[0007] Problems to be solved by the invention

[0008] In future wireless communication systems (for example, Rel. 18 and later), resource sharing is being studied for the purpose of improving the efficiency of frequency band utilization (existing frequency bands and new high-frequency bands).

[0025] (IAB Node)

[0026] The use of IAB (Integrated Access Backhaul) technology, which uses NR communication as a backhaul between base stations (or between base stations and relay stations), is being studied. In particular, it is expected that by using IAB of NR communication using millimeter waves, the coverage area can be expanded at a low cost.

[0027] The IAB node may also have at least one function of DU (Distribution Unit), CU (Central Unit), MT (Mobile Termination), etc. Therefore, the IAB node having the function of DU / CU may also function as a base station, and the IAB node having the function of MT (IAB node MT) may also function as a user terminal (user device (User Equipment (UE)), terminal).

[0028] In addition, IAB may also be referred to as wireless backhaul, etc. The link between nodes using IAB may also be referred to as a backhaul (BH) link. The link between an IAB node and a UE may also be referred to as an access link. An IAB node may also use communications utilizing NR in a backhaul link. In an access link, an IAB node may use communications utilizing NR or communications based on other RATs (Radio Access Technologies).

[0029] By introducing IAB, since the base station can use the same frequency for backhaul and for UE access simultaneously or in a switching manner, it is expected that the frequency utilization efficiency will be improved. For example, the backhaul link and the access link may be multiplexed using at least one of time division multiplexing (TDM), frequency division multiplexing (FDM), and space division multiplexing (SDM).

[0030] Figure 1 is a diagram showing an example of the structure of an IAB. In this example, three nodes (network nodes) AC are shown. Node A is connected to the core network via a wired backhaul (e.g., an optical fiber network). A node connected to the core network via a wired backhaul may also be referred to as an IAB donor.

[0031] A higher-level IAB node or IAB donor may also be referred to as a parent IAB node (parent IAB node / parentnode IAB), a parent node, an upper node, an upper IAB node, etc. A lower-level IAB node may also be referred to as a child IAB node (child IAB node / child node IAB), a child node, a lower node, etc. Here, upper may also mean at least one (with fewer hops) that is closer to a base station (e.g., gNB), a wired backhaul, a core network, etc. In the following, network nodes including IAB nodes and IAB donors are referred to as nodes.

[0032] For example, in Figure 1 In the example of , node A is the parent node of node B, and node B is the parent node of node C. In this way, multiple backhaul hops may also be included in IAB. In addition, nodes AC can communicate with UEs AC respectively via access links.

[0033] When a node has the function of an upper node, the node can accommodate a lower IAB node (connected to the lower IAB node via a BH link) and can accommodate a UE (connected to the UE via an access link). The upper node can also implement the scheduling of the lower IAB node and can also control the transmission or reception of the lower IAB node.

[0034] In the case where a certain IAB node does not have the function of an upper node (for example, supporting the operation as a base station), the IAB node cannot accommodate lower IAB nodes but can only accommodate UEs.

[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 frequency band utilization (existing frequency bands and new high-frequency bands).

[0037] In resource sharing, a radio access network (RAN) can be shared among multiple operators, the network (NW, such as base stations) investment cost can be divided among each operator, and multiple base stations can be installed.

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

[0039] In addition, by having multiple operators share distributed nodes (e.g., distributed units (DU)) / aggregation nodes (e.g., central units (CU))) (e.g., shared hardware infrastructure), the equipment costs can be shared by the multiple operators.

[0040] Furthermore, by sharing frequency / antenna units (eg, radio units (RU)) among multiple operators, it is possible to improve resource utilization efficiency, for example, other operators can use resources that are not being used by a certain operator.

[0041] Figure 2A-2D This is a diagram showing an example of network sharing.

[0042] Figure 2A An example of site sharing is shown in FIG. Figure 2A As shown, in site sharing, antennas / sites are shared by multiple operators. On the other hand, multiple operators are independent of each other in terms of service platform, HSS (Home Subscriber Server) / HLR (Home Location Register), Core Network (CN) Packet Switching (PS), base stations, and cells / frequencies.

