[0044] The following description, with reference to the accompanying drawings, illustrates one embodiment of this disclosure. Furthermore, the embodiments described below are merely examples, and the application of this disclosure is not limited to the following embodiments.

[0045] In the operation of the wireless communication system according to the embodiments of this disclosure, existing technology is appropriately used. Although the existing technology is, for example, existing LTE, it is not limited to existing LTE. Furthermore, the term "LTE" as used in this specification is, without particular negation, defined as having a broader meaning that includes LTE-Advanced and subsequent forms of LTE evolution (e.g., NR).

[0046] Furthermore, in the embodiments of this disclosure described below, 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) used in existing LTE are used. This is for ease of description; signals, functions, etc., that are the same as these can also be referred to by other names. In addition, the above terms in NR correspond to NR-SS, NR-PSS, NR-SSS, NR-PBCH, and NR-PRACH. However, even signals used in NR do not necessarily have to be explicitly written as "NR-".

[0047] Furthermore, in the embodiments of this disclosure, the duplex mode can be either TDD (Time Division Duplex), FDD (Frequency Division Duplex), or other modes (e.g., Flexible Duplex).

[0048] Furthermore, in embodiments of this disclosure, "configure" of wireless parameters, etc., can refer to either specific values ​​being pre-configured or wireless parameters being set as notified from a base station or a terminal containing the device.

[0049] <System Structure>

[0050] Figure 1 This is a diagram illustrating an example structure of a wireless communication system according to an implementation method. For example... Figure 1 As shown, the wireless communication system includes a base station 10 and a device 20. Figure 1 The image shows one base station 10 and one device 20, but this is just one example; there can be multiple devices. Device 20 can also be an environmental IoT device.

[0051] Base station 10 provides one or more cells and is a communication device for wireless communication with device 20. The physical resources of the wireless signal are defined in the time domain and frequency domain. The time domain can also be defined by the number of OFDM (Orthogonal Frequency Division Multiplexing) symbols. The frequency domain can also be defined by the number of subcarriers or resource blocks.

[0052] Base station 10 sends synchronization signals and system information to device 20. Base station 10 sends control signals and data to device 20 via DL (Downlink). Base station 10 receives control signals and data from device 20 via UL (Uplink).

[0053] As described below, wireless communication systems may also include intermediate nodes and / or assisting nodes (see <Device Types and Topologies> below). Hereinafter, "and / or" will sometimes be abbreviated as " / ".

[0054] <Environmental IoT>

[0055] In Rel-18, research related to environmental IoT (e.g., see section 10 of Non-Patent Document 4) that is lower-end than existing Narrow Band IoT (NB-IoT: e.g., see section 10 of Non-Patent Document 4) is recognized (e.g., see Non-Patent Document 2). In environmental IoT, the goal is to develop ultra-low power consumption and ultra-low complexity devices.

[0056] In environmental IoT, for example, for associated use cases, the following import scenarios and characteristics can be studied.

[0057] Indoor or outdoor environment

[0058] • Base station type, for example, configuration based on macro / micro / pico cells.

[0059] • Connectivity-related topology, such as whether any node, including base stations, user terminals (UEs), relays, and repeaters, communicates with environmental IoT devices.

[0060] • Is the duplex mode TDD or FDD? Is the frequency band licensed or unlicensed?

[0061] • Coexistence of UEs and network equipment in frequency bands for existing 3GPP technologies

[0062] • Conceptualization of services originating from / calling to the device

[0063] Based on the above-mentioned import scenarios and characteristics, RAN design goals can be formulated as follows.

[0064] Power consumption

[0065] Complexity

[0066] • Coverage

[0067] Data rate

[0068] • Positioning accuracy

[0069] Based on the import scenarios applicable to the associated use cases, the feasibility of achieving the design goals is compared and evaluated to determine the supported functions.

[0070] <Device Type and Topology>

[0071] Based on the results of the study item, TR 38.848 (Non-Patent Document 3) is approved. In TR 38.848, environmental IoT devices of the following category are being studied.

[0072] Device A: Device A does not have energy storage, nor does it have independent signal generation and signal amplification functions. Device A performs backscattering transmission.

[0073] Device B: Device B has power storage but does not have independent signal generation capabilities. Device B performs backscatter transmission. Device B uses the stored power to amplify the reflected signal.

[0074] Device C: Device C has power storage and independent signal generation capabilities. That is, Device C has an active RF component for transmission.

[0075] In addition, regarding the complexity of device A, consider the level of radio frequency identification (RFID).

[0076] In TR 38.848, in the context of the IoT network, the following topologies 1-4 are defined.

[0077] Figure 2 This is a diagram illustrating Topology 1. Topology 1 is as follows: Figure 2 The diagram shows the structure for communication between a base station (BS) and environmental IoT devices. The environmental IoT devices directly communicate bidirectionally with the base station.

[0078] Figure 3 This is a diagram illustrating Topology 2. Topology 2 is as follows: Figure 3 The diagram illustrates the communication structure between a base station and an environmental IoT device via an intermediate node. The environmental IoT device communicates bidirectionally with the intermediate node configured between the base station and the environmental IoT device. The intermediate node can be, for example, a relay, an Integrated Access and Backhaul (IAB) node, a UE, or a repeater.

[0079] Figure 4 This is a diagram illustrating Topology 3 in DL-assisted programming. Topology 3 is as follows: Figure 4 The diagram shows the structure that includes communication between the base station and the assistant node, communication between the assistant node and the environmental IoT device, and communication between the environmental IoT device and the base station.

[0080] Auxiliary nodes assist in deep communication. For example, such as... Figure 4 As shown, the auxiliary node receives the DL signal from the base station and transmits it to the environmental IoT device. In the UL signal, the environmental IoT device transmits directly to the base station.

[0081] Figure 5 This is a diagram illustrating topology 3 in UL-assisted implementation. For example... Figure 5 As shown, Topology 3 is a structure that includes communication between the base station and auxiliary nodes, communication between auxiliary nodes and environmental IoT devices, and communication between environmental IoT devices and the base station.

[0082] Auxiliary nodes assist UL communication. For example, such as... Figure 5As shown, the auxiliary node receives the UL signal from the environmental IoT device and transmits it to the base station. In the DL signal, the environmental IoT device receives it directly from the base station.

[0083] Figure 4 and Figure 5 The auxiliary node shown can also emit a carrier wave that causes environmental IoT devices to generate backscattered signals. The auxiliary node can be, for example, a relay, an IAB node, a UE, or a repeater.

[0084] Figure 6 This is a diagram illustrating Topology 4. Topology 4 is the structure for communication between the UE and the environmental IoT devices. The environmental IoT devices and the UE perform bidirectional communication. Topology 4 can be understood as sidelink (SL) communication.

[0085] In addition, in the topologies 1 to 4 described above, carrier waves can also be provided to the environmental IoT devices from other nodes inside or outside the topology (Section 4.2.1 of Non-Patent Document 3).

[0086] <Backscatter transmission>

[0087] Base stations, intermediate nodes, auxiliary nodes, and other nodes send RF signals to environmental IoT devices. The environmental IoT devices are activated and obtain power from the RF operating field from the base stations, intermediate nodes, auxiliary nodes, and other nodes via inductive coupling.

[0088] Environmental IoT devices backscatter modulation of RF signals received from base stations, intermediate nodes, auxiliary nodes, and other nodes by switching the reflection coefficient of their own antennas, and then send information to base stations, intermediate nodes, auxiliary nodes, and other nodes.

[0089] Figure 7 This is a diagram illustrating backscattering. In Figure 7 The image shows an example of an environmental IoT device sending information by performing ON-OFF keying. Alternatively, it could be... Figure 7 The area indicated by the dashed line represents the OFF interval, corresponding to the "0" in information (bits). A sine wave signal can also correspond to the "1" in information.

[0090] The network may also include base stations, auxiliary nodes, intermediate nodes, and terminals (UEs in Topology 4). Hereinafter, base stations, auxiliary nodes, intermediate nodes, relays, and terminals will sometimes be referred to as network nodes. Environmental IoT is sometimes referred to as A-IoT. A-IoT devices are sometimes referred to as A-IoT UEs.

[0091] <Rel-19 Study Item Description (SID)>

[0092] In the SID of Rel-19, solutions necessary and achievable for A-IoT were studied (section 4.1 of Non-Patent Document 5). Among the studied solutions, for example, it includes determining which functions, processes, etc. are necessary and which are unnecessary.

[0093] In addition, for the DL and UL of A-IoT, several matters were discussed mainly by RAN 1. One of the discussed matters is the scheduling and timing relationship of DL and UL in A-IoT. In the discussion of the scheduling and timing relationship, the following 1. service process, 2. device premise (device assumption), and 3. topology can be studied.

[0094] 1. Service process

[0095] As the service process of A-IoT, the following DT and DO-DTT are being studied.

[0096] · DT (device terminated)

[0097] As a service, there is transmission to the A-IoT UE (DL), and there is no transmission from the A-IoT UE (UL). In other words, there is information transmitted to the A-IoT UE, and there is no information transmitted from the A-IoT UE. DT corresponds, for example, to a command type with an indication such as an instruction or command to the A-IoT UE.

[0098] · DO-DTT (device originated–device terminated triggered)

[0099] As a service, there is a trigger from the network (NW), and there is transmission from the A-IoT UE (UL). In other words, as a service, there is information transmitted from the A-IoT UE. DO-DTT corresponds, for example, to a sensor information report type for transmitting the sensor information collected by the A-IoT UE.

