Description

Terminal and Communication Method

[0001] The present invention relates to a terminal and a communication method in a wireless communication system.

[0002] In 3GPP (Registered Trademark) (3rd Generation Partnership Project), it evolves towards the 6th generation mobile communication system (6G), and Network Energy Saving (NES) becomes an important requirement in its design. NES aims to reduce the overall energy consumption of the network, and various technologies are being studied to achieve this. For example, in cells operating in high-frequency bands, it has been proposed to introduce SSB-less cells that stop transmitting SSB (Synchronization Signal Block) or extend the transmission period of SSB. By such an approach, it is possible to reduce the power consumption of the base station and improve the operation efficiency of the network.

[0003] On the other hand, when realizing NES, it may affect the radio resource management (RRM) measurements performed by the user equipment (UE). In particular, extending the SSB transmission period or introducing SSB-less cells changes the pattern and timing of the signals to be measured by the UE. In such a situation, a mechanism for the network to provide appropriate measurement resources and settings to the UE is required.

[0004] 3GPP TS 38.300 V18.2.0(2024-06)3GPP TS 38.401 V18.2.0(2024-06)

[0005] However, in 6G networks, extending the SSB transmission cycle or introducing SSB-less cells to implement NES changes the SSB pattern measured by the UE, but it is unclear how the network should configure the SSB pattern for NES measurement for the UE. Furthermore, when applying NES, it is expected that not only SSB but also CSI-RS (Channel State Information Reference Signal) will be measured, but the method for configuring measurement resources for CSI-RS is not currently specified. In addition, it is required that the UE secures appropriate measurement resources when performing measurements during idle mode or in the initial stages of network connection, but the method for doing so is not clearly defined. Therefore, in wireless communication systems that support NES, there is a risk that the UE may not be able to perform NES measurements.

[0006] The terminal in this embodiment includes a receiving unit that receives information from a base station specifying a resource pattern for the network energy saving function to be measured, and a control unit that performs measurement of the resource based on the specified pattern.

[0007] According to this embodiment, a terminal in a wireless communication system can appropriately measure resources corresponding to the network energy saving function.

[0009] This embodiment will be described below with reference to the drawings. Note that the embodiments described below are examples, and the embodiments to which the present invention applies are not limited to those described below.

[0010] The wireless communication system of this embodiment operates using existing technology. Existing technology is, for example, wireless communication technology based on communication standards such as the 3GPP standard. Existing technology is, for example, NR (New Radio), but is not limited to existing NR. As used herein, the term "NR" has a broad meaning that includes NR (5G) and later systems (e.g., 6G), unless otherwise specified.

[0011] In the embodiments described below, we will use terms such as SS (Synchronization signal), PSS (Primary SS), SSS (Secondary SS), PBCH (Physical broadcast channel), PRACH (Physical random access channel), PDCCH (Physical Downlink Control Channel), PDSCH (Physical Downlink Shared Channel), PUCCH (Physical Uplink Control Channel), and PUSCH (Physical Uplink Shared Channel), which are used in existing LTE systems. This is for convenience of description, and similar signals, functions, etc., may be called by other names. In NR, the above terms will be referred to as SS, PSS, SSS, PBCH, PRACH, etc., without any particular distinction from LTE.

[0012] In this embodiment, the duplex method may be a TDD (Time Division Duplex) method, an FDD (Frequency Division Duplex) method, or any other method (for example, a Flexible Duplex).

[0013] In this embodiment, "configuring" wireless parameters means that predetermined values ​​are pre-configured, or that wireless parameters notified by the base station 10 or terminal 20 are configured.

[0014] Figure 1 shows an example of the configuration of a wireless communication system in this embodiment. The wireless communication system in this embodiment includes a base station 10 and a terminal 20, as shown in Figure 1. Although Figure 1 shows one base station 10 and one terminal 20, this is an example, and there may be multiple base stations 10 and terminal 20.