[0043] Figure 2B An example of MORAN (Multi Operator RAN) is shown. Figure 2BAs shown, in MORAN, multiple operators share a part of the base station (e.g., the hardware of the base station) in addition to the antenna / site. On the other hand, multiple operators are independent of each other in terms of service platform, HSS / HLR, CN PS, other parts of the base station (e.g., the software of the base station), and cell / frequency.

[0044] Figure 2C An example of MOCN (Multi Operator Core Network) is shown. Figure 2C As shown, in MOCN, multiple operators share base stations and cells / frequencies. On the other hand, multiple operators are independent of each other in terms of service platform, HSS / HLR, and CN PS.

[0045] Figure 2D An example of GWCN (Gateway Core Network) is shown. Figure 2D As shown, in GWCN, multiple operators share CN PS, base stations and cells / frequencies. On the other hand, multiple operators are independent of each other in terms of service platform and HSS / HLR.

[0046] In MOCN / GWCN, since multiple operators share cells, it is preferable to be able to change settings for each operator (for example, for each ID (PLMN ID) related to a public land mobile communication network (Public Land Mobile Network (PLMN))).

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

[0048] On the other hand, for terminals in the RRC connected state (user terminals, User Equipment (UE)), operator-specific settings can be set as RRC configurations according to the PLMN ID of the terminal. Specifically, in resource sharing, if it is desired that only terminals of a specific operator can use a portion of the time resources of a shared cell, it is possible to configure terminals of other operators not to use that portion of the time resources.

[0049] In addition, the sharing of IAB nodes among multiple operators is also being studied. In the present disclosure, the IAB nodes shared among multiple operators may also be referred to as common IAB nodes or shared IAB nodes.

[0050] Consider a scenario where a common IAB node is connected to multiple base stations (base stations corresponding to PLMN IDs).

[0051] In this case, it is assumed that at least one of the configuration for the IAB node and the report by the IAB node requires association with the PLMN ID.

[0052] However, when the IAB node is shared among multiple operators, the association between setting / reporting and PLMN ID has not been sufficiently studied. If this study is insufficient, flexible communication operation cannot be performed for each operator, and there is a concern that improvement in communication quality may be inhibited.

[0053] Therefore, the inventors of the present invention have come up with a method for applying / setting flexible operation strategies / parameters between operators in order to achieve efficient office deployment / frequency utilization through resource sharing.

[0054] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The wireless communication methods according to the embodiments may be applied individually or in combination.

[0055] In the present disclosure, "A / B" and "at least one of A and B" may be replaced with each other. In addition, in the present disclosure, "A / B / C" may also mean "at least one of A, B, and C".

[0056] In the present disclosure, activate, deactivate, indicate (or specify), select, configure, update, determine, etc. may also be mutually rewritten. In the present disclosure, support, control, controllable, operate, and operate may also be mutually rewritten.

[0057] In the present disclosure, Radio Resource Control (RRC), RRC parameters, RRC messages, high-layer parameters, fields, Information Element (IE), settings, etc. may also be overwritten with each other. In the present disclosure, Medium Access Control (MAC) control elements (MAC Control Element (CE)), update commands, activation / deactivation commands, etc. may also be overwritten with each other.

[0058] In the present disclosure, the higher layer signaling may be, for example, any one of Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, etc., or a combination thereof.

[0059] In the present disclosure, MAC signaling may also use, for example, MAC Control Element (MACCE), MAC Protocol Data Unit (MAC Protocol Data Unit (PDU)), etc. Broadcast information may also be, for example, Master Information Block (MIB), System Information Block (SIB), minimum system information (Remaining Minimum System Information (RMSI)), Other System Information (Other System Information (OSI)), etc.

[0060] In the present disclosure, the physical layer signaling may be, for example, downlink control information (Downlink Control Information (DCI)), uplink control information (Uplink Control Information (UCI)), etc.

[0061] In the present disclosure, index, identifier (ID), indicator, resource ID, etc. may also be mutually overwritten. In the present disclosure, sequence, list, set (set), group, cluster, subset, etc. may also be mutually overwritten.

[0062] In the present disclosure, ignore, discard, suspend, cancel, puncture, rate match, postpone, etc. can also be rewritten to each other.

[0063] In the present disclosure, a specific ID, an ID related to a Public Land Mobile Network (PLMN), a PLMN ID, a PLMN identifier, a PLMN identity, PLMN identifier information, PLMN identity information, PLMN ID information, information for identifying an operator, an ID for identifying an operator, an ID for each operator, a group ID, a PLMN group ID, etc. may also be overwritten with each other.