[0100] Furthermore, in this disclosure, the transmission of information corresponds to the transmission of a signal containing information, or the transmission of a signal. Additionally, in this disclosure, transmission to a device X corresponds to the transmission of a signal (or information) to device X. Furthermore, transmission from a device X and transmission from a device X correspond to the transmission of a signal (or information) by device X. Furthermore, reception from a device X corresponds to the reception of a signal (or information) transmitted by receiving device X. Furthermore, reception from a device X corresponds to the reception of a signal (or information) by device X.

[0101] 2. Equipment prerequisites

[0102] In A-IoT UE, the following TX (transmit) and FR (frequency range) 1-FDD are assumed.

[0103] ·TX

[0104] TX is either a backscattered UL transmission without amplification, or a general UL transmission with amplification. Alternatively, a UL transmission with amplified backscattering can also be performed.

[0105] ·FR1-FDD

[0106] FR1-FDD is applied to A-IoT UEs. That is, A-IoT UEs can switch carrier frequencies between the carrier of the DL and the carrier of the UL. However, this disclosure is not limited to FR1-FDD, and can be applied to TDD, as well as FR2 or FR3.

[0107] In addition, the frequency bands of each FR are as follows.

[0108] FR1: 410MHz~7.125GHz

[0109] FR2: 24.25GHz~52.6GHz

[0110] FR3: 7.125GHz~24.25GHz

[0111] In FR1, sub-carrier spacing (SCS) of 15kHz, 30kHz, or 60kHz can be used, with a bandwidth of 5~100MHz (BW). FR2 has a higher frequency than FR1 and can also use SCS of 60kHz or 120kHz (including 240kHz), with a bandwidth of 50~400MHz (BW).

[0112] 3. Topology

[0113] exist Figures 2-6Of the topologies shown, topology 1 and topology 2 are of particular interest.

[0114] In Topology 1, UL and / or DL ​​communication is performed between the base station and the A-IoT UE without going through intermediate nodes. Additionally, the base station in Topology 1 can also correspond to a microcell.

[0115] In Topology 2, communication occurs between the base station and the A-IoT UE via an intermediate node. The A-IoT UE and the intermediate node configured between the base station and the A-IoT UE perform bidirectional communication. Furthermore, the base station in Topology 2 can also correspond to a macro cell. Additionally, Topology 2 can also be applied to indoor scenarios. Hereinafter, the intermediate node is sometimes referred to as int. UE (intermediate UE).

[0116] <Communication process>

[0117] Between Topology 1 and Topology 2, the signal design for A-IoT UEs can also be designed to be common. To make the signal design for A-IoT UEs common, the communication flow of DT and DO-DTT in Topology 1 and Topology 2 can be studied. As the communication flow of DT and DO-DTT in Topology 1 and Topology 2, the following four communication flows can be envisioned.

[0118] Additionally, as shown in the four communication processes 1 to 4 below, the A-IoT UE is woken up in step 1 and receives information in step 2. The information received by the A-IoT UE can also be rewritten as signals.

[0119] Furthermore, as shown in the communication flow diagrams 2. and 4. below, the A-IoT UE transmits a signal in step 3. The signal transmitted by the A-IoT UE can also be rewritten as information.

[0120] 1. Communication process of DT in Topology 1

[0121] Figure 8 This is a diagram showing the communication flow of DT in topology 1. Figure 8 This shows the signal flow between the base station and the A-IoT UE. Additionally, Figure 8 The communication flow shown is the DT communication flow. Therefore, although there is information transmission from the base station to the A-IoT UE, there is no information transmission from the A-IoT UE to the base station.

[0122] In the communication flow of DT in Topology 1, consider the following two steps.

[0123] • Step 1: The A-IoT UE is woken up by a signal such as the carrier waveform sent from the base station (Step 1 is not shown).

[0124] Step 2: The A-IoT UE receives information from the base station.

[0125] Additionally, in step 1, for example, if packets are generated at the application layer of the base station (equivalent to...), Figure 8 The “Packet arrival” shown in the image begins ( Figure 9 , Figure 10 and Figure 11 The same applies to step 1 as described in the text.

[0126] The A-IoT UE can also be woken up by signals transmitted from outside the base station (e.g., RF signals). Here, the signals transmitted from outside the base station can also correspond to the energy source that provides power to the A-IoT UE. The carrier waveform can also be rewritten as a carrier wave.

[0127] 2. Communication process of DO-DTT in Topology 1

[0128] Figure 9 This is a diagram illustrating the communication flow of DO-DTT in Topology 1. Figure 9 This shows the signal flow between the base station and the A-IoT UE. Additionally, Figure 9 The communication flow shown is the DO-DTT communication flow, therefore there is information transmission from the base station to the A-IoT UE and information transmission from the A-IoT UE to the base station.

[0129] In the DO-DTT communication process in Topology 1, consider the following three steps.

[0130] • Step 1: The A-IoT UE is woken up by a signal such as a carrier waveform sent from the base station (Step 1 is not shown).

[0131] Step 2: The A-IoT UE receives information from the base station.

[0132] Step 3: The A-IoT UE sends a signal to the base station.

[0133] 3. Communication process of DT in Topology 2

[0134] Figure 10 This is a diagram showing the communication flow of DT in topology 2. Figure 10This shows the signal flow between the base station, the int. UE, and the A-IoT UE. Additionally, Figure 10 The communication flow shown is the DT communication flow. Therefore, although there is information transmission to the A-IoT UE, there is no information transmission from the A-IoT UE.

[0135] In the communication process of DT in Topology 2, consider the following 4 steps.

[0136] • Step 0: int. The UE receives a trigger from the base station for sending a signal such as a carrier waveform to the A-IoT UE, and sends a signal to the A-IoT UE based on the trigger (Step 0 is not illustrated).

[0137] • Step 1: The A-IoT UE is woken up based on a signal such as the carrier waveform sent from int. UE (Step 1 is not illustrated).

[0138] Step 2: The A-IoT UE receives information from the base station via int.UE.

[0139] Step X: int. The UE sends a signal to the base station.

[0140] 4. Communication process of DO-DTT in Topology 2

[0141] Figure 11 This is a diagram illustrating the communication flow of DO-DTT in Topology 2. Figure 11 This shows the signal flow between the base station, the int. UE, and the A-IoT UE. Additionally, Figure 11 The communication flow shown is the DO-DTT communication flow, therefore there is information transmission to the A-IoT UE and information transmission from the A-IoT UE.

[0142] In the DO-DTT communication flow in Topology 2, imagine the following 5 steps of communication flow.

[0143] • Step 0: int. The UE receives a trigger from the base station for sending a signal such as a carrier waveform to the A-IoT UE, and sends a signal to the A-IoT UE based on the trigger (Step 0 is not illustrated).

[0144] • Step 1: The A-IoT UE is woken up based on a signal such as the carrier waveform sent from int. UE (Step 1 is not illustrated).

[0145] Step 2: The A-IoT UE receives information from the base station via int.UE.

[0146] Step 3: The A-IoT UE sends a signal to int.UE.

[0147] Step X: int. The UE sends a signal to the base station.

[0148] <Analysis>

[0149] Analysis 1

[0150] As described in the above <Communication Flow>, it is conceivable that the A-IoT UE will wake up in step 1 and receive information in step 2 in four communication flows (DT communication flow in topology 1, DO-DTT communication flow in topology 1, DT communication flow in topology 2, and DO-DTT communication flow in topology 2).

[0151] However, the A-IoT UE may not be able to properly receive information in step 2.

[0152] For example, if the A-IoT UE cannot identify the resources and modulation schemes through which the information it receives is transmitted, it may be unable to properly receive the information.

[0153] Therefore, in this disclosure, in Proposal 1, a technique is provided to enable an A-IoT UE to properly receive information.

[0154] Analysis 2

[0155] As described in the <Communication Flow> section above, it is conceivable that the A-IoT UE will wake up in step 1, receive information in step 2, and send signals (information) in two communication flows (DO-DTT communication flow in topology 1 and DO-DTT communication flow in topology 2).

[0156] However, if the A-IoT UE does not send an appropriate signal in step 3, the network, such as the base station / int. UE, may not be able to properly receive the A-IoT UE's signal.

[0157] For example, if the A-IoT UE does not send signals in the form of appropriate resources and modulation schemes, the network, such as the base station / int. UE, may not be able to receive the signals properly.

[0158] Therefore, in this disclosure, in Proposal 2, a technique is provided to enable an A-IoT UE to transmit appropriate signals.

[0159] Analysis 3

[0160] As explained in the <Communication Flow> section above, the presence or absence of the A-IoT UE's transmission process (step 3) depends on whether it is DT or DO-DTT.

[0161] However, the above-mentioned <Communication Flow> does not specify how the presence or absence of the A-IoT UE's transmission process is distinguished, and the A-IoT UE may not be able to properly determine whether or not to transmit signals.

[0162] For example, although an A-IoT UE follows a DO-DTT communication procedure, it may also perform an operation by receiving information (a DT communication procedure). Similarly, although an A-IoT UE follows a DT communication procedure, it may also perform a signal transmission operation (a DO-DTT communication procedure).

[0163] Therefore, in this disclosure, in Proposal 3, a technique is provided that can appropriately determine whether an A-IoT UE should transmit a signal.

[0164] Analysis 4

[0165] As described in the <Communication Flow> section above, it can be envisioned that the A-IoT UE is woken up in step 1 and receives information in step 2 in the four communication flows.

[0166] However, no specification is given for the size of the information received by the A-IoT UE in step 2, which may prevent the A-IoT UE from properly performing the information reception operation.

[0167] For example, an A-IoT UE may complete the information reception operation even if it has not finished receiving the information. Furthermore, an A-IoT UE may continue receiving information even after receiving the necessary information.

[0168] Therefore, in this disclosure, in Proposal 4, a technique is provided that enables an A-IoT UE to perform appropriate information receiving operations.

