[0046] FIG. 1 illustrates a device-to-device communication procedure according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure.

[0047] Referring to FIG. 1, in step S101, a first device and a second device can perform synchronization. For example, the first device can be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device can be a base station, a network, a RAN node, an NTN node / cell, a TRP, a terminal and / or at least one of the devices proposed in the present disclosure. For example, the first device can perform an initial cell search operation. For example, the first device can detect at least one synchronization signal transmitted by the second device according to a predefined rule. Here, for example, the synchronization signal can include a plurality of synchronization signals classified according to a structure or purpose (e.g., a primary synchronization signal, a secondary synchronization signal, etc.). Through this, the first device can identify the boundaries of the frame, subframe, time unit, slot, and / or symbol of the second device, and the first device can obtain information about the second device (e.g., a cell identifier).

[0048] In step S103, the first device can obtain system information transmitted by the second device. For example, the system information may include information related to the properties, characteristics, and / or capabilities of the second device required to connect to the second device and use the service. For example, the system information may be classified according to content (e.g., whether it is essential for connection), transmission structure (e.g., the channel used, whether it is provided on-demand), etc. For example, the system information may be classified into a master information block (MIB) and a system information block (SIB). For example, if necessary, the first device may transmit a signal requesting system information before receiving the system information. For example, the request and provision of system information may be performed after a random access procedure described below.

[0049] In step S105, the first device and the second device can perform a random access procedure. For example, the first device can transmit and / or receive at least one message (e.g., a random access preamble, a random access response message, etc.) for the random access procedure based on information related to a random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device can transmit a preamble (e.g., Msg1) through the random access channel, the first device can receive a random access response message (e.g., Msg2), the first device can transmit a message (e.g., Msg3) including information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device can receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be sent and received as one message (e.g., MsgA), and / or Msg2 and Msg4 can be sent and received as one message (e.g., MsgB).

[0050] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer that controls a connection (e.g., a radio resource control (RRC) layer), a layer that handles mapping between logical channels and transport channels (e.g., a media access control (MAC) layer), a layer that handles physical channels (e.g., a physical (PHY) layer), etc. For example, the first device and the second device may perform at least one of signaling for establishing a connection, signaling for determining settings related to communication, and / or signaling for indicating allocated resources. For example, the control information may be signaled / transmitted via a control channel. For example, the control information and / or the control channel may be used to schedule at least one of data, a data channel (e.g., a shared channel), and / or control information on the data channel.

[0051] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process, transmit, and / or receive data based on signaling of control information. For example, when transmitting data, the first device or the second device may perform at least one of channel encoding, rate matching, scrambling, constellation mapping, layer mapping, waveform modulation, antenna mapping, and / or resource mapping on the information bits. For example, when receiving data, the first device or the second device may perform at least one of signal extraction from resources, waveform demodulation for each antenna, signal arrangement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0052] For example, the layers of a radio interface protocol between a first device and a second device can be divided into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, a physical layer belonging to the first layer can provide an information transfer service using a physical channel, and an RRC (radio resource control) layer located in the third layer can play a role in controlling radio resources between the first device and the second device. For this purpose, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0053] FIG. 2 illustrates a radio protocol architecture according to an embodiment of the present disclosure. The embodiment of FIG. 2 can be combined with various embodiments of the present disclosure. For example, (a) of FIG. 2 may illustrate a radio protocol stack of a user plane for uplink communication or downlink communication, and (b) of FIG. 2 may illustrate a radio protocol stack of a control plane for uplink communication or downlink communication. For example, (c) of FIG. 2 may illustrate a radio protocol stack of a user plane for device-to-device communication, and (d) of FIG. 2 may illustrate a radio protocol stack of a control plane for device-to-device communication.

[0054] For example, the physical layer can provide information transmission services to upper layers using physical channels. For example, the physical layer can be connected to the upper layer, the medium access control (MAC) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through the transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted over the wireless interface. For example, data can be transmitted between different physical layers, for example, between the physical layers of a first device and a second device, through a physical channel. For example, the physical channel can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and time and frequency can be utilized as radio resources.

[0055] For example, the MAC layer can provide services to the upper layer, the radio link control (RLC) layer, through logical channels. For example, the MAC layer can provide a mapping function from multiple logical channels to multiple transport channels. For example, the MAC layer can provide a logical channel multiplexing function by mapping multiple logical channels to a single transport channel. For example, the MAC sublayer can provide data transmission services on logical channels.