[0064] In the present disclosure, PLMN, operator, operator (operator), operator policy, settings for each operator, settings for each operator (operator), etc. can also be rewritten.

[0065] In the present disclosure, wireless communication device, device, IAB, IAB node, IAB node MT, IAB-MT, IAB node DU, IAB-DU, terminal, UE, mobile station, and base station may also be rewritten mutually.

[0066] (Wireless Communication Method)

[0067] Hereinafter, in the present disclosure, the PLMN ID is taken as an example as a specific ID, but the name of the specific ID is not limited thereto.

[0068] In the present disclosure, a specific parameter (RRC parameter) may also be associated with a specific ID (eg, PLMN ID).

[0069] For this association, parameters related to the specific ID may also be included in the specific parameters.

[0070] For this association, other parameters included in the specific parameter may include parameters related to the specific ID.

[0071] For this association, the new parameters included in the specific parameters can also be associated with the parameters related to the specific ID. The new parameters can also include parameters related to the specific ID.

[0072] In the present disclosure, a description indicating the version that specifies the RRC parameter may be added to each RRC parameter.

[0073] This record may be, for example, "-r18". The RRC parameters with this record and the RRC parameters without this record may be the same parameters. For example, prach-ConfigurationPeriodScaling-IAB and prach-ConfigurationPeriodScaling-IAB-r18 may also mean the same parameter. In addition, "-r18" is just an example and can be rewritten as any record (for example, "-r17" / "-r19", etc.), or the record may not be attached to the RRC parameters.

[0074] <First embodiment>

[0075] It is also possible to support separate (independent) settings related to the synchronization signal for each specific ID (for example, PLMN ID).

[0076] The configuration related to the synchronization signal may be, for example, at least one of a synchronization signal block (SSB) transmission configuration (SSB Transmission Configuration (STC)) and an SSB-based measurement timing configuration (SSB-based Measurement Timing Configuration (SMTC)).

[0077] It is also possible to set an independent STC / SMTC for each specific ID for a wireless communication device (for example, an IAB node).

[0078] The STC may also be set by a specific parameter. For example, the specific parameter may also be IAB STC information (eg, IAB STC-Info) / IAB STC information list (eg, IAB STC-Info List).

[0079] Parameters related to a specific ID (eg, PLMN ID) may also be associated with IAB STC information (IAB STC-Info) / IAB STC information list (IAB STC-Info List).

[0080] For example, the IAB STC information (IAB STC-Info) / IAB STC information list (IAB STC-Info List) may also include parameters related to a specific ID (eg, PLMN ID).

[0081] For example, at least one of the specific parameters in the IAB STC information (IAB STC-Info) / IAB STC information list (IAB STC-Info List) may also be associated with a parameter associated with a specific ID (eg, PLMN ID).

[0082] The specific parameter may be, for example, at least one of the following: a parameter related to SSB frequency information (SSB center frequency information) (for example, SSB frequency information (SSB Frequency Info)), a parameter related to SSB subcarrier spacing (for example, SSB subcarrier spacing (SSB Subcarrier Spacing)), a parameter related to SSB transmission period (for example, SSB transmission period (SSB Transmission Periodicity)), a parameter related to SSB transmission timing offset (SSB transmission timing offset expressed in half-frame numbers) (for example, SSB transmission timing offset (SSB Transmission TimingOffset)), and a parameter related to SSB transmission bitmap (for example, SSB transmission bitmap (SSB Transmission Bitmap)).

[0083] Figure 3 FIG. 1 is a diagram showing an example of the setting of the STC according to the first embodiment. Figure 3 In the example shown, the IAB STC information (IAB STC-Info) includes information related to the PLMN ID (PLMN ID).

[0084] Use as Figure 3 The information elements shown enable the IAB node to determine the STC set for each PLMN ID.

[0085] In addition, Figure 3 In the example shown, an example is shown in which a parameter indicating a PLMN ID is included in the IAB STC-Info, but the PLMN ID may be associated with a specific parameter (at least one of the above-mentioned specific parameters) included in the IAB STC-Info.

[0086] SMTC may also be set by a specific parameter. For example, the specific parameter may also be SSB-MTC information.

