PHY layer may prioritize to assume that the terminal drops the HP DG PUSCH at the latest by the first symbol of the LP CG PUSCH that overlaps the HP DG PUSCH. The terminal may assume that the first symbol of the HP DG PUSCH or the first symbol that overlaps with the LP CG PUSCH is T after the last symbol of the Physical Downlink Control Channel (PDCCH) that schedules the HP DG PUSCH. proc,2It may be assumed that it is not before +d1.

[0028] In addition, T proc,2 is the time it takes for the terminal to prepare PUSCH data after receiving the UL grant, and d1 is the time determined based on various parameters such as values ​​reported from the terminal. Therefore, the terminal may assume that the first symbol of the HP DG PUSCH is not later than the time it takes for the terminal to prepare PUSCH data after the last symbol of the PDCCH scheduling the HP DG PUSCH.

[0029] Fig. 2 is a diagram for explaining an example of the content of the discussion, in which LP CG and HP DG indicate the transmission timings of the LP CG PUSCH and the HP DG PUSCH.

[0030] The terminal may drop the LP CG PUSCH at the latest by the first symbol where the LP CG PUSCH and the HP DG PUSCH overlap.

[0031] For example, as shown in FIG. 2, the terminal may determine whether the first symbol of the HP DG PUSCH is T after the last symbol of the PDCCH (DCI) that schedules the HP DG PUSCH. proc,2 +d1 after the last symbol of the PDCCH containing DCI. proc,2 LP CG PUSCHs that overlap with HP DG PUSCHs, assuming they are not earlier than +d1, may be dropped.

[0032] <Analysis> However, when both or one of the CG PUSCH and DG PUSCH, which have different priorities, is transmitted in a repetitive manner (see, for example, Section 6 of 3GPP TS38.331 V16.7.0), the terminal operation when the CG PUSCH and the DG PUSCH overlap has not been sufficiently considered.

[0033] Note that the following two cases may be assumed regarding the overlap between a CG PUSCH and a DG PUSCH with different priorities.

[0034] Case 1: HP CG PUSCH overlaps with LP DG PUSCH Case 2: LP CG PUSCH overlaps with HP DG PUSCH

[0035] In each of the above cases 1 and 2, the following cases may be assumed for repetition transmission of CG PUSCH and DG PUSCH: Note that hereinafter, repetition transmission may be simply referred to as repetition.

[0036] Case 1: In the overlap of HP CG PUSCH and LP DG PUSCH, Case 1-1: HP CG PUSCH is repeated, LP DG PUSCH is not repeated Case 1-2: HP CG PUSCH is not repeated, LP DG PUSCH is repeated Case 1-3: HP CG PUSCH and LP DG PUSCH are repeated

[0037] Case 2: In the overlap of LP CG PUSCH and HP DG PUSCH, Case 2-1: LP CG PUSCH is repeated, HP DG PUSCH is not repeated Case 2-2: LP CG PUSCH is not repeated, and HP DG PUSCH is repeated Case 2-3: LP CG PUSCH and HP DG PUSCH are repeated

[0038] Note that "no repetition" may be understood as a single transmission of the HP CG PUSCH or the LP CG PUSCH, and also as a single transmission of the LP DG PUSCH or the HP DG PUSCH.

[0039] The terminal operation in the above case will be explained below.

[0040] <Proposal 1> Proposal 1 describes the terminal operation when the HP CG PUSCH and the LP DG PUSCH overlap (analysis case 1). When the HP CG PUSCH and the LP DG PUSCH overlap, the terminal may drop the LP DG PUSCH, which has a lower priority than the HP CG PUSCH.

[0041] When the terminal MAC delivers two MAC PDUs to the PHY, the PHY may prioritize them so that the terminal assumes that it will transmit the HP CG PUSCH and drop the LP DG PUSCH at the latest from the first symbol that overlaps with the HP CG PUSCH.

[0042] Note that processing of symbols of the LP DG PUSCH that do not overlap with the HP CG PUSCH may depend on the implementation of the terminal. For example, when part of the LP DG PUSCH overlaps with the HP CG PUSCH, the terminal may or may not transmit symbols of the LP DG PUSCH that do not overlap with the HP CG PUSCH.

[0043] <Case 1-1> In case 1-1, the terminal operation when the HP CG PUSCH is repeated and the LP DG PUSCH is not repeated will be described.

[0044] When the terminal repeats the HP CG PUSCH and does not repeat the LP DG PUSCH (in the case of single transmission), the terminal may drop the LP DG PUSCH that overlaps the repeated HP CG PUSCH.

[0045] Figures 3 and 4 are diagrams illustrating an example of Case 1-1 of Proposal 1. HP CG and LP DG shown in Figure 4 indicate the transmission timing of the HP CG PUSCH and the LP DG PUSCH. Figure 4 shows two examples (Examples 1 and 2) of the transmission timing of the HP CG PUSCH and the LP DG PUSCH. As shown in Figure 4, in Case 1-1, the HP CG PUSCH is repeated and the LP DG PUSCH is transmitted as a single transmission.

[0046] Example 1 in Fig. 4 shows an example in which a single transmitted LP DG PUSCH overlaps with one of the repeated HP CG PUSCHs. As shown in Example 1 in Fig. 4, the terminal may drop the LP DG PUSCH that overlaps with the HP CG PUSCH in the second repetition.

[0047] Example 2 in Fig. 4 shows an example in which a single transmitted LP DG PUSCH overlaps with multiple HP CG PUSCHs among repeated HP CG PUSCHs. As shown in Example 2 in Fig. 4, the terminal may drop the LP DG PUSCHs that overlap with the HP CG PUSCHs in the first and second repetitions.

[0048] When repetition is included (when PUSCH repetition is performed), the terminal may schedule a CG PUSCH with a higher priority index (HP CG PUSCH) and a PUSCH with a lower priority index (LP DG PUSCH) scheduled by the DCI (format) in PDCCH reception so that they overlap in time. Then, when a lower priority LP DG PUSCH (transmission) overlaps in time with a higher priority HP CG PUSCH (transmission), the terminal may assume that the LP DG PUSCH is dropped before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH.

[0049] Through the above operations, the terminal can appropriately transmit the HP CG PUSCH with high priority when the HP CG PUSCH is repeated but the LP DG PUSCH is not repeated and the HP CG PUSCH and the LP DG PUSCH overlap.

[0050] Each of the multiple repeated HP CG PUSCHs may be transmitted using one slot or one sub-slot. For example, one HP CG PUSCH shown in Fig. 4 may be transmitted using one slot or one sub-slot. The same applies when the LP DG PUSCH, the LP CG PUSCH, and the HP DG PUSCH are repeated.

[0051] Furthermore, multiple HP CG PUSCHs to be repeated may be transmitted using one slot or one sub-slot. For example, the four HP CG PUSCHs shown in Fig. 4 may be transmitted using one slot or one sub-slot. When multiple HP CG PUSCHs to be repeated are transmitted using one slot or one sub-slot, the HARQ-ACK process IDs for each of the multiple HP CG PUSCHs may be different. The same applies when an LP DG PUSCH, an LP CG PUSCH, and an HP DG PUSCH are repeated.