[0056] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee the various quality of service (QoS) required by radio bearers (RBs), the RLC layer can provide three operating modes: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat request (ARQ).

[0057] For example, the RRC (radio resource control) layer can be defined only in the control plane. For example, the RRC layer can be responsible for controlling logical channels, transport channels, and physical channels in relation to the configuration, re-configuration, and release of radio bearers. For example, an RB can mean a logical path provided by a first layer (e.g., a physical layer) and a second layer (e.g., a MAC layer, an RLC layer, a PDCP (packet data convergence protocol) layer, a SDAP (service data adaptation protocol) layer, etc.) for data transmission between a first device and a second device.

[0058] For example, the functions of the PDCP layer in the user plane may include forwarding of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include forwarding of control plane data and ciphering / integrity protection.

[0059] For example, establishing an RB can refer to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. For example, RBs can be divided into two types: signaling radio bearers (SRBs) and data radio bearers (DRBs). For example, SRBs can be used as a channel to transmit RRC messages in the control plane, while DRBs can be used as a channel to transmit user data in the user plane.

[0060] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) for transmitting system information, and / or a downlink shared channel (SCH) for transmitting user traffic or control messages. For example, traffic or control messages of a downlink multicast or broadcast service may be transmitted through the downlink SCH, or may be transmitted through a separate downlink multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) for transmitting initial control messages, and / or an uplink shared channel (SCH) for transmitting user traffic or control messages. For example, a logical channel located above a transmission channel and mapped to the transmission channel may include at least one of a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and / or a multicast traffic channel (MTCH).

[0061] FIG. 3 illustrates the structure of a wireless frame according to an embodiment of the present disclosure. The embodiment of FIG. 3 can be combined with various embodiments of the present disclosure.

[0062] Referring to FIG. 3, for example, a radio frame may be used in uplink transmission, downlink transmission, and / or device-to-device transmission. For example, a radio frame may have a length of 10 ms and may be defined as two 5 ms half-frames (HF). For example, a half-frame may include five 1 ms subframes (SF). For example, a subframe may be divided into one or more slots, and the number of slots within a subframe may be determined according to a subcarrier spacing (SCS). For example, each slot may include 12 or 14 OFDM (A) symbols, depending on a cyclic prefix (CP).

[0063] For example, when normal CP is used, each slot can contain 14 symbols. For example, when extended CP is used, each slot can contain 12 symbols. Here, for example, the symbols can contain OFDM symbols (or CP-OFDM symbols), SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0064] Table 2 below shows the number of symbols per slot (N) depending on the SCS setting (u) when normal CP or extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot ) is an example.

[0065] CP type SCS (15*2u )N slot symb N frame,u slot N subframe,u slot Normal CP15kHz (u=0)1410130kHz (u=1)1420260kHz (u=2)14404120kHz (u=3)14808240kHz (u=4)1416016Extended CP60kHz (u=2)12404

[0066] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single terminal. Accordingly, the (absolute time) interval of time resources (e.g., subframes, slots, or transmit time intervals (TTIs)) composed of the same number of symbols may be set differently between the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTIs, etc. may be referred to as time units.

[0067] For example, multiple numerologies, or SCSs, may be supported to support various services. For example, a 15 kHz SCS may support wide areas in traditional cellular bands, while a 30 kHz / 60 kHz SCS may support dense urban areas, lower latency, and wider carrier bandwidth. For example, a 60 kHz or higher SCS may support bandwidths greater than 24.25 GHz to overcome phase noise.

[0068] FIG. 4 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 4 can be combined with various embodiments of the present disclosure.

[0069] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain, and may correspond to one numerology (e.g., SCS, CP length, etc.). For example, a carrier may include at most N BWPs (where N is a positive integer). For example, data communication may be performed through an activated BWP. For example, each element may be referred to as a resource element (RE) in the resource grid, and one complex symbol may be mapped to it.

[0070] For example, a BWP may be a contiguous set of PRBs in a given numerology. For example, a PRB may be selected from a contiguous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0071] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the UE may not monitor the downlink radio link quality in a DL BWP other than the active DL BWP on the PCell (primary cell). For example, the UE may not receive a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), or a channel state information-reference signal (CSI-RS) (except for radio resource management (RRM)) outside of the active DL BWP. For example, the UE may not trigger channel state information (CSI) reporting for an inactive DL BWP. For example, the UE may not transmit a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) outside of the active UL BWP. For example, for downlink, the initial BWP can be given as a set of consecutive resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For uplink, for example, the initial BWP can be given by the system information block (SIB) for the random access procedure. For example, the default BWP can be set by a higher layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if a terminal does not detect DCI (downlink control information) for a certain period of time, the terminal may switch its active BWP to a default BWP.

