[0035] (Resource Sharing)

[0036] In future wireless communication systems (for example, Rel. 18 and later), resource sharing is being studied for the purpose of improving the efficiency of use of frequency bands (existing frequency bands and new high frequency bands).

[0037] In resource sharing, a Radio Access Network (RAN) is shared by multiple operators (operators, MNOs), and network (NW, for example, base stations) investment costs are divided for each operator, so that multiple base stations can be installed.

[0038] For example, by having multiple operators share antennas / sites (land / towers, etc.), the multiple operators can share station installation costs.

[0039] In addition, by sharing (eg, sharing hardware infrastructure) a distributed node (eg, a distributed unit (DU)) / aggregation node (eg, a central unit (CU))) by multiple operators, the multiple operators can share the equipment costs.

[0040] Furthermore, by sharing frequency / antenna units (eg, radio units (RU)) among multiple operators, resource utilization efficiency can be improved, for example, other operators can use resources not used by a certain operator.

[0041] Figure 1A-Figure 1D This is a diagram showing an example of network sharing.

[0042] Figure 1A An example of site sharing is shown in FIG. Figure 1A As shown, in site sharing, multiple operators share antennas / sites. On the other hand, for service platforms, HSS (Home Subscriber Server) / HLR (Home Location Register), Core Network (CN) Packet Switching (PS), base stations, and cells / frequencies, each of the multiple operators is independent.

[0043] Figure 1B An example of MORAN (Multi Operator RAN) is shown. Figure 1BAs shown, in MORAN, in addition to antennas / sites, multiple operators also share a part of the base station (e.g., the hardware of the base station). On the other hand, for the service platform, HSS / HLR, CN PS, other parts of the base station (e.g., the software of the base station) and cells / frequencies, each of the multiple operators is independent.

[0044] Figure 1C An example of MOCN (Multi Operator Core Network) is shown. Figure 1C As shown, in MOCN, base stations and cells / frequencies are shared by multiple operators. On the other hand, for service platforms, HSS / HLR and CN PS, each of the multiple operators is independent.

[0045] Figure 1D An example of GWCN (Gateway Core Network) is shown. Figure 1D As shown, in GWCN, multiple operators share CN PS, base stations, and cells / frequencies. On the other hand, each of the multiple operators is independent in terms of service platform and HSS / HLR.

[0046] In MOCN / GWCN, since cells are shared by multiple operators, it is desirable to be able to change settings for each operator (mobile network operator (MNO)) (for example, for each ID (PLMN ID) related to the Public Land Mobile Network (PLMN)).

[0047] For example, in existing specifications, whether to allow initial access to a cell, a tracking area code, a unique cell ID within a PLMN, etc. can be set for each PLMN ID (for each MNO).

[0048] On the other hand, for a terminal in the RRC connected state (user terminal, User Equipment (UE)), the operator's individual settings can be set as RRC settings (configuration) according to the PLMN ID of the terminal. Specifically, in resource sharing, when it is desired that only terminals of a specific operator can use a portion of the time resources of a shared cell, it is also conceivable to set it so that the time resources are not used in terminals of other operators.

[0049] (MNO Priority Resources)

[0050] Figure 2 FIG. 1 is a diagram showing an example of setting time / frequency resources when resource sharing is applied. Figure 2 In the present invention, the time resource setting (TDD setting #1 and TDD setting #2) corresponding to the first MNO (MNO#1), the frequency resource setting (BWP setting #1 and BWP setting #3) corresponding to the first MNO, the time resource setting (TDD setting #1) corresponding to the second MNO (MNO#2), and the frequency resource setting (BWP setting #2) corresponding to the second MNO are set for the UE as common wireless resource settings for the cell.

[0051] exist Figure 2 In the example shown, "D" represents a DL symbol, "U" represents a UL symbol, and "F" represents a flexible symbol. A flexible symbol can be a symbol whose transmission direction can be changed, or it can be an MNO corresponding to a resource containing a flexible symbol (in Figure 2 MNO#1 in the Figure 2 The code elements in the figure are those that can be used by the UE corresponding to MNO#2).

[0052] Some DL / UL settings (time resources) / BWP (frequency resources) are associated with information for identifying the MNO, and the UE of each MNO can also use this time / frequency resource to send and receive DL / UL signals. Figure 2 In the example shown, the UE may determine available time / frequency resources based on information identifying its own MNO and according to the common radio resource settings of the set cell.

[0053] exist Figure 2 In the example shown, the UE corresponding to MNO#1 cannot use the time / frequency resources corresponding to MNO#2 (for example, the frequency resources configured by TDD configuration #1 / BWP configuration #2).

[0054] In addition, Figure 2 In the example shown, the UE corresponding to MNO#2 cannot utilize the DL symbols / UL symbols in the time / frequency resources corresponding to MNO#1 (for example, the time / frequency resources set by TDD setting # / BWP#1, TDD setting #2 / BWP setting #3).

[0055] On the other hand, the UE corresponding to MNO#2 can also use the flexible codewords in the time / frequency resources corresponding to MNO#1 if certain conditions are met. The resources for which flexible codewords are set and included in the resources used by a certain MNO can also be called MNO priority resources (in Figure 2In addition, in the present disclosure, priority resources are not limited to resources that are set flexibly. Priority resources may also be set / indicated from the base station to the UE (for example, through a higher layer parameter / MAC CE / DCI).

[0056] The specific condition (for example, the condition that the priority resources of a certain MNO can be utilized by other MNOs) may also be at least one of: the DL / UL scheduling for the priority resources is indicated to the UEs of other MNOs, the DL / UL settings for the priority resources (for example, DCI format 2_0) are notified to the UEs of other MNOs, and the UEs of other MNOs do not detect the DL / UL signals of other UEs (for example, UEs corresponding to the MNO of the priority resources) (for example, the received power becomes below a threshold).

[0057] <Traffic type>

[0058] In future wireless communication systems (e.g., NR), it is envisioned that mobile broadband will be further advanced (e.g., enhanced Mobile Broadband (eMBB)), machine-type communications that enable multiple simultaneous connections (e.g., massive Machine Type Communications (mMTC) and Internet of Things (IoT)), and high-reliability and low-latency communications (e.g., Ultra-Reliable and Low-Latency Communications (URLLC)) will be business types (also referred to as services, service types, communication types, use cases, etc.). For example, in URLLC, smaller latency and higher reliability are required than in eMBB.

[0059] In the physical layer, the service type may also be identified based on at least one of the following.

[0060] Logical channels with different priorities

[0061] Modulation and Coding Scheme (MCS) table (MCS index table)

[0062] Channel Quality Indication (CQI) table

[0063] DCI format

[0064] The scrambled (masked) (Radio Network Temporary Identifier (RNTI: System Information - Radio Network Temporary Identifier)) of the (additional) cyclic redundancy check (CRC) bits contained in the DCI (DCI format)

[0065] RRC (Radio Resource Control) parameters

[0066] Specific RNTI (e.g., RNTI for URLLC, MCS-C-RNTI, etc.)

[0067] Search space

[0068] Specific fields within DCI (e.g., newly added fields or reuse of existing fields)

[0069] Specifically, the service type of HARQ-ACK for PDSCH may also be determined based on at least one of the following.

[0070] An MCS index table for determining at least one of the modulation order, target code rate, and transport block size (TBS) of the PDSCH (e.g., whether to use MCS index table 3)

[0071] RNTI used in CRC scrambling of the DCI used for scheduling the PDSCH (e.g., which one of the C-RNTI and the MCS-C-RNTI is used for CRC scrambling)

[0072] In addition, the service type of the SR may also be determined based on a higher-layer parameter used as an identifier (SR-ID) of the SR. The higher-layer parameter may also indicate whether the service type of the SR is eMBB or URLLC.

[0073] In addition, the service type of CSI may also be determined based on the configuration information (CSIreportSetting) related to the CSI report, the DCI type or DCI transmission parameter used in the trigger, etc. The configuration information, DCI type, etc. may also indicate whether the service type of the CSI is eMBB or URLLC. In addition, the configuration information may also be a high-level parameter.

