[0038] FIG. 1 illustrates a device-to-device communication procedure according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0039] Referring to FIG. 1, in step S101, a first device and a second device can perform synchronization. For example, the first device can be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device can be a base station, a network, a RAN node, an NTN node / cell, a TRP, a terminal and / or at least one of the devices proposed in the present disclosure. For example, the first device can perform an initial cell search operation. For example, the first device can detect at least one synchronization signal transmitted by the second device according to a predefined rule. Here, for example, the synchronization signal can include a plurality of synchronization signals classified according to a structure or purpose (e.g., a primary synchronization signal, a secondary synchronization signal, etc.). Through this, the first device can identify the boundaries of the frame, subframe, time unit, slot, and / or symbol of the second device, and the first device can obtain information about the second device (e.g., a cell identifier).

[0040] In step S103, the first device can obtain system information transmitted by the second device. For example, the system information may include information related to the properties, characteristics, and / or capabilities of the second device required to connect to the second device and use the service. For example, the system information may be classified according to content (e.g., whether it is essential for connection), transmission structure (e.g., the channel used, whether it is provided on-demand), etc. For example, the system information may be classified into a master information block (MIB) and a system information block (SIB). For example, if necessary, the first device may transmit a signal requesting system information before receiving the system information. For example, the request and provision of system information may be performed after a random access procedure described below.

[0041] In step S105, the first device and the second device can perform a random access procedure. For example, the first device can transmit and / or receive at least one message (e.g., a random access preamble, a random access response message, etc.) for the random access procedure based on information related to a random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device can transmit a preamble (e.g., Msg1) through the random access channel, the first device can receive a random access response message (e.g., Msg2), the first device can transmit a message (e.g., Msg3) including information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device can receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be sent and received as one message (e.g., MsgA), and / or Msg2 and Msg4 can be sent and received as one message (e.g., MsgB).

[0042] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer that controls a connection (e.g., a radio resource control (RRC) layer), a layer that handles mapping between logical channels and transport channels (e.g., a media access control (MAC) layer), a layer that handles physical channels (e.g., a physical (PHY) layer), etc. For example, the first device and the second device may perform at least one of signaling for establishing a connection, signaling for determining settings related to communication, and / or signaling for indicating allocated resources. For example, the control information may be signaled / transmitted via a control channel. For example, the control information and / or the control channel may be used to schedule at least one of data, a data channel (e.g., a shared channel), and / or control information on the data channel.

[0043] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process, transmit, and / or receive data based on signaling of control information. For example, when transmitting data, the first device or the second device may perform at least one of channel encoding, rate matching, scrambling, constellation mapping, layer mapping, waveform modulation, antenna mapping, and / or resource mapping on the information bits. For example, when receiving data, the first device or the second device may perform at least one of signal extraction from resources, waveform demodulation for each antenna, signal arrangement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0044] For example, the layers of a radio interface protocol between a first device and a second device can be divided into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, a physical layer belonging to the first layer can provide an information transfer service using a physical channel, and an RRC (radio resource control) layer located in the third layer can play a role in controlling radio resources between the first device and the second device. For this purpose, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0045] FIG. 2 illustrates a radio protocol architecture according to an embodiment of the present disclosure. The embodiment of FIG. 2 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. For example, (a) of FIG. 2 may illustrate a radio protocol stack of a user plane for uplink communication or downlink communication, and (b) of FIG. 2 may illustrate a radio protocol stack of a control plane for uplink communication or downlink communication. For example, (c) of FIG. 2 may illustrate a radio protocol stack of a user plane for device-to-device communication, and (d) of FIG. 2 may illustrate a radio protocol stack of a control plane for device-to-device communication.

[0046] For example, the physical layer can provide information transmission services to upper layers using physical channels. For example, the physical layer can be connected to the upper layer, the medium access control (MAC) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through the transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted over the wireless interface. For example, data can be transmitted between different physical layers (e.g., between the physical layers of a first device and a second device) through a physical channel. For example, the physical channel can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and time and frequency can be utilized as radio resources.

[0047] For example, the MAC layer can provide services to the upper layer, the radio link control (RLC) layer, through logical channels. For example, the MAC layer can provide a mapping function from multiple logical channels to multiple transport channels. For example, the MAC layer can provide a logical channel multiplexing function by mapping multiple logical channels to a single transport channel. For example, the MAC sublayer can provide data transmission services on logical channels.

[0048] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee the various quality of service (QoS) required by radio bearers (RBs), the RLC layer can provide three operating modes: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat request (ARQ).

[0049] For example, the RRC (radio resource control) layer can be defined only in the control plane. For example, the RRC layer can be responsible for controlling logical channels, transport channels, and physical channels in relation to the configuration, re-configuration, and release of radio bearers. For example, an RB can mean a logical path provided by a first layer (e.g., a physical layer) and a second layer (e.g., a MAC layer, an RLC layer, a PDCP (packet data convergence protocol) layer, a SDAP (service data adaptation protocol) layer, etc.) for data transmission between a first device and a second device.

[0050] For example, the functions of the PDCP layer in the user plane may include forwarding of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include forwarding of control plane data and ciphering / integrity protection.