[0169] Analysis 5

[0170] As described in the <Communication Flow> section above, it can be envisioned that the A-IoT UE is woken up in step 1, receives information in step 2, and sends signals in step 3 in two communication flows.

[0171] However, since the size of the information sent by the A-IoT UE in step 3 is not specified, the A-IoT UE may not be able to properly perform the information sending operation.

[0172] For example, an A-IoT UE may complete the information transmission operation even if the transmission is incomplete. Furthermore, an A-IoT UE may continue transmitting information even after the necessary information has been sent.

[0173] Therefore, in this disclosure, in Proposal 5, a technique is provided that enables an A-IoT UE to perform appropriate information transmission operations.

[0174] <Proposal 1>

[0175] Proposal 1 proposes a technique for A-IoT UEs to properly receive information from a network such as a BS / int. UE. In Proposal 1, the process of A-IoT UEs receiving information is divided into two steps.

[0176] For example, step 2 in the four communication flows described above (the communication flow of DT in topology 1, the communication flow of DO-DTT in topology 1, the communication flow of DT in topology 2, and the communication flow of DO-DTT in topology 2) is divided into two sub-steps. Specifically, step 2 is divided into step 2A and step 2B as follows.

[0177] • Step 2A: The A-IoT UE receives information A, such as control information, from a network like the BS / int. UE.

[0178] • Step 2B: The A-IoT UE receives information B, such as data information, from a network like the BS / int. UE.

[0179] Figure 12 This is a diagram illustrating Proposal 1. Figure 12 The signal flow between the base station (gNB) and the A-IoT UE is shown (step 1 is not illustrated). Furthermore, in Figure 12 The diagram shows the signal flow direction of DT in topology 1.

[0180] Step 2 of receiving information from the base station is as follows: Figure 12 As shown, the process is divided into steps 2A and 2B. The A-IoT UE receives information A in step 2A and information B in step 2B.

[0181] Information A may also contain information for receiving information B. An A-IoT UE may also receive information B based on the information contained in information A. Information A may also be referred to as control information, and information B may also be referred to as data information.

[0182] In addition, Figure 12 The diagram illustrates an example where step 2 of the DT in Topology 1 is divided into two sub-steps (step 2A and step 2B). However, in the DO-DTT of Topology 1, step 2 of receiving information from the base station can also be divided into two sub-steps. Furthermore, in both the DT and DO-DTT of Topology 2, step 2 of receiving information from the UE is also divided into two sub-steps.

[0183] Information A may contain, for example, one or more of the information described in 1. to 7. below.

[0184] 1. Time-domain resources

[0185] Information A contains information about the time-domain resources of information B. Time-domain resources can be, for example, the starting time resource of information B / the quantity of time resources. The starting time resource can also be represented by time units such as time slots or symbols.

[0186] 2. Frequency domain resources

[0187] Information A contains information about the frequency domain resources of information B. Frequency domain resources can be, for example, the starting frequency resource of information B or the number of frequency resources. The starting frequency resource can also be represented by a frequency unit such as a subcarrier or a resource block.

[0188] 3. Code Domain Resources

[0189] Information A contains information about the code domain resources used (applied) in information B. Code domain resources could be, for example, the base sequence length / base sequence index / cyclic shift / orthogonal overlay code index used in information B. The base sequence can also be called the root sequence.

[0190] 4. Waveform / modulation scheme

[0191] Information A contains information about the waveform / modulation scheme used in information B. The waveform / modulation scheme can be, for example, any of ASK (OOK), FSK, PSK, or OFDM.

[0192] Additionally, ASK stands for Amplitude Shift Keying. OOK stands for On-Off Keying. FSK stands for Frequency Shift Keying. PSK stands for Phase Shift Keying. OFDM stands for Orthogonal Frequency-Division Multiplexing.

[0193] If the waveform / modulation scheme of information B uses ASK (OOK), information A can also contain information representing any of the following four candidate (modes). The following four modes define how states (or information) such as 1 or 0 are represented in ASK (OOK).

[0194] ·ASK / OOK-1

[0195] In ASK / OOK-1, a single bit is represented in a time unit such as 1 symbol or 1 slot. For example, 1 and 0 in OOK are shown below.

[0196] OOK=1: All subcarriers are modulated

[0197] OOK=0: The power of all subcarriers is set to 0.

[0198] ·ASK / OOK-2

[0199] In ASK / OOK-2, the states of 0 and 1 are represented in the parallel M-bit OOK in the frequency domain. For example, a frequency unit such as a subcarrier is divided into M segments, and the 1 and 0 in the OOK are shown below.

[0200] OOK=1: All subcarriers within the segment are modulated.

[0201] OOK=0: The power of all subcarriers within the segment is set to 0.

[0202] ·ASK / OOK-3

[0203] In ASK / OOK-3, the states of 0 and 1 are shown in Multi-tone Single-bit OOK. For example, a frequency unit such as a subcarrier is divided into L segments, and the 1 and 0 in OOK are shown below.

[0204] OOK=1: One subcarrier in each segment is modulated, and the power of the remaining subcarriers is set to 0.

[0205] OOK=0: The power of all subcarriers in all segments is set to 0.

[0206] ·ASK / OOK-4

[0207] In ASK / OOK-4, the M-bit OOK transform in the time domain represents the states of 0 and 1. For example, OOK is generated through a transform such as DFT / least squares. To approximate the time-domain OOK signal, an OFDM-based waveform is used. To make the OFDM-modulated time-domain signal approximate the OOK signal, a set of frequency-domain signals is determined.

[0208] When the waveform / modulation scheme of information B uses FSK, information A can also contain information representing either of the following two candidate (modes). The following two modes illustrate how a state (or information) such as 1 or 0 is represented in FSK.

[0209] ·FSK-1

[0210] In FSK-1, frequency units such as subcarriers are divided into M pairs of segments. In each pair of segments, one segment is modulated, and the power of the other segment is set to 0.

[0211] ·FSK-2

[0212] In FSK-2, frequency units such as subcarriers are divided into 2^M segments. One of the 2^M segments is modulated, and the power of the remaining segments is set to 0.

[0213] 5. Encoding Scheme

[0214] Information A contains information about the encoding scheme used in information B. The encoding scheme could be, for example, the following encoding scheme.

[0215] • PIE (Pulse Interval Encoding)

[0216] In PIE, it is indicated as 0 or 1 based on amplitude, power, frequency, or the time when a phase reversal is detected.

[0217] Figure 13A and Figure 13B This is a diagram illustrating PIE. Figure 13A and Figure 13B The vertical axis represents amplitude. The horizontal axis represents time. Alternatively, the vertical axis can also represent power, frequency, or phase.

[0218] Data 0 and 1 are represented, for example, based on the following content.

[0219] data=0: The amplitude remains at k during the time duration X1, and then reverses to l after the time duration X1.

[0220] data=1: The amplitude remains at k during the period X2 (X2>X1), and reverses to l after the period X2.

[0221] The definitions of data=0 and data=1 can also be replaced. For example, the data 0 and 1 can also be represented based on the following.

[0222] data=0: The amplitude remains at k during the period X2, and then reverses to l after the period X2.

[0223] data=1: The amplitude remains at k during period X1, and reverses to l after period X1.

[0224] FM0 (frequency modulation)

[0225] In FM0, amplitude, power, frequency, or phase is inverted at time unit boundaries such as symbols or time slots. Furthermore, in FM0, when the data is 0, for example at the center of a time unit, amplitude, power, frequency, or phase is inverted. Conversely, in FM0, when the data is 1, for example at the center of a time unit, amplitude, power, frequency, or phase is not inverted.

[0226] Figure 14A and Figure 14B This is a graph illustrating data 0 of FM0. Figure 14A and Figure 14B The vertical axis represents amplitude. The horizontal axis represents time. Alternatively, the vertical axis can also represent power, frequency, or phase.

[0233] data=0: At the boundaries of time units such as symbols or time slots, the amplitude is reversed, and at the center of the time unit, the amplitude is not reversed.

[0234] data=1: The amplitude is reversed at the boundaries of time units such as symbols or time slots, and at the center of the time unit, the amplitude is reversed.

[0235] Miller coding

[0236] In Miller coding, when the data is 0, for example, at the center of a time unit such as a symbol or time slot, the amplitude, power, frequency, or phase is not inverted; when the data is 1, the amplitude, power, frequency, or phase is inverted at the center of the time unit. Furthermore, in Miller coding, at the boundaries of a time unit such as a symbol or time slot, the amplitude, power, frequency, or phase is not inverted.

[0237] Figure 16A and Figure 16B This is a diagram illustrating the Miller-coded data 0. Figure 16A and Figure 16B The vertical axis represents amplitude. The horizontal axis represents time. Alternatively, the vertical axis can also represent power, frequency, or phase.

[0238] Data 0 is shown, for example, based on the following content.

[0239] data=0: At the center of a time unit such as a symbol or time slot, the amplitude is not reversed. Furthermore, if data remains 0, the amplitude is reversed at the boundaries of the time unit.

[0240] Figure 17 This is a diagram illustrating data 1 of Miller encoding. Figure 17 The vertical axis represents amplitude. The horizontal axis represents time. Alternatively, the vertical axis can also represent power, frequency, or phase.

[0241] Data 1 is shown, for example, based on the following content.

[0242] data=1: The amplitude is reversed at the center of a time unit such as a symbol or time slot.

[0243] The definitions of data=0 and data=1 can also be replaced. For example, data 0 and 1 can also be represented based on the following.

[0244] data=0: The amplitude is reversed at the center of a time unit such as a symbol or time slot.

[0245] data=1: At the center of a time unit such as a symbol or time slot, the amplitude is not reversed. Furthermore, if data remains 1, the amplitude is reversed at the boundaries of the time unit.