[0015] Base station 10 is a communication device that provides one or more cells and communicates wirelessly with terminal 20. The physical resources of the wireless signal are defined in the time domain and the frequency domain. The time domain may be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols, and the frequency domain may be defined by the number of subcarriers or resource blocks. Base station 10 transmits synchronization signals and system information to terminal 20. Synchronization signals are, for example, PSS and SSS. System information is transmitted, for example, via PBCH and is also called broadcast information. Synchronization signals and system information may also be called SSB (SS / PBCH block). As shown in Figure 1, base station 10 transmits control signals or data to terminal 20 via DL (Downlink) and receives control signals or data from terminal 20 via UL (Uplink). Both base station 10 and terminal 20 are capable of transmitting and receiving signals using beamforming. Furthermore, both base station 10 and terminal 20 are capable of applying MIMO (Multiple Input Multiple Output) communication to DL or UL. Furthermore, both the base station 10 and the terminal 20 may communicate via secondary cells (SCell) and primary cells (PCell) using Carrier Aggregation (CA). In addition, the terminal 20 may communicate via the primary cell of base station 10 and the primary secondary cell group cell (PSCell) of another base station 10 using Dual Connectivity (DC).

[0016] Base station 10 may also be referred to as a RAN (Radio Access Network) node. Base station 10 is, for example, a gNodeB (gNB) in NR.

[0017] Terminal 20 is a communication device equipped with wireless communication capabilities, such as a UE (User Equipment), smartphone, mobile phone, tablet, wearable device, or M2M (Machine-to-Machine) communication module. As shown in Figure 1, Terminal 20 receives control signals or data from the base station 10 via DL and transmits control signals or data to the base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. Terminal 20 also receives various reference signals transmitted from the base station 10 and performs propagation path quality measurements based on the reception results of these reference signals.

[0018] In the following explanation, " / " means "and / or" unless otherwise specified, or unless the context makes it clear that it has a different meaning.

[0019] The following describes examples of this embodiment. Each example may be performed independently, or any combination of multiple examples may be performed.

[0020] According to this embodiment, new information is defined to specify the SSB (Synchronization Signal Block) / CSI-RS (Channel State Information Reference Signal) to be measured for NES, which is used in measurements by terminal 20. The names of the parameters and information elements in the following description are examples and may be any names.

[0021] In this embodiment, SSB is an example of a synchronization signal or a block containing a synchronization signal. CSI-RS is an example of a reference signal used to measure the state of the wireless communication channel between terminal 20 and base station 10.

[0022] In this embodiment, the SSB and CSI-RS, which are the targets of measurement, are examples of resources to be measured. Resources may also be referred to as wireless resources or signals.

[0023] (Example 1) measObject is an Information Element (IE) for defining information related to the cell and frequency to be measured, and indicates the criteria for terminal 20 to perform the measurement. measObject includes the frequency to be measured, the specification of the signal type, the measurement conditions, frequency hopping information, and the reference signal settings. measObject is associated with SSB and CSI-RS pattern information via referenceSignalConfig, which indicates the setting information of the reference signals (SSB and CSI-RS) to be measured. The SSB pattern information is SSBToMeasure, which specifies the SSB pattern to be measured. The CSI-RS pattern information is CSI-RSToMeasure, which specifies the CSI-RS pattern to be measured.

[0024] According to Example 1, a new IE may be provided that specifies the SSB to be measured for NES and / or a new IE that specifies the CSI-RS to be measured for NES, which are referenced by measObject.

[0025] As shown in Figure 2, in step S101, the base station 10 transmits a new IE specifying the measObject and the SSB to be measured for NES, and / or a new IE specifying the CSI-RS to be measured for NES, to the terminal 20.

[0026] New IEs specifying the SSB / CSI-RS to be measured for measObject and NES are sent, for example, using RRC messages (e.g., RRCReconfiguration, RRCSetup, or RRCConnectionReestablishment messages). The RRCReconfiguration message is used to set or reset operating parameters, including the measurement settings of terminal 20. The RRCSetup message is used to establish the initial RRC connection. The RRCConnectionReestablishment message is used to re-establish the RRC connection. New IEs specifying the SSB / CSI-RS to be measured for measObject and NES may be included in the same RRC message or sent as separate RRC messages.

