[0039] FIG. 1 illustrates a communication structure that can be provided in a 6G system according to one embodiment of the present disclosure. The embodiment of FIG. 1 can be combined with various embodiments of the present disclosure.
[0040] New network characteristics in 6G may include:
[0041] - Satellite integrated network
[0042] - Connected Intelligence: Unlike previous generations of wireless communication systems, 6G is revolutionary, upgrading the wireless evolution from "connected objects" to "connected intelligence." AI can be applied at every stage of the communication process (or at every signal processing step, as described below).
[0043] - Seamless integration of wireless information and energy transfer
[0044] - Ubiquitous super 3D connectivity: Access to networks and core network functions of drones and very low Earth orbit satellites will create super 3D connectivity in 6G ubiquitous.
[0045] Some general requirements for the new network characteristics of 6G, such as the above, may be as follows:
[0046] - small cell networks
[0047] - Ultra-dense heterogeneous network
[0048] - High-capacity backhaul
[0049] - Radar technology integrated with mobile technology: High-precision localization (or location-based services) through communications is a key feature of 6G wireless communication systems. Therefore, radar systems will be integrated with 6G networks.
[0050] - Softwarization and virtualization
[0051] Below, the core implementation technologies of the 6G system are described.
[0052] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. This means AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a crucial role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. Furthermore, AI can facilitate rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.
[0053] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by utilizing sub-THz communication with a wide bandwidth and applying advanced massive MIMO technology. THz waves, also known as sub-millimeter waves, typically refer to the frequency range between 0.1 THz and 10 THz with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz to 300 GHz band (Sub-THz band) is considered a major portion of the THz band for cellular communications. Adding the Sub-THz band to the mmWave band will increase the capacity of 6G cellular communications. Among the defined THz bands, 300 GHz to 3 THz lies in the far infrared (IR) frequency band. While part of the optical band, the 300 GHz to 3 THz band lies at the boundary of the optical band, immediately following the RF band. Therefore, this 300 GHz to 3 THz band exhibits similarities to RF. Figure 2 illustrates the electromagnetic spectrum according to one embodiment of the present disclosure. The embodiment of FIG. 2 can be combined with various embodiments of the present disclosure. Key characteristics of THz communications include (i) widely available bandwidth to support very high data rates, and (ii) high path loss at high frequencies (highly directional antennas are essential). The narrow beamwidth generated by the highly directional antenna reduces interference. The small wavelength of THz signals allows for a much larger number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array technologies to overcome range limitations.

[0067] Unmanned aerial vehicles (UAVs): UAVs, or drones, will be a key element in 6G wireless communications. In most cases, high-speed data wireless connectivity can be provided using UAV technology. Base stations (BSs) can be installed on UAVs to provide cellular connectivity. UAVs may offer specific capabilities not found in fixed BS infrastructure, such as easy deployment, robust line-of-sight links, and controlled mobility. During emergencies such as natural disasters, deploying terrestrial communications infrastructure is not economically feasible and sometimes cannot provide services in volatile environments. UAVs can easily handle these situations. UAVs will become a new paradigm in wireless communications. This technology facilitates three fundamental requirements for wireless networks: enhanced mobile broadband (eMBB), URLLC, and mMTC. UAVs can also support various purposes, such as enhancing network connectivity, fire detection, disaster emergency services, security and surveillance, pollution monitoring, parking monitoring, and accident monitoring. Therefore, UAV technology is recognized as one of the most important technologies for 6G communications.
[0068] - Autonomous driving (self-driving): V2X (vehicle to everything), a key element in building autonomous driving infrastructure, can be a technology that allows cars to communicate and share with various elements on the road for autonomous driving, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) wireless communication. Fast transmission speeds and low-latency technologies are essential to maximize autonomous driving performance and ensure high safety. Furthermore, in the future, autonomous driving will go beyond simply providing warnings or guidance messages to drivers and may require active intervention in vehicle operation and direct control of the vehicle in dangerous situations. To this end, the amount of information that needs to be transmitted and received may become enormous, so 6G is expected to maximize autonomous driving with faster transmission speeds and lower latency than 5G.