[0246] Manchester encoding

[0247] In Manchester encoding, the amplitude, power, frequency, or phase is inverted at the center of a time unit such as a symbol or slot. Furthermore, in Manchester encoding, the amplitude, power, frequency, or phase is inverted between two data 0s, and between two data 1s.

[0248] Figure 18A and Figure 18BThis is a diagram illustrating Manchester encoding. Figure 18A and Figure 18B The vertical axis represents amplitude. The horizontal axis represents time. Alternatively, the vertical axis can also represent power, frequency, or phase.

[0249] Data 0 and 1 are shown, for example, based on the following content.

[0250] data=0: At the center of a time unit such as a symbol or time slot, the amplitude is reversed from l to k (k>l).

[0251] data=1: At the center of a time unit such as a symbol or time slot, the amplitude is reversed from k to l.

[0252] The definitions of data=0 and data=1 can also be replaced. For example, data 0 and 1 can also be represented based on the following.

[0253] data=0: At the center of a time unit such as a symbol or time slot, the amplitude is reversed from k to l.

[0254] data=1: At the center of a time unit such as a symbol or time slot, the amplitude is reversed from l to k.

[0255] 6. Association information of the target A-IoT UE

[0256] Information A contains information about the A-IoT UE (target A-IoT UE) that receives Information A. This information can also be understood as the destination information of Information A. A network such as a BS / int. UE sends (notifies) Information A to all or some of its subordinate A-IoT UEs based on the destination information contained in Information A. An A-IoT UE receives Information A based on the destination information of the A-IoT UEs receiving Information A contained in Information A.

[0257] Information A contains information about the target A-IoT UE that receives Information B. This information can also be understood as the destination information of Information B. A network such as a BS / int. UE sends (notifies) Information B to all or some of its subordinate A-IoT UEs based on the destination information contained in Information A. An A-IoT UE receives Information B based on the destination information of the A-IoT UE receiving Information B contained in Information A.

[0258] Destination information can be either a specific ID (identifier) ​​of the A-IoT UE or an ID notified from the network.

[0259] The ID notified from the network can be static or dynamic. For example, the ID notified from the network can be notified in higher-level signaling such as RRC, or in initial access such as random access. The ID notified from the network can be an ID identified within a group such as a cell unit, an ID identified in individual A-IoT UEs, or an ID identified in a UE group that bundles multiple A-IoT UEs. Information A can also be scrambled using destination information such as the ID.

[0260] 7. Content / Format of Information B

[0261] Message A contains information indicating what content will be sent in Message B / information about the format of Message B.

[0262] The format of information B may include, for example, its time / frequency resources / coding scheme / waveform. The format of information B (time / frequency resources / coding scheme / waveform, etc.) is predefined by multiple specifications / set from the NW, with one format specified in information A. The A-IoT UE uses the format specified in information A to receive information B.

[0263] <Proposal 1: Change 1>

[0264] The information used to receive information B (the information described in sections 1 to 7 above) can be predefined in the specification or pre-configured in configuration information sent from a network such as the BS / int. UE. Alternatively, the configuration information can be different from information A and can be notified in higher-level signaling such as RRC.

[0265] The information used to receive information B can also be categorized as: information indicated in information A, information predefined in the specification, and information predefined in the setting information. In other words, the information used to receive information B can also be partly indicated in information A, partly predefined in the specification, and partly predefined in the setting information.

[0266] <Proposal 1: Change 2>

[0267] The information used to receive information A can be predefined in the specification or predefined in the configuration information sent from a network such as the BS / int. UE. The information used to receive information A can also be the information described in sections 1 to 7 above.

[0268] The information used to receive information A can also be divided into information predefined in the specification and information predefined in the setting information. In other words, the information used to receive information A can also be partly predefined in the specification and partly predefined in the setting information.

[0269] <Proposal 1: Change 3>

[0270] Multiple candidates for receiving information A / information B can be predefined in the specification or pre-configured in setting information sent from a network such as a BS / int. UE. The A-IoT UE can also perform blind decoding on the predefined / pre-configured candidates to receive information A / information B.

[0271] <Proposal 1: Change 4>

[0272] One piece of information A can also be applied to only one piece of information B.

[0273] When multiple pieces of information B follow one piece of information A, one piece of information A can be applied to the subsequent multiple pieces of information B. Alternatively, a portion of the information contained in information A can be applied to one piece of information B, or a portion of the information contained in information A can be applied to multiple pieces of information B.

[0274] <Proposal 1: Change 5>

[0275] A-IoT UEs can also report the supported information (described in sections 1 to 7 above) as capabilities to networks such as BS / int. UEs.

[0276] <Proposal 1: Change 6>

[0277] Information A and information B can be notified to the A-IoT UE using either the same physical layer channel or different physical layer channels.

[0278] <Proposal 1: Change 7>

[0279] Step 2 may also consist of receiving only information B (data information). In other words, receiving information A (control information) may be omitted. All or part of the information used to receive information B (the information described in 1.~7. above) may be predefined in the specification or predefined in the setting information.

[0280] <Proposal 1: Change 8>

[0281] Information A and information B can also be sent in the same time / frequency resource without separation.

[0282] The resource information for information A and information B within a single time / frequency resource can be predefined in the specification or pre-defined in the configuration information. For example, information about which part of a time / frequency resource belongs to information A and which part belongs to information B can be predefined or pre-defined.

[0283] The resource information of information A / information B within a single time / frequency resource can be represented, for example, using the number of symbols or time slots starting from the beginning of the time / frequency resource. For instance, the resource of information A can be represented as the starting symbols X to Y of a single time / frequency resource, and the resource of information B can be the remaining resources. The A-IoT UE can also buffer the entire information (the entire time / frequency resource), decode information A based on its resource information, and then decode information B after decoding information A.

[0284] <Proposal 1: Summary>

[0285] The A-IoT UE receives information B based on information A sent from a network such as a BS / int. UE. According to this operation, the A-IoT UE is able to appropriately receive information from the network such as the BS / int. UE.

[0286] <Proposal 2>

[0287] Proposal 2 proposes a technology for A-IoT UEs to send appropriate signals to networks such as BS / int. UEs. Proposal 2 proposes the following options 1 and 2.

[0288] <Proposal 2: Option 1>

[0289] Proposal 2: In Option 1, the information received by the A-IoT UE from a network such as a BS / int. UE includes information about the signals sent by the A-IoT UE to the network such as the BS / int. UE. The A-IoT UE sends signals to the network such as the BS / int. UE based on the information received from the network.

[0290] For example, as described in the <Communication Flow> above, the A-IoT UE receives information in step 2 of the DO-DTT communication flow in Topology 1, and sends a signal to the base station in step 3. The A-IoT UE sends a signal to the base station based on the information received in step 2 (step 3).

[0291] Furthermore, as described in the <Communication Flow> section above, the A-IoT UE receives information in step 2 of the DO-DTT communication flow in Topology 2, and sends a signal to the int. UE in step 3. The A-IoT UE sends a signal to the int. UE based on the information received in step 2.

[0292] Figure 19 This is a diagram illustrating Proposal 2: Option 1. Figure 19The signal flow between the base station (gNB) and the A-IoT UE is shown (step 1 is not illustrated). Furthermore, in Figure 19 The diagram shows the signal flow direction of DO-DTT in topology 1.

[0293] like Figure 19 As shown, in the DO-DTT of topology 1, the A-IoT UE receives information from the base station (step 2). Based on the information received from the base station, the A-IoT UE sends a signal to the base station (step 3).

[0294] In addition, Figure 19 The signal transmission of DO-DTT in Topology 1 has been described, but in the same way in DO-DTT in Topology 2, the A-IoT UE sends a signal to int. UE in step 2 based on the information received from int. UE (step 3).

[0295] In addition, the A-IoT UE sends signals to a network such as the BS / int. UE based on information A / information B as described in Proposal 1.

[0296] The information received in step 2 includes one or more of the information in 1 to 8 below.

[0297] 1. Time-domain resources

[0298] The information received in step 2 includes information about the frequency domain resources of the signal transmitted in step 3. Time domain resources can also be, for example, the start time resources / number of time resources for the signal transmitted in step 3. The start time resources / number of time resources can also be represented by time units such as time slots or symbols.

[0299] 2. Frequency domain resources

[0300] The information received in step 2 includes information about the frequency domain resources of the signal transmitted in step 3. Frequency domain resources can be, for example, the starting frequency resources / number of frequency resources of the signal transmitted in step 3. The starting frequency resources / number of frequency resources can also be represented by frequency units such as subcarriers or resource blocks.

[0301] 3. Code Domain Resources

[0302] The information received in step 2 includes information about the code domain resources used (applied) in the signal transmitted in step 3. Code domain resources could be, for example, the reference sequence length / reference sequence index / cyclic shift / orthogonal overlay code index used in the signal transmitted in step 3.

[0303] 4. Waveform / Modulation Scheme

[0304] The information received in step 2 includes information about the waveform / modulation scheme used in the signal transmitted in step 3. The waveform / modulation scheme can be, for example, any of ASK (OOK), FSK, PSK, or OFDM.

[0305] If the waveform / modulation scheme of the signal transmitted in step 3 uses ASK (OOK), it means that information about any of the four candidates described in "4. Waveform / Modulation Scheme" of <Proposal 1> can also be included in the information received in step 2.

[0306] 5. Encoding Scheme

[0307] The information received in step 2 includes information about the encoding scheme used in the signal transmitted in step 3. The encoding scheme may also be as described in "5. Encoding Scheme" of Proposal 1.