[0027] A new IE specifying the SSB to be measured for NES is information indicating the SSB pattern to be measured for NES, for example, SSBToMeasure for NES (NES-SSB-ToMeasure). As another example, a new IE specifying the SSB to be measured for NES may be an SMTC (SSB Measurement Timing Configuration) for NES (NES-SMTC). NES-SMTC includes a PCI (Physical Cell ID List) list and a periodicity. The period included in NES-SMTC may be longer than the period of a normal SMTC. In this embodiment, NES-SSB-ToMeasure may be interpreted as NES-SMTC.

[0028] A new IE specifying the CSI-RS to be measured for NES is information indicating the CSI-RS pattern to be measured for NES, for example, CSI-RSToMeasure for NES (NES-CSI-RS-ToMeasure). As another example, a new IE specifying the CSI-RS to be measured for NES may be CSI-RS MTC (Measurement Timing Config) for NES (NES-CSI-RS MTC). NES-CSI-RS MTC includes a PCI list and a period. The period included in NES-CSI-RS MTC may be longer than the period of a normal CSI-RS MTC. In this embodiment, NES-CSI-RS-ToMeasure may be interpreted as NES-CSI-RS MTC.

[0029] The new IE that specifies the SSB / CSI-RS to be measured for NES is also called information that specifies the resource pattern for the NES function being measured.

[0030] SSBToMeasure for NES and CSI-RSToMeasure for NES may be included in the parameter referenceSignalConfig. SSBToMeasure for NES may also be included in SSB-MTC (SSB Measurement Timing Configuration).

[0031] In step S102, terminal 20, based on the received measObject, refers to a new IE specifying the SSB to be measured for NES and / or a new IE specifying the CSI-RS to be measured for NES, and performs the measurement.

[0032] Terminal 20 identifies the frequency to be measured, the type of signal (SSB or CSI-RS), and the measurement conditions from the received measObject. The measObject is associated with referenceSignalConfig. referenceSignalConfig is directly or indirectly associated with SSBToMeasure for NES or CSI-RSToMeasure for NES. Based on the measObject, Terminal 20 references SSBToMeasure for NES or CSI-RSToMeasure for NES via referenceSignalConfig and performs the measurement on the SSB or CSI-RS to be measured as indicated by SSBToMeasure for NES.

[0033] Figures 3A-3C show an example of the configuration of measObject and referenceSignalConfig in Example 1. As shown in Figure 3C, NES-SSB-ToMeasure is associated with ReferenceSignalConfig. Figure 4 shows an example of the configuration of SSB-MTC in Example 1. As shown in Figure 4, NES-SSB-ToMeasure is associated with SSB-MTC3-r16.

[0034] According to the above-described embodiment 1, even if the NES implements measures such as extending the SSB transmission cycle or introducing SSB-less cells, the terminal 20 can be provided with information indicating the newly defined resource patterns (e.g., SSB and CSI-RS) corresponding to the NES being measured. This allows the terminal 20 to appropriately perform resource measurements using this information.

[0035] (Example 2) measIdleConfig is a parameter that provides settings for terminal 20 to perform measurements while in idle mode. measIdleConfig includes information elements such as idleMeasFreqList, idleMeasCycle, measurement conditions, and measurement timing. idleMeasFreqList is a list of frequencies to be measured, specifying the carrier frequencies that terminal 20 should measure. This frequency list includes both same and different frequency bands. idleMeasCycle indicates the periodicity (cycle) of the measurement, specifying how often terminal 20 should perform the measurement. The measurement conditions are, for example, thresholds for signal strength or quality of the signal to be measured. The measurement timing is a slot or frame offset.

[0036] According to Example 2, a new IE may be defined that specifies the SSB to be measured for the NES and / or a new IE that specifies the CSI-RS to be measured for the NES, which are associated with measIdleConfig.

[0037] In step S201 of Figure 5, the base station 10 sends, for example, a new IE specifying measIdleConfig and the SSB to be measured for the NES, and / or a new IE specifying the CSI-RS to be measured for the NES, to the terminal 20 via an RRC message. The RRC message is, for example, an RRCSetup message or an RRCConnectionReestablishment message.

