Description

Technical Field

[0001] The present disclosure relates to a terminal and a wireless communication method supporting measurement of inter-link interference (CLI). Background Art

[0002] The 3rd Generation Partnership Project (3GPP, registered trademark) has standardized the 5th generation mobile communication system (also called 5G, New Radio (NR) or Next Generation (NG)), and has also standardized the next generation called Beyond 5G, 5G Evolution or 6G.

[0003] For example, in 3GPP version 18, the extension of the duplex method is studied (Non-Patent Document 1). Specifically, XDD (Cross Division Duplex) is proposed. XDD (Cross Division Duplex) is a new duplex method that can use the downlink (DL) and uplink (UL) simultaneously within a carrier in the time division duplex (TDD) band.

[0004] In the expansion of such duplexing methods, technologies for interference countermeasures such as Cross Link Interference (CLI) have become important. The measurement of CLI by a terminal (User Equipment, UE) is specified in 3GPP Release 16 and the like (Non-Patent Document 2).

[0009] The above-mentioned CLI measurement is performed in a higher layer, specifically, in layer 3. Therefore, a plurality of CLI values ​​within a certain period are equalized by layer 3 filtering and used as CLI, and therefore does not necessarily indicate the latest CLI.

[0010] On the other hand, when considering the expansion of duplexing methods such as XDD, resource scheduling based on an extremely short cycle may be required, and the instantaneous CLI value is also considered to be useful.

[0011] Therefore, the following disclosure has been made in view of such a situation, and an object thereof is to provide a terminal and a wireless communication method capable of performing measurement of inter-link interference (CLI) suitable for extended duplexing methods such as XDD.

[0012] One embodiment of the present disclosure is a terminal (UE 200) comprising: a control unit (control unit 270) that controls the measurement of inter-link interference in a low layer; and a sending unit (control signal / reference signal processing unit 240) that periodically, semi-continuously or non-periodically sends a report of the measured inter-link interference to a network.

[0013] One embodiment of the present disclosure is a wireless communication method, which includes the following steps: a terminal controls the measurement of inter-link interference in a low layer; and the terminal periodically, semi-continuously or aperiodically sends a report of the measured inter-link interference to a network.

[0024] Hereinafter, the embodiments will be described based on the drawings. In addition, the same or similar reference numerals are given to the same functions and structures, and the description thereof will be appropriately omitted.

[0025] (1) Overall schematic structure of wireless communication system

[0026] Figure 1 This is a schematic diagram of the overall structure of the wireless communication system 10 of this embodiment. The wireless communication system 10 is a wireless communication system that complies with the 5G New Radio (NR: New Radio), and includes a next-generation radio access network (Next Generation-Radio Access Network) 20 (hereinafter referred to as NG-RAN 20) and a terminal 200 (hereinafter referred to as UE 200, User Equipment (user device), UE). In addition, the wireless communication system 10 may also be a wireless communication system that complies with a method called Beyond 5G, 5GEvolution or 6G.

[0027] NG-RAN 20 includes a radio base station 100 (hereinafter referred to as gNB 100). In addition, the specific structure of the wireless communication system 10 including the number of gNBs and UEs is not limited to Figure 1 Example shown.

[0028] NG-RAN 20 actually includes multiple NG-RAN nodes, specifically, multiple gNBs (or ng-eNBs), which are connected to a 5G-compliant core network (5GC, not shown). In addition, NG-RAN 20 and 5GC can be simply referred to as "network".

[0029] The gNB 100 is a 5G-compliant wireless base station, and performs 5G-compliant wireless communications with the UE 200. The gNB 100 and the UE 200 can support Massive MIMO (Multiple Input Multiple Output) that generates an antenna beam with higher directivity (hereinafter referred to as beam BM) by controlling wireless signals transmitted from multiple antenna elements, Carrier Aggregation (CA) that bundles and uses multiple component carriers (CCs), and Dual Connectivity (DC) that simultaneously communicates between the UE and two NG-RAN nodes.

[0030] In addition, the type of DC can be multi-radio access technology dual connectivity (MR-DC: Multi-RAT Dual Connectivity) using multiple radio access technologies, or it can be NR-NR dual connectivity (NR-DC: NR-NR Dual Connectivity) using only NR.

[0031] In addition, MR-DC can be E-UTRA-NR dual connectivity (EN-DC: E-UTRA-NR Dual Connectivity) in which eNB constitutes the master node (MN) and gNB constitutes the slave node (SN), or the opposite NR-E-UTRA dual connectivity (NE-DC: NR-E-UTRA Dual Connectivity).

[0032] gNB 100 can perform spatial and time division transmission of multiple beam BMs with different transmission directions (also referred to as directions, radiation directions or coverage ranges, etc.). In addition, gNB 100 can transmit multiple beam BMs simultaneously.

[0033] In addition, the wireless communication system 10 may support a plurality of frequency ranges (FR). Specifically, the following frequency ranges may be supported.

[0034] FR1: 410MHz~7.125GHz

[0035] FR2-1: 24.25 GHz to 52.6 GHz

[0036] In FR1, a sub-carrier spacing (SCS) of 15, 30 or 60 kHz and a bandwidth (BW) of 5 to 100 MHz can be used. The frequency of FR2-1 is higher than that of FR1, and a sub-carrier spacing (SCS) of 60 or 120 kHz (including 240 kHz) and a bandwidth (BW) of 50 to 400 MHz can be used.

[0037] In addition, SCS can also be interpreted as a numerology. The numerology is defined in 3GPP TS38.300 and corresponds to a subcarrier spacing in the frequency domain.

[0038] Furthermore, the wireless communication system 10 also supports a frequency band higher than the frequency band of FR2-1. Specifically, the wireless communication system 10 supports a frequency band exceeding 52.6 GHz and up to 71 GHz. Such a high frequency band may also be referred to as FR2-2.

[0039] When using a frequency band exceeding 52.6 GHz, CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Multiplexing) / DFT-S-OFDM (Discrete Fourier Transform-Spread OFDM) with a larger sub-carrier spacing (SCS) can be applied.

[0040] Furthermore, in high frequency bands such as FR2-2, as described above, the increase in phase noise between carriers becomes a problem, and therefore, it may be necessary to apply a larger (wider) SCS or a single carrier waveform.

[0041] The larger the SCS is, the shorter the symbol / CP (Cyclic Prefix) period and the slot period are (when the structure of 14 symbols / slot is maintained). Figure 2 A configuration example of a radio frame, a subframe, and a time slot used in the wireless communication system 10 is shown.

[0042] When maintaining a structure of 14 symbols / time slots, the larger (wider) the SCS is, the shorter the symbol period (and time slot period) is. In addition, the symbol period can also be called the symbol length, time direction, or time domain. In addition, the frequency direction can also be called the frequency domain, resource block, subcarrier, BWP (Bandwidth part), etc.

[0043] Frequency resources may include component carriers, subcarriers, resource blocks (RBs), resource block groups (RBGs), BWPs (Bandwidth part), etc. Time resources may include symbols, slots, mini-slots, subframes, radio frames, DRX (Discontinuous Reception) cycles, etc.

[0044] In addition, the number of symbols constituting one slot does not necessarily have to be 14 symbols (for example, 28 or 56 symbols). In addition, the number of slots per subframe may differ depending on the SCS.

[0045] In the wireless communication system 10 , an SSB (SS / PBCH Block) composed of a synchronization signal (SS: Synchronization Signal) and a downlink physical broadcast channel (PBCH: Physical Broadcast CHannel) can be used.

[0046] SSB is periodically sent from the network mainly for UE 200 to perform cell ID and reception timing detection at the start of communication. In NR, SSB is also used for reception quality measurement of each cell. As the transmission period (periodicity) of SSB, 5, 10, 20, 40, 80, 160 milliseconds, etc. can be specified. In addition, a transmission period of 20 milliseconds can also be assumed for UE 200 that initially accesses.

[0047] In addition, multiple duplex modes (Duplex) can be used in the wireless communication system 10. Specifically, time division duplex (TDD) and frequency division duplex (FDD) can be used. The duplex mode can be interpreted as a mode of achieving simultaneous transmission and reception (duplex communication) of downlink (DL) and uplink (UL).