[0308] 6. Association information of the target A-IoT UE

[0309] The information received in step 2 includes information about the A-IoT UE (target A-IoT UE) that received the information in step 2. This information can also be understood as destination information for the information in step 2. A network such as a BS / int. UE, based on the destination information contained in the information in step 2, may, for example, send (notify) the information in step 2 to all or some of its subordinate A-IoT UEs.

[0310] Destination information can be either a specific ID of the A-IoT UE or an ID notified from the network.

[0311] The ID notified from the network can be static or dynamic. For example, the ID can be notified in higher-level signaling such as RRC, or during initial access such as random access. The ID notified from the network can be an ID identified within a group such as a cell unit, an ID identified in individual A-IoT UEs, or an ID identified in a UE group that bundles multiple A-IoT UEs. The information received in step 2 can also be scrambled using destination information such as the ID.

[0312] The information received in step 2 includes information about the target A-IoT UE that sent the signal in step 3. For example, the information received in step 2 may also include the specific ID of the A-IoT UE that sent the signal in step 3, or the ID that was notified to the A-IoT UE from the network.

[0313] 7. The content / format of the signal in step 3

[0314] The information received in step 2 includes information indicating what content is sent in the signal sent in step 3 / information about the format of the signal in step 3.

[0315] The format of the signal in step 3 includes, for example, the time / frequency resources / coding scheme / waveform of the signal in step 3. The format of the signal in step 3 (time / frequency resources / coding scheme / waveform, etc.) is pre-defined by multiple specifications / set from the NW, with one format specified in the information received in step 2. The A-IoT UE uses the format specified by the information received in step 2 to transmit the signal in step 3.

[0316] 8. Transmission power of the signal in step 3

[0317] The information received in step 2 includes information about the transmission power of the signal sent in step 3. Based on the transmission power information included in the information received in step 2, the A-IoT UE controls the transmission power of the signal sent in step 3.

[0318] <Proposal 2: Option 2>

[0319] Proposal 2: In Option 2, step 3, where the A-IoT UE sends a signal to a network such as a BS / int. UE, is divided into two sub-steps. For example, step 3 is divided into step 3A and step 3B as follows.

[0320] • Step 3A: The A-IoT UE sends a signal A, such as control information, to the network such as the BS / int.UE.

[0321] Step 3B: The A-IoT UE sends a signal B, such as data information, to the network such as the BS / int. UE.

[0322] Figure 20 This is a diagram illustrating Proposal 2: Option 2. Figure 20 The signal flow between the base station (gNB) and the A-IoT UE is shown (step 1 is not illustrated). Furthermore, in Figure 20 The diagram shows the signal flow direction of DO-DTT in topology 1.

[0323] like Figure 20 As shown, step 3, which involves sending a signal to the base station, is divided into steps 3A and 3B. In step 3A, the A-IoT UE sends signal A to the base station, and in step 3B, it sends signal B.

[0324] Signal A may also contain information related to signal B, which is sent to the base station. The base station receives signal B based on the information contained in signal A. Signal A may also be referred to as control information, and signal B may also be referred to as data information.

[0325] Information related to signal B can also be the information described in sections 1 to 8 of <Proposal 2: Option 1>. For example, the A-IoT UE can also apply one or more pieces of information described in sections 1 to 8 of <Proposal 2: Option 1> to signal B sent to the base station, and send information applied to signal B to the base station via signal A as information related to signal B.

[0326] In addition, Figure 20 The signal transmission of DO-DTT in Topology 1 was described, but in the same way in DO-DTT in Topology 2, the A-IoT UE divides step 3 into two steps, step 3A and step 3B, and sends signal A and signal B to int. UE.

[0327] <Proposal 2: Change 1>

[0328] The information used in signal B (e.g., the information described in sections 1 to 8 of proposal 2) can be indicated by the information in step 2 / step 2A / step 2B, or it can be predefined in the specification or pre-set in the configuration information sent from a network such as BS / int. UE.

[0329] The information used in signal B can also be categorized as: information indicated in step 2 / step 2A / step 2B, information predefined in the specification, and information predefined in the setting information. In other words, the information used in signal B can also be partly indicated in step 2 / step 2A / step 2B, partly predefined in the specification, and partly predefined in the setting information. Furthermore, the information used in signal B can also be sent to the network in signal A.

[0330] <Proposal 2: Change 2>

[0331] The information used in signal A (e.g., the information described in 1.~8. of proposal 2) can be indicated by the information in step 2 / step 2A / step 2B, or it can be predefined in the specification, or it can be pre-set in the configuration information sent from a network such as BS / int. UE.

[0332] The information used in signal A can also be categorized as follows: information indicated in step 2 / step 2A / step 2B, information predefined in the specification, and information predefined in the setting information. In other words, the information used in signal A can also be partly indicated in step 2 / step 2A / step 2B, partly predefined in the specification, and partly predefined in the setting information.

[0333] <Proposal 2: Change 3>

[0334] Multiple candidates for transmitting signal A / signal B can be predefined in the specification or indicated from a network such as a BS / int. UE. An A-IoT UE can also select one of these candidates to transmit signal A / signal B. A network such as a BS / int. UE can also blindly decode multiple candidates to receive signal A / signal B.

[0335] <Proposal 2: Change 4>

[0336] One piece of information in step 2 can also be applied to one or more of the multiple signals in step 3. For example, one piece of information in step 2 can also be applied to one or both of signal A and signal B in step 3. Alternatively, a portion of one piece of information in step 2 can be applied to one of the multiple signals in step 3, or a portion of one piece of information in step 2 can be applied to multiple signals in step 3.

[0337] <Proposal 2: Change 5>

[0338] A signal A can also be applied to only one signal B.

[0339] When multiple signals B follow one signal A, one signal A can also be applied to the subsequent multiple signals B. Alternatively, a portion of the information contained in signal A can be applied to one signal B, or a portion of the information contained in signal A can be applied to multiple signals B.

[0340] <Proposal 2: Change 6>

[0341] A-IoT UEs can also report the supported information (described in sections 1 to 8 of Proposal 2: Option 1) as a capability to networks such as BS / int. UEs.

[0342] <Proposal 2: Change 7>

[0343] Signal A and signal B can be sent to a network like BS / int. UE using the same physical layer channel, or they can be sent to a network like BS / int. UE using different physical layer channels.

[0344] <Proposal 2: Change 8>

[0345] Signal A and signal B can also be transmitted in a single time / frequency resource without separation.

[0346] Resource information for signal A and signal B within a time / frequency resource can be predefined in the specification or pre-set in the configuration information. For example, information about which part of a time / frequency resource belongs to signal A and which part belongs to signal B can be either predefined or pre-set.

[0347] Resource information for signal A / signal B within a single time / frequency resource can be represented, for example, by the number of symbols or time slots starting from the beginning of the time / frequency resource. For instance, the resource of signal A can be represented as the starting symbols X to Y of a single time / frequency resource, and the resource of signal B can be the remaining resources. A network like a BS / int. UE can also buffer the entire signal (the entire time / frequency resource), decode signal A based on its resource information, and then decode signal B after decoding signal A.

[0348] <Proposal 2: Change 9>

[0349] The information A / information B received in step 2A / step 2B may also contain one or more pieces of information from proposal 2, from 1 to 8.

[0350] <Proposal 2: Summary>

[0351] The A-IoT UE transmits signals to the network (such as the BS / int. UE) based on information received from the network. According to this operation, the A-IoT UE is able to send appropriate signals to the network.

[0352] <Proposal 3>

[0353] In Proposal 3, a technique is proposed for the A-IoT UE to appropriately determine the presence or absence of a signal transmission procedure (step 3).

[0354] The A-IoT UE determines whether or not a transmission procedure is required based on one or more of the following 1.~8. (determining whether to execute the DT communication procedure or the DO-DTT communication procedure).

[0355] 1. Receiving information

[0356] The A-IoT UE determines whether or not to initiate a transmission process based on information received from a network such as a BS / int. UE. For example, the A-IoT UE determines whether or not to initiate a transmission process based on (a) or (b) below.

[0357] (a) Information used for DT

[0358] If the A-IoT UE receives information for DT (e.g., information related to DT services) in step 2 / step 2A / step 2B, it determines that there is no transmission process. Additionally, if the A-IoT UE receives information for DT in step 2, it can also determine that there is no subsequent information to receive (e.g., information B from step 2B).

[0359] (b) Information for DO-DTT

[0360] If the A-IoT UE receives information for DO-DTT (e.g., information related to DO-DTT services) in step 2 / step 2A / step 2B, it determines that there is a transmission process.

[0361] 2. Time-domain resources

[0362] The A-IoT UE determines whether or not to initiate a transmission process based on the temporal resources of the information received from the network such as the BS / int. UE. For example, the A-IoT UE determines whether or not to initiate a transmission process based on the size / location of the temporal resources of the information received in step 2 / step 2A / step 2B.

[0363] 3. Frequency domain resources

[0364] The A-IoT UE determines whether or not to initiate a transmission process based on the frequency domain resources of the information received from the network such as the BS / int. UE. For example, the A-IoT UE determines whether or not to initiate a transmission process based on the size / location of the frequency domain resources of the information received in step 2 / step 2A / step 2B.

[0365] 4. Code Domain Resources

[0366] The A-IoT UE determines whether or not to initiate a transmission process based on the code domain resources used in the information received from a network such as a BS / int. UE. For example, the A-IoT UE determines whether or not to initiate a transmission process based on the code domain resources used in the information received in step 2 / step 2A / step 2B.

[0367] 5. Instructions

[0368] The A-IoT UE determines whether or not a transmission process exists based on indications contained in information received from a network such as a BS / int. UE. For example, the A-IoT UE determines whether or not a transmission process exists based on indications contained in information received in step 2 / step 2A / step 2B.