[0052] <Case 1-2> In case 1-2, the terminal operation when the HP CG PUSCH is not repeated and the LP DG PUSCH is repeated will be described.

[0053] When the terminal does not repeat (single-transmits) the HP CG PUSCH and repeats the LP DG PUSCH, the terminal may drop the LP DG PUSCH that overlaps with the HP CG PUSCH (see option 1 below).

[0054] When the terminal transmits a single HP CG PUSCH and repeats an LP DG PUSCH, the terminal may drop the LP DG PUSCH that overlaps with the HP CG PUSCH, and may also drop the LP DG PUSCH that does not overlap with the HP CG PUSCH (see options 2 and 3 below).

[0055] Figures 5 and 6 are diagrams illustrating an example of Case 1-2 of Proposal 1. HP CG and LP DG shown in Figure 6 indicate the transmission timing of the HP CG PUSCH and the LP DG PUSCH. Figure 6 also shows examples of the transmission timing of the HP CG PUSCH and the LP DG PUSCH in Options 1, 2, and 3 described below. As shown in Figure 6, in Case 1-2, the HP CG PUSCH is transmitted as a single transmission, and the LP DG PUSCH is repeated.

[0056] <Option 1> The terminal may drop LP DG PUSCHs that overlap with HP CG PUSCHs and may not drop LP DG PUSCHs that do not overlap with HP CG PUSCHs. In other words, the terminal may drop only LP DG PUSCHs that overlap with HP CG PUSCHs and transmit the remaining LP DG PUSCHs (LP DG PUSCHs that do not overlap with HP CG PUSCHs).

[0057] For example, as shown in Option 1 of Fig. 6, the terminal may drop the second LP DG PUSCH that overlaps with the HP CG PUSCH among the LP DG PUSCHs that are repeated four times, and the terminal may not drop the first, third, and fourth LP DG PUSCHs that do not overlap with the HP CG PUSCH.

[0058] When repetition is included, the terminal may schedule an HP CG PUSCH with a higher priority index to overlap in time with an LP DG PUSCH with a lower priority index scheduled by the DCI (format) in PDCCH reception. Then, when a low-priority repetition LP DG PUSCH overlaps in time with a high-priority single-transmission HP CG PUSCH, the terminal may assume that the LP DG PUSCH is dropped before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH.

[0059] Through the above operations, when the terminal does not repeat the HP CG PUSCH but repeats the LP DG PUSCH and the HP CG PUSCH and the LP DG PUSCH overlap, the terminal can appropriately transmit the HP CG PUSCH with high priority.

[0060] Note that, when multiple LP DG PUSCHs overlap one HP CG PUSCH, the terminal may drop the multiple LP DG PUSCHs that overlap one HP CG PUSCH.

[0061] <Option 2> The terminal may drop the LP DG PUSCHs to be repeated, except for the LP DG PUSCHs that do not overlap with the HP CG PUSCH and that precede the symbol that first overlaps with the HP CG PUSCH. In other words, the terminal may drop the LP DG PUSCHs that overlap with the HP CG PUSCH, and drop the LP DG PUSCHs that follow the dropped LP DG PUSCH.

[0062] For example, the terminal may drop the second LP DG PUSCH that overlaps with the HP CG PUSCH among the LP DG PUSCHs repeated four times as shown in Option 2 of Fig. 6. Then, the terminal may drop the third and fourth LP DG PUSCHs that follow the dropped LP DG PUSCH (second LP DG PUSCH).

[0063] When repetition is included, the terminal may schedule an HP CG PUSCH with a higher priority index to overlap in time with an LP DG PUSCH with a lower priority index scheduled by the DCI (format) in PDCCH reception. If a low-priority repetition LP DG PUSCH overlaps in time with a high-priority single-transmission HP CG PUSCH, the terminal may assume that the LP DG PUSCH is dropped before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH. The terminal may also drop the LP DG PUSCH that follows the dropped LP DG PUSCH.

[0064] Through the above operations, when the terminal does not repeat the HP CG PUSCH but repeats the LP DG PUSCH and the HP CG PUSCH overlaps, the terminal can appropriately transmit the HP CG PUSCH with high priority. Furthermore, the terminal drops the LP DG PUSCH that overlaps with the HP CG PUSCH, and also drops the LP DG PUSCH that follows the dropped LP DG PUSCH. Through this operation, the terminal can reduce power consumption.

[0065] In the above description, the terminal drops the LP DG PUSCH that overlaps with the HP CG PUSCH and the LP DG PUSCH that follows the LP DG PUSCH that overlaps with the HP CG PUSCH, but this is not limited to this. The terminal may also drop the LP DG PUSCH that overlaps with the HP CG PUSCH and the LP DG PUSCH before it overlaps with the HP CG PUSCH. For example, in Option 2 of FIG. 6, the terminal may drop the first and second LP DG PUSCHs but not the third and fourth LP DG PUSCHs.

[0066] <Option 3> The terminal may also drop LP DG PUSCHs that are repeated and that precede the symbol that first overlaps with a non-repeated HP CG PUSCH and do not overlap with the HP CG PUSCH. That is, the terminal may drop LP DG PUSCHs that overlap with the HP CG PUSCH and also drop the remaining LP DG PUSCHs that do not overlap with the HP CG PUSCH. In other words, the terminal may drop all repeated LP DG PUSCHs.

[0067] For example, as shown in Option 3 of Fig. 6, the terminal may drop the second LP DG PUSCH that overlaps with the HP CG PUSCH among the LP DG PUSCHs that are repeated four times. The terminal may also drop the remaining LP DG PUSCHs that do not overlap with the HP CG PUSCH (the first, third, and fourth LP DG PUSCHs). That is, when the single-transmission HP CG PUSCH and the repeated LP DG PUSCHs overlap, the terminal may drop all of the repeated LP DG PUSCHs.

[0068] When repetition is included, the terminal may schedule an HP CG PUSCH with a higher priority index to overlap in time with an LP DG PUSCH with a lower priority index scheduled by the DCI (format) in PDCCH reception. Then, when a low-priority repetition LP DG PUSCH overlaps in time with a high-priority single-transmission HP CG PUSCH, the terminal may assume that it drops all of the repetition LP DG PUSCHs before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH.

[0069] Through the above operations, when the terminal does not repeat the HP CG PUSCH but repeats the LP DG PUSCH and the HP CG PUSCH overlaps, the terminal can appropriately transmit the HP CG PUSCH with high priority. Furthermore, the terminal drops the LP DG PUSCH that overlaps with the HP CG PUSCH, and also drops the remaining LP DG PUSCH that does not overlap with the HP CG PUSCH. Through this operation, the terminal can reduce power consumption.

[0070] <Cases 1-3> In Cases 1-3, the terminal operation when the HP CG PUSCH and the LP DG PUSCH are repeated will be described.

[0071] When repeating the HP CG PUSCH and the LP DG PUSCH, the terminal may drop the LP DG PUSCH that overlaps with the HP CG PUSCH, but may not drop the LP DG PUSCH that does not overlap with the HP CG PUSCH (see option 1 below).

[0072] When repeating the HP CG PUSCH and the LP DG PUSCH, the terminal may drop the LP DG PUSCH that overlaps with the HP CG PUSCH, and may also drop the LP DG PUSCH that does not overlap with the HP CG PUSCH (see options 2 and 3 below).

