Description

Terminal, wireless communication method and base station

[0001] The present disclosure relates to a terminal, a wireless communication method, and a base station in a next-generation mobile communication system.

[0002] Long Term Evolution (LTE) has been specified for the Universal Mobile Telecommunications System (UMTS) network with the aim of achieving higher data rates and lower latency (Non-Patent Document 1). Also, LTE-Advanced (3GPP Rel. 10-14) has been specified with the aim of achieving higher capacity and more advanced features than LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9).

[0003] Successor systems to LTE (e.g., 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 or later, etc.) are also being considered.

[0004] 3GPP TS 36.300 V8.12.0 “Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 (Release 8)”, April 2010

[0005] Regarding future wireless communication technologies, the use of artificial intelligence (AI) technologies such as machine learning (ML) for network / device control and management is being considered.

[0006] For example, Channel State Information Reference Signal (CSI) feedback is being considered, which may use beam prediction.

[0007] However, there has been insufficient consideration of the definition of CSI in cases where beam prediction can be used. Without sufficient consideration, it may be impossible to achieve appropriate overhead reduction, highly accurate channel estimation, and highly efficient resource utilization, which may hinder improvements in communication throughput and communication quality.

[0008] Therefore, one of the objects of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can achieve suitable overhead reduction / channel estimation / resource utilization.

[0009] A terminal according to one aspect of the present disclosure has a receiving unit that receives a request for beam information for positioning the terminal's position, and a control unit that controls transmission of the beam information based on the request, and is characterized in that the beam information includes at least one of information indicating the beam direction of a reference signal, information indicating the power for each angle, information regarding an antenna reference point, information regarding the number of antenna ports, information regarding a reference signal transmitted using the same spatial domain filter, and information regarding an area to which the beam information is applicable.

[0010] According to one aspect of the present disclosure, it is possible to achieve favorable overhead reduction / channel estimation / resource utilization.

[0012] (CSI Report or Reporting) In Rel. 15 / 16 NR, a terminal (also referred to as a user terminal, User Equipment (UE), etc.) generates (also referred to as determining, calculating, estimating, measuring, etc.) channel state information (CSI) based on a reference signal (RS) (or a resource for the RS), and transmits (also referred to as reporting, feedback, etc.) the generated CSI to a network (e.g., a base station). The CSI may be transmitted to the base station using, for example, an uplink control channel (e.g., a Physical Uplink Control Channel (PUCCH)) or an uplink shared channel (e.g., a Physical Uplink Shared Channel (PUSCH)).

[0013] The RS used to generate the CSI may be, for example, at least one of a Channel State Information Reference Signal (CSI-RS), a Synchronization Signal / Physical Broadcast Channel (SS / PBCH) block, a Synchronization Signal (SS), a Demodulation Reference Signal (DMRS), etc.

[0014] The CSI-RS may include at least one of a non-zero power (NZP) CSI-RS and a CSI-Interference Management (CSI-IM). The SS / PBCH block is a block including an SS and a PBCH (and corresponding DMRS), and may be referred to as an SS block (SSB). The SS may include at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0015] The CSI may include at least one of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI-RS Resource Indicator (CRI), a SS / PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), L1-RSRP (Layer 1 Reference Signal Received Power), L1-RSRQ (Reference Signal Received Quality), L1-SINR (Signal to Interference plus Noise Ratio), L1-SNR (Signal to Noise Ratio), and the like.

[0016] The UE may receive information related to CSI reporting (report configuration information) and control CSI reporting based on the report configuration information. The report configuration information may be, for example, "CSI-ReportConfig" of an information element (IE) of Radio Resource Control (RRC). Note that in the present disclosure, the RRC IE may be interchangeably read as an RRC parameter, an upper layer parameter, or the like.

[0017] The reporting configuration information (e.g., "CSI-ReportConfig" of the RRC IE) may include, for example, at least one of the following: - Information on the type of CSI report (report type information, e.g., "reportConfigType" of the RRC IE) - Information on one or more quantities of CSI to be reported (one or more CSI parameters) (report quantity information, e.g., "reportQuantity" of the RRC IE) - Information on RS resources used to generate the quantities (the CSI parameters) (resource information, e.g., "CSI-ResourceConfigId" of the RRC IE) - Information on the frequency domain targeted for CSI reporting (frequency domain information, e.g., "reportFreqConfiguration" of the RRC IE)

[0018] For example, the report type information may indicate a periodic CSI (P-CSI) report, an aperiodic CSI (A-CSI) report, or a semi-persistent CSI (SP-CSI) report.

[0019] Furthermore, the reporting amount information may specify a combination of at least one of the above CSI parameters (for example, CRI, RI, PMI, CQI, LI, L1-RSRP, etc.).

[0020] In Rel. 17, the CRI / SSBRI fields are determined based on the number of CSI-RS resources or the number of SS / PBCH blocks in a resource set, respectively (see Figure 1).

[0021] In addition, in Rel. 17, the CSI report includes information on the CRI / SSBRI / L1-RSRP / L1-SINR and the corresponding panel. This information may be called Capability Index and has a bit width of 2 bits (see Figure 1).

[0022] (Application of Artificial Intelligence (AI) Technology to Wireless Communications) With regard to future wireless communications technologies, the use of AI technology such as machine learning (ML) for network / device control and management is being considered.

[0023] For example, for future wireless communication technologies, the use of AI techniques is being considered to improve channel state information (CSI) feedback (e.g., reduced overhead, improved accuracy, prediction), improve beam management (e.g., improved accuracy, prediction in the time / space domain), and improve positioning (e.g., improved position estimation / prediction).

[0024] 2 is a diagram illustrating an example of a framework for managing an AI model. In this example, each stage related to an AI model is shown as a block. This example is also referred to as lifecycle management of an AI model.

[0025] The data collection stage corresponds to a stage of collecting data for generating / updating an AI model. The data collection stage may include data organization (e.g., determining which data to transfer for model training / model inference), data transfer (e.g., transferring data to an entity (e.g., UE, gNB) that performs model training / model inference), etc.