[0369] 6. Scrambling ID

[0370] The A-IoT UE determines whether or not a transmission process is required based on the scrambling ID used in the information received from a network such as a BS / int. UE. For example, the A-IoT UE determines whether or not a transmission process is required based on the scrambling ID used in the information received in step 2 / step 2A / step 2B. Alternatively, the scrambling ID can also be the ID described in the "Association Information of the Target A-IoT UE" section of Proposal 1.

[0371] 7. Carrier in Step 1

[0372] The A-IoT UE determines whether or not to include a transmission process based on the carrier in step 1. For example, the A-IoT UE determines whether or not to include a transmission process based on the waveform, time domain resources, frequency domain resources, code domain resources, signal duration, and phase switching of the carrier in step 1.

[0373] 8. Size of received information

[0374] The A-IoT UE determines whether or not to initiate a transmission process based on the size of the information received from the network such as the BS / int. UE. For example, the A-IoT UE determines whether or not to initiate a transmission process based on the total payload size of the information received in step 2 / step 2A / step 2B.

[0375] <Proposal 3: Changes>

[0376] A-IoT UEs may also support either DT or DO-DTT. When an A-IoT UE is woken up by a carrier waveform, it performs the operation of the supported DT or DO-DTT.

[0377] <Proposal 3: Summary>

[0378] The A-IoT UE determines whether or not to transmit a signal to the network such as the BS / int. UE based on information sent from the network. According to this operation, the A-IoT UE can appropriately determine whether the signal transmission process (step 3) is required.

[0379] <Proposal 4>

[0380] The A-IoT UE receives information in DT and DO-DTT (step 2 / step 2A / step 2B). Proposal 4 provides techniques for the appropriate information reception operations performed by the A-IoT UE.

[0381] The size of the information received by the A-IoT UE is determined according to the following options 1 to 5. The size of the information received by the A-IoT UE is the size of the information received in step 2 / step 2A / step 2B, for example, the size / payload length indicated by bits.

[0382] <Proposal 4: Option 1>

[0383] The size of the information received by the A-IoT UE is a fixed value, defined in the specification. The maximum / minimum size of the information received by the A-IoT UE can also be defined in the specification.

[0384] <Proposal 4: Option 2>

[0385] The size of the information received by the A-IoT UE can also be notified from the network such as the BS / int. UE.

[0386] For example, the size of the information received by the A-IoT UE is notified by information prior to the information received in step 2 / step 2A / step 2B. For example, the size of the information received by the A-IoT UE is notified by RRC / MAC CE / DCI.

[0387] <Proposal 4: Option 3>

[0388] The size of the information received by the A-IoT UE is limited to multiple candidates. For example, the size of the information received by the A-IoT UE is limited to three candidates: X bits, Y bits, and Z bits. One of the multiple candidates is notified to the A-IoT UE from the network such as the BS / int. UE.

[0389] <Proposal 4: Option 4>

[0390] The size of the information received by the A-IoT UE is implicitly indicated from the network such as the BS / int. UE. For example, the size of the information received by the A-IoT UE is associated with parameters notified from the network such as the BS / int. UE. The number of parameters associated with the size of the information can be one or more.

[0391] The parameters associated with the size of the information can also be, for example, time-domain resources, frequency-domain resources, waveforms, modulation schemes, or coding schemes. For instance, the number of bits of information received by an A-IoT UE can also be calculated based on the size of the time-domain resources / frequency-domain resources.

[0392] The size of the information can be associated with parameters such as the type / format of the information. Different types / formats can also be associated with different fixed bit counts. The type / format can also be notified from a network such as the BS / INT.UE. The type of information can also indicate whether it is control information or data information.

[0393] <Proposal 4: Option 5>

[0394] The size of the information received by the A-IoT UE is limited to multiple candidates. For example, the size of the information received by the A-IoT UE is limited to three candidates: X bits, Y bits, and Z bits. The A-IoT UE uses multiple candidates to perform blind decoding of the received information. These multiple candidates can be notified from the network, such as the BS / int. UE, or defined in the specification.

[0395] <Proposal 4: Change 1>

[0396] A-IoT UEs can also report the size / maximum / minimum values ​​of the information they can receive as capabilities to networks such as BS / int.UE.

[0397] <Proposal 4: Change 2>

[0398] The A-IoT UE can also support multiple options in Proposal 4. The A-IoT UE can also change the application options based on the type of information received.

[0399] For example, the size / maximum / minimum value of the information A received in step 2A can be fixed, variable, or semi-static.

[0400] For example, the size / maximum / minimum value of the information B received in step 2B can also be variable and dynamic.

[0401] For example, considering use cases like commands, the size / maximum / minimum value of the information B received in step 2B can also be variable and semi-static. Additionally, in A-IoT, it is envisioned that the packet size from a network such as a BS / int.UE is somewhat deterministic.

[0402] <Proposal 4: Change 3>

[0403] The size, maximum value, and minimum value of information that an A-IoT UE can receive can also vary depending on whether the received information is information A or information B.

[0404] <Proposal 4: Summary>

[0405] The size of the information received by the A-IoT UE is predefined / notified to the A-IoT UE from the BS / int. Based on this structure, the A-IoT UE can perform appropriate information reception operations. For example, the A-IoT UE can perform appropriate information reception operations simply by receiving information of a predefined / notified size.

[0406] <Proposal 5>

[0407] The A-IoT UE transmits signals in DO-DTT (step 3 / step 3A / step 3B). Proposal 5 provides techniques for the appropriate transmission operations of signals performed by the A-IoT UE.

[0408] The magnitude of the signal transmitted by the A-IoT UE is determined according to options 1 to 5 below. The magnitude of the signal transmitted by the A-IoT UE is the magnitude of the signal transmitted in step 3 / step 3A / step 3B, for example, represented in bits.

[0409] <Proposal 5: Option 1>

[0410] The magnitude of the signal transmitted by the A-IoT UE is a fixed value, defined in the specification. The maximum / minimum magnitude of the signal transmitted by the A-IoT UE can also be defined in the specification.

[0411] <Proposal 5: Option 2>

[0412] The magnitude of the signal transmitted by the A-IoT UE is notified from a network such as the BS / int. UE, or reported by the A-IoT UE to a network such as the BS / int. UE.

[0413] For example, the magnitude of the signal transmitted by the A-IoT UE is notified by information received by the A-IoT UE before the signal is transmitted in step 3 / step 3A / step 3B. For example, the magnitude of the signal transmitted by the A-IoT UE is notified via RRC / MAC CE / DCI.

[0414] For example, the magnitude of signal B transmitted by the A-IoT UE is notified by information transmitted by the A-IoT UE prior to the transmission of the signal in step 3 / step 3A / step 3B. For example, the magnitude of the signal transmitted by the A-IoT UE is reported via RRC / MAC CE / DCI.

[0415] <Proposal 5: Option 3>

[0416] The size of the signal transmitted by the A-IoT UE is limited to multiple candidates. For example, the size of the signal transmitted by the A-IoT UE is limited to three candidates: X bits, Y bits, and Z bits. One of the multiple candidates is notified to the A-IoT UE from a network such as a BS / int. UE. Alternatively, one of the multiple candidates is reported by the A-IoT UE to a network such as a BS / int. UE.

[0417] <Proposal 5: Option 4>

[0418] The magnitude of the signal transmitted by the A-IoT UE is implicitly indicated by the network such as the BS / int. UE, or implicitly reported by the A-IoT UE to the network such as the BS / int. UE.

[0419] For example, the magnitude of a signal transmitted by an A-IoT UE is associated with parameters notified from a network such as a BS / int. UE. The magnitude of a signal transmitted by an A-IoT UE is also associated with parameters reported by the A-IoT UE to a network such as a BS / int. UE. The number of parameters associated with the signal magnitude can be one or more.

[0420] The parameters associated with the signal size can be, for example, time-domain resources, frequency-domain resources, waveform, modulation scheme, or coding scheme. For instance, the number of bits in a signal transmitted by an A-IoT UE can also be calculated based on the size of the time-domain resources / frequency-domain resources.

[0421] The parameter associated with the signal magnitude can also be, for example, the signal type / format. Each type / format can also be associated with a fixed number of bits. The type / format can be notified from a network such as the BS / int. UE, or reported by the A-IoT UE to the network such as the BS / int. UE.

[0422] <Proposal 5: Option 5>

[0423] The size of the signal transmitted by the A-IoT UE is limited to multiple candidates. For example, the size of the signal transmitted by the A-IoT UE is limited to three candidates: X bits, Y bits, and Z bits.

[0424] The A-IoT UE selects one of several candidates. Networks like the BS / int. UE use these multiple candidates for blind decoding of the received signal. The multiple candidates are either notified from the BS / int. UE or reported to the BS / int. UE by the A-IoT UE. The multiple candidates can also be defined in the specification document.

[0425] <Proposal 5: Change 1>

[0426] A-IoT UEs can also report the size / maximum / minimum value of the signals they can transmit as capabilities to networks such as BS / int.UE.

[0427] <Proposal 5: Change 2>

[0428] The A-IoT UE can also support multiple options in Proposal 5. The A-IoT UE can also change the application options based on the type of signal transmitted.

[0429] For example, the magnitude / maximum / minimum value of the signal A sent in step 3A can be fixed, variable, or semi-static.

[0430] For example, the size / maximum / minimum value of the signal B sent in step 3B can also be variable and dynamic.

[0431] For example, considering use cases such as inventory, the size / maximum / minimum value of signal B sent in step 3B can also be variable and semi-static. Additionally, in A-IoT, it is envisioned that the packet size sent to a network such as BS / int.UE is determined to some extent.