[0074] In addition, the service type of PUSCH may also be determined based on at least one of the following.

[0075] An MCS index table for determining at least one of the modulation order, target coding rate, and TBS of the PUSCH (e.g., whether to use MCS index table 3)

[0076] RNTI used in CRC scrambling of the DCI used for scheduling the PUSCH (e.g., which of the C-RNTI and the MCS-C-RNTI is used for CRC scrambling)

[0077] The service type may be associated with communication requirements (such as delay and error rate, and request conditions), data type (such as voice and data), and the like.

[0078] The difference between the requirements of URLLC and the requirements of eMBB may be that the latency of URLLC is smaller than the latency of eMBB, or that the requirements of URLLC include reliability requirements.

[0079] For example, the requirements for the user (U) plane delay of eMBB may also include a U-plane delay of 4 ms for the downlink and a U-plane delay of 4 ms for the uplink. On the other hand, the requirements for the U-plane delay of URLLC may also include a U-plane delay of 0.5 ms for the downlink and a U-plane delay of 0.5 ms for the uplink. In addition, the requirements for the reliability of URLLC may also include a U-plane delay of 1 ms and an error rate of 10 for 32 bytes. -5 .

[0080] In addition, as enhanced Ultra Reliable and Low Latency Communications (eURLLC), research is being conducted mainly on improving the reliability of services for unicast data. In the following, when no distinction is made between URLLC and eURLLC, URLLC is referred to as URLLC.

[0081] <Priority setting>

[0082] In NR after Rel.16, a study is underway to set multiple levels (e.g., 2 levels) of priority for a specific signal or channel. The priority may also be the priority of UL transmission within the UE (e.g., Intra-UE UL prioritization).

[0083] For example, it is assumed that different priorities are set for each signal or channel corresponding to different business types (also referred to as services, service types, communication types, use cases, etc.) to control communication (e.g., transmission control in case of conflict, etc.). Thus, different priorities can be set for the same signal or channel according to the service type, etc. to control communication.

[0084] The priority may be set for at least one of a signal (e.g., UCI such as HARQ-ACK, reference signal, etc.), a channel (PDSCH, PUSCH, PUCCH, etc.), a reference signal (e.g., channel state information (CSI), sounding reference signal (SRS), etc.), a scheduling request (SR), and a HARQ-ACK codebook. In addition, priorities may be set for the PUCCH used for sending SR, the PUCCH used for sending HARQ-ACK, and the PUCCH used for sending CSI.

[0085] The priority may also be defined by a first priority (e.g., high) and a second priority (e.g., low) lower than the first priority. Hereinafter, the first priority is also denoted as HP and the second priority is denoted as LP. Alternatively, three or more priorities may be set.

[0086] The UE may also determine the priority of each UL transmission based on a specific field of the DCI (e.g., a priority indicator field (PriorityIndicatorfield)) and at least one of the higher-level parameters related to the priority. Any of the following may also be applied as an indication of the priority of each UL transmission (e.g., each channel / signal).

[0087] 《SR》

[0088] For the SR sent in the PUCCH, the priority may also be set through a higher layer parameter (eg, schedulingRequestPriority).

[0089] HARQ-ACK

[0090] For HARQ-ACK sent in PUCCH, the priority can also be set by DCI / high-level parameters. For example, for HARQ-ACK corresponding to a dynamic PDSCH (e.g., a PDSCH dynamically scheduled by DCI), the priority can also be indicated by a specific field of DCI (e.g., a priority indicator). For HARQ-ACK corresponding to a semi-persistent PDSCH (SPS PDSCH), the priority can also be set by high-level parameters (e.g., HARQ-ACK-Codebook-indicator-forSPS).

[0091] CSI

[0092] For periodic / semi-persistent CSI (P / SP-CSI) sent in PUCCH, the priority can also be fixedly set / defined (e.g., low). For aperiodic / semi-persistent CSI (A / SP-CSI) sent via PUSCH, the priority can also be indicated by a specific field of DCI (e.g., Priority Indicator).

[0093] PUSCH

[0094] For PUSCH, the priority can also be set by DCI / high-layer parameters. For example, for a dynamically permitted PUSCH (e.g., a PUSCH scheduled by DCI), the priority can also be indicated by a specific field of DCI (e.g., a priority indicator). For a set permitted PUSCH (e.g., a PUSCH set by RRC), the priority can also be set by a high-layer parameter (e.g., priority).

[0095] SRS

[0096] For aperiodic SRS (A-SRS) triggered by periodic / semi-persistent SRS (P / SP-SRS) and DCI format 2_3, the priority may also be fixedly set / defined (eg, low).

[0097] (Conflict handling of UL transmission)

[0098] In the case where multiple UL signals / UL channels (eg, scheduled / triggered UL signals / UL channels) overlap, the UE may also control UL transmission based on priority. Overlap may also be rewritten as duplication or conflict.

[0099] The so-called overlapping of multiple UL signals / UL channels may also refer to the situation where the time resources (or time resources and frequency resources) of multiple UL signals / UL channels overlap or the situation where the transmission timing of multiple UL signals / UL channels overlap. The time resource may also be rewritten as a time domain or a time domain. The time resource may also be a symbol, a time slot, a sub-time slot or a sub-frame unit.

[0100] The overlapping of multiple UL signals / UL channels in the same UE (e.g., intra-UE) may also mean that multiple UL signals / UL channels overlap at least in the same time resource (e.g., symbol). In addition, the collision of UL signals / UL channels in different UEs (e.g., inter-UE) may also mean that multiple UL signals / UL channels overlap in the same time resource (e.g., symbol) and frequency resource (e.g., RB).

[0101] For example, when a plurality of UL signals / UL channels with the same priority overlap, the UE controls so that the plurality of UL signals / UL channels are multiplexed / mapped to one UL channel and transmitted (see Figure 3A ).

[0102] exist Figure 3A , a case where a HARQ-ACK (or a PUCCH for sending HARQ-ACK) with a first priority (HP) set overlaps with UL data / UL-SCH (or a PUSCH for sending UL data / UL-SCH) with a first priority (HP) set is shown. In this case, the UE multiplexes (or maps) the HARQ-ACK to the PUSCH and sends both the UL data and the HARQ-ACK.

[0103] In the case where multiple UL signals / UL channels with different priorities overlap, the UE may also perform control so that a high-priority UL transmission is performed (for example, a high-priority UL transmission is given priority) and a low-priority UL transmission is not performed (for example, a discard is made) (see Figure 3B ).

[0104] exist Figure 3B, a situation where UL data / HARQ-ACK (or, UL channel for sending UL data / HARQ-ACK) set to a first priority (HP) and UL data / HARQ-ACK (or, UL channel for sending UL data / HARQ-ACK) set to a second priority (LP) overlap is shown. In this case, the UE controls so that the UL data / HARQ-ACK with a low priority is discarded and the UL data / HARQ-ACK with a high priority is prioritized and sent. In addition, the UE can also change (for example, postpone or shift) the transmission timing of the UL transmission with a low priority.

[0105] In the case where more than two (or more than three) UL signals / UL channels overlap in the time domain, the transmission can be controlled in a maximum of four steps (see Figure 4 ).

[0106] In step 1, one UL channel is selected for multiplexing UL signals transmitted in UL transmissions with low priority (resolution of conflicts between UL transmissions with low priority). Figure 4 In the present invention, HARQ-ACK (or, PUCCH for HARQ-ACK transmission) and data (or, PUSCH for data / UL-SCH transmission) with the second priority (LP) can also be multiplexed into a specific UL channel (here is PUSCH).

[0107] In step 2, control can also be performed so that among UL transmissions with different priorities, the UL transmission with a higher priority is given priority and the UL transmission with a lower priority is discarded (resolution of conflicts between UL transmissions with different priorities). Figure 4 In the process, the PUCCH for SR transmission and the PUCCH for HARQ-ACK transmission with the first priority (HP) may be prioritized, and the PUSCH for HARQ-ACK and data transmission with the second priority (LP) may be discarded.