[0026] In the model training stage, model training is performed based on the data (training data) transferred from the collection stage. This stage may include data preparation (e.g., performing data preprocessing, cleaning, formatting, transformation, etc.), model training / validation, model testing (e.g., verifying whether the trained model meets a performance threshold), model exchange (e.g., transferring the model for distributed learning), and model deployment / update (deploying / updating the model to the entity that will perform model inference).

[0027] In the model inference stage, model inference is performed based on the data (inference data) transferred from the collection stage. This stage may include data preparation (e.g., performing data preprocessing, cleaning, formatting, transformation, etc.), model inference, model monitoring (e.g., monitoring the performance of model inference), model performance feedback (feeding back model performance to the entity training the model), and output (providing model output to the actor).

[0028] An actor stage may include action triggers (e.g., deciding whether to trigger an action on another entity), feedback (e.g., feeding back information needed for training data / inference data / performance feedback), etc.

[0029] For example, training of a model for mobility optimization may be performed in, for example, Operation, Administration and Maintenance (Management) (OAM) / gNodeB (gNB) in a network (NW). In the former case, interoperability, large-capacity storage, operator manageability, and model flexibility (feature engineering, etc.) are advantageous. In the latter case, the latency of model updates and the need for data exchange for model deployment are advantageous. Inference of the above model may be performed in, for example, a gNB.

[0030] Also, depending on the use case, the entity that performs the training / inference may be different.

[0031] For example, for AI-assisted beam management based on measurement reports, the OAM / gNB may perform model training and the gNB may perform model inference.

[0032] For AI-assisted UE-assisted positioning, a Location Management Function (LMF) may perform model training and the LMF may perform model inference.

[0033] For CSI feedback / channel estimation using an autoencoder, the OAM / gNB / UE may perform model training and the gNB / UE may perform model inference (jointly).

[0034] For AI-assisted beam management or AI-assisted UE-based positioning based on beam measurements, the OAM / gNB / UE may perform model training and the UE may perform model inference.

[0035] Incidentally, it is desirable that data / AI models be treated as proprietary assets. For example, since creating a highly accurate AI model requires enormous costs and time, it would be a great disadvantage for a company if the contents of the AI ​​model created by a certain company were to become known to other companies. For this reason, it is being considered to make some of the information about the AI ​​model unavailable (or inferable) to UEs / gNBs provided by different vendors.

[0036] An identifier (ID)-based model approach can be one of the methods for managing AI models in such a scenario. For example, the NW / gNB does not know the details of the AI ​​model, but for AI model management, it can know only some information about the AI ​​model (e.g., which ML model is used in the UE and for what purpose).

[0037] 3 is a diagram showing an example of specifying an AI model. In this example, a UE and a NW (e.g., a base station (BS)) can recognize models #1 and #2 (although they do not need to fully understand the details of the models). The UE may report, for example, the capabilities of model #1 and model #2 to the NW, and the NW may instruct the UE on the AI ​​model to use.

[0038] <UE Positioning Using AI Technology> Fingerprinting localization, which estimates the location of wireless devices using the propagation characteristics of wireless signals, is widely used in both Line of Site (LOS) and Non-Line of Site (NLOS) scenarios.

[0039] In this disclosure, LOS may mean that the UE and base station are in an environment where they can see each other (or there are no obstructions), and NLOS may mean that the UE and base station are not in an environment where they can see each other (or there are obstructions).

[0040] Fingerprinting location estimates the UE's location based on a database / AI model from the fingerprints of the UE's multiple transmission paths (multipath).

[0041] The multipath information may be, for example, information regarding the Angle of Arrival (AoA) / Angle of Departure (AoD) of the signal for optimal / candidate transmission paths.

[0042] In the present disclosure, the information on AoA may include, for example, information on at least one of azimuth angles of arrival and zenith angles of arrival, and the information on AoD may include, for example, information on at least one of azimuth angles of departure and zenith angles of departure.

[0043] 3GPP Rel. 16 NR supports the following positioning technologies: DL / UL Time Difference Of Arrival (TDOA) based positioning, angle (DL AoD / UL AoA) based positioning, multi-Round Trip Time (RTT) based positioning, and Enhanced Cell ID (E-CID) based positioning.

[0044] FIG. 4 is a diagram showing an example of positioning based on DL / UL TDOA. For example, assume that a plurality of base stations (TRP#0-#2) are arranged around a UE. In this positioning method, the location of the UE is estimated (measured) using a measurement value of the Reference Signal Time Difference (RSTD). For example, the RSTD (T ｉ -T ｊ ) is a certain value (k ｉ，ｊ ) to draw a hyperbola H ｉ，ｊ The intersection of multiple such hyperbolas (H ０，１、 H １，２、 H ２，０ The location of the UE may be estimated by using the RSRP of the reference signal.

[0045] 5 shows an example of DL AoD / UL AoA-based positioning. In this positioning method, the UE's location is estimated using DL AoD measurements (e.g., θ or φ) or UL AoA measurements (e.g., θ or φ). The UE's location may also be estimated using RSRP.

[0046] 6 is a diagram showing an example of multi-RTT-based positioning. In this positioning method, the location of a UE is estimated using multiple RTTs calculated from the Tx / Rx time difference of reference signals (and additionally RSRP, RSRQ, etc.). For example, geometric circles based on the RTTs can be drawn with each base station at its center. The intersection of these multiple circles may be estimated as the location of the UE.

[0047] Figure 7 shows an example of E-CID based positioning, in which the UE's location is estimated based on the geometric location of the serving cell and additional measurements (Tx-Rx time difference, RSRP, RSRQ, etc.).

[0048] The positioning in the above-mentioned DL (DL TDOA, DL AoD) may be performed on the UE side or the LMF side. For example, in UE-based positioning, the UE may calculate the UE position based on various measurement results of the UE and assistance information from the LMF. In addition, in UE-assisted positioning, the UE may report various measurement results to the LMF, and the LMF may calculate the UE position. The assistance information may be information for assisting in estimating the UE's position.