[0432] <Proposal 5: Change 3>

[0433] The size, maximum value, and minimum value of the signal that an A-IoT UE can send can also vary depending on whether the signal being sent is signal A or signal B.

[0434] <Proposal 5: Summary>

[0435] The size of the information transmitted by the A-IoT UE is predefined / notified to the A-IoT UE from the network such as the BS / int. UE / reported to the network such as the BS / int. UE. Based on this structure, the A-IoT UE can perform appropriate signal transmission operations. For example, the A-IoT UE only needs to transmit a signal of a predefined / notified size to perform the appropriate signal transmission operation.

[0436] <Base station structure>

[0437] Figure 21 This is a block diagram illustrating an example of the structure of a base station 10 according to an embodiment. Base station 10 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. Base station 10 and device 20 (see reference) Figure 22 Communication is conducted wirelessly. Base station 10 can also be an intermediate node, an auxiliary node, or a terminal (the terminal of SL that communicates with device 20).

[0438] Transmitting unit 101 sends downlink (DL) signals to device 20. For example, transmitting unit 101 transmits DL signals under the control of control unit 103.

[0439] The DL signal may also include, for example, downlink data signals and control information (e.g., Downlink Control Information (DCI)). Furthermore, the DL signal may also include scheduling information relating to signal transmission of device 20 (e.g., UL authorization). Additionally, the DL signal may include higher-layer control information (e.g., Radio Resource Control (RRC) control information). Furthermore, the DL signal may also include reference signals.

[0440] The channels used in transmitting DL signals may include data channels and control channels. For example, the data channel may include PDSCH (Physical Downlink Shared Channel), and the control channel may include PDCCH (Physical Downlink Control Channel). For instance, base station 10 uses PDCCH to transmit control information to device 20 and uses PDSCH to transmit downlink data signals.

[0441] The reference signals included in the DL signal may also include at least one of the following: Demodulation Reference Signal (DMRS), Phase Tracking Reference Signal (PTRS), Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and Positioning Reference Signal (PRS) for location information. For example, reference signals such as DMRS and PTRS are used for demodulation of downlink data signals and are transmitted using PDSCH.

[0442] The receiving unit 102 receives uplink (UL) signals transmitted from the device 20. For example, the receiving unit 102 receives UL signals under the control of the control unit 103.

[0443] The control unit 103 can also control the communication operations of the base station 10, including the transmission processing of the transmission unit 101 and the reception processing of the reception unit 102.

[0444] For example, the control unit 103 acquires data and control information from higher layers and outputs it to the transmitting unit 101. Furthermore, the control unit 103 outputs data and control information received from the receiving unit 102 to higher layers.

[0445] For example, the control unit 103 allocates resources (or channels) for transmitting and receiving DL signals and / or resources for transmitting and receiving UL signals based on signals received from the device 20 (e.g., data and control information) and / or data and control information obtained from higher layers. Information related to the allocated resources can be included in the control information sent to the device 20.

[0446] Control unit 103 sets PUCCH resources as an example of allocating resources for transmitting and receiving UL signals. Information related to PUCCH settings such as PUCCH cell timing mode (PUCCH setting information) can also be notified to device 20 via RRC.

[0447] Here, the transmitting unit 101 transmits wireless power to wake up the device 20. The wireless power can also be a signal such as a carrier waveform.

[0448] The transmitting unit 101 transmits information. The information can also be information A or information B. The control unit 103 can also include the information used by the device 20 to receive information B in information A. The control unit 103 can also include the information used by the device 20 to transmit signals / signals A / signals B in information / information A.

[0449] The receiving unit 202 receives signals from the device 20. The signal can be signal A or signal B. The control unit 103, in order for the device 20 to send signal A or signal B, can also receive signals from the device 20 based on information sent to the device 20. The control unit 103 can also receive signal B based on information related to signal B contained in signal A.

[0450] The transmitting unit 101 can also transmit information to the device 20 regarding the presence or absence of a signal / signal A / signal B for the device 20 to determine.

[0451] <Equipment Structure>

[0452] Figure 22 This is a block diagram illustrating an example of the structure of the device 20 involved in the implementation. Device 20 is a device with lower complexity than a narrowband Internet of Things (NB-IoT) device, such as an A-IoTUE.

[0453] Device 20 may include, for example, a receiving unit 201, a transmitting unit 202, and a control unit 203. Device 20 may communicate with base station 10 wirelessly, for example. Device 20 may also be an A-IoT device, for example.

[0454] The receiving unit 201 receives the DL signal transmitted from the base station 10. For example, the receiving unit 201 receives the DL signal under the control of the control unit 203.

[0455] The transmitting unit 202 transmits a UL signal to the base station 10. For example, the transmitting unit 202 transmits the UL signal under the control of the control unit 203.

[0456] The UL signal may also include, for example, uplink data signals and control information (e.g., UCI). It may also include information related to the processing capabilities of device 20 (e.g., UE capability). Furthermore, the UL signal may also include reference signals.

[0457] Channels used for transmitting UL signals include, for example, data channels and control channels. For instance, the data channel includes the PUSCH (Physical Uplink Shared Channel), and the control channel includes the PUCCH (Physical Uplink Control Channel). For example, device 20 uses the PUCCH to receive control information from base station 10 and uses the PUSCH to transmit uplink data signals.

[0458] The reference signals included in the UL signal may include at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, reference signals such as DMRS and PTRS are used for demodulation of uplink data signals and are transmitted using an uplink channel (e.g., PUSCH).

[0459] The control unit 203 controls the communication operations of the device 20, including the receiving processing of the receiving unit 201 and the transmitting processing of the transmitting unit 202.

[0460] For example, control unit 203 obtains data and control information from higher layers and outputs it to transmitting unit 202. Furthermore, control unit 203 may output data and control information received from receiving unit 201 to higher layers, for example.

[0461] For example, control unit 203 controls the transmission of information fed back to base station 10. The information fed back to base station 10 may include, for example, HARQ-ACK, Channel State Information (CSI), and Scheduling Request (SR). The information fed back to base station 10 may also be included in UCI. UCI is transmitted within the resources of PUCCH.

[0462] The control unit 203 configures the PUCCH resources based on the configuration information received from the base station 10 (e.g., configuration information such as the PUCCH cell timing mode notified by RRC and / or DCI). The control unit 203 determines the PUCCH resources to be used in transmitting information fed back to the base station 10. The transmitting unit 202, under the control of the control unit 203, transmits the information fed back to the base station 10 using the PUCCH resources determined by the control unit 203.

[0463] Furthermore, the channels used for transmitting DL signals and UL signals are not limited to the examples described above. For instance, the channels used for transmitting DL signals and UL signals may also include RACH (Random Access Channel) and PBCH (Physical Broadcast Channel). RACH may also be used, for example, to transmit Downlink Control Information (DCI) containing the Random Access Radio Network Temporary Identifier (RA-RNTI).

[0464] Here, the control unit 203 wakes up the device 20 based on the wireless power from the base station 10. After the device 20 is woken up, the receiving unit 201 receives the second information sent from the base station 10 based on the first information sent from the base station 10. The first information may also be information A. The second information may also be information B. The first information may also be included in the information described in 1.~7. of Proposal 1.

[0465] The receiving unit 201 can also receive the second information based on the resource information of the second information contained in the first information. The resource information can also be time-domain resources / frequency-domain resources.

[0466] The first information may also include destination information related to the device receiving the first information. The receiving unit 201 may also receive the first information based on the destination information.

[0467] The receiving unit 201 may also receive the first information and / or the second information based on pre-determined information related to the size of the first information and / or the second information. The information related to the size of the first information and / or the second information may also be pre-determined (pre-set) through specifications / setting information, for example.

[0468] The receiving unit 201 may also receive information related to the size of the first information and / or the second information from the base station 10, and receive the first information and / or the second information based on the received information.

[0469] Furthermore, the transmitting unit 202 transmits a signal to the base station 10 based on the information transmitted from the base station 10. The information transmitted from the base station 10 may also be information A. The information transmitted from the base station 10 may also include the information described in sections 1 to 8 of Proposal 2.

[0470] The transmitting unit 202 may also transmit a signal based on signal resource information contained in the information transmitted from the base station 10. The transmitting unit 202 may also transmit a signal based on information related to a predetermined signal size or information related to the signal size notified from the base station 10.

[0471] The transmitting unit 202 may also transmit a first signal and a second signal to the base station 10 based on information transmitted from the base station 10. The transmitting unit 202 may also include information related to the second signal in the first signal. The first signal may also be signal A. The second signal may also be signal B.

[0472] The transmitting unit 202 may also include information related to the resources of the second signal in the first signal. The resource information may also be time-domain resources or frequency-domain resources.

[0473] The transmitting unit 202 can also report information to the base station 10 related to the magnitude of the signal transmitted to the base station 10.

[0474] Furthermore, the control unit 203 determines whether or not to transmit a signal to the base station 10 based on information transmitted from the base station 10. The information transmitted from the base station 10 may also be the information described in sections 1 to 8 of Proposal 3.

[0475] The information sent from base station 10 may, for example, be information for a DT (Delayed Transmission) to be terminated in device 20. The information sent from base station 10 may also be information for a DO-DTT (Direct Response Time Trial) to trigger signal transmission from the device.

[0476] The control unit 203 can also determine whether or not a signal is transmitted based on the resources of the information sent from the base station 10. The resources can be time-domain resources or frequency-domain resources.

[0477] The control unit 203 can also determine whether or not a signal is transmitted based on the code resources of the information transmitted from the base station 10. The code resources can also be the reference sequence index / cyclic shift / orthogonal overlay code index used in the information transmitted from the base station 10.

[0478] The control unit 203 can also determine whether or not a signal is transmitted based on an indication contained in the information sent from the base station 10.