[0108] In step 3, one UL channel is selected for multiplexing UL signals transmitted in the high-priority UL transmissions (resolution of conflicts between high-priority UL transmissions). Figure 4 In the UL, SR (or, PUCCH for SR transmission) and HARQ-ACK (or, PUCCH for HARQ-ACK transmission) with the first priority (HP) can also be multiplexed to a specific UL channel (here is PUCCH for HARQ-ACK transmission).

[0109] After performing step 3, in the event of a conflict between UL transmissions of different priorities (if this situation still remains), as step 4, control is performed so that among the UL transmissions of different priorities, the UL transmission with a higher priority is given priority and the UL transmission with a lower priority is discarded.

[0110] Like this, the UE resolves the conflict between multiple UL transmissions with low priority through step 1, resolves the conflict between multiple UL transmissions with different priorities (if any) through step 2, resolves the conflict between multiple UL transmissions with high priority through step 3, and resolves the conflict between multiple UL transmissions with different priorities (if any) through step 4.

[0111] In addition, Figure 4 In step 3, multiplexing is performed between high-priority UL transmissions, but the present invention is not limited thereto. For example, in step 1, multiplexing between low-priority UL transmissions and high-priority UL transmissions in the overlapped multiple UL transmissions may be performed separately.

[0112] (Considering the conflict handling of UL transmission of MNO priority resources)

[0113] In future wireless communication systems, such as Figure 2 As shown, it is also assumed that the setting of resources corresponding to a certain MNO (e.g., MNO priority resources) is supported. In this case, the priority resources of a certain MNO (e.g., Figure 2 In the case where the resources used in the UL transmission of another MNO (e.g., MNO#1) overlap, the resources used in the UL transmission of another MNO (e.g., MNO#2) overlap. Furthermore, the case where multiple resources used in the UL transmission of another MNO overlap is also considered (refer to Figure 5 ).

[0114] Figure 5 The case where the resources used by MNO#1 (MNO#1 priority resources) and a part of UL transmission #1 (e.g., PUCCH resources) of MNO#2 overlap, and the UL transmission #1 of MNO#2 and other UL transmission #2 of MNO#2 (e.g., PUSCH resources) overlap. In addition, in the present disclosure, UL transmission can also be rewritten as resources used in UL transmission.

[0115] In the case where UL transmission of other MNOs is carried out within the priority resources of a certain MNO (for example, in the case where the priority resources of a certain MNO conflict with the UL transmission resources of other MNOs), the transmission of the MNO corresponding to the priority resources can be given priority, and the transmission of other MNOs can be discarded / cancelled (conflict handling based on priorities between MNOs).

[0116] In such a case, how to control the conflict handling process of UL transmission in the UE becomes a problem. For example, how to control UL transmission (for example, the order of processing such as multiplexing / discarding) based on MNO priority resources (or, inter-MNO priority processing) / UL transmission resource priority (or, inter-UL transmission priority processing) becomes a problem.

[0117] Therefore, when introducing / supporting resource sharing (or, MNO priority resources), the inventors of the present invention focused on the situation where other MNO priority resources overlap with more than one UL transmissions, studied the UL transmission control (for example, conflict handling) in such situations, and came up with a method of the present embodiment.

[0118] (UL transmission priority between UEs)

[0119] In Rel.15 / 16, a group-common DCI (eg, DCI format 2_4) indicating cancellation of scheduled UL transmission is supported.

[0120] DCI format 2_4 is used to notify the cancellation of the corresponding UL transmitted PRB and codeword. For example, the UE may also determine the cancellation of the UL transmitted PRB and codeword based on the information (eg, cancellation indication) included in the DCI format 2_4.

[0121] Indications based on DCI format 2_4 can also be applied to PUSCH transmission / SRS transmission. In the case where PUSCH transmission / SRS transmission is scheduled by DCI format, instructions based on DCI format 2_4 are applied to PUSCH transmission or SRS transmission only when the last codeword received by the PDCCH corresponding to the DCI format is earlier than the first codeword received by the PDCCH corresponding to DCI format 2_4.

[0122] In addition, the UE can also apply / interpret the information notified by DCI format 2_4 based on the last timing of PDCCH reception of DCI format 2_4 / the last codeword of the control resource set of DCI format 2_4, thereby controlling PUSCH transmission / SRS transmission.

[0123] In addition, the UE does not expect to cancel PUSCH transmission or SRS transmission before a specific symbol after detecting the last symbol of the control resource set of DCI format 2_4.

[0124] When receiving a DCI (e.g., DCI format 2_4) indicating cancellation of UL transmission, the UE may also decide whether to cancel the UL transmission based on the priority of the UL transmission. For example, when the priority of the UL transmission scheduled in the resource indicated by the DCI (e.g., UL CI) is low, the UE cancels the UL transmission. On the other hand, for example, when the priority of the UL transmission scheduled in the resource indicated by the DCI is high, the UE performs the UL transmission.

[0125] Assume that in the resource for which cancellation of UL transmission is indicated, a UL transmission #1 with a low priority (e.g., eMBB) and a UL transmission #2 with a high priority (e.g., URLLC) overlap (see Figure 6 ).

[0126] exist Figure 6 In the example, UE#1 is scheduled to send UL #1 (low priority) through the first DCI, UE#2 is scheduled to send UL #2 (high priority) through another second DCI, and the scheduling of UL #1 and UL #2 overlap. The base station sends a third DCI (for example, DCI format 2_4) indicating the cancellation of UL transmission. Here, it is shown that after the third DCI is sent, the second DCI is sent (or the scheduling of UL transmission #2 is indicated).

[0127] In this case, UE#1 cancels UL transmission #1 (low) overlapping with the resource indicated for cancellation. On the other hand, UE#2 transmits without canceling UL transmission #2 (high) overlapping with the resource indicated for cancellation. Thus, even when UL transmissions between different UEs overlap and are scheduled, by indicating cancellation by DCI, UL transmissions with low priority can be selectively canceled. In other words, by utilizing the cancellation indication, UL transmissions overlapping between UEs can be scheduled.

[0128] As described above, in future wireless communication systems, resource sharing among multiple MNOs is being studied. In existing systems (e.g., before Rel. 17), specific UL transmissions (e.g., low priority PUSCH / SRS) are canceled using a cancellation-indicated DCI (e.g., UL CI) without distinguishing between MNOs.

[0129] When resources are shared among multiple MNOs, it is also assumed that a cancellation indication of UL transmission using DCI or the like can be supported (see Figure 7 ). In such a case, how to control the cancellation instruction becomes a problem.

[0130] exist Figure 7In the example, a case where a cancellation indication of UL transmission is supported when resources are shared among multiple MNOs is shown. Here, a case is shown where at least one of UL transmission #1 corresponding to MNO #1 and UL transmission #2 corresponding to MNO #2 is scheduled, and the cancellation of UL transmission is indicated for resources overlapping with UL transmission #1 / UL transmission #2 (UL transmission #1 / UL transmission #2 is the object of cancellation). In this case, how to control the cancellation of UL transmission has not been fully studied. For example, how to control the cancellation by considering the priority between MNOs and the priority of UL transmission of each MNO has become a problem.

[0131] Therefore, the inventors of the present invention have studied on the cancellation control of UL transmission when introducing / supporting resource sharing (or MNO priority resources), and have conceived another aspect of the present embodiment.

[0144] (Wireless Communication Method)

[0145] The UE may determine at least one setting information (setting / notification parameter) of resources related to DL / UL signals based on the information identifying the MNO.

[0146] In the present disclosure, the information for identifying the MNO may be information related to the PLMN (for example, PLMN ID) or an ID (sub-ID) for indicating / specifying an arbitrary group (specific group).

[0147] In the present disclosure, the information for identifying the MNO may also be UE-specific information. More than one piece of information for identifying the MNO may also be specified for the UE. The information for identifying the MNO may be fixed information for the UE or information that is changed / selected during communication.

[0148] In addition, for example, the configuration information (configuration / notification parameter) of resources related to the DL / UL signal may be configuration information (configuration / notification parameter) related to the DL / UL bandwidth part (BWP).