[0049] The above-mentioned UL (UL TDOA, UL AoA) positioning may be performed on the LMF side. In this case, the base station may report various measurement results to the LMF, and the LMF may calculate the UE's position.

[0050] The above-mentioned positioning in DL and UL (multi-RTT, E-CID) may be performed on the LMF side. In this case, the UE / base station may report various measurement results to the LMF, and the LMF may calculate the UE's position.

[0051] Furthermore, in 3GPP Rel. 17, a positioning method using assist information is proposed for the purpose of further improving positioning accuracy. The assist information may be transmitted between the UE, the base station, and the LMF as measurement information for the above-mentioned DL / UL-TDOA, DL-AoD / UL-AoA, multi-RTT, and E-CID.

[0052] The assistance information may include information regarding at least one of the following: Timing Error Group (TEG); RSRPP (path-specific RSRP); Expected angle; Adjacent beam information; TRP antenna (location / configuration) / beam information; LOS / NLOS indicator; Additional path reports.

[0053] The TEG may indicate one or more Positioning Reference Signal (PRS) resources whose Rx / Tx timing errors are within a certain margin.

[0054] RSRPP may indicate the measurement result of RSRP on the first pass.

[0055] In UL positioning, the assistance information regarding the expected angle may indicate an expected UL-AoA / ZoA. The assistance information may be transmitted to the base station from an LMF. The assistance information may support at least one of UL TDOA, UL AoA, and multi-RTT positioning.

[0056] In DL positioning, the assistance information regarding the expected angle may include information regarding the expected DL-AoA / ZoA or DL-AoD / ZoD. The assistance information may be transmitted to the UE from the LMF. The assistance information may also support at least one of DL TDOA, DL AoA, and multi-RTT positioning. This improves the accuracy of angle-based UE positioning and enables optimization of Rx beamforming of the UE or base station.

[0057] The assist information regarding the predicted angles may include, in addition to the information on the values ​​of AoA / ZoA / AoD / ZoD themselves as described above, information indicating the range of uncertainty of these values.

[0058] As additional beam information, the neighboring beam information may include information about a subset of DL-PRS resources for the purpose of prioritizing DL-AoD reports (Option 1) or the boresight direction of each DL-PRS resource (Option 2), allowing for optimization of UE Rx beam sweeping and DL-AoD measurements.

[0059] As additional beam information, the assist information may also include PRS beam pattern information, which may include information regarding the relative power between DL-PRS resources for each angle for each TRP.

[0060] The LOS / NLOS indicator may indicate information regarding Line Of Site (LOS) / Non-Line Of Site (NLOS).

[0061] In addition, in order to improve the positioning delay of the UE, pre-configured measurement gaps (MG), activation of the MG via lower layers, MG-less location, PRS Rx / Tx in RRC_INACTIVE state, or on-demand PRS may be configured for the UE (or may be used by the UE).

[0062] Beam Information for UE Positioning As mentioned above, antenna (configuration) configuration / beam information is considered useful for AI / M1 models.

[0063] The following scenarios A and B are possible scenarios in which antenna (arrangement) setting / beam information is used.

[0064] [Scenario A] A more appropriate AI model is selected based on antenna settings / frequency / area.

[0065] [Scenario B] The AI ​​model requires metadata (antenna configuration information / beam information) as input to provide better performance.

[0066] Existing specifications support the use of assist information from the base station (gNB) beam information from the network (NW) to the UE only for positioning purposes.

[0067] The following are being considered for future wireless communication methods: - Using beam information for beam management. - Using beam information in interfaces other than positioning protocols (e.g., LTE Positioning Protocol (LPP)). - Using beam information of RSs other than positioning reference signals (PRSs) for positioning. - Using beam information in the UE.

[0068] In Rel. 17, beam information indicating the direction of a beam (boresight direction) for each PRS is supported as beam information from the LMF to the UE (beam information for UE-based positioning, information on a transmission beam from a base station). The beam information may be information indicating the boresight direction for each PRS.

[0069] The beam information indicating the direction of the beam for each PRS is "DL-PRS-BeamInfoElement" included in the common NR positioning information element "NR-DL-PRS-BeamInfo".

[0070] "DL-PRS-BeamInfoElement" includes information about the azimuth angle and elevation angle of the beam transmitted from the base station (TRP).

[0071] Information about the azimuth angle is "dl-PRS-Azimuth" and "dl-PRS-Azimuth-fine." "dl-PRS-Azimuth" is information expressed in units of 1 degree, with values ​​ranging from 0 to 359 degrees, and "dl-PRS-Azimuth-fine" is information expressed in units of 0.1 degrees, with values ​​ranging from 0 to 0.9 degrees.

[0072] Information about the elevation angle is "dl-PRS-Elevation" and "dl-PRS-Elevation-fine." "dl-PRS-Elevation" is information expressed in 1-degree increments and values ​​from 0 to 180 degrees, while "dl-PRS-Elevation-fine" is information expressed in 0.1-degree increments and values ​​from 0 to 0.9 degrees.

[0073] Furthermore, in Rel. 17, beam information indicating the relative power of DL PRS at each angle (azimuth angle / elevation angle) is supported as beam information from the LMF to the UE (beam information for UE-based positioning, information on the transmission beam of the base station).

[0074] The beam information indicating the relative power is included in the beam antenna information of the TRP in the common NR positioning information element ("NR-TRP-BeamAntennaInfo").

[0075] "NR-TRP-BeamAntennaInfo" includes information "NR-TRP-BeamAntennaInfoAzimuthElevation" regarding the beam antenna information of the TRP for azimuth and elevation angles.

[0076] "NR-TRP-BeamAntennaInfoAzimuthElevation" includes "azimuth" indicating the azimuth angle in 1° granularity, "azimuth-fine" indicating the azimuth angle in 0.1° granularity, and "elevationList" a list of elevation angles.