[0048] Furthermore, in the wireless communication system 10 , other duplexing schemes capable of using DL and UL simultaneously may be used. Specifically, XDD (Cross Division Duplex) may be used.

[0049] Figure 3 An example of the structure of XDD is shown. Figure 3 As shown, XDD can use DL and UL simultaneously within a carrier (CC) in the TDD band. When the central part of the frequency resources within the UL carrier is used, potential cross link interference (CLI) with adjacent carriers can be avoided or mitigated. XDD can also be called a type of full duplex, or FDD full duplex, etc.

[0050] (2) Functional block structure of wireless communication system

[0051] Next, a functional block configuration of the wireless communication system 10 will be described. Specifically, a functional block configuration of the UE 200 will be described. Figure 4 This is a functional block diagram of gNB 100 and UE 200.

[0052] like Figure 4 As shown, UE 200 includes a radio signal transceiver 210 , an amplifier 220 , a modulation and demodulation unit 230 , a control signal and reference signal processing unit 240 , an encoding and decoding unit 250 , a data transceiver 260 , and a control unit 270 .

[0053] In addition, Figure 4 In the figure, only the main functional blocks related to the description of the implementation method are shown, and it should be noted that UE 200 (gNB 100) has other functional blocks (for example, a power supply unit, etc.). Figure 4 The functional block structure of UE 200 is shown. For the hardware structure, please refer to Fig. 9 .

[0054] The wireless signal transceiver 210 transmits and receives wireless signals in accordance with NR. The wireless signal transceiver 210 can support Massive MIMO (Massive MIMO) that generates a beam with higher directivity by controlling wireless (RF) signals sent from multiple antenna elements, Carrier Aggregation (CA) that bundles and uses multiple Component Carriers (CCs), and Dual Connectivity (DC) that simultaneously communicates between UE and two NG-RAN nodes.

[0055] The amplifier 220 is composed of a power amplifier (PA) / a low noise amplifier (LNA) etc. The amplifier 220 amplifies the signal output from the modulation and demodulation unit 230 to a predetermined power level. In addition, the amplifier 220 amplifies the RF signal output from the wireless signal transmission and reception unit 210 .

[0056] The modem unit 230 performs data modulation / demodulation, transmission power setting, resource block allocation, etc. for each predetermined communication target (gNB 100, etc.). In the modem unit 230, cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) / discrete Fourier transform-spread orthogonal frequency division multiplexing (DFT-S-OFDM) can also be applied. In addition, DFT-S-OFDM can be used not only for uplink (UL) but also for downlink (DL).

[0057] The control signal / reference signal processing unit 240 performs processing related to various control signals transmitted and received by the UE 200 and processing related to various reference signals transmitted and received by the UE 200 .

[0058] Specifically, the control signal / reference signal processing unit 240 receives various control signals sent from the gNB 100 via a predetermined control channel, such as a control signal of the radio resource control layer (RRC). In addition, the control signal / reference signal processing unit 240 sends various control signals to the gNB 100 via a predetermined control channel.

[0059] The control signal / reference signal processing unit 240 performs processing using reference signals (RS) such as a demodulation reference signal (DMRS: Demodulation Reference Signal) and a phase tracking reference signal (PTRS: Phase Tracking Reference Signal).

[0060] DMRS is a terminal-specific reference signal (pilot signal) known between a base station and a terminal for estimating a fading channel used for data demodulation. PTRS is a terminal-specific reference signal for estimating phase noise, which is a problem in high frequency bands.

[0061] In addition, the reference signal may include a channel state information reference signal (CSI-RS: Channel State Information-Reference Signal), a sounding reference signal (SRS: Sounding Reference Signal), and a positioning reference signal for position information (PRS: Positioning Reference Signal) in addition to the DMRS and PTRS.

[0062] In addition, the channel includes control channels and data channels. The control channel may include PDCCH, PUCCH (Physical Uplink Control Channel), RACH (Random Access Channel, Downlink Control Information (DCI) including Random Access Radio Network Temporary Identifier (RA-RNTI)), and Physical Broadcast Channel (PBCH).

[0063] In addition, the data channel includes PDSCH and PUSCH (Physical Uplink Shared Channel) etc. The data may refer to data transmitted via the data channel.

[0064] The control signal and reference signal processing unit 240 can send capability information of the UE 200 to the network. In this embodiment, the control signal and reference signal processing unit 240 can send UE capability information (UE Capability Information) related to inter-link interference (CLI) to the gNB 100.

[0065] The control signal and reference signal processing unit 240 can measure the inter-link interference and transmit a report of the measured inter-link interference to the network. In this embodiment, the control signal and reference signal processing unit 240 constitutes a transmitting unit.

[0066] The control signal / reference signal processing unit 240 may send a report of inter-link interference to the network periodically, semi-persistently, or aperiodically.

[0067] Inter-link interference (CLI) can be measured using a reference signal (RS) received by UE 200. The RS used for measuring CLI is not particularly limited, and for example, CSI-RS or the like can be used.

[0068] The control signal / reference signal processing unit 240 may send a report for each resource used for inter-link interference measurement. The resource used for inter-link interference measurement may be interpreted as a resource of an RS used for CLI measurement, and in a narrow sense may also be interpreted as a carrier or a beam.

[0069] The encoding / decoding unit 250 performs data segmentation / concatenation and channel coding / decoding, etc. for each predetermined communication target (gNB 100 or other gNB).

[0070] Specifically, the encoding / decoding unit 250 divides the data output from the data transceiver unit 260 into predetermined sizes and performs channel coding on the divided data. In addition, the encoding / decoding unit 250 decodes the data output from the modulation / demodulation unit 230 and concatenates the decoded data.

[0071] The data transceiver 260 performs transmission and reception of protocol data units (PDUs) and service data units (SDUs). Specifically, the data transceiver 260 performs assembly / disassembly of PDUs / SDUs in multiple layers (such as the medium access control layer (MAC), the radio link control layer (RLC), and the packet data convergence protocol layer (PDCP)). In addition, the data transceiver 260 performs error correction and retransmission control of data based on the hybrid automatic repeat request (HARQ).

[0072] The control unit 270 controls each functional block constituting the UE 200. In particular, in the present embodiment, the control unit 270 can control the measurement of inter-link interference. Specifically, the control unit 270 can measure the inter-link interference in a lower layer (e.g., layer 1). The lower layer is not limited to layer 1, and may include, for example, a MAC layer. Layer 1 may also be replaced by a physical layer.

[0073] In this way, the control unit 270 can control the measurement of the inter-link interference in the lower layer. In addition, the control unit 270 can also control the measurement of the inter-link interference in the higher layer, such as layer 3. In the measurement in layer 3, the values ​​of multiple CLIs within a certain period can be equalized by layer 3 filtering. Therefore, it can be interpreted that the CLI measurement in the lower layer (layer 1) represents a short-term value, and the CLI measurement in the higher layer (layer 3) represents a long-term value.

[0074] The control unit 270 may include at least one of the strength of the reference signal (eg, CLI-RSSI) and the reception quality (eg, SRS-RSRP) in the CLI report transmitted via the uplink control channel (PUCCH) or the uplink data channel (PUSCH).

[0075] The control unit 270 may set resources corresponding to the measurement items of the inter-link interference. For example, the control unit 270 may set resources for CLI reporting based on signaling based on a higher layer (e.g., RRC), downlink control information (DCI), or notification of a MAC CE (Control Element). The resources may be different or the same depending on the measurement items (e.g., RSSI, RSRP, etc.).

[0076] The control unit 270 can control the measurement of inter-link interference based on the setting of inter-link interference for each antenna beam (beam BM). Specifically, the beam BM can be set for each CLI measurement resource (set) in layer 1, or it can be represented by the activation DCI / MAC CE of the CLI measurement resource (set) in layer 1. Alternatively, the beam BM can be set for each CLI report (report) in layer 1, or it can be represented by the activation DCI / MAC CE of the CLI report (report) in layer 1.