[0073] Figures 7 and 8 are diagrams illustrating examples of cases 1-3 of Proposal 1. HP CG and LP DG shown in Figure 8 indicate the transmission timing of the HP CG PUSCH and the LP DG PUSCH. Figure 8 also shows examples of the transmission timing of the HP CG PUSCH and the LP DG PUSCH in Options 1, 2, and 3 described below. As shown in Figure 8, in Cases 1-3, the HP CG PUSCH and the LP DG PUSCH are repeated.

[0074] <Option 1> The terminal may drop the LP DG PUSCH that overlaps with the HP CG PUSCH, and may not drop the LP DG PUSCH that does not overlap with the HP CG PUSCH.

[0075] For example, as shown in Option 1 of Fig. 8, the terminal may drop the second and third LP DG PUSCHs that overlap with the HP CG PUSCH among the LP DG PUSCHs that are repeated four times, and the terminal may not drop the first and fourth LP DG PUSCHs that do not overlap with the HP CG PUSCH.

[0076] When repetition is included, the terminal may schedule an HP CG PUSCH with a higher priority index to overlap in time with an LP DG PUSCH with a lower priority index scheduled by the DCI (format) in PDCCH reception. Then, when a low-priority repetition LP DG PUSCH overlaps in time with a high-priority repetition HP CG PUSCH, the terminal may assume that the LP DG PUSCH is dropped before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH.

[0077] Through the above operations, when the terminal repeats the HP CG PUSCH and the LP DG PUSCH and the HP CG PUSCH overlaps with the LP DG PUSCH, the terminal can appropriately transmit the HP CG PUSCH with high priority.

[0078] <Option 2> The terminal may drop the repeated LP DG PUSCHs except for the LP DG PUSCHs that do not overlap with the HP CG PUSCH and that precede the symbol that first overlaps with the repeated HP CG PUSCH. In other words, the terminal may drop the LP DG PUSCHs that overlap with the HP CG PUSCH and drop the LP DG PUSCHs that follow the dropped LP DG PUSCH.

[0079] For example, the terminal may drop the second and third LP DG PUSCHs that overlap with the HP CG PUSCH among the LP DG PUSCHs that are repeated four times as shown in Option 2 of Fig. 8. Then, the terminal may drop the fourth LP DG PUSCH that follows the dropped LP DG PUSCHs (the second and third LP DG PUSCHs).

[0080] When repetition is included, the terminal may schedule an HP CG PUSCH with a higher priority index and an LP DG PUSCH with a lower priority index scheduled by the DCI (format) in PDCCH reception so that they overlap in time. Then, when a low-priority repetition LP DG PUSCH overlaps in time with a high-priority repetition HP CG PUSCH, the terminal may assume that the LP DG PUSCH will be dropped before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH. The terminal may also drop the LP DG PUSCH that follows the dropped LP DG PUSCH.

[0081] Through the above operations, when the terminal repeats the HP CG PUSCH and the LP DG PUSCH and the HP CG PUSCH overlaps with the LP DG PUSCH, the terminal can appropriately transmit the HP CG PUSCH with high priority. Furthermore, the terminal drops the LP DG PUSCH that overlaps with the HP CG PUSCH, and also drops the LP DG PUSCH that follows the dropped LP DG PUSCH. Through this operation, the terminal can reduce power consumption.

[0082] In the above description, the terminal drops the LP DG PUSCH that overlaps with the HP CG PUSCH and the LP DG PUSCH that follows the LP DG PUSCH that overlaps with the HP CG PUSCH, but this is not limited to this. The terminal may also drop the LP DG PUSCH that overlaps with the HP CG PUSCH and the LP DG PUSCH that precedes the overlap with the HP CG PUSCH. For example, in Option 2 of FIG. 8, the terminal may drop the first, second, and third LP DG PUSCHs but not the fourth LP DG PUSCH.

[0083] <Option 3> The terminal may also drop LP DG PUSCHs to be repeated that are before the symbol that first overlaps with the HP CG PUSCH and do not overlap with the HP CG PUSCH. That is, the terminal may drop LP DG PUSCHs that overlap with the HP CG PUSCH and also drop the remaining LP DG PUSCHs that do not overlap with the HP CG PUSCH. In other words, the terminal may drop all LP DG PUSCHs to be repeated.

[0084] For example, the terminal may drop the second and third LP DG PUSCHs that overlap with the HP CG PUSCH among the LP DG PUSCHs that are repeated four times as shown in Option 3 of Fig. 8. The terminal may also drop the remaining LP DG PUSCHs that do not overlap with the HP CG PUSCH (the first and fourth LP DG PUSCHs).

[0085] When repetition is included, the terminal may schedule an HP CG PUSCH with a higher priority index so that it overlaps in time with an LP DG PUSCH with a lower priority index scheduled by the DCI (format) in PDCCH reception. Then, when a low-priority repetition LP DG PUSCH overlaps in time with a high-priority repetition HP CG PUSCH, the terminal may assume that it drops all of the LP DG PUSCH before the first symbol of the LP DG PUSCH that overlaps with the HP CG PUSCH.

[0086] Through the above operations, when the terminal repeats the HP CG PUSCH and the LP DG PUSCH and the HP CG PUSCH overlaps with the LP DG PUSCH, the terminal can appropriately transmit the HP CG PUSCH with high priority. Furthermore, the terminal drops the LP DG PUSCH that overlaps with the HP CG PUSCH, and also drops the remaining LP DG PUSCH that does not overlap with the HP CG PUSCH. Through this operation, the terminal can reduce power consumption.

[0087] <Proposal 2> Proposal 2 describes the terminal operation when the LP CG PUSCH and the HP DG PUSCH overlap (analysis case 2). When the LP CG PUSCH and the HP DG PUSCH overlap, the terminal may drop the LP CG PUSCH, which has a lower priority than the HP DG PUSCH.

[0088] When the MAC of the terminal delivers two MAC PDUs to the PHY, the PHY may prioritize them so that the terminal assumes that it will drop the LP CG PUSCH from the first symbol that overlaps with the HP DG PUSCH at the latest. The terminal may determine if the first symbol of the HP DG PUSCH or the first symbol that overlaps with the LP CG PUSCH is T after the last symbol of the PDCCH scheduling the HP DG PUSCH. proc,2 It may be assumed that it is not before +d1.

[0089] In addition, T proc,2 +d1 may be added to or replaced by another time parameter, e.g., T proc,2 A time parameter determined based on various parameters such as a value reported from the terminal and / or a subcarrier spacing may be added, such as +d1+d2.

[0090] Note that processing of LP CG PUSCH symbols that do not overlap with the HP DG PUSCH may depend on the implementation of the terminal. For example, when a portion of the LP CG PUSCH overlaps with the HP DG PUSCH, the terminal may or may not transmit the LP CG PUSCH symbols that do not overlap with the HP DG PUSCH.

[0091] <Case 2-1> In case 2-1, the terminal operation when the LP CG PUSCH is repeated and the HP DG PUSCH is not repeated will be described.

[0092] If the terminal repeats the LP CG PUSCH but does not repeat the HP DG PUSCH (single transmission), the terminal may drop the LP CG PUSCH that overlaps the single-transmission HP DG PUSCH (see option 1 below).