[0077] The elevation angle list "elevationList" includes "elevation" indicating the elevation angle in 1° granularity, "elevation-fine" indicating the elevation angle in 0.1° granularity, and a beam power list "beamPowerList".

[0078] The beam power list "beamPowerList" includes "nr-dl-prs-ResourceSetID" indicating the resource set ID of the DL PRS, "nr-dl-prs-ResourceID" indicating the resource ID of the DL PRS, "nr-dl-prs-RelativePower" indicating the relative power of the resource given by "nr-dl-prs-ResourceID" in 1 dB granularity, and "nr-dl-prs-RelativePowerFine" indicating the relative power of the resource given by "nr-dl-prs-ResourceID" in 0.1 dB granularity.

[0079] Furthermore, in Rel. 17, information indicating an antenna reference point (ARP) is supported as beam (antenna) information (information on the transmission beam of the base station) from the LMF to the UE.

[0080] This information is indicated by the "referencePoint" in "NR-TRP-LocationInfo", which is the location information of the TRP in the common NR positioning information element.

[0081] The TRP location information "NR-TRP-LocationInfo" is expressed by the relative positions between reference points.

[0082] The ARP location of a PRS resource is expressed as a relative location associated with the ARP location of the PRS resource set.

[0083] The antenna reference point is designated by altitude, latitude and longitude.

[0084] In addition, in Rel. 17, information regarding the spatial direction of DL PRS is supported as information from a base station (e.g., a gNB, a Next Generation Radio Access Network (NG-RAN) node) to an LMF (information regarding the transmission beam of the base station).

[0085] The information includes information indicating the azimuth and elevation boresight directions of the PRS resource.

[0086] The information also includes transition information from a local coordinate system (LCS) to a global coordinate system (GCS).

[0087] A GCS may be defined for a system including multiple base stations and multiple UEs, and an LCS may define an array antenna for one base station or one UE.

[0088] The LCS is used as a reference to define the vector far-field of each antenna element in the array. The vector far-field is a pattern and polarization. The placement of the array within the GCS may be defined by a transformation between the GCS and the LCS. The GCS / LCS may be derived, for example, based on definitions and transformation formulas (defined in the specification) that would be recognized by one skilled in the art.

[0089] In addition, Rel. 17 supports information indicating the beam / antenna of the TRP as information from a base station (e.g., a gNB) to an LMF (information regarding the transmission beam of the base station).

[0090] The information includes information indicating the relative power of the DL PRS at each angle (azimuth / elevation).

[0091] In addition, Rel. 17 supports information about the receiving beam when measuring a UL signal as information from a base station (e.g., a gNB) to an LMF (information about the receiving beam of the base station).

[0092] The information includes at least one of a PRS resource ID, a PRS resource set ID, and an SSB index.

[0093] Furthermore, Rel. 17 supports information about spatial relationships as information transmitted from a UE to a NW (information about a transmission beam of the UE).

[0094] The information indicates the ID / index of a particular RS (e.g., SSB / CSI-RS / SRS / DL PRS).

[0095] In addition, Rel. 17 defines the number of receiving beams for a UE in beam sweeping for positioning. A UE may report the support of its UE capabilities to the LMF.

[0096] For example, in FR1, the UE uses one receive beam.

[0097] In FR2, if the UE supports a specific UE capability, the number of beams indicated by the information "numberOfRxBeamSweepingFactor" indicating the number of Rx beam sweeping factors for FR2 is used. Otherwise, the UE uses eight receiving beams.

[0098] In addition, information regarding the receiving beam that the UE uses for measurements (e.g., "nr-DL-PRS-RxBeamIndex") is supported.

[0099] For this information, if different beams are used within a DL PRS resource set, the UE may report measurements received on the same receiving beam.

[0100] In other words, the beam information transmitted by the UE is information indicating whether the same beam is used between resource sets.

[0101] (Beam Prediction in Beam Management) In future wireless communication systems (for example, Rel. 18 and later), the introduction of beam management involving beam prediction is being considered.

[0102] Among beam predictions, spatial domain beam prediction, temporal domain beam prediction, and a combination of spatial domain beam prediction and temporal domain beam prediction are considered.

[0103] Spatial domain beam prediction and temporal domain beam prediction may be performed in the UE and / or the base station.

[0104] In spatial domain beam prediction, the UE / base station may input measurement results (beam quality, e.g., RSRP) based on sparse (or thick / wide) beams into an AI model, which may output dense (or thin / narrow) beam quality (see Figure 8A).

[0105] In time-domain (temporal) beam prediction, the UE / BS may input time-series (past, present, etc.) measurement results (beam quality, e.g., RSRP) into an AI model and output future beam quality (see Figure 8B).

[0106] In this disclosure, a sparse (or thick / wide) beam may refer to a beam (pattern) that is sparsely distributed in the spatial / angular domain, and a dense (or thin / narrow) beam may refer to a beam (pattern) that is densely distributed in the spatial / angular domain.

[0107] Incidentally, in future wireless communication systems (for example, Rel. 18 and later), it is being considered to transmit beam information / antenna information supported in the above-mentioned positioning to the UE by RRC signaling or the like.

[0108] In addition, when the AI / ML model is used in the NW (base station), it is being considered to report beam information from the UE side to the NW.

[0109] However, the configuration / control method of the beam information transmitted to the UE and the beam information transmitted by the UE has not been sufficiently considered. If these are not adequately considered, it may be impossible to achieve appropriate overhead reduction / high-precision channel estimation / high-efficiency resource utilization, and improvement of communication throughput / communication quality may be inhibited.

[0110] Therefore, the present inventors have devised a method for configuring / controlling suitable beam information. Note that each embodiment of the present disclosure may be applied when AI / prediction is not used.

[0111] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the drawings. Wireless communication methods according to the embodiments may be applied independently or in combination.

[0112] In the present disclosure, "A / B" and "at least one of A and B" may be interpreted interchangeably. Also, in the present disclosure, "A / B / C" may mean "at least one of A, B, and C."

