[0044] 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.
[0045] 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).
[0046] 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.
[0047] 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).
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] 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).
[0055] 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.
[0056] 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.
[0057] 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.
[0058] 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).
[0059] 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.
[0060] 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).
[0061] 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).
[0062] 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.
[0063] 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
[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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 a 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.
[0070] 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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] - 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.
[0076] - 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.

[0090] 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).
[0091] - 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.
[0092] 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.
[0093] - Integrated sensing and communication (ISAC)
[0094] - 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.
[0095] FIG. 7 illustrates an example of a communication scenario based on a 6G system, according to an embodiment of the present disclosure. The embodiment of FIG. 7 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.
[0096] 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.
[0097] Below, the integrated sensing and communication (ISAC) mentioned above is described in detail.
[0098] 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).
[0099] The meanings of terms used in this disclosure may be as follows.
[0100] - ISAC: Integrated Sensing and Communication
[0101] - Sensing signal: A reference signal transmitted and received for sensing.
[0102] - Sensing transmitter (Tx: entity that transmits sensing signals)
[0103] - Sensing receiver (sensing Rx(receiver)): an entity that receives a sensing signal
[0104] - Monostatic sensing: Sensing in which the sensing transmitter and sensing receiver are co-located in the same TRP or UE.
[0105] - Bi-static sensing: Sensing in which the sensing transmitter and the sensing receiver are located in different TRPs or UEs.
[0106] - Multi-static sensing: Sensing with multiple sensing transmitters and / or multiple sensing receivers for the sensing target.

[0108] - Environment object (EO): An object whose location is known other than the target object.
[0109] - Clutter: Background or objects whose location cannot be specified, excluding the target object and environment object.
[0110] - Sensing RS (reference signal): Reference signal used for measurement for sensing purposes
[0111] - BS-BS sensing: Sensing in which BS#1 transmits a sensing RS and BS#2 receives the sensing RS. For example, if BS#1 and BS#2 are separate BSs, this may mean a BS-BS bi-static sensing operation. For example, if BS#1 and BS#2 are the same BS, this may mean a BS-BS mono-static sensing operation. For example, the BS may be a base station or a transmission and reception point (TRP). For example, if BS#1 and / or BS#2 are one or more BSs, this may mean a BS-BS multi-static sensing operation.
[0112] - BS-UE sensing: Sensing in which a BS transmits a sensing RS and a UE receives the sensing RS. For example, the BS may be a base station or a transmission and reception point (TRP). For example, if the BS and / or the UE are one or more BSs and / or one or more UEs, this may refer to a BS-UE multi-static sensing operation.
[0113] - UE-BS sensing: Sensing in which a UE transmits a sensing RS and a BS receives the sensing RS. For example, the BS may be a base station or a transmission and reception point (TRP).

[0114] - UE-UE sensing: Sensing in which UE#1 transmits a sensing RS and UE#2 receives the sensing RS. For example, if UE#1 and UE#2 are separate UEs, this may mean a UE-UE bi-static sensing operation. For example, if UE#1 and UE#2 are the same UE, this may mean a UE-UE mono-static sensing operation. For example, the BS may be a base station or a transmission and reception point (TRP). For example, if UE#1 and / or UE#2 are one or more UEs, this may mean a UE-UE multi-static sensing operation.
[0115] - SMF: Sensing Management Function
[0116] - TSA: Target Sensing Area
[0117] Meanwhile, in conventional communications (e.g., NR Uu or NR sidelink), the sensing procedure of a device (e.g., a terminal or a base station) was not considered a service. However, since the main purpose of the ISAC service is to quickly detect and distinguish a target object through sensing, it is necessary to classify the sensing procedure (or operation) as a service that must satisfy one QoS requirement (e.g., sensing latency: the time it takes for a terminal that triggers sensing to trigger the sensing procedure and for a receiving terminal to receive the sensing result of the target object, or sensing accuracy, etc.). For example, in ISAC, the sensing behavior of a device (e.g., a terminal or a base station or a sensing management function (SMF)) can be considered a service that must satisfy the ISAC sensing QoS requirement, and the terminal can perform a sensing operation (e.g., transmitting a sensing reference signal and / or receiving a sensing reference signal) based on the sensing QoS.
[0118] For example, sensing in ISAC can be considered as a higher layer service that must satisfy sensing QoS (or sensing quality) based on sensing results, and a new QoS (e.g., Sensing QoS Flow ID (SQFI)) for the ISAC sensing service can be defined as follows.