[0479] The above provides an explanation of this disclosure. Furthermore, the distinctions between items mentioned above are not essential distinctions in this disclosure. Items described in two or more items may be combined as needed, or items described in one item may be applied to items described in other items (as long as there is no contradiction).

[0480] <Hardware architecture, etc.>

[0481] The block diagrams used in the description of the above embodiments illustrate functional units. These functional blocks (structural units) are implemented through any combination of at least one of hardware and software. Furthermore, the implementation method of each functional block is not particularly limited. That is, each functional block can be implemented using a single device that is physically or logically combined, or by directly or indirectly (e.g., using wired, wireless, etc.) connecting two or more physically or logically separate devices and using these multiple devices. Functional blocks can also be implemented by incorporating software into the aforementioned single device or multiple devices.

[0482] The functions include judgment, decision, determination, calculation, calculation, processing, derivation, investigation, search, confirmation, receiving, sending, output, access, resolution, selection, choosing, establishment, comparison, assumption, expectation, regard as, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assigning, but are not limited to these. For example, a functional block (structural unit) that implements the sending function is called a transmitting unit or transmitter. Each of these functions, as described above, has no particular limitation on its implementation method.

[0483] For example, the base station, device, etc. in one embodiment of this disclosure can also function as a computer for processing the wireless communication method of this disclosure. Figure 23 This diagram illustrates an example of the hardware structure of the base station and device involved in this embodiment. The base station 10 and device 20 described above can also be physically configured as a computer device including a processor 1001, a memory 1002, a storage device 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

[0484] Additionally, in the following description, the term "device" can be replaced with circuit, equipment, unit, etc. The hardware structure of base station 10 and device 20 can be configured to include one or more of the devices shown in the figures, or it can be configured not to include any of the devices.

[0485] The functions of base station 10 and device 20 are realized by reading specific software (programs) into hardware such as processor 1001 and memory 1002, so that processor 1001 performs calculations and controls communication based on communication device 1004, or controls at least one of reading and writing data in memory 1002 and storage device 1003.

[0486] The processor 1001 enables the operating system to operate and control the computer as a whole. The processor 1001 may also be a central processing unit (CPU) that includes interfaces with peripheral devices, control devices, arithmetic units, registers, etc. For example, the control unit 103 and control unit 203 described above may also be implemented by the processor 1001.

[0487] Furthermore, the processor 1001 reads programs (program code), software modules, data, etc., from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and performs various processes accordingly. As a program, a program that causes the computer to perform at least a portion of the operations described in the above embodiments can be used. For example, the control unit 203 of the device 20 can also be implemented by a control program stored in the memory 1002 and operated by the processor 1001; similar implementations can be made for other functional blocks.

Furthermore, the driver assistance system unit 2030 sends and receives various information via a communication module 2013 and implements driver assistance or autonomous driving functions.

[0540] The communication module 2013 can communicate with the microprocessor 2031 and the constituent elements of the vehicle 2001 via the communication port.

[0545] <Meaning and Explanation of Terms>

[0546] The terms "determining" and "determining" as used in this disclosure encompass a wide variety of actions. For example, "determining" or "determining" can include actions such as judging, calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and ascertaining. Furthermore, "determining" or "determining" can include actions such as receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in memory). Additionally, "determining" or "determining" can include actions such as resolving, selecting, choosing, establishing, and comparing. That is, "judgment" and "decision" can include situations where certain actions are regarded as having been "judged" or "decided". In addition, "judgment (decision)" can also be rewritten as "assuming", "expecting", "considering", etc.

[0547] The terms “connected,” “coupled,” or all variations thereof, refer to all direct or indirect connections or combinations between two or more elements, and can include cases where there is one or more intermediate elements between two mutually “connected” or “coupled” elements. The connection or combination between elements can be physical, logical, or a combination thereof. For example, “connected” can also be replaced by “access.” In the context of this disclosure, it is possible to consider two elements being mutually “connected” or “coupled” using at least one or more wires, cables, or printed electrical connections, and as several non-limiting and non-exclusive examples, using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (both visible and invisible) region.

[0548] <Reference signal>

[0549] The reference signal can also be abbreviated as RS (Reference Signal), and can also be called a pilot according to the applied standard.

[0550] <Meaning of "based on">

[0551] In the present disclosure, the description of "based on" used herein does not mean "only based on" unless specifically stated. In other words, the description of "based on" means both "only based on" and "at least based on".

[0552] <"First", "second">

[0553] Any reference to elements using the designations "first", "second", etc. used in the present disclosure does not comprehensively limit the quantity or order of these elements. These designations can be used as a convenient method for distinguishing between two or more elements in the present disclosure. Therefore, the reference to the first and second elements does not mean that only two elements can be used, or that the first element must take precedence over the second element in a certain form.

[0554] <Unit>

[0555] In the structure of each of the above devices, "unit" can also be replaced by "section", "circuit", "device", etc.

[0556] <Open form>

[0557] In the present disclosure, when using "include", "including", and their variants, these terms, like the term "comprising", have an inclusive meaning. Further, the term "or" used in the present disclosure does not mean the exclusive or meaning.

[0558] <Time units such as TTI, frequency units such as RB, wireless frame structure>

[0559] A radio frame can also be composed of one or more frames in the time domain. One or more frames in the time domain can also be called subframes. Further, a subframe can also be composed of one or more time slots in the time domain. A subframe can also be a fixed time length (e.g., 1 ms) independent of the numerology.

[0560] A parameter set can also be a set of communication parameters applied in at least one of the transmission and reception of a signal or channel. For example, a parameter set can also 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 transmitter and receiver in the frequency domain, and specific windowing processing performed by the transmitter and receiver in the time domain.

[0561] In the time domain, a time slot can also 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 also be a time unit based on a set of parameters.

[0562] A time slot can also contain multiple mini-time slots. Each mini-time slot can also consist of one or more symbols in the time domain. Furthermore, a mini-time slot can also be called a sub-time slot. A mini-time slot can also consist of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-time slot can also be called PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using mini-time slots can also be called PDSCH (or PUSCH) mapping type B.

[0563] 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 also be referred to by their respective other names.

[0564] For example, a subframe can also 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, at least one of a subframe and a TTI can be a subframe in existing LTE (1ms), a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. In addition, the unit representing TTI may not be called a subframe, but rather a time slot, mini-time slot, etc.

[0565] 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 radio resources (frequency bandwidth, transmit power, etc., available to each user terminal) in TTI units. However, the definition of TTI is not limited to this.

[0566] TTI can also be a unit of time for transmitting channel-coded data packets (transmission blocks), code blocks, codewords, etc., and can also be a unit of processing such as scheduling and link adaptation. In addition, when a TTI is given, the actual time interval (e.g., the number of symbols) mapped to transmission blocks, code blocks, codewords, etc. can be shorter than the TTI.

[0567] In addition, where 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 also be the minimum time unit for scheduling. Furthermore, the number of time slots (mini-time slots) constituting the minimum time unit of the schedule can also be controlled.

[0568] A TTI with a duration of 1ms can also be referred to as a normal TTI (TTI in LTE Rel.8-12), standard TTI, long TTI, normal subframe, standard subframe, long subframe, time slot, etc. A TTI shorter than a normal TTI can also be referred to as a shortened TTI, short TTI, partial TTI (partial or fractional TTI), shortened subframe, short subframe, mini time slot, sub-time slot, time slot, etc.

[0569] In addition, long TTIs (e.g., normal TTIs, subframes, etc.) can be replaced with TTIs with a duration of more than 1ms, and short TTIs (e.g., shortened TTIs, etc.) can be replaced with TTIs with a duration of less than long TTIs but more than 1ms.

[0570] A resource block (RB) is a unit of resource allocation in both the time and frequency domains. In the frequency domain, it can also contain one or more consecutive subcarriers. The number of subcarriers in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers in an RB can also be determined based on the parameter set.

[0571] Furthermore, the time domain of an RB can also contain one or more symbols, or it can be the length of a time slot, a mini-time slot, a subframe, or a TTI. A TTI, a subframe, etc., can also be composed of one or more resource blocks.

[0572] In addition, one or more RBs can also be referred to as Physical Resource Block (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB Pair, RB Pair, etc.

[0573] Furthermore, a resource block can also consist of one or more resource elements (REs). For example, an RE can also be a radio resource area consisting of a subcarrier and a symbol.

[0574] The Bandwidth Part (BWP) (also known as partial bandwidth, etc.) can also represent a subset of consecutive common resource blocks (RBs) used for a certain parameter set in a certain carrier. Here, common RBs can also be determined by the index of RBs based on the common reference point of that carrier. PRBs can also be defined in a BWP and appended with numbers within that BWP.

[0575] A BWP can also include a UL BWP and a DL BWP. For a UE, one or more BWPs can be set within a single carrier.

[0576] At least one of the configured BWPs can be active, and the UE may not intend to transmit or receive specific signals / channels outside of the active BWPs. Furthermore, terms such as "cell" and "carrier" in this disclosure can be replaced with "BWP".

[0577] The structures described above, such as radio frames, subframes, time slots, mini-time slots, and symbols, 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, and the number of symbols in a TTI, symbol length, and cyclic prefix (CP) length can be varied in many ways.

[0578] Maximum transmit power

[0579] The term "maximum transmit power" as used in this disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated UE maximum transmit power).

[0580] <article>

[0581] In this disclosure, for example, in cases where articles are added through translation, such as a, an, and the in English, the disclosure may also include cases where the noun following these articles is in a plural form.

[0582] <"Different">

[0583] In this disclosure, the term "A is different from B" can also mean "A and B are different from each other." Additionally, the term 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."