[0113] In the present disclosure, terms such as activate, deactivate, indicate (or indicate), select, configure, update, and determine may be read interchangeably. In the present disclosure, terms such as support, control, controllable, operate, and operate may be read interchangeably.

[0114] In the present disclosure, Radio Resource Control (RRC), RRC parameters, RRC messages, higher layer parameters, fields, information elements (IEs), settings, etc. may be interchangeable. In the present disclosure, Medium Access Control (MAC) control elements (CEs), update commands, activation / deactivation commands, etc. may be interchangeable.

[0115] In the present disclosure, higher layer signaling may be, for example, any one of Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, LPP messages, etc., or a combination thereof.

[0116] In the present disclosure, MAC signaling may use, for example, a MAC Control Element (MAC CE), a MAC Protocol Data Unit (PDU), etc. Broadcast information may be, for example, a Master Information Block (MIB), a System Information Block (SIB), Remaining Minimum System Information (RMSI), Other System Information (OSI), etc.

[0138] The UE / NW may follow at least one of the following options 1-1-1 and 1-1-2.

[0139] [Option 1-1-1] The UE may request information about antennas / beams (which may be referred to as beam information) from the base station. In other words, the UE may transmit a request for beam information from the base station.

[0140] The request may be sent in accordance with the methods described in Appendix 3 below.

[0149] For example, the UE may transmit the request by transmitting a PRACH that includes a specific PRACH resource, or, for example, the UE may transmit the request by reporting UE capability information.

[0150] The UE may receive a response to the request from the NW.

[0151] The UE may receive the beam information after receiving the response, or may receive the beam information together with the response.

[0152] The UE may receive the response according to the method described in Supplementary Note 2 below.

[0153] The UE may assume that the response contains information indicating failure to detect / receive the request (option 1-1-1-1). The UE may also receive a response containing information indicating failure to detect / receive the request.

[0154] The information indicating failure to detect / receive the request may include information indicating one or more error causes / reasons, which may be predefined in a specification.

[0155] The reason for the error may be, for example, at least one of the following: failure to receive assistance information; failure to measure any TRP; attempting to measure neighboring cells but failing to do so; not having enough signals to measure the angle of the DL signal; failure to receive location calculation assistance information; and an undefined reason.

[0156] The UE may decide whether to retransmit the request or to abort sending the request based on the error reason indicated in the response.

[0157] The UE may assume that the beam information is included in the response (option 1-1-1-2). The UE may receive a response including the beam information.

[0158] If the UE does not receive the response for a specific period of time, the UE may determine that the NW has failed to receive the request (option 1-1-1-3). The UE may determine whether to resend the request to the NW or to cancel the transmission of the request based on a specific rule.

[0159] 9A is a diagram showing an example of a beam information reception process according to embodiment 1-1. In the example shown in FIG. 9A, the UE first transmits a beam information request to the NW (gNB) (step S901). Then, the UE receives a response to the request from the NW (gNB) (step S902) and receives the beam information.

[0160] [Option 1-1-2] In option 1-1-2, the UE does not need to send the request in option 1-1-1 above.

[0161] The UE may receive beam information according to at least one of options 1-1-2-1 to 1-1-2-3 below.

[0162] [[Option 1-1-2-1]] The UE may receive beam information based on the method described in Supplementary Note 2 below.

[0163] The beam information received by the UE may be UE-specific (dedicated) signaling.

[0164] The UE may receive beam information after reporting the corresponding UE capabilities to the NW.

[0165] Option 1-1-2-1 can improve resource utilization efficiency when many UEs do not require beam information.

[0166] [[Option 1-1-2-2]] The UE may receive the beam information using system information, in other words, the beam information may be included in the system information.

[0167] The system information may be, for example, SIB X (X is an arbitrary integer, for example, 1).

[0168] Option 1-1-2-2 can improve resource utilization efficiency when a large number of UEs require beam information.

[0169] [[Option 1-1-2-3]] The UE may receive the beam information using group-wide (multiple UE-wide) signaling. In other words, the beam information may be included in group-wide (multiple UE-wide) signaling.

[0170] The group-wide (multiple UE-wide) signaling may be, for example, a multicast / broadcast signal.

[0171] Signals to be broadcast (e.g., PDSCH, group-common PDCCH) may be scheduled, for example, in a DCI format for broadcast (DCI format 4_0).

[0172] A signal to be multicast (for example, a PDSCH or a group-common PDCCH) may be scheduled, for example, in a DCI format for multicast (DCI format 4_1 / 4_2).

[0173] Option 1-1-2-3 can improve resource utilization efficiency when a large number of UEs require beam information.

[0174] 9B is a diagram showing another example of the beam information reception process according to embodiment 1-1. In the example shown in FIG. 9B, the UE receives beam information from the NW (gNB) without transmitting a beam information request to the NW (gNB) (step S903).

[0175] <<Embodiment 1-2>> In embodiment 1-2, beam information transmitted from the NW to the UE will be described.

[0177] [Option 1-2-1] The beam information may include information indicating the direction (boresight direction) of the beam associated with the RS.

[0178] The information may be information indicating the angle of the direction (boresight direction) of the beam associated with the RS.

[0179] The angle may be, for example, an azimuth / elevation angle.

[0180] The angle may be the angle of the transmission beam at the base station / TRP.

[0181] [Option 1-2-2] The beam information may include information indicating the power (beam power) of the RS.

[0182] The power of the RS may be the absolute power of the RS or the relative power of the RS to a particular RS.

[0183] The information indicating the power of the RS may be information indicating the power of the RS for each angle.

[0184] The angle may be, for example, an azimuth / elevation angle.

[0185] The angle may be the angle of the transmission beam at the base station / TRP.

[0186] The power (beam power) of the RS may be expressed as the relative power between the RSs compared to the peak power at the corresponding angle.

[0187] The UE may determine an RS that achieves peak power for a corresponding angle based on a specific rule / parameter. For example, when power is expressed by a parameter on a sequence, the UE may determine an RS that corresponds to a specific element (e.g., the first element) as the RS that achieves peak power.