[0069] - Non-terrestrial networks (NTN): NTN may refer to a network or network segment that uses radio frequency (RF) resources mounted on a satellite (or unmanned aerial system (UAS) platform). FIG. 3 illustrates an example of a typical NTN scenario based on a transparent payload according to an embodiment of the present disclosure. FIG. 4 illustrates an example of a typical NTN scenario based on a regenerative payload according to an embodiment of the present disclosure. The embodiments of FIG. 3 or FIG. 4 may be combined with various embodiments of the present disclosure. Referring to FIG. 3, a satellite (or UAS platform) may create a service link with a UE. The satellite (or UAS platform) may be connected to a gateway via a feeder link. The satellite may be connected to a data network via the gateway. A beam footprint may refer to an area where a signal transmitted by a satellite can be received. Referring to Figure 4, a satellite (or UAS platform) can establish a service link with a UE. A satellite (or UAS platform) connected to a UE can be connected to another satellite (or UAS platform) via an inter-satellite link (ISL). The other satellite (or UAS platform) can be connected to a gateway via a feeder link. Based on the playback payload, a satellite can be connected to a data network through another satellite and the gateway. If an ISL does not exist between a satellite and another satellite, a feeder link between the satellite and the gateway may be required. Figures 3 and 4 are merely examples of NTN scenarios, and NTN can be implemented based on various scenarios.For example, a satellite (or UAS platform) may implement a transparent or regenerative (with onboard processing) payload. For example, a satellite (or UAS platform) may generate multiple beams over a designated service area depending on the field of view of the satellite (or UAS platform). For example, the field of view of the satellite (or UAS platform) may vary depending on the onboard antenna diagram and minimum elevation angle. For example, a transparent payload may include radio frequency filtering, frequency conversion, and amplification. Therefore, the waveform signal repeated by the payload may not be altered. For example, a regenerative payload may include radio frequency filtering, frequency conversion and amplification, demodulation / decoding, switching and / or routing, and coding / modulation. For example, a regenerative payload may be substantially equivalent to equipping the satellite (or UAS platform) with all or part of the base station functionality.
[0070] - Integrated Sensing and Communication (ISAC): Wireless sensing is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the characteristics of the environment and / or objects within the environment. Because radio frequency sensing does not require a device to connect to the object through a network, it can provide a service for object positioning without a device. The ability to obtain range, velocity, and angle information from radio frequency signals can enable a wide range of new capabilities, such as various object detection, object recognition (e.g., vehicles, humans, animals, UAVs), and high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to a variety of industries (e.g., drones, smart homes, V2X, factories, railways, public safety, etc.), enabling applications such as intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, and health and traffic management. In some cases, wireless sensing can utilize non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP-based sensing. For example, the operation of wireless sensing services, i.e., sensing operations, may depend on the transmission, reflection, and scattering of wireless sensing signals. Therefore, wireless sensing offers an opportunity to enhance existing communication systems from a communication network to a wireless communication and sensing network.
[0071] Meanwhile, the Intelligent Transport System (ITS) has recently expanded beyond traditional modes of transportation (e.g., trains, automobiles, etc.) to encompass expanded mobility, such as drones and mobile robots. Connectivity between vehicles and infrastructure is a critical topic in ITS, and significant development is being conducted to improve the communication performance of connected mobility.
[0072] For example, by combining internal and external communication systems within a vehicle and exchanging data or information based on this, safety or traffic efficiency can be improved from an ITS perspective. For example, in a car, the vehicle's internal communication system can handle communication between sensors and electronic control systems that collect information about the vehicle's internal operating status, vehicle movement, and surrounding environment. The vehicle's external communication system can handle communication between the communication infrastructure and other mobility systems.
[0073] For example, the internal communication systems of mobility devices exist in a variety of systems developed in-house by manufacturers and component suppliers. Representative communication systems include MOST (Media Oriented System Transport), LIN (Local Interconnected Network), and CAN (Controller Area Network), along with performance-enhanced versions such as CAN FD (Flexible Data-rate) and FlexRay.
[0074] For example, external communication systems for mobility include direct communication (e.g., Dedicated Short-Range Communication (DSRC), 3GPP PC5) and mobile communication (e.g., LTE or NR), and standards organizations such as IEEE and 3GPP are developing new technologies to improve communication performance. Recently, there has been active discussion on methods to improve communication performance based on artificial intelligence (AI) models. That is, the goal is to enhance CSI (Channel State Information) feedback, beam management, or positioning accuracy by utilizing learned AI models.
