[0060] FIG. 1 illustrates a communication procedure between devices 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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0061] Referring to FIG. 1, in step S101, the first device and the second device can perform synchronization. For example, the first device may be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device may 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 may perform an initial cell search operation. For example, the first device may detect at least one synchronization signal transmitted according to a rule predefined by the second device. Here, for example, the synchronization signal may include a plurality of synchronization signals (e.g., primary synchronization signal, secondary synchronization signal, etc.) classified according to structure or use. 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., cell identifier).

[0062] In step S103, the first device may obtain system information transmitted by the second device. For example, the system information may include information related to the attributes, characteristics, and / or capabilities of the second device that are necessary 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 the system information prior to receiving the system information. For example, the request and provision of the system information may be performed after a random access procedure described later.

[0063] In step S105, the first device and the second device may perform a random access procedure. For example, the first device may transmit and / or receive at least one message for the random access procedure (e.g., random access preamble, random access response message, etc.) based on information related to the 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 may transmit a preamble (e.g., Msg1) through the random access channel, and the first device may receive a random access response message (e.g., Msg2). The first device may transmit a message (e.g., Msg3) containing 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 may receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be transmitted and received as a single message (e.g., MsgA), and / or Msg2 and Msg4 can be transmitted and received as a single message (e.g., MsgB).

[0064] 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 controlling the connection (e.g., a radio resource control (RRC) layer), a layer handling mapping between a logical channel and a transmission channel (e.g., a media access control (MAC) layer), and a layer handling a physical channel (e.g., a physical (PHY) layer). For example, the first device and the second device may perform at least one of signaling to establish a connection, signaling to determine settings related to communication, and / or signaling to indicate allocated resources. For example, the control information may be signaled / transmitted through 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.

[0065] 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 data based on signaling of control information and transmit and / or receive it. 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, antenna-specific waveform demodulation, signal placement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0066] For example, the layers of the radio interface protocol between the first device and the second device can be classified into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, the physical layer belonging to layer 1 can provide an information transfer service using a physical channel, and the radio resource control (RRC) layer located at layer 3 can perform the role of controlling radio resources between the first device and the second device. For example, to this end, the RRC layer can exchange RRC messages between the first device and the second device.

[0067] FIG. 2 illustrates a radio protocol architecture according to one 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 said embodiment may be omitted. For example, FIG. 2(a) may represent a radio protocol stack in the user plane for uplink communication or downlink communication, and FIG. 2(b) may represent a radio protocol stack in the control plane for uplink communication or downlink communication. For example, FIG. 2(c) may represent a radio protocol stack in the user plane for device-to-device communication, and FIG. 2(d) may represent a radio protocol stack in the control plane for device-to-device communication.

[0068] For example, the physical layer can provide information transmission services to upper layers using a physical channel. For example, the physical layer can be connected to the upper layer, the MAC (medium access control) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through a transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted through a wireless interface. For example, data can be transmitted through a physical channel between different physical layers, for example, between the physical layers of a first device and a second device. For example, the physical channel can be modulated using the OFDM (orthogonal frequency division multiplexing) method, and time and frequency can be utilized as wireless resources.

[0069] For example, the MAC layer can provide services to the upper layer, the RLC (radio link control) layer, through logical channels. For example, the MAC layer can provide mapping functions from multiple logical channels to multiple transmission channels. For example, the MAC layer can provide logical channel multiplexing functions through mapping from multiple logical channels to a single transmission channel. For example, the MAC sublayer can provide data transmission services over logical channels.

[0070] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee various quality of service (QoS) required by a radio bearer (RB), the RLC layer can provide three modes of operation: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat requests (ARQ).

[0071] For example, the RRC (radio resource control) layer may be defined only in the control plane. For example, the RRC layer may be responsible for controlling logical channels, transmission channels, and physical channels in relation to the configuration, reconfiguration, and release of radio bearers. For example, RB may refer to a logical path provided by the first layer (e.g., physical layer) and the second layer (e.g., MAC layer, RLC layer, PDCP (packet data convergence protocol) layer, SDAP (service data adaptation protocol) layer, etc.) for data transfer between a first device and a second device.

[0072] For example, the functions of the PDCP layer in the user plane may include the delivery of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include the delivery of control plane data and encryption / integrity protection.

[0073] For example, the establishment of an RB can mean the process of defining the characteristics of the wireless protocol layer and channel to provide specific services, and setting each specific parameter and method of operation. For example, an RB can be divided into two types: an SRB (signaling radio bearer) and a DRB (data radio bearer). For example, an SRB can be used as a channel to transmit RRC messages in the control plane, and a DRB can be used as a channel to transmit user data in the user plane.

[0074] For example, if an RRC connection is established between the RRC layer of the terminal and the RRC layer of the base station, the terminal is in the RRC_CONNECTED state, and if not, it may be in the RRC_IDLE state. For example, in the case of NR, an additional RRC_INACTIVE state is defined, and a terminal in the RRC_INACTIVE state maintains a connection with the core network while releasing the connection with the base station.

[0075] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) that transmits system information and / or a shared channel (SCH) that transmits user traffic or control messages. For example, traffic or control messages for a downlink multicast or broadcast service may be transmitted via a downlink SCH or via a separate multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) that transmits initial control messages and / or a shared channel (SCH) that transmits user traffic or control messages. For example, a logical channel located above the 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).

[0076] FIG. 3 shows the structure of a wireless frame according to one 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.

[0077] Referring to FIG. 3, radio frames may be used, for example, 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 contain 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 by subcarrier spacing (SCS). For example, each slot may contain 12 or 14 OFDM(A) symbols according to a cyclic prefix (CP).

[0078] For example, when normal CP is used, each slot may contain 14 symbols. For example, when extended CP is used, each slot may contain 12 symbols. Here, for example, the symbols may include OFDM symbols (or CP-OFDM symbols) and SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0079] Table 2 below shows the number of symbols per slot (N) according to 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 ) exemplifies.

[0080] CP Type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slotNormal CP 15kHz (u=0) 1410 130kHz (u=1) 1420 260kHz (u=2) 1440 4120kHz (u=3) 1480 8240kHz (u=4) 14160 16 Extended CP 60kHz (u=2) 1240 4

[0081] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be configured differently among multiple cells merged into a single terminal. Accordingly, the (absolute time) interval of a time resource (e.g., subframe, slot, or TTI (transmit time interval)) composed of the same number of symbols may be configured differently among the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTI, etc. may be referred to as time units.

[0082] For example, multiple numerologies or SCSs may be supported to support various services. For example, if the SCS is 15 kHz, a wide area in traditional cellular bands may be supported, and if the SCS is 30 kHz / 60 kHz, dense-urban, lower latency, and wider carrier bandwidth may be supported. For example, if the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz may be supported to overcome phase noise.

[0083] FIG. 4 shows a slot structure of a frame according to one 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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0084] 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 a single numerology (e.g., SCS, CP length, etc.). For example, a carrier may include up to N BWPs (where N is a positive integer). For example, data communication may be performed through an active BWP. For example, each element may be referred to as a resource element (RE) in a resource grid and may be mapped to a single complex symbol.

[0085] For example, a BWP can be a continuous set of PRBs in a given numerology. For example, a PRB can be selected from a continuous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0086] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the terminal may not monitor downlink radio link quality on DL BWPs other than the active DL BWP on the PCell (primary cell). For example, the terminal may not receive PDCCH (physical downlink control channel), PDSCH (physical downlink shared channel), or CSI-RS (channel state information-reference signal) (except for RRM (radio resource management)) outside of the active DL BWP. For example, the terminal may not trigger CSI (channel state information) reporting for an inactive DL BWP. For example, the terminal may not transmit PUCCH (physical uplink control channel) or PUSCH (physical uplink shared channel) outside of the active UL (uplink) BWP. For example, for the downlink, the initial BWP can be given as a consecutive set of resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For example, for the uplink, 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 the upper layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if the terminal fails to detect DCI (downlink control information) for a certain period, the terminal can switch the active BWP of the terminal to the default BWP.

[0087] 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.

[0088] Referring to FIG. 5, for example, a common resource block (CRB) may be a numbered carrier resource block from one end of the 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 the resource block grid.

[0089] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP It can be set by ). For example, point A may be an external reference point of the PRB of a carrier where the subcarrier 0 of all numerologies (e.g., all numerologies supported by the network in that carrier) are aligned. For example, offset may be the PRB interval between the lowest subcarrier in a given numerology and point A. For example, bandwidth may be the number of PRBs in a given numerology.

[0090] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to one 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 said embodiments may be omitted.

[0091] As core implementation technologies for 6G systems, technologies such as artificial intelligence (AI), THz (Terahertz) communication, optical wireless technology, free space optical transmission (FSO) backhaul networks, large-scale 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.

[0092] FIG. 7 illustrates an example of a flexible network topology 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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0093] For example, to compensate for incomplete areas of network coverage, a network topology in which the Split Radio Access Network (RAN) is configured more flexibly and resiliently may be considered. For example, to this end, various nodes such as IAB nodes, relays, and RF repeaters, as exemplified in Fig. 7, may be applied, and NTN may be integrated. For example, an IAB node may correspond to a node that provides wireless backhaul. For example, a relay may refer to any intermediate point, and in the case of a sidelink relay where a terminal functions as a relay, it may collectively refer to a terminal-to-network (U2N) relay and a terminal-to-terminal (U2U) relay. For example, an RF repeater may correspond to a node that performs simple signal amplification and forwarding functions, and in the case of a network-controlled repeater, it may adjust transmit / receive settings based on information provided by the network as well as signal amplification and forwarding. For example, an NTN node may correspond to a satellite or aircraft that provides NTN coverage that is difficult for a terrestrial network to provide. For example, in addition to these examples, various intermediate points can be introduced to improve network topology.

[0094] Referring to FIG. 7, for example, a split RAN can support the division of a base station into one centralized unit (CU) and one or more distributed units (DU). For example, the CU and DU may correspond to logical units. For example, the CU may be further divided into a control plane (CP) portion and one or more user plane (UP) portions. For example, since a failure in the CU-CP affects the DU as well as the CU-UP, various intermediate points may be introduced to compensate for this.

[0095] For example, an intermediate point may correspond to a terminal or a base station depending on its relative relationship with other nodes. For example, an IAB node may include a mobile-termination (MT) portion and a DU. For example, the MT may connect the IAB node to a donor node. For example, the DU of an IAB node may serve other terminals or connect to other IAB nodes to provide multi-hop wireless backhaul to terminals. For example, an IAB node may correspond to a base station in its relative relationship with a user-side node and to a terminal in its relative relationship with a network-side node.

[0096] For example, in some examples of the present disclosure, the description of a terminal may apply equally to an intermediate point corresponding to a terminal in relation to a network-side endpoint as well as to a user-side endpoint. For example, similarly, in some examples of the present disclosure, the description of a base station may apply equally to an intermediate point corresponding to a base station in relation to a user-side endpoint as well as to a network-side endpoint. For example, however, in most cases where there is no additional description of the operation of three or more entities, the communication entities in the present disclosure are briefly described by the term terminal and / or base station (or first node and / or second node), wherein the term terminal and / or base station (or first node and / or second node) may be interpreted to include or replace any endpoint or any intermediate point in relation to other nodes.