[0188] [Option 1-2-3] The beam information may include information about the antenna reference point (ARP) of the RS.

[0189] The information about the ARP may be, for example, information indicating the location of the ARP.

[0190] The information indicating the location of the ARP may be indicated by information indicating an absolute location (for example, altitude / latitude / longitude).

[0191] The ARP location may be the location of the ARP of the RS resource. The ARP location of the RS resource may be indicated by a relative location from at least one of the ARP of the RS resource set, the UE location, and the TRP location.

[0192] The ARP location may be the location of the ARP of the RS resource set. The ARP location of the RS resource set may be indicated by a relative location from at least one of a reference point, a UE location, and a TRP location. The reference point may be indicated by altitude / latitude / longitude.

[0194] At least one of the ARP position of the RS resource, the ARP position of the RS resource set, the TRP position, the UE position, and the reference point may be indicated by information indicating an absolute position, such as at least one of an ellipsoid point (optionally with altitude), a point on an uncertainty circle, a point on an uncertainty ellipse, and a point on an uncertainty ellipsoid.

[0195] [Option 1-2-4] The beam information may include information regarding the number of antenna ports.

[0196] The information regarding the number of antenna ports may be, for example, at least one of information regarding the total number of antenna ports, information regarding the number of antenna ports per angle, information regarding the total number of antenna panels, information regarding the number of antenna panels per angle, information regarding the distance between antenna ports (per angle), and information regarding the distance between antenna panels (per angle).

[0197] Information regarding the number of antenna ports may be specified / configured for each RS resource / each RS resource set.

[0198] [Option 1-2-5] The beam information may include information about RSs transmitted using the same spatial domain filter / beam.

[0199] The information about RSs transmitted using the same spatial domain filter / beam may be, for example, information indicating a mapping / correspondence relationship between beams (beam-related parameters).

[0200] In the present disclosure, relative relationships of beams, specific QCL types (e.g., QCL type D (spatial reception parameters)), spatial relationships, etc. may be read interchangeably.

[0201] For example, if multiple RSs correspond (map) to the same beam relative relationship, the UE may assume / determine that at least one of the boresight direction of the RSs and the (absolute / relative) power of the RSs per angle is the same.

[0202] Option 1-2-5 can reduce the overhead associated with reporting beam information.

[0203] [Option 1-2-6] The beam information may include information about the area.

[0204] The information about the area may be, for example, information indicating the area in which the corresponding beam information is valid.

[0205] The information indicating the area in which the corresponding beam information is valid may include at least one of the following information (list of information): Area ID. Cell global ID (in NR). Physical cell ID (Identifier) ​​(in NR). Absolute Radio Frequency Channel Number (ARFCN). Evolved Cell Global ID (ECGI).

[0206] The information regarding the area ID may include at least one of the global ID of the NR cell, the physical cell ID of the NR, and the ARFCN.

[0207] The UE may be provided with a list of area IDs corresponding to the assistance data from the LMF / base station in the assistance data. The list of area IDs may be a list of cell IDs (information including at least two of the global ID of the cell (NR), the physical cell ID (NR), and the ARFCN).

[0208] According to option 1-2-6, for example, when the antenna configuration of the base station is the same, the same beam information can be applied to different cells, thereby reducing signaling overhead.

[0209] A specific index may be assigned to at least one of the information items in Options 1-2-1 to 1-2-6. The assignment may be specified in advance in a specification, or may be notified from the UE to the NW based on the method described in Supplementary Note 3 below, or may be notified from the NW to the UE based on the method described in Supplementary Note 2 below.

[0210] This allows beam information based on an index (that can be identified by an index) to be realized in the UE / NW, thereby reducing signaling overhead.

[0211] Variations of the First Embodiment In the present disclosure, information about angles may be expressed in a particular way.

[0212] For example, in this disclosure, angles may be expressed at multiple scales.

[0213] For example, the angle may be expressed as an azimuth angle and an elevation angle. The azimuth angle / elevation angle may be determined based on certain parameters.

[0214] The parameter indicating the azimuth angle / elevation angle may be expressed by a plurality of different parameters according to the granularity.

[0215] For example, a parameter indicating an azimuth angle / elevation angle may be expressed as a first parameter expressed at a first granularity (e.g., in units of 1°) and a second parameter expressed at a second granularity (e.g., in units of 0.1°).

[0216] Also, for example, in this disclosure, angles may be expressed / displayed in LCS / GCS.

[0217] For example, azimuth / elevation angles may be expressed / displayed in LCS / GCS.

[0218] If the angle is expressed in LCS, information for conversion between LCS and GCS may be signaled / provided to the UE / NW.

[0219] If no information for such conversion is provided, the UE / NW may assume that angles are expressed / displayed in GCS.

[0295] For example, the bit width is, for example, ceil(log ２ (N)), where N may be the number of SRS resources in the associated SRS resource set. In the present disclosure, ceil(X) may mean multiplying X by a ceiling function.

[0296] The RS resource indicator / RS resource set indicator may be reported together with the panel index (CapabilityIndex).

[0297] 11A and 11B are diagrams illustrating an example of a beam report according to embodiment 3-1. The examples illustrated in Fig. 11A and 11B illustrate a case in which an RS resource indicator is reported together with a panel index (CapabilityIndex) in a beam report (CSI report).

[0298] 11A shows the bit width of the information included in the beam report. The number of bits (X) of the RS resource indicator may be determined based on the above method.

[0299] 11B, information included in a beam report is described. The beam report includes CRI or SSBRI (#1-#4), RSRP (RSRP#1) corresponding to CRI or SSBRI#1, differential RSRP (differential RSRP#2-#4) corresponding to CRI or SSBRI#2-#4, panel index (CapabilityIndex) #1-#4 corresponding to each of CRI or SSBRI#1-#4, and RS resource indicator #1-#4 corresponding to each of CRI or SSBRI#1-#4.