[0119] - SQFI (Sensing QoS Flow ID)
[0120] - SQFI 1 ~ 8: For example, they can be distinguished according to the level of sensing QoS requirements. For example, sensing QoS requirements can include sensing accuracy, sensing latency (e.g., latency boundary from sensing triggering to receiving sensing results), or sensing priority (e.g., priority that can be used to determine which sensing service is triggered first based on priority when multiple sensing procedures are required). For example, a sensing service with a smaller (or higher) SQFI value can be defined as having a tighter QoS requirement (e.g., a sensing service requiring high sensing accuracy, or a sensing service requiring low / lower / lowest sensing latency).
[0121] Additionally, ISAC defines terminal and TRP (or base station) operations to support sensing services such as detection, localization, and tracking.
[0122] For example, the sensing QoS for ISAC services (detection, localization, tracking, etc.) could be as follows:
[0123] - Detection QoS: detection probability, false alarm probability
[0124] - Localization QoS: localization of the static objects, QoS parameters of localization (e.g., time delay, angle of arrival)
[0125] - Tracking QoS: Tracking the status changes of moving targets (e.g., vehicles or drones) (range, angle, velocity, etc.)
[0126] FIG. 9 illustrates a support scenario for sensing services in an ISAC, according to an 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.
[0127] Referring to Fig. 9, the six main sensing modes are as follows. Specifically, Fig. 9 (a) shows gNB mono-static. In this case, the same gNB can perform both Tx and Rx roles. Fig. 9 (b) shows gNB bi-static. In this case, one gNB can perform the Tx role and the other gNB can perform the Rx role. Fig. 9 (c) shows gNB-to-UE bi-static. In this case, the gNB can perform the Tx role and the UE can perform the Rx role. Fig. 9 (d) shows UE-to-gNB bi-static. In this case, the UE can perform the Tx role and the gNB can perform the Rx role. Fig. 9 (e) shows UE mono-static. In this case, the same UE can perform both Tx and Rx roles. Figure 9 (f) shows a UE bi-static. In this case, one UE can perform the Tx role and another UE can perform the Rx role.
[0128] Meanwhile, in existing 5G systems, sensing services were not defined as a separate QoS model from communication traffic. In this case, the following problems may arise. For example, sensing traffic may be larger or have a higher traffic load than communication traffic. Therefore, if sensing traffic is mapped to the same data radio bearer (DRB) as communication traffic, the sensing traffic may excessively occupy the DRB resources, which may increase delays in communication traffic. Alternatively, if sensing traffic is continuously transmitted in large quantities, the base station scheduler may face a high load in handling priority adjustments and resource allocation between communication and sensing traffic. Alternatively, if large volumes of sensing traffic are processed within the same QoS flow or PDU session as communication services, problems such as deterioration of communication service quality, unpredictable delays, and packet loss may occur.
[0129] In this disclosure, we propose an operation for mapping sensing QoS (quality of service) flows and DRB (data radio bearers) in ISAC.
[0130] As a background for the proposal of the present disclosure, the QoS model for conventional 5G communication services is as follows.
[0131] FIG. 10 illustrates a QoS model for a conventional 5G communication service 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.
[0132] Referring to FIG. 10, a QoS model (e.g., QoS flow to DRB mapping) for supporting communication services (e.g., uplink transmission, downlink transmission, uplink reception, downlink reception) in a conventional 5G system is illustrated. For example, a user plane function (UPF), which is an entity of a core network, can map service data flows (e.g., video, voice over internet protocol (VoIP), Best Effort, etc.) received from a data network (DN) to (each) QoS flow. And, for example, the UPF can configure one or more QoS flows into one PDU session. For example, a gNB (or an SDAP of the gNB) can map a QoS flow for service data received from the UPF to a DRB. At this time, for example, the gNB (or the SDAP of the gNB) can map one QoS flow to one DRB, or map multiple QoS flows to one DRB.
[0133] For example, in 6G ISAC, sensing services must be supported together with communication services, so new procedures may be required to map (sensing) QoS flows to sensing service data flows and / or to map sensing QoS flows to DRBs.
[0134] In this disclosure, we propose a new procedure for mapping sensing service data flows to sensing QoS flows and mapping sensing QoS flows to sensing DRBs, as follows.
[0135] Proposal 1. Mapping operation of sensing QoS flow and DRB based on sensing service QoS mode
[0136] Below, an embodiment of a 6G QoS model for supporting sensing services (e.g., transmission or reception) in 6G is shown.
