[0026] (Resource Sharing)

[0027] In future wireless communication systems (for example, Rel. 18 and later), resource sharing is being studied for the purpose of efficiently utilizing frequency bands (existing frequency bands and new high-frequency bands).

[0028] In resource sharing, a radio access network (RAN) can be shared among multiple operators, network (NW, such as base stations) investment costs can be divided for each operator, and multiple base stations can be installed.

[0029] For example, by sharing antennas / sites (land / steel towers, etc.) among multiple operators, the site construction costs can be shared among the multiple operators.

[0030] Furthermore, by sharing a distributed node (eg, a distributed unit (DU)) / aggregation node (eg, a central unit (CU)) among a plurality of operators (eg, sharing a hardware base), it is possible to share device costs among the plurality of operators.

[0031] In addition, by sharing frequency / antenna units (eg, Radio Units (RUs)) among multiple operators, resource utilization efficiency is improved. For example, resources not used by one operator can be used by other operators.

[0032] Figure 1A to Figure 1D This is a diagram showing an example of network sharing.

[0033] Figure 1A This is an example of site sharing. Figure 1AAs shown in the figure, in site sharing, antennas / sites are shared between multiple operators. On the other hand, the service platform, HSS (Home Subscriber Server) / HLR (Home Location Register), core network (CN) packet switching (PS), base stations, and cells / frequencies are independent for each of the multiple operators.

[0034] Figure 1B This is an example of MORAN (Multi Operator RAN). Figure 1B As 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, the service platform, HSS / HLR, CN PS, other parts of the base station (e.g., the software of the base station), and cell / frequency are independent for each of the multiple operators.

[0035] Figure 1C This is an example of a MOCN (Multi Operator Core Network). Figure 1C As shown, in MOCN, multiple operators share base stations and cells / frequencies. On the other hand, the service platform, HSS / HLR, and CN PS are independent for each of the multiple operators.

[0036] Figure 1D An example of a GWCN (Gateway Core Network) is shown. Figure 1D As shown, in the GWCN, multiple operators share CN PS, base stations, and cells / frequencies. On the other hand, the service platform and HSS / HLR are independent for each of the multiple operators.

[0037] In MOCN / GWCN, it is envisaged that multiple operators share cells / frequencies.

[0038] In this case, there is a concern that interference of DL / UL signals (Cross Link Interference (CLI)) may occur between a UE corresponding to the first operator and a UE corresponding to the second operator, and between a plurality of base stations.

[0039] Figure 2 is a diagram showing an example of CLI. Figure 2The example shown shows communication between a base station (gNB#1) corresponding to operator #1 (MNO#1), a base station (gNB#2) corresponding to operator #2 (MNO#2), a UE (UE#1) corresponding to MNO#1, and UEs (UE#2 and #3) corresponding to MNO#2.

[0040] exist Figure 2 In the example shown, although gNB#1 and gNB#2 are recorded separately, these base stations can be built in the same location and share equipment, or they can be built in different locations and share frequencies.

[0041] exist Figure 2 In the example shown, it is considered that when UE#1 receives a DL signal, interference (UE-UE interference) occurs due to UL signals from UE#2 and #3.

[0042] In addition, Figure 2 In the example shown, consider interference (BS-BS interference) caused by the DL signal from gNB#1 when gNB#2 receives UL signals from UE#2 and #3.

[0043] However, in these CLIs, there is insufficient research on how to distinguish / determine which operator's gNB / UE is causing interference. In existing specifications, although the operation during CLI detection depends on the base station, there is insufficient research on the operation related to interference prevention that takes into account the impact on other operators. If this research is insufficient, flexible communication operations cannot be performed for each operator, and there is a concern that the improvement of communication quality will be suppressed.

[0044] Therefore, the inventors of the present invention have come up with a method for controlling interference when frequencies / cells are shared between operators in order to efficiently establish sites / use frequencies through resource sharing.

[0045] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The wireless communication methods involved in each embodiment can be applied individually or in combination.

[0070] The UE / base station may also determine that interference is occurring when the received power / received quality / measurement result (for example, RSRP / RSRQ / SINR) of a specific channel / reference signal is less than a specific threshold (below a specific threshold).

[0071] In the present disclosure, "it is determined that the UE / base station is interfered" can also be rewritten as "the reception power / reception quality / measurement result of a specific signal received by the UE / base station becomes less than a specific threshold (below a specific threshold)". The specific signal will be described in detail below.

[0072] <First Embodiment>

[0073] A first embodiment relates to a method of identifying / detecting interference in a common frequency.

