Description

Technical Field

[0001] This invention relates to communication devices 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, accelerate data transmission speeds, and reduce latency in the radio space. Within 5G, various wireless technologies were researched to meet the requirement of achieving throughput exceeding 10Gbps while maintaining latency below 1ms in the radio space.

[0003] In NR, a network architecture including 5GC (5G Core Network) and NG-RAN (Next Generation-Radio Access Network) is being studied. The 5GC corresponds to the core network EPC (Evolved Packet Core) in the LTE (Long Term Evolution) network architecture, and the NG-RAN corresponds to the RAN (Radio Access Network) E-UTRAN (Evolved Universal Terrestrial Radio Access Network) in the LTE network architecture (e.g., Non-Patent Literature 1 and Non-Patent Literature 2).

[0004] Furthermore, for the realization of 6G, requirements related to ultra-high speed, high-capacity communication, ultra-wide coverage, ultra-low power consumption, low cost, ultra-low latency, ultra-high reliability of notification, and ultra-high connectivity / sensing are presented. Additionally, polar coding is a candidate for error correction codes, which is one of the important technological elements being researched to meet these requirements.

[0012] In NR, polar coding is employed (see Non-Patent Literature 3 and Non-Patent Literature 4). In particular, when the codeword length is short, polar coding, as a candidate for error correction codes studied for the realization of 6G, is difficult to improve performance.

[0029] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the embodiments described below are merely examples, and the application of the present invention is not limited to the embodiments described below.

[0030] 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).

[0031] 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-".

[0032] 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).

[0033] 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.

[0034] Figure 1 This is a diagram illustrating an example structure 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.

[0035] 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.

[0036] 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 1 As 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.

[0037] Furthermore, various requirements for next-generation 6G were further investigated. For example, these requirements could include ultra-broadband communication, mission-critical communication, ultra-massive connection, universal coverage, intelligent connection, and ubiquitous sensing.

[0038] In addition, this requirement can also include ultra-high-speed communication, high-capacity communication, ultra-wide coverage, ultra-low power consumption, low cost, ultra-low latency, ultra-high reliability communication, ultra-multiple connections, and sensing.

[0039] To achieve this requirement, a new concept is being developed that aims to be extensible (e.g., able to be used effectively in the future), easy-operational, customizable (e.g., easier to use), and sustainable (e.g., cost reduction, becoming a more robust structure, and having resilience). Additionally, as a form of guaranteed communication, research is underway to consistently guarantee minimum performance.

[0040] Furthermore, the implementation of 6G presents requirements related to ultra-high speed, high-capacity communication, extended coverage, ultra-low power consumption, low cost, ultra-low latency, ultra-high reliability of notification, and massive connectivity / sensing. Additionally, polar coding (also known as polar codes) is a candidate for error correction codes, which is one of the key technologies being researched to meet these requirements.

[0041] Polar coding can achieve error rate characteristics that gradually approach the Shannon limit by using channel polarization, and it has been used as an error correction code for the control channel in 5G NR. Furthermore, it is also being studied as a strong candidate for error correction coding towards 6G.

[0042] Figure 2 This is a diagram used to illustrate an example of communication channel polarization. For example... Figure 2 As shown, channel polarization refers to combining and splitting channels of the same quality (uniform original channels) to convert them into polarized new channels.

[0043] In addition, as variations of polarization coding, there are two other types: convolutional polarization coding and relaxed polarization coding. Convolutional polarization coding promotes channel polarization by introducing a convolutional structure (adding an XOR operation) without changing the codeword length. On the other hand, relaxed polarization coding reduces computation and eliminates the generation of unnecessary poor channel polarization by stopping unnecessary channel polarization (removing the XOR operation).

[0044] Figure 3 This is a diagram used to illustrate polarization coding. For example... Figure 3 As shown, in XOR-based channel polarization in polar coding, as the codeword length increases, polarization progresses towards both poor and good channels, thereby improving performance related to the error rate per unit of information bits. However, with short codeword lengths, polarization decreases, thus limiting performance improvement.