[0087] The SSB-MTC information may also be a parameter (eg, SSB-MTC3) for setting the measurement timing of the synchronization signal corresponding to the IAB node MT (IAB MT). The parameter may also be a parameter used by the IAB node to discover other IAB nodes / IAB donor DUs.

[0088] Parameters related to a specific ID (eg, PLMN ID) may also be associated with SSB-MTC information (eg, SSB-MTC3).

[0089] For example, SSB-MTC information (eg, SSB-MTC3) may also include parameters related to a specific ID (eg, PLMN ID).

[0090] For example, at least one of the specific parameters within the SSB-MTC information (eg, SSB-MTC3) may also be associated with a parameter associated with a specific ID (eg, PLMN ID).

[0091] The specific parameter may also be at least one of the following: a parameter indicating the period of the measurement window for receiving the SS / PBCH block (e.g., duration), a parameter indicating a list of physical cell IDs (e.g., pci-List), a parameter indicating the period and offset of the measurement window for receiving the SS / PBCH block (e.g., periodicityAndOffset), and a parameter indicating a set of SS blocks within the SMTC measurement period (e.g., ssb-ToMeasure).

[0092] Figure 4 FIG. 1 is a diagram showing an example of the setting of the SMTC according to the first embodiment. Figure 4 In the example shown, the SSB-MTC information (SSB-MTC3) includes information related to the PLMN ID (plmn-id).

[0093] Use as Figure 4 The information elements shown enable the IAB node to determine the SMTC set for each PLMN ID.

[0094] In addition, Figure 4 In the example shown, an example is shown in which a parameter representing the PLMN ID is included in SSB-MTC3, but the PLMN ID can also be associated with a specific parameter (at least one of the above-mentioned specific parameters) included in SSB-MTC3.

[0095] For measurement results based on the SMTC corresponding to a specific PLMN ID (SMTC set for a specific PLMN ID), the wireless communication device may report only to the device (eg, parent node / base station) corresponding to the specific PLMN ID.

[0096] In addition, for measurement results based on the SMTC corresponding to a specific PLMN ID (SMTC set for a specific PLMN ID), the wireless communication device can also report to the device corresponding to the specific PLMN ID (for example, the parent node / base station) and the device corresponding to the specific PLMN ID.

[0097] The wireless communication device may also report the measurement result based on the SMTC corresponding to a specific PLMN ID, and the specific PLMN ID.

[0098] Parameters related to the PLMN ID may also be associated with the measurement results (eg, MeasResult / MeasResultNR) based on the SMTC.

[0099] For example, the measurement result based on SMTC (eg, MeasResult / MeasResultNR) may also include parameters related to the PLMN ID.

[0100] For example, the parameters related to the PLMN ID may also be associated with at least one of the specific parameters included in the measurement result based on SMTC (e.g., MeasResult / MeasResultNR). For example, at least one of the specific parameters (information elements) included in the measurement result based on SMTC (e.g., MeasResult / MeasResultNR) may also include parameters related to the PLMN ID.

[0101] According to the first embodiment described above, even when a wireless communication apparatus (for example, IAB) is shared among operators, it is possible to appropriately perform measurement settings and measurements.

[0102] <Second embodiment>

[0103] Separate (independent) random access channel (RACH) related settings for each specific ID (eg, PLMN ID) may also be supported.

[0104] The RACH-related configuration may be, for example, a RACH configuration for an IAB node.

[0105] Independent RACH-related settings for each specific ID may also be notified / configured for the wireless communication device (eg, IAB node).

[0106] The RACH-related settings may also be set through specific parameters. A specific ID (eg, PLMN ID) may also be associated with the specific parameters.

[0107] For example, the specific parameter may also be a parameter used (only) for IAB-MT.

[0108] For example, the specific parameter may also be at least one of: a parameter indicating a scaling factor of a period showing a baseline setting (e.g., prach-ConfigurationPeriodScaling-IAB), a parameter indicating a subframe / time slot offset of a random access opportunity (RO) defined in the baseline setting (prach-ConfigurationSOffset-IAB), and a parameter indicating a frame offset of the RO defined in the baseline setting (prach-ConfigurationFrameOffset-IAB).