[0038] SSBToMeasure for NES may be included in the parameter ssb-MeasConfig. SSBToMeasure for NES and CSI-RSToMeasure for NES may be included in the parameter referenceSignalConfig.

[0039] In step S202, terminal 20, based on the received measIdleConfig, refers to a new IE specifying the SSB to be measured for the NES and / or a new IE specifying the CSI-RS to be measured for the NES, and performs the measurement.

[0040] FIG. 6 is a diagram showing an example of the configurations of measIdleConfig and ssb-MeasConfig in Embodiment 2. In the example of FIG. 6, ssb-MeasConfig includes NES-SSB-ToMeasure.

[0041] According to Embodiment 2 described above, even when the terminal 20 performs measurements during the RRC idle mode, information indicating the pattern of resources (e.g., SSB and CSI-RS) corresponding to the NES to be measured can be provided to the terminal 20. Thereby, the terminal 20 can appropriately execute resource measurements using this information.

[0042] (Embodiment 3) According to Embodiment 3, a new IE specifying the SSB to be measured for NES included in or associated with the notification information (e.g., SIB2 or SIB4) and / or a new IE specifying the CSI-RS to be measured for NES may be defined.

[0043] In step S301 of FIG. 7, the base station 10 transmits notification information (e.g., SIB2 or SIB4) including a new IE specifying the SSB to be measured for NES and / or a new IE specifying the CSI-RS to be measured for NES. In step S302, the terminal 20 refers to the new IE specifying the SSB to be measured for NES and / or the new IE specifying the CSI-RS to be measured for NES and executes measurements.

[0044] FIGS. 8A and 8B are diagrams showing an example of the configuration of SIB2 in Embodiment 3. As shown in FIG. 8B, SIB2 includes NES-SSB-ToMeasure. FIGS. 9A and 9B are diagrams showing an example of the configuration of SIB4 in Embodiment 3. As shown in FIG. 9B, SIB4 includes NES-SSB-ToMeasure.

[0045] According to Embodiment 3 described above, even at the initial stage of network connection, information indicating the pattern of resources (e.g., SSB and CSI-RS) corresponding to the NES to be measured can be provided to the terminal 20. Thereby, the terminal 20 can appropriately execute resource measurements using this information.

[0046] (Configuration Example of a New IE for Designating the SSB to Be Measured for NES) Figure 10 is a diagram showing an example of the conventional Short bitmap configuration of SSB-ToMeasure. As shown in Figure 10, the Short bitmap configuration has 4 bits per half frame. Bit "1" indicates that the SSB is transmitted at the corresponding bit position. Bit "0" indicates that the SSB is not transmitted at the corresponding bit position. Thus, in the Short bitmap configuration, a maximum of 4 SSBs can be transmitted (measured) per half frame.

[0047] In the present embodiment, the SSB-ToMeasure for NES may be shown as a Short bitmap configuration, as shown in Figure 11. For example, in the SSB-ToMeasure for NES, the number of SSBs that can be transmitted (measured) per half frame may be restricted. In the example of Figure 11, it may be restricted such that only 1 bit out of 4 bits per half frame is used for transmitting the SSB. Note that in the Short bitmap configuration of the SSB-ToMeasure for NES, the position and number of bits at which the SSB is transmitted may be arbitrary. That is, the number of bits indicating the transmission of CSI-RS among the bits included in the SSB-ToMeasure for NES may be restricted to a predetermined number or less.

[0048] The SSB-ToMeasure for NES in the present embodiment may be shown as a Medium bitmap configuration or a Long bitmap configuration. The Medium bitmap configuration has 8 bits per half frame and can indicate the transmission (measurement) feasibility of a maximum of 8 SSBs. The Long bitmap configuration has 64 bits per half frame and can indicate the transmission (measurement) feasibility of a maximum of 64 SSBs.

[0049] The SSB-ToMeasure for NES may be shown as an NES-specific bitmap configuration or a very short bitmap configuration, as shown in Figures 12A and 12B. The very short bitmap configuration of the SSB-ToMeasure for NES may be a configuration of 1 bit per half frame, as shown in Figure 12A, or a configuration of 2 bits per half frame, as shown in Figure 12B. In other words, the very short bitmap configuration of the SSB-ToMeasure for NES may indicate that it is possible to transmit (measure) a maximum of 1 or 2 SSBs per half frame.