[0093] When the terminal repeats the LP CG PUSCH and transmits a single HP DG PUSCH, it may drop the LP CG PUSCH that overlaps with the HP DG PUSCH and may also drop the LP CG PUSCH that does not overlap with the HP DG PUSCH (see options 2 and 3 below).

[0094] Figures 9 and 10 are diagrams illustrating an example of Case 2-1 of Proposal 2. LP CG and HP DG shown in Figure 10 indicate the transmission timing of the LP CG PUSCH and HP DG PUSCH. Figure 10 also shows examples of the transmission timing of the LP CG PUSCH and HP DG PUSCH in Options 1, 2, and 3 described below. As shown in Figure 10, in Case 2-1, the LP CG PUSCH is repeated and the HP DG PUSCH is transmitted as a single PUSCH.

[0095] <Option 1> The terminal may drop the LP CG PUSCH that overlaps with the HP DG PUSCH, but may not drop the LP CG PUSCH that does not overlap with the HP DG PUSCH. In other words, the terminal may drop only the LP CG PUSCH that overlaps with the HP DG PUSCH, and transmit the remaining LP CG PUSCH (the LP CG PUSCH that does not overlap with the HP DG PUSCH).

[0096] For example, as shown in Option 1 of Fig. 10, the terminal may drop the second and third LP CG PUSCHs that overlap with the HP DG PUSCH among the LP CG PUSCHs that are repeated four times. The terminal may not drop the first and fourth LP CG PUSCHs that do not overlap with the HP DG PUSCH. Here, the terminal may check whether the first symbol of the HP DG PUSCH is T after the last symbol of the PDCCH (DCI) that schedules the HP DG PUSCH. proc,2 It may be assumed that it is not before +d1.

[0097] When repetition is included, the terminal may schedule a CG PUSCH with a lower priority index (LP CG PUSCH) and a DG PUSCH with a higher priority index (HP DG PUSCH) scheduled by the DCI (format) in PDCCH reception so that they overlap in time. Then, when a low-priority repetition LP CG PUSCH overlaps in time with a high-priority single-transmission HP DG PUSCH, the terminal may assume that the LP CG PUSCH is dropped before the first symbol of the LP CG PUSCH that overlaps with the HP DG PUSCH. Here, the terminal may assume that the first symbol where the single PUSCH transmission with a higher priority index (single-transmission HP DG PUSCH) and the repetition PUSCH transmission with a lower priority index (repetition LP CG PUSCH) overlap is T after the last symbol of the corresponding PDCCH reception. proc,2 You can assume that it won't start before +d1.

[0098] Through the above operations, when the terminal does not repeat the HP DG PUSCH but repeats the LP CG PUSCH, and when the HP DG PUSCH and the LP CG PUSCH overlap, the terminal can appropriately transmit the HP DG PUSCH with high priority.

[0099] <Option 2> The terminal may drop the repeated LP CG PUSCHs except for the LP CG PUSCHs that do not overlap with the HP DG PUSCH and that precede the symbol that first overlaps with the HP DG PUSCH. In other words, the terminal may drop the LP CG PUSCH that overlaps with the HP DG PUSCH and drop the LP CG PUSCHs that follow the dropped LP CG PUSCH.

[0100] For example, the terminal may drop the second LP CG PUSCH that overlaps with the HP DG PUSCH among the LP CG PUSCHs that are repeated four times as shown in Option 2 of Fig. 10. Then, the terminal may drop the third and fourth LP CG PUSCHs that follow the dropped LP CG PUSCH (second LP CG PUSCH).

[0101] When repetition is included, the terminal may schedule an LP CG PUSCH with a lower priority index and an HP DG PUSCH with a higher priority index scheduled by the DCI (format) in PDCCH reception so that they overlap in time. Then, when a low-priority repetition LP CG PUSCH overlaps in time with a high-priority single-transmission HP DG PUSCH, the terminal may assume that the LP CG PUSCH is dropped before the first symbol of the LP CG PUSCH that overlaps with the HP DG PUSCH. The terminal may also drop the LP CG PUSCH that follows the dropped LP CG PUSCH. Here, the terminal assumes that the first symbol where a single PUSCH transmission with a higher priority index (single-transmission HP DG PUSCH) and a repetition PUSCH transmission with a lower priority index (repetition LP CG PUSCH) overlap is T after the last symbol of the corresponding PDCCH reception. proc,2 You can assume that it won't start before +d1.

[0102] Through the above operations, when the terminal does not repeat the HP DG PUSCH but repeats the LP CG PUSCH and the HP DG PUSCH and the LP CG PUSCH overlap, the terminal can appropriately transmit the HP DG PUSCH with high priority. Furthermore, the terminal drops the LP CG PUSCH that overlaps with the HP DG PUSCH, and also drops the LP CG PUSCH that follows the dropped LP CG PUSCH. Through this operation, the terminal can reduce power consumption.

[0103] In the above description, the terminal drops the LP CG PUSCH that overlaps with the HP DG PUSCH and the LP CG PUSCH following the LP CG PUSCH that overlaps with the HP DG PUSCH, but this is not limited to this. The terminal may also drop the LP CG PUSCH that overlaps with the HP DG PUSCH and the LP CG PUSCH before it overlaps with the HP DG PUSCH. For example, in Option 2 of FIG. 10, the terminal may drop the first and second LP CG PUSCHs but not the third and fourth LP CG PUSCHs.

[0104] <Option 3> The terminal may also drop LP CG PUSCHs that are repeated before the symbol that first overlaps with the HP DG PUSCH and do not overlap with the HP DG PUSCH. That is, the terminal may drop LP CG PUSCHs that overlap with the HP DG PUSCH and also drop the remaining LP CG PUSCHs that do not overlap with the HP DG PUSCH. In other words, the terminal may drop all LP CG PUSCHs that are repeated.

[0105] For example, as shown in Option 3 of Fig. 10, the terminal may drop the second LP CG PUSCH that overlaps with the HP DG PUSCH among the LP CG PUSCHs that are repeated four times. The terminal may also drop the remaining LP CG PUSCHs that do not overlap with the HP DG PUSCH (the first, third, and fourth LP CG PUSCHs). That is, when a single-transmission HP DG PUSCH overlaps with a repeated LP CG PUSCH, the terminal may drop all of the repeated LP CG PUSCHs.

[0106] When repetition is included, the terminal may schedule an LP CG PUSCH with a lower priority index to overlap in time with an HP DG PUSCH with a higher priority index scheduled by the DCI (format) in PDCCH reception. Then, when a low-priority repetition LP CG PUSCH overlaps in time with a high-priority single-transmission HP DG PUSCH, the terminal may assume that it drops all of the repetition LP CG PUSCHs before the first symbol of the first repetition of the LP CG PUSCH that overlaps with the HP DG PUSCH.

[0107] Here, the terminal determines whether the first symbol where the single PUSCH transmission of a high priority index (single transmission HP DG PUSCH) and the repetition PUSCH transmission of a low priority index (repetition LP CG PUSCH) overlap is T proc,2 Alternatively, the terminal may assume that the first symbol of a repetition PUSCH transmission (repetition LP CG PUSCH) of a lower priority index that overlaps with a single PUSCH transmission (single transmission HP DG PUSCH) of a higher priority index does not start before T proc,2 You can assume that it won't start before +d1.