[0051] For example, establishing an RB can refer to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. For example, RBs can be divided into two types: signaling radio bearers (SRBs) and data radio bearers (DRBs). For example, SRBs can be used as a channel to transmit RRC messages in the control plane, while DRBs can be used as a channel to transmit user data in the user plane.

[0052] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) for transmitting system information, and / or a downlink shared channel (SCH) for transmitting user traffic or control messages. For example, traffic or control messages of a downlink multicast or broadcast service may be transmitted through the downlink SCH, or may be transmitted through a separate downlink multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) for transmitting initial control messages, and / or an uplink shared channel (SCH) for transmitting user traffic or control messages. For example, a logical channel located above a transmission channel and mapped to the transmission channel may include at least one of a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and / or a multicast traffic channel (MTCH).

[0053] FIG. 3 illustrates the structure of a wireless frame according to an embodiment of the present disclosure. The embodiment of FIG. 3 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0054] Referring to FIG. 3, for example, a radio frame may be used in uplink transmission, downlink transmission, and / or device-to-device transmission. For example, a radio frame may have a length of 10 ms and may be defined as two 5 ms half-frames (HF). For example, a half-frame may include five 1 ms subframes (SF). For example, a subframe may be divided into one or more slots, and the number of slots within a subframe may be determined according to a subcarrier spacing (SCS). For example, each slot may include 12 or 14 OFDM (A) symbols, depending on a cyclic prefix (CP).

[0055] For example, when normal CP is used, each slot can contain 14 symbols. For example, when extended CP is used, each slot can contain 12 symbols. Here, for example, the symbols can contain OFDM symbols (or CP-OFDM symbols), SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0056] Table 2 below shows the number of symbols per slot (N) depending on the SCS setting (u) when normal CP or extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot) is an example.

[0057] CP type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slot Normal CP15kHz (u=0)1410130kHz (u=1)1420260kHz (u=2)14404120kHz (u=3)14808240kHz (u=4)1416016Extended CP60kHz (u=2)12404

[0058] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single terminal. Accordingly, the (absolute time) interval of time resources (e.g., subframes, slots, or transmit time intervals (TTIs)) composed of the same number of symbols may be set differently between the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTIs, etc. may be referred to as time units.

[0059] For example, multiple numerologies, or SCSs, may be supported to support various services. For example, a 15 kHz SCS may support wide areas in traditional cellular bands, while a 30 kHz / 60 kHz SCS may support dense urban areas, lower latency, and wider carrier bandwidth. For example, a 60 kHz or higher SCS may support bandwidths greater than 24.25 GHz to overcome phase noise.

[0060] FIG. 4 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 4 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0061] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain, and may correspond to one numerology (e.g., SCS, CP length, etc.). For example, a carrier may include at most N BWPs (where N is a positive integer). For example, data communication may be performed through an activated BWP. For example, each element may be referred to as a resource element (RE) in the resource grid, and one complex symbol may be mapped to it.

[0062] For example, a BWP may be a contiguous set of PRBs in a given numerology. For example, a PRB may be selected from a contiguous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0063] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the UE may not monitor the downlink radio link quality in a DL BWP other than the active DL BWP on the PCell (primary cell). For example, the UE may not receive a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), or a channel state information-reference signal (CSI-RS) (except for radio resource management (RRM)) outside of the active DL BWP. For example, the UE may not trigger channel state information (CSI) reporting for an inactive DL BWP. For example, the UE may not transmit a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) outside of the active UL BWP. For example, for downlink, the initial BWP can be given as a set of consecutive resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For uplink, for example, the initial BWP can be given by the system information block (SIB) for the random access procedure. For example, the default BWP can be set by a higher layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if the terminal does not detect DCI (downlink control information) for a certain period of time, the terminal may switch its active BWP to a default BWP.

[0064] FIG. 5 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 5 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0065] Referring to FIG. 5, for example, a common resource block (CRB) may be a carrier resource block numbered from one end of a carrier band to the other, and a PRB may be a numbered resource block within each BWP. For example, point A may indicate a common reference point for a resource block grid.

[0066] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP ) can be set by. For example, point A can be an outer reference point of the PRB of a carrier where subcarrier 0 of all numerologies (e.g., all numerologies supported by the network on that carrier) aligns. For example, the offset can be the PRB spacing between the lowest subcarrier in a given numerology and point A. For example, the bandwidth can be the number of PRBs in a given numerology.

[0067] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to an embodiment of the present disclosure. The embodiment of FIG. 6 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0068] As core implementation technologies of the 6G system, technologies such as artificial intelligence (AI), THz (terahertz) communication, optical wireless technology, free-space optical transmission (FSO) backhaul networks, massive MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0069] - 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. For example, 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. AI can also 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.

[0070] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by using sub-THz communication with wide bandwidths 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 key part of the THz spectrum 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. Key characteristics of THz communications include (i) the widely available bandwidth to support very high data rates and (ii) the high path loss that occurs at high frequencies (requiring highly directional antennas). The narrow beamwidths generated by highly directional antennas reduce interference. The small wavelength of THz signals allows for a significantly 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.

[0084] Advanced Air Mobility (AAM): AAM can be a broad concept encompassing urban air mobility (UAM), regional air mobility (RAM), and uncrewed aerial systems (UAS). For example, AAM can include UAM, RAM, UAS, and uncrewed aerial vehicles (UAVs).