[0097] For example, in some examples of the present disclosure, for the sake of brevity of description, the subject of the operation may be referred to as a base station and / or a terminal (or a first node and / or a second node). Additionally, for example, the term base station and / or terminal (or a first node and / or a second node) may be interpreted or substituted as in the following examples: for example, the base station (or the first node) and the terminal (or the second node) may correspond to a first endpoint and a second endpoint, respectively; may correspond to an endpoint and an intermediate point, respectively; may correspond to an intermediate point and an endpoint, respectively; or may correspond to a first intermediate point and a second intermediate point, respectively.

[0098] For example, in the present disclosure, there may be no intermediate points between a base station and a terminal, or there may be one or more. If intermediate points exist, the intermediate points may correspond to IAB nodes, relays, RF repeaters, NTN (non-terrestrial network) nodes, or nodes supporting other functions. The intermediate points may be nodes with a fixed location or nodes with an indefinite location.

[0099] FIG. 8 illustrates an example of a communication scenario based on a 6G system 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 said embodiment may be omitted.

[0100] Referring to FIG. 8, NTN communication can be performed based on a satellite network, HIBS (high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS)), and an aeronautical communication-capable terminal (e.g., AAM). For example, to improve coverage, devices such as a satellite network, HIBS, and an aeronautical communication-capable terminal (e.g., AAM) 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.

[0101] FIG. 9 illustrates a non-terrestrial network scenario according to one embodiment of the present disclosure. FIG. 10 illustrates a non-terrestrial network scenario according to one embodiment of the present disclosure. The embodiments of FIG. 9 and 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.

[0102] FIG. 9 illustrates a non-terrestrial network scenario based on a transparent payload, and FIG. 10 illustrates a non-terrestrial network scenario based on a regenerative payload. For example, a non-terrestrial network may generally include the following elements.

[0103] - One or more satellite gateways connecting non-terrestrial networks to public data networks

[0104] - Feeder link or wireless link between the satellite gateway and the satellite (or UAS platform)

[0105] - Service link or wireless link between user equipment and satellite (or UAS platform)

[0106] - A satellite (or UAS platform) capable of implementing transparent or regenerated (including onboard processing) payloads. For example, the satellite (or UAS platform) can generate multiple beams across a given service area, typically defined by a line of sight. For example, the beam footprint may typically be elliptical. For example, the line of sight of the satellite (or UAS platform) may vary depending on the onboard antenna diagram and the minimum elevation angle. For example, for a transparent payload, radio frequency filtering, frequency conversion, and amplification may be performed. Thus, the repeating waveform signal in the payload may not be altered. For example, for a regenerated payload, radio frequency filtering, frequency conversion, and amplification, as well as demodulation / decoding, switching and / or routing, and coding / modulation may be performed. This can effectively be equivalent to equipping the satellite (or UAS platform) with all base station functions.

[0107] - Optionally, Inter-satellite Link (ISL)

[0108] - User equipment can be serviced by a satellite (or UAS platform) within the target service area.

[0109] FIG. 11 illustrates examples of an NTN access network according to one embodiment of the present disclosure. FIG. 11 (a) illustrates an example of a transparent payload according to one embodiment of the present disclosure. FIG. 11 (b) illustrates an example of a regenerated payload according to one embodiment of the present disclosure. An 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 said embodiment may be omitted.

[0110] Referring to FIG. 11(a), for example, the satellite / HAPS can perform only the role of a simple repeater, receive uplink signals from the UE and transmit them to the Gateway, and relay downlink signals generated at the Gateway back to the UE. Here, for example, communication between the UE and the satellite can use NR radio frequency f1, and communication between the satellite and the Gateway can use NR radio frequency f2. For example, the actual 5G radio access network (e.g., 5G RAN) function is deployed at the Gateway or ground base station (e.g., gNB) located on the ground and can be coupled with the 5G core network (e.g., 5G CN). Therefore, for example, the satellite can operate as a simple transponder structure that transparently transmits signals at the physical layer level without performing separate signal processing functions. For example, the transparent payload of FIG. 11(a) may be related to the transparent payload of FIG. 9. For example, the transparent payload of Fig. 11 (a) may be related to the NTN architecture discussed in 3GPP Rel-17 and Rel-18.

[0111] Referring to FIG. 11(b), for example, the satellite / HAPS itself may be equipped with 5G RAN functions and may possess payload processing capabilities that include base station functions, rather than being a simple repeater. For example, communication between the UE and the satellite may use NR radio frequency f1, and communication between the satellite and the gateway may use NR radio frequency f2. Here, for example, the gateway is connected to a 5G core network (e.g., 5G CN), and since the satellite can directly provide RAN functions to the UE, it can replace or supplement a ground base station (e.g., gNB). For example, since the satellite has a structure that transmits NR signals after receiving, demodulating, and processing them, rather than simply relaying them, more intelligent wireless resource control and quality of service management are possible. For example, the regeneration payload in FIG. 11(b) may be related to the regeneration payload in FIG. 10. For example, the replay payload of Fig. 11 (b) may be related to the NTN architecture that can be discussed in 3GPP Rel-19 and thereafter.

[0112] For example, an NTN may be disclosed that features an access network servicing UEs based on a ground-based gNB (satellite hub or gateway level) and a satellite / aerial carrying a bent pipe payload. In FIG. 11, for example, the satellite or aerial may relay “satellite-friendly” NR signals between the gNB and the UEs in a transparent manner. For example, the UE may communicate with the satellite via a radio interface (e.g., Uu), and the satellite may transmit the signal to a ground base station (e.g., gNB). For example, the gNB may perform the role of a 5G radio access network (e.g., RAN) and may be connected to a 5G / 6G core (e.g., 5GC / 6GC) via an NG interface (e.g., NGc, NGu). For example, the 5GC / 6GC may be connected to an external data network via an N6 interface. Therefore, for example, in this structure, a satellite can extend the wireless section to mediate the connection between the UE and the ground base station, and subsequent procedures can operate in the same way as the existing 5G structure. For example, this NTN architecture can be associated with the transparent payload of FIG. 11 (a).

[0113] For example, an NTN may be disclosed that features an access network servicing UEs based on a satellite / aerial equipped with a gNB. In FIG. 12, for example, the satellite or aerial may include all or part of a gNB for generating / receiving “satellite-friendly” NR signals for transmitting and receiving with UEs. For example, this may require sufficient on-board processing power to deploy gNB or relay node functions. For example, a UE may communicate with the satellite via a radio interface (e.g., Uu), and the satellite may transmit signals to a ground base station (e.g., gNB). For example, the gNB may perform the role of a 5G radio access network (e.g., RAN) and may be connected to a 5G / 6G core (e.g., 5GC / 6GC) via an NG interface (e.g., NGc, NGu). For example, 5GC / 6GC can be connected to an external data network through the N6 interface. Thus, for example, in this structure, a satellite can extend the wireless section to mediate the connection between the UE and the ground base station, and subsequent procedures can operate in the same way as the existing 5G structure. For example, this NTN architecture can be related to the replay payload of FIG. 11 (b).

[0114] FIG. 12 illustrates an example of signaling between a base station and a terminal according to an embodiment of the present disclosure. FIG. 12(a) illustrates an example of uplink data transmission and reception according to an embodiment of the present disclosure. FIG. 12(b) illustrates an example of downlink data transmission and reception according to an 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.

[0115] For example, FIG. 12 may illustrate an example of signaling between a base station and a terminal performing NR FR1, FR2, or FR2-2 transmission and reception of one or more physical channels / signals to which the method proposed in the present disclosure may be applied. FIG. 12 is for convenience of explanation only and is not intended to limit the scope of the present disclosure.

[0116] Referring to FIG. 12(a), for example, a base station can schedule uplink transmissions such as frequency / time resources, transport layer, uplink precoder, MCS, etc. For example, the base station can determine a beam for the terminal's PUSCH transmission through the operations described above. For example, the terminal can receive a DCI on the PDCCH from the base station for uplink scheduling (e.g., including scheduling information for PUSCH). For example, the terminal can transmit uplink data to the base station on the PUSCH.

[0117] Referring to FIG. 12(b), for example, a base station can schedule downlink transmissions such as frequency / time resources, a transport layer, a downlink precoder, an MCS, etc. For example, the base station can determine a beam for the terminal's PDSCH transmission through the operations described above. For example, the terminal can receive downlink control information (DCI) for downlink scheduling (e.g., including scheduling information for the PDSCH) from the base station on the PDSCH. For example, the terminal can receive downlink data from the base station on the PDSCH. For example, the terminal can transmit HARQ-ACK feedback to the base station.

[0118] FIG. 13 illustrates an example of NTN 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.

[0119] Referring to Fig. 13, examples according to NTN platform types can be shown. For example, examples according to NTN platform types may be HAPS (High-Altitude Platform Station), LEO (Low Earth orbit), MEO (Medium Earth orbit), or GEO (Geo-stationary Earth orbit).

[0120] For example, parameters related to the HAPS (High-Altitude Platform Station) may be as follows. For example, the altitude of the HAPS (High-Altitude Platform Station) may be 20 km. For example, the beam footprint size of the HAPS (High-Altitude Platform Station) may be 5-200 km.

[0121] For example, parameters related to LEO (Low Earth orbit) may be as follows. For example, the altitude of LEO (Low Earth orbit) may be 300–1500 km. For example, the beam footprint size of LEO (Low Earth orbit) may be 100–1000 km. For example, the satellite velocity of LEO (Low Earth orbit) may be 7.56 km / sec (for LEO-600). For example, the maximum propagation delay of LEO (Low Earth orbit) may be 25.77 msec (for LEO-600).

[0122] For example, parameters related to MEO (Medium Earth orbit) may be as follows. For example, the altitude of MEO (Medium Earth orbit) may be 7,000–25,000 km. For example, the beam footprint size of MEO (Medium Earth orbit) may be 100–1,500 km. For example, the maximum propagation delay of MEO (Medium Earth orbit) may be 95.19 msec (for MEO-10000).

[0123] For example, parameters related to the GEO (Geo-stationary Earth orbit) may be as follows. For example, the altitude of the GEO (Geo-stationary Earth orbit) may be 35,786 km. For example, the beam footprint size of the GEO (Geo-stationary Earth orbit) may be 200-3,500 km. For example, the satellite velocity of the GEO (Geo-stationary Earth orbit) may be 3.1 km / sec (negligible). For example, the maximum propagation delay of the GEO (Geo-stationary Earth orbit) may be 541.46 msec.

[0124] For example, to effectively operate an NTN with a very long RTT, the scheduling offset is class This can be introduced.

[0125] FIG. 14 is K according to one embodiment of the present disclosure. offset and K macExamples of are shown. The embodiment of FIG. 14 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0126] Referring to Fig. 14, for example, class Examples of can be presented. For example, service link RTT can be the RTT between the terminal and the satellite. For example, feeder link RTT can be the RTT between the satellite and the base station. For example, common TA can be the TA between the satellite and the RP. For example, can be an offset value representing the RTT of the uplink time synchronization reference point (RP). For example, can mean the sum of the service link RTT and the common TA (if indicated). For example, may be an offset value representing the RTT between the RP and the gNB. For example, the feeder link RTT is the common TA (if indicated) and It can mean the sum of.