[0050] The NES-specific Short bitmap configuration and Very Short bitmap configuration are bitmap configurations with 4 bits or less per Half frame.

[0051] (Example of a new IE configuration for specifying the CSI-RS to be measured for NES) The configuration of CSI-RS-ToMeasure for NES may be the same as the configuration of SSB-ToMeasure for NES described above. In this embodiment, CSI-RS-ToMeasure for NES may be shown as a Short bitmap configuration, as shown in Figure 13. For example, in CSI-RS-ToMeasure for NES, the number of SSBs that can be transmitted (measured) per Half frame may be limited. In the example in Figure 13, it may be limited so that only one bit out of four bits per Half frame is used for transmitting the SSB. In the Short bitmap configuration of CSI-RS-ToMeasure for NES, the position and number of bits to which the SSB is transmitted may be arbitrary. That is, the number of bits that indicate that a CSI-RS is being transmitted among the bits included in CSI-RS-ToMeasure for NES may be limited to a predetermined number or less.

[0052] The CSI-RS-ToMeasure for NES in this embodiment may be shown as a Medium bitmap configuration or a Long bitmap configuration. The Medium bitmap configuration has 8 bits per Half frame and can indicate whether up to 8 SSBs can be transmitted (measured). The Long bitmap configuration has 64 bits per Half frame and can indicate whether up to 64 SSBs can be transmitted (measured).

[0053] The CSI-RS-ToMeasure for NES may be shown as an NES-specific bitmap configuration or a very short bitmap configuration, as shown in Figures 14A and 14B. The very short bitmap configuration of the CSI-RS-ToMeasure for NES may be a configuration of 1 bit per half frame, as shown in Figure 12A, or a configuration of 2 bits per half frame, as shown in Figure 12B. In other words, the very short bitmap configuration of the CSI-RS-ToMeasure for NES may indicate that it is possible to transmit (measure) a maximum of 1 or 2 SSBs per half frame.

[0054] (Device Configuration) Next, an example of the functional configuration of the base station 10 and terminal 20 that perform the processes and operations described above will be explained.

For example, the receiving unit 220 receives the low-power wake-up signal from the base station 10.

[0061] As described in the embodiment, the control unit 240 performs control related to setting, instructing, and notifying of low-power wake-up signals. The signal transmission function unit of the control unit 240 may be included in the transmission unit 210, and the signal reception function unit of the control unit 240 may be included in the reception unit 220.

[0062] (Hardware Configuration) The block diagrams (Figures 15 and 16) used in the description of the above embodiments show functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized using one device that is physically or logically coupled, or it may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wired or wireless connections). A functional block may be realized by combining the above one device or the above multiple devices with software.

In all cases, as mentioned above, the method of implementation is not particularly limited.

[0064] For example, the base station 10, terminal 20, etc. in one embodiment of the present disclosure may function as a computer that processes the wireless communication method of the present disclosure. Figure 17 is a diagram showing an example of the hardware configuration of the base station 10 and terminal 20 according to one embodiment of the present disclosure.

[0066] Each function in the base station 10 and terminal 20 is realized by loading predetermined software (programs) onto hardware such as the processor 1001 and storage device 1002, which allows the processor 1001 to perform calculations, control communication by the communication device 1004, and control at least one of the reading and writing of data in the storage device 1002 and auxiliary storage device 1003.

The program used is one that causes the computer to execute at least a part of the operations described in the above embodiment. For example, the control unit 140 of the base station 10 shown in Figure 15 may be implemented by a control program stored in the storage device 1002 and operated by the processor 1001. Also, for example, the control unit 240 of the terminal 20 shown in Figure 16 may be implemented by a control program stored in the storage device 1002 and operated by the processor 1001. Although the above-described processes have been explained as being executed by one processor 1001, they may be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. The program may also be transmitted from the network via a telecommunications line.

