Description

Technical Field

[0001] This invention relates to terminals, base stations, and communication methods in wireless communication systems. Background Technology

[0002] Within the 3GPP (3rd Generation Partnership Project), research was conducted on a wireless communication method known as 5G or NR (New Radio) to further increase system capacity, improve data transmission speed, and reduce latency in the radio space. In 5G, various wireless technologies and network architectures were researched to meet the requirements of achieving throughput of over 10Gbps and radio latency of less than 1ms (e.g., Non-Patent Literature 1 and Non-Patent Literature 2).

[0003] In NR, LTE continues to support the use of wideband carrier aggregation (CA) to secure data resources. Carrier aggregation secures wideband data resources by bundling multiple component carriers (CCs).

[0024] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the embodiments described below are examples, and the application of the present invention is not limited to the embodiments described below.

[0025] In the operation of the wireless communication system according to embodiments of the present invention, existing technologies are appropriately used. These existing technologies include, for example, existing LTE, but are not limited to, existing LTE. Furthermore, unless otherwise stated, the term "LTE" as used in this specification has a broad meaning that includes LTE-Advanced and subsequent methods (e.g., NR).

[0026] Furthermore, in the embodiments of the present invention described below, the terms 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) used in existing LTE systems are used. These are for ease of description, and the same signals and functions may also be referred to by other names. Additionally, the above terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, NR-PRACH, etc. However, even signals used in NR are not necessarily explicitly written as "NR-".

[0027] In addition, in embodiments of the present invention, the duplex mode can be TDD (Time Division Duplex), FDD (Frequency Division Duplex), or other modes (e.g., Flexible Duplex).

[0028] Furthermore, in embodiments of the present invention, the "configure" wireless parameters can be pre-configured predetermined values, or wireless parameters notified from the base station 10 or the terminal 20.

[0029] Figure 1 This is a diagram illustrating a structural example of a wireless communication system according to an embodiment of the present invention. For example... Figure 1 As shown, the wireless communication system in this embodiment of the invention includes a base station 10 and a terminal 20. Figure 1 The diagram shows one base station 10 and one terminal 20, but this is just one example; there could be multiple terminals.

[0030] Base station 10 is a communication device that provides one or more cells and wirelessly communicates with terminal 20. The physical resources of the wireless signal are defined in the time and frequency domains. The time domain can be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols, and the frequency domain can be defined by the number of subcarriers or resource blocks. Base station 10 sends synchronization signals and system information to terminal 20. Synchronization signals are, for example, NR-PSS and NR-SSS. System information is transmitted, for example, via NR-PBCH, also known as broadcast information. Synchronization signals and system information can also be referred to as SSB (SS / PBCH block). Figure 1 As shown, base station 10 sends 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 beamforming for signal transmission and reception. Furthermore, both base station 10 and terminal 20 can apply MIMO (Multiple Input Multiple Output) based communication to DL or UL. Additionally, base station 10 and terminal 20 can also communicate via CA (Carrier Aggregation) based secondary cells (SCell) and primary cells (PCell). Moreover, terminal 20 can also communicate via DC (Dual Connectivity) based primary cells of base station 10 and primary SCG cells of other base stations 10.

[0031] Terminal 20 is a communication device with wireless communication capabilities, such as a smartphone, mobile phone, tablet computer, wearable terminal, or M2M (Machine-to-Machine) communication module. Figure 1As shown, terminal 20 receives control signals or data from base station 10 via DL and transmits control signals or data to base station 10 via UL, thereby utilizing various communication services provided by the wireless communication system. Additionally, terminal 20 receives various reference signals transmitted from base station 10 and performs propagation path quality measurements based on the reception results of these reference signals.

[0032] Furthermore, LTE and NR support wideband carrier aggregation to ensure data resources. Carrier aggregation ensures wideband data resources by bundling multiple component carriers. For example, by bundling multiple 20MHz bandwidths, a 100MHz bandwidth can be used.

[0033] In previous carrier aggregation functions, data resources needed to be scheduled separately for the multiple component carriers that were bundled, which resulted in a large overhead for resource allocation.

[0034] Therefore, a method for allocating resources using scheduling units with a granularity different from that of the component carrier, and a terminal for allocating resources using scheduling units with a granularity different from that of the component carrier, are described.