[0149] The DL / UL BWP used (available) by the UE may also be determined based on the information for identifying the MNO. For example, the start / end frequency resource (e.g., PRB) of the DL / UL BWP used (available) by the UE may also be represented by a function of the information for identifying the MNO. In addition, for example, the BWP ID of the DL / UL BWP used (available) by the UE may also be represented by a function of the information for identifying the MNO.

[0150] The UE may also determine / judge information related to the DL / UL BWP based on the information used to identify the MNO.

[0151] The UE may determine the resources used by each MNO (eg, resources used by other MNOs (priority resources of other MNOs)) based on the information notified from the base station (eg, setting information).

[0152] For example, the UE receives information related to resources associated with other MNOs (or PLMN IDs) that are different from the MNO to which the terminal belongs. In addition, when at least one of the first UL transmission and the second UL transmission is scheduled to overlap with the priority resources of other MNOs in the time domain, the UE may also control whether the first UL transmission and the second UL transmission are sent / multiplexed / discarded / cancelled based on at least one of the priorities between MNOs, the priority of the first UL transmission, and the priority of the second UL transmission.

[0153] In the case where the UL transmission (or UL transmission resources) of other MNOs overlap in the priority resources of a certain MNO, the priority resources of a certain MNO may be prioritized and the UL transmission of other MNOs may be discarded / cancelled. Alternatively, in the case where the UL transmission (or UL resources) scheduled for the UE overlaps with the priority resources of other MNOs, control may be performed to discard / cancel the UL transmission if there is an indication from the base station (e.g., DCI / MAC CE / RRC).

[0154] <First embodiment>

[0155] In the first embodiment, UL transmission control is described when UL transmission of a certain MNO (or resources used in the UL transmission) overlaps with resources of another MNO (for example, priority resources of another MNO).

[0156] [Option 1-1]

[0157] The UE may also not assume that the priority resources of other MNOs overlap with UL transmission #1, and that UL transmission #2, which is different from UL transmission #1, overlaps with UL transmission #1 (for example, Figure 8 ). The base station may also control the scheduling of UL transmission so that the priority resources of a certain MNO do not overlap with the UL transmission #1 of the UE of another MNO, and the UL transmission #2 of the UL transmission #1 does not overlap with the UL transmission #1.

[0158] Figure 8 It shows that the priority resources of MNO#2 overlap with the first UL transmission #1 for UE#1 of MNO#1 in the time domain, and the first UL transmission #1 overlaps with the second UL transmission #2 for UE#1 in the time domain.

[0159] For example, UE#1 is scheduled to transmit an UL signal that overlaps with the priority resources of other MNOs ( Figure 8In the case of the first UL transmission #1 in UE#1, it is also possible not to assume that the second UL transmission #2 is scheduled to overlap with the UL transmission #1. Alternatively, in the case of the first UL transmission #1 and the second UL transmission #2 overlapping, UE#1 is also possible not to assume that the first UL transmission #1, the second UL transmission #2 and the priority resources of other MNOs overlap.

[0160] Alternatively, allow / support Figure 8 The situation shown, on the other hand, Figure 8 In the case shown, control can also be performed so that the transmission of other UEs (e.g., UE#2 of MNO#2) is not scheduled in the MNO#2 priority resources overlapping with the resources (time / frequency resources) of the first UL transmission #1. In this case, the base station can also control so that when the channels / signals of other MNOs are allocated in the priority resources of MNO#2, the channels / signals of MNO#2 are not allocated.

[0161] [Option 1-2]

[0162] When UL transmission #1 overlaps with priority resources of other MNOs, and UL transmission #2 different from UL transmission #1 overlaps with UL transmission #1, the UE may also control UL transmission (e.g., multiplexing / discarding) based on specific rules / specific procedures. For example, the UE may also apply at least one of the following options 1-2-1 to 1-2-2.

[0163] 《Option 1-2-1》

[0164] After performing conflict resolution based on intra-UE multiplexing / prioritization (Intra-UE multiplexing / prioritization), the UE performs priority processing between MNOs.

[0165] In the present disclosure, the conflict handling based on intra-UE multiplexing / priority (Intra-UE multiplexing / prioritization) can also apply the rules supported in the existing system (for example, before Rel.17) (for example, FIG. 3, Figure 4 ). Priority processing between MNOs can also give priority to the MNO corresponding to the priority resources and discard the resources / UL transmission of other MNOs.

[0166] Fig.9AIt shows that the priority resources of other MNOs overlap with UL transmission #1 (low), and UL transmission #2 (low) different from UL transmission #1 overlaps with UL transmission #1. Here, UL transmission #1 is equivalent to PUCCH set with low priority (low), and UL transmission #2 is equivalent to PUSCH set with low priority (low).

[0167] In such Fig.9A In the case of scheduled UL transmission #1 and UL transmission #2, the UE first multiplexes / drops UL transmission #1 / UL transmission #2 based on the priority of UL transmission #1 and UL transmission #2. The UE then performs: conflict handling of UL transmission based on multiplexing / priority within the UE and priority handling of other MNO resources (if any).

[0168] exist Fig.9A In the example, since UL Transmission #1 and UL Transmission #2 have the same priority (low), UL Transmission #1 corresponding to PUCCH is multiplexed / mapped to UL Transmission #2 corresponding to PUSCH. Thereafter, since the remaining UL Transmission #2 and MNO #2 priority resources do not overlap, the UE transmits UL Transmission #2 (or, no inter-MNO priority processing is performed).

[0169] Fig. 9B It shows that the priority resources of other MNOs overlap with UL transmission #1 (high), and UL transmission #2 (low) different from UL transmission #1 overlaps with UL transmission #1. Here, UL transmission #1 is equivalent to PUCCH with high priority (high), and UL transmission #2 is equivalent to PUSCH with low priority (low).

[0170] exist Fig. 9B In the example, since UL transmission #1 and UL transmission #2 have different priorities, UL transmission #2 (here PUSCH) with a lower priority is discarded. Thereafter, since the remaining UL transmission #1 overlaps with the priority resources of MNO #2, the UE discards UL transmission #1 (corresponding to MNO #1).

[0171] In addition, Fig. 9B , the case where all UL transmission #1 is discarded (or not transmitted) is shown, but the present invention is not limited thereto. The UE may also control to discard / not transmit a part of UL transmission #1 (or the resources of UL transmission #1) and transmit the remaining part. The discarded part of UL transmission #1 (or the resources of UL transmission #1) only needs to include at least a part overlapping with the priority resources of MNO #2.

[0172] 《Option 1-2-2》

[0173] After performing inter-MNO priority processing, the UE performs conflict processing based on intra-UE multiplexing / prioritization (Intra-UE multiplexing / prioritization).

[0174] Fig. 10A It shows that the priority resources of other MNOs overlap with UL transmission #1 (low), and UL transmission #2 (low) different from UL transmission #1 overlaps with UL transmission #1. Here, UL transmission #1 is equivalent to PUCCH set with low priority (low), and UL transmission #2 is equivalent to PUSCH set with low priority (low).

[0175] In such Fig. 10A As shown in the example, when UL transmission #1 and UL transmission #2 are scheduled, the UE first performs priority processing between resources of different MNOs, and then performs multiplexing / discarding between UL transmission #1 / UL transmission #2 (if any) based on the priorities of UL #1 and UL transmission #2.

[0176] exist Fig. 10A , UL Transmission #1 overlapping with the priority resource of MNO #2 is discarded. After that, conflict handling based on multiplexing / priority within the UE is performed, but here, UL Transmission #1 is discarded due to priority handling between MNOs, and there is no UL transmission overlapping with UL Transmission #2, so the UE transmits UL Transmission #2.

[0177] Fig. 10B It shows that the priority resources of other MNOs overlap with UL transmission #1 (high), and UL transmission #2 (low) different from UL transmission #1 overlaps with UL transmission #1. Here, UL transmission #1 is equivalent to PUCCH with high priority (high), and UL transmission #2 is equivalent to PUSCH with low priority (low).