[0074] 《Implementation Method 1-1》

[0075] The UE / base station may also detect interference based on the measurement of specific signals. The UE / base station may also determine interference based on the measurement of specific signals.

[0076] The specific signal may be, for example, at least one of a specific DL signal (eg, PDSCH / PDCCH / PBCH / CSI-RS / SSB / SS) and a specific UL signal (eg, PUSCH / PUCCH / SRS / PRACH).

[0077] The specific signal may be a newly defined interference detection signal.

[0078] The specific signal may be determined individually for each operator. It is also possible to support that the specific signal is different for each operator.

[0079] The setting for the specific signal may be set individually for each operator. It is also possible to support that the setting for the specific signal is different for each operator.

[0080] The specific signal setting may be, for example, at least one of the type of signal, the frequency / time resource of the signal, and the cycle / timing of the signal.

[0081] The configuration of this specific signal may also be performed using higher layer signaling (eg, system information / RRC signaling).

[0082] The specific signal may also be determined based on reported UE capability information (UE Capability Information). It may also be supported that the specific signal is different based on the reported UE capability information.

[0083] The specific signal may also be sent by the UE / base station causing interference (interfering UE / base station).

[0084] The specific signal may also be sent by the interfered UE / base station (interfered UE / base station).

[0085] The UE / base station providing interference may also measure the specific signal. In this case, the specific signal may also be a signal sent by a UE / base station corresponding to another operator (MNO).

[0086] The interfered UE / base station may also measure the specific signal. In this case, the specific signal may also be a signal sent by a UE / base station corresponding to another operator (MNO).

[0087] The interfering UE / base station may also send / report the measurement result of the specific signal to the interfered UE / base station. At this time, the measurement result may also be reported to the UE / base station corresponding to other operators (MNO).

[0088] The interfered UE / base station may also send / report the measurement result of the specific signal to the interfering UE / base station. At this time, the measurement result may also be reported to the UE / base station corresponding to other operators (MNO).

[0089] Figure 3 FIG. 1 is a diagram showing an example of interference measurement according to Embodiment 1-1. Figure 3 The example shown shows communication between a base station (gNB#1) corresponding to operator #1 (MNO#1), a base station (gNB#2) corresponding to operator #2 (MNO#2), a UE (UE#1) corresponding to MNO#1, and UEs (UE#2 and #3) corresponding to MNO#2.

[0090] exist Figure 3 In the example shown, although gNB#1 and gNB#2 are recorded separately, these base stations can be built in the same location and share equipment, or they can be built in different locations and share frequencies.

[0091] exist Figure 3 In the example shown, when UE#1 receives a DL signal (e.g., SSB) from gNB#1, interference caused by UL signals (e.g., CSI-RS) from UE#2 and #3 occurs. At this time, the UE can detect the interference by measuring the DL signal. Alternatively, the UE can also detect the interference by measuring the UL signal.

[0092] 《Implementation Method 1-2》

[0093] The UE / base station may also detect interference based on information related to the location of the UE / base station (including the UE / base station and at least one of other UE / base stations). The UE / base station may also determine interference based on the information related to the location.

[0094] The information related to the location may be, for example, positioning information / positioning system information. The information related to the location may be information based on GNSS (Global Navigation Satellite System) / Global Positioning System (GPS), or information related to the transmission path (pass) of the signal. The information related to the transmission path of the signal may be, for example, information related to the angle of arrival (Angle of Arrival (AoA)) / angle of departure (Angle of Departure (AoD)) of the signal.

[0095] The location information of base stations / UEs (surrounding base stations / UEs) using the common frequency can also be shared between operators.

[0096] For example, the location information may be maintained / acquired by each base station, may be notified to the UE / base station from a higher-level node, may be notified to the UE / base station from a base station of another operator, or may be notified to the UE / base station from a location management function (LMF).

[0097] The UE may also be provided with UE capability information, which is used to report support for detection / determination of interference based on location-related information. The UE may also report the UE capability information to the network.

[0098] In addition, this embodiment 1-2 can also be used in combination with at least one method described in the above embodiment 1-1.

[0099] According to the above first embodiment, even when a common frequency is used, interference can be appropriately detected / determined.

[0100] <Second Embodiment>

[0101] The second embodiment relates to operations upon detection / determination of interference in a shared frequency.