[0035] Frequency fragmentation is defined as a framework that performs scheduling or aggregation at a different granularity than component carriers. Furthermore, "component carrier" can refer to the set of frequency resources corresponding to the previous scheduling unit (i.e., the actual CC described later), or it can refer to the set of frequency resources in frequency fragmentation (i.e., the virtual CC described later).

[0036] In addition, in carrier aggregation, aggregation with a different granularity than component carriers is defined as discontinuous carrier aggregation.

[0037] In addition, in carrier aggregation (discontinuous carrier aggregation), scheduling with a different granularity than component carriers is defined as discontinuous scheduling.

[0038] The granularity mentioned above, which differs from that of component carriers, can be a virtual CC unit, a BWP (Bandwidth Part) unit, a PRB (Physical Resource Block) unit, or a PRB set unit. A virtual CC refers to a carrier set that bundles all or part of the frequency resources contained in each component carrier from multiple component carriers. For example, a virtual CC can be conceived as being composed of multiple BWPs.

[0039] Figure 2 The first figure shows an example of the structure of a virtual CC according to an embodiment of the present invention. Figure 2The virtual CC#i shown is a carrier set formed by bundling BWP#a and BWP#b contained in each component carrier in multiple component carriers (CC#0 and CC#1).

[0040] Alternatively, a virtual CC can be conceived as consisting of multiple PRBs or sets of PRBs.

[0041] Figure 3 The second figure shows an example of the structure of a virtual CC according to an embodiment of the present invention. Figure 3 The virtual CC#i shown is a carrier set that bundles multiple PRBs contained in each component carrier (CC#0 and CC#1). Furthermore, these multiple PRBs or PRB sets can also be contained in one or more BWPs.

[0042] Hereinafter, the CC before bundling will be referred to as the actual CC, and the CC after bundling will be referred to as the virtual CC or nominal CC. However, the names are not limited to these. Furthermore, an actual CC can be any unit of a frequency resource, or it may not be defined or set as a CC. A virtual CC can be defined and set as a CC.

[0043] In addition, virtual CCs can be used in the same way as traditional single CCs in areas such as channel mapping, scheduling, HARQ (Hybrid Automatic Repeat Request), and configuration.

[0044] Alternatively, the actual CC can be replaced with continuous frequency resources, and the virtual CC can be replaced with non-continuous frequency resources.

[0045] Terminal 20 can also send terminal capability information indicating the composition of the virtual CC to base station 10. This terminal capability information indicating the composition of the virtual CC could be, for example, information indicating that the virtual CC is composed of multiple BWPs, or information indicating that the virtual CC is composed of multiple PRBs.

[0046] Alternatively, the terminal capability information indicating the composition of a virtual CC can also be information indicating support for a virtual CC composed of multiple BWPs and a virtual CC composed of multiple PRBs.

[0047] Terminal 20 can also send terminal capability information indicating the composition of the virtual CC to base station 10. This terminal capability information indicating the composition of the virtual CC could be, for example, information indicating that the virtual CC is composed of multiple BWPs, or information indicating that the virtual CC is composed of multiple PRBs.

[0048] Alternatively, the terminal capability information indicating the composition of a virtual CC can also be information indicating support for a virtual CC composed of multiple BWPs and a virtual CC composed of multiple PRBs.

[0049] Alternatively, terminal 20 may also envision the index used to identify each virtual CC being set by base station 10 via RRC. Alternatively, terminal 20 may envision the index used to identify each virtual CC as the minimum value of the component carrier index (e.g., in...). Figure 2 or Figure 3 (i=0) or the maximum value (e.g. in) Figure 2 or Figure 3 (i=1).

[0050] Terminal 20 can also be conceived as notifying the scheduling unit in discontinuous scheduling through (i) a virtual CC index, (ii) an index of multiple component carriers + an index of multiple BWPs, (iii) an index of multiple component carriers + an index of multiple PRBs or a set of PRBs, (iv) an index of multiple component carriers + an index of multiple BWPs + an index of multiple PRBs or a set of PRBs, etc.

[0051] Alternatively, terminal 20 can also be conceived as a resource unit for carrier aggregation that is a virtual CC, BWP, PRB, or PRB set.

[0052] Based on the above actions, resource allocation can be achieved at a granularity different from that of component carrier scheduling.

[0053] (Example)

[0054] In this embodiment, the constraints of using discontinuous frequency resources in the frequency domain in wireless communication are explained.