[0045] Figure 4 and Figure 5 These are the first and second diagrams used to illustrate volume active coding. For example... Figure 4 and Figure 5 As shown, in convolutional polarization coding, by adding an XOR operation to the encoder, polarization can be improved compared to conventional polar codes.

[0046] Figure 6 and Figure 7 These are the first and second diagrams used to illustrate volume active coding. For example... Figure 6 and Figure 7 As shown, in relaxed polarization coding, if the channel meets certain quality requirements, polarization is stopped by removing the XOR operation from the encoder. That is, if the quality is excessive, there is no need to create a poor channel, so the quality is maintained by not performing polarization.

[0047] (Example)

[0048] Examples will be described. In this example, a method for improving performance in short codeword lengths by combining convolutional polarization codes and relaxed polarization codes will be described. Furthermore, this example describes a method related to extended polarization coding (extended polarization codes) in a wireless communication system, which includes a channel polarization enhancement function based on XOR operations and a channel polarization deleting function based on XOR operations. Additionally, the polarization coding method, encoder, and encoding settings described in this example are also applicable to methods for decoding encoded codewords, decoders, and decoding settings.

[0049] (First embodiment)

[0050] In the first embodiment, a code generation method is described in which channel polarization is promoted by appending an XOR operation in polarization coding, and the XOR operation is removed to stop polarization once a certain channel quality is achieved.

[0051] The method in the first embodiment can promote channel polarization even when the codeword length is short by adding XOR operations. In addition, by stopping the polarization of the channel that has reached a certain quality, the generation of unnecessary bad channels is suppressed, thereby improving the performance of polarization coding.

[0052] (First Method)

[0053] Base station 10 and terminal 20 may also determine the additional position of XOR operation in encoder for facilitating channel polarization in polarization coding based on at least one of the methods shown below.

[0054] (Method 1-1)

[0055] Base station 10 and terminal 20 can also use XOR operation append rules predefined according to standards, etc. For example, the XOR operation append rules can be specified in the form of a code generation matrix, or the operation processing of each bit in the codeword can be specified.

[0056] (Method 1-2)

[0057] Base station 10 and terminal 20 may also use XOR operation appending modes predefined according to standards, etc. For example, as an XOR operation appending mode, the structure diagram of an encoder with polar coding appended with XOR operation may be explicitly specified.

[0058] (Second method)

[0059] Base station 10 and terminal 20 may also determine the quality of the channel when the channel polarization in relaxed polarization coding is stopped (XOR operation deletion) based on at least one of the methods shown below.

[0060] (Method 2-1)

[0061] Base station 10 and terminal 20 set the quality of the channel in the polarization coding to be above a certain threshold when the channel capacity of the good channel is above a certain threshold. That is, base station 10 and terminal 20 can also stop the channel polarization in the polarization coding when the channel capacity of the good channel is above a certain threshold.

[0062] (Method 2-2)

[0063] Base station 10 and terminal 20 set the channel quality for stopping channel polarization in polarization coding to be below a determined threshold where the error rate in a good channel is below a certain threshold. That is, base station 10 and terminal 20 can also stop channel polarization in polarization coding if the error rate in a good channel is above the determined threshold.

[0064] (Method 2-3)

[0065] Base station 10 and terminal 20 set the channel quality for stopping channel polarization in polarization coding to be below a certain threshold for the channel capacity of a poor channel. That is, base station 10 and terminal 20 can also stop channel polarization in polarization coding when the channel capacity of a poor channel is below a certain threshold.

[0066] (Methods 2-4)

[0067] Base station 10 and terminal 20 set the channel quality for stopping channel polarization in polarization coding to be above a certain threshold where the error rate in a poor channel is above a certain threshold. That is, base station 10 and terminal 20 can also stop channel polarization in polarization coding when the error rate in a poor channel is above a certain threshold.

[0068] Furthermore, in methods 2-1 to 2-4 described above, the channel capacity and error rate can be calculated based on theoretical values ​​or pre-calculated using numerical calculations based on simulators, etc. Additionally, the threshold can be determined based on the desired quality, or it can be changed based on the coding rate or the modulation scheme. Moreover, the threshold can be predetermined based on standards, or it can be set by the base station 10 and the terminal 20.