[0077] The gNB 100 (control signal / reference signal processing unit 240) can perform settings related to the reference signal for CLI measurement, CLI measurement, and reporting in layer 1 of the above-mentioned UE 200. In addition, the gNB 100 (control signal / reference signal processing unit 240) can obtain the content of the CLI reported by the UE 200, perform scheduling of the UE 200, etc.

[0078] (3) Operation of wireless communication system

[0079] Next, the operation of the radio communication system 10 will be described. Specifically, the operation related to the CLI measurement in layer 1 of the UE 200 will be described.

[0080] (3.1) Prerequisites and Issues

[0081] The measurement and reporting of Inter-Link Interference (CLI) in Layer 3 (Layer 3 filtering) is supported by 3GPP Release 16. In the wireless communication system 10, the measurement and reporting of Inter-Link Interference (CLI) in Layer 1 may also be supported.

[0082] Inter-link interference (also called cross-link interference) processing and remote interference management (RIM) are extended functions added in 3GPP Release 16 to handle interference scenarios of TDD systems.

[0083] Figure 5 An example of CLI is shown. CLI can be deployed mainly for small cells using dynamic TDD and is a new measurement value for detecting cross-link interference between DL and UL. DL transmission in one cell interferes with UL reception in an adjacent cell (or vice versa). Based on measurements from both the terminal (device) and the wireless base station (adjacent cell), the wireless base station (scheduler) can improve the scheduling strategy and reduce the impact of cross-link interference.

[0084] Layer 3 filtering is based on a function (correlation) between the latest measured CLI value and the past historical CLI values, so the layer 3 CLI represents the long-term CLI. The long-term layer 3 CLI sometimes does not represent the latest interference level. Therefore, it is sometimes not suitable for short-term or instantaneous scheduling decisions. Therefore, the measurement and reporting of the layer 1 CLI including the latest instantaneous interference level helps in dynamic scheduling decisions.

[0085] The following describes an example of an operation that supports a layer 1 CLI report including the following items.

[0086] Behavior in the time domain of layer 1 CLI reports

[0087] Number of reports

[0088] Report content

[0089] Layer 1 CLI measurement and reporting resources

[0090] Beam propria 1CLI measurement and reporting

[0091] Figure 6 An example of beam-level CLI is shown. Figure 6 In the example shown, UE#1's UL is the interferer (aggressor) and UE#2's DL is the interfered (victim). If UE#2 can measure RSSI from two different beams, it can report the following: if DL reception is on beam #1, there is strong interference, and if DL reception is on beam #2, there is allowable interference.

[0092] Figure 7 FIG. 8 shows an example of a communication sequence related to CLI measurement and reporting. Figure 7 As shown, the UE receives a reference signal (RS) sent from the network (gNB) (step 1) and measures the CLI in layer 1 (step 2).

[0093] The UE sends the measurement results of the CLI (RSSI, RSRP, etc.) to the network as a CLI report (CLI Report) (step 3).

[0094] (3.2) Operation Overview

[0095] The operation examples described below may include the following operation examples.

[0096] (Action Example 1): Behavior in the time domain

[0097] Layer 1 CLI reporting can be periodic, semi-persistent and / or aperiodic. The reporting period to be applied can be indicated by a parameter of the CLI report configuration (eg, the Time Domain Behavior specified in 3GPP TS 38.331 (hereinafter the same)).

[0098] (Action Example 2): Report quantity

[0099] The layer 1 CLI report related to PUCCH / PUSCH can include layer 1 CLI-RSSI and layer 1 SRS-RSRP.

[0100] (Action Example 3): Report content

[0101] The maximum number of measurements / resources reported by the layer 1 CLI report may be limited (eg, a maximum number N).

[0102] (Option 1): The UE may report measurement results per measurement resource (and per beam).

[0103] (Option 2): The UE may report maximum / minimum / average measurement results.

[0104] (Action Example 4): CLI measurement resource (set) for layer 1 CLI report

[0105] For each Layer 1 CLI report, the associated measurement resource (or resource set) may be set by RRC, or indicated by activating DCI / MAC CE, or may be implicitly determined as all “possible Layer 1 CLI-RSSI and / or Layer 1 SRS-RSRP measurement resources (or resource sets)”.

[0106] In the case of layer 1 CLI-RSSI measurement and reporting, the “possible layer 1 CLI-RSSI resource (or resource set)” may be an existing CLI-RSSI measurement resource (in the case of layer 3 measurement), a ZP (Zero Power)-CSI-RS resource (set), or a newly set layer 1 CLI-RSSI measurement resource (or resource set).

[0107] In the case of layer 1 SRS-RSRP measurement and reporting, the “usable layer 1 SRS-RSRP resources (or resource sets)” may be existing SRS-RSRP measurement resources (for layer 3 measurement) or newly configured layer 1 SRS-RSRP measurement resources (or resource sets).

[0108] · The activation / triggering of layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) may be any of the following.

[0109] (Alt 1): When periodic (regular) Layer 1 CLI reporting is configured, when semi-continuous Layer 1 CLI reporting is activated, or when aperiodic Layer 1 CLI reporting is triggered, the associated Layer 1 CLI-RSSI and / or Layer 1 SRS-RSRP measurement resources (or resource sets) are activated / triggered.

[0110] (Alt 2): Detach activation from CLI report settings / activation.

[0111] (Action Example 5): Beam Stratum 1 CLI measurement and reporting

[0112] (Option 1): The beam (e.g., TCI (Transmission Configuration Indication) state, QCL (Quasi Co-Location) type of DRS (Discovery Reference Signal) or spatial relationship) can be set per layer 1 CLI measurement resource (set), or can be represented by the activation DCI / MAC CE of the layer 1 CLI measurement resource (set).

[0113] In addition, QCL / TCI states / beams can be interchangeable.

[0114] (Option 2): Beams (e.g., TCI status, QCL type of DRS, or spatial relationship) may be set per layer 1 CLI report, or may be indicated by an activation DCI / MAC CE of a layer 1 CLI report.

[0115] (3.3) Action Example 1

[0116] Layer 1 CLI reporting may be periodic, semi-continuous and / or aperiodic, and can be indicated by the parameters of the CLI report settings (eg, TimeDomainBehavior). The following options can be set.

[0117] (Option 1): Periodic Layer 1 CLI reporting

[0118] Periodic reporting of Layer 1 CLI may be reported via PUCCH or PUSCH or both.

[0119] In case of periodic layer 1 CLI reported over PUCCH, the following actions may be applied.

[0120] The reporting periodicity and offset are set for each periodic layer 1 CLI report of the PUCCH.

[0121] The PUCCH format that can be used in the periodic CLI report may be defined by the specification or may be configured by RRC. For example, the PUCCH format (PF) that can be used for PUCCH in the periodic layer 1 CLI report may be only 2, 3, 4.

[0122] PF1, 3, and 4 are called long formats, and the number of symbols is 4 to 14. PF0 and 2 are called short formats, and the number of symbols is 1 or 2. The number of information bits of PF0 and 1 is 2 bits or less (≥2), and the number of information bits of PF2 to 4 is greater than 2 bits (>2).

[0123] • The associated PUCCH resources, corresponding PUCCH reporting cells and / or BWP may be configured for each periodic layer 1 CLI report related to PUCCH.

[0124] In case of periodic layer 1 CLI reported over PUSCH, the following actions may be applied.

[0125] The allocation of time and frequency domains of PUSCH and other transmission parameters may be set for periodic CLI reporting related to PUSCH. The periodicity and offset of reporting may be set per periodic layer 1 CLI reporting. Any parameter within ConfiguredGrantConfigtype and / or configuredGrantTimer (i.e., type 1 CG PUSCH structure) may be configured.

[0126] For example, it may include periodicity and offset, time domain allocation (e.g., PUSCH start codeword and length), frequency domain allocation (e.g., the start of PRB (Physical Resource Block), the number of PRBs, activation / inactivation of frequency hopping, and frequency hopping parameters), MCS (Modulation and Coding Scheme), power control parameters, precoding information, antenna ports, spatial relationship information, path loss reference signal (RS), number of repetitions, PUSCH repetition type, etc.