[0085] - 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) wireless communication and vehicle to infrastructure (V2I) wireless communication.

[0086] Non-terrestrial network (NTN): NTN can refer to a network or network segment that utilizes radio frequency (RF) resources mounted on satellites (or UAS platforms). NTN services may be considered to secure wider coverage or provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0087] - Integrated sensing and communication (ISAC)

[0088] - Reconfigurable intelligent surface (RIS): RIS can be used to manipulate and enhance signal propagation in wireless communication environments. For example, a RIS can be composed of many small antennas, or metasurfaces, arranged on a surface, each of which can actively control the phase, amplitude, polarization, etc. of the reflected signal. For example, a RIS can improve signal reception by controlling the path, phase, and / or intensity of the propagating signal. For example, in the case of a RIS, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For example, because a RIS can be reconfigured to suit different environments, it can meet diverse communication requirements and operate effectively in dynamic network environments.

[0090] Referring to FIG. 7, NTN communication can be performed based on satellite networks, high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS), and terminals capable of aerial communication (e.g., AAMs). For example, to improve coverage, etc., devices such as satellite networks, HIBS, and terminals capable of aerial communication (e.g., AAMs) can act as relays. For example, an AAM can communicate with a base station, a satellite network, etc., and / or an AAM can communicate directly with a terminal, another AAM, etc.

[0091] Below, the integrated sensing and communication (ISAC) mentioned above is described in detail.

[0092] Integrated Sensing and Communications (ISAC) 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 environment and / or the characteristics of objects within the environment. Because radio frequency sensing does not require a device to connect to the object through a network, it can provide services 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., unmanned aerial vehicles, 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 a wireless sensing service (e.g., sensing operation) may depend on the transmission, reflection, and scattering processing of wireless sensing signals. Therefore, wireless sensing may provide an opportunity to enhance existing communication systems from communication networks to wireless communication and sensing networks. FIG. 8 illustrates an example of a sensing operation according to an embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. Specifically, FIG. 8 (a) illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and FIG. 8 (b) illustrates an example of sensing using a separated sensing receiver and a sensing transmitter (e.g., bistatic sensing).

[0108] In the present disclosure, the TRP and the base station may be replaced and used as the same entity.

[0109] In the present disclosure, the sensing signal and the sensing RS (reference signal) can be interpreted and used interchangeably.

[0110] In the embodiments of the present disclosure, “a specific threshold” may mean a threshold defined in advance or set (in advance) by a network or a base station or a higher layer of a terminal (e.g., including an application layer).

[0111] In the embodiments of the present disclosure, “specific setting value” may mean a value defined in advance or set (in advance) by a network or a base station or a higher layer of a terminal (e.g., including an application layer).

[0112] In the embodiments of the present disclosure, “configured by the network / base station” may mean an operation in which the base station configures (in advance) the UE via higher layer signaling (e.g., RRC signaling), configures / signals the UE via MAC CE, or signals the UE via DCI (downlink control information).

[0113] In embodiments of the present disclosure, “message” may be interpreted as being replaced with a control message or a data message or a signal or a data signal or a control signal.

[0114] Meanwhile, a sensing data transmitter (hereinafter, transmitter) can transmit collected sensing data to a sensing data receiver (hereinafter, receiver).

[0115] For example, the transmitter may be an entity that measures / collects sensing data and transmits it to a receiver. Typically, for example, the transmitter may be a sensing signal receiver, such as a UE or a TRP (e.g., a BS). Furthermore, for example, in a service exposure operation, a sensing server may become a transmitter and transmit sensing data to a third-party server.

[0116] Alternatively, for example, the receiver may be an entity that receives sensing data transmitted by the sender. Typically, for example, the receiver may be a sensing server, and the sensing server may be located on a base station, a UE, or a core network. Furthermore, for example, in a service exposure operation, a third-party server may be the receiver that receives the sensing data transmitted by the sensing server.

[0117] Meanwhile, the procedure and method for the transmitter to collect and transmit sensing data may be as follows.

[0118] For example, a "sampling period" for collecting sensing data and a "reporting period" for transmission can be set by default. For example, a transmitter can measure / collect sensing data according to the set sampling period and transmit the collected sensing data to the receiver according to the set reporting period.

[0119] Additionally, for example, to improve transmission efficiency, a specific "threshold" can be set, and sensing data can be measured / collected and / or transmitted only when the value is above or below that threshold. For example, if the difference between the previous and current sensing data values ​​does not meet a specific threshold condition, reporting can be skipped.

[0120] Meanwhile, the aforementioned "uniform" sampling / reporting cycle method can be performed without considering changes in the sensed data. Therefore, for example, even when the sensed data changes little or nothing, performing the sampling / reporting operation may result in unnecessary energy consumption (e.g., UE current consumption). For example, a threshold-based (e.g., threshold-based / event-triggered) sampling / reporting method can allow the transmitter to reduce unnecessary energy consumption by skipping unnecessary sampling and / or reporting.