[0178] exist Fig. 10B In the example, the first UL transmission #1 overlapping with the priority resource of MNO #2 is discarded. After that, conflict handling based on multiplexing / priority within the UE is performed, but here, UL transmission #1 is discarded due to priority handling between MNOs, and there is no UL transmission overlapping with UL transmission #2, so the UE transmits UL transmission #2.

[0179] In addition, Fig. 10A , Fig. 10B, the case where all UL transmission #1 overlapping with the priority resources of MNO#2 is discarded (or not transmitted), but the present invention is not limited to this. The UE may also perform control so as to discard / not transmit a part of UL transmission #1 (or the resources of UL transmission #1) and transmit the remaining part. The part of UL transmission #1 (or the resources of UL transmission #1) that is discarded only needs to include at least the part that overlaps with the priority resources of MNO#2.

[0180] In the case where a portion of UL transmission #1 is discarded, Fig. 10A In the process, after the inter-MNO priority processing, the remaining first UL transmission (PUCCH / UCI) can also be multiplexed to UL#2 (PUSCH).

[0181] In the first embodiment, which option is selected (or whether to apply) may be common or different according to the UL category / UL type. The UL category / UL type may also be classified by channel / signal category (PUSCH, PUCCH, SRS, PRACH), for example. Alternatively, the UL category / UL type may also be classified by UL transmission scheduled by DCI and UL transmission configured / activated by higher layer parameters.

[0182] Alternatively, the UE may be instructed via a high-layer parameter / DCI whether to apply conflict handling based on multiplexing / priority within the UE (intra-UE multiplexing / prioritization) and priority handling between MNOs. In this case, the base station may set / instruct the UE which processing to perform first, and may set / instruct the UE whether to apply conflict handling based on multiplexing / priority within the UE (intra-UE multiplexing / prioritization) or whether to apply priority handling between MNOs.

[0183] <Second embodiment>

[0184] In the second embodiment, in the case of supporting resource sharing between MNOs, cancellation control of UL transmission using cancellation indication information (for example, DCI) or setting of cancellation indication information between MNOs will be described.

[0185] The UE may also receive: first downlink control information (eg, DCI format 0_0 / 0_1 / 0_2) for scheduling UL transmission in shared resources supporting multiple MNOs and second downlink control information (eg, DCI format 2_4) indicating cancellation of UL transmission.

[0186] In this case, the UE may also determine whether to cancel the UL transmission based on a specific rule. The specific rule may be, for example, at least one of the priority of the UL transmission, the second downlink control information, and a condition set by a DCI / higher layer parameter.

[0187] The operation when a cancellation indication (eg, UL CI) is notified may be common among MNOs (applying common rules) (option 2-1) or independent among MNOs (supporting application of different rules) (option 2-2).

[0188] [Option 2-1]

[0189] The operation of each UE in response to the cancellation instruction (for example, the operation of each UE when the cancellation instruction is notified) is assumed to be the same among MNOs.

[0190] Regarding the cancellation instruction, the UE of each MNO performs at least one of the following options 2-1-1 to 2-1-5.

[0191] 《Option 2-1-1》

[0192] The UE may not assume that the cancellation instruction is notified through DCI (eg, UL CI) (or may not assume that the UL CI is set to receive it). For example, the UE operation based on the cancellation instruction may not be supported in the resources commonly set among MNOs.

[0193] Alternatively, the UE may perform control so that even if it receives DCI that indicates a cancellation, it does not follow the cancellation indication (or ignores the cancellation indication).

[0194] 《Option 2-1-2》

[0195] The UE may also control so as to cancel the UL transmission when the priority of the UL transmission to which the cancellation instruction is directed is low (see Fig.11 ).

[0196] exist Fig.11 , a case where UL transmission #1 (or resources for UL transmission #1) for MNO #1 and UL transmission #2 (or resources for UL transmission #2) for MNO #2 overlap with resources indicated by a cancellation indication is shown. When the priorities of UL transmission #1 and UL transmission #2 are set to low, each UE performs control so as not to transmit each UL transmission that is the subject of a cancellation indication.

[0197] Therefore, even when scheduling other UL transmissions (for example, with high priority) that overlap with resources for UL transmission #1 and UL transmission #2, the UL transmission can be canceled using a common cancellation indication between MNOs, and other UL transmissions with high priority can be appropriately performed.

[0198] 《Option 2-1-3》

[0199] The UE may perform control so as to cancel the UL transmission when the priority of the UL transmission that is the target of the cancellation instruction is high.

[0200] 《Option 2-1-4》

[0201] The UE may also control so that the UL transmission that is the object of the cancellation instruction is canceled regardless of the priority of the UL transmission. Each UE may also control so that when a cancellation instruction is indicated, the UL transmission is not performed regardless of the priority of the UL transmission that is the object of the cancellation instruction (even if the priority is high).

[0202] 《Option 2-1-5》

[0203] The UE may also determine whether to cancel the UL transmission based on the MNO priority of the resources scheduled for the UL transmission that is the subject of the cancellation indication (or taking into account the priority between MNOs). For example, in the case where the resources scheduled for the UL transmission that is the subject of the cancellation indication (e.g., the UL transmission corresponding to MNO#1) overlap with the priority resources of other MNOs (e.g., MNO#2), the cancellation indication may be followed. Option 2-1-5 may also be applied in combination with other options (e.g., options 2-1-2 to 2-1-4).

[0204] Metamorphosis

[0205] In addition, in the above-mentioned options 2-1-1 to 2-1-5, the case where the UL transmission itself (or all UL transmissions) that are the object of the cancellation indication are not transmitted is shown, but it is not limited to this. In the case where the resources indicated by the cancellation indication overlap with a part of the UL transmission (or the resources for UL transmission), the UL transmission may also be performed using the resources that do not overlap with the resources indicated by the cancellation indication. In this case, when the resources that do not overlap with the resources indicated by the cancellation indication (the remaining resources of the UL transmission) remain for a specific number (for example, X codewords) or more, the UL transmission may also be allowed.

[0206] [Option 2-2]

[0207] It is also possible to set the operation of each UE when the cancellation instruction is notified to be performed separately for each MNO (different for each MNO). The operation of each MNO (or the UE corresponding to each MNO) when the cancellation instruction is notified can also be controlled by the setting / instruction from the base station. The setting / instruction from the base station to each UE can also be performed using at least one of the higher layer parameters, MAC CE and DCI.

[0208] When the cancellation instruction is notified, the UE of each MNO performs at least one of the following options 2-2-1 to 2-2-4. The base station may also set / instruct which option to apply for each MNO (or the UE corresponding to each MNO) using at least one of the higher layer parameters, MAC CE, and DCI. That is, it supports the application of different options between MNOs.

[0209] 《Option 2-2-1》

[0210] In the case where it is set / indicated by a higher layer parameter / MAC CE / DCI, the UE may not assume that it is notified of the cancellation indication by the DCI for cancellation indication (e.g., UL CI) (or it may not assume that the UL CI is set to receive it). For example, it may be that the UE operation based on the cancellation indication is not supported in the resources commonly set between MNOs.

[0211] Alternatively, the UE may perform control so that even if it receives DCI that indicates a cancellation, it does not follow the cancellation indication (or ignores the cancellation indication).

[0212] 《Option 2-2-2》

[0213] When it is set / indicated by a higher layer parameter / MAC CE / DCI, the UE may also control to cancel the UL transmission when the priority of the UL transmission that is the object of the cancellation instruction is low (see Fig.12 ).

[0214] exist Fig.12 , the case where Option 2-2-2 is applied to UL transmission #1 (or resources for UL transmission #1) for MNO #1 is shown. When UL transmission #1 (or resources for UL transmission #1) overlaps with resources indicated by a cancellation indication and the priority of UL transmission #1 is set to low, the UE of MNO #1 controls not to transmit UL transmission #1 that is the subject of the cancellation indication.

[0215] 《Option 2-2-3》

[0216] When configured / indicated by higher layer parameters / MAC CE / DCI, the UE may perform control so as to cancel the UL transmission when the priority of the UL transmission that is the object of the cancellation instruction is high.