[0127] The associated (type 1) CG PUSCH setting, the corresponding PUSCH reporting cell and / or BWP may be set for each periodic layer 1 CLI report of the PUSCH.

[0128] In the case where the periodicity and offset are explicitly set to the periodic layer 1 CLI report, the periodicity and offset of reporting PUSCH can be the same as the periodic layer 1 CLI report. In other cases, the reporting periodicity and offset of the periodic layer 1 CLI report can follow the periodicity and offset of reporting PUSCH.

[0129] (Option 2): Semi-persistent layer 1 CLI reporting

[0130] Semi-persistent layer 1 CLI reporting may be reported via PUCCH and / or PUSCH. Activation or deactivation of semi-persistent layer 1 CLI reporting may be performed via DCI or MAC CE or both.

[0131] For example, semi-persistent layer 1 CLI reporting related to PUCCH can be activated / deactivated through MAC CE, and semi-persistent layer 1 CLI reporting related to PUSCH can be activated / deactivated through DCI.

[0132] The application time of activation / deactivation of semi-persistent layer 1 CLI reporting may be defined by 3GPP specifications, or may be set by RRC, or may be indicated by activation / deactivation DCI / MAC CE.

[0133] In case of semi-persistent Layer 1 CLI reported over PUCCH, the following actions may apply.

[0134] The PUCCH formats that can be used in semi-persistent CLI reporting may be defined by the specification or may be configured by RRC. For example, the PUCCH formats (PF) that can be used for PUCCH in semi-persistent layer 1 CLI may be only 2, 3, and 4.

[0135] The associated PUCCH resources, corresponding PUCCH reporting cells and / or BWPs may be configured via RRC and / or indicated by activating DCI / MAC CE.

[0136] • The reporting periodicity and / or offset may be set by RRC and / or indicated by activating DCI / MAC CE.

[0137] For example, the periodicity may be set by RRC. The initial CLIPUCCH offset may be indicated by activating DCI / MAC CE. Alternatively, both the periodicity and the offset may be set by RRC, or both may be indicated by activating DCI / MAC CE.

[0138] In case of semi-persistent Layer 1 CLI reported over PUSCH, the following actions may apply.

[0139] The allocation of PUSCH time domain and frequency domain and other transmission parameters may be set through RRC and / or may be indicated through the activation of MAC CE or DCI.

[0140] For example, some parameters (e.g., time domain allocation (e.g., PUSCH start codeword and length), frequency domain allocation (e.g., PRB start, number of PRBs, activation / inactivation of frequency hopping, frequency hopping parameters), MCS, power control parameters, precoding information, antenna port, spatial relationship information, path loss reference signal (RS), number of repetitions, PUSCH repetition type, etc.) can be set through RRC, and other parameters can be indicated by activating DCI / MAC CE.

[0141] • The associated (type 1 or type 2) CG PUSCH configuration, corresponding PUSCH reporting cell and / or BWP may be configured per semi-persistent layer 1 CLI reporting of PUSCH.

[0142] The reporting periodicity and / or offset may be configured by RRC (in the case of CLI reporting configuration or associated PUSCH configuration) and / or indicated by activating DCI / MAC CE. In addition, the above three examples on PUCCH may also be applied to PUSCH.

[0143] (Option 3): Aperiodic Layer 1 CLI reporting

[0144] Aperiodic reporting of layer 1 CLI may be reported via PUCCH or PUSCH, or both. Aperiodic reporting of layer 1 CLI may be triggered via DCI or MAC CE, or both.

[0145] For example, aperiodic layer 1 CLI reporting related to PUCCH may be triggered by MAC CE, and aperiodic layer 1 CLI reporting related to PUSCH may be triggered by DCI.

[0146] In case of aperiodic Layer 1 CLI reported over PUCCH, the following actions may be applied.

[0147] The PUCCH format that can be used in the aperiodic CLI report may be defined by the specification or may be set by RRC. For example, the PUCCH format (PF) that can be used for PUCCH in the aperiodic layer 1 CLI may be only 2, 3, 4.

[0148] The associated PUCCH resources, the corresponding PUCCH reporting cell and / or BWP may be configured via RRC and / or may be indicated by triggering a DCI / MAC CE.

[0149] • The DCI / MAC CE used as a trigger may indicate the slot / sub-slot offset between the CLIPUCCH and the DCI / MAC CE used as a trigger.

[0150] In case of aperiodic Layer 1 CLI reported over PUSCH, the following actions may be applied.

[0151] • The DCI / MAC CE used as a trigger may indicate the slot / sub-slot offset between the CLIPUSCH and the DCI / MAC CE used as a trigger.

[0152] The allocation of the time domain and frequency domain of the PUSCH and other transmission parameters can be set through RRC and / or can be indicated by triggering DCI / MAC CE.

[0153] For example, PUSCH parameters (e.g., time domain allocation (PUSCH start codeword and length), frequency domain allocation (e.g., start of PRB, number of PRBs, activation / inactivation of frequency hopping, parameters of frequency hopping), MCS, power control parameters, precoding information, antenna port, spatial relationship information, path loss reference signal (RS), number of repetitions, PUSCH repetition type, etc.) can be indicated by triggering DCI / MAC CE.

[0154] In case of Option 2 and Option 3, in order to activate / deactivate / trigger DCI or MAC CE, the following process may be performed.

[0155] Specifically, the DCI format (DCI Format) can be constructed as follows.

[0156] Existing DL / UL grant DCI Format using the existing RNTI (Radio Network Temporary Identifier)

[0157] • A new DCI field for activation / deactivation / triggering of layer 1 CLI reporting may be included.

[0158] Unused existing DCI fields of Layer 1 CLI (e.g. HPN, TCI / SRI, etc.) can report activation / deactivation / triggering when DCI does not schedule PDSCH / PUSCH, and use the combination of fields as “coded / non-coded CSI indication” verification such as “FDRA=all 0, TDRA=all 0, MCS=all 0, RV=all 0, NDI=all 0, etc.”

[0159] Existing DCI Format using the new RNTI

[0160] New DCI Format

[0161] In addition, MAC CE can be constructed as follows.

[0162] New MAC CE

[0163] Existing MAC CE

[0164] New octet

[0165] · Existing octet (reserved bits may be used to specify whether the MAC CE is interpreted as coded / non-coded indication).

[0166] (3.4) Action Example 2

[0167] The layer 1 CLI report related to PUCCH / PUSCH may include layer 1 CLI-RSSI and layer 1 SRS-RSRP.

[0168] (Alt 1): The reporting quantity of the CLI report is explicitly set for the CLI reporting configuration. For example, the candidate value of the parameter (ReportQuantity) of the CLI reporting configuration may be set to CLI-RSSI or SRS-RSRP (or both).

[0169] (Alt 2): As shown in Action Example 4, the report amount of the CLI report is implicitly determined by the measurement resources associated with the CLI report.

[0170] When the CLI report is associated with only the CLI-RSSI measurement resource, the CLI report may be set for layer 1 CLI-RSSI reporting.

[0171] When the CLI report is associated only with the SRS-RSRP measurement resource, the CLI report may be set for layer 1 SRS-RSRP reporting.

[0172] When the CLI report is associated with the measurement resources of both CLI-RSSI and SRS-RSRP, the CLI report may be used for reporting both layer 1 CLI-RSSI and layer 1 SRS-RSRP.

[0173] (Alt3): The reporting amount reported by the CLI is explicitly indicated by the activation / triggering of the DCI / MAC CE.

[0174] • May only be applied to semi-persistent or aperiodic Layer 1 CLI reporting.

[0175] • At the time of activation / triggering of DCI / MAC CE, the reported quantity may be displayed as CLI-RSSI or SRS-RSRP (or both).

[0176] (3.5) Action Example 3

[0177] The maximum number of measurement results / resources reported by the Layer 1 CLI report may be limited (e.g., a maximum number N). Here, N may be defined by 3GPP specifications, or set by RRC, or indicated by the start / trigger of DCI / MAC CE. In addition, N may also vary depending on the reporting amount.

[0178] (Option 1): The UE may report measurement results per measurement resource (and per beam).