[0127] FIG. 15 illustrates examples of UE-specific TA and common TA 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, suggestions, methods, and / or operations of said embodiment may be omitted.

[0128] Referring to FIG. 15, a terminal-specific TA can be acquired to compensate for transmission delays on the service link, and a common TA can be acquired to compensate for transmission delays between the RP (reference point) and the satellite.

[0129] For example, in an NTN-based communication system, a terminal can calculate a TA based on the terminal's GNSS (global navigation satellite system) capabilities (e.g., terminal location) and orbit-related upper-layer parameters transmitted from the base station, and this is a terminal-specific TA ( It can be referred to as ). For example, if orbit-related upper-layer parameters are not received from the base station, the terminal-specific TA may be set to 0. For example, common TA parameters, which are upper-layer parameters transmitted from the base station (e.g., , , and / or TA obtained based on ) common TA( It can be referred to as ). For example, if common TA parameters are not transmitted from the base station, the common TA can be set to 0. Accordingly, for example, in an NTN-based communication system, the total TA value (TTA) is “ It can be obtained as ”. For example, can refer to the TA offset value provided to the terminal per serving cell, and can mean a value obtained based on the timing advance command.

[0130] Referring to FIG. 15, for example, in Rel-17 NTN, the terminal can calculate the TA itself based on the terminal's GNSS capability and base station guidance information (e.g., ephemeris information), which can be designated as a terminal-specific (UE-specific) TA. For example, a TA calculated based on common TA parameters indicated by the base station can be designated as a common TA, and the final TA based thereon can be based on FIG. 16 and the description related to FIG. 16.

[0131] FIG. 16 illustrates an example of an uplink-downlink timing relationship according to one 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, suggestions, methods, and / or operations of the embodiments may be omitted.

[0132] Referring to FIG. 16, the uplink frame number i for the transmission from the UE is before the start of the corresponding downlink frame from the UE You can start here

[0133] - and ...can be given in Section 4.2 of TS 38.213, and This may be excluded for msgA transmissions on PUSCH that are to be used;

[0134] - It can be derived from the upper-level parameters ta-Common, ta-CommonDrift, and ta-CommonDriftVariant if indicated, and otherwise It could be;

[0135] - is calculated by the UE based on UE position and serving-satellite-orbit-related upper-layer parameters if indicated, and otherwise It could be.

[0136] For example, there may be TA misalignment.

[0137] For example, in NR NTN, a TA mismatch may occur if the gNB does not receive a TA report, if the existing TA report is outdated, or if the granularity of the TA report is insufficient. For example, if the UE does not perform any TA reporting, the gNB [uses] several key scheduling variables (e.g., , Since ) cannot be configured, the above scenario (e.g., no TA reporting) may not be considered a feasible scenario. Therefore, assuming that the UE performs TA reporting, the magnitude of TA mismatch caused by TA reporting obsolescence and / or TA reporting granularity may need to be addressed. For example, if the UE performs TA reporting on NR NTN, TA discrepancies may occur primarily due to outdated TA reporting and / or coarse TA reporting granularity. For example, to support HD-FDD (e)RedCap UE, issues regarding quantitative-level TA misalignment between the gNB and the UE may need to be addressed.

[0138] Meanwhile, differences resulting from outdated TA reporting may occur when the UE location changes, and may occur proportionally to RTT differences depending on the UE location within the cell (e.g., the difference between the minimum TA and the maximum TA).

[0139] FIG. 17 illustrates an example of TA mismatch within a beam / cell according to one embodiment of the present disclosure. The embodiment of FIG. 17 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0140] Referring to Fig. 17, for example, assuming an LEO of 600 km, a beam size of 50 km, and a target elevation angle of 30 degrees, the difference between the shortest RTT (minimum TA) and the longest RTT (maximum TA) can be within about 300 µs, which corresponds to about 4 to 5 OFDM symbols using a 15 kHz SCS.

[0141] For example, assuming an LEO of 600 km, a beam size of 50 km, and a target elevation angle of 30 degrees, the difference between the shortest RTT (minimum TA) and the longest RTT (maximum TA) is within approximately 300 µs, which corresponds to about 4 to 5 OFDM symbols with a 15 kHz SCS. For example, considering that the TA reported granularity of NTN is 1 ms (e.g., 14 OFDM symbols using a 15 kHz SCS), in the LEO example, the main cause of the TA discrepancy may be the TA reported granularity rather than the old TA reported. For example, for an LEO of 600 km, a beam size of 50 km, and a target elevation angle of 30 degrees, the difference between the minimum TA and the maximum TA may be smaller than the TA reported granularity (e.g., 1 ms). For example, in the case of HD-FDD (e)RedCap UE support, issues regarding the enhanced TA reporting mechanism, particularly TA reporting granularity, may need to be addressed.

[0142] For example, there may be a DL / UL collision under TA misalignment.

[0143] When comparing the timing advances of NTN and TN due to satellite movement, the timing advance of the service link between the satellite and the UE can be estimated by the UE itself. For example, the gNB can obtain the TA value through TA reporting, but due to the current 1ms granularity reported by the TA, the gNB cannot obtain the exact TA used by the UE, and the UE side cannot know when or which transmission will collide. For example, since the rule for when a DL reception collides with a UL transmission is intended to avoid collisions through gNB scheduling, the NTN gNB may experience difficulties in determining whether the UE is in an uplink slot or a downlink slot.

[0144] For example, the terminal may receive satellite orbit information via system information and / or RRC signaling. For example, satellite orbit information may be implemented / supported in a position and velocity state vector orbit format, and / or an orbital parameter orbit format. For example, the position and velocity state vector orbit format may consist of less than 17 bytes (e.g., 132 bits). For example, the field size for position (x, y, z)(m) may be 78 bits, and velocity (v x , v y , v z The field size for )(m / s) can be 54 bits. For example, the orbital parameter orbital format can be composed of less than 21 bytes (e.g., 164 bits).

[0145] FIG. 18 illustrates an example of an orbital parameter orbital format according to one embodiment of the present disclosure. The embodiment of FIG. 18 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of said embodiments may be omitted.

[0146] Referring to FIG. 18, information related to the orbital parameter orbit format (e.g., ephemeral information) includes the semi-major axis "α" (e.g., 33 bits) [m], the eccentricity "e" (in an elliptical satellite orbit, 0 <e<1) (예를 들어, 20 비트), 근점 편각(argument of periapsis) "ω"(예를 들어, 28 비트) [rad], 승교점 경도(longitude of ascending node) "Ω" (예를 들어, 28 비트) [rad], (궤도) 경사(inclination) "i" (예를 들어, 27 비트) [rad], 및 / 또는 평균 근점 이각(mean anomaly) "M0" = 에포크 t0[JD]에서 M(t0) (예를 들어, 28 비트) [rad] 중 적어도 어느 하나를 포함할 수 있다.

[0147] Conventionally, NR positioning up to Release 17 only supported network-based Uu positioning, which performed location search based on a connection between the target UE and the network (gNB / LMF). Meanwhile, starting with NR Release 18, sidelink positioning (SL positioning) using sidelink communication can be supported. Sidelink positioning is a new method that allows positioning operations to be performed by exchanging positioning reference signals through direct connections with anchor UEs surrounding the target UE, rather than with base stations. Positioning operations at the physical layer can be performed by determining the location through the transmission and measurement of the SL PRS (sidelink positioning reference signal) between the target UE and the anchor UE.

[0148] Uu positioning may use the LPP protocol. An LPP session can be a point-to-point communication protocol between a target UE and an LMF. Through the LPP protocol, the target UE can receive information necessary for positioning from the LMF. The LMF can establish the target UE and the base station (gNB) respectively, exchange positioning-related messages, and perform positioning operations through the LPP protocol and the NRPPa protocol. Meanwhile, in Release 18's sidelink positioning, positioning operations can be performed by exchanging sidelink positioning protocol messages with the target UE, server UE (or LMF), and anchor UE. In sidelink positioning, the sidelink positioning protocol (SLPP) can be used for establishing and exchanging messages between UEs.

[0149] Positioning methods (e.g., sidelink positioning) have the disadvantage that the target must possess a communication terminal and that signaling messages for location measurement must be exchanged between the transmitter and the target. This leads to increased overhead for signal processing between the target and the transmitter, and presents a fundamental limitation in that positioning itself is impossible if the target does not possess a separate communication terminal.

[0150] In contrast, the Integrated Sensing and Communication (ISAC) method can accurately detect the presence and movement of a target regardless of whether the target is carrying a communication terminal, and furthermore, can reliably acquire detailed sensing information such as the target's distance, speed, and angle. The ISAC method can estimate the characteristics of a target simply by analyzing the information reflected from the target after the signal radiated by the transmitter, without requiring a separate response signal or message from the target. Accordingly, ISAC has the advantage of significantly reducing the amount of signaling compared to positioning methods, thereby drastically lowering overhead, and simultaneously supporting more efficient and flexible sensing and communication operations.

[0151] Examples of various application fields where ISAC can be applied are illustrated. Specifically, ISAC can support predictive maintenance and employee localization and authorization in the fields of smart manufacturing and industrial IoT, and can provide weather prediction, pollution monitoring, rain monitoring, and insect monitoring in the field of environmental monitoring.

[0152] In addition, in the field of Sensing as a Service, it can be utilized for drone monitoring and management, mobile crowd sensing, channel knowledge map construction, and cooperative localization and imaging.

[0153] Furthermore, in the field of remote sensing, it can support satellite imaging and broadcasting and drone swarm SAR imaging, and in the field of smart home, it can be utilized for human proximity detection, spatial-aware control, sensing-aided wireless charging, fall detection, vital signal monitoring, etc.

[0154] In addition, in the field of human-computer interaction (HCI), it enables gesture recognition, keystroke recognition, and arm / head activity recognition, and in the field of vehicle-to-everything communication (V2X), it enables the provision of various services such as high precision location, vehicle platooning, extended sensor, simultaneous localization and mapping, and secure hand-free access.

[0155] Recently, Integrated Sensing and Communication (ISAC) technology, which integrates target sensing and user communication functions in 6th generation (6G) mobile communication systems, is attracting attention as a key standardization target. Based on advantages such as efficient frequency usage, reuse of existing communication infrastructure, and cost savings resulting from integrated sensing and communication sensors, ISAC technology is emerging as an essential technology in various industries, including autonomous driving, smart factories, unmanned aerial vehicles, and healthcare.

[0156] For example, a support scenario for sensing services in an ISAC could be as follows. Here, for example, the network could be a gNB.

[0157] FIG. 19 illustrates an example of six sensing scenarios for a sensing service according to an embodiment of the present disclosure. Specifically, FIG. 19 (a) illustrates an example of gNB monostatic, FIG. 19 (b) illustrates an example of gNB bistatic, and FIG. 19 (c) illustrates an example of gNB-UE bistatic. Additionally, FIG. 19 (d) illustrates an example of UE-gNB bistatic, FIG. 19 (e) illustrates an example of UE monostatic, and FIG. 19 (f) illustrates an example of UE bistatic. The embodiment of FIG. 19 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0158] Referring to Fig. 19, for example, six sensing scenarios for a sensing service in an ISAC may be as follows.