[0300] 11B illustrates an example in which a beam report includes multiple RS resource indicators, i.e., RS resource indicators corresponding to each CRI or SSBRI. However, the beam report may include only one RS resource indicator. In this case, the one RS resource indicator may correspond to each CRI or SSBRI. Whether the beam report includes an RS resource indicator corresponding to each CRI or SSBRI or includes only one RS resource indicator may be determined based on higher layer signaling.

[0301] In addition, the RS resource indicator / RS resource set indicator may be reported separately from the panel index (CapabilityIndex).

[0302] 12A and 12B are diagrams showing another example of a beam report according to embodiment 3-1. The examples shown in Fig. 12A and 12B describe a case in which an RS resource indicator is reported separately from a panel index (Capability Index) in a beam report (CSI report).

[0303] 12A and 12B differ from FIGS. 11A and 11B only in that information about the panel index (CapabilityIndex) is not included.

[0304] In this way, by reporting information about RS resources together with the CSI (L1-RSRP / SINR) report, if beam information related to the SRS resource is available, information about the receiving beam used for measurement can be reported to the network.

[0305] The receive beam information may also be, for example, a beam index.

[0306] The beam index may be, for example, the index of the UE's receive beam / spatial domain receive filter used for the corresponding measurement.

[0307] For example, if the UE uses the same beam to receive a signal in a measurement, the same beam index may be reported.

[0308] If the UE uses the same (or different) beam in the measurement, it may decide to include the beam index in the beam report and send it.

[0309] The bit width of the reported beam index field may be determined based on certain rules / parameters.

[0310] For example, the bit width is, for example, ceil(log ２ (M)), where M may be a number indicated by the receive beam sweeping factor of the UE.

[0311] For example, the bit width may be determined separately for each frequency range (for example, FR1 / FR2 (FR2-1 / FR2-2) / FR3 / FR4 / FR5).

[0312] The beam index may be reported along with the panel index (CapabilityIndex).

[0313] 13A and 13B are diagrams showing another example of a beam report according to embodiment 3-1. The examples shown in Fig. 13A and 13B describe a case in which a receive beam index (RxbeamIndex) is reported together with a panel index (CapabilityIndex) in a beam report (CSI report).

[0314] The example shown in Figure 13A shows the bit width of the information included in the beam report. The number of bits (X) of the receive beam index may be determined based on the above method.

[0315] 13B, information included in the beam report is described. The beam report includes CRI or SSBRI (#1-#4), RSRP (RSRP#1) corresponding to CRI or SSBRI#1, differential RSRP (differential RSRP#2-#4) corresponding to CRI or SSBRI#2-#4, panel index (CapabilityIndex) #1-#4 corresponding to each of CRI or SSBRI#1-#4, and receive beam index #1-#4 corresponding to each of CRI or SSBRI#1-#4.

[0316] 13B shows an example in which a beam report includes multiple receive beam indexes, i.e., receive beam indexes corresponding to each CRI or SSBRI. However, the beam report may include only one receive beam index. In this case, the one receive beam index may correspond to each CRI or SSBRI. Whether the beam report includes a receive beam index corresponding to each CRI or SSBRI or includes only one receive beam index may be determined based on higher layer signaling.

[0317] In addition, the receive beam index may be reported separately from the panel index (CapabilityIndex).

[0318] 14A and 14B are diagrams showing another example of a beam report according to embodiment 3-1. The examples shown in Fig. 14A and 14B describe a case in which a receiving beam index is reported separately from a panel index (Capability Index) in a beam report (CSI report).

[0319] 14A and 14B differ from FIGS. 13A and 13B only in that information about the panel index (CapabilityIndex) is not included.

[0320] If the panel index (CapabilityIndex) corresponding to the reported result is different, the UE / NW may assume / determine that a different beam / spatial domain filter corresponds even if the beam index corresponding to the reported result is the same.

[0321] In this way, by reporting the beam index together with the CSI (L1-RSRP / SINR) report, the beam can be reported using a mechanism similar to the signal measurement in the beam (L1-RSRP / SINR) measurement, thereby simplifying the implementation of the UE.

[0322] <<Embodiment 3-2>> The UE may report information about the receiving beam (receiving beam information).

[0323] The UE may report the receiving beam information along with signal measurement information for positioning related to DL measurements.

[0324] The positioning may be, for example, at least one of NR E-CID based positioning, DL-TDOA based positioning, DL-AoD based positioning, and multi-RTT positioning.

[0325] The receive beam information may be, for example, an RS resource indicator.

[0326] The RS resource indicator may be, for example, at least one of an RS resource ID, an RS resource set ID, and an SRS resource indicator (eg, srs-ResourceIndicator).

[0327] The indicator of the RS resource may be information of an SRS resource / resource set that uses the same spatial domain transmit filter / transmit beam as the spatial domain receive filter / receive beam used for the corresponding measurement.

[0328] The UE may be configured with an SRS resource set for reporting received beam information, where, for example, the usage of the SRS resource set may be set to at least one of receive beam determination and L1-RSRP with received beam information.

[0329] The UE / NW may expect / assume / determine that if the same SRS resource ID / SRS resource set ID is indicated, it is the same UE Rx TEG.

[0330] <<Variation of the third embodiment>> When spatial domain beam prediction is performed in a network, the number of candidate beams measured by the network (first number) and the number of candidate beams including beams to be notified to a UE (second number) may be determined separately (variation 1).

[0331] For example, the first number and the second number may be different. For example, the first number may be less than the second number.

[0332] The UE may assume that the number of transmitting beams of the UE is different from the number of receiving beams that the NW requests it to measure.

[0333] The UE may assume that the number of CRIs / SSBRIs / RS resource indicators / beam indices to report will be different (or configured differently) based on the beam prediction of the network.

[0334] Furthermore, when specific upper layer parameters are set, the receive panel (UE capability index / UE capability value set) / receive beam (receive spatial domain filter) may (always) be equal for each measurement / measurement result included in one report (e.g., UCI / CSI report / beam measurement report) (Variation 2).