[0108] Through the above operations, when the terminal does not repeat the HP DG PUSCH but repeats the LP CG PUSCH and the HP DG PUSCH overlaps, the terminal can appropriately transmit the HP DG PUSCH with high priority. Furthermore, the terminal drops the LP CG PUSCH that overlaps with the HP DG PUSCH, and also drops the remaining LP CG PUSCH that does not overlap with the HP DG PUSCH. Through this operation, the terminal can reduce power consumption.

[0109] <Case 2-2> In case 2-2, the terminal operation when the HP DG PUSCH is repeated and the LP CG PUSCH is not repeated will be described.

[0110] When the terminal repeats the HP DG PUSCH and does not repeat the LP CG PUSCH (single transmission), the terminal may drop the LP CG PUSCH that overlaps the repeated HP DG PUSCH.

[0111] 11 and 12 are diagrams illustrating an example of Case 2-2 of Proposal 2. LP CG and HP DG shown in Fig. 12 indicate the transmission timing of the LP CG PUSCH and the HP DG PUSCH. As shown in Fig. 12, in Case 2-2, the HP DG PUSCH is repeated, and the LP CG PUSCH is transmitted as a single PUSCH.

[0112] For example, as shown in FIG. 12, the terminal may drop the single-transmission LP CG PUSCH that overlaps with the first HP DG PUSCH among the HP DG PUSCHs that are repeated twice.

[0113] When repetition is included, the terminal may schedule an LP CG PUSCH with a lower priority index and an HP DG PUSCH with a higher priority index scheduled by the DCI (format) in PDCCH reception so that they overlap in time. The terminal may then assume that, when a low-priority single-transmission LP CG PUSCH overlaps in time with a high-priority repetition HP DG PUSCH, the terminal drops the LP CG PUSCH before the first symbol of the LP CG PUSCH that overlaps with the HP DG PUSCH. Here, the terminal may assume that the first symbol where a repetition PUSCH transmission with a higher priority index (repetition HP DG PUSCH) and a single PUSCH transmission with a lower priority index (single-transmission LP CG PUSCH) overlap is within the range of T after the last symbol of the corresponding PDCCH reception. proc,2 You can assume that it won't start before +d1.

[0114] Through the above operations, the terminal can appropriately transmit the HP DG PUSCH with high priority when the HP DG PUSCH is repeated but the LP CG PUSCH is not repeated and the HP DG PUSCH and the LP CG PUSCH overlap.

[0115] <Case 2-3> In case 2-3, the terminal operation when the HP DG PUSCH and the LP CG PUSCH are repeated will be described.

[0116] When repeating the HP DG PUSCH and the LP CG PUSCH, the UE may drop the LP CG PUSCH that overlaps with the HP DG PUSCH, but may not drop the LP CG PUSCH that does not overlap with the HP DG PUSCH (see option 1 below).

[0117] When repeating an HP DG PUSCH and an LP CG PUSCH, the terminal may drop the LP CG PUSCH that overlaps with the HP DG PUSCH, and may also drop the LP CG PUSCH that does not overlap with the HP DG PUSCH (see options 2 and 3 below).

[0118] Figures 13 and 14 are diagrams illustrating an example of Case 2-3 of Proposal 2. HP DG and LP CG shown in Figure 14 indicate the transmission timing of the HP DG PUSCH and the LP CG PUSCH. Figure 14 also shows examples of the transmission timing of the HP DG PUSCH and the LP CG PUSCH in Options 1, 2, and 3 described below. As shown in Figure 14, in Case 2-3, the HP DG PUSCH and the LP CG PUSCH are repeated.

[0119] <Option 1> The terminal may drop the LP CG PUSCH that overlaps with the HP DG PUSCH, and may not drop the LP CG PUSCH that does not overlap with the HP DG PUSCH.

[0120] For example, as shown in Option 1 of Fig. 14, the terminal may drop the second and third LP CG PUSCHs that overlap with the HP DG PUSCH among the LP CG PUSCHs that are repeated four times, and the terminal may not drop the first and fourth LP CG PUSCHs that do not overlap with the HP DG PUSCH.

[0121] When repetition is included, the terminal may schedule the LP CG PUSCH with a lower priority index to overlap in time with the HP DG PUSCH with a higher priority index scheduled by the DCI (format) in PDCCH reception. Then, when the low-priority repetition LP CG PUSCH overlaps in time with the high-priority repetition HP DG PUSCH, the terminal may assume that the LP CG PUSCH is dropped before the first symbol of the LP CG PUSCH that overlaps with the HP DG PUSCH. Here, the terminal assumes that the first symbol where the repetition PUSCH transmission with a higher priority index (repetition HP DG PUSCH) and the repetition PUSCH transmission with a lower priority index (repetition LP CG PUSCH) overlap is T after the last symbol of the corresponding PDCCH reception. proc,2 You can assume that it won't start before +d1.

[0122] Through the above operations, when the terminal repeats the HP DG PUSCH and the LP CG PUSCH and the HP DG PUSCH overlaps with the LP CG PUSCH, the terminal can appropriately transmit the HP DG PUSCH with high priority.

[0123] <Option 2> The terminal may drop the repeated LP CG PUSCHs except for the LP CG PUSCHs that do not overlap with the HP DG PUSCH and that precede the symbol that first overlaps with the repeated HP DG PUSCH. In other words, the terminal may drop the LP CG PUSCHs that overlap with the HP DG PUSCHs and drop the LP CG PUSCHs that follow the dropped LP CG PUSCHs.

[0124] For example, the terminal may drop the second and third LP CG PUSCHs that overlap with the HP DG PUSCH among the LP CG PUSCHs that are repeated four times as shown in Option 2 of Fig. 14. Then, the terminal may drop the fourth LP CG PUSCH that follows the dropped LP CG PUSCHs (the second and third LP CG PUSCHs).

[0125] When repetition is included, the terminal may schedule an LP CG PUSCH with a lower priority index and an HP DG PUSCH with a higher priority index scheduled by the DCI (format) in PDCCH reception so that they overlap in time. Then, when a low-priority repetition LP CG PUSCH overlaps in time with a high-priority repetition HP DG PUSCH, the terminal may assume that the LP CG PUSCH is dropped before the first symbol of the LP CG PUSCH that overlaps with the HP DG PUSCH. The terminal may also drop the LP CG PUSCH that follows the dropped LP CG PUSCH. Here, the terminal assumes that the first symbol where a repetition PUSCH transmission with a higher priority index (repetition HP DG PUSCH) and a repetition PUSCH transmission with a lower priority index (repetition LP CG PUSCH) overlap is within the T after the last symbol of the corresponding PDCCH reception. proc,2 You can assume that it won't start before +d1.

[0126] Through the above operations, when the terminal repeats the HP DG PUSCH and the LP CG PUSCH and the HP DG PUSCH overlaps with the LP CG PUSCH, the terminal can appropriately transmit the HP DG PUSCH with higher priority. Furthermore, the terminal drops the LP CG PUSCH that overlaps with the HP DG PUSCH, and also drops the LP CG PUSCH that follows the dropped LP CG PUSCH. Through this operation, the terminal can reduce power consumption.