[0217] 《Option 2-2-4》

[0218] When set / indicated by a higher layer parameter / MAC CE / DCI, the UE may also control to cancel the UL transmission regardless of the priority of the UL transmission that is the object of the cancellation instruction. When a cancellation instruction is indicated, each UE may also control not to perform the UL transmission regardless of the priority of the UL transmission that is the object of the cancellation instruction (even if the priority is high).

[0219] In this way, it is also possible to support the application of different options between MNOs (between UEs with different MNOs).

[0220] Fig.13 The example shows a case where option 2-2-2 (cancel in case of low) is set / indicated to the UE of MNO#1, and option 2-2-1 (no cancellation instruction / not following the cancellation instruction) is set / indicated to the UE of MNO#2. In this case, even if UL transmission #1 low of MNO#1 and UL transmission #2 low of MNO#2 become the objects of cancellation instruction (for example, the resources specified by the cancellation instruction, UL transmission #1 and UL transmission #2 overlap), only UL transmission #1 is cancelled.

[0221] Fig.14 The example shows a case where option 2-2-4 (cancel regardless of priority) is set / indicated to the UE of MNO#1, and option 2-2-2 (cancel in the case of low) is set / indicated to the UE of MNO#2. In this case, even if UL transmission #1 (high) of MNO#1 and UL transmission #2 (high) of MNO#2 become the objects of the cancellation instruction (for example, the resources specified by the cancellation instruction, UL transmission #1 and UL transmission #2 overlap), only UL transmission #1 is canceled.

[0222] By supporting the use of different options between MNOs in this way, even when UL transmissions with the same priority overlap between MNOs, specific UL transmissions can be selectively canceled using one DCI for cancellation indication (or a common cancellation indication).

[0223] Furthermore, by supporting the application of different options between MNOs, even when UL transmissions of different priorities overlap between MNOs, control can be performed so that high-priority UL transmissions are canceled without canceling low-priority UL transmissions. Thus, in the priority resources of a certain MNO, it is possible to flexibly give priority to the UL transmission of that MNO (e.g., low) and selectively cancel the UL transmissions of other MNOs (e.g., high).

[0224] Metamorphosis

[0225] In addition, in the above-mentioned options 2-2-1 to 2-2-4, the case where the UL transmission itself (or all UL transmissions) that are the object of the cancellation indication are not transmitted is shown, but it is not limited to this. In the case where the resources indicated by the cancellation indication overlap with part of the UL transmission (or resources for UL transmission), the UL transmission may also be performed using resources that do not overlap with the resources indicated by the cancellation indication. In this case, when the resources that do not overlap with the resources indicated by the cancellation indication (the remaining resources of the UL transmission) remain for a specific number (for example, X codewords) or more, the UL transmission may also be allowed.

[0226] In addition, which option is selected (or whether to apply) may be common or different according to the UL category / UL type. The UL category / UL type may also be classified by channel / signal category (PUSCH, PUCCH, SRS, PRACH), for example. Alternatively, the UL category / UL type may also be classified by UL transmission scheduled by DCI and UL transmission configured / activated by higher layer parameters.

[0227] Furthermore, in the present disclosure, the frequency for resource sharing (common frequency) may also be used only for a specific transmission direction / link.

[0228] The specific transmission direction / link may be, for example, at least one of DL, UL, and auxiliary UL.

[0229] In the present disclosure, a common frequency may also be used only for a specific channel / signal.

[0230] In the present disclosure, common frequencies may also be used in certain scenarios.

[0231] This specific scenario may be, for example, a scenario in which a base station is shared and communication is performed with UEs corresponding to respective MNOs (see Fig.15A ).

[0232] This specific scenario may be, for example, a scenario in which a base station is not shared and communication is performed with UEs corresponding to different MNOs (see Fig. 15B ).

[0251] (Wireless Communication System)

[0252] Hereinafter, a configuration of a wireless communication system according to an embodiment of the present disclosure will be described. In the wireless communication system, communication is performed using any one of the wireless communication methods according to the above-mentioned embodiments of the present disclosure or a combination thereof.

[0253] Fig.16 1 is a diagram showing an example of a schematic structure of a wireless communication system involved in one embodiment. The wireless communication system 1 may also be a system that implements communication using Long Term Evolution (LTE) standardized by the Third Generation Partnership Project (3GPP), the fifth generation mobile communication system New Radio (5G NR), and the like.

[0257] The wireless communication system 1 may also include a base station 11 that forms a macro cell C1 with a relatively wide coverage, and a base station 12 (12a-12c) that is configured in the macro cell C1 and forms a small cell C2 that is narrower than the macro cell C1. The user terminal 20 may also be located in at least one cell. The configuration and number of each cell and user terminal 20 are not limited to the method shown in the figure. Hereinafter, when the base stations 11 and 12 are not distinguished, they are collectively referred to as base stations 10.

[0258] The user terminal 20 may be connected to at least one of the plurality of base stations 10. The user terminal 20 may use at least one of carrier aggregation (CA) using a plurality of component carriers (CC) and dual connectivity (DC).

[0259] Each CC may also be included in at least one of the first frequency band (Frequency Range 1 (FR1)) and the second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may also be included in FR1, and the small cell C2 may also be included in FR2. For example, FR1 may be a frequency band below 6 GHz (below 6 GHz (sub-6 GHz)), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). In addition, the frequency bands and definitions of FR1 and FR2 are not limited to these. For example, FR1 may also be equivalent to a frequency band higher than FR2.

[0260] Furthermore, the user terminal 20 may perform communication in each CC using at least one of time division duplex (TDD) and frequency division duplex (FDD).

[0261] Multiple base stations 10 may also be connected via wired (e.g., optical fiber based on Common Public Radio Interface (CPRI)), X2 interface, etc.) or wireless (e.g., NR communication). For example, when NR communication between base stations 11 and 12 is used as a backhaul, the base station 11 equivalent to the upper station may also be referred to as an Integrated Access Backhaul (IAB) donor, and the base station 12 equivalent to a relay station (relay) may also be referred to as an IAB node.

[0263] The user terminal 20 may also be a terminal that supports at least one of communication modes such as LTE, LTE-A, and 5G.

[0264] In the wireless communication system 1, a wireless access method based on orthogonal frequency division multiplexing (OFDM) may be used. For example, in at least one of the downlink (DL) and the uplink (UL), cyclic prefix OFDM (CP-OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), etc. may be used.

[0265] The radio access scheme may also be referred to as a waveform. In addition, in the wireless communication system 1, other radio access schemes (for example, other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the radio access schemes for UL and DL.

[0266] As downlink channels, the wireless communication system 1 may use a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20, a broadcast channel (Physical Broadcast Channel (PBCH))), a downlink control channel (Physical Downlink Control Channel (PDCCH)), etc.

[0268] User data, high-layer control information, system information block (SIB), etc. are transmitted through PDSCH. User data, high-layer control information, etc. can also be transmitted through PUSCH. In addition, master information block (MIB) can also be transmitted through PBCH.

[0269] The lower layer control information may also be transmitted via the PDCCH. The lower layer control information may include, for example, downlink control information (Downlink Control Information (DCI)) including scheduling information of at least one of the PDSCH and the PUSCH.

[0270] In addition, the DCI for scheduling the PDSCH may also be referred to as DL allocation, DL DCI, etc., and the DCI for scheduling the PUSCH may also be referred to as UL grant, UL DCI, etc. In addition, the PDSCH may also be replaced by DL data, and the PUSCH may also be replaced by UL data.

[0271] In the detection of PDCCH, the control resource set (CORESET) and the search space can also be used. CORESET corresponds to the resources for searching DCI. The search space corresponds to the search area and search method of PDCCH candidates. A CORESET can also be associated with one or more search spaces. The UE can also monitor the CORESET associated with a search space based on the search space setting.

[0272] A search space may also correspond to a PDCCH candidate corresponding to one or more aggregation levels. One or more search spaces may also be referred to as a search space set. In addition, the "search space", "search space set", "search space setting", "search space set setting", "CORESET", "CORESET setting" and the like in the present disclosure may also be rewritten mutually.