[0137] In this disclosure, we propose a QoS model and procedure that enables a 6G core network entity to manage communication data flows (e.g., Best Effort, voice over internet protocol (VoIP), video, etc.) and sensing service data flows (e.g., sensing data) received from a data network (DN) as independent QoS flows.
[0138] FIG. 11 illustrates a QoS model for a 6G sensing service 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.
[0139] Referring to FIG. 11, a 6G core network entity can map sensing data received from a sensing function (SF), which is a network entity that manages sensing data (or, the sensing data can be received from a DN in the same way as communication data), to a sensing-only QoS flow separate from a communication data flow (e.g., Best Effort, voice over internet protocol (VoIP), video, etc.) received from a data network (DN). And, for example, the 6G core network entity can configure one or more sensing QoS flows into one PDU session (e.g., PDU session #1 of FIG. 11). In summary, for example, from a 6G core network entity for sensing, a service data flow (SDF) related to sensing can be mapped to one or more sensing QoS flows, and these one or more sensing QoS flows can be configured as a PDU session for sensing (e.g., PDU session #1 in FIG. 11). Meanwhile, for example, from a core network entity for communication (e.g., a core network entity separate from the 6G core network), a service data flow (SDF) related to communication can be mapped to one or more communication QoS flows, and these one or more communication QoS flows can be configured as a PDU session for communication (e.g., PDU session #2 in FIG. 11). For example, a base station (or an SDAP of the base station) can map a sensing QoS flow for sensing service data received from a 6G core network entity to a (sensing) DRB.At this time, for example, the base station (or the SDAP of the base station) can map one sensing QoS flow to one (sensing) DRB (e.g., DRB #1 or DRB #2 in FIG. 11), or map multiple sensing QoS flows to one (sensing) DRB. Meanwhile, for example, one communication QoS flow can be mapped to one (communication) DRB, or map multiple communication QoS flows to one (communication) DRB (e.g., DRB #3 in FIG. 11).
[0140] For example, so that a 6G core network entity can map a sensing service data flow to a sensing-dedicated QoS flow, a sensing function (SF) may provide the 6G core network entity with mapping configuration information between the sensing service data flow and the sensing QoS flow (e.g., QoS requirement information for each sensing service (e.g., latency, priority, reliability, accuracy, etc.), DRB information for the sensing service (e.g., the maximum number of sensing DRBs), sensing QoS flow ID information mapped to each sensing DRB), PDCP configuration information for the sensing service data (e.g., PDCP sequence number size information, out-of-delivery configuration (e.g., TRUE) information, etc.), RLC configuration information for the sensing service data (e.g., ACK mode / un-ACK mode configuration information, and mapping information between the QoS flow and DRB in Proposal 2 below). (mapping rules) can be passed.
[0141] In addition, for example, so that the base station (or the SDAP of the base station) can map the sensing QoS flow to the sensing DRB, the sensing function (SF) provides the base station with mapping configuration information between the sensing QoS flow and the sensing DRB (e.g., the mapped sensing QoS flow ID for each sensing service, the QoS requirement information for each sensing service (e.g., latency, priority, reliability, accuracy, etc.), the DRB information for the sensing service (e.g., the maximum number of sensing DRBs), the sensing QoS flow ID information mapped for each sensing DRB), the PDCP configuration information for the sensing service data (e.g., the size information of the PDCP sequence number, the out-of-delivery configuration (e.g., TRUE) information, etc.), the RLC configuration information for the sensing service data (e.g., the ACK mode / un-ACK mode configuration information, the mapping between the QoS flow and the DRB of Proposal 2 below). (rules) can be conveyed.For example, the base station can transmit to the UE mapping configuration information between the sensing QoS flow configured from the SF (sensing function) and the sensing DRB (e.g., the sensing QoS flow ID mapped to each sensing service, the QoS requirement information for each sensing service (e.g., latency, priority, reliability, accuracy, etc.), the DRB information for the sensing service (e.g., the maximum number of sensing DRBs), the sensing QoS flow ID information mapped to each sensing DRB), the PDCP configuration information for the sensing service data (e.g., the size information of the PDCP sequence number, the out-of-delivery configuration (e.g., TRUE) information, etc.), and the RLC configuration information for the sensing service data (e.g., the ACK mode / un-ACK mode configuration information, the mapping rule between the QoS flow and the DRB of Proposal 2 below).