[0159] For example, six principal sensing modes:

[0160] - gNB monostatic (the same gNB performs both the transmitter (Tx) and receiver (Rx)

[0161] - gNB bi-static (one gNB is the transmitter (Tx) and the other gNB is the receiver (Rx)

[0162] - gNB-to-UE bi-static (gNB is the transmitter (Tx) and UE is the receiver (Rx)

[0163] - UE-to-gNB bi-static (UE is the transmitter (Tx) and gNB is the receiver (Rx)

[0164] - UE Monostatic (The same UE performs both the transmitter (Tx) and receiver (Rx)

[0165] - UE bi-static (One UE is the transmitter (Tx) and the other UE is the receiver (Rx)

[0166] The introduction of AI into communications can streamline and enhance real-time data transmission. AI can determine how complex target tasks are performed using numerous analyses. For example, AI can increase efficiency and reduce processing latency. Time-consuming tasks such as handover, network selection, and resource scheduling can be performed instantly by using AI. AI can also play a significant role in M2M, machine-to-human, and human-to-machine communication. Furthermore, AI can enable rapid communication in brain-computer interfaces (BCI). 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.

[0167] In the following, a functional framework for AI / ML operations can be described.

[0168] For example, to provide a more specific explanation of AI (or AI / ML) below, terms can be defined as follows.

[0169] - Data collection: Data collected from network nodes, management entities, or terminals, serving as a basis for AI model training, data analysis, and inference.

[0170] - AI model: A data-driven algorithm that applies AI technology to generate a set of outputs containing predictive information and / or decision parameters based on a set of inputs.

[0171] - AI / ML Training: An online or offline process of training an AI model by learning features and patterns that best represent data and acquire an AI / ML model trained for inference.

[0172] - AI / ML Inference: A process of making predictions or deriving decisions based on collected data and AI models using trained AI models.

[0173] For example, life cycle management (LCM) procedures for AI / ML models (e.g., model training, model deployment, model inference, model monitoring, model updating, etc.) can be classified into functionality-based LCM and model-based LCM. For instance, in functionality-based LCM, an AI / ML model may not be identified by the network, and the network can direct the activation, deactivation, fallback, or switching of AI / ML functionality. For instance, in model-ID (identifier)-based LCM, an AI / ML model can be identified by the network, and the network / terminal can activate, deactivate, select, or switch the AI / ML model via the model ID.

[0174] FIG. 20 is a diagram illustrating an overall functional framework for an AI / ML model according to one embodiment of the present disclosure. The embodiment of FIG. 20 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of said embodiment may be omitted. For example, not all functions and / or all data / information / command signals illustrated in FIG. 20 may be performed within a specific node, and only some may be performed. For example, FIG. 20 may illustrate a general functional architecture related to both functionality-based LCM and model-based LCM. For example, some functions or some data / information / command flows (e.g., arrows) illustrated in FIG. 20 may be omitted.

[0175] Referring to FIG. 20, for example, a general functional framework may be configured to include a data collection function (10), a model training function (20), a management function (30), an inference function (40), and a model storage function (50).

[0176] For example, the data collection function (10) may be a function that provides input data to the model training function (20), management function (30), and inference function (40). For example, the data collection function (10) may perform data preparation based on raw data and provide input data processed through data preparation. For example, examples of raw data may include received data / measurement data from terminals or other network entities, inference / output of AI / ML models, etc. For example, the data collection function (10) may be performed by a single entity (e.g., terminal, network node, etc.) but may also be performed by multiple entities.

[0177] Here, for example, training data (11) may refer to data required as input for an AI / ML model training function (20). For example, monitoring data (12) may refer to data required as input for a management function (30) of an AI / ML model or AI / ML function. For example, inference data (13) may refer to data required as input for an AI / ML inference function (40).

[0178] For example, the model training function (20) may be a function that performs AI / ML model training, validation, and testing, which can generate model performance metrics that can be used as part of an AI / ML model testing procedure. For example, the model training function (20) may perform data preparation (e.g., data pre-processing and cleaning, forming and transformation) based on training data (11) transferred from the data collection function (10) if necessary.

[0179] For example, if there is a trained / updated model (21): model storage function (50), it can be used to transfer the trained, validated, and tested AI / ML model to the model storage function (50) or to transfer an updated version of the model to the model storage function (50).

[0180] For example, the management function (30) may be a function that supervises the operation of an AI / ML model or an AI / ML function. Additionally, for example, the management function (30) may make decisions to ensure appropriate inference operations based on data received from the data collection function (10) (e.g., monitoring data (12)) and / or data received from the inference function (40) (e.g., inference output (41)).

[0181] For example, a management instruction (32) may be information required as input to manage an inference function (40). For example, the relevant information may include the selection / (de)activation / switching of an AI / ML model or an AI / ML-based function, and may also include, for example, a fallback to a non-AI / ML operation (e.g., not relying on the inference process).

[0182] For example, a model transfer / delivery request (33) can be used to request model(s) from a model storage function (50).

[0183] For example, a performance feedback / retraining request (31) may refer to information required as input to a model training function (20) (e.g., for the purpose of retraining or updating a model).

[0184] For example, the inference function (40) may be a function that provides an output from the process of applying an AI / ML model or an AI / ML function using data (e.g., inference data (13)) provided by the data collection function (10) as input. For example, data preparation (e.g., data preprocessing and cleaning, formatting and transformation) may be performed based on the inference data (13) delivered by the data collection function (10). For example, if necessary, the inference function (40) may perform data preparation (e.g., data pre-processing and cleaning, forming and transformation) based on the inference data (13) provided by the data collection function (10).

[0185] For example, the inference output (41) may be data used in the management function (30) to monitor the performance of an AI / ML model or an AI / ML function. For example, the inference output (41) may include the inference output of an AI / ML model generated by the inference function (40), and the details of the inference output may vary depending on the use case.

[0186] For example, the model storage function (50) may be a function that stores a trained / updated model that can be used to perform an inference function (40). For example, the model storage function (50) exemplified in FIG. 20 may be used as a reference point (if any) applicable to protocol termination, model transmission / delivery, and related processes. Additionally, for example, the model storage function (50) is an example and is not intended to restrict the storage location of the actual AI / ML model and may be omitted.

[0187] For example, model transfer / delivery (51) can be used to transfer an AI / ML model to an inference function.

[0188] For example, a one-side model may refer to an AI / ML model in which inference is performed entirely by a single node (e.g., a terminal or a network). Here, for example, the training of the AI / ML model may also be performed entirely by a single node. For example, the training and inference of the AI / ML model may be performed by the same node, or they may be performed by different nodes.

[0189] For example, a two-side model may refer to an AI / ML model in which joint inference is performed across multiple nodes (e.g., terminals and networks). For example, joint inference means that inference is performed jointly across multiple nodes, and for instance, a first part of the inference may be performed by a first node and the remainder of the inference may be performed by a second node.

[0190] For example, the operation described in the present disclosure below may be explained / interpreted based on an AI / ML model as shown in FIG. 21 below, even without separate mention (e.g., without explicit mention of being by / based on / for an AI / ML model).

[0191] Additionally, for example, unless specifically limited in the description of the present disclosure, an AI / ML model may correspond to a one-side model in which inference is performed entirely by a single node or a two-side model in which joint inference is performed by multiple nodes.

[0192] FIG. 21 is a diagram illustrating an example of a communication procedure based on an AI / ML model 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.

[0193] Referring to FIG. 21, for example, Step 1: In the description of the present disclosure below, signaling (e.g., information / data / channel / signal, etc.) or a set of signaling between a specific node (e.g., terminal, network, etc.) and another node may be interpreted as the signaling or a set of signaling of Step 1 used to perform an operation based on an AI / ML model, even if not otherwise mentioned. For example, it may correspond to training data for training (e.g., generation and / or reconstruction) the AI / ML model of FIG. 20, or to inference data used for inference of the AI / ML model, or to feedback to the AI / ML model, etc. For example, if signaling between nodes is not required prior to an operation based on an AI / ML model in the present disclosure, Step 1 may be omitted. For example, if a one-side model is used in the present disclosure, unidirectional / bidirectional signaling (set) in the present disclosure may correspond to the signaling of Step 1. Additionally, for example, when a two-side model is used in the present disclosure, unidirectional / bidirectional signaling in the present disclosure may correspond to one stage of signaling, and repetitive signaling operations may also correspond to one stage of signaling.

[0194] For example, in AI / ML model-based beam management (BM), when a base station predicts (e.g., infers) high-quality beam(s) based on an AI / ML model, the base station can receive quality / intensity information for multiple beams from a terminal. For example, also, when a terminal predicts (e.g., infers) high-quality beam(s) based on an AI / ML model, the terminal can receive multiple beams from the base station.

[0195] Step 2: In the description of the present disclosure below, operations (e.g., computation, selection, prediction, etc.) at a specific node (e.g., terminal, network, etc.) or common operations (e.g., computation, selection, prediction, etc.) at multiple nodes (e.g., terminal, network, etc.) may correspond to operations of Step 2 based on one or more functions in the functional framework of an AI / ML model, unless otherwise noted. For example, they may correspond to training (e.g., generation and / or reconstruction) of the AI / ML model of FIG. 20 or to inference of the AI / ML model. When a one-side model is used, operations performed by a single node in the present disclosure may correspond to operations of Step 2, and when a two-side model is used, common operations performed by multiple nodes in the present disclosure may correspond to operations of Step 2.

[0196] For example, in an AI / ML model-based BM, a base station can use quality / intensity information regarding multiple beams received from a terminal as inference data to predict (e.g., infer) high-quality beam(s) based on an AI / ML model. Additionally, for example, a terminal can measure multiple beams received from a base station and use the measurement results as inference data to predict (e.g., infer) high-quality beam(s) based on an AI / ML model.

[0197] Step 3: In the description of the present disclosure below, signaling (e.g., information / data / channel / signal, etc.) or a set of signaling between a specific node (e.g., terminal, network, etc.) and another node may be interpreted as the signaling or set of signaling of Step 3 generated as a result of an operation based on an AI / ML model, unless otherwise noted. For example, it may correspond to the output resulting from the inference of the AI / ML model of FIG. 20. If signaling between nodes is not required as a result of an operation based on an AI / ML model in the present disclosure, Step 3 may be omitted. If a one-side model is used in the present disclosure, unidirectional / bidirectional signaling (set) in the present disclosure may correspond to the signaling of Step 3. In addition, for example, when a two-side model is used in the present disclosure, unidirectional / bidirectional signaling in the present disclosure may correspond to three-stage signaling, and also repetitive signaling operation may correspond to three-stage signaling.

[0198] For example, in an AI / ML model-based BM, the base station may transmit beam(s) predicted based on the AI / ML model as candidates to the terminal so that the terminal can determine the optimal beam. Additionally, for example, the terminal may report the beam(s) predicted based on the AI / ML model to the base station to request the base station to transmit candidate beams as candidates for determining the optimal beam.

[0199] For example, in the present disclosure, "specific threshold" may mean a threshold that is predefined or (pre-)set by an upper layer (including the application layer) of a network, base station, or terminal. For example, in the present disclosure, "specific set value" may mean a value that is predefined or (pre-)set by an upper layer (including the application layer) of a network, base station, or terminal. For example, in the present disclosure, "set by the network / base station" may mean an action in which a base station sets to a UE (pre-) through upper layer RRC signaling, sets / signals to a UE through MAC CE, or signals to a UE through DCI.