[0273] Uplink control information (uplink control information (UCI)) including at least one of channel state information (CSI), delivery confirmation information (e.g., also known as hybrid automatic repeat request confirmation (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR) can also be transmitted through PUCCH. The random access preamble used to establish a connection with a cell can also be transmitted through PRACH.

[0274] In the present disclosure, downlink, uplink, etc. may be expressed without the word “link.” In addition, various channels may be expressed without the word “physical” at the beginning.

[0275] In the wireless communication system 1, a synchronization signal (Synchronization Signal (SS)), a downlink reference signal (Downlink Reference Signal (DL-RS)), etc. can also be transmitted. As DL-RS, in the wireless communication system 1, a cell-specific reference signal (Cell-specific Reference Signal (CRS)), a channel state information reference signal (Channel State Information Reference Signal (CSI-RS)), a demodulation reference signal (DeModulation Reference Signal (DMRS)), a positioning reference signal (Positioning Reference Signal (PRS)), a phase tracking reference signal (Phase Tracking Reference Signal (PTRS)), etc. can also be transmitted.

[0276] The synchronization signal may be, for example, at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). A signal block including SS (PSS, SSS) and PBCH (and DMRS for PBCH) may also be referred to as SS / PBCH block, SS block (SSB), etc. In addition, SS, SSB, etc. may also be referred to as reference signals.

[0277] In addition, in the wireless communication system 1, as an uplink reference signal (Uplink Reference Signal (UL-RS)), a measurement reference signal (Sounding Reference Signal (SRS)), a demodulation reference signal (DMRS), etc. can also be transmitted. In addition, DMRS can also be called a user terminal specific reference signal (UE-specific Reference Signal).

In addition, the control unit 210, the transmitting / receiving unit 220, and the transmitting / receiving antenna 230 may each be provided with one or more.

[0300] In addition, in this example, the functional blocks of the characteristic parts in this embodiment are mainly shown, and it is also conceivable that the user terminal 20 also has other functional blocks required for wireless communication. Part of the processing of each unit described below may be omitted.

[0307] The transmitting and receiving unit 220 may also use digital beamforming (eg, precoding), analog beamforming (eg, phase rotation), etc. to form at least one of a transmitting beam and a receiving beam.

[0308] The sending and receiving unit 220 (sending processing unit 2211) can also perform PDCP layer processing, RLC layer processing (for example, RLC retransmission control), MAC layer processing (for example, HARQ retransmission control), etc. on the data, control information, etc. obtained from the control unit 210 to generate a bit string to be sent.

[0310] In addition, whether to apply DFT processing may also be based on the setting of transform precoding. For a certain channel (e.g., PUSCH), when transform precoding is valid (enabled), the transmitting and receiving unit 220 (transmitting processing unit 2211) may also perform DFT processing as the above-mentioned transmission processing in order to transmit the channel using a DFT-s-OFDM waveform.

[0317] In the case where resources overlap with the first UL transmission in the time domain, the control unit 210 may also not assume that the first UL transmission overlaps with the second UL transmission in the time domain.

The transmitting and receiving unit 120 (220) may also be realized by physically or logically separating the transmitting unit 120a (220a) and the receiving unit 120b (220b).

The output device 1006 is an output device that implements output to the outside (e.g., a display, a speaker, a light emitting diode (LED) lamp, etc.). In addition, the input device 1005 and the output device 1006 may also be an integrated structure (e.g., a touch panel).

[0339] A time slot may also be composed of one or more symbols (Orthogonal Frequency Division Multiplexing (OFDM) symbols, Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols, etc.) in the time domain. In addition, a time slot may also be a time unit based on a parameter set.

[0340] A time slot may also include multiple mini-slots. Each mini-slot may also be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may also be composed 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 a PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may also be referred to as a PDSCH (PUSCH) mapping type B.

[0341] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols may also be referred to by their respective names. In addition, time units such as frames, subframes, time slots, mini-time slots, and symbols in the present disclosure may also be replaced with each other.

[0342] For example, a subframe may be referred to as a TTI, a plurality of consecutive subframes may be referred to as a TTI, and a time slot or a mini time slot may be referred to as a TTI. That is, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. In addition, the unit representing a TTI may be referred to as a time slot, a mini time slot, etc. instead of a subframe.

[0343] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station schedules each user terminal to allocate wireless resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) in TTI units. In addition, the definition of TTI is not limited to this.

[0344] TTI may also be a transmission time unit for a data packet (transport block), a code block, a code word, etc. that has been channel-coded, and may also be a processing unit for scheduling, link adaptation, etc. In addition, when 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.

[0345] In addition, when a time slot or a mini time slot is called TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) can also be the minimum time unit of scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit of scheduling can also be controlled.

[0346] A TTI having a time length of 1 ms may also be referred to as a normal TTI (TTI in 3GPP Rel.8-12), a standard TTI, a long TTI, a normal subframe, a standard 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 mini time slot, a sub time slot, a time slot, etc.

[0347] In addition, a long TTI (e.g., normal TTI, subframe, etc.) can also be rewritten as a TTI with a time length exceeding 1 ms, and a short TTI (e.g., shortened TTI, etc.) can also be rewritten as a TTI with a TTI length shorter than that of the long TTI and longer than 1 ms.

[0348] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers (subcarriers) in the frequency domain. The number of subcarriers included in an RB may also be the same regardless of the parameter set, for example, 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0349] In addition, an RB may also include one or more symbols in the time domain, and may also be the length of a slot, a mini-slot, a subframe, or a TTI. A TTI, a subframe, etc. may also be composed of one or more resource blocks, respectively.

[0350] In addition, one or more RBs may also be referred to as a physical resource block (Physical RB (PRB)), a sub-carrier group (Sub-Carrier Group (SCG)), a resource element group (Resource Element Group (REG)), a PRB pair, an RB pair, etc.

[0351] In addition, a resource block may be composed of one or more resource elements (RE). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0352] Bandwidth Part (BWP) (also referred to as partial bandwidth, etc.) may also represent a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, common RBs may also be identified by the index of the RB relative to the common reference point of the carrier. PRBs may also be defined in a BWP and numbered within the BWP.

[0353] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). For a UE, one or more BWPs may be configured in one carrier.

[0354] At least one of the set BWPs may be activated, and the UE may not assume that it will transmit or receive a specific signal / channel other than the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may also be rewritten as "BWP".

[0355] In addition, the above-mentioned structures such as radio frames, subframes, time slots, mini-time slots and symbols are only examples. For example, the number of subframes included in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots included in a time slot, the number of symbols and RBs included in a time slot or mini-time slot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, and the cyclic prefix (CP) length can be changed in various ways.

[0356] In addition, the information, parameters, etc. described in the present disclosure may be represented by absolute values, relative values ​​relative to a specific value, or other corresponding information. For example, wireless resources may also be indicated by a specific index.

[0357] In the present disclosure, the names used for parameters, etc. are not limiting in all respects. Furthermore, the mathematical formulas, etc. using these parameters may be different from those explicitly disclosed in the present disclosure. Various channels (PUCCH, PDCCH, etc.) and information elements can be identified by any suitable names, and therefore, the various names assigned to these various channels and information elements are not limiting in all respects.

[0358] Information, signals, etc. described in this disclosure may also be represented using any of a variety of different techniques. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be mentioned throughout the above description may also be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0359] Furthermore, information, signals, etc. can be output in at least one of the following directions: from a higher layer (upper layer) to a lower layer (lower layer), and from a lower layer to a higher layer. Information, signals, etc. can also be input and output via multiple network nodes.

[0360] The input and output information, signals, etc. may be stored in a specific location (e.g., a memory), or may be managed using a management table. The input and output information, signals, etc. may be overwritten, updated, or appended. The output information, signals, etc. may also be deleted. The input information, signals, etc. may also be sent to other devices.

[0361] The notification of information is not limited to the methods / implementations described in the present disclosure, and may also be performed by other methods. For example, the notification of information in the present disclosure may also be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information (DCI))), uplink control information (Uplink Control Information (UCI))), high-layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB)), System Information Block (SIB)), etc.), Medium Access Control (MAC) signaling), other signals or a combination thereof.