[0121] For example, the above "sampling period" may mean a period (e.g., a time interval) for measuring a sensing signal / collecting sensing data. On the other hand, for example, when using the threshold method described above, the threshold may not be used as a period for measuring a sensing signal, but as a unit for collecting / storing sensing data. For example, in order to omit sampling / reporting using such a threshold, the sensing signal must first be measured, and it must be confirmed whether the measured sensing signal satisfies the threshold condition. For example, the presence or absence of a sampling / reporting operation can be determined by determining the amount of change in the sensing data. Therefore, for example, regardless of the threshold setting, the transmitter must measure the sensing signal (e.g., receive / measure the sensing signal) according to a specific period. Thereafter, for example, by comparing it with the set threshold, a sampling operation (e.g., collecting / storing sensing data) and a transmission operation (e.g., transmitting sensing data) can be performed.

[0122] Finally, for example, sampling / reporting methods using thresholds may require periodic sensing signal measurements to determine whether a threshold condition is met, which may result in unnecessary energy / current consumption when sampling and / or reporting is not performed.

[0123] In summary, according to the prior art, the sampling operation of the sensing signal and / or the reporting operation of the sensing data were performed based on a threshold condition, but the measurement operation of the sensing signal (e.g., transmitting and receiving the sensing signal in the case of monostatic sensing or receiving the sensing signal in the case of bistatic sensing) that must be performed in advance for the sampling operation and the reporting operation was not performed based on a threshold, and the measurement of the sensing signal was performed based on a uniform cycle. In this case, the following problems may occur. For example, even when the change in the sensing signal is almost negligible or negligibly small, unnecessary processing or power consumption may occur because the measurement of the sensing signal is repeatedly performed based on a uniform cycle. Or, for example, even when the change in the sensing signal occurs rapidly, if the measurement is performed based on a uniform cycle, the performance of the detection related to the change may be lowered, or a delay may occur in sampling and / or reporting.

[0124] In this disclosure, a method for measuring non-uniformity of a sensing signal and a device supporting the same are proposed.

[0125] For example, if the sensing target changes gradually or the change is not large, the "sensing signal measurement cycle" can be gradually changed (e.g., gradually increasing or decreasing the cycle) to reduce the current consumption due to sensing. For example, if no significant change is detected even after n measurements, the next measurement cycle can be increased to reduce current consumption and signaling overhead. For example, in the opposite case (e.g., if the change in the sensing target is detected to be gradually increasing), the next measurement cycle can be decreased to improve sensing performance.

[0126] For example, if the difference in the sensing signal value occurs to be less than a threshold (e.g., if the change is small or almost non-existent), the "sensing signal measurement period" can be gradually increased to reduce the signaling overhead of the transmitter and improve the current consumption performance.

[0127] Additionally, for example, when the difference in sensing signal values ​​is greater than a threshold (e.g., when a large change occurs), the sensing performance can be improved by gradually reducing the “sensing signal measurement period.”

[0128] For example, rather than uniformly measuring the "sensing signal measurement period", the period can be adjusted non-uniformly (e.g., gradually increased / decreased) according to the change (amount) of the sensing signal value.

[0129] Hereinafter, example(s) related to the above description may be as follows.

[0130] Method 1. Gradual change in the "sensing signal measurement cycle" (gradual increase or decrease in cycle)

[0131] For example, the sensing signal measurement cycle may be gradually changed based on changes in the measured sensing signal value. For example, a method for setting the "sensing signal measurement cycle" for gradual change may be as follows.

[0132] Method 1-1. When using a single multiple value (e.g., M value)

[0133] For example, when using a multiple value (hereinafter, a multiple value is assumed as M), if there is no change above / below a threshold value for a certain period of time (e.g., this value may be a configurable value), the “sensing signal measurement period” can be increased / decreased by M times. In addition, for example, the “sensing signal measurement period” increased / decreased by M times can be changed back to a period increased / decreased by M times the current value if there is no change above / below a threshold value for a certain period of time (e.g., this value may be a configurable value). In this case, for example, it can have a value increased / decreased by 2M times the initially set sampling / reporting period value.

[0134] FIG. 9 illustrates a method for gradually changing a sensing signal measurement cycle using a multiplier value, according to one embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0135] Referring to Fig. 9, assuming a multiplier value (e.g., M value) as 2, sensing sampling / reporting can be performed at n-hour intervals for x times (or x hours), and if there is no change in sensing data during that time (e.g., for x times (or x hours)), sensing sampling / reporting can be performed at 2n-hour intervals (e.g., n times doubled). For example, if there is no change in sensing data for y times (or y hours), sensing sampling / reporting can be performed at 4n-hour intervals (e.g., 2n times doubled). In this case, for example, the x-value and the y-value can be the same value or different values.

[0136] Method 1-2. When using multiple multiple values ​​(e.g., array)

[0137] For example, multiple multiples can be represented as an array. For example, if {n, n, n, 2n, 2n, 2n, 2n, 3n, 3n, 3n, 3n, 3n}; n=10ms;, the first 3 can be performed at 10ms intervals. And, for example, the next 4 can be performed at 20ms intervals. And, for example, the next 5 can be performed at 30ms intervals. For example, this can be concisely expressed as {n, 3, 2n, 4, 3n, 5}; n=10ms; For example, if 30ms is the maximum interval, it can be expressed as {n, 3, 2n, 4, 3n, Inf}; (where "Inf" can mean infinite).