[0142] In addition, for example, the sensing function (SF) may also transmit mapping configuration information between the sensing QoS flow and the sensing DRB directly to the UE (e.g., the sensing QoS flow ID mapped to each sensing service, the QoS requirement information for each sensing service (e.g., latency, priority, reliability, accuracy, etc.), the DRB information for the sensing service (e.g., the maximum number of sensing DRBs), the sensing QoS flow ID information mapped to each sensing DRB), the PDCP configuration information for the sensing service data (e.g., the size information of the PDCP sequence number, the out-of-delivery configuration (e.g., TRUE) information, etc.), and the RLC configuration information for the sensing service data (e.g., the ACK mode / un-ACK mode configuration information).
[0143] For example, through the 6G QoS model and / or the sensing service data flow to QoS flow mapping rule and / or the sensing QoS flow to sensing DRB mapping rule to support the proposed sensing service, the UE or the base station or the network entity can perform the following procedures.
[0144] For example, ISAC can establish independent PDU sessions for each communication service and sensing service.
[0145] For example, ISAC could establish independent DRBs for each of its communication services and sensing services.
[0146] For example, a QoS flow for a sensing service can be restricted from forming a PDU session with a QoS flow for a communication service. For example, the sensing service and the communication service can be managed as separate PDU sessions.
[0147] For example, a rule can be applied to map sensing QoS flows for a sensing service to a separate DRB than QoS flows for a communication service. For example, QoS flows for sensing and communication can be restricted from being configured into the same DRB.
[0148] For example, when sensing service data is transmitted from a sensing function (SF) to a UPF (e.g., a 6G core network entity) (e.g., a case where the sensing data is stored in the SF), the SF can transmit related settings (e.g., a sensing service data flow to QoS flow mapping rule, a sensing QoS flow to sensing DRB mapping rule) to the UPF (e.g., a 6G core network entity) and the base station so that the sensing data can be managed as a separate QoS flow. Alternatively, for example, when sensing service data is transmitted from a data network (DN) to a UPF (e.g., a 6G core network entity) like communication data (e.g., when the sensing data is transmitted over the Internet), the sensing function (SF) may transmit related settings (e.g., a sensing service data flow to QoS flow mapping rule, a sensing QoS flow to sensing DRB mapping rule) to the UPF (e.g., a 6G core network entity) and / or a base station so that the communication data (e.g., Best Effort, voice over internet protocol (VoIP), video, etc.) transmitted over the DN and the QoS flow and / or DRB of the sensing data can be independently managed.
[0149] Proposal 2. Mapping Rules between Sensing QoS Flows and DRBs
[0150] In this disclosure, we propose the following rules for mapping sensing service data QoS flows to DRBs.
[0151] FIG. 12 illustrates rules for mapping QoS flows related to sensing service data to DRBs, according to one embodiment of the present disclosure. 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.
[0152] Referring to FIG. 12, a sensing service data flow (e.g., PDU 1) may be configured as an independent PDU session from a communication data flow (e.g., PDU 2), and the sensing service data flow may be separately mapped to a sensing-only sensing QoS flow (e.g., QoS flow 1). Additionally, for example, the sensing QoS flow may be mapped to a separate DRB (e.g., DRB 1) from a communication DRB (e.g., DRB 2).
[0153] FIG. 13 illustrates rules for mapping QoS flows related to sensing service data to DRBs, according to one embodiment of the present disclosure. The embodiment of FIG. 13 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.
[0154] Referring to FIG. 13, a sensing service data flow (e.g., PDU 1) may be composed of an independent PDU session from a communication data flow (e.g., PDU 2), and the sensing service data flow may be separately mapped to a sensing-only sensing QoS flow (e.g., QoS flow 1). However, for example, the sensing QoS flow and the communication QoS flow may be mapped to the same DRB.
[0155] FIG. 14 illustrates rules for mapping QoS flows related to sensing service data to DRBs, according to one embodiment of the present disclosure. The embodiment of FIG. 14 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.
[0156] Referring to FIG. 14, a sensing service data flow (e.g., PDU 1) may be configured as an independent PDU session from a communication data flow (e.g., PDU 2), and the sensing service data flow may be mapped to the same QoS flow as the communication service data flow. Furthermore, for example, the sensing service data flow (e.g., PDU 1) and the communication data flow (e.g., PDU 2) may be mapped to the same DRB.
[0157] FIG. 15 illustrates rules for mapping QoS flows related to sensing service data to DRBs, according to one embodiment of the present disclosure. The embodiment of FIG. 15 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.