[0109] In addition, the specific parameter may also be a parameter including at least one of the following: a parameter indicating a scaling factor of a period showing a baseline setting, a parameter indicating a subframe / slot offset of a random access opportunity (RO) defined in the baseline setting, and a parameter indicating a frame offset of the RO defined in the baseline setting. The specific parameter may also be, for example, at least one of a generic RACH setting (RACH-ConfigGeneric) and a serving cell setting (e.g., ServingCellConfigCommonSIB).

[0110] Alternatively, the specific parameter includes a specific ID (PLMN ID), and at least one of the following is associated with the specific ID: a parameter representing a scaling factor of a period showing a baseline setting, a parameter representing a subframe / time slot offset of a random access opportunity (RO) defined in the baseline setting, and a parameter representing a frame offset of the RO defined in the baseline setting.

[0111] According to the second embodiment described above, even when a wireless communication apparatus (for example, IAB) is shared among operators, it is possible to appropriately set a random access channel.

[0112] <Third Embodiment>

[0113] Separate (independent) and specific resource-related settings for each specific ID (eg, PLMN ID) may also be supported.

[0114] 《Implementation Method 3-1》

[0115] The setting related to the specific resource may be, for example, the setting of resources for the IAB node (MT).

[0116] The specific resource may be, for example, a soft resource. A soft resource may also mean a resource that can be dynamically switched and used as an IAB DU or an IAB MT.

[0117] The DCI (e.g., DCI format 2_5) that notifies / indicates the availability (availability) of the specific resource may also be set / indicated separately (independently) for each specific ID (e.g., PLMN ID).

[0118] A specific ID (DCI format associated with a specific ID) may also be set in a search space (e.g., an RRC parameter associated with the search space). The UE may also monitor DCI (e.g., DCI format 2_5) associated with a specific ID (PLMN ID) in the search space.

[0119] According to this method, when there are multiple parent nodes, a certain parent node can be set to monitor DCI (for example, DCI format 2_5) and other parent nodes can be set not to monitor DCI (for example, DCI format 2_5).

[0120] In addition, the RRC parameters that set the information included in the DCI (e.g., DCI format 2_5) that notifies / indicates the availability (availability) of a specific resource can also be associated with a specific ID (e.g., PLMN ID).

[0121] The RRC parameter may be, for example, at least one of a parameter (AvailabilityCombinationsPerCell) for setting the combinations of availability (Availability Combinations) applied to the cell of the IAB DU, and a parameter (AvailabilityIndicator) for setting the monitoring of the PDCCH for the availability indicator (Availability Indicators (AI)).

[0122] The RRC parameter may also include a specific ID (eg, PLMN ID).

[0123] In addition, a specific ID (eg, PLMN ID) may also be associated with at least one of the specific parameters included in the RRC parameters.

[0124] The specific parameter may, for example, be at least one of the following: a parameter indicating the index of the parameter for setting the availability combinations (Availability Combinations) for each cell (availabilityCombinationsPerCellIndex), a parameter indicating the ID of the IAB DU cell to which the availability combinations (Availability Combinations) are applied (iab-DU-CellIdentity), a parameter indicating the (starting) position (bits) of the AvailabilityCombinationId of the indicated IAB DU cell within the DCI payload (positionInDCI-AI), a parameter indicating the availability combinations (AvailabilityCombination), a parameter indicating the ID of the availability combinations (Availability Combinations) (availabilityCombinationId), and a parameter indicating the availability of resources (resourceAvailability).

[0125] Figure 5 This is a diagram showing an example of the setting of the availability combinations involved in Implementation 3-1. Figure 5 In the example shown, AvailabilityCombinationsPerCell includes information related to PLMNID (plmn-id).

[0126] Use as Figure 5 The information elements shown enable the IAB node to determine available resources set for each PLMN ID.

[0127] In addition, Figure 5 In the example shown, an example is shown in which a parameter indicating a PLMN ID is included in AvailabilityCombinationsPerCell, but the PLMN ID may be associated with a specific parameter (at least one of the above-mentioned specific parameters) included in AvailabilityCombinationsPerCell.

[0128] Implementation Method 3-2

[0129] The setting related to the specific resource may be, for example, the setting of resources for the IAB node (MT).

[0130] The specific resource may be, for example, a TDD configuration. The TDD configuration may be, for example, a TDD configuration for an IAB node (MT) (for example, TDD-UL-DL-ConfigDedicated-IAB-MT / TDD-UL-DL-ConfigDedicated-IAB-MT-r16).