[0127] In the above description, the terminal drops the LP CG PUSCH that overlaps with the HP DG PUSCH and the LP CG PUSCH following the LP CG PUSCH that overlaps with the HP DG PUSCH, but this is not limited to this. The terminal may also drop the LP CG PUSCH that overlaps with the HP DG PUSCH and the LP CG PUSCH before it overlaps with the HP DG PUSCH. For example, in Option 2 of FIG. 14, the terminal may drop the first, second, and third LP CG PUSCHs but not the fourth LP CG PUSCH.

[0128] <Option 3> The terminal may also drop LP CG PUSCHs to be repeated that are before the symbol that first overlaps with the HP DG PUSCH and do not overlap with the HP DG PUSCH. That is, the terminal may drop LP CG PUSCHs that overlap with the HP DG PUSCH and also drop the remaining LP CG PUSCHs that do not overlap with the HP DG PUSCH. In other words, the terminal may drop all LP CG PUSCHs to be repeated.

[0129] For example, the terminal may drop the second and third LP CG PUSCHs that overlap with the HP DG PUSCH among the LP CG PUSCHs that are repeated four times as shown in Option 3 of Fig. 14. The terminal may also drop the remaining LP CG PUSCHs that do not overlap with the HP DG PUSCH (the first and fourth LP CG PUSCHs).

[0130] When repetition is included, the terminal may schedule the LP CG PUSCH of a lower priority index to overlap in time with the HP DG PUSCH of a higher priority index scheduled by the DCI (format) in PDCCH reception. Then, when the low-priority repetition LP CG PUSCH overlaps in time with the high-priority repetition HP DG PUSCH, the terminal may assume that it drops all of the LP CG PUSCH before the first symbol of the LP CG PUSCH that overlaps with the HP DG PUSCH. Here, the terminal assumes that the first symbol of the PUSCH transmission (LP CG PUSCH) of a lower priority index that overlaps with the PUSCH transmission (HP DG PUSCH) of a higher priority index is T after the last symbol of the corresponding PDCCH reception. proc,2 You can assume that it won't start before +d1.

[0131] Through the above operations, when the terminal repeats the HP DG PUSCH and the LP CG PUSCH and the HP DG PUSCH overlaps with the LP CG PUSCH, the terminal can appropriately transmit the HP DG PUSCH with high priority. Furthermore, the terminal drops the LP CG PUSCH that overlaps with the HP DG PUSCH, and also drops the remaining LP CG PUSCH that does not overlap with the HP DG PUSCH. Through this operation, the terminal can reduce power consumption.

[0132] The terminal determines whether the first symbol of the LP CG PUSCH is T after the last symbol of the DCI (PDCCH) that schedules the HP DG PUSCH. proc,2 For example, as shown in Option 3 of FIG. 14, the terminal may assume that the first symbol of the LP CG PUSCH to be repeated is T + d1 after the last symbol of the PDCCH to schedule the HP DG PUSCH. proc,2+d1. The above operations may also be applied to options 1, 2, and 3 in case 2-1, options 1 and 2 in case 2-2, and options 1 and 2 in case 2-3.

[0133] 14, the terminal may select the first symbol of the HP DG PUSCH after the last symbol of the PDCCH for scheduling the HP DG PUSCH. proc,2 It may be assumed that it is not before +d1.

[0134] In addition, the terminal determines whether the first symbol of the HP DG PUSCH or the LP CG PUSCH is T after the last symbol of the PDCCH that schedules the HP DG PUSCH. proc,2 +d1. Also, the terminal may assume that the first symbol of the HP CG PUSCH and the LP DG PUSCH is not before T proc,2 It may be assumed that it is not before +d1.

[0135] <Other 1> A terminal may be configured with multiple CG PUSCHs, and the multiple CG PUSCHs may have different priorities.

[0136] For example, a first CG PUSCH and a second CG PUSCH are configured in a terminal. The first CG PUSCH is an HP CG PUSCH, and the second CG PUSCH is an LP CG PUSCH. Repetition is applied to both or one of the first CG PUSCH and the second CG PUSCH.

[0137] In the above conditions, if the first CG PUSCH and the second CG PUSCH overlap, the terminal may drop the second CG PUSCH with lower priority (LP CG PUSCH) according to the operations described in Proposal 1 and / or Proposal 2.

[0138] <Other 2> A Type 1 CG PUSCH and a Type 2 CG PUSCH may be configured in the terminal. The Type 1 CG PUSCH and the Type 2 CG PUSCH may have different priorities.

[0139] For example, let Type 1 CG PUSCH be HP CG PUSCH and Type 2 CG PUSCH be LP CG PUSCH. It is assumed that repetition is applied to both or one of Type 1 CG PUSCH and Type 2 CG PUSCH.

[0140] Under the above conditions, if a Type 1 CG PUSCH and a Type 2 CG PUSCH overlap, the terminal may drop the low-priority Type 2 CG PUSCH (LP CG PUSCH) in accordance with the operations described in Proposal 1 and / or Proposal 2.

[0141] <Variations> Which of the multiple proposals and / or which of the multiple options is applied may be determined in the following manner.

[0142] - Set by upper layer parameters. · The UE reports it as UE capability(ies). -It is stated in the specifications. Determined based on higher layer parameter settings and reported UE capability. · Determined by a combination of two or more of the above decisions.

[0143] The actions in the proposal and others may be combined. Also, instead of two types of priorities (HP and LP), three or more types of priorities may be applied in the present disclosure.

[0144] <Terminal Capabilities> The UE capability indicating the capabilities of the terminal may include the following information indicating the capabilities of the terminal: Note that the information indicating the capabilities of the terminal may correspond to information defining the capabilities of the terminal. Information defining whether the terminal supports collision handling between HP CG PUSCH and LP DG PUSCH Information defining whether the terminal supports collision handling between HP CG PUSCH and LP DG PUSCH in repetition Information defining whether the terminal supports collision handling between LP CG PUSCH and HP DG PUSCH Information defining whether the terminal supports collision handling between LP CG PUSCH and HP DG PUSCH in repetition

[0145] <Wireless system configuration> 15 is a diagram illustrating an example of a wireless communication system 10 according to an embodiment. The wireless communication system 10 is a wireless communication system conforming to 5G New Radio (NR), and includes a Next Generation-Radio Access Network 20 (hereinafter, NG-RAN 20) and a terminal 200 (hereinafter, UE 200).

[0146] The wireless communication system 10 may be a wireless communication system conforming to a system called Beyond 5G, 5G Evolution, or 6G.

[0147] The NG-RAN 20 includes a base station 100A (hereinafter, gNB100A) and a base station 100B (hereinafter, gNB100B). When there is no need to distinguish between the gNB100A, gNB100B, etc., they are collectively referred to as gNB100. Furthermore, the number of gNBs and UEs is not limited to the example shown in FIG. 15.

[0148] The NG-RAN 20 actually includes a plurality of NG-RAN nodes, specifically, gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). The NG-RAN 20 and the 5GC may be simply referred to as a "network."