[0055] When a virtual CC is constituted by one or more actual CCs, the one or more actual CCs are constrained to meet predetermined conditions (restrictions). Base station 10 and terminal 20 assume these predetermined conditions (restrictions) and constitute a virtual CC.

[0056] The information involved in the predetermined conditions (constraints) can also be defined in the specification.

[0057] Alternatively, base station 10 may also notify terminal 20 of the information related to the constraint as a common signal.

[0058] Alternatively, terminal 20 may report the information related to the constraint to base station 10 as a UE capability. Additionally, base station 10 may also notify terminal 20 of the information related to the constraint as a UE-specific signal based on the UE capabilities received from terminal 20.

[0059] (Example 1) TAG

[0060] It can be envisioned that only actual CCs within the same TAG (Timing Advance Group) that contain and / or apply the same timing advance sequence can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0061] That is, the settings and / or commands involved in a specific timing advance can also be single (i.e., common) relative to the actual CC contained in the virtual CC.

[0062] Additionally, it can also support the case where actual CCs containing and / or applying different timing advance sequences in different TAGs constitute virtual CCs, and it can also specify the reporting of UE capability signaling that supports this configuration, and report it from terminal 20 to base station 10.

[0063] (Example 2) QCL

[0064] (Example 2a)

[0065] A Quasi-Co-Location (QCL) can be defined within an actual CC, and it is envisioned that only actual CCs within the QCL relationship can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0066] The settings and / or notifications involved in beam changes can also be single (i.e., public) relative to the actual CC contained in the virtual CC.

[0067] It can also support the case where a virtual CC is formed by an actual CC that is not in a QCL relationship, and it can also specify the reporting of UE capability signaling that supports such a formation, and report it from terminal 20 to base station 10.

[0068] (Example 2b)

[0069] It can be envisioned that only the following actual CCs can constitute the same virtual CC, which can centrally perform at least one of the following: settings / notifications / actions involved in handover; settings / notifications / actions related to measurement and reporting; and settings / notifications / actions related to Radio Link Monitoring (RLM) and Radio Link Failure (RLF). Here, settings / notifications / actions can be all of settings, notifications, and actions, or at least one of them. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0070] This setting / notification / action can also be a single (i.e., public) CC relative to the actual CC contained in the virtual CC.

[0071] It can also support the case where a virtual CC is constituted by an actual CC that independently performs the setting / notification / action, and it can also specify the reporting of UE capability signaling that supports the configuration, and report it from terminal 20 to base station 10.

[0072] (Example 3) Duplex configuration

[0073] (Example 3a)

[0074] It can be envisioned that actual CCs that are only set and / or notified of the same duplex mode (full-duplex communication mode, duplex mode, duplex mode) can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0075] That is, the settings and / or notifications involved in duplex mode can also be single (i.e., public) relative to the actual CC contained in the virtual CC.

[0076] The duplex mode can be any of Time Division Duplex (TDD), Frequency Division Duplex (FDD), Sub-Band Full Duplex (SBFD), or Full Duplex (FD), or other types of communication modes. Furthermore, SBFD and FD can be specifically applied to either base station 10 or terminal 20. For example, terminal 20 communicating with base station 10 can also use TDD or FDD, and base station 10 communicating with terminal 20 can also use TDD or FDD. The same applies in (Example 3).

[0077] It can also support the situation where a virtual CC is formed by an actual CC that has been set and / or notified of different duplex modes, and can also stipulate that the UE capability signaling supporting such a formation is reported and reported from the terminal 20 to the base station 10.

[0078] (Example 3b)

[0079] It can be envisioned that actual CCs configured with specific duplex modes can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0080] Figure 4 This is a diagram illustrating a structural example (3) of the virtual CC according to an embodiment of the present invention. Figure 4 As shown, for example, actual CC#0 is SBFD, actual CC#1 is TDD, actual CC#2 is SBFD, and virtual CC can be constructed from all actual CCs.

[0081] The terminal 20 may report a specific combination of supported duplex modes to the base station 10 and / or the base station 10 may report to the terminal 20.

[0082] (Example 3c)

[0083] Between the actual CCs contained within a specific virtual CC, the types of downlink (DL), uplink (UL), and flexible can differ. Flexible can refer to resources that can be used for both DL and UL based on scheduling. Either of the following two methods can be used here.

[0084] (Method 1) Prioritize any type within this category.

[0085] (Method 2) Execute multiple types of this type simultaneously.