[0131] A specific ID (PLMN ID) can also be associated with the TDD setting.

[0132] The TDD configuration may include a specific ID (PLMN ID). In addition, the specific ID (PLMN ID) may be associated with at least one of the specific parameters in the TDD configuration.

[0133] For a certain resource, when DL / UL is set for the first PLMN ID and FL (flexible) is set for the second PLMN ID, the certain resource can also be determined as a resource used (preferentially) by the first PLMN ID.

[0134] The resources in the same direction (for example, DL or UL) that are associated with different PLMN IDs may be resources shared among the multiple PLMNs (may also be referred to as common resources).

[0135] The wireless communication device (for example, IAB MT) may not assume that UL (or DL) for a different PLMN ID is set / indicated in the resources (time resources) for which DL (or UL) is set / indicated for a certain PLMN ID.

[0136] The above-mentioned shared resources are described below.

[0137] The wireless communication device (eg, IAB node) may also receive information related to the PLMN ID associated with the shared resource.

[0138] The information may also be information indicating whether a wireless communication device corresponding to a specific PLMN ID can use the shared resources. The information may also be information notifying / indicating TDD settings (time slot format) for a specific PLMN ID. The information may also be information notifying / indicating the PLMN ID associated with the shared resources.

[0139] This information may be transmitted using an existing DCI format (eg, DCI format 2_1), for example. The RNTI (Radio Network Temporary Identifier) ​​for the DCI and the search space / CORESET corresponding to the DCI may also be associated with the PLMN ID.

[0140] In addition, this information may be, for example, a new DCI format (specified in Rel. 18 or later).

[0141] The operation of the IAB node may be specified in the case where transmission / reception of a PLMN ID different from the PLMN ID associated with a common resource (at least one of the same symbol as the common resource and the same time slot as the common resource) is indicated / set in the common resource.

[0142] For example, the IAB node may not assume / expect that, in a shared resource (the same codeword as the shared resource, and at least one in the same time slot as the shared resource), the sending / receiving of a PLMN ID different from the PLMN ID associated with the shared resource is set / instructed (operation example 1).

[0143] For example, in a case where the transmission and reception of a PLMN ID different from the PLMN ID associated with the shared resource (the same codeword as the shared resource, and at least one in the same time slot as the shared resource) is set / indicated, the IAB node may ignore the setting / instruction (operation example 2).

[0144] For example, when the transmission and reception of a PLMN ID different from the PLMN ID associated with the shared resource (the same codeword as the shared resource, and at least one in the same time slot as the shared resource) is set / instructed in the shared resource, the IAB node can also change / update / determine the PLMN ID associated with the shared resource based on the setting / instruction (operation example 3).

[0145] In addition, whether to apply at least one of the examples of the operation of the IAB node may also be different based on whether the resource set / indicated is the same symbol as the shared resource or whether it is a resource in the same time slot as the shared resource. For example, when the resource set / indicated is the same symbol as the shared resource, operation example 1 (or operation example 2 / 3) may also be applied, and when the resource set / indicated is a resource in the same time slot as the shared resource, operation example 2 (or operation example 1 / 3) may also be applied.

[0168] (Wireless Communication System)

[0169] 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.

[0170] Figure 61 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.

[0171] In addition, the wireless communication system 1 can also support dual connectivity (Multi-RAT Dual Connectivity (MR-DC)) between multiple radio access technologies (Radio Access Technology (RAT)). MR-DC can also include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA))) and NR (E-UTRA-NR Dual Connectivity (E-UTRA-NR Dual Connectivity (EN-DC))), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NR-E-UTRA Dual Connectivity (NE-DC))), etc.

[0172] In EN-DC, the base station (eNB) of LTE (E-UTRA) is the master node (Master Node (MN)), and the base station (gNB) of NR is the secondary node (Secondary Node (SN)). In NE-DC, the base station (gNB) of NR is the MN, and the base station (eNB) of LTE (E-UTRA) is the SN.

[0173] The wireless communication system 1 can also support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity (NR-NR Dual Connectivity (NN-DC)) where both MN and SN are NR base stations (gNB)).

[0174] 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.

[0175] 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).