[0075] Meanwhile, research is currently underway to train AI models using limited information within the communication module or information exchanged between base stations (e.g., past CSI or location information). However, due to the nature of mobility, which allows for diverse movements in 3D space and the uncertainty of the body's mobility and / or movement, CSI management, beam management, and precision positioning can be challenging. For example, in the case of automobiles, rolling can occur when the vehicle passes over an uneven road surface. Alternatively, pitching can occur due to sudden stops or starts. Alternatively, for example, in the case of drones, turbulence during flight can prevent smooth flight. For example, in the aforementioned cases, unpredictable body movements within the communication module mounted on the body can cause problems with CSI and beam management. Alternatively, for example, a sudden rotation of the fuselage may cause the performance of the communication module and antenna performing beam forming to deteriorate.
[0076] In the present disclosure, a method for extracting movement information of a mobility when the mobility communicates with an external entity (e.g., a base station and / or a Road Side Unit (RSU) and / or an ITS terminal) and transmitting it to a communication module, and a device supporting the same are proposed as follows.
[0077] In addition, in the present disclosure, when information is transmitted, the format of information transmitted from an electronic device (e.g., a gateway or a motion control unit) to a communication terminal in the case of an internal network of mobility, or the format of information transmitted from an application layer to an access layer within the communication terminal, is proposed as follows.
[0078] For example, among the vast amount of information exchanged within the mobility network, data that can represent mobility information for use in the AI model of the communication module can be extracted. In this case, for example, the mobility information for a defined mobility can be defined as 1) the current motion information of the mobility (e.g., 3-axis speed or 3-axis rotation) and 2) the expected and / or planned path of the mobility.
[0079] For example, the motion information of the first mobility may be a three-axis linear motion vector and a three-axis rotational motion vector calculated from measurements of internally installed sensors (e.g., a GNSS sensor, an inertial measurement unit (IMU), an accelerometer, a gyroscope sensor, a geomagnetic sensor, a gravity sensor, or a rotation vector sensor, etc.). In addition, for example, the mobility may generate information by processing measurements obtained from sensors, and the processed information may be input into an AI model as described below. For example, the mobility may perform dead reckoning by performing calculations based on measurements obtained from a GNSS sensor and measurements obtained from an IMU sensor, and the processed information obtained based on this may be used as an input parameter of an AI model as described below.
[0080] For example, the predicted path or planned path of the second mobility may mean predicted path information calculated based on the current location, speed, direction, driver or operator input, etc., for the future movement path of the mobility, or pre-planned path information considering movement to the destination and obstacle avoidance. If, for example, a communication module performs communication between mobilities or infrastructures including V2X and exchanges the predicted path or planned path at this time, this information can be used instead. For example, in the Society of Automotive Engineers (SAE) standard of V2X, if a mobility transmits a Basic Safety Message (BSM), the DE_PathPrediction value configured in the message can be utilized.
[0081] Figure 5 illustrates an example of a mobility information format. For example, the two types of mobility information described above can be exchanged in a format like Figure 5.
[0082] Referring to FIG. 5, for example, the first motion information may include a velocity vector of the x, y, and z axes and a rotation vector of the x, y, and z axes, and at this time, the heading value and / or WGS84 (World Geodetic System 1984), which are the direction of movement of the mobility, may be used as the cardinal direction of the x, y, and z. For example, the heading direction of the mobility may be defined as the x-axis, the axis perpendicular to the x-axis in a plane perpendicular to the direction of gravity as the y-axis, and the direction of gravity as the z-axis. For example, if WGS84 is used as the standard, the origin may be set at the center of mass of the Earth, the x-axis may be set in the direction of the intersection of the Greenwich meridian and the equator, the y-axis may be set in the direction of 90 degrees east longitude, and the z-axis may be set in the direction of the North Pole, and the velocity vector and rotation vector may be expressed. For example, for the elements of the velocity vector and the rotation vector, they can be expressed as absolute values and / or relative values and / or change probability [%].
[0083] For example, the second path information may be a predicted path or a planned path calculated internally, and the path may be represented by a list of location points or a list of radii of curvature, or may be represented in other ways.
[0084] Figure 6 illustrates an example of utilizing the path prediction data element of the BSM (Basic Safety Message). The embodiment of Figure 6 can be combined with various embodiments of the present disclosure. For example, if a communication terminal exchanges a BSM, it can be used as illustrated in Figure 6. For example, the PathPrediction data element of the BSM can be composed of a list of radii of curvature.
[0085] Figure 7 illustrates an example of representing a path as a list of points. The embodiment of Figure 7 can be combined with various embodiments of the present disclosure.
[0086] For example, the confidence value / level commonly included in the above two pieces of information (motion information, path information) can represent information such as certainty or expected error.
[0087] For example, the AI model may be located in the application layer or the access layer of the communication module. For example, in the former case (where the AI model is located in the application layer of the communication module), the mobility information derived above can be transmitted from the internal mobility network to the communication module.