[0102] 《Implementation Method 2-0》

[0103] In the present disclosure, at least one of the following situations 1 to 3 is assumed as a situation of interference:

[0104] Scenario 1: A UE of another MNO connected to another cell (base station) is an interfering UE (see Figure 4A );

[0105] Scenario 2: The UE of another MNO connected to the same cell (base station) is the UE that provides interference (refer to Figure 4B );

[0106] Scenario 3: The base station of another MNO is the base station for interference (refer to Figure 4C ).

[0107] For the above scenarios 1 to 3, the operations of the UE / base station when detecting / determining interference may be separately specified. For the above scenarios 1 to 3, the operations of the UE / base station when detecting / determining interference may be different.

[0108] The following describes the specific operations of UE / base station when detecting / determining interference. At least one of the operations when detecting / determining interference shown below can also be applied to at least one of the above-mentioned situations 1-3.

[0109] 《Implementation Method 2-1》

[0110] The UE / base station may also report that interference has been detected.

[0111] The UE may also report that interference has been detected to at least one of the base station of the MNO, the base station of another MNO, and the UE of another MNO.

[0112] At least one of information related to interference detection (for example, information indicating that interference detection has been performed) and information related to UE / base station causing interference may be notified between base stations of different MNOs.

[0113] The UE may also be notified by the base stations of other MNOs that the UE is an interfering UE.

[0114] Figure 5 FIG. 2 is a diagram showing an example of interference measurement according to Embodiment 2-1. Figure 5 The example shown shows communication between a base station (gNB#1) corresponding to operator #1 (MNO#1), a base station (gNB#2) corresponding to operator #2 (MNO#2), a UE (UE#1) corresponding to MNO#1, and UEs (UE#2 and #3) corresponding to MNO#2.

[0115] exist Figure 5 In the example shown, although gNB#1 and gNB#2 are recorded separately, these base stations can be built in the same location and share equipment, or they can be built in different locations and share frequencies.

[0116] exist Figure 5 In the example shown, when UE#1 receives a DL signal from gNB#1, interference occurs due to UL signals from UE#2 and #3. At this time, the UE can detect the interference by measuring the UL / DL signals.

[0117] exist Figure 5 In the example shown, the UE sends information indicating that interference detection has been performed to at least one of gNB#1, gNB#2, and UE#2 / UE#3.

[0118] 《Implementation Method 2-2》

[0119] The UE / base station providing interference may also be notified of an indication of an operation related to interference. The indication may be, for example, an indication of an operation for suppressing interference. In addition, the indication may also be information related to the detection of the above-mentioned interference.

[0120] This information is transmitted to base stations (cells) / UEs around the UE using common control information. The common control information may be, for example, group common uplink control information (UCI).

[0121] In addition, the UE may also receive the information from base stations / UEs of other MNOs.

[0122] Resources for sending / receiving the information may also be set for the UE. The resources may be UE-specific (MNO-specific) resources or resources common to multiple MNOs.

[0123] The operation related to interference may also be at least one of an operation related to transmission power and an operation related to specific resources.

[0124] For example, the interfering UE may also assume / expect to be scheduled / triggered for UL transmission with limited (eg, reduced) transmission power. The base station may also schedule / trigger UL transmission with limited (eg, reduced) transmission power for the interfering UE.

[0125] For example, the limited (reduced) transmission power may be derived by multiplying a derived formula of the transmission power of the existing UL transmission (e.g., PUCCH / PUSCH / SRS) by a specific constant (the constant is a positive number less than 1). In addition, the limited (reduced) transmission power may be derived by subtracting a specific value from a derived formula of the transmission power of the existing UL transmission (e.g., PUCCH / PUSCH / SRS). Information related to the specific constant / value may also be notified to the UE using high-layer signaling (RRC / MACCE) / physical layer signaling (DCI).

[0126] In addition, for example, the limitation (reduction) of the transmission power may also be applied in multiple stages. For example, when the transmission power of the UE to be interfered meets the conditions for interference after the initial indication of the limitation of the transmission power, the base station may also indicate to the UE to be interfered that further limitation is applied to the transmission power after the limitation.

[0127] In addition, for example, the UE for interference may also assume / expect to be scheduled / triggered for UL transmission and the time / frequency / space resources of the UL transmission may be limited. The base station may also schedule / trigger UL transmission for the UE for interference with time / frequency / space resources limited compared to the resources of UL transmission that can be scheduled / triggered for the UE not for interference.

[0128] For example, the base station may also determine that, during a specific period after interference detection, a specific time resource is a resource for a UE / base station of a specific MNO. At this time, control may also be performed so that the UE providing interference does not schedule / trigger UL transmission using at least a portion of the time resources including the specific time resource.