[0092] (Supplement to Embodiments) Although these embodiments have been described above, the disclosed invention is not limited to these embodiments, and those skilled in the art will understand various modifications, alterations, alternatives, substitutions, etc. Specific numerical examples have been used to facilitate understanding of the invention, but unless otherwise specified, these numerical values ​​are merely examples, and any appropriate values ​​may be used. The division of items in the above description is not essential to the present invention, and matters described in two or more items may be combined as needed, and matters described in one item may be applied to matters described in another item (as long as they do not contradict each other). The boundaries of functional units or processing units in the functional block diagram do not necessarily correspond to the boundaries of physical parts. The operation of multiple functional units may be physically performed by one part, or the operation of one functional unit may be physically performed by multiple parts. The processing procedures described in the embodiments may be rearranged as long as they do not contradict each other. For the convenience of explaining the processing, the base station 10 and terminal 20 have been described using functional block diagrams, but such devices may be realized in hardware, software, or a combination thereof. The software operated by the processor of the base station 10 according to this embodiment and the software operated by the processor of the terminal 20 according to this embodiment may be stored in any suitable storage medium such as random access memory (RAM), flash memory, read-only memory (ROM), EPROM, EEPROM, register, hard disk (HDD), removable disk, CD-ROM, database, server, or other appropriate storage medium.

[0095] The processing procedures, sequences, flowcharts, etc., of each aspect / embodiment described herein may be reordered, provided they are consistent with each other. For example, the methods described herein present various step elements in an exemplary order and are not limited to that specific order.

[0096] In this specification, specific operations performed by the base station 10 may, in some cases, be performed by its upper node. In a network consisting of one or more network nodes having a base station 10, it is clear that various operations performed for communication with the terminal 20 can be performed by the base station 10 and at least one of the other network nodes (for example, an MME or S-GW, but not limited to these). Although the above example illustrates the case where there is one other network node besides the base station 10, the other network node may be a combination of multiple other network nodes (for example, an MME and an S-GW).

[0097] The information or signals described in this disclosure may be output from a higher layer (or lower layer) to a lower layer (or higher layer). They may also be input and output via multiple network nodes.

[0098] Input and output information may be stored in a specific location (e.g., memory) or managed using a management table. Input and output information may be overwritten, updated, or appended to. Output information may be deleted. Input information may be transmitted to other devices.

[0099] The determination in this disclosure may be made by a value represented by one bit (0 or 1), by a Boolean value (true or false), or by a numerical comparison (for example, a comparison with a predetermined value).

[0100] Software should be broadly interpreted to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, and so on, whether they are called software, firmware, middleware, microcode, hardware description languages, or by any other name.

[0101] Furthermore, software, instructions, information, etc., may be transmitted and received via a transmission medium. For example, if software is transmitted from a website, server, or other remote source using at least one of wired technology (such as coaxial cable, fiber optic cable, twisted pair, or digital subscriber line (DSL)) and wireless technology (such as infrared or microwave), then at least one of these wired and wireless technologies is included in the definition of a transmission medium.

[0102] The information, signals, etc. described in this disclosure may be represented using any of the various different techniques. For example, the data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0103] In addition, terms used in this disclosure and terms necessary for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, at least one of the channel and symbol may be a signal (signaling). Also, a signal may be a message. Furthermore, a component carrier (CC) may be called a carrier frequency, cell, frequency carrier, etc.

[0104] The terms “system” and “network” as used in this disclosure are interchangeable.

[0105] Furthermore, the information, parameters, etc., described in this disclosure may be expressed using absolute values, relative values ​​from a given value, or other corresponding information. For example, wireless resources may be indicated by an index.

[0106] The names used for the parameters described above are not restrictive in any way. Furthermore, the formulas and other expressions using these parameters may differ from those expressly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, and therefore, the various names assigned to these various channels and information elements are not restrictive in any way.

[0107] In this disclosure, terms such as "Base Station (BS)", "wireless base station", "base station equipment", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", and "component carrier" may be used interchangeably. Base stations may also be referred to by terms such as macrocell, small cell, femtocell, and picocell.

[0108] A base station can accommodate one or more (e.g., three) cells. If a base station accommodates multiple cells, the entire coverage area of ​​the base station can be divided into multiple smaller areas, each of which may also be provided with communication services by a base station subsystem (e.g., a Remote Radio Head (RRH)). The terms “cell” or “sector” refer to part or all of the coverage area of ​​at least one of the base station and / or base station subsystems that provide communication services in that coverage.