[0179] (Example 1): When the number of associated measurement resources (or the total number of measurement results of associated measurement resources) is less than N, the UE may include all measurement results in the CLI report.

[0180] (Example 2): When the number of associated measurement resources (or the total number of measurement results of the associated measurement resources) is greater than N, the UE may select N measurement results from all measurement results for reporting.

[0181] N measurement resources / results based on the strongest / weakest CLI-RSSI / SRS-RSRP

[0182] N randomly selected measurement resources / results

[0183] For example, when N=2, the UE reports the measurement results of the first resource and the second resource in the kth report, reports the measurement results of the third resource and the fourth resource in the k+1th report, and so on. The N measurement resources / results may be in a cyclic manner.

[0184] (Example 3): When the number of measurement results above and below the threshold is less than N, the UE may report measurement results that exceed / below the threshold reported by the CLI. Here, the threshold may be defined by the 3GPP specification or set by RRC.

[0185] (Example 4): When the number of measurement results above and below the threshold is greater than N, the UE may select N measurement results from the measurement results above and below the threshold for notification.

[0186] N measurements based on the strongest / weakest CLI-RSSI / SRS-RSRP

[0187] N randomly selected measurement results

[0188] (Option 2): The UE may report maximum / minimum / average measurement results.

[0189] (Example 1): The UE may report the maximum / minimum / average measurement results of all measurement resources associated with the CLI report.

[0190] (Example 2): The UE may report the maximum / minimum / average value of all measurement results that exceed / below the threshold.

[0191] In case of option 1, multiple measurements can be sorted in one CLI report.

[0192] (Alt 1): The reported measurement results are sorted in ascending / descending order of the measurement resource index.

[0193] (Alt 2): The reported CLI-RSSI or SRS-RSRP, CLI-RSSI or SRS-RSRP measurement resource index (beam index) are sorted in ascending / descending order of RSSI results or SRS-RSRP results.

[0194] When the measurement results of both CLI-RSSI and SRS-RSRP are reported in the CLI report, any of the following methods may be applied.

[0195] The CLI-RSSI measurement results and the SRS-RSRP measurement results are summarized and arranged based on the CLI-RSSI or SRS-RSRP value.

[0196] The CLI-RSSI measurement results and the SRS-RSRP measurement results are sorted together with the CLI-RSSI measurement results before and after the SRS-RSRP measurement results.

[0197] Additionally, the format of the reported CLI-RSSI and / or SRS-RSRP values ​​may be as follows.

[0198] (Alt a): Reports the CLI-RSSI or SRS-RSRP measurement resource index (and beam index), CLI-RSSI or SRS-RSRP, and each CLI-RSSI or SRS-RSRP is set to an absolute value.

[0199] (Alt b): Report the CLI-RSSI or SRS-RSRP measurement resource index (and beam index), CLI-RSSI or SRS-RSRP, set the initial CLI-RSSI and / or SRS-RSRP value to an absolute value, and set the CLI-RSSI or SRS-RSRP values ​​other than the initial value to a relative value (for example, a ΔRSSI and / or ΔSRS-RSRP value indicating an offset from the first RSSI and / or the first SRS-RSRP value).

[0200] (Alt c): Report reference values, reporting the CLI-RSSI or SRS-RSRP measurement resource index (and beam index), CLI-RSSI or SRS-RSRP, and setting each CLI-RSSI or SRS-RSRP value to a relative value (e.g., a ΔRSSI or ΔSRS-RSRP value indicating an offset from a reference value).

[0201] (Alt d): Report one reference CLI-RSSI value and one reference SRS-RSRP value, report the CLI-RSSI or SRS-RSRP measurement resource index (and beam index), CLI-RSSI or SRS-RSRP. Each CLI-RSSI or SRS-RSRP value is set to a relative value (for example, a ΔRSSI value indicating an offset from a reference CLI-RSSI value, or a ΔSRS-RSRP indicating an offset from a reference SRS-RSRP value).

[0202] (Notation): The absolute value can be set to an m-bit value in the range [a, b] dBm and c dB step size. Here, the CLI-RSSI / SRS-RSRP bit length m, the lower limit a and upper limit b, and the step size c can be defined by the 3GPP specification or can be set by RRC.

[0203] For example, in the range [-100, -25] dBm, a 7-bit value with a 1 dB step size may be set relative to CLI-RSSI as in the current specification.

[0204] The relative value is set to an n-bit value in the range [a1, b1] dBm and a c1 dB step size. The CLI-RSSI / SRS-RSRP bit length n, the lower limit a1 and the upper limit b1, and the step size c1 may be defined by the 3GPP specification or may be set by RRC.

[0205] (3.6) Action Example 4

[0206] For each Layer 1 CLI report, the associated measurement resource (or resource set) may be set via RRC, or indicated by activating a DCI / MAC CE, or may be implicitly determined as all “possible Layer 1 CLI-RSSI and / or Layer 1 SRS-RSRP measurement resources (or resource sets)”.

[0207] (Option 1): One or more resources (or resource sets) of "usable layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets)" may be set for each layer 1 CLI report.

[0208] (Example a): RRC configures the associated layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) for each layer 1 CLI report, and the UE measures the layer 1 CLI-RSSI and / or layer 1 SRS-RSRP on the associated measurement resources.

[0209] (Example b): Activating the DCI / MAC CE may indicate a layer 1 CLI-RSSI resource or a layer 1 SRS-RSRP resource (or resource set) to be measured.

[0210] (Option 2): The UE may measure layer 1 CLI-RSSI and / or layer 1 SRS-RSRP for all “possible layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets)”.

[0211] (Modification example): The maximum number of measurement resources associated with one layer 1 CLI report may be defined by the 3GPP specification.

[0212] In the associated measurement resource (or resource set), the UE may calculate a layer 1 CLI-RSSI value or a layer 1 SRS-RSRP value based on the measurement resource.

[0213] (Alt 1): In the latest resource in the associated measurement resource, the end slot may be within slot / sub-slot nk (where slot / sub-slot n is the layer 1 CLI report slot / sub-slot and k is the slot offset), or the end symbol may be set to be within k symbols before the first symbol of the layer 1 CLI report.

[0214] (Alt 2): It is up to the UE implementation to determine the following measurement resources in the associated measurement resources, where the end slot is within slot / sub-slot nk (slot / sub-slot n is the slot / sub-slot of the Layer 1 CLI report, and k is the slot offset), or the end symbol is a symbol within k symbols before the first symbol of the Layer 1 CLI report.

[0215] Figure 8 An example of the structure of measurement resources in action example 4 is shown. In the case of Alt 1 and Alt 2, the value of k is defined by the 3GPP specification, or is set by RRC, or is reported by the UE as capability signaling. It may also be determined based on the CLI processing time of layer 1.

[0216] The value k may be interpreted based on the SCS of the layer 1 CLI reporting cell, or based on the SCS of the cell of the associated measurement resources, or based on the minimum / maximum value of the SCS of the layer 1 CLI reporting cell and the SCS of the cell of the associated measurement resources.

[0217] Whether to apply Alt 1 or Alt 2 can be determined by the RRC structure (for example, each layer 1 CLI report setting, each layer 1 CLI report setting group, or each UE setting explicit parameters), or it can be indicated by the start / trigger of DCI / MAC CE, or it can be indicated by the 3GPP specification.

[0218] In the case of layer 1 CLI-RSSI measurement and reporting, the "possible layer 1 CLI-RSSI resources (or resource sets)" can be set to existing CLI-RSSI measurement resources (in the case of layer 3 measurement), ZP-CSI-RS resources (sets) or newly set layer 1 CLI-RSSI measurement resources (or resource sets).

[0219] (Example 1): The CLI-RSSI measurement resources composed of the resources in RSSI-ResourceConfigCLI-r 16 or RSSI-ResourceListConfigCLI-r 16 can be set as possible layer 1 CLI-RSSI resources.

[0220] (Example 2): A new parameter may be added to RSSI-ResourceConfigCLI-r 16 to indicate whether the CLI-RSSI measurement resource targets "layer 1 measurement and reporting", "layer 3 measurement and reporting", or "measurement and reporting of both layer 1 and layer 3".