[0129] For example, the base station may also determine that the specific frequency resources are resources for the UE / base station of the specific MNO during a specific period after the interference detection. At this time, control may also be performed so that the UE providing interference does not schedule / trigger UL transmission using at least a portion of the frequency resources including the specific frequency resources.

[0130] For example, the base station may determine not to instruct the interfering UE to use a specific spatial resource (eg, beam) during a specific period after interference detection. In this case, the interfering UE may also be restricted from using the specific spatial resource (beam).

[0131] These specific periods may be pre-specified in the specification, may be set to the UE via higher layer signaling, or may be determined based on reports of UE capability information.

[0132] 《Implementation Method 2-3》

[0133] The UE / base station notified of the indication of the interference-related operation may also send feedback information for the indication. The feedback information may also be information indicating, for example, that the interference-related operation is applied.

[0134] The feedback information may be transmitted using a specific UL / DL signal, for example.

[0135] The UE may also report the feedback information (eg, information indicating that an operation related to interference is applied) to at least one of the base station of the own MNO, the base station of another MNO, and the UE of another MNO.

[0136] Furthermore, information related to the operation related to interference (for example, information indicating that the operation related to interference is applied) may be notified between base stations of different MNOs.

[0137] In addition, the UE may also be notified by the base stations of other MNOs that at least one of the base stations of the own MNO, the base stations of other MNOs, and the UEs of other MNOs has applied an operation related to interference.

[0138] Figure 6 FIG. 2 is a diagram showing an example of interference measurement according to Embodiment 2-3. Figure 6The example shown shows communication between a base station (gNB#1) corresponding to operator #1 (MNO#1), a base station (gNB#2) corresponding to operator #2 (MNO#2), a UE (UE#1) corresponding to MNO#1, and UEs (UE#2 and #3) corresponding to MNO#2.

[0139] exist Figure 6 In the example shown, although gNB#1 and gNB#2 are recorded separately, these base stations can be built in the same location and share equipment, or they can be built in different locations and share frequencies.

[0140] exist Figure 6 In the example shown, UE#1 receives an indication of an interference-related operation. The UE performs the interference-related operation based on the indication, and sends feedback information indicating that the operation has been applied to at least one of gNB#1, gNB#2, and UE#2 / UE#3.

[0141] According to the above second embodiment, interference in the shared frequency can be appropriately suppressed / reduced.

[0142] <Supplement>

[0143] At least one of the above-mentioned implementation modes may also be applied only to a UE that reports a specific UE capability (UE capability) or supports the specific UE capability.

[0144] The specific UE capability may also indicate support for specific processing / operation / control / information for at least one of the above-mentioned embodiments (for example, measurement of interference based on specific signals, measurement of interference based on location information, reporting / notification of interference detection, operations related to interference, feedback on indications for operations related to interference, at least one of the above).

[0145] In addition, the above-mentioned specific UE capabilities may also be capabilities that are applied across the entire frequency (commonly regardless of the frequency), capabilities for each frequency (for example, cell, band, BWP), capabilities for each frequency range (for example, Frequency Range 1 (FR1)), FR2, FR3, FR4, FR5, FR2-1, FR2-2), or capabilities for each subcarrier spacing (Sub Carrier Spacing (SCS)).

[0146] Furthermore, the specific UE capability may be a capability applied across full-duplex modes (commonly regardless of the duplex mode) or a capability applied by duplex mode (eg, time division duplex (TDD) or frequency division duplex (FDD)).

[0147] In addition, at least one of the above embodiments may also be applied when the UE is configured with specific information associated with the above embodiments through high-layer signaling. For example, the specific information may also be any RRC parameter for a specific version (eg, Rel. 18).

[0148] The UE may also apply operations such as Rel. 15 / 16 without supporting at least one of the above-mentioned specific UE capabilities or without being set with the above-mentioned specific information.

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.

[0161] Figure 7 1 is a diagram showing an example of a schematic structure of a wireless communication system according to an embodiment. The wireless communication system 1 (may also be simply referred to as the 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 (5GNR), or the like.

[0162] In addition, the wireless communication system 1 may also support dual connectivity (Multi-RAT Dual Connectivity (MR-DC)) between multiple radio access technologies (Radio Access Technology (RAT)). MR-DC may 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.

[0163] 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.

[0164] The wireless communication system 1 may 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)).

[0165] 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.

[0166] 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).

[0167] 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.

[0168] Furthermore, the user terminal 20 may perform communication using at least one of time division duplex (TDD) and frequency division duplex (FDD) in each CC.

[0169] Multiple base stations 10 may also be connected by wire (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.