[0362] In addition, physical layer signaling may also be referred to as layer 1 / layer 2 (Layer 1 / Layer 2 (L1 / L2)) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. In addition, RRC signaling may also be referred to as an RRC message, such as an RRC connection establishment (RRC Connection Setup) message, an RRC connection reconstruction (RRC Connection Reconfiguration) message, etc. In addition, MAC signaling may also be notified using, for example, a MAC control element (MACControl Element (CE)).

[0363] Furthermore, notification of specific information (eg, notification of “it is X”) is not limited to explicit notification, but may be performed implicitly (eg, by not notifying the specific information or by notifying other information).

[0364] The determination can be made by a value represented by a bit (0 or 1), by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a specific value).

[0365] Whether software is called software, firmware, middle-ware, microcode, hardware description language, or other names, it should be broadly interpreted as meaning instructions, instruction sets, code, code segments, program code, program, sub-program, software modules, applications, software applications, software packages, routines, sub-routines, objects, executable files, execution threads, procedures, functions, etc.

[0366] In addition, software, instructions, information, etc. may also be sent and received via a transmission medium. For example, when software is sent from a website, server, or other remote source using at least one of wired technology (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), etc.) and wireless technology (infrared, microwave, etc.), at least one of these wired technology and wireless technology is included in the definition of transmission medium.

[0367] The terms "system" and "network" used in the present disclosure can be used interchangeably. "Network" may also refer to a device (eg, a base station) included in the network.

[0370] A base station can accommodate one or more (for example, three) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, and each smaller area can also provide communication services through a base station subsystem (for example, a small base station for indoor use (Remote Radio Head (RRH))). Terms such as "cell" or "sector" refer to a part or the entirety of the coverage area of ​​at least one of a base station and a base station subsystem that provides communication services within the coverage area.

[0371] In the present disclosure, the base station sending information to the terminal and the base station instructing the terminal to perform control / operation based on the information may be rewritten to each other.

[0372] In the present disclosure, terms such as “mobile station (MS)”, “user terminal”, “user device (User Equipment (UE))”, and “terminal” can be used interchangeably.

In addition, the driving assistance system unit 64 sends and receives various information via the communication module 60 to realize the driving assistance function or the autonomous driving function.

[0384] The communication module 60 can communicate with the microprocessor 61 and the structural elements of the vehicle 40 via the communication port 63. For example, the communication module 60 transmits and receives data (information) between the drive unit 41, the steering unit 42, the accelerator pedal 43, the brake pedal 44, the shift lever 45, the left and right front wheels 46, the left and right rear wheels 47, the axle 48, the microprocessor 61 and the memory (ROM, RAM) 62 in the electronic control unit 49, and the various sensors 50-58 provided in the vehicle 40 via the communication port 63.

[0385] The communication module 60 is a communication device that can be controlled by the microprocessor 61 of the electronic control unit 49 and can communicate with an external device. For example, various information is sent and received with the external device via wireless communication. The communication module 60 can also be located either inside or outside the electronic control unit 49. The external device can also be, for example, the above-mentioned base station 10, user terminal 20, etc. In addition, the communication module 60 can also be, for example, at least one of the above-mentioned base station 10 and user terminal 20 (it can also function as at least one of the base station 10 and user terminal 20).

[0386] The communication module 60 may also transmit at least one of the signals from the various sensors 50-58 input to the electronic control unit 49, information obtained based on the signals, and information based on input from the outside (user) obtained via the information service unit 59 to an external device via wireless communication.

[0389] In addition, the base station in the present disclosure may also be rewritten as a user terminal. For example, the various methods / implementations of the present disclosure may also be applied to a structure in which the communication between a base station and a user terminal is rewritten as communication between multiple user terminals (for example, it may also be referred to as device-to-device (D2D)), vehicle-to-everything (V2X), etc.). In this case, it may also be set as a structure in which the user terminal 20 has the functions possessed by the above-mentioned base station 10. In addition, terms such as "uplink" and "downlink" may also be rewritten as terms corresponding to inter-terminal communication (for example, "sidelink"). For example, uplink channels, downlink channels, etc. may also be rewritten as sidelink channels.

[0390] Likewise, the user terminal in the present disclosure may be rewritten as a base station. In this case, the base station 10 may have the functions of the user terminal 20 described above.

[0391] In the present disclosure, operations are assumed to be performed by a base station, and sometimes by its upper node depending on the situation. Obviously, in a network including one or more network nodes having a base station, various operations performed for communication with a terminal can be performed by a base station, one or more network nodes other than the base station (for example, Mobility Management Entity (MME)), Serving-Gateway (S-GW), etc., but not limited to these), or a combination thereof.

[0392] The various methods / implementations described in this disclosure may be used individually or in combination, and may be used in a switched manner as the method is executed.

In addition, multiple systems can also be applied in combination (for example, LTE or LTE-A, combination with 5G, etc.).

[0394] The phrase “based on” used in the present disclosure does not mean “based only on” unless otherwise specified. In other words, the phrase “based on” means both “based only on” and “based at least on”.

[0395] Any reference to an element using the terms "first", "second", etc. used in this disclosure does not fully define the amount or order of these elements. These terms can be used in this disclosure as a convenient method to distinguish between two or more elements. Therefore, reference to the first and second elements does not mean that only two elements can be used or that the first element must take precedence over the second element in some form.

[0396] The term "determining" used in the present disclosure may include a variety of operations. For example, "determining" may also refer to situations where judging, calculating, computing, processing, deriving, investigating, looking up (for example, searching in a table, database or other data structure), ascertaining, etc. are regarded as performing "determining".

[0397] In addition, "judgment (decision)" may also be a situation where receiving (for example, receiving information), sending (for example, sending information), input (input), output (output), accessing (for example, accessing data in a memory), etc. are regarded as making a "judgment (decision)".

[0398] In addition, "judgment (decision)" can also refer to situations where resolving, selecting, choosing, establishing, comparing, etc. are considered as "judgment (decision)". That is, "judgment (decision)" can also refer to situations where some actions are considered as "judgment (decision)".

[0399] In addition, "judge (decide)" can also be rewritten as "assuming (assuming)", "expecting (expecting)", "considering (considering)" and so on.

[0401] The terms "connected", "coupled", or all their variations used in this disclosure refer to all direct or indirect connections or combinations between two or more elements, and may include the situation where one or more intermediate elements exist between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be physical, logical, or a combination thereof. For example, "connection" may also be rewritten as "access".

[0402] In the present disclosure, when two elements are connected, it is possible to consider being "connected" or "combined" to each other using one or more wires, cables, printed electrical connections, etc., as well as being "connected" or "combined" to each other using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, light (both visible and invisible) region, etc. as several non-limiting and non-inclusive examples.

[0403] In the present disclosure, the term "A is different from B" may also mean "A and B are different from each other". In addition, the term may also mean "A and B are different from C, respectively". The terms "separate" and "combined" may also be interpreted in the same manner as "different".

[0404] When the terms “include,” “including,” and variations thereof are used in the present disclosure, these terms have an inclusive meaning, similar to the term “comprising.” Furthermore, the term “or” used in the present disclosure does not have an exclusive OR meaning.

[0405] In the present disclosure, when an article is added by translation like a, an, and the in English, for example, the present disclosure may also include a case where the noun following the article is in plural form.

[0406] In the present disclosure, "below", "less than", "above", "more than", "equal to", etc. may also be rephrased with each other. Furthermore, in the present disclosure, terms meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. are not limited to the original level, comparative level and superlative level, but may also be rephrased with each other. Furthermore, in the present disclosure, terms meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. are not limited to the original level, comparative level and superlative level, but may also be rephrased with each other as expressions with "ith" (i is an arbitrary integer) attached thereto (for example, "highest" may also be rephrased with "i-th highest").

[0407] In the present disclosure, “of,” “for,” “regarding,” “related to,” “associated with,” etc. may be replaced by each other.

[0408] The invention involved in the present disclosure has been described in detail above, but it is obvious to those skilled in the art that the invention involved in the present disclosure is not limited to the embodiments described in the present disclosure.