[0069] (Third method)

[0070] Base station 10 and terminal 20 may also determine the deletion position of XOR operation in encoder for stopping channel polarization (XOR operation deletion) in polarization coding based on at least one of the methods shown below.

[0071] (Method 3-1)

[0072] Base station 10 and terminal 20 may also use XOR operation deletion rules that are predefined according to standards or the like and are based on threshold determination in the second method. For example, as XOR operation deletion rules, they may be specified in the form of a code generation matrix, or the operation processing of each bit in the codeword may be specified.

[0073] (Method 3-2)

[0074] Base station 10 and terminal 20 may also use an XOR operation deletion mode that is predefined according to standards or the like and determined based on a threshold in the second method. For example, as an XOR operation deletion mode, the structure diagram of the encoder with polar coding that has deleted the XOR operation may also be explicitly specified.

[0075] (Fourth method)

[0076] In polarization coding, base station 10 and terminal 20 can apply both the append operation to promote channel polarization and the delete operation to stop channel polarization, or they can apply only one of them.

[0077] (Fifth Method)

[0078] Base station 10 and terminal 20 may also define the signal, channel and encoded information involved in the polar coding method in this embodiment.

[0079] For example, it can be limited to uplink control information (UCI) containing feedback information (HARQ-ACK, Hybrid Automatic Repeat request-Acknowledgement), limited to UCI containing channel state information (CSI), limited to downlink control channel (PDCCH), limited to PDCCH containing a payload of a specified size (e.g., more than X bits), and limited to downlink data channel (PDSCH) and / or uplink data channel (PUSCH), etc.

[0080] Furthermore, base station 10 and terminal 20 may simultaneously support polar coding specified in 5G NR Rel-15 and extended polar coding based on the method in this embodiment, or they may only support extended polar coding based on the method in this embodiment.

[0081] (Second Embodiment)

[0082] In the second embodiment, setting information related to the extended polar coding described in the first embodiment and a method for notifying the setting information are explained.

[0083] Using the method shown in the second embodiment, the same setting information related to the extended polar coding described in the first embodiment can be used between multiple communication devices (e.g., from base station 10 to terminal 20, from terminal 20 to base station 10, between multiple terminals 20, etc.).

[0084] (First Method)

[0085] Between communication devices, setting information related to polarization coding can also be communicated using the methods shown below.

[0086] (Method 1-1)

[0087] Base station 10 and terminal 20 can also use the RRC (Radio Resource Control) protocol to notify configuration information related to polarization coding.

Here, information bits and frozen bits (also referred to as virtual bits or known bits) are bits in a polar-coded codeword that are transmitted using a good channel and bits that are transmitted using a bad channel, respectively. Furthermore, the reliability table has values ​​representing the reliability of each bit in a polar-coded codeword; for example, bits with a reliability above a determined threshold are treated as information bits.

[0110] (Third method)

[0111] When base station 10 and terminal 20 are configured with setting information related to the extended polar coding described in the first embodiment, and / or are notified of such setting information, at least one processing time, as shown below, may also be conceivable to be shorter than the processing time conceivable in polar coding in existing standards.

[0112] (Method 3-1)

[0113] Base station 10 and terminal 20 can also envision shorter decoding times for downlink control channel (PDCCH) and / or downlink control information (DCI). Here, the decoding time of PDCCH and / or DCI can be replaced by the default beam time.

[0122] (Methods 3-6)

[0123] Base station 10 and terminal 20 can also be designed to have a shorter decoding time for uplink data channel (PUSCH).

[0124] (Third embodiment)

[0125] In the third embodiment, when using the extended polar coding described in the first embodiment, the base station 10 and the terminal 20 may have multiple code structures with different XOR append and / or deletion positions if different qualities are required according to specific conditions. For example, having multiple code structures may also be achieved by using multiple setting information related to polar coding.

[0126] Therefore, by applying the optimal polar coding structure according to the conditions, the performance of polar coding can be improved.

This threshold is, for example, the threshold used in the second method (methods 2-1 to 2-4) of the first embodiment.