[0072] FIG. 5 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 5 can be combined with various embodiments of the present disclosure. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0073] Referring to FIG. 5, for example, a common resource block (CRB) may be a carrier resource block numbered from one end of a carrier band to the other, and a PRB may be a numbered resource block within each BWP. For example, point A may indicate a common reference point for a resource block grid.

[0074] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP ) can be set by. For example, point A can be an outer reference point of the PRB of a carrier where subcarrier 0 of all numerologies (e.g., all numerologies supported by the network on that carrier) aligns. For example, the offset can be the PRB spacing between the lowest subcarrier in a given numerology and point A. For example, the bandwidth can be the number of PRBs in a given numerology.

[0075] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to an embodiment of the present disclosure. The embodiment of FIG. 6 can be combined with various embodiments of the present disclosure.

[0076] As core implementation technologies of the 6G system, technologies such as artificial intelligence (AI), THz (terahertz) communication, optical wireless technology, free-space optical transmission (FSO) backhaul networks, massive MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0077] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. For example, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a crucial role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. AI can also facilitate rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0078] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by using sub-THz communication with wide bandwidths and applying advanced massive MIMO technology. THz waves, also known as sub-millimeter waves, typically refer to the frequency range between 0.1 THz and 10 THz, with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz to 300 GHz band (sub-THz band) is considered a key part of the THz spectrum for cellular communications. Adding the sub-THz band to the mmWave band will increase the capacity of 6G cellular communications. Among the defined THz bands, 300 GHz to 3 THz lies in the far infrared (IR) frequency band. While part of the optical band, the 300 GHz to 3 THz band lies at the boundary of the optical band, immediately following the RF band. Therefore, this 300 GHz to 3 THz band exhibits similarities to RF. Key characteristics of THz communications include (i) the widely available bandwidth to support very high data rates and (ii) the high path loss that occurs at high frequencies (requiring highly directional antennas). The narrow beamwidths generated by highly directional antennas reduce interference. The small wavelength of THz signals allows for a significantly larger number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array technologies to overcome range limitations.

[0092] Advanced Air Mobility (AAM): AAM can be a broad concept encompassing urban air mobility (UAM), regional air mobility (RAM), and uncrewed aerial systems (UAS). For example, AAM can include UAM, RAM, UAS, and uncrewed aerial vehicles (UAVs).

[0093] - Autonomous driving (self-driving): V2X (vehicle to everything), a key element in building autonomous driving infrastructure, can be a technology that allows cars to communicate and share with various elements on the road for autonomous driving, such as vehicle to vehicle (V2V) wireless communication and vehicle to infrastructure (V2I) wireless communication.

[0094] Non-terrestrial network (NTN): NTN can refer to a network or network segment that utilizes radio frequency (RF) resources mounted on satellites (or UAS platforms). NTN services may be considered to secure wider coverage or provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0095] - Integrated sensing and communication (ISAC): Wireless sensing is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the characteristics of the environment and / or objects within the environment.

[0096] - Reconfigurable intelligent surface (RIS): RIS can be used to manipulate and enhance signal propagation in wireless communication environments. For example, a RIS can be composed of many small antennas, or metasurfaces, arranged on a surface, each of which can actively control the phase, amplitude, polarization, etc. of the reflected signal. For example, a RIS can improve signal reception by controlling the path, phase, and / or intensity of the propagating signal. For example, in the case of a RIS, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For example, because a RIS can be reconfigured to suit different environments, it can meet diverse communication requirements and operate effectively in dynamic network environments.

[0097] FIG. 7 illustrates an example of a communication scenario based on a 6G system, according to an embodiment of the present disclosure. The embodiment of FIG. 7 may be combined with various embodiments of the present disclosure.

[0098] Referring to FIG. 7, NTN communication can be performed based on satellite networks, high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS), and terminals capable of aerial communication (e.g., AAMs). For example, to improve coverage, etc., devices such as satellite networks, HIBS, and terminals capable of aerial communication (e.g., AAMs) can act as relays. For example, an AAM can communicate with a base station, a satellite network, etc., and / or an AAM can communicate directly with a terminal, another AAM, etc.

[0099] FIG. 8 illustrates a procedure for uplink transmission and reception according to an embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure.