[0109] In this disclosure, the transmission of information by a base station to a terminal may be interpreted as the base station instructing the terminal to perform control or operation based on the information.

[0110] In this disclosure, terms such as "Mobile Station (MS)", "user terminal", "User Equipment (UE)", and "terminal" may be used interchangeably.

[0111] A mobile station may also be referred to by those skilled in the art as a 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 several other appropriate terms.

[0112] At least one of the base station and the mobile station may be called a transmitting device, a receiving device, a communication device, etc. 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 refers to a movable object, and its speed of movement is arbitrary. This also includes the case when the mobile body is stationary. The mobile body includes, but is not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, handcarts, rickshaws, ships and other watercraft, airplanes, rockets, satellites, drones (registered trademark), multicopters, quadcopters, balloons, and items mounted on them. The mobile body may also be a mobile body that moves autonomously based on operation commands. It may be a vehicle (e.g., a car, an airplane, etc.), an unmanned mobile body (e.g., a drone, an autonomous vehicle, etc.), or a robot (manned or unmanned). Furthermore, at least one of the base station and the mobile station may include devices that do 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.

[0113] Furthermore, the term "base station" in this disclosure may be interpreted as "user terminal." For example, the various aspects / embodiments of this disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between multiple terminals 20 (which may be called, for example, D2D (Device-to-Device), V2X (Vehicle-to-Everything)). In this case, the terminals 20 may have the functions that the base station 10 has. Also, terms such as "uplink" and "downlink" may be interpreted as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, uplink channel, downlink channel, etc., may be interpreted as side channel.

[0114] Similarly, the term "user terminal" in this disclosure may be replaced with "base station." In this case, the base station may be configured to have the same functions as the user terminal described above.

[0115] As used in this disclosure, the terms “determining” and “determining” may encompass a wide variety of actions. “Determining” may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, or inquiring (e.g., searching in a table, database, or other data structure), or ascertaining. “Determining” may also include receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, or accessing (e.g., accessing data in memory). Furthermore, "judgment" and "decision" can include considering something as having been "judged" or "decided" after resolving, selecting, choosing, establishing, comparing, etc. In other words, "judgment" and "decision" can include considering something as having been "judged" or "decided" after some action. Also, "judgment (decision)" can be reinterpreted as "assuming," "expecting," or "considering."

[0116] The terms “connected,” “coupled,” and any variations thereof mean any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are “connected” or “coupled” with each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, “connection” may be reinterpreted as “access.” As used in this disclosure, two elements may be considered to be “connected” or “coupled” with each other using at least one of one or more wires, cables, and printed electrical connections, and, in some non-limiting and non-exclusive examples, electromagnetic energy having wavelengths in the radio frequency domain, microwave domain, and optical (both visible and invisible) domain.

[0117] The reference signal can also be abbreviated as RS (Reference Signal), and may be called a pilot depending on the applicable standard.

[0118] In this disclosure, the phrase "based on" does not mean "based solely on" unless otherwise specified. In other words, the phrase "based on" means both "based solely on" and "based at least on."

[0119] Any reference to elements using the designations “first,” “second,” etc., as used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient way to distinguish between two or more elements. Accordingly, references to the first and second elements do not imply that only two elements may be employed, or that the first element must precede the second element in any way.

[0120] In the configuration of each of the above devices, "means" may be replaced with "part," "circuit," "device," etc.

[0121] Where the terms “include,” “including,” and variations thereof are used in this disclosure, these terms are intended to be inclusive, as is the term “comprising.” Furthermore, the term “or” as used in this disclosure is not intended to mean exclusive OR.

[0122] A wireless frame may consist of one or more frames in the time domain. Each of these frames in the time domain may be called a subframe. A subframe may further consist 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.

[0123] Numerical logic may be communication parameters applied to at least one of the transmission and reception of a signal or channel. Numerical logic may include, for example, at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, specific filtering processes performed by the transceiver in the frequency domain, and specific windowing processes performed by the transceiver in the time domain.