[0138] Method 1-3. When using "time units" (e.g., when using a single n-hour value)

[0139] For example, if the period change value is assumed to be 10 seconds, if there is no change above / below the threshold value for a certain period of time (e.g., this value may be a configurable value), the "sensing signal measurement period" value can be increased / decreased by 10 seconds. For example, the "sensing signal measurement period" increased / decreased by 10 seconds can be changed to a period increased / decreased by 10 seconds (or an arbitrarily set value such as 20 seconds) again if there is no change above / below the threshold value for a certain period of time (e.g., this value may be a configurable value). In this case, for example, it can have a value increased / decreased by 20 seconds from the initially set sampling / reporting period value.

[0140] Method 1-4. When using multiple time units (e.g., arrays)

[0141] For example, similar to the method 1-2 described above, it can be set as an array value having multiple time unit values.

[0142] In the present disclosure, the minimum and / or maximum values ​​of the changing cycle may be set as follows.

[0143] For example, as described above, the periodic change operation can continuously increase / decrease. For example, in the case of the maximum value, it can be set to an infinite value (e.g., "Inf" as described above). Or, for example, it can be set to a finite value.

[0144] For example, if the value has a finite value, the "sensing signal measurement period" value that is changed can be changed within the minimum and / or maximum values.

[0145] For example, if the value you are trying to change exceeds the minimum and / or maximum values, the period change may no longer occur, and the current value or the minimum / maximum values ​​may be used.

[0146] In this case, for example, a cycle minimum and / or maximum value can be set. For example, the cycle minimum and maximum values ​​can be a specific time value or a specific multiple value. For example, 1ms, 10ms, 1sec, 10min, etc. can be set as a specific time value. Or, for example, it can be set as a specific multiple value such as / 4x, / 8x, x4x, x8x, etc.

[0147] Additionally, for example, after x "sensing signal measurement cycles" of the maximum value, there may be an option for the period value to decrease as well as remain at the maximum value. For example, in the latter case, the value of x may be set to a relatively larger value compared to the case where the period value increases, and furthermore, there may be a separate lower bound (e.g., a value in the middle rank of candidate period values) on the period values ​​that can decrease in descending order. In this case, for example, the disadvantage of a large period value as described above may be similarly compensated for.

[0148] In the present disclosure, the comparison of changes (amounts) above / below a threshold value may be as follows.

[0149] For example, the current measurement value can be compared with the previous measurement value, and a change in the period can be considered if the change (amount) is above / below a threshold value.

[0150] Alternatively, for example, when counting samplings that have a change greater than a threshold level within a specific period, the reference for this change may be set to one of the average, median, minimum, or maximum values ​​of the samplings within the previous period (rather than the immediately previous measurement).

[0151] Alternatively, for example, if there is a change in the state of the transmitter (e.g., position / angle of the transmitter, etc.) in a particular cycle compared to the previous cycle, a pre-set default value (rather than the immediately previous measurement) can be used as a reference.

[0152] Method 2. Change and return to a specific cycle (e.g., fallback / reset)

[0153] For example, gradual changes to the "sensing signal measurement cycle" can mitigate problems that can arise when the cycle is suddenly and significantly changed. However, changes to a specific cycle or to the default value may also be possible, for example, depending on the sensing situation.

[0154] For example, if there is a change greater than a critical level in the sensing signal measurement value performed at any point during x measurements compared to the previous time (e.g., due to a sudden increase in the number of objects or a change in the environment), it may also be possible to immediately change to the minimum value of the "sensing signal measurement cycle." For example, this method can compensate for the disadvantage of not being able to quickly respond to a sudden change in an object or environment by changing the cycle after performing X operations when the "sensing signal measurement cycle" value reaches a large cycle value.

[0155] Alternatively, for example, if the transmitter's position / angle, etc., changes beyond a certain level or a significant change in the environment is detected, the changed period value can be set to fallback to a preset value (e.g., a default value) or reset to the value before the period change started.

[0156] In the present disclosure, the relationship between the “sensing signal measurement period” and the “sensing data collection / transmission period” may be as follows.

[0157] For example, the “sensing signal measurement period” and the “sensing data collection / transmission period” may be related to each other, and a change in the “sensing signal measurement period” may also cause a change in the sensing data collection (e.g., sampling) and / or transmission (e.g., reporting) period.

[0158] For example, if the “sensing signal measurement period” becomes longer, the sensing data collection (e.g., sampling) and / or transmission (e.g., reporting) period may also become correspondingly longer.

[0159] For example, in the opposite case, if the “sensing signal measurement period” is shortened, the sensing data collection (e.g., sampling) and / or transmission (e.g., reporting) period may also be shortened accordingly.

[0160] Alternatively, for example, the "sensing signal measurement period" and the "sensing data collection / transmission period" may be performed separately. For example, in the case of an object shape detection service, if a change in the sampling value for a target object exceeds a threshold level, the reporting period may not be changed, and only the "sensing signal measurement period" value may be relatively adjusted to a smaller value. Or, for example, in the case of an object distance measurement service, if the number of objects increases to a threshold level or more, the "sensing signal measurement period" value may not be changed, and the reporting period value may be relatively adjusted to a smaller value.

[0161] In the present disclosure, the sender can notify the receiver of the changed period as follows.