[0086] For example, the choice between Method 1 and Method 2 can be determined based on the settings of base station 10. Alternatively, the choice can be determined based on the actual frequency gap between CCs. Or, the choice can be determined based on the UE capability.

[0087] (Example 3d)

[0088] SBFD (Sub-Band Full Duplex) can be executed in a virtual CC using any of the following methods.

[0089] (Method 1) Each actual CC is TDD and / or FDD, and the virtual CC is configured as SBFD.

[0090] (Method 2) Construct virtual CCs in a way that each actual CC can become an SBFD.

[0091] Here, SBFD is simply a structure in the virtual CC where the downlink (DL) sandwiches the uplink (UL) (i.e., a structure where there are UL resources between the DL resources in the frequency direction). In the actual CC, it does not have to be a structure where the downlink sandwiches the uplink.

[0092] (Example 4) Parameter Set (Numerology)

[0093] (Example 4a)

[0094] It can be envisioned that actual CCs using only the same set of parameters (numerology) can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0095] That is, the settings and / or commands involved in the parameter set (numerology) can also be single (i.e., common) relative to the actual CC contained in the virtual CC.

[0096] It can also support the case where a virtual CC is constructed from actual CCs using different sets of parameter (numerology), and can also specify the reporting of UE capability signaling that supports this construction, and report it from terminal 20 to base station 10.

[0097] (Example 4b)

[0098] It can be envisioned that actual CCs with only specific combinations of parameter sets (numerology) can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0099] For example, terminal 20 may envision that an actual CC with a subcarrier spacing (SCS) of 15 kHz and 30 kHz can constitute the same virtual CC. Alternatively, terminal 20 may envision that an actual CC with a subcarrier spacing of 15 kHz and 120 kHz does not constitute the same virtual CC. Furthermore, the supported parameter set (numerology) combination can be reported from terminal 20 to base station 10 and / or from base station 10 to terminal 20, or it can be reported from terminal 20 to base station 10.

[0100] (Example 4c)

[0101] The parameter sets (numerology) can be different among the actual CCs contained in a specific virtual CC, and actions in the virtual CC can be performed based on the parameter set (numerology) involved in any of the actual CCs. Alternatively, actions in each actual CC contained in the virtual CC can be performed based on the parameter set (numerology) involved in each actual CC.

[0102] (Example 5) Band / Band combination

[0103] (Example 5a)

[0104] It can be envisioned that only actual CCs contained in the same band can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0105] It can also support the case where virtual CCs are formed by actual CCs contained in different bands, and can also specify the reporting of UE capability signaling that supports this formation, and report it from terminal 20 to base station 10.

[0106] (Example 5b)

[0107] It can be envisioned that only actual CCs corresponding to specific band combinations can constitute the same virtual CC. For example, actual CCs corresponding to the combination of band A and band B can constitute the same virtual CC, and terminal 20 can use this virtual CC to perform communication with base station 10. For example, actual CCs corresponding to the combination of band A and band C may not constitute the same virtual CC, and terminal 20 can also envision that the virtual CC is not set.

[0108] (Example 5c)

[0109] It can be envisioned that only actual CCs within a specific distance on the frequency axis can constitute the same virtual CC. Here, the specific distance can be defined by specifications, or it can be notified by common signaling from base station 10, or it can be determined based on the UE capability. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0110] (Example 5-1) Licensed / unlicensed band

[0111] It can be envisioned that actual CCs of the same type, both licensed and unlicensed, can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0112] Alternatively, it can also support the situation where a virtual CC is composed of actual CCs of different types, namely licensed bands and unlicensed bands. It can also stipulate that the UE capability signaling supporting this composition is reported and reported from the terminal 20 to the base station 10.

[0113] (Example 6) Frequency range

[0114] (Example 6a)

[0115] It can be envisioned that only actual CCs contained within the same frequency range (FR) can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10. Alternatively, it is also possible to support the case where virtual CCs are constituted by actual CCs contained in different frequency ranges, and it is also possible to stipulate that UE capability signaling supporting such a configuration is reported from terminal 20 to base station 10.

[0116] (Example 6b)

[0117] It can be envisioned that only actual CCs corresponding to specific frequency range combinations (FR combinations) can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10. For example, only actual CCs corresponding to frequency range combinations {FR1, FR3} can constitute the same virtual CC, while actual CCs corresponding to frequency range combinations {FR3, FR2} may not constitute the same virtual CC. Furthermore, the supported frequency range combinations (FR combinations) can be reported from terminal 20 to base station 10 and / or from base station 10 to terminal 20, or reported from terminal 20 to base station 10.