[0335] The UE may (always) determine / assume that the receive panel (UE capability index / UE capability value set) / receive beam (receive spatial domain filter) is equal for each measurement / measurement result included in one report (e.g., UCI / CSI report / beam measurement report).

[0336] In addition, variation 2 may be applicable to both the case where the UE reports information (beam information) regarding the receiving beam and the case where the UE reports beam information.

[0337] According to the above third embodiment, beam information can be appropriately transmitted from the UE to the NW.

[0384] (Wireless Communication System) The configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination thereof.

[0385] 15 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 (which may be simply referred to as system 1) may be a system that realizes communication using Long Term Evolution (LTE) or 5th generation mobile communication system New Radio (5G NR) specified by the Third Generation Partnership Project (3GPP).

[0386] The wireless communication system 1 may also support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), etc.

[0387] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (Master Node (MN)), and the NR base station (gNB) is the secondary node (Secondary Node (SN)). In NE-DC, the NR base station (gNB) is the MN, and the LTE (E-UTRA) base station (eNB) is the SN.

[0388] The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity in which both the MN and SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0389] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The locations and numbers of the cells and user terminals 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as base station 10.

[0390] The user terminal 20 may be connected to at least one of the multiple base stations 10. The user terminal 20 may utilize at least one of carrier aggregation (CA) using multiple component carriers (CCs) and dual connectivity (DC).

[0391] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may correspond to a higher frequency band than FR2.

[0392] 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.

[0393] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

[0462] For example, a base station, a user terminal, etc. according to an embodiment of the present disclosure may function as a computer that performs processing of the wireless communication method of the present disclosure. Fig. 18 is a diagram illustrating an example of the hardware configuration of a base station and a user terminal according to an embodiment. The above-described base station 10 and user terminal 20 may be physically 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, etc.

[0463] In the present disclosure, the terms apparatus, circuit, device, section, unit, etc. may be used interchangeably. The hardware configurations of the base station 10 and the user terminal 20 may be configured to include one or more of the devices shown in the drawings, or may be configured to exclude some of the devices.

[0464] For example, although only one processor 1001 is shown, there may be multiple processors. Furthermore, processing may be performed by one processor, or processing may be performed by two or more processors simultaneously, serially, or in other ways. Furthermore, processor 1001 may be implemented by one or more chips.

[0465] Each function in the base station 10 and the user terminal 20 is realized, for example, by loading specified software (programs) onto hardware such as a processor 1001 and a memory 1002, causing the processor 1001 to perform calculations, control communication via the communication device 1004, and control at least one of reading and writing data in the memory 1002 and the storage 1003.

[0466] The processor 1001, for example, runs an operating system to control the entire computer. The processor 1001 may be configured as a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic unit, a register, etc. For example, at least a part of the above-mentioned control unit 110 (210), transceiver unit 120 (220), etc. may be realized by the processor 1001.

The programs used are those that cause a computer to execute at least some of the operations described in the above-described embodiments. For example, the control unit 110 (210) may be implemented by a control program stored in the memory 1002 and running on the processor 1001, and the other functional blocks may be implemented in a similar manner.

[0468] The memory 1002 is a computer-readable recording medium and may be configured by at least one of, for example, Read Only Memory (ROM), Erasable Programmable ROM (EPROM), Electrically EEPROM (EEPROM), Random Access Memory (RAM), or other suitable storage medium. The memory 1002 may also be referred to as a register, cache, main memory, etc. The memory 1002 may store executable programs (program codes), software modules, etc. for implementing a wireless communication method according to an embodiment of the present disclosure.

[0469] Storage 1003 is a computer-readable recording medium and may be composed of at least one of, for example, a flexible disk, a floppy disk, a magneto-optical disk (e.g., a compact disc (e.g., a Compact Disc ROM (CD-ROM)), a digital versatile disc, a Blu-ray disc), a removable disk, a hard disk drive, a smart card, a flash memory device (e.g., a card, a stick, a key drive), a magnetic stripe, a database, a server, or other suitable storage medium. Storage 1003 may also be referred to as an auxiliary storage device.

[0470] The communication device 1004 is hardware (transmission / reception device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as, for example, a network device, a network controller, a network card, or a communication module. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. to realize at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the above-mentioned transmission / reception unit 120 (220), transmission / reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission / reception unit 120 (220) may be implemented as a transmission unit 120a (220a) and a reception unit 120b (220b) that are physically or logically separated.

[0471] The input device 1005 is an input device (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that accepts input from the outside. The output device 1006 is an output device (e.g., a display, a speaker, a light emitting diode (LED) lamp, etc.) that outputs to the outside. Note that the input device 1005 and the output device 1006 may be integrated into one device (e.g., a touch panel).

[0472] Furthermore, each device, such as the processor 1001 and the memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

[0473] Furthermore, the base station 10 and the user terminal 20 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), or a field programmable gate array (FPGA), and some or all of the functional blocks may be realized using this hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0474] (Modifications) Note that terms described in the present disclosure and terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may be interchangeable. A signal may also be a message. A reference signal may be abbreviated as RS, and may also be called a pilot, pilot signal, etc. depending on the applicable standard. A component carrier (CC) may also be called a cell, frequency carrier, carrier frequency, etc.

[0475] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0476] Here, the numerology may be a communication parameter applied to at least one of transmission and reception of a signal or channel, and may indicate at least one of, for example, Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, Transmission Time Interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by a transceiver in the frequency domain, and specific windowing performed by a transceiver in the time domain.

[0477] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may also be a time unit based on numerology.

[0478] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0479] A radio frame, a subframe, a slot, a minislot, and a symbol all represent time units for transmitting signals. The radio frame, the subframe, the slot, the minislot, and the symbol may be referred to by other names corresponding to the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be interchangeable.

[0480] For example, one subframe may be referred to as a TTI, or multiple consecutive subframes may be referred to as a TTI, or one slot or one minislot may be referred to as a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0481] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.