[0162] For example, the transmitter can notify the receiver of a changed "sensing signal measurement period" value. For example, since sensing data collection / storage and transmission operations are performed according to the "sensing signal measurement period," the changed period value may affect the operation of the receiver for receiving sensing data (e.g., affecting the receiver's current consumption). Therefore, for example, the transmitter can notify the receiver of a changed "sensing signal measurement period" value. In this case, for example, the transmitter can notify the changed value of the sensing signal sampling / reporting period. For example, the receiver can utilize this value to expect reception of sensing data at a specific period.

[0163] Alternatively, for example, the sender could inform the receiver not only of the changed period value but also which transmission of the current report is the corresponding period value. For example, the receiver may fail to receive the report transmitted by the sender, and in this case, knowing this latter information could reduce the number of useless reception operations.

[0164] Alternatively, the transmitter may not inform the receiver of the changed "sensing signal measurement period" value. For example, signaling to inform the receiver of the changed "sensing signal measurement period" value may also increase signaling overhead, and if a transition to an RRC connection is required to transmit it, power consumption may increase. Therefore, for example, if both the transmitter and receiver can recognize the set value, the transmitter does not need to inform the changed period value. Alternatively, for example, in some cases, the receiver may request the information from the transmitter, receive a response, and operate according to the changed period.

[0165] In the present disclosure, settings and operations according to RRC states can be distinguished as follows.

[0166] For example, the change in the "sensing signal measurement period" may be processed differently depending on the state of the transmitter or receiver. For example, the transmitter may perform the "sensing signal measurement period" change operation in the RRC idle or inactive state. Conversely, for example, the transmitter may not perform the "sensing signal measurement period" change operation in the RRC connected state. In this case, for example, the transmitter may increase the power consumption performance in the RRC idle or inactive state, and conversely, increase the sensing performance in the RRC connected state.

[0167] In the present disclosure, signaling of parameter settings may be as follows.

[0168] For example, various parameters for changing the "sensing signal measurement period" of the sender (e.g., reference sensing parameters, thresholds, period change values, maximum / minimum change values, period change indications, etc.) can be set by the receiver, a sensing server, or a third-party server. Or, for example, they can be set by the sender. Or, for example, values ​​defined in a standard document can be used.

[0169] For example, when the above parameters are set through signaling, it may be possible through various protocol signaling such as LPP (LTE positioning protocol), SLPP (sidelink positioning protocol), NAS (non-access stratum), RRC (radio resource control), MAC (medium access control) CE (control element), physical control (e.g., DCI (downlink control information) or SCI (sidelink control information)), or sensing protocol.

[0170] For example, parameters for changing the "sensing signal measurement cycle" can be set independently or dependently from parameters related to sensing data sampling / reporting. For example, the changed "sensing signal measurement cycle" can be applied to sampling operations and / or reporting operations. Alternatively, sampling and reporting can be set separately.

[0171] For example, parameter settings can be set differently for each sensing service. For example, if a sensing session is created for a sensing service, parameter settings can be set differently for each sensing session. For example, parameter settings can be set differently for each sensor (within a single session).

[0172] In the present disclosure, the sensing signal value and threshold value may be as follows.

[0173] For example, sensing signal values ​​may vary depending on the type / purpose of the sensing service. For example, they may include at least one of the following:

[0174] - Distance of the sensed object

[0175] - AoA (Angle of Arrival) of the sensed object

[0176] - ToA (Timing of Arrival) of the sensed object

[0177] - Doppler or speed of the sensed object

[0178] - RSRP (reference signal received power) of sensing signal

[0179] - CSI (channel state information) of sensing signal

[0180] - Appearance or disappearance of a new object

[0181] - Change in the total number of objects

[0182] - Surrounding environmental values ​​of the sensed environment (e.g., rainfall for flood detection)

[0183] - Changes in sensing areas (e.g., target sensing service area (TSSA))

[0184] - Change in state of the transmitter (or sensing receiver) (e.g. speed, direction, etc.)

[0185] - Other sensing parameters

[0186] For example, the threshold of the sensing signal can be set based on the above-described sensing signal value.

[0187] For example, if the purpose of the service is to measure the distance to an object, the threshold value can be expressed as a specific distance value from the sensed object.

[0188] For example, if the purpose of the service is to measure changes in the number of objects, the threshold can be expressed as the number of sensed objects.

[0189] For example, if the service objective is to detect changes in the surrounding environment (e.g., environment sensing), the amount of environmental change can serve as a threshold. For example, in the case of a precipitation measurement service using a non-terrestrial network (NTN), a specific amount of precipitation change can be set as the threshold and monitoring can be performed. For example, if monitoring results show that there is little change in precipitation, the sensing operation time can be gradually increased to prevent energy consumption due to unnecessary sensing operations.

[0190] For example, it may be possible to change the "sensing signal measurement cycle" based on changes in the transmitter's status. For example, if the transmitter is largely motionless, the sensing operation time can be gradually increased to prevent energy consumption due to unnecessary sensing operations.