[0088] FIG. 8 illustrates an example of mobility information being transmitted from a peripheral electronic device to a communication module. The embodiment of FIG. 8 can be combined with various embodiments of the present disclosure.
[0089] Referring to FIG. 8, the above-described mobility information can be transmitted from another electronic device to a telematic module via a gateway.
[0090] FIG. 9 illustrates an example of mobility information being transmitted from the application layer within a communication module to the access layer. The embodiment of FIG. 9 can be combined with various embodiments of the present disclosure.
[0091] Referring to FIG. 9, if the AI model is located in the access layer of the communication module, each sensor information can be collected in the application layer of the communication module, and mobility mobility information can be calculated and then transmitted to the access layer within the communication module.
[0092] Additionally, it can be used as an input parameter of the AI model of a base station, for example, in communication between base stations.
[0093] Figure 10 illustrates an example of interaction between mobility information and a base station. The embodiment of Figure 10 can be combined with various embodiments of the present disclosure.
[0094] Referring to FIG. 10, a mobility can report to a base station that its mobility information is being provided to a communication module in an internal network, and the base station can request or instruct the method and / or conditions for transmitting the mobility information of the mobility being exchanged to the base station. Furthermore, for example, a mobility can transmit its own mobility information to the base station at the request or instruction of the base station.
[0095] For example, mobility information transmitted to a communication module can be utilized as an input parameter of an AI model to enable external communication with improved communication performance (e.g., beam and / or CSI (channel state information) prediction). Furthermore, for example, when there is interaction between base stations (e.g., reporting, requesting, responding, etc.), mobility information of the mobility can be utilized as an input parameter of an AI model within the base station.
[0096] Fig. 11 illustrates an AI-based beam management method utilizing motion information. The embodiment of Fig. 11 can be combined with various embodiments of the present disclosure.
[0097] Referring to FIG. 11, UE A and UE B may be mobilities that perform beam-based communication. For example, UE A and UE B may be mobilities that can move in a three-dimensional space, such as vehicles, drones, and mobile robots. For example, UE A may select a beam that can be paired with UE B by transmitting an RS (reference signal) to UE B. That is, for example, UE A may perform beam forming or beam switching to perform beam-based communication with UE B. For example, UE A may perform beam forming to determine a beam aligned with UE B (or a beam matched with the beam of UE B) (1110), and transmit data, etc. to UE B based on the beam (1110). Meanwhile, based on the state of UE A or the driving / flight environment around UE A, a change in the motion of UE A that UE A did not anticipate, such as rolling or pitching, may occur (1120). For example, the beam (1110) determined by UE A performing beam forming may no longer be aligned with UE B (1130). That is, for example, if UE A does not maintain the beam (1110) and perform beam management, beam-based communication with UE B may become impossible. In this case, for example, UE A may obtain information related to the motion of UE A based on sensors installed inside. For example, the information related to the motion may include processed information obtained by performing a calculation based on one or more measurement values as well as measurement values obtained from sensors installed inside UE A. For example, UE A may use information related to the motion of UE A as an input parameter of an AI model.For example, the information used as an input parameter of the AI model may be processed information obtained by performing a calculation based on one or more measurement values as well as measurement values obtained from sensors. For example, UE A may perform dead reckoning by performing a calculation based on measurement values obtained from a GNSS sensor installed inside UE A and measurement values obtained from an IMU sensor, and may use the processed information obtained based on this as an input parameter of the AI model. Meanwhile, UE A may input information related to the motion of UE A into the AI model to obtain information related to beam prediction. For example, UE A may perform beam forming again based on the information related to beam prediction obtained from the AI model. For example, UE A may perform beam forming again to determine a beam aligned with UE B (or a beam matched with the beam of UE B) (1140), and transmit data, etc. to UE B based on the beam (1140). Alternatively, for example, UE A may perform beamforming again to determine the thickness of the beam associated with the new beamforming. For example, UE A may measure the communication status (or quality) based on the beam associated with the previous beamforming and determine whether the communication status (or quality) is below (or above) a threshold. For example, if UE A determines that the communication status (or quality) based on the beam associated with the previous beamforming is degraded, UE A may perform beamforming again and determine the thickness of the beam associated with the newly performed beamforming to be sharper or thicker than the thickness of the beam associated with the previous beamforming so as to improve the communication status (or quality).That is, for example, UE A can perform beam management to maintain beam-based communication with UE B based on the results obtained by inputting information related to the motion of UE A into an AI model.