[0158] Referring to FIG. 15, the sensing service data flow may be composed of a PDU session independent of the communication data flow, and the sensing service data flow may be mapped to the same QoS flow as the communication service data flow. However, for example, the sensing data flow (e.g., PDU 1) may be mapped to a separate DRB from the communication data flow (e.g., PDU 2).
[0159] Proposal 3. Operations for managing SDAP functions and SDAP entities to support sensing services.
[0160] In this disclosure, we propose the following SDAP functions and operations for managing SDAP entities to support sensing services in ISAC.
[0161] For example, the SDAP sublayer can support the following functions:
[0162] - Transmit user plane data;
[0163] - Mapping between QoS flows and DRBs for both downlink and uplink;
[0164] - Mapping between MBS QoS flow flows and MRBs for downlink;
[0165] - Mapping between PC5 QoS flows and SL-DRB for NR sidelink communication;
[0166] - Mark QoS flow ID on both downlink and uplink packets;
[0167] - Marking PC5 QoS flow ID in unicast NR sidelink communication packets;
[0168] - Mapping between reflective QoS flows and DRBs for uplink SDAP data PDUs;
[0169] - Mapping between sensing QoS flows and sensing DRBs for ISAC.
[0170] For example, management of SDAP entities might be as follows:
[0171] For example, an SDAP entity may be located at an SDAP sublayer. For example, multiple SDAP entities may be defined for a UE. For example, there may be an SDAP entity configured for each PDU session or MBS session of an NR Uu. For example, for an NR sidelink, an SDAP entity may be configured for each destination layer-2 ID and cast type of the UE.
[0172] For example, an SDAP entity can receive / forward SDAP SDUs to / from upper layers, and can transmit / receive SDAP data PDUs to / from peer SDAP entities via lower layers.
[0173] For example, on the transmitting side, when an SDAP entity receives an SDAP SDU from a higher layer, it can construct a corresponding SDAP data PDU and transmit it to a lower layer.
[0174] For example, at the receiving end, when an SDAP entity receives an SDAP data PDU from a lower layer, it can retrieve the corresponding SDAP SDU and pass it on to the upper layer.
[0175] For example, if the DL SDAP header is set, mapping of reflective QoS flows and DRBs can be performed at the UE.
[0176] For example, the mapping of reflective QoS flows to MRBs may not be supported. In this case, for example, the MRB may not contain an SDAP header.
[0177] For example, for NR sidelink communication, mapping of reflective PC5 QoS flows to SL-DRB may not be supported.
[0178] For example, there may be an SDAP entity set up for an independent PDU session for an ISAC sensing service. For example, for ISAC sensing, an SDAP entity may be set up per sensing service ID of a sensing device, per sensing QoS flow ID, per sensing priority, per sensing service data flow ID, or per target sensing area (TSA).
[0179] FIG. 16 illustrates a mapping relationship between a QoS flow associated with a sensing service, a DRB for the sensing service, and a PDU session for the sensing service, according to an embodiment of the present disclosure. The embodiment of FIG. 16 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.
[0180] Referring to FIG. 16, the UE may be a sensing transmitter and / or a sensing receiver having sensing-related capabilities. The xNB may be a network node that performs a base station function that communicates with the UE via a wireless interface in a 6G wireless access network. Meanwhile, a 6G core network may be newly defined separately from the conventional Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), and Sensing Function (SF).
[0181] For example, when a 6G core network receives sensing service data from a data network that manages sensing data, the 6G core network can create a PDU session that only includes the sensing service data flow. Alternatively, for example, the 6G core network can define filtering rules for the sensing service data flow and map the sensing service data flow to a specific QoS flow.
[0182] For example, the 6G core network can configure / manage PDU sessions such that QoS flow #1 associated with sensing service #1, QoS flow #3 associated with sensing service #1, and QoS flow #2 associated with sensing service #1 are included in the PDU session for the sensing service. Alternatively, for example, the 6G core network can configure / manage PDU sessions such that QoS flow #1 associated with sensing service #1, QoS flow #3 associated with sensing service #1, and QoS flow #2 associated with sensing service #1 are not included in the PDU session for the communication service. Alternatively, for example, the 6G core network can configure / manage PDU sessions such that QoS flow #4 associated with communication service #1 is not included in the PDU session for the sensing service. For example, the PDU sessions for the sensing service and the PDU sessions for the communication service can be managed / configured independently of each other. Meanwhile, for example, information that can map each QoS flow and DRB can be transmitted from the 6G core network to the xNB.