[0200] For example, in the present disclosure, a message may be interpreted as being replaced by at least one of a control message, a data message, a signal, a data signal, and / or a control signal.

[0201] In the following description, various names are exemplary and may be considered to perform the same or similar functions (regardless of their names) based on the content described in each step.

[0279] 8 Random Access Procedure

[0280] Prior to the initiation of the physical random access procedure, layer 1 receives a set of SS / PBCH block indices from the upper layer and provides a set of corresponding RSRP measurements to the upper layer.

[0281] Prior to the initiation of a physical random access procedure, layer 1 may receive instructions from an upper layer to perform a Type-1 random access procedure as described in Section 8.1 or to perform a Type-2 random access procedure as described in Section 8.1.

[0282] Before initiating the physical random access procedure, layer 1 receives the following information from the upper layer:

[0283] - Setting of physical random access channel (PRACH) transmission parameters (PRACH preamble format, time resource, and frequency resource).

[0284] - Parameters for determining the root sequence and their cyclic shifts in the PRACH preamble sequence set (index for the logical root sequence table, cyclic shift (N CS ), and set type (unrestricted, restricted set A, or restricted set B)).

[0285] From a physical layer perspective, a Type-1 L1 random access procedure includes the transmission of a random access preamble (Msg1) in PRACH, a random access response (RAR) message (Msg2) with PDCCH / PDSCH, and, where applicable, the transmission of PUSCH scheduled by a RAR UL grant, and PDSCH for contention resolution.

[0286] From a physical layer perspective, a Type-2 L1 random access procedure includes the transmission of a random access preamble and a PUSCH (MsgA) in PRACH, the reception of a RAR message (MsgB) with a PDCCH / PDSCH, and, where applicable, the transmission of a PUSCH scheduled by a fallback RAR UL grant, and a PDSCH for contention resolution.

[0287] When a random access procedure is initiated by a PDCCH order for the UE, the PRACH transmission has the same SCS as the PRACH transmission initiated by the upper layer.

[0288] If the UE is set to two UL carriers for the serving cell and the UE detects a PDCCH order, the UE uses the UL / SUL indicator field value from the detected PDCCH order to determine the UL carrier for the corresponding PRACH transmission.

[0289] 8.1 Random Access Preamble

[0290] The physical random access procedure for the UE is triggered by a PRACH transmission request by the upper layer or a PDCCH order for the cell. The settings by the upper layer for PRACH transmission include the following:

[0291] - Configuration for PRACH transmission in a cell [TS 38.211].

[0292] - Preamble Index, Preamble SCS, P PRACH,target , corresponding RA-RNTI [TS 38.321] where applicable, and PRACH resources for the cell.

[0293] - If the UE transmits a PRACH with repetitions, for the PRACH transmission Number of preamble repetitions.

[0294] UE transmits power P PRACH,b,f,c (i) transmits PRACH from the cell using the selected PRACH format, and the indicated PRACH resource or For preamble iterations, use the same spatial filter Transmits from a determined set of resources.

[0295] For a Type-1 random access procedure, the UE is provided by ssb-perRACH-OccasionAndCB-PreamblesPerSSB with the number of SS / PBCH block indices associated with one PRACH occasion and the number of contention-based preambles R per SS / PBCH block index for each valid PRACH occasion.

[0296] In the case where a Type-2 random access procedure has a PRACH occasion of common configuration with a Type-1 random access procedure, the UE is provided with N, the number of SS / PBCH block indices associated with one PRACH occasion, by ssb-perRACH-OccasionAndCB-PreamblesPerSSB, and Q, the number of contention-based preambles per SS / PBCH block index per valid PRACH occasion, by msgA-CB-PreamblesPerSSB-PerSharedRO. PRACH transfers may be performed on a subset of PRACH occasions associated with the same SS / PBCH block index within an SSB-RO mapping cycle for a UE provided with a PRACH mask index by msgA-SSB-SharedRO-MaskIndex in accordance with [TS 38.321].

[0297] In a Type-2 random access procedure having a separate PRACH occasion configuration from a Type-1 random access procedure, the UE is provided with N, the number of SS / PBCH block indices associated with one PRACH occasion, and R, the number of contention-based preambles per SS / PBCH block index for each valid PRACH occasion, by msgA-SSB-PerRACH-OccasionAndCB-PreamblesPerSSB if provided, and ssb-perRACH-OccasionAndCB-PreamblesPerSSB otherwise.

[0298] For a random access procedure associated with a feature combination indicated by FeatureCombinationPreambles, the UE is provided with N, the number of SS / PBCH block indices associated with one PRACH opportunity, by msgA-SSB-PerRACH-OccasionAndCB-PreamblesPerSSB or ssb-perRACH-OccasionAndCB-PreamblesPerSSB, and S, the number of contention-based preambles per SS / PBCH block index per valid PRACH opportunity, by startPreambleForThisPartition and numberOfPreamblesPerSSB-ForThisPartition. PRACH transmission can be performed on a subset of PRACH opportunities associated with the same SS / PBCH block index within an SSB-RO mapping cycle for a UE that has been provided with a PRACH mask index by ssb-SharedRO-MaskIndex in accordance with [TS 38.321].

[0299] For a Type-1 random access procedure, or for a Type-2 random access procedure having a separate PRACH opportunity configuration from the Type-1 random access procedure, if N < 1, a single SS / PBCH block index is mapped to 1 / N consecutive valid PRACH opportunities, and R contention-based preambles with consecutive indices associated with the SS / PBCH block index for each valid PRACH opportunity start from preamble index 0. If N ≥ 1, R contention-based preambles with consecutive indices associated with the SS / PBCH block index n, 0 ≤ n ≤ N-1, for each valid PRACH opportunity are preamble index Starting from, here is provided by totalNumberOfRA-Preambles for a Type-1 random access procedure, or by msgA-TotalNumberOfRA-Preambles for a Type-2 random access procedure having a separate PRACH occasion configuration from a Type-1 random access procedure, and is an integer multiple of N.

[0300] In the case where a Type-2 random access procedure has a composition of pracha occasions common to a Type-1 random access procedure, if N < 1, a single SS / PBCH block index is mapped to 1 / N consecutive valid pracha occasions, and Q contention-based preambles with consecutive indices associated with the SS / PBCH block index for each valid pracha occasion start from preamble index R. If N ≥ 1, Q contention-based preambles with consecutive indices associated with the SS / PBCH block index n, 0 ≤ n ≤ N-1, for each valid pracha occasion are preamble index Starting from, here TotalNumberOfRA-Preambles is provided for Type-1 random access procedures.

[0301] For link recovery, the UE is provided with N SS / PBCH block indices associated with one PRACH opportunity by ssb-perRACH-Occasion in BeamFailureRecoveryConfig. For dedicated RACH configuration provided by RACH-ConfigDedicated, if cfra is provided, the UE is provided with N SS / PBCH block indices associated with one PRACH opportunity by ssb-perRACH-Occasion in the opportunities. If N < 1, one SS / PBCH block indices is mapped to 1 / N consecutive valid PRACH opportunities. If N ≥ 1, all N consecutive SS / PBCH block indices are associated with one PRACH opportunity.

[0302] The SS / PBCH block indices provided by ssb-PositionsInBurst of SIB1 or ServingCellConfigCommon are mapped to valid PRACH occasions in the following order according to the parameters described in [TS 38.211].

[0303] - First, the increasing order of the preamble index within a single pracing opportunity

[0304] - Second, the increasing order of the frequency resource index for frequency-multiplexed PRACH opportunities

[0305] - Third, the increasing order of the time resource index for time-multiplexed PRACH opportunities within the PRACH slot

[0306] - Fourth, the increasing order of the indices of the PRACH slots

[0307] The association period starting from frame 0 is the minimum number of integers within the set determined by the PRACH configuration period according to Table 3, and for PRACH occasions within the association period A value that ensures SS / PBCH block indices are mapped at least once, and UE is from SIB1 or the ssb-PositionsInBurst value of ServingCellConfigCommon Acquires. After an integer number of mapping cycles between the SS / PBCH block index and the PRACH occasion within the association period, If there exists a set of PRACH occasions or PRACH preambles that are not mapped to an SS / PBCH block index, the SS / PBCH block index is not mapped to that set of PRACH occasions or PRACH preambles. The association pattern period includes one or more association periods, and the pattern between PRACH occasions and SS / PBCH block indexes is determined to repeat at a maximum of 160 msec. If there are PRACH occasions that are not associated with an SS / PBCH block index after an integer number of association periods, they are not used for PRACH transmission.

[0308] For a PRACH transmission of a UE triggered by a PDCCH order, if the value of the random access preamble index field is not zero, the PRACH mask index field indicates a PRACH occasion for the PRACH transmission, which is associated with an SS / PBCH block index indicated by the SS / PBCH block index field of the PDCCH order, and if present, the cell indicator field indicates a cell for the PRACH transmission [TS 38.212]. The UE K by cellSpecificKoffset cell,offset If provided, the PRACH opportunity is slot n+2 μ ·Kcell,offset It follows, where n is T TA Assuming =0, it is the slot of the UL BWP for the PRACH transmission that overlaps with the end of the PDCCH order reception, and μ is the SCS configuration for the PRACH transmission. If the PDCCH reception for the PDCCH order contains two PDCCH candidates from two linked search space sets based on searchSpaceLinkingId, the last symbol of the PDCCH reception is the last symbol of the PDCCH candidate ending later. The PDCCH reception also contains two PDCCH candidates even if the UE does not need to monitor one of the two PDCCH candidates.

[0309] For a PRACH transfer triggered by an upper layer, if ssb-ResourceList is provided, the PRACH mask index is indicated by ra-ssb-OccasionMaskIndex, which indicates PRACH occasions for a PRACH transfer associated with the selected SS / PBCH block index.

[0310] PRACH opportunities are mapped consecutively for corresponding SS / PBCH block indices. The indexing of PRACH opportunities indicated by the mask index value is reset for every mapping cycle of consecutive PRACH opportunities for each SS / PBCH block index. The UE selects the PRACH opportunity indicated by the PRACH mask index value for the SS / PBCH block index designated for PRACH transmission in the first available mapping cycle.

[0311] For the indicated preamble index, the order of PRACH occasions is as follows:

[0312] - First, the increasing order of the frequency resource index for frequency-multiplexed PRACH opportunities.

[0313] - Second, the increasing order of the time resource index for time-multiplexed PRACH opportunities within the PRACH slot

[0314] - Third, the increasing order of indices for PRACH slots

[0315] For a PRACH transmission with preamble repetitions, a set is temporally consecutive, uses the same frequency resource, and is associated with one or more of the same SS / PBCH block indices. It consists of valid pracha occasions, and each SS / PBCH block index is associated with the same preamble index(es) in all valid pracha occasions within the set.

[0316] For a PRACH transmission with preamble repetitions, the time period starting from frame 0 is for each of the configured number of preamble repetitions It is the minimum integer number of association pattern periods such that at least one set of valid PRACH occasions per SS / PBCH block index can be determined within the period. The sets of valid PRACH occasions for each constructed preamble iteration are repeated for every period.