[0118] (Example 6c)

[0119] The frequency range (e.g., FR3) can be divided into multiple segments, and Example 6b is applied to the segmented definitions. Figure 5 This is a diagram illustrating an example of the segmentation of the frequency range (FR3) according to an embodiment of the present invention. Figure 5 As shown, the frequency range of 7.125 GHz to 24 GHz, i.e., FR3, is divided into two frequency ranges: FR3a and FR3b. For example, only actual CCs corresponding to combinations of frequency ranges {FR1, FR3a} or {FR3b, FR2} can constitute the same virtual CC, while actual CCs corresponding to combinations of frequency ranges {FR1, FR3b} cannot constitute the same virtual CC. Furthermore, the supported frequency range combinations (FR combinations) can be reported from terminal 20 to base station 10, or from base station 10 to terminal 20.

[0120] The split location can be defined in the specification or set by base station 10 and / or terminal 20. For example, terminal 20 can implicitly determine the split location based on the synchronization signal (SS) sent by base station 10. Alternatively, the split location can be notified to terminal 20 through broadcast information (MIB (Master Information Block) and / or SIB (System Information Block)), downlink control information (DCI), and MAC (Medium Access Control) CE (Control Element) sent by base station 10.

[0121] (Example 6d)

[0122] Based on the frequency ranges used simultaneously, it can be assumed that the actual CCs that can constitute the same virtual CC are different. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0123] For example, when using FR1, FR3a, and FR3b simultaneously, it is conceivable that the actual CCs {FR1, FR3a, FR3b} can constitute virtual CCs.

[0124] Alternatively, for example, when using FR1, FR3a, FR3b, and FR2 simultaneously, it is conceivable that the actual CC of {FR1, FR3a} and {FR3b, FR2} can each constitute a virtual CC. In this case, it is conceivable that {FR1, FR3a, FR3b, FR2} cannot constitute a virtual CC.

[0125] (Example 7) RF (Radio Frequency)

[0126] It can be envisioned that actual CCs using only the same power control sequence can constitute the same virtual CC. Terminal 20 can also use this virtual CC to perform communication with base station 10.

[0127] That is, at least one of the definitions, settings, and commands (such as maximum transmit power, TPC command) involved in a specific power control can also be a single (i.e., common) relative to the actual CC contained in the virtual CC.

[0128] Alternatively, it can support the case where a virtual CC is formed by an actual CCC using different power control sequences, and it can also specify the reporting of UE capability signaling that supports this formation, and it can also report from terminal 20 to base station 10.

[0129] According to the above embodiments, discontinuous frequency resources can be used efficiently in wireless communication. Furthermore, by performing communication based on a virtual CC configuration limited to a feasible structure in both base station 10 and terminal 20, the complexity of specifications and installation of base station 10 and terminal 20 can be avoided, and flexibility is improved.

[0130] (Device structure)

[0131] Next, an example of the functional structure of the base station 10 and terminal 20 performing the processes and actions described above will be explained. The base station 10 and terminal 20 include the functions implemented in the above embodiments. However, the base station 10 and terminal 20 may each possess only a portion of the functions described in the embodiments.

[0132] <Base Station 10>

[0133] Figure 6 This is a diagram illustrating an example of the functional structure of base station 10 in an embodiment of the present invention. For example... Figure 6 As shown, the base station 10 includes a transmitting unit 110, a receiving unit 120, a setting unit 130, and a control unit 140. Figure 6 The functional structure shown is only one example. As long as the actions involved in the embodiments of the present invention can be performed, the functional distinctions and names of the functional units can be arbitrary. Alternatively, the transmitting unit 110 and the receiving unit 120 can be collectively referred to as the communication unit.

[0134] The transmitting unit 110 includes the function of generating a signal to be transmitted to the terminal 20 and wirelessly transmitting the signal. Additionally, the transmitting unit 110 transmits inter-network node messages to other network nodes. The receiving unit 120 includes the function of receiving various signals transmitted from the terminal 20 and obtaining, for example, higher-level information from the received signals. Furthermore, the transmitting unit 110 has the function of transmitting NR-PSS, NR-SSS, NR-PBCH, DL / UL control signals, etc., to the terminal 20. Additionally, the receiving unit 120 receives inter-network node messages from other network nodes.