[0170] The base station 10 may be connected to the core network 30 via other base stations 10 or directly. The core network 30 may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0171] The core network 30 may also include, for example, network functions (NF) such as User Plane Function (UPF), Access and Mobility Management Function (AMF), Session Management Function (SMF), Unified Data Management (UDM), Application Function (AF), Data Network (DN), Location Management Function (LMF), Operation, Administration and Maintenance (Management) (OAM), etc. In addition, multiple functions may be provided by one network node. In addition, communication with an external network (e.g., the Internet) may also be performed via the DN.

[0172] The user terminal 20 may also be a terminal that supports at least one of communication modes such as LTE, LTE-A, and 5G.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] 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)), etc. can also be used in the wireless communication system 1.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] In the present disclosure, downlink, uplink, etc. may be expressed without “link.” In addition, various channels may be expressed without “Physical” at the beginning.

[0184] 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.

[0185] 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 (SS Block (SSB)), etc. In addition, SS, SSB, etc. may also be referred to as reference signals.

[0186] 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. may also be transmitted. In addition, DMRS may also be called a user terminal specific reference signal (UE-specific Reference Signal).

[0247] 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.

[0248] A time slot may also contain 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.

[0249] 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.

[0250] 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 (for example, 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.

[0251] 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.

[0252] TTI can also be a transmission time unit for a data packet (transport block), code block, code word, etc. that has been channel-coded, and can also be a processing unit for scheduling, link adaptation, etc. In addition, when TTI is given, the time interval (for example, the number of symbols) to which a transport block, code block, code word, etc. is actually mapped can also be shorter than the TTI.

[0253] In addition, when a time slot or a mini time slot is called a TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) may 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 may also be controlled.

[0254] 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.

[0255] In addition, a long TTI (eg, normal TTI, subframe, etc.) may be rewritten as a TTI having a time length exceeding 1 ms, and a short TTI (eg, shortened TTI, etc.) may be rewritten as a TTI having a TTI length shorter than that of a long TTI and longer than 1 ms.

[0256] Resource Block (RB) is a resource allocation unit in the time domain and frequency domain, and may also 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, it may be 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0257] 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.

[0258] 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.

[0259] 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.

[0260] Bandwidth Part (BWP) (also referred to as partial bandwidth, etc.) can also represent a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, common RBs can also be identified by the index of the RB based on the common reference point of the carrier. PRBs can also be defined in a BWP and numbered within the BWP.

[0261] 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.

[0262] 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".

[0263] 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 per 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.

[0264] 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.

[0265] 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. The 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.

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.

[0267] In addition, 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.

[0268] 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 added. The output information, signals, etc. may also be deleted. The input information, signals, etc. may also be sent to other devices.

[0269] 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.

[0270] 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)).

[0271] 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).

[0272] The determination may be made using a value represented by one bit (0 or 1), a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(eg, comparison with a specific value).

[0273] 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 module, application, software application, software package, routine, sub-routine, object, executable files, execution thread, procedure, function, etc.

[0274] In addition, software, instructions, information, etc. may also be sent and received via a transmission medium. For example, when the 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.

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.

[0279] 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.

[0280] In the present disclosure, terms such as “mobile station (MS)”, “user terminal”, “user device (User Equipment (UE))”, and “terminal” can be used interchangeably.

[0297] 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.

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.

[0304] The term "determining" used in this disclosure may include a variety of actions. 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".

[0305] In addition, “judgment (decision)” may also refer to situations where receiving (e.g., receiving information), transmitting (e.g., sending information), input (input), output (output), accessing (e.g., accessing data in a memory), etc. are regarded as making a “judgment (decision)”.

The combination or connection between elements may be physical, logical, or a combination thereof. For example, "connection" may also be rewritten as "access".

[0310] 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.

[0311] 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".

[0312] 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.

[0313] 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.

[0314] In the present disclosure, "below", "less than", "above", "more than", "equal to", etc. can also be rephrased with each other. In addition, in the present disclosure, sentences meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. can also be rephrased with each other, without being limited to the original degree, comparative degree, and superlative degree. In addition, in the present disclosure, sentences meaning "good", "bad", "big", "small", "high", "low", "early", "late", "wide", "narrow", etc. can also be rephrased with each other as expressions with "ith" attached, without being limited to the original degree, comparative degree, and superlative degree (for example, "highest" can also be rephrased with "i-th highest").

[0315] In the present disclosure, “of,” “for,” “regarding,” “related to,” “associated with,” etc. may also be replaced by each other.

[0316] The invention involved in the present disclosure is 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.