[0221] In the case of CLI-RSSI measurement resources, when "layer 1" or "both layer 1 and layer 3" is set, it becomes "possible layer 1 CLI-RSSI resource".

[0222] When the UE determines a CLI-RSSI measurement resource associated with CLI reporting, the UE may measure CLI-RSSI on that resource and generate a report based on layer 1 procedures. When "Layer 3" or "Both Layer 1 and Layer 3" is set in the CLI-RSSI measurement resource, the UE may measure CLI-RSSI on that resource and follow the layer 3 reporting procedures defined in 3GPP TS 38.321.

[0223] (Example 3): Any CLI-RSSI measurement resource set by RSSI-ResourceConfigCLI-r 16 or any ZP-CSI resource set by ZP-CSI-Resource can be set as "Possible Layer 1 CLI-RSSI Resource".

[0224] (Example 4): A new parameter may be added to ZP-CSI-Resource or ZP-CSI-ResourceSet to indicate whether the ZP-CSI resource (set) is used for layer 1 CLI-RSSI measurement and reporting or for conventional use.

[0225] When "Layer 1 Measurement and Reporting" is set, it can be set to "Possible Layer 1 CLI-RSSI Resources (Set)".

[0226] (Example 5): Dedicated configuration of CLI-RSSI measurement resources (and resource sets) dedicated to Layer 1 CLI-RSSI measurement and reporting

[0227] • The time domain behavior of a dedicated layer 1 CLI-RSSI measurement resource or resource set may be periodic, semi-continuous or aperiodic.

[0228] The parameters required for layer 1 CLI-RSSI measurement resource configuration can reuse the parameters in ZP-CSI-RS-Resource (e.g., resourceMapping, periodityAndOffset, etc.) or the parameters in RSSI-ResourceConfigCLI-r 16.

[0229] In the case of layer 1 SRS-RSRP measurement and reporting, the "possible layer 1 SRS-RSRP resources (or resource sets)" can be set to existing SRS-RSRP measurement resources (for layer 3 measurements) or newly set layer 1 SRS-RSRP measurement resources (or resource sets).

[0230] (Example 1): The SRS resource set in SRS-ResourceConfigCLI-r 16 or SRS-ResourceListConfigCLI-r 16 may be set to "Possible layer 1 SRS-RSRP resource".

[0231] (Example 2): A new parameter may be added to SRS-ResourceConfigCLI-r 16 to indicate whether the SRS-RSRP measurement resource targets "layer 1 measurement and reporting", "layer 3 measurement and reporting", or "measurement and reporting of both layer 1 and layer 3".

[0232] In the case of SRS-RSRP measurement resources, if "Layer 1" or "Both Layer 1 and Layer 3" is set, it can be set to "Possible Layer 1 SRS-RSRP resources". When the UE determines the SRS-RSRP measurement resource associated with the CLI report, the UE can measure SRS-RSRP on this resource and generate a report based on the Layer 1 process.

[0233] When "Layer 3" or "Both Layer 1 and Layer 3" is set in the SRS-RSRP measurement resource, the UE can measure SRS-RSRP on the resource and follow the Layer 3 reporting procedure defined in 3GPP TS 38.321.

[0234] When "Layer 1 Measurement and Reporting" is set, it can be set to "Possible Layer 1 CLI-RSSI Resources (Set)".

[0235] (Example 3): Dedicated configuration of SRS-RSRP measurement resources (and resource sets) dedicated to layer 1 SRS-RSRP measurement and reporting

[0236] • The time domain behavior of a dedicated layer 1 SRS-RSRP measurement resource or resource set can be periodic, semi-persistent or aperiodic.

[0237] The parameters required for the layer 1 SRS-RSRP measurement resource structure can reuse the parameters of SRS-ResourceConfigCLI-r16.

[0238] Regarding activation / triggering of layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets), it may be performed as follows.

[0239] (Alt 1): When periodic Layer 1 CLI reporting is configured, semi-continuous Layer 1 CLI reporting is activated, or aperiodic Layer 1 CLI reporting is triggered, the associated Layer 1 CLI-RSSI and / or Layer 1 SRS-RSRP measurement resources (or resource sets) are activated / triggered.

[0240] • When layer 1 CLI reporting is deactivated, the associated layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) may be deactivated.

[0241] (Alt 2): Detach activation from CLI report settings / activation.

[0242] • Periodic layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) may be always activated.

[0243] · Semi-persistent layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) may be activated / deactivated by DCI or MAC CE (may be activated independently of the activation of CLI reporting). The application time of the semi-persistent CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) may be defined by 3GPP specifications, or may be set by RRC, or may be indicated by activation / deactivation of DCI / MAC CE.

[0244] Aperiodic layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) may be triggered by a DCI or MAC CE (the DCI / MAC CE may be triggered independently of the CLI report trigger). The triggered DCI / MAC CE may indicate a slot / subslot offset between the layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets) and the triggered DCI / MAC CE.

[0245] In addition, in Action Example 1, the DCI format (DCIFormat) or MAC CE that describes the activation / deactivation / triggering of the CLI report can be reused for the activation / triggering of the layer 1 CLI-RSSI and / or layer 1 SRS-RSRP measurement resources (or resource sets).

[0246] (3.7) Action Example 5

[0247] Beam-specific Layer 1 CLI measurements and reporting may be supported as follows.

[0248] (Option 1): The beam (e.g., TCI state, QCL type of DRS, or spatial relationship) can be set per layer 1 CLI measurement resource (set), or can be indicated by the activation DCI / MAC CE of the layer 1 CLI measurement resource (set).

[0249] (Option 2): Beams (e.g., TCI status, QCL type of DRS, or spatial relationship) may be set per layer 1 CLI report, or may be indicated by an activation DCI / MAC CE of a layer 1 CLI report.

[0250] (Example 1): The activation / triggering DCI reported by the layer 1 CLI may indicate a beam list (e.g., a list of TCI states, or QCL-type D RS, or a spatial relationship). Each beam in the list may be applied to 1 layer 1 CLI measurement resource (set) of the associated measurement resource (or resource set). In the case where the beam is applied to 1 resource set, the beam may be applied to each resource within the resource set.

[0251] (Example 2): The Activation / Triggers DCI reported by the Layer 1 CLI indicates a beam (e.g., TCI status, or QCL-type D RS, or spatial relation), which can be applied to each associated Layer 1 CLI measurement resource (set).

[0252] (Example 3): The activation / trigger DCI reported by Layer 1 CLI may represent a beam list (e.g., a list of TCI states, or QCL-type DRS, or spatial relationships) of Layer 1 CLI measurement resources (sets) associated with each beam in the list.

[0253] When the beam list is applied to one resource, it may indicate that the UE measures multiple beams on the resource.

[0254] When the beam list is applied to one resource, it may mean that the UE measures multiple beams for each resource in the resource set, or the UE measures one beam in the beam list for one resource in the resource set.

[0255] (3.8) Change examples

[0256] Whether the measured layer 1 CLI-RSSI or layer 1 SRS-RSRP is converted to layer 3 filtering can be defined by 3GPP specifications, RRC settings, or layer 1 measurement reports that trigger DCI / MAC CE.

[0257] In addition, independent layer 1 CLI reports can be set for XDD time units and non-XDD time units. Similarly, independent layer 1 CLI measurement resources can be set for XDD time units and non-XDD time units. Layer 1 CLI reports can also be applied to subband CLI reports.

[0258] The above actions may be set by higher layer parameters, reported by the UE as UE capabilities (capability(-ies)), or defined by 3GPP specifications. Alternatively, they may be determined by the setting of higher layer parameters and reported UE capabilities (a combination of the above determinations).

[0259] Regarding UE capability information (UE Capability Information), it can also be defined as follows.