[0176] 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 (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.

[0177] 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).

[0178] 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.

[0180] The user terminal 20 may also be a terminal that supports at least one of communication modes such as LTE, LTE-A, and 5G.

[0181] 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.

[0182] 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.

[0183] 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.

[0184] In addition, as uplink channels, an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20), an uplink control channel (Physical Uplink Control Channel (PUCCH))), a random access channel (Physical Random Access Channel (PRACH)) and the like can also be used in the wireless communication system 1.

[0185] 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.

[0186] 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.

[0187] 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 rewritten as DL data, and the PUSCH may also be rewritten as UL data.

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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.

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.

[0193] 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.

[0194] 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).

[0256] (Variation Example)

[0257] In addition, the terms described in the present disclosure and the terms required for understanding the present disclosure may also be replaced with terms having the same or similar meanings. For example, channels, code elements, and signals (signals or signaling) may also be rewritten with each other. In addition, a signal may also be a message. A reference signal may also be referred to as RS, and may also be referred to as a pilot, a pilot signal, etc. depending on the standard applied. In addition, a component carrier (CC) may also be referred to as a cell, a frequency carrier, a carrier frequency, etc.

[0258] A wireless frame may also be composed of one or more periods (frames) in the time domain. Each period (frame) of the one or more periods (frames) constituting a wireless frame may also be referred to as a subframe. Further, a subframe may also be composed of one or more time slots in the time domain. A subframe may also be a fixed time length (e.g., 1 ms) that is not dependent on a parameter set (numerology).

[0259] Here, the parameter set may also be a communication parameter applied in at least one of the transmission and reception of a certain signal or channel. For example, the parameter set may also represent at least one of a subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), the number of symbols per TTI, a wireless frame structure, a specific filter processing performed by a transmitter and receiver in the frequency domain, a specific windowing processing performed by a transmitter and receiver in the time domain, and the like.

[0260] 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.

[0261] 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 a smaller number of 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] 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.

[0267] 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.

[0268] 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.

[0269] 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.

[0270] In addition, an RB may 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.

[0271] 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.

[0272] 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.

[0273] A Bandwidth Part (BWP) (also referred to as a partial bandwidth, etc.) may also represent a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, a common RB may also be identified by an index of the RB relative to a common reference point of the carrier. PRBs may also be defined in a BWP and numbered within the BWP.

[0274] 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.

[0275] At least one of the set BWPs may be activated, and the UE may not assume that a specific signal / channel is transmitted or received outside the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may also be rewritten as "BWP".

[0276] 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.

[0277] 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.

[0278] 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.

[0279] 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.

[0280] 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.

[0281] 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.

[0282] 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.

[0283] 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)).

[0284] 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).

[0285] 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).

[0286] 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.

[0287] 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.

[0291] 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.

[0292] In the present disclosure, the base station sending information to the terminal may also be rewritten as the base station instructing the terminal to control / operate based on the information.

[0293] In the present disclosure, terms such as “mobile station (MS)”, “user terminal”, “user device (User Equipment (UE))”, and “terminal” can be used interchangeably.

[0310] 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 replaced by the 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", "downlink", etc. may also be rewritten as terms corresponding to communication between terminals (for example, "sidelink"). For example, uplink channels, downlink channels, etc. may also be rewritten as sidelink channels.

[0311] 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.

[0312] 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.

[0313] 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.

[0315] 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”.

[0316] 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.

[0317] 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 (e.g., searching in a table, database or other data structure), ascertaining, etc. are considered to be "determining".

[0318] 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)".

[0319] In addition, "judgment (decision)" can also refer to situations where resolving, selecting, choosing, establishing, comparing, etc. are regarded as "judgment (decision)". That is, "judgment (decision)" can also refer to situations where some operations are regarded as "judgment (decision)".

[0320] In addition, "judge (decide)" can also be rewritten as "assuming (assuming)", "expecting (expecting)", "considering (considering)" and so on.

[0321] The “maximum transmit power” recorded in the present disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated UE maximum transmit power).

[0322] 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 can include the situation where one or more intermediate elements exist between the two elements that are "connected" or "coupled" to each other. The combination or connection between the elements can be physical, logical, or a combination thereof. For example, "connection" can also be rewritten as "access".

[0323] 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 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.

[0324] 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".