[0124] A slot may consist of one or more symbols in the time domain (such as OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A slot may also be a time unit based on neurologic.

[0125] A slot may include multiple minislots. Each minislot may consist of one or more symbols in the time domain. Minislots may also be called subslots. Minislots may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called a PDSCH (or PUSCH) mapping type B.

[0126] Wireless frames, subframes, slots, minislots, and symbols all represent units of time when transmitting a signal. Different names may be used for each of these terms.

[0127] For example, one subframe may be called a Transmission Time Interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. In other words, at least one of a subframe and a TTI may be a subframe in existing LTE (1 ms), a period shorter than 1 ms (e.g., 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.

[0128] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, the base station schedules each terminal 20 to allocate wireless resources (such as the frequency bandwidth and transmission power available to each terminal 20) in TTI units. However, the definition of TTI is not limited to this.

[0129] TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, code words, etc., or it may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the actual time interval (e.g., number of symbols) in which the transport block, code block, code word, etc. are mapped may be shorter than the TTI.

[0130] Furthermore, if one slot or one mini-slot is referred to as a TTI, then one or more TTIs (i.e., one or more slots or one or more mini-slots) may constitute the minimum time unit for scheduling. In addition, the number of slots (number of mini-slots) that constitute this minimum time unit for scheduling may be controlled.

[0131] A TTI with a time length of 1 ms may be called a normal TTI, a long TTI, a normal subframe, a long subframe, a slot, etc. A TTI shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini slot, a sub slot, a slot, etc.

[0132] Furthermore, long TTIs (e.g., normal TTIs, subframes, etc.) may be interpreted as TTIs with a time length exceeding 1 ms, and short TTIs (e.g., shortened TTIs, etc.) may be interpreted as TTIs with a TTI length less than that of a long TTI but 1 ms or more.

[0133] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and in the frequency domain, it may contain one or more consecutive subcarriers. The number of subcarriers in an RB may be the same regardless of the neurology, for example, 12. The number of subcarriers in an RB may be determined based on the neurology.

[0134] Furthermore, the time domain of the RB may contain one or more symbols and may be the length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc., may each consist of one or more resource blocks.

[0135] One or more RBs may also be called a Physical RB (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB pair, RB pair, etc.

[0136] Furthermore, a resource block may consist of one or more resource elements (REs). For example, one RE may be a radio resource area comprising one subcarrier and one symbol.

[0137] A Bandwidth Part (BWP), also known as a partial bandwidth, may represent a subset of consecutive common resource blocks (RBs) for a particular neurology in a given carrier. These common RBs may be identified by an index of the RBs relative to a common reference point of the carrier. The PRBs may be defined and numbered within a given BWP.

[0138] A BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be set within a single carrier for a UE.

[0139] At least one of the configured BWPs may be active, and the UE does not need to assume that it will transmit or receive a predetermined signal / channel outside of the active BWP. In this disclosure, terms such as "cell" and "carrier" may be read as "BWP".

[0140] The structures described above, such as wireless frames, subframes, slots, minislots, and symbols, are merely illustrative. For example, the number of subframes included in a wireless frame, the number of slots per subframe or wireless frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, and the number of symbols, symbol length, and cyclic prefix (CP) length within a TTI can be varied in various ways.

[0141] In this disclosure, if articles are added through translation, such as a, an, and the in English, this disclosure may include the fact that the noun following these articles is plural.

[0142] In this disclosure, the term "A and B are different" may mean "A and B are different from each other." The term may also mean "A and B are each different from C." Terms such as "separate" and "combine" may be interpreted similarly to "different."

[0143] Each aspect / embodiment described in this disclosure may be used individually, in combination, or switched between as needed during implementation. Furthermore, notification of specific information (e.g., notification that "X is") is not limited to explicit notification, but may also be implicit (e.g., by not providing such notification).

[0144] Although the present disclosure has been described in detail above, it will be clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in modified and altered forms without departing from the intent and scope of the present disclosure as defined by the claims. Therefore, the descriptions in the present disclosure are illustrative and not intended to be restrictive in any way.