[0317] Within a time period, For PRACH transmission with preamble repetition For sets of valid PRACH opportunities

[0318] - The first valid PRACH occasion of the first set is the first valid PRACH occasion and

[0319] - If present, the first valid PRACH occasion of subsequent sets is determined according to the order of valid PRACH occasions.

[0320] First, the increasing order of the frequency resource index for frequency-multiplexed PRACH opportunities.

[0321] Second, the increasing order of the time resource index for time-multiplexed PRACH opportunities.

[0322] Here, for each frequency resource index for frequency-multiplexed PRACH opportunities

[0323] - The first valid PRACH occasion of the first set is the first valid PRACH occasion and

[0324] - If present, the first valid PRACH occasion of subsequent sets is

[0325] - If TimeOffsetBetweenStartingRO is provided, it is after TimeOffsetBetweenStartingRO valid PRACH occasions that are temporally consecutive from the first valid PRACH occasion of the previous set, where each PRACH occasion is associated with the same SS / PBCH block index(es) and each SS / PBCH block index is associated with the same preambles.

[0326] - If TimeOffsetBetweenStartingRO is not provided, it is after the PRACH occasions for the previous set.

[0327] For a PRACH transfer triggered by a request from an upper layer, if csirs-ResourceList is provided, the value of ra-OccasionList [TS 38.331] indicates a list of PRACH occasions for a PRACH transfer associated with a selected CSI-RS index indicated by csi-RS. The indexing of PRACH occasions indicated by ra-OccasionList is reset by association pattern period.

[0330] All PRACH opportunities are valid for the paired spectrum or supplementary uplink band.

[0331] Regarding the unpaired spectrum,

[0333] - - The candidate SS / PBCH block index corresponds to the SS / PBCH block index provided by SIB1 or ServingCellConfigCommon's ssb-PositionsInBurst.

[0334] - If the UE is provided with tdd-UL-DL-ConfigurationCommon, the PRACH opportunity within the PRACH slot is valid in the following cases:

[0335] - - If it is within the uplink symbol, or

[0336] - - It does not precede the SS / PBCH block within the PRACH slot, and at least N after the last downlink symbol gap Starting from the symbol, and at least N after the last SS / PBCH block symbol gap Starting from the symbol, here N gap It is provided in Table 4, and if channelAccessMode= “semiStatic” is provided, it does not overlap with a set of consecutive symbols before the next channel occupancy time, during which no transmissions should occur, as described in [TS 37.213].

[0337] - - - The candidate SS / PBCH block index corresponds to the SS / PBCH block index provided by SIB1 or ServingCellConfigCommon's ssb-PositionsInBurst.

[0338] For the preamble format B4 [TS 38.211], N gap =0.

[0341] When a random access procedure is initiated by a PDCCH order, the UE transmits a PRACH at a selected PRACH occasion, as described in [TS 38.321], if requested by an upper layer, wherein the time between the last symbol of the PDCCH order reception and the first symbol of the PRACH transmission is N T,2 +T BWPswitchDelay +Δ Delay +T switch +T SSB +Δ RF / BB preparation Greater than or equal to msec, here

[0342] - N T,2 is the time length of the N2 symbol corresponding to the PUSCH preparation time for UE processing capability 1, assuming μ corresponds to the minimum SCS setting between the SCS setting of the PDCCH order and the SCS setting of the corresponding PRACH transmission [TS 38.214]

[0343] - If the UL BWP is not changed, or if the cell indicator field of the PDCCH order indicates a non-serving cell [TS 38.212], T BWPswitchDelay =0, and if not, T BWPswitchDelay is defined in [TS 38.133].

[0344] - Δ Delay =0.5 msec is for FR1 and Δ Delay =0.25 msec is for FR2.

[0345] - T switch is the switching gap duration defined in [TS 38.214].

[0346] - If the cell indicator field of the PDCCH order indicates a serving cell, or if the cell indicator field does not exist, T SSB =0, and if not, T SSB is defined in [TS 38.133].

[0348] For PRACH transmission using 1.25 kHz or 5 kHz SCS, the UE determines N2 by assuming SCS setting μ=0.

[0349] For single-cell operation, or for operation with a contiguous set of carriers within the same frequency band, or for operation with a non-contiguous set of carriers within the same frequency band where the UE is not provided with intraBandNC-PRACH-simulTx-r17, the UE

[0351] - If the first or last symbol of the PRACH transmission in the first slot is separated from the last or first symbol of the PUSCH / PUCCH / SRS transmission in the second slot by less than N symbols, respectively, PRACH and PUSCH / PUCCH / SRS are not transmitted.

[0352] - For a PRACH transmission with a preamble repetition, if the UE does not indicate capability-XYZ, if the first or last symbol of the first repetition of PRACH in the first slot is separated from the last or first symbol of the second repetition of PRACH in the second slot by less than N symbols, the UE does not transmit the first repetition of PRACH and the second repetition of PRACH; otherwise, the UE transmits the first repetition of PRACH and the second repetition of PRACH.

[0353] Here, N=2 is for μ=0 or μ=1, N=4 is for μ=2 or μ=3, N=16 is for μ=5, N=32 is for μ=6, and μ is the minimum SCS setting between the SCS setting for an uplink BWP with PRACH and the SCS setting for an uplink BWP with PUSCH / PUCCH / SRS transmissions. For a PUSCH transmission with repetition type B, this applies to each actual repetition for the PUSCH transmission [TS 38.214].

[0354] For example, a random access procedure in 38.321 may be initiated.

[0420] For example, PUCCH in 38.213 may be initiated.

[0421] 9.2.1 PUCCH resource set

[0422] If the UE does not have a dedicated PUCCH resource setting provided by the PUCCH-ResourceSet in PUCCH-Config, the PUCCH resource set is For the transmission of HARQ-ACK information on PUCCH in the initial uplink BWP having PRBs, it is provided by PUCCH-ResourceCommon via an index for the row in Table 5. For operation in FR2-2, nrofPRBs provided by PUCCH-ConfigCommon is also N for the PUCCH resource set. RB You can provide the number of RBs, and if not, N RB =1.

[0423] The PUCCH resource set contains 16 resources, each consisting of the PUCCH format, first symbol, duration, and PRB offset. , and correspond to a set of cyclic shift indices for PUCCH transmission.

[0424] If useInterlacePUCCH-PUSCH is not provided in BWP-UplinkCommon, the UE transmits PUCCH using frequency hopping; otherwise, the UE transmits PUCCH without frequency hopping.

[0425] For PUCCH resources with PUCCH format 1 in Table 5, an orthogonal cover code with index 0 is used, except where index 3, 7, or 11 is indicated by pucch-ResourceCommon and useInterlacePUCCH-PUSCH is provided by BWP-UplinkCommon.

[0426] The UE transmits PUCCH using the same spatial domain transmission filter as for PUSCH transmissions scheduled by the RAR uplink grant.

[0427] FIG. 22 illustrates an example of a PUCCH resource according to one embodiment of the present disclosure. The embodiment of FIG. 22 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0428] Referring to FIG. 22, a slot can be defined in the time domain. For example, some resource areas within the slot may be configured as PUCCH resources in symbol units as shown. For example, the location and number of the PUCCH resources may be cell-specifically set / instructed by the base station through the SIB's pucch-ResourceCommon, using one of the index values ​​0 to 15 of Table 5, and the terminal may transmit control information from the corresponding resource based on the configuration.

[0429] For example, the parameters constituting the existing NR initial PUCCH resource set (e.g., the PUCCH resource set prior to the dedicated PUCCH resource setting) can be defined as shown in Table 5. For example, the base station can specifically set / instruct one of the index values ​​0 to 15 in Table 5 through the SIB's pucch-ResourceCommon.

PUCCH= 0, 1, 2, … , 15) can be configured (by the base station). For example, if the base station sets / instructs index 0, 1, or 4 through the SIB, the parameter values ​​for each of the 16 different PUCCH resources can be configured as shown in Table 6.

[0435] For example, in existing NR, an initial PUCCH resource set intended for wide-band (WB) UEs could not be directly used by narrow-band (NB) UEs, so an initial PUCCH resource set for NB UEs could be defined separately. Therefore, considering a situation where WB UEs and NB UEs coexist within the same cell, the present disclosure proposes a method for configuring an initial PUCCH resource set for NB UEs so that WB UEs can share and use it.

[0436] Recently, in 5G mobile communication systems, a structure is being considered in which a common PUCCH resource is defined at each edge of the initial bandwidth part (BWP) of the UL for initial uplink control transmission.

[0437] However, in an environment where narrowband UEs and wideband UEs coexist, different UL initial BWPs may be set depending on the bandwidth characteristics of the terminals, and consequently, the following problems occur.

[0438] First, when narrowband UEs and wideband UEs use different UL initial BWPs, there is a problem in that different common PUCCH resources are separately defined and used in correspondence with each UL initial BWP.

[0439] Second, as different common PUCCH resources are used depending on the terminal type within the same cell, the distribution and redundancy of common resources may occur, which may reduce resource utilization efficiency.

[0440] Third, as common PUCCH resources are separated and operated by terminal type, there is a problem of increased complexity in terms of system design and operation.

[0441] To solve the above problem, the present disclosure provides a method for efficiently sharing common PUCCH resources between a narrowband UE and a broadband UE. Specifically, the device receives broadband BWP-related settings from a base station and receives a random access-related message based on the broadband BWP-related settings. Subsequently, the device performs a PUCCH transmission for the random access-related message. At this time, instead of using a PUCCH resource separately defined corresponding to the broadband BWP, the PUCCH transmission is performed on one of the PUCCH resources configured based on at least one narrowband BWP-related setting. For example, the present disclosure can integrate resource structures between terminal types by utilizing common PUCCH resources defined based on the narrowband BWP even in a broadband BWP-based operating environment.

[0442] The methods proposed in this disclosure may consider defining a single initial PUCCH resource set table in the spec and using it in common for both NB UE and WB UE.

[0443] 1. Method for defining an initial PUCCH resource set for WB UEs based on multiple initial PUCCH resource sets for NB UEs

[0444] FIG. 23 illustrates an example of an NB BWP and a WB BWP according to an embodiment of the present disclosure. The embodiment of FIG. 23 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0445] Referring to FIG. 23, a single WB BWP may be configured within the channel bandwidth (CBW), and the WB BWP may be configured to include NB BWP #1 to NB BWP #4. Each NB BWP occupies a frequency range distinct from one another within the WB BWP and may be formed by dividing a portion of the WB BWP. For example, the WB BWP may be defined as a BWP covering a relatively wide frequency band, and multiple NB BWPs, such as NB BWP #1 to NB BWP #4, may be hierarchically configured within the WB BWP. For example, the CBW refers to the entire frequency range available in the system, and the WB BWP and NB BWPs may be defined as logical or configurable frequency ranges configured within the CBW.

[0446] For example, first, a method may be considered to define an initial PUCCH resource set for WB UE based on multiple initial PUCCH resource sets for NB UE. Here, for example, multiple initial UL BWPs for NB may constitute a single initial UL BWP for WB. For example, a base station may be defined to indicate an initial PUCCH resource set index to be used commonly by multiple initial UL BWPs for NBs, or to indicate one initial PUCCH resource set index for an initial UL BWP for a specific NB (e.g., an NB located at the lowest (highest) frequency) and set the remaining initial UL BWPs for NBs to reuse that information, or to indicate an initial PUCCH resource set index independent for each initial UL BWP for NBs.