[0183] For example, the xNB may create one or more DRBs based on information received from the 6G core network. For example, the xNB may map one or more QoS flows to the DRB. For example, the xNB may determine which QoS flows can be mapped to the DRB based on QoS requirements. For example, based on the fact that the QoS requirements of QoS flow #1 associated with sensing service #1 and QoS flow #2 associated with sensing service #2 are identical, the xNB may map QoS flow #1 associated with sensing service #1 and QoS flow #2 associated with sensing service #2 to DRB #1 for the sensing service. Alternatively, for example, based on the fact that the QoS requirements of QoS flow #1 associated with sensing service #1 are different from the QoS requirements of QoS flow #3 associated with sensing service #1, the xNB may map QoS flow #1 associated with sensing service #1 to DRB #1 for sensing service and may map QoS flow #3 associated with sensing service #1 to DRB #2 for sensing service. Meanwhile, for example, the xNB may not map DRB #1 for sensing service and DRB #2 for sensing service to QoS flow #4 associated with communication service #1. For example, DRB for sensing service and DRB for communication service may be managed / configured independently of each other.
[0184] Embodiments of the present disclosure can be extended and applied to all six sensing scenarios of FIG. 9 described above.

[0196] Referring to FIG. 17, in step S1710, the base station may receive sensing service data from a plane function for the sensing service. In step S1720, the base station may map a first quality of service (QoS) flow related to the sensing service data to a sensing data radio bearer.

[0201] For example, based on the plurality of QoS flows including the first QoS flow being related to the sensing service, the plurality of QoS flows may be mapped to the sensing data radio bearer.
[0202] Additionally, for example, the base station can receive configuration information for mapping between a QoS flow related to sensing and a data radio bearer related to sensing from a plane function for the sensing service. For example, based on the configuration information, the first QoS flow related to the sensing service data can be mapped to the sensing data radio bearer. For example, the configuration information can include at least one of a sensing QFI (QoS Flow ID) mapped per sensing service, a QoS requirement per sensing service, a sensing data radio bearer for the sensing service, a sensing QFI mapped per sensing data radio bearer, radio link control (RLC) configuration information for sensing service data, or packet data convergence protocol (PDCP) configuration information for sensing service data.

[0212] Referring to FIG. 18, in step S1810, the first device may receive an RRC (radio resource control) message including configuration information related to a data radio bearer from a base station. In step S1820, the first device may receive sensing service data from the base station. For example, a QoS flow related to the sensing service data may be mapped to a sensing data radio bearer. For example, the QoS flow related to the sensing service data may be included in a PDU (packet data unit) session for the sensing service.
[0213] 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 receive an RRC (radio resource control) message including configuration information related to a data radio bearer from a base station.

For example, the first 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 first device to: receive, from a base station, a radio resource control (RRC) message including configuration information related to a data radio bearer; and receive, from the base station, sensing service data. For example, a quality of service (QoS) flow related to the sensing service data may be mapped to a sensing data radio bearer. For example, the QoS flow related to the sensing service data may be included in a packet data unit (PDU) session for a sensing service.
[0215] According to one embodiment of the present disclosure, a processing device configured to control a first device may be provided.

For example, the QoS flow related to the sensing service data may be included in a packet data unit (PDU) session for a sensing service.
[0217] According to various embodiments of the present disclosure, a separate QoS model for sensing services can be defined in a 6G system. Specifically, for example, QoS flows related to sensing services (or DRBs related to sensing services, or PDU sessions related to sensing services) can be managed independently from QoS flows related to communication services (or DRBs related to communication services, or PDU sessions related to communication services). In this case, for example, resources on a DRB basis can be independently allocated and scheduled for each sensing service and each communication service, thereby preventing in advance the problem of large-capacity sensing traffic affecting the delay of communication traffic. Alternatively, for example, a scheduler at a base station can independently process DRBs for sensing services and DRBs for communication services according to separate priorities and QoS requirements, thereby improving scheduling efficiency. Alternatively, for example, by separately managing sensing services and communication services at the QoS flow and / or PDU session level, it is possible to stably process large-capacity transmission of sensing traffic while ensuring the quality of communication services.

[0235] FIG. 21 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 21 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.
[0236] Referring to FIG. 21, 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. 21 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 20. The hardware elements of FIG. 21 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 20. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 20. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 20, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 20.
[0237] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 21. Here, the codeword is an encoded bit sequence of an information block. The information block may include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal may be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).
[0238] 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.
[0239] 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.
[0240] 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. 21. For example, a wireless device (e.g., 100, 200 of FIG. 20) 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.