[0100] Referring to FIG. 8, for example, in step S801, the base station may schedule uplink transmissions such as frequency / time resources, transmission layers, uplink precoder, MCS, etc. For example, the base station may determine a beam for PUSCH transmission of the terminal through the operations described above.

[0101] For example, in step S802, the terminal may receive DCI for uplink scheduling (e.g., including scheduling information of PUSCH) from the base station on the PDCCH.

[0102] For example, DCI format 0_0 or 0_1 may be used for uplink scheduling, and in particular, DCI format 0_1 ​​may include the following information: Identifier for DCI formats, UL / SUL (Supplementary uplink) indicator, UL / SUL indicator, Bandwidth part indicator, Frequency domain resource assignment, Time domain resource assignment, Frequency hopping flag, Modulation and coding scheme (MCS), SRS resource indicator (SRI), Precoding information and number of layers, Antenna port(s), SRS request, DMRS sequence initialization, UL-SCH (Uplink Shared Channel) indicator

[0103] For example, SRS resources configured within a set of SRS resources associated with the upper layer parameter 'usage' can be indicated by the SRS resource indicator field. For example, 'spatialRelationInfo' can be configured for each SRS resource, and its value can be one of {CRI, SSB, SRI}.

[0104] For example, in step S803, the terminal may transmit uplink data to the base station on PUSCH.

[0105] For example, if a terminal detects a PDCCH including DCI format 0_0 or 0_1, it can transmit the corresponding PUSCH according to the instructions of the corresponding DCI.

[0106] For example, two transmission schemes (e.g., codebook-based transmission for PUSCH transmission and non-codebook-based transmission for PUSCH transmission) may be supported:

[0107] i) For example, when the upper layer parameter 'txConfig' is set to 'codebook', the terminal may be configured for codebook-based transmission. For example, when the upper layer parameter 'txConfig' is set to 'nonCodebook', the terminal may be configured for non-codebook-based transmission. For example, if the upper layer parameter 'txConfig' is not set, the terminal may not expect to be scheduled by DCI format 0_1. For example, when PUSCH is scheduled by DCI format 0_0, PUSCH transmission may be based on a single antenna port.

[0108] For example, in case of codebook-based transmission, PUSCH can be scheduled in DCI format 0_0, DCI format 0_1, or semi-statically. For example, if this PUSCH is scheduled by DCI format 0_1, the UE can determine the PUSCH transmission precoder based on the SRI, the transmit precoding matrix indicator (TPMI), and the transmission rank from the DCI, as given by the SRS resource indicator field and the precoding information and number of layers field. For example, the TPMI is used to indicate the precoder to be applied across antenna ports, and may correspond to the SRS resource selected by the SRI when multiple SRS resources are configured. For example, if a single SRS resource is configured, the TPMI is used to indicate the precoder to be applied across antenna ports, and may correspond to the single SRS resource. For example, a transmit precoder may be selected from an uplink codebook having the same number of antenna ports as the upper layer parameter 'nrofSRS-Ports'. For example, when a terminal sets an upper layer with 'codebook' as the parameter 'txConfig', the terminal may be configured with at least one SRS resource. For example, an SRI indicated in slot n is associated with the most recent transmission of the SRS resource identified by the SRI, wherein the SRS resource may precede the PDCCH carrying the SRI (e.g., slot n).

[0109] ii) For example, in case of non-codebook based transmission, PUSCH can be scheduled in DCI format 0_0, DCI format 0_1, or semi-statically. For example, when multiple SRS resources are configured, the UE can determine the PUSCH precoder and transmission rank based on the wideband SRI, where the SRI can be given by the SRS resource indicator in the DCI or by the higher layer parameter 'srs-ResourceIndicator'. For example, the UE uses one or multiple SRS resources for SRS transmission, where the number of SRS resources can be configured for simultaneous transmission within the same RB based on the UE capability. For example, only one SRS port can be configured for each SRS resource. For example, only one SRS resource can be configured with the higher layer parameter 'usage' set to 'nonCodebook'. For example, the maximum number of SRS resources that can be configured for non-codebook based uplink transmission may be 4. For example, the SRI indicated in slot n is associated with the most recent transmission of the SRS resource identified by the SRI, where the SRS transmission may precede the PDCCH carrying the SRI (e.g., slot n).

[0110] For example, an orthogonal cover code (OCC) may be initiated across PUSCH repetition(s).