[0149] The gNB100A and the gNB100B are base stations conforming to 5G and perform 5G wireless communication with the UE200. The gNB100A, the gNB100B, and the UE200 may support Massive Multiple-Input Multiple-Output (MIMO), which generates a more directional beam (BM) by controlling radio signals transmitted from multiple antenna elements, Carrier Aggregation (CA), which aggregates and uses multiple component carriers (CCs), and Dual Connectivity (DC), which performs communication between the UE and each of two NG-RAN nodes. DC may include Multi-RAT Dual Connectivity (MR-DC) using a Master Cell Group (MCG) and a Secondary Cell Group (SCG). Examples of MR-DC include E-UTRA-NR Dual Connectivity (EN-DC), NR-EUTRA Dual Connectivity (NE-DC), and NR-NR Dual Connectivity (NR-DC). Here, CCs (cells) used in CA may be considered to constitute the same cell group. The MCG and SCG may be considered to constitute the same cell group.

[0150] Furthermore, the wireless communication system 10 supports a plurality of frequency ranges (FR).

[0151] Fig. 16 is a diagram showing an example of frequency ranges used in the wireless communication system 10. As shown in Fig. 16, the wireless communication system 10 corresponds to FR1 and FR2. The frequency bands of each FR are, for example, as follows: FR1: 410 MHz to 7.125 GHz FR2: 24.25 GHz~52.6 GHz

[0152] FR1 may use a Sub-Carrier Spacing (SCS) of 15 kHz, 30 kHz, or 60 kHz, and may use a bandwidth (BW) of 5 to 100 MHz. FR2 is a higher frequency than FR1, and may use an SCS of 60 kHz or 120 kHz (240 kHz may be included), and may use a bandwidth (BW) of 50 to 400 MHz.

[0153] The SCS may be interpreted as a numerology, which is defined in 3GPP TS38.300 and corresponds to one subcarrier spacing in the frequency domain.

[0154] Furthermore, the wireless communication system 10 may support a frequency band higher than the FR2 frequency band. Specifically, the wireless communication system 10 may support a frequency band exceeding 52.6 GHz up to 114.25 GHz. For convenience, such a high frequency band may be referred to as "FR2x." When using a frequency band exceeding 52.6 GHz, Cyclic Prefix-Orthogonal Frequency Division Multiplexing (CP-OFDM) / Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) with a larger SCS may be applied.

[0155] Fig. 17 is a diagram showing an example of the configuration of a radio frame, subframe, and slot used in the radio communication system 10. As shown in Fig. 17, one slot is made up of 14 symbols, and the larger (wider) the SCS is, the shorter the symbol period (and slot period) becomes. The SCS is not limited to the interval (frequency) shown in Fig. 17. For example, 480 kHz, 960 kHz, etc. may be used as the SCS.

[0156] Also, the number of symbols constituting one slot does not necessarily have to be 14 (for example, 28 or 56 symbols). Furthermore, the number of slots per subframe may differ depending on the SCS.

[0157] The time direction (t) shown in Fig. 17 may be called a time domain, a symbol period, a symbol time, etc. The frequency direction may be called a frequency domain, a resource block, a subcarrier, a bandwidth part (BWP), etc.

[0158] <Base station configuration> 18 is a block diagram showing an example of the configuration of base station 100 according to the embodiment. Base station 100 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. Base station 100 communicates with terminal 200 (see FIG. 19) wirelessly.

[0159] The transmitter 101 transmits a downlink (DL) signal to the terminal 200. For example, the transmitter 101 transmits the DL signal under the control of the controller 103.

[0160] The DL signal may include, for example, a downlink data signal and control information (e.g., Downlink Control Information (DCI)). The DL signal may also include information indicating scheduling related to signal transmission of terminal 200 (e.g., an UL grant). The DL signal may also include control information of higher layers (e.g., control information of Radio Resource Control (RRC)). The DL signal may also include a reference signal.

[0161] Channels used for transmitting DL signals include, for example, data channels and control channels. For example, the data channels may include a PDSCH (Physical Downlink Shared Channel), and the control channels may include a PDCCH (Physical Downlink Control Channel). For example, base station 100 transmits control information to terminal 200 using the PDCCH and transmits downlink data signals using the PDSCH.

[0162] The reference signal included in the DL signal may include at least one of a demodulation reference signal (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 position information. For example, reference signals such as DMRS and PTRS are used for demodulating downlink data signals and are transmitted using the PDSCH.

[0163] The receiving unit 102 receives an uplink (UL) signal transmitted from the terminal 200. For example, the receiving unit 102 receives the UL signal under the control of the control unit 103.

[0164] The control unit 103 controls the communication operations of the base station 100, including the transmission processing of the transmission unit 101 and the reception processing of the reception unit .

[0165] For example, the control unit 103 acquires information such as data and control information from the upper layer and outputs it to the transmitting unit 101. The control unit 103 also outputs the data, control information, etc. received from the receiving unit 102 to the upper layer.

[0166] For example, control unit 103 allocates resources (or channels) used for transmitting and receiving DL signals and / or resources used for transmitting and receiving UL signals based on signals (e.g., data and control information, etc.) received from terminal 200 and / or data and control information, etc. acquired from a higher layer. Information related to the allocated resources may be included in control information transmitted to terminal 200.

[0167] Control section 103 configures PUCCH resources as an example of allocation of resources used for transmitting and receiving UL signals. Information relating to PUCCH configuration such as a PUCCH cell timing pattern (PUCCH configuration information) may be reported to terminal 200 by RRC.

[0168] <Device configuration> 19 is a block diagram showing an example of the configuration of terminal 200 according to the embodiment. Terminal 200 includes, for example, receiving section 201, transmitting section 202, and control section 203. Terminal 200 communicates with base station 100, for example, wirelessly.

[0169] The receiving unit 201 receives a DL signal transmitted from the base station 100. For example, the receiving unit 201 receives the DL signal under the control of the control unit 203.

[0170] The transmitter 202 transmits the UL signal to the base station 100. For example, the transmitter 202 transmits the UL signal under the control of the controller 203.

[0171] The UL signal may include, for example, an uplink data signal and control information (e.g., UCI). For example, information related to the processing capability of terminal 200 (e.g., UE capability) may be included. The UL signal may also include a reference signal.

[0172] Channels used for transmitting UL signals include, for example, data channels and control channels. For example, the data channels include a PUSCH (Physical Uplink Shared Channel), and the control channels include a PUCCH (Physical Uplink Control Channel). For example, terminal 200 receives control information from base station 100 using the PUCCH and transmits uplink data signals using the PUSCH.

[0173] The reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, the reference signals such as DMRS and PTRS are used for demodulating the uplink data signal and are transmitted using an uplink channel (for example, PUSCH).

[0174] The control unit 203 controls the communication operations of the terminal 200 , including the reception processing in the reception unit 201 and the transmission processing in the transmission unit 202 .

[0175] For example, the control unit 203 acquires information such as data and control information from a higher layer and outputs it to the transmitting unit 202. Also, the control unit 203 outputs, for example, the data and control information received from the receiving unit 201 to the higher layer.

[0176] For example, the control unit 203 controls transmission of information to be fed back to the base station 100. The information to be fed back to the base station 100 may include, for example, HARQ-ACK, Channel State Information (CSI), or a Scheduling Request (SR). The information to be fed back to the base station 100 may be included in UCI. The UCI is transmitted in the resources of the PUCCH.