[0098] According to various embodiments of the present disclosure, the mobility information of the transmitted mobility can be utilized as input to an AI (Artificial Intelligence) model installed within a communication module, which can improve communication performance (e.g., channel state information (CSI) prediction, beam prediction, or positioning accuracy). Specifically, even if an unexpected motion occurs in the mobility, the mobility can input the motion information into the AI model and determine the direction or thickness of the beam from the acquired information, thereby minimizing operations such as beam measurement or beam sweeping that the mobility must perform to maintain beam-based communication. That is, for example, resources related to beam RS (beam reference signal) for beam pairing or beam selection can be efficiently allocated. Or, for example, power of the mobility can be saved by efficiently performing operations related to beam management. Alternatively, the reliability of beam-based communication can be ensured by reducing delays that may occur, for example, by performing operations related to beam management.
[0099] FIG. 12 illustrates a method for a first device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.
[0100] Referring to FIG. 12, in step S1210, the first device may obtain information related to the motion of the first device based on at least one sensor. In step S1220, the first device may transmit the information related to the motion to an artificial intelligence (AI) model. In step S1230, the first device may perform beam management based on the results obtained from the AI model.
[0101] Additionally, for example, the first device can perform first beam forming. For example, whether to maintain a beam associated with the first beam forming for the beam management can be determined based on a result obtained from the AI model. For example, based on the fact that the direction of the beam associated with the first beam forming is not aligned with that of the second device, second beam forming for the beam management can be performed using the result obtained from the AI model. For example, the direction of the beam associated with the second beam forming can be determined based on information related to beam prediction obtained from the AI model. For example, based on the information related to beam prediction, the direction of the beam associated with the second beam forming can be determined to be a more aligned direction than the direction of the beam associated with the first beam forming. For example, the thickness of the beam associated with the second beam forming can be determined based on information related to beam prediction obtained from the AI model. In this case, for example, based on information related to the beam prediction, the thickness of the beam related to the second beam forming may be determined to be sharper or thicker than the thickness of the beam related to the first beam forming. In this case, for example, the thickness of the beam related to the second beam forming may be determined based on the state of communication quality based on the beam related to the first beam forming. For example, based on the information related to the motion being transmitted to the AI model, information related to at least one of the direction, angle, power, covered range, or thickness of the beam for beam management may be acquired.
[0102] For example, the motion-related information may include at least one of (i) information related to a three-axis linear motion vector of the first device, (ii) information related to a three-axis rotational motion vector of the first device, or (iii) information related to reliability.
[0103] For example, information related to the motion may be generated based on a value measured by at least one sensor, such as at least one of a global navigation satellite system (GNSS) sensor, an inertial measurement unit (IMU) sensor, an acceleration sensor, a gyroscope sensor, a geomagnetic sensor, a gravity sensor, or a rotation vector sensor.
[0104] For example, based on the results obtained from the AI model, the state of a channel related to a beam determined based on the beam management can be predicted.
[0105] For example, based on the AI model being located in the application layer of the first device, information related to the motion may be transmitted to a telematic module related to the application layer of the first device through the internal network of the first device.
[0106] For example, based on the AI model being located in the access layer of the first device, information related to the motion can be transmitted from the application layer of the first device to the access layer of the first device.
[0107] Additionally, for example, the first device may transmit information related to at least one of a predicted path or a planned path of the first device to the AI model. For example, information related to beam management may be obtained from the AI model based on (i) information related to the motion, and (ii) information related to at least one of the predicted path or the planned path.

[0135] FIG. 16 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 16 can be combined with various embodiments of the present disclosure.
[0136] Referring to FIG. 16, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operations / functions of FIG. 16 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 15. The hardware elements of FIG. 16 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 15. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 15. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 15, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 15.
[0137] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 16. Here, the codeword is an encoded bit sequence of an information block. The information block can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).
[0138] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010). The scramble sequence used for scrambling is generated based on an initialization value, and the initialization value may include ID information of the wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by a precoding matrix W of N*M. Here, N is the number of antenna ports, and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on complex modulation symbols. In addition, the precoder (1040) can perform precoding without performing transform precoding.
[0139] The resource mapper (1050) can map modulation symbols of each antenna port to time-frequency resources. The time-frequency resources can include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. The signal generator (1060) generates a wireless signal from the mapped modulation symbols, and the generated wireless signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) can include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.
[0140] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 16. For example, a wireless device (e.g., 100, 200 of FIG. 15) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module.