[0191] FIG. 10 illustrates a method for non-uniformly changing the measurement period of a sensing signal according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0192] Referring to FIG. 10, a UE (or a base station (BS)) may be a device that performs monostatic sensing for a target (or a target sensing area). For example, the UE may transmit at least one sensing signal based on at least one measurement period, and may receive a signal reflected from the target by the at least one sensing signal. For example, the UE may perform sensing / measurement on at least one sensing signal received within the at least one measurement period based on at least one sampling period associated with the at least one measurement period, and may generate sensing data based thereon. For example, the UE may transmit / report the sensing data to a base station or a sensing management function (SMF) (or a sensing function (SF)) based on at least one reporting period associated with the at least one measurement period.

[0193] In step S1010, the UE (or BS (base station)) can transmit and receive a first sensing signal based on a first measurement period. In step S1020, the UE (or BS (base station)) can transmit and receive a second sensing signal based on the first measurement period. For example, the first sensing signal can be measured based on the nth measurement period among the first measurement periods, and the second sensing signal can be measured based on the (n+1)th measurement period among the first measurement periods.

[0194] In step S1030, the UE (or BS (base station)) can compare the amount of change and the threshold value between the value related to the first sensing signal and the value related to the second sensing signal. Specifically, for example, when the UE (or BS (base station)) obtains configuration information for changing the measurement period related to the sensing signal, the UE (or BS (base station)) can measure the values ​​of each of the first sensing signal and the second sensing signal based on a sensing parameter among a plurality of sensing parameters included in the configuration information (e.g., distance to the target, AoA (angle of arrival) with the target, ToA (time of arrival) with the target, speed of the target, number of targets, RSRP (reference signal received power) of the sensing signal, CSI (channel state information) of the sensing signal, etc.), and determine whether to obtain the amount of change. For example, the sensing parameter can be determined based on a sensing service provided by the UE (or BS (base station)). In addition, for example, the threshold value may be determined based on the determined sensing parameter. For example, when the sensing parameter is determined as RSRP, the UE (or BS (base station)) may measure a first RSRP value related to the first sensing signal and a second RSRP value related to the second sensing signal, respectively, and may obtain a change amount between the first RSRP value and the second RSRP value. And, for example, the UE (or BS (base station)) may determine, based on a threshold value related to RSRP, whether the change amount is greater than the threshold value or less than the threshold value.

[0195] In step S1040, the UE (or BS (base station)) may change the first measurement period to a second measurement period. For example, if the amount of change is greater than a threshold value, the UE (or BS (base station)) may determine that a lot of changes related to the target have occurred, and therefore, the UE (or BS (base station)) may change the first measurement period to a shorter measurement period than the first measurement period in order to improve sensing performance. In this case, for example, the second measurement period may be a measurement period that is reduced by M times the first measurement period. For example, M may be a fixed value of one integer. Or, for example, M may be a value that is sequentially applied in an array including a plurality of integers that are gradually increased / decreased. Or, for example, the second measurement period may be a measurement period that is reduced by N time units from the first measurement period. For example, N may be a fixed value of one integer. Alternatively, for example, N may be a value sequentially applied from an array containing multiple integers that gradually increase / decrease. Alternatively, for example, the time unit may be seconds or milliseconds. Meanwhile, although the embodiment of FIG. 10 illustrates an operation in which the measurement cycle is changed once for convenience of explanation, the above-described operation may be repeatedly performed, and thus the measurement cycle of the sensing signal may be gradually increased / decreased. In addition, for example, the second measurement cycle changed from the first measurement cycle may be changed within a range between a maximum value and a minimum value. For example, when the second measurement cycle exceeds the maximum value or the minimum value, it may be maintained (e.g., reset) as the first measurement cycle, or maintained as the measurement cycle of the maximum value, or maintained as the measurement cycle of the minimum value.For example, if the measurement cycle of the maximum value or the measurement cycle of the minimum value is maintained for a certain period of time, it may be reset to a (pre-)set measurement cycle. Or, for example, if the level at which the measurement cycle changes from the first measurement cycle to the second measurement cycle exceeds a threshold level (e.g., if the measurement cycle is not changed gradually), the second measurement cycle may be changed to a (pre-)set measurement cycle or a default measurement cycle.

[0196] In step S1050, the UE (or BS (base station)) can transmit and receive a third sensing signal based on the second measurement period. In step S1060, the UE (or BS (base station)) can report sensing data generated based on the third sensing signal to the base station or the SMF. Meanwhile, for example, a sampling period for generating sensing data or a reporting period for reporting sensing data can be set in relation to the measurement period of the sensing signal. Therefore, for example, a sampling period or a reporting period related to the third sensing signal can be different from a sampling period or a reporting period related to the first sensing signal or the second sensing signal. For example, the UE (or BS (base station)) can report information related to a second measurement period (e.g., a changed measurement period) to the base station or the SMF in order to receive sensing data generated based on the third signal of the base station or the SMF.

[0197] FIG. 11 illustrates a method for a first device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0198] Referring to FIG. 11, in step S1010, the first device can obtain setting information for changing a measurement cycle associated with at least one sensing signal. In step S1020, the first device can obtain a value associated with the at least one sensing signal based on the measurement cycle. In step S1030, the first device can change the measurement cycle based on a change amount and a threshold value of a value associated with the at least one sensing signal.