[0177] Control unit 203 configures PUCCH resources based on configuration information (for example, configuration information such as a PUCCH cell timing pattern and / or DCI notified by RRC) received from base station 100. Control unit 203 determines PUCCH resources to be used for transmitting information to be fed back to base station 100. Under the control of control unit 203, transmission unit 202 transmits the information to be fed back to base station 100 in the PUCCH resources determined by control unit 203.

[0178] Note that the channel used for transmitting the DL signal and the channel used for transmitting the UL signal are not limited to the above-mentioned examples. For example, the channel used for transmitting the DL signal and the channel used for transmitting the UL signal may include a Random Access Channel (RACH) and a Physical Broadcast Channel (PBCH). The RACH may be used to transmit Downlink Control Information (DCI) including a Random Access Radio Network Temporary Identifier (RA-RNTI), for example.

[0179] Here, the transmitter 202 may transmit, by repetition, one or both of a first uplink signal having a first priority and for which uplink transmission is set and permitted, and a second uplink signal having a second priority lower than the first priority and for which uplink transmission is dynamically permitted. The first uplink signal may correspond to an HP CG PUSCH, and the second uplink signal may correspond to an LP DG PUSCH.

[0180] The control unit 203 may determine to drop the second uplink signal whose transmission timing overlaps (overlaps in time) with the first uplink signal.

[0181] With the above configuration, when a terminal transmits one or both of a first uplink signal and a second uplink signal in a repetitive manner and the first uplink signal and the second uplink signal overlap, the terminal can appropriately transmit the first uplink signal having a higher priority.

[0182] Furthermore, the control unit 203 may determine to transmit a second uplink signal whose transmission timing does not overlap with that of the first uplink signal.

[0183] With the above configuration, the terminal can properly transmit the second uplink signal whose transmission timing does not overlap with that of the first uplink signal.

[0184] Furthermore, the control unit 203 may determine to transmit some of the second uplink signals whose transmission timings do not overlap with those of the first uplink signals.

[0185] With the above configuration, the terminal can appropriately transmit a portion of the second uplink signal whose transmission timing does not overlap with that of the first uplink signal. Also, by transmitting a portion of the second uplink signal whose transmission timing does not overlap with that of the first uplink signal, the terminal can reduce power consumption.

[0186] Furthermore, the control unit 203 may decide to drop all second uplink signals whose transmission timing does not overlap with that of the first uplink signal.

[0187] With the above configuration, the terminal can reduce power consumption.

[0188] Here, the transmitter 202 may repeatedly transmit one or both of a first uplink signal having a first priority and for which uplink transmission is set and permitted, and a second uplink signal having a second priority higher than the first priority and for which uplink transmission is dynamically permitted. The first uplink signal may correspond to a low-pass count (LP) CG PUSCH, and the second uplink signal may correspond to a high-pass count (HP) DG PUSCH.

[0189] The control unit 203 may determine to drop the second uplink signal whose transmission timing overlaps with that of the first uplink signal.

[0190] With the above configuration, when the terminal transmits one or both of the first uplink signal and the second uplink signal in a repetitive manner and the first uplink signal and the second uplink signal overlap, the terminal can appropriately transmit the second uplink signal, which has a higher priority.

[0191] The control unit 203 may determine to transmit the first uplink signal whose transmission timing does not overlap with that of the second uplink signal.

[0192] With the above configuration, the terminal can properly transmit the first uplink signal whose transmission timing does not overlap with that of the first uplink signal.

[0193] Furthermore, the control unit 203 may determine to transmit some of the first uplink signals whose transmission timings do not overlap with those of the second uplink signals.

[0194] With the above configuration, the terminal can appropriately transmit a portion of the first uplink signal whose transmission timing does not overlap with that of the second uplink signal. Also, by transmitting a portion of the first uplink signal whose transmission timing does not overlap with that of the second uplink signal, the terminal can reduce power consumption.

[0195] Furthermore, the control unit 203 may decide to drop all of the first uplink signals whose transmission timing does not overlap with that of the second uplink signal.

[0196] With the above configuration, the terminal can reduce power consumption.

Furthermore, "judgment" and "decision" can include regarding resolving, selecting, choosing, establishing, comparing, etc. as having been "judged" or "decided." In other words, "judgment" and "decision" can include regarding some action as having been "judged" or "decided." Furthermore, "judgment (decision)" can be interpreted as "assuming," "expecting," "considering," etc.

[0246] The terms "connected," "coupled," or any variation thereof, refer to 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" to each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, "connected" may be read as "access." As used in this disclosure, two elements may be considered to be "connected" or "coupled" to each other using one or more wires, cables, and / or printed electrical connections, as well as electromagnetic energy having wavelengths in the radio frequency range, microwave range, and optical (both visible and invisible) range, as some non-limiting and non-exhaustive examples.

[0247] <Reference signal> The reference signal may be abbreviated as RS (Reference Signal) or may be called a pilot depending on the applicable standard.

[0248] <The meaning of "based on"> As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

[0249] <"First", "Second"> As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0250] <Means> In the configurations of each of the above devices, the "means" may be replaced with a "section", "circuit", "device", etc.

[0251] <Open format> In the present disclosure, when the terms "include", "including" and their variants are used, these terms are intended to be inclusive, similar to the term "comprising". Further, the term "or" used in the present disclosure is not intended to be an exclusive disjunction.

[0252] <Time units such as TTI, frequency units such as RB, radio frame configuration> A radio frame may be composed of one or more frames in the time domain. Each of the one or more frames in the time domain may be referred to as a sub-frame. A sub-frame may further be composed of one or more slots in the time domain. The sub-frame may have a fixed time length (e.g., 1 ms) that does not depend on numerology.

[0253] Numerology may be a communication parameter applied to at least one of the transmission and reception of a certain signal or channel. Numerology may indicate, for example, at least one of sub-carrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, specific filtering processing performed by a transceiver in the frequency domain, specific windowing processing performed by a transceiver in the time domain, etc.

[0254] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may be a time unit based on numerology.

[0255] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot 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.

[0256] The radio frame, subframe, slot, minislot, and symbol all represent time units for transmitting signals, and may be referred to by other names corresponding to the radio frame, subframe, slot, minislot, and symbol.

[0257] 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 minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0258] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. However, the definition of TTI is not limited to this.

[0259] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0260] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0261] A TTI having a time length of 1 ms may be called a regular TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0262] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and equal to or greater than 1 ms.

[0263] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may also be determined based on numerology.

[0264] The time domain of an RB may include one or more symbols and may have a length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

[0265] Note that one or more RBs may also be called a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, or the like.

[0266] 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.

[0267] A Bandwidth Part (BWP) (which may also be referred to as a fractional bandwidth) may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a common reference point of the carrier. PRBs may be defined in a given BWP and numbered within that BWP.

[0268] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0269] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0270] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio 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, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0271] <Maximum transmission power> The "maximum transmit power" in this disclosure may mean the maximum value of transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0272] <Article> In this disclosure, where articles are added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.

[0273] <"Different"> In the present 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 "coupled" may also be interpreted in the same way as "different." [Industrial Applicability]

[0274] One aspect of the present disclosure is useful in wireless communication systems. [Explanation of symbols]