[0135] The setting unit 130 stores preset setting information and various setting information sent to the terminal 20. The content of the setting information includes, for example, information related to discontinuous frequency resources.

Those skilled in the art should understand various modifications, alterations, substitutions, and replacements. Specific numerical examples have been used to facilitate understanding of the invention, but unless otherwise specified, these values ​​are merely examples, and any appropriate values ​​may be used. The distinctions between items in the above description are not essential to the present invention. Items described in two or more items may be combined as needed, and items described in one item may be applied to items described in another item (as long as there is no contradiction). The boundaries of functional units or processing units in the functional block diagram do not necessarily correspond to the boundaries of physical components. Multiple functional units may be operated by a single physical component, or a single functional unit may be operated by multiple physical components. Regarding the processing described in the embodiments, the order of processing may be interchanged unless there is a contradiction. For ease of explanation, a functional block diagram is used to illustrate the base station 10 and terminal 20, but such a device may also be implemented by hardware, software, or a combination thereof.

[0181] Furthermore, the notification of information is not limited to the forms / implementations described in this disclosure, and other methods may also be used.

[0183] The processing procedures, timing, and flow of the various forms / implementations described in this specification may be rearranged in order, provided there is no contradiction. For example, the elements of various steps are indicated using an illustrative order for the methods described in this disclosure, but are not limited to the specific order indicated.

[0184] In this specification, certain actions performed by base station 10 may sometimes also be performed by its upper node, depending on the circumstances. In a network consisting of one or more network nodes having base station 10, it is obvious that various actions performed to communicate with terminal 20 can be performed by at least one of base station 10 and other network nodes besides base station 10 (e.g., considering MME or S-GW, but not limited to these). The above example illustrates the case where there is one other network node besides base station 10, but other network nodes can also be a combination of multiple other network nodes (e.g., MME and S-GW).

[0185] The information or signals described in this disclosure can be output from a higher (or lower) layer to a lower (or higher) layer. They can also be input or output via multiple network nodes.

[0186] Input or output information can be stored in a specific location (e.g., memory) or managed using a management table. Input or output information can be overwritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0187] The determination in this disclosure can be made by a value represented by 1 bit (0 or 1), by a Boolean value (Boolean: true or false), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value).

[0188] Software, whether called software, firmware, middleware, microcode, hardware description language, or by other names, should be broadly interpreted as referring to commands, command sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0189] In addition, software, commands, information, etc., can be sent and received via a transmission medium. For example, when software is sent from a webpage, server, or other remote source using at least one of wired technologies (coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) etc.) and wireless technologies (infrared, microwave, etc.), at least one of these wired and wireless technologies is included within the definition of a transmission medium.

For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc., that may be involved in the above description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination of these.

[0191] Furthermore, the terms used in this disclosure and those necessary for understanding this disclosure may be replaced with terms that have the same or similar meanings. For example, at least one of the channel and symbol may also be a signal (signaling). Additionally, a signal may also be a message. Furthermore, a component carrier (CC) may also be referred to as carrier frequency, cell, frequency carrier, etc.

[0192] The terms “system” and “network” as used in this disclosure are used interchangeably.

[0193] Furthermore, the information, parameters, etc., described in this disclosure can be represented using absolute values, relative values ​​to predetermined values, or other corresponding information. For example, wireless resources can be indicated using indexes.

[0194] The names used for the above parameters are non-limiting in any respect. Furthermore, the formulas, etc., using these parameters sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by all appropriate names, therefore the various names assigned to these channels and information elements are non-limiting in any respect.

[0195] In this disclosure, the terms "base station (BS)," "wireless base station," "base station device," "fixed station," "NodeB," "eNodeB (eNB)," "gNodeB (gNB)," "access point," "transmission point," "reception point," "transmission / reception point," "cell," "sector," "cell group," "carrier," and "component carrier" are used interchangeably. Sometimes, terms such as macro cell, small cell, femtocell, and picocell are also used to refer to base stations.

[0196] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, its coverage area can be divided into several smaller areas, each of which can provide communication services through a base station subsystem (e.g., a small indoor cell tower (RRH: Remote Radio Head)). Terms such as "cell" or "sector" refer to a portion or all of the coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

[0197] In this disclosure, the base station sending information to the terminal can also be replaced by the base station instructing the terminal on information-based control / actions.

[0198] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" are used interchangeably.