[0447] For example (as a specific proposed method), based on the index of the initial PUCCH resource set for the NB configured / instructed by the base station, the initial PUCCH resource to be used by the NB UE (e.g., r PUCCH) M can be configured. For example, (e.g., M=16), assuming that N NB initial UL BWPs are included within the corresponding WB initial UL BWP, if the WB UE is defined to use all initial PUCCH resources configured for the NB UE, then a total of N×M initial PUCCH resources (e.g., r PUCCH ) can be configured. For example, if configured in this way, additional actions need to be defined in addition to the action of the base station indicating the initial PUCCH resource index to be actually used to the WB UE using the PRI (PUCCH resource indicator) field.

[0448] For example (as an example of the operation mentioned above), a DCI format transmitting the PRI field (e.g., a DCI format scheduling Msg4 PDSCH) may be defined such that a [log2N] bit DCI field is separately defined (e.g., a narrow band indicator) to indicate one of N NB indices, and the remaining information is defined to indicate one of M initial PUCCH resource indices through a PRI (PUCCH resource indicator) field composed of [log2M] bits. For example (or), a method can also be considered in which the PRI field is extended to [log2(N×M)] bits to directly indicate one of a total of N×M initial PUCCH resources. Here, for example, r PUCCHThe index can be defined to fill up to a total of N×M-1 by first filling M from 0 to M-1 within the lowest NB, and then filling M from M to 2M-1 within the next lowest NB.

[0449] For example, based on the location of the Msg4 PDSCH resource transmitted from the base station and / or the Msg3 PUSCH resource transmitted by the WB UE, the terminal may be defined to implicitly select an NB index, and the actual initial PUCCH resource within the corresponding NB may be defined to be indicated by the base station through the PRI field. For example, as an example of the terminal implicitly selecting the NB index, it may be defined that the terminal selects an NB index within the UL initial BWP corresponding to the lowest (highest) PRB index of the Msg4 PDSCH resource transmitted from the base station within the DL initial BWP. For example, as an example of a terminal implicitly selecting an NB index, it can be defined that the terminal selects the NB index where the lowest (highest) PRB index of the Msg3 PUSCH resource transmitted by the terminal within the UL initial BWP is located, according to the RAR UL grant provided by the base station.

[0450] For example, the base station may be configured to indicate the NB index via a RAR UL grant. For example (specifically), if an operation is considered to distinguish whether it is an NB UE or a WB UE through preamble partitioning during the step of transmitting the Msg1 preamble, the base station may be configured to indicate the NB index via a RAR UL grant when it receives the Msg1 preamble and determines that it was transmitted from a WB UE. For example, the UE may subsequently be configured to perform the transmission of Msg.3 PUSCH and / or the transmission of HAQR-ACK for Msg.4 PDSCH using the NB initial UL BWP corresponding to the NB index configured / indicated via RAR.

[0451] For example, based on the index of the initial PUCCH resource set for the NB configured / instructed by the base station, the initial PUCCH resources to be used by the NB UE (e.g., r PUCCH M ) can be configured. (e.g., M=16) Subsequently, assuming that N NB initial UL BWPs are included within the corresponding WB initial UL BWP, the WB UE selects only some M of the all initial PUCCH resources configured for the NB UE to use as initial PUCCH resources (e.g., r PUCCH It can be defined to be used as ). For example, if defined in this way, it may be sufficient to indicate the PRI (PUCCH resource indicator) field to indicate the initial PUCCH resource index that the WB UE will actually use.

[0452] For example, selecting some M of all initial PUCCH resources configured for an NB UE, for instance, initial PUCCH resources defined in N initial UL BWPs for NBs (e.g., r PUCCH It can be defined by selecting K each from ) such that N×K equals M. For example (specifically), when M=16 and N=4, the initial PUCCH resource for each NB UE (e.g., r PUCCH It can be defined to select 4 resources (with different intra slot hopping directions) from among ).

[0453] For example, the initial PUCCH resource defined in the lowest NB UL BWP (e.g., r PUCCH Select M / 2 resources that perform intra-slot hopping from a low-frequency PRB to a high-frequency PRB among them, and the initial PUCCH resource defined in the highest NB UL BWP (e.g., r PUCCH Select M / 2 resources that perform intra-slot hopping from a high-frequency PRB to a low-frequency PRB among them to obtain a total of M initial PUCCH resources (e.g., r PUCCH ) can be defined as a resource for WB UE.

[0454] For example (additionally), the initial PUCCH resource allocated by the base station for the WB UE through higher layer signaling (e.g., SIB, etc.) (e.g., r PUCCH It can be defined to separately specify the number. For example (as an example based on the above example), the base station provides the WB UE with a total of N×M initial PUCCH resources (e.g., r PUCCH It may instruct the WB UE to use ), or the base station may instruct the UE to use a total of M initial PUCCH resources (e.g., r PUCCH It may also be instructed to use. For example, the terminal may be defined to operate by applying one of the proposed methods based on the corresponding configuration information.

[0455] For example, similar to the proposed method above, a method of setting initial PUCCH resources differently for each SSB beam (group) index can also be considered. For instance, when a base station specifies an initial PUCCH resource set index, it may provide it independently for each SSB beam (group) index. For instance, the base station may provide a single representative initial PUCCH resource set index, and in the absence of separate instructions, all SSB beam (group) indices may be defined to share that representative initial PUCCH resource set index. For example, if a base station provides a separate initial PUCCH resource set index only to some SSB beam (group) indices, it can be defined so that only the provided SSB beam (group) indices form a separate initial PUCCH resource set, and the SSB beam (group) indices that are not provided share that representative initial PUCCH resource set index.

[0456] 2. Method to configure / instruct the initial PUCCH resource set for WB UE differently based on the number of Msg.4 HARQ-ACK PUCCH transmissions

[0457] For example, the base station may select one of M resources as the initial PUCCH resource to be used when the WB UE transmits the first Msg.4 HARQ-ACK PUCCH, as in the methods proposed above. Here, for example, if the terminal transmits the Msg.4 HARQ-ACK PUCCH using the resource but the base station fails to receive it, the base station may consider a method of setting the initial PUCCH resource for the next Msg.4 HARQ-ACK PUCCH from among more resources than the existing M, or setting the initial PUCCH resource to be used by the WB UE to occupy more of the time / frequency domain. By configuring it this way, frequency diversity can be obtained from the initial PUCCH resources used when transmitting the next Msg.4 HARQ-ACK PUCCH compared to when transmitting the first Msg.4 HARQ-ACK PUCCH, or more time / frequency resources can be used, thereby improving coverage.

[0458] For example (as a specific example), if the base station instructed the WB UE to use one of M specific initial PUCCH resources when transmitting the first Msg.4 HARQ-ACK PUCCH, the base station may instruct the UE to use one of the resources increased by an integer multiple of M for the initial PUCCH resources when transmitting the next Msg.4 HARQ-ACK PUCCH. For example, when transmitting the second Msg.4 HARQ-ACK PUCCH, one of 2×M resources can be selected, and when transmitting the third Msg.4 HARQ-ACK PUCCH, one of 3×M resources can be selected. Here, for example, if the number of NBs is N, the maximum value of the initial PUCCH resources that the base station can select can be N×M. Here, for example, the base station may be configured to increase the total resource pool for instructing the WB UE in units of initial PUCCH resources used by the NB UE, or, the base station may be defined so that initial PUCCH resources included in the NB index for which it did not previously provide for the transmission of the Msg.4 HARQ-ACK PUCCH may be selected with higher priority. In this case, one of the methods proposed in 1. (e.g., 1. a method of defining a set of initial PUCCH resources for the WB UE based on a set of initial PUCCH resources for multiple NB UEs) may also be applied for instructing the increased resources.

[0459] For example, if the base station instructed the WB UE to use one of the M initial PUCCH resources included in a specific NB index when transmitting the first Msg.4 HARQ-ACK PUCCH, the base station may instruct the UE to use one of the M initial PUCCH resources included in a different NB index other than the one in question when transmitting the next Msg.4 HARQ-ACK PUCCH. For example, if the number of NBs is N, the base station may instruct to always use one of M NBs included in different NB indices during the transmission of a total of N Msg.4 HARQ-ACK PUCCHs, and then when using the next Msg.4 HARQ-ACK PUCCH, the base station may instruct to use one of M NBs included in a specific NB index that was set when the first Msg.4 HARQ-ACK PUCCH was transmitted.

[0460] For example, if the base station instructs the WB UE to transmit the initial PUCCH resource using a single PRB when transmitting the first Msg.4 HARQ-ACK PUCCH, the base station may instruct the UE to transmit the initial PUCCH resource using multiple PRBs when transmitting the next Msg.4 HARQ-ACK PUCCH; to this end, the base station may separately set / instruct an explicit number of PRBs along with the initial PUCCH resource index. Here, for example, when occupying multiple PRBs, the PUCCH sequence may be defined to be transmitted repeatedly in the frequency domain. For example, (or), if the base station instructs the WB UE to transmit the initial PUCCH resource only once in the time domain (e.g., to occupy x OFDM symbols) when transmitting the first Msg.4 HARQ-ACK PUCCH, the base station may instruct the WB UE to transmit the initial PUCCH resource repeatedly y times in the time domain (e.g., to occupy x*y OFDM symbols) when transmitting the next Msg.4 HARQ-ACK PUCCH.

[0461] To solve the above problem, the present disclosure provides a method for efficiently sharing common PUCCH resources between a narrowband UE and a broadband UE. Specifically, the device receives broadband BWP-related settings from a base station and receives a random access-related message based on the broadband BWP-related settings. Subsequently, the device performs a PUCCH transmission for the random access-related message. At this time, instead of using a PUCCH resource separately defined corresponding to the broadband BWP, the PUCCH transmission is performed on one of the PUCCH resources configured based on at least one narrowband BWP-related setting. For example, the present disclosure can integrate resource structures between terminal types by utilizing common PUCCH resources defined based on the narrowband BWP even in a broadband BWP-based operating environment.

[0462] According to the present disclosure, the following effects can be obtained.

[0463] First, since narrowband UEs and broadband UEs can share the same common PUCCH resources, redundant definitions of common PUCCH resources can be prevented and resource utilization efficiency can be improved.

[0464] Second, since common PUCCH resources can be integrated and operated regardless of terminal type, the complexity of system design and operation can be reduced.

[0465] Third, since various terminals can be supported based on the same resource structure, the scalability and compatibility of the system can be improved.

[0466] Fourth, through the efficient sharing of common PUCCH resources, the stability of uplink control signal transmission and resource utilization can be improved simultaneously.

[0467] In summary, by allowing narrowband and wideband UEs to share a common PUCCH resource, resource redundancy can be reduced and system efficiency improved.

[0468] For example, the dynamic indication (signaling) method mentioned in the proposed method above may be set / instructed per cell (or cell group) or per UE (or UE group).

[0469] In this disclosure, ' / ' may mean 'and', 'or', or 'and / or' depending on the context. For example (also), since examples of the proposed methods described above may also be included as one of the implementation methods of this disclosure, it is evident that they may be considered as a type of proposed method. For example (also), the proposed methods described above may be implemented independently, but may also be implemented in the form of a combination (or merger) of some proposed methods. Rules may be defined so that information on whether the proposed methods are applied (or information on the rules of the proposed methods) is communicated by a base station to a terminal via a predefined signal (e.g., a physical layer signal or an upper layer signal). The upper layer may include one or more of functional layers such as, for example, MAC, RLC, PDCP, RRC, and SDAP.