[0159] (Methods 3-8)

[0160] Base station 10 and terminal 20 may also include information related to the index of a reliability table representing each codeword bit used to determine the position of information bits and / or frozen bits as setting information associated with polar coding. Here, information bits and frozen bits (virtual bits) are bits in a polar-coded codeword that are transmitted using a good channel and bits that are transmitted using a bad channel, respectively. Furthermore, the reliability table has values ​​representing the reliability of each bit in a polar-coded codeword, for example, treating bits with a reliability above a determined threshold as information bits.

[0161] In addition, in this embodiment, the frozen bit can also be referred to as a known bit (e.g., 0 or 1 as a known bit) that is appended when encoding information bits based on polar codes.

[0163] Furthermore, the extended polar coding described in this embodiment can also be defined as a mandatory function (Mandatory with UE capability signaling) in 6G (e.g., a RAT-related standard different from 5G NR introduced after Rel-20), or it can be defined as an optional function (Optional with UE capability signaling) in 5G NR and / or 6G. Here, the UE capability signaling described in this embodiment, in which the terminal 20 reports information related to supporting the extended polar coding to the base station 10, can also be defined.

The receiving unit 220 wirelessly receives various signals and obtains higher-layer signals from the received physical layer signals. Furthermore, the receiving unit 220 has the function of receiving NR-PSS, NR-SSS, NR-PBCH, DL / UL / SL control signals, etc., transmitted from the base station 10. Additionally, for example, as D2D communication, the transmitting unit 210 transmits PSCCH (Physical Sidelink Control Channel), PSSCH (Physical Sidelink Shared Channel), PSDCH (Physical Sidelink Discovery Channel), PSBCH (Physical Sidelink Broadcast Channel), etc., to other terminals 20, and the receiving unit 220 receives PSCCH, PSSCH, PSDCH, or PSBCH from other terminals 20.

[0175] The setting unit 230 stores various setting information received from the base station 10 by the receiving unit 220. In addition, the setting unit 230 also stores preset setting information. The content of the setting information includes, for example, information related to polarization coding settings.

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.

[0217] Furthermore, the notification of information is not limited to the forms / implementations described in this disclosure, and other methods may also be used. For example, information notification may be implemented through physical layer signaling (e.g., DCI (Downlink Control Information), UCI (Uplink Control Information)), higher layer signaling (e.g., RRC (Radio Resource Control) signaling, MAC (Medium Access Control) signaling), broadcast information (MIB (Master Information Block), SIB (System Information Block)), other signals, or combinations thereof.

[0219] 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.

[0220] 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).

[0221] 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.

[0222] 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.

[0223] 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).

[0224] 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.

[0225] 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.

[0227] 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.

[0228] The terms “system” and “network” as used in this disclosure are used interchangeably.

[0229] 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 also be indicated using indexes.

[0230] 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.

[0231] 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.

[0232] 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 also provide communication services through a base station subsystem (e.g., a small indoor base station (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.

[0233] 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.

[0234] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" are used interchangeably.

[0235] 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.

[0236] At least one of the base station and the mobile station can also be referred to as a transmitting device, a receiving device, a communication device, etc. Furthermore, at least one of the base station and the mobile station can also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body refers to an object capable of movement, with an arbitrary speed. 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, shovel cars, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear cars, rickshaws, ships and other watercraft, airplanes, rockets, artificial satellites, drones (registered trademark), multicopters, quadcopters, balloons, and objects mounted on them. Additionally, the mobile body can also be a mobile body that moves autonomously based on operating commands. This can be a means of transportation (such as a car, airplane, etc.), a mobile entity that moves unmanned (such as a drone, self-driving car, etc.), or a robot (humanized or unmanned). Furthermore, at least one of the base station and mobile station may also include a device that does not necessarily move during communication. For example, at least one of the base station and mobile station may be an IoT (Internet of Things) device such as a sensor.

[0237] 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 communication between terminals (e.g., "side"). For example, uplink channel, downlink channel, etc. can also be replaced with side channel.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] The reference signal can be simply called RS (Reference Signal), or, depending on the standard applied, pilot.

[0242] 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".

[0243] 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.

[0244] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0245] 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.

[0246] 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.

[0247] 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."