[0199] For mobile stations, those skilled in the art sometimes also use the following terms: subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handheld device, user agent, mobile client, client, or some other appropriate terms.

[0200] At least one of the base station and mobile station can also be referred to as a transmitting device, receiving device, communication device, etc. Furthermore, at least one of the base station and mobile station can also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body refers to a movable object with an arbitrary speed of movement. It also includes situations where the mobile body is stationary. Examples of mobile bodies include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear cars, rickshaws, ships (ships and other watercraft), airplanes, rockets, artificial satellites, Drone (registered trademark), multi-rotor helicopters, quadcopter helicopters, balloons, and objects mounted on them. Additionally, the mobile body can also be a mobile body that moves autonomously based on operating commands. It can be a means of transportation (e.g., car, airplane), a mobile body that moves unmanned (e.g., drone, autonomous vehicle), or a robot (humanized or unmanned). Furthermore, at least one of the base station and mobile station also includes devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station can be an IoT (Internet of Things) device such as a sensor.

[0201] Furthermore, the base station in this disclosure can also be replaced by a user terminal. For example, the communication between the base station and the user terminal can be replaced by communication between multiple terminals 20 (e.g., D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.), and various forms / implementations of this disclosure can also be applied. In this case, the terminal 20 can also be configured to have the functions of the base station 10 described above. In addition, terms such as "uplink" and "downlink" can be replaced with terms corresponding to inter-terminal communication (e.g., "side"). For example, uplink channel, downlink channel, etc., can also be replaced with side channel.

[0202] Similarly, the user terminal in this disclosure can also be replaced by a base station. In this case, the base station can also be configured to have the functions of the aforementioned user terminal.

[0203] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of actions. For example, "determining" or "determining" may include actions such as judging, calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and ascertaining, which are considered as actions of "determining" or "determining." Furthermore, "determining" or "determining" may include actions such as receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in memory), which are considered as actions of "determining" or "determining." Additionally, "determining" or "determining" may include actions such as resolving, selecting, choosing, establishing, and comparing, which are considered as actions of "determining" or "determining." That is, "judgment" and "decision" can include matters that are considered as having been "judged" or "decided". In addition, "judgment (decision)" can also be replaced by "assuming", "expecting", "considering", etc.

[0204] The terms “connected,” “coupled,” or any variations thereof are intended to indicate any direct or indirect connection or combination between two or more elements, including cases where there is one or more intermediate elements between the two elements that are “connected” or “coupled.” The combination or connection between elements can be physical, logical, or a combination of these. For example, “access” can be used instead of “connected.” In the context of this disclosure, it can be understood that two elements are “connected” or “coupled” to each other using at least one of one or more wires, cables, and printed electrical connections, and, as some non-limiting and non-inclusive examples, using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (including both visible and invisible regions) to “connect” or “couple” to each other.

[0205] The reference signal can be simply called RS (Reference Signal), or, depending on the standard applied, pilot.

[0206] As used in this disclosure, the word "based on" does not mean "based on only" unless otherwise expressly stated. In other words, the word "based on" means both "based on only" and "based on at least".

[0207] Any reference to elements using the designations "first," "second," etc., as used in this disclosure does not necessarily limit the number or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, references to the first and second elements do not imply that only two elements can be taken, or that the first element must precede the second element in any form.

[0208] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0209] When the terms "include," "including," and their variations are used in this disclosure, these terms, like the term "comprising," imply inclusion. Furthermore, the term "or" as used in this disclosure does not refer to XOR.

[0210] A radio frame can consist of one or more frames in the time domain. Each frame in the time domain can be called a subframe. A subframe can also consist of one or more time slots in the time domain. A subframe can be a fixed duration (e.g., 1 ms) independent of the parameter set (numerology).

[0211] A parameter set can be communication parameters applied to at least one of the transmission and reception of a signal or channel. For example, a parameter set can represent 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 structure, specific filtering processing performed by the transceiver in the frequency domain, and specific windowing processing performed by the transceiver in the time domain.

[0212] In the time domain, a time slot can be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A time slot can be a time unit based on a set of parameters.

[0213] A time slot can contain multiple mini-time slots. Each mini-time slot can consist of one or more symbols in the time domain. Additionally, a mini-time slot can also be called a sub-time slot. A mini-time slot can consist of fewer symbols than a time slot. PDSCH (or PUSCH) transmitted in time units larger than mini-time slots can be called PDSCH (or PUSCH) mapping type (type) A. PDSCH (or PUSCH) transmitted using mini-time slots can be called PDSCH (or PUSCH) mapping type (type) B.