[0199] For example, based on the change being less than the threshold value, the measurement cycle may be changed to a measurement cycle longer than the measurement cycle. For example, the longer measurement cycle may be at least one of a measurement cycle increased by M times the measurement cycle or a measurement cycle increased by N time values ​​of the measurement cycle. For example, M or N may be an integer greater than 1.

[0200] For example, based on the change being greater than the threshold value, the measurement cycle may be changed to a shorter measurement cycle than the measurement cycle. For example, the shorter measurement cycle may be at least one of a measurement cycle reduced by M times the measurement cycle or a measurement cycle reduced by N time values ​​of the measurement cycle. For example, M or N may be an integer greater than 1.

[0201] For example, the amount of change may be obtained based on a difference between a value associated with a first sensing signal and a value associated with a second sensing signal, which are obtained based on the measurement period among the at least one sensing signal.

[0202] For example, the change may be based on at least one of a difference in reference signal received power (RSRP) or a difference in channel state information (CSI) for each of the first sensing signal and the second sensing signal among the at least one sensing signal.

[0203] For example, the change may be based on at least one of a difference in distance relative to a target object measured based on each of the first sensing signal and the second sensing signal among the at least one sensing signal, a difference in angle of arrival (AoA), a difference in time of arrival (ToA), a difference in speed, or a difference in number.

[0204] For example, based on the change in the measurement period, at least one of a sampling period associated with the at least one sensing signal or a reporting period associated with the at least one sensing signal may be changed.

[0205] For example, information related to a measurement period changed from the above measurement period may be transmitted to a device that receives sensing data generated based on the at least one sensing signal.

[0206] For example, based on the measurement cycle changed from the above measurement cycle exceeding a threshold level, the changed measurement cycle can be initialized to the above measurement cycle.

[0207] For example, whether to change the measurement cycle may be based on the RRC (radio resource control) status of the first device.

[0208] For example, the setting information may include information related to at least one of a sensing parameter associated with the at least one sensing signal, a value for changing the measurement period, a maximum value of the change, a minimum value of the change, or a threshold value.

[0209] The proposed method can be applied to devices according to various embodiments of the present disclosure. First, the processor (102) of the first device (100) can control the transceiver (106) to obtain setting information for changing a measurement period related to at least one sensing signal. Then, the processor (102) of the first device (100) can control the transceiver (106) to obtain a value related to the at least one sensing signal based on the measurement period. Then, the processor (102) of the first device (100) can change the measurement period based on the amount of change and the threshold value of the value related to the at least one sensing signal.

For example, the instructions, based on execution by the at least one processor, may cause the first device to: obtain configuration information for changing a measurement period associated with at least one sensing signal; obtain a value associated with the at least one sensing signal based on the measurement period; and change the measurement period based on a change amount and a threshold value of the value associated with the at least one sensing signal.

[0211] According to one embodiment of the present disclosure, a processing device configured to control a first device may be provided. For example, the processing device may include at least one processor; and at least one memory coupled to the at least one processor and storing instructions.

The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0214] Referring to FIG. 12, in step S1210, the second device may receive first sensing data from the first device based on a reporting cycle. In step S1220, the second device may receive, from the first device, information related to a reporting cycle changed from the reporting cycle. In step S1230, the second device may receive second sensing data from the first device based on the changed reporting cycle. For example, the changed reporting cycle may be determined based on a threshold value and a change amount of a value of at least one sensing signal acquired in a measurement cycle related to the reporting cycle.

[0215] The proposed method can be applied to devices according to various embodiments of the present disclosure. First, the processor (202) of the second device (200) can control the transceiver (206) to receive first sensing data from the first device based on a reporting cycle. Then, the processor (202) of the second device (200) can control the transceiver (206) to receive, from the first device, information related to a reporting cycle changed from the reporting cycle. Then, the processor (202) of the second device (200) can control the transceiver (206) to receive second sensing data from the first device based on the changed reporting cycle. For example, the changed reporting cycle can be determined based on a threshold and a change amount of a value of at least one sensing signal acquired in a measurement cycle related to the reporting cycle.

[0216] According to one embodiment of the present disclosure, a second device configured to perform wireless communication may be provided. For example, the second device may include at least one transceiver; at least one processor; and at least one memory coupled to the at least one processor and storing instructions. For example, the instructions, based on execution by the at least one processor, may cause the second device to: receive, from a first device, first sensing data based on a reporting period; receive, from the first device, information related to a reporting period changed from the reporting period; and receive, from the first device, second sensing data based on the changed reporting period.

For example, the changed reporting cycle may be determined based on a threshold value and a change in a value of at least one sensing signal acquired in a measurement cycle related to the reporting cycle.

[0219] According to various embodiments of the present disclosure, the transmitter can operate the "sensing signal measurement cycle" in a non-uniform cycle manner. This allows, for example, when the object in the sensing area and / or the surrounding environment do not change significantly (e.g., in a stable / static environment), signaling overhead can be reduced and power consumption performance can be improved by gradually increasing the cycle. Furthermore, for example, when the object in the sensing area and / or the surrounding environment change significantly (e.g., in an unstable / dynamic environment), sensing performance can be improved by gradually decreasing the cycle.

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.

[0243] 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.

[0244] 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. 15. For example, a wireless device (e.g., 100, 200 of FIG. 14) 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. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