[0470] Methods, embodiments, or descriptions for implementing the method proposed in this disclosure may each be applied separately, or one or more methods (or embodiments or descriptions) may be applied in combination.

[0471] For example, the base station can use BS monostatic sensing mode. For example, the base station can use UE-BS bistatic sensing mode. For example, the base station can use a combination of BS monostatic sensing mode and UE-BS bistatic sensing mode (e.g., joint / hybrid).

[0472] For example, the sensing results used in the present disclosure (e.g., LOS information obtained by sensing measurement) may utilize sensing results obtained from non-3GPP sensing, such as radar / camera / lidar, as well as 3GPP sensing using 3GPP signals. For example, parameters such as thresholds and specific times used in the procedure may also be set differently depending on the type of sensor used (e.g., 3GPP sensing or non-3GPP sensing).

[0473] For example, in the above procedure, the serving base station may trigger a 3GPP sensing operation based on non-3GPP sensing results. For example, if the LOS probability decreases based on the non-3GPP sensing results, a 3GPP sensing operation may be performed to obtain more accurate sensing results. For example, conversely, a non-3GPP sensing operation may be triggered based on 3GPP sensing results. For example, this may be configured by considering the difference in accuracy between the 3GPP sensing operation and the non-3GPP sensing operation, as well as the required current consumption. For example, additionally, this operation may be used as a trigger condition for a sensing operation between the serving base station and the neighbor base station.

[0474] Combinations of various embodiments of the present disclosure may be applied differently depending on the payload type of the satellite (e.g., regenerative payload or transparent payload).

[0476] For example, in the embodiments of the present disclosure, the TDD setting and utilization are not limited to the TDD band, and can be extended to combinations of the FDD band and / or specific DL band and / or UL band.

[0477] For example, in an embodiment of the present disclosure, a base station or network node may be a satellite. For example, a base station or network node may be associated with a transparent payload. For example, a base station or network node may be associated with a regenerated payload.

[0478] A combination of embodiments of the present disclosure may operate in conjunction with each other.

[0479] Various embodiments of the present disclosure may be applied differently depending on the link type (DL, UL, SL) and / or the data type (SIB, group cast, unicast) and / or the search space type (CSS (common search space), USS (UE-specific search space)) where the scheduling PDCCH is detected and / or the base station node type and / or altitude and / or whether there is a power constraint. For example, a combination of various embodiments of the present disclosure may be applied only when involved in SIB transmission.

[0480] For example, in the present disclosure, the machine learning model may be an AI / ML model.

[0481] For example, in the present disclosure, a base station or network may be a TRP and / or an NB and / or an AMF and / or a (system) core. For example, in the present disclosure, an NB may be an AMF and / or a (system) core. For example, in the present disclosure, a system core may be an AMF and / or a (system) core.

[0482] For example, in the present disclosure, a sensing signal may be interpreted as having the same meaning as a sensing reference signal.

[0483] For example, in the present disclosure, sensing data may be interpreted as having the same meaning as sensing measurement data or sensing measurement report.

[0484] For example, the embodiments of the present disclosure may be extended to all of the above six sensing scenarios. For example, the embodiments of the present disclosure may be applicable to all of the above six sensing scenarios.

[0485] For example, the methods proposed in this disclosure can be applied to both 3GPP sensing data and non-3GPP sensing data.

[0486] For example, in the present disclosure, sensing data may be data derived by a sensing radio measurement entity based on radio signals (e.g., reflected, refracted, diffracted) affected by an object or environment of interest for the purpose of sensing. For example, this data may be raw measurements and may optionally be further processed within the sensing radio measurement entity. For example, the sensing data may include at least one of 3GPP sensing data or non-3GPP sensing data.

[0487] For example, in the present disclosure, 3GPP sensing data is data obtained from 3GPP radio signals that have been affected (e.g., reflected, refracted, diffracted) by an object or environment of interest for the purpose of sensing, and may optionally be processed within a 5G system.

[0488] For example, in the present disclosure, non-3GPP sensing data may be data provided by a non-3GPP sensor (e.g., video, LiDAR, sonar) regarding an object or environment of interest for the purpose of sensing.

[0489] For example, in the present disclosure, 5G / 6G radio sensing may be a 5GS / 6GS function that provides a function to acquire information about the characteristics of an environment and / or objects within the environment (e.g., shape, size, orientation, speed, location, distance, relative movement between objects, etc.) using NR radio frequency signals, and may, in some cases, be extended by information generated through a previously defined function in the EPC and / or E-UTRAN.

[0490] For example, in the present disclosure, sensing auxiliary information may be information provided to a 5G system from a trusted third party and may be used to support the derivation of sensing results. This information may not include 3GPP sensing data. For example, examples of sensing auxiliary information may include map information, location information, a UE identifier (ID) attached to or located near a sensing target, UE location information, UE velocity information, etc.

[0491] For example, in the present disclosure, sensing context information may be information that a 5G / 6G system exposes to a trusted third party along with the sensing results, and may provide context regarding the conditions under which the sensing results were derived. This information may not include 3GPP sensing data. For example, examples of sensing context information may include map information, location information, time of capture, UE location, and ID. This context information may be required in scenarios where the sensing results need to be combined with data from other sources outside of 5GS.

[0492] For example, in the present disclosure, a sensing group may be a set of sensing transmitters and sensing receivers whose locations are known and capable of synchronously collecting sensing data.

[0493] For example, in the present disclosure, a sensing receiver may be an entity that receives a sensing signal used by a sensing service in operation. The sensing receiver may be a RAN node or part of a UE. The sensing receiver may be located in the same entity as the sensing transmitter or in a different entity.

[0494] For example, in the present disclosure, the sensing result may be processed 3GPP sensing data requested by a service consumer.

[0495] For example, in the present disclosure, a sensing signal may be a transmission signal on a 3GPP radio interface that can be used for sensing purposes. For example, this definition may refer to NR radio frequency signals and, in some cases, may be extended to information generated from existing functions of the EPC and / or E-UTRAN.

[0496] For example, a sensing transmitter may be an entity that transmits a sensing signal used by a sensing service in an operation. A sensing transmitter may be part of a RAN node or a UE. A sensing transmitter may be located in the same entity as a sensing receiver or in a different entity.

[0497] For example, the target sensing service area may be an orthogonal coordinate location area that satisfies a specific sensing service quality and is to be sensed by deriving the characteristics of the environment and / or objects within the environment from 3GPP radio signals that have been affected (e.g., reflected, refracted, diffracted). This may include both indoor and outdoor environments.

[0498] For example, the present disclosure may be applied to base stations (e.g., TRP) and / or terminal monostatics. For example, the present disclosure may also be applied to base station-base station (e.g., TRP-TRP), base station-UE (e.g., TRP-UE), UE-base station (e.g., UE-TRP), and / or UE-UE bistatics.

[0499] For example, in the present disclosure, "specific threshold" may mean a threshold that is predefined or (pre-)set by an upper layer (including the application layer) of a network, base station, or terminal. For example, in the present disclosure, "specific set value" may mean a value that is predefined or (pre-)set by an upper layer (including the application layer) of a network, base station, or terminal. For example, in the present disclosure, "set by the network / base station" may mean an action in which a base station sets to a UE (pre-) through upper layer RRC signaling, sets / signals to a UE through MAC CE, or signals to a UE through DCI.

[0500] For example, in the present disclosure, a message may be interpreted as being replaced by at least one of a control message, a data message, a signal, a data signal, and / or a control signal.

[0501] For example, in this disclosure, various names are exemplary and may be replaced or considered as other names performing the same or similar functions based on the content described in each step (regardless of the name).

[0502] For example, in the present disclosure, the bandwidth part (BWP) may be replaced with a bandwidth setting set or a wireless resource set, etc.

[0503] For example, in the present disclosure, the wireless resource profile exemplified may be applied as a BWP (bandwidth part), a bandwidth setting set, a wireless resource set, etc.

[0587] To solve the above problem, the present disclosure provides a method for efficiently sharing common PUCCH resources between a narrowband UE and a broadband UE. Specifically, the device receives broadband BWP-related settings from a base station and receives a random access-related message based on the broadband BWP-related settings. Subsequently, the device performs a PUCCH transmission for the random access-related message. At this time, instead of using a PUCCH resource separately defined corresponding to the broadband BWP, the PUCCH transmission is performed on one of the PUCCH resources configured based on at least one narrowband BWP-related setting. For example, the present disclosure can integrate resource structures between terminal types by utilizing common PUCCH resources defined based on the narrowband BWP even in a broadband BWP-based operating environment.

[0588] According to the present disclosure, the following effects can be obtained.

[0589] First, since narrowband UEs and broadband UEs can share the same common PUCCH resources, redundant definitions of common PUCCH resources can be prevented and resource utilization efficiency can be improved.

[0590] Second, since common PUCCH resources can be integrated and operated regardless of terminal type, the complexity of system design and operation can be reduced.

[0591] Third, since various terminals can be supported based on the same resource structure, the scalability and compatibility of the system can be improved.

[0592] Fourth, through the efficient sharing of common PUCCH resources, the stability of uplink control signal transmission and resource utilization can be improved simultaneously.

[0593] In summary, by allowing narrowband and wideband UEs to share a common PUCCH resource, resource redundancy can be reduced and system efficiency improved.

[0614] FIG. 28 illustrates a signal processing circuit for a transmission signal according to one embodiment of the present disclosure. The embodiment of FIG. 28 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, suggestions, methods, and / or operations of the embodiments may be omitted.

[0615] Referring to FIG. 28, 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 operation / function of FIG. 28 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 27. The hardware elements of FIG. 28 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 27. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 27. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 27, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 27.

[0616] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 28. Here, the codeword is an encoded bit sequence of an information block. The information block may include a transmission block (e.g., UL-SCH transmission block, DL-SCH transmission block). The wireless signal can be transmitted through various physical channels (e.g., PUSCH, PDSCH).

[0617] Specifically, a codeword can be converted into a scrambled bit sequence by a scrambler (1010). The scrambled sequence used for scrambling is generated based on an initialization value, which may include ID information of a 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 an N*M precoding matrix W. 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 the complex modulation symbols. Additionally, the precoder (1040) can perform precoding without performing transform precoding.

[0618] A resource mapper (1050) can map the modulation symbols of each antenna port to a time-frequency resource. The time-frequency resource may include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. A signal generator (1060) generates a radio signal from the mapped modulation symbols, and the generated radio signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) may include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0619] The signal processing process for a received signal in a wireless device can be configured as the inverse of the signal processing process (1010–1060) of FIG. 28. For example, a wireless device (e.g., 100, 200 in FIG. 27) can receive a wireless signal from the outside through an antenna port / transceiver. The received wireless signal can be converted into a baseband signal through a signal restorer. To this end, the signal restorer may include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a Fast Fourier Transform (FFT) module. Subsequently, the baseband signal can be restored into a codeword through a resource de-mapper process, a postcoding process, a demodulation process, and a de-scrambling process. The codeword can be restored into the original information block 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.