[0260] Supports measurement and reporting of Layer 1 CLI-RSSI and / or SRS-RSRP in specific frequency ranges (e.g. FR1, FR2-1, FR2-2)

[0261] Whether layer 1 CLI-RSSI and / or SRS-RSRP measurements are supported, as well as support for licensed or unlicensed spectrum reporting

[0262] Support for periodic, semi-continuous and / or aperiodic Layer 1 CLI-RSSI and / or SRS-RSRP reporting

[0263] Support for Layer 1 CLI-RSSI and / or SRS-RSRP reporting for PUCCH / PUSCH

[0264] Support for dedicated layer 1 CLI-RSSI and / or SRS-RSRP measurement resource settings

[0265] Beam-property 1 CLI-RSSI and / or SRS-RSRP reporting support

[0266] (4) Action and Effect

[0267] According to the above-mentioned implementation, the following effects can be obtained. Specifically, UE 200 can periodically, semi-continuously or aperiodically send a report of the measured inter-link interference (CLI) in the lower layer (layer 1) to the network. Therefore, a CLI that is shorter than the higher layer (layer 3) can be reliably reported to the network. As a result, even in the case of extended duplex modes such as XDD, appropriate CLI can be provided, and more appropriate scheduling can be achieved.

[0268] (5) Other Implementation Methods

[0269] Although the present invention has been described above based on the embodiments, the present invention is not limited to these descriptions, and it is obvious to those skilled in the art that various modifications and improvements can be made.

[0270] For example, in the above-mentioned embodiment, the CLI between the gNB 100 and the UE 200 is described, but any device may be replaced with a node (e.g., an IAB host, an IAB node) constituting an IAB (Integrated Access and Backhaul).

[0271] Furthermore, in the above description, configure, activate, update, indicate, enable, specify, and select may be used interchangeably. Similarly, link, associate, correspond, and map may be used interchangeably, and allocate, assign, monitor, and map may be used interchangeably.

[0272] Furthermore, specific, dedicated, UE-specific, and UE-dedicated may be used interchangeably. Similarly, common, shared, group-common, UE-common, and UE-shared may be used interchangeably.

[0273] In the present disclosure, terms such as "precoding", "precoder", "weight (precoding weight)", "quasi-co-location (QCL: Quasi-Co-Location)", "Transmission Configuration Indication state (TCI state)", "spatial relationship (spatial relation)", "spatial domain filter (spatial domain filter)", "transmission power", "phase rotation", "antenna port", "antenna port group", "layer", "number of layers", "rank", "resource", "resource set", "resource group", "beam", "beam width", "beam angle", "antenna", "antenna element", and "panel" can be used interchangeably.

[0274] In addition, the block structure diagram ( Figure 4) represents a module in units of functions. These functional blocks (structural parts) are implemented by any combination of at least one of hardware and software. In addition, there is no particular limitation on the implementation method of each functional block. That is, each functional block can be implemented using a device that is physically or logically combined, or two or more physically or logically separated devices can be directly or indirectly connected (for example, using wires, wirelessly, etc.) and implemented using these multiple devices. The functional blocks can also be implemented by combining software in the above-mentioned one device or the above-mentioned multiple devices.

[0275] Functions include judging, determining, judging, calculating, calculating, processing, deriving, investigating, searching, confirming, receiving, sending, outputting, accessing, solving, selecting, selecting, establishing, comparing, assuming, expecting, regarding, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, assigning, etc., but are not limited to these. For example, a functional block (structural unit) that performs a sending function is called a transmitting unit or a transmitter. In short, as mentioned above, there is no particular limitation on the implementation method.

[0276] Furthermore, the above-mentioned gNB 100 and UE 200 (the device) can also function as computers that process the wireless communication method disclosed in the present invention. Fig. 9 FIG. 1 is a diagram showing an example of the hardware structure of the device. Fig. 9 As shown, the device may also be configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, and the like.

[0277] In the following description, the word "device" may be replaced by "circuit", "device", "unit", etc. The hardware structure of the device may include one or more of the devices shown in the figure, or may exclude some of the devices.

[0278] Each functional block of the device (refer to Figure 4 ) is implemented by any hardware element in the computer device, or a combination of such hardware elements.

[0279] In addition, each function in the device is implemented by the following method: predetermined software (program) is read into hardware such as processor 1001 and memory 1002, so that processor 1001 performs calculations and controls the communication of communication device 1004 or controls at least one of the reading and writing of data in memory 1002 and storage 1003.

[0280] The processor 1001 controls the entire computer by, for example, running an operating system. The processor 1001 may be composed of a central processing unit (CPU) including an interface with peripheral devices, a control device, a calculation device, registers, and the like.

[0281] In addition, the processor 1001 reads a program (program code), a software module, data, etc. from at least one of the memory 1003 and the communication device 1004 to the memory 1002, and performs various processes accordingly. As a program, a program that causes a computer to perform at least a part of the actions described in the above embodiments is used.

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

[0287] In addition, the processor 1001 and the memory 1002 and other devices are connected via a bus 1007 for communicating information. The bus 1007 may be configured by a single bus or may be configured by different buses between devices.

[0288] Furthermore, the device may be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), and a field programmable gate array (FPGA), and a part or all of each functional block may be implemented by the hardware.

[0289] In addition, the notification of information is not limited to the form / implementation method described in the present disclosure, and other methods may also be used. For example, the notification of information may 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., RRC signaling, medium access control (Medium Access Control: MAC) signaling, broadcast information (Master Information Block: MIB, System Information Block: SIB)), other signals or a combination thereof. In addition, RRC signaling may also be referred to as an RRC message, for example, an RRC connection creation (RRC Connection Setup) message, an RRC connection reconfiguration (RRC Connection Reconfiguration) message, etc.

[0291] The processing procedures, timings, processes, etc. of each form / implementation described in this disclosure may be changed in order without contradiction. For example, for the method described in this disclosure, the elements of various steps are presented in an illustrative order, but are not limited to the specific order presented.

[0292] In the present disclosure, specific actions performed by a base station are sometimes also performed by its upper node according to the situation. In a network composed of one or more network nodes having a base station, various actions performed to communicate with a terminal can be performed by at least one of the base station and other network nodes other than the base station (for example, MME or S-GW, etc., but not limited to these). In the above, the case where there is one other network node other than the base station is illustrated, but it can also be a combination of multiple other network nodes (for example, MME and S-GW).

[0293] Information, signals (information, etc.) can be output from a higher layer (or lower layer) to a lower layer (or higher layer). It can also be input or output via multiple network nodes.

[0294] The input or output information can be stored in a specific location (e.g., memory) or managed using a management table. The input or output information can be rewritten, updated, or appended. The output information can also be deleted. The input information can also be sent to other devices.

[0295] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value (Boolean: true or false), or by comparison of numerical values ​​(for example, comparison with a predetermined value).

[0296] Each form / implementation described in the present disclosure may be used alone or in combination, and may be switched depending on the execution. In addition, notification of predetermined information (e.g., notification of "yes X") is not limited to being performed explicitly, but may also be performed implicitly (e.g., not notifying the predetermined information).

[0297] Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or by other names, shall be interpreted broadly to refer to commands, sets of commands, codes, code segments, program codes, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0298] In addition, software, commands, information, etc. may be sent and received via a transmission medium. For example, when software is sent from a web page, 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.

[0299] The information, signals, etc. described in the present disclosure may also be represented by any of a variety of different technologies. For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc. that may be involved in the above description as a whole may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination of these.

[0300] In addition, the terms described in the present disclosure and the terms required for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, at least one of a channel and a symbol may also be a signal (signaling). In addition, a signal may also be a message. In addition, a component carrier (CC) may also be referred to as a carrier frequency, a cell, a frequency carrier, etc.

[0301] As used in this disclosure, the terms "system" and "network" are used interchangeably.

[0302] In addition, the information, parameters, etc. described in the present disclosure may be represented by absolute values, relative values ​​to predetermined values, or other corresponding information. For example, a wireless resource may be indicated by an index.

[0303] The names used for the above parameters are non-restrictive names in any respect. Furthermore, the formulas etc. using these parameters may sometimes differ from those explicitly disclosed in the present disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements may be identified by any appropriate names, and therefore the various names assigned to these various channels and information elements are non-restrictive names in any respect.

[0304] In the present disclosure, the terms "base station (BS)", "wireless base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", "component carrier" and the like are used interchangeably. Sometimes, the base station is also referred to as macro cell, small cell, micro-micro cell, micro-micro cell and the like.