[0214] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols can each be referred to by other corresponding names.

[0215] For example, a subframe can be called a Transmission Time Interval (TTI), multiple consecutive subframes can also be called a TTI, and a time slot or a mini-time slot can also be called a TTI. That is to say, at least one of a subframe and a TTI can be a subframe (1ms) in existing LTE, a period shorter than 1ms (e.g., symbols 1-13), or a period longer than 1ms. Furthermore, the unit representing TTI may not be called a subframe, but rather a time slot, mini-time slot, etc.

[0216] Here, TTI refers, for example, to the smallest unit of time for scheduling in wireless communication. For instance, in an LTE system, the base station schedules the allocation of radio resources (bandwidth, transmit power, etc., available to each terminal 20) in units of TTI. However, the definition of TTI is not limited to this.

[0217] The Time Interval (TTI) can be a unit of time for transmitting channel-coded data packets (transmission blocks), code blocks, codewords, etc., or it can be a processing unit such as scheduling or link adaptation. Furthermore, when a TTI is given, the actual time interval (e.g., the number of symbols) that the transmission block, code block, codeword, etc., are mapped to can be shorter than the TTI.

[0218] Furthermore, when one time slot or one mini time slot is referred to as a TTI, more than one TTI (i.e., more than one time slot or more than one mini time slot) can become the minimum time unit for scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit for scheduling can also be controlled.

[0219] A TTI with a duration of 1ms can also be called a normal TTI (TTI in LTE Rel.8-12), a long TTI, a normal subframe, a long subframe, or a time slot. A TTI shorter than a normal TTI can also be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini time slot, a sub-time slot, or a time slot.

[0220] Furthermore, for long TTIs (e.g., normal TTIs, subframes, etc.), they can be replaced with TTIs with a duration of more than 1ms. For short TTIs (e.g., shortened TTIs, etc.), they can be replaced with TTIs with a duration of less than long TTIs but more than 1ms.

[0221] A resource block (RB) is a unit of resource allocation in both the time and frequency domains. In the frequency domain, it can contain one or more consecutive subcarriers. The number of subcarriers contained in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers contained in an RB can also be determined based on the parameter set.

[0222] In addition, the time domain of an RB can contain one or more symbols, which can be a time slot, a mini-time slot, a subframe, or a TTI in length. A TTI, a subframe, etc., can each be composed of one or more resource blocks.

[0223] In addition, one or more RBs can also be called Physical Resource Block (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB Pair, RB Pair, etc.

[0224] In addition, a resource block can consist of one or more resource elements (REs). For example, one RE can be a radio resource area consisting of one subcarrier and one symbol.

[0225] The Bandwidth Part (BWP) (also known as partial bandwidth, etc.) can also represent a subset of contiguous common resource blocks (RBs) used for a certain parameter set in a certain carrier. Here, common RBs can be determined by indexing RBs based on a common reference point of that carrier. PRBs can be defined and numbered within a BWP.

[0226] A BWP can include a UL BWP and a DL BWP. One or more BWPs can be set for a UE within a single carrier.

[0227] At least one of the configured BWPs can be active, and the UE may not intend to transmit or receive predetermined signals / channels outside of the active BWP. Furthermore, the terms "cell," "carrier," etc., used in this disclosure can be replaced with "BWP."

[0228] The structures of radio frames, subframes, time slots, mini-time slots, and symbols described above are merely illustrative. For example, the number of subframes contained in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots contained within a time slot, the number of symbols and RBs contained in a time slot or mini-time slot, the number of subcarriers contained in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, and other structures can be varied in many ways.

[0229] In this disclosure, for example, in cases where articles are added through translation, such as in English (e.g., a, an, and the), this disclosure may also include cases where the noun following these articles is in a plural form.

[0230] In this disclosure, the phrase "A and B are different" can mean "A and B are not the same." Furthermore, this phrase can also mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."

[0231] The various forms / implementations described in this disclosure can be used individually or in combination, and can be switched depending on the execution. Furthermore, the notification of predetermined information (e.g., a "It is X" notification) is not limited to being explicit, but can also be implicit (e.g., not notifying the predetermined information).

[0232] The present disclosure has been described in detail above, but 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 as modifications and variations without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the present disclosure is for illustrative purposes only and is not intended to be limiting.