[0305] A base station can accommodate one or more (e.g., 3) cells (also called sectors). When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, each of which can also provide communication services through a base station subsystem (e.g., a small base station for indoor use (Remote Radio Head: RRH)).

[0306] The terms "cell" or "sector" refer to a part or the entirety of a coverage area of ​​at least one of a base station and a base station subsystem that provide communication services within the coverage area.

[0307] In the present disclosure, the base station sending information to the terminal may be replaced by the base station instructing the terminal to perform control / action based on the information.

[0308] In the present disclosure, terms such as “mobile station (MS)”, “user terminal (user terminal)”, “user equipment (UE)”, and “terminal” may be used interchangeably.

[0309] For mobile stations, those skilled in the art sometimes also use the following terms: subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other appropriate terms.

[0310] At least one of the base station and the mobile station may also be referred to as a transmitting device, a receiving device, a communication device, etc. In addition, at least one of the base station and the mobile station may also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body may be a means of transportation (e.g., a car, an airplane, etc.), a mobile body that moves in an unmanned manner (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). In addition, at least one of the base station and the mobile station also includes a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0311] In addition, the base station in the present disclosure may also be replaced by a mobile station (user terminal, the same below). For example, various forms / implementations of the present disclosure may also be applied to a structure in which the communication between a base station and a mobile station is replaced by communication between multiple mobile stations (for example, may also be referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, it is also possible to set a structure in which the mobile station has the functions of the base station. In addition, terms such as "uplink" and "downlink" may also be replaced by terms corresponding to communication between terminals (for example, "side"). For example, an uplink channel, a downlink channel, etc. may also be replaced by a side channel (or side link).

[0312] Likewise, the mobile station in the present disclosure may be replaced by a base station. In this case, the base station may have the same functions as the mobile station.

[0313] A radio frame may be composed of one or more frames in the time domain. In the time domain, one or more frames may be referred to as a subframe. A subframe may also be composed of one or more time slots in the time domain. A subframe may be a fixed time length (e.g., 1 ms) that is independent of a numerology.

[0314] A parameter set may be a communication parameter applied to at least one of the transmission and reception of a certain signal or channel. The parameter set may, for example, 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 filtering process performed by a transceiver in the frequency domain, a specific windowing process performed by a transceiver in the time domain, and the like.

[0315] A slot may be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.) in the time domain. A slot may be a time unit based on a parameter set.

[0316] A time slot may contain multiple mini-slots. Each mini-slot may 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 be composed of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in units of time greater than a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may be referred to as a PDSCH (or PUSCH) mapping type B.

[0317] A radio frame, a subframe, a time slot, a mini-time slot, and a symbol all represent time units for transmitting signals. A radio frame, a subframe, a time slot, a mini-time slot, and a symbol may be referred to by other corresponding names.

[0318] For example, one subframe may be referred to as a transmission time interval (TTI), multiple consecutive subframes may be referred to as a TTI, and one time slot or one 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 (1ms) in existing LTE, a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. In addition, the unit representing a TTI may not be referred to as a subframe, but as a time slot, a mini time slot, or the like.

[0319] 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 the allocation of wireless resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) to each user terminal in units of TTI. In addition, the definition of TTI is not limited to this.

[0320] TTI can be a transmission time unit of data packets (transport blocks), code blocks, code words, etc. after channel coding, or a processing unit such as scheduling and link adaptation. In addition, when TTI is given, the time interval (e.g., the number of symbols) to which the transport block, code block, code word, etc. is actually mapped can be shorter than the TTI.

[0321] In addition, when one time slot or one 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 be the minimum time unit for scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit for scheduling can be controlled.

[0322] A TTI having a time length of 1 ms may also be referred to as a normal TTI (TTI in LTE Rel.8-12), a normal TTI, a long TTI, a normal subframe, a normal subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may also be referred to as a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini time slot, a sub time slot, a time slot, etc.

[0323] In addition, for a long TTI (longTTI) (for example, a normal TTI, a subframe, etc.), it can be replaced with a TTI having a time length exceeding 1ms, and for a short TTI (short TTI) (for example, a shortened TTI, etc.), it can be replaced with a TTI having a TTI length smaller than the long TTI (longTTI) and greater than 1ms.

[0324] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and in the frequency domain, may include one or more consecutive subcarriers.

[0325] The number of subcarriers included in an RB may be the same regardless of the parameter set, for example, may be 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0326] In addition, the time domain of an RB may include one or more symbols, and may be the length of one slot, one mini slot, one subframe, or one TTI. One TTI, one subframe, etc. may be composed of one or more resource blocks, respectively.

[0327] 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, and the like.

[0328] 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.

[0329] A bandwidth part (BandwidthPart: BWP) (also referred to as partial bandwidth, etc.) represents a subset of contiguous common RBs (common resource blocks: common resource blocks) for a parameter set in a certain carrier. Here, the common RB can be determined by the index of the RB based on the common reference point of the carrier. PRBs can be defined in a certain BWP and numbered within the BWP.

[0330] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0331] At least one of the set BWPs may be active, and it is not assumed that the UE transmits or receives a predetermined signal / channel outside the activated BWP. In addition, "cell", "carrier" and the like in the present disclosure may be replaced with "BWP".

[0332] The above structures of radio frames, subframes, time slots, mini-time slots, and symbols are merely 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, the cyclic prefix (CP) length, and the like may be changed in various ways.

[0333] The terms "connected", "coupled" or all variations of these terms are intended to indicate any direct or indirect connection or combination between two or more elements, and may include situations where there is one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be a physical combination or connection, a logical combination or connection, or a combination of these. For example, "access" may be used to replace "connection". In the context of the present disclosure, two elements may be considered to be "connected" or "coupled" to each other using at least one of one or more wires, cables, and printed electrical connections, and as some non-limiting and non-inclusive examples, electromagnetic energy having wavelengths in the wireless frequency domain, microwave region, and optical (visible and invisible) region may be used to "connect" or "couple" to each other.

[0334] The reference signal may be referred to as Reference Signal (RS) for short, or may be referred to as a pilot signal depending on the applicable standard.

[0335] The phrase “based on” used in the present disclosure does not mean “based only on” unless otherwise explicitly stated. In other words, the phrase “based on” means both “based only on” and “based at least on”.

[0336] The “unit” in the configuration of each of the above-mentioned devices may be replaced with a “section”, “circuit”, “device” or the like.

[0337] Any reference to an element using the designations "first," "second," etc. used in this disclosure does not necessarily limit the number or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, reference to the first and second elements does not mean that only two elements can be used there, or that the first element must precede the second element in some form.

[0338] When the terms "include", "including" and their variations are used in the present disclosure, these terms are intended to be inclusive like the term "comprising". Furthermore, the term "or" used in the present disclosure does not mean an exclusive or.

[0339] In the present disclosure, when an article is added by translation, such as a, an, and the in English, for example, the present disclosure also includes a case where the noun following the article is in a plural form.

[0340] The terms "determining" and "determining" used in the present disclosure sometimes also include a variety of actions. "Determining" and "determining" may include, for example, considering matters that have been judged, calculated, calculated, processed, derived, investigated, searched (for example, searched in a table, database or other data structure), confirmed (ascertaining) as matters that have been "judged" or "determined", etc. In addition, "determining" and "determining" may include matters that have been received (for example, receiving information), transmitted (for example, sending information), input, output, accessed (for example, accessed data in memory) as matters that have been "judged" or "determined", etc. In addition, "determining" and "determining" may include matters that have been resolved (resolving), selected (selecting), chosen (choosing), established (establishing), compared (comparing), etc. as matters that have been "judged" or "determined". That is, "judgment" and "decision" may include certain actions that are considered to be "judged" or "decided". In addition, "judgment (decision)" may also be replaced by "assuming", "expecting", "considering", etc.

[0341] In the present disclosure, the term "A and B are different" may mean "A and B are different from each other". In addition, the term may mean "A and B are different from C, respectively". The terms "separate" and "combined" may also be interpreted in the same way as "different".