[0111] For example, for OCC across PUSCH repetition(s), the following two directions can be considered:

[0112] - For example, Option 1: OCC with PUSCH repetition type A

[0113] - For example, Option 2: OCC with PUSCH repetition type B

[0114] For example, OCC across PUSCH repetitions could be a unified solution applicable to both IoT NTNs and NR NTNs, and could be a research direction to reduce standardization efforts. For example, the feasibility of applying OCC in GSO / NGSO environments should be reviewed, taking into account impairments such as time / frequency shifts and phase distortion.

[0115] FIG. 9 illustrates an example of an OCC with PUSCH repetition type A, according to an embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure.

[0116] Referring to Figure 9, for example, OCC with PUSCH repetition type A (Option 1) may be a method of applying OCC between PUSCH repetition(s) in which the PUSCH is repeated on a slot-by-slot basis. For example, a PUSCH assigned to a single slot may be repeatedly transmitted for multiple slots, and OCC may be applied across the PUSCH repetition(s). For example, in order to apply OCC between slots, the feasibility of maintaining the orthogonality of the OCC may need to be considered. For example, during the period in which OCC is applied, the gNB may expect the UE to maintain phase continuity and / or power consistency of PUSCH transmissions. For example, this may be supported by reusing the capabilities of DM-RS bundling introduced for UL coverage enhancement (e.g., nominal / actual TDW) or by defining new UE capabilities. For example, in NR-NTN, UEs may be expected to apply delay / Doppler pre-compensation during uplink transmissions, and the pre-compensation process may vary depending on the UE implementation. For example, to ensure OCC orthogonality, discussions regarding pre-compensation requirements for OCC may be necessary. For example, when an NTN UE reports OCC support capability, delay / Doppler pre-compensation capability within a certain level may be required as a prerequisite for OCC capability.

[0117] For example, for OCC with PUSCH repetition type A (option 1), OCC orthogonality may not be guaranteed without prerequisites such as phase continuity, power consistency, delay / Doppler pre-compensation, etc.

[0118] For example, for Option 1, some behaviors of PUSCH repetition type A may need to be changed. For example, in PUSCH repetition type A, when the PUSCH is repeated across slots, redundancy version (RV) cycling may be applied across the PUSCH repetition(s). For example, for Option 1, the same signal may need to be repeated to apply OCC, and thus the RV may need to be fixed between repeated transmissions. For example, if OCC across PUSCH repetition(s) also applies to the DM-RS sequence within the PUSCH, the DM-RS sequence may need to remain the same across PUSCH repetition(s). For example, according to the current specification, the PUSCH DM-RS sequence has an initial value that depends on the slot index, and when OCC is applied, the initial value for the PUSCH DM-RS sequence within a repeated transmission may be fixed to the same value.

[0119] For example, for OCC with PUSCH repetition type A (option 1), changes in RV and / or PUSCH DM-RS sequence across slots may not be suitable for OCC application.

[0120] For example, in Rel-17, support for PUSCH repetition type A for Msg3 PUSCH was also introduced. When discussing the application of OCC for PUSCH repetition type A, the application of OCC to Msg3 PUSCH may also be discussed. For example, for Msg3 PUSCH, uplink capacity / throughput may be reduced by up to 1 / 16 for a maximum repetition count of 16. For example, if OCC is not applied to Msg3 PUSCH, significant delay may occur during the initial access of an NTN UE. For example, for Msg3 PUSCH, OCC resources may be linked to RA preamble resources.

[0121] For example, for OCC with PUSCH repetition type A (option 1), this improvement can also be applied to Msg3 PUSCH with repetition(s).

[0122] For example, in Rel-19 NR NTN, OCC with PUSCH repetition type A can be studied by considering the following aspects:

[0123] - For example, phase continuity and / or power consistency

[0124] - For example, time / frequency shift pre-compensation

[0125] - For example, RV (redundancy version) cycling

[0126] - For example, DM-RS sequence initialization

[0127] - For example, Msg3 PUSCH enhancement

[0128] For example, in the communications field, the introduction of non-terrestrial networks (NTNs) that utilize satellites as network nodes is being actively discussed. For example, satellites that support NTNs can be classified according to their flight orbits and characteristics, such as GEO, MEO, and LEO, and generally have very high satellite altitudes. For example, the service area of ​​the satellite can have very wide coverage characteristics, and the number of target terminals within the service area can be relatively large. For example, the NTN service may require multiplexing support for multiple terminals. For example, since terrestrial terminals have transmission power constraints, coverage extension technologies can be applied to ensure that a sufficiently large signal reaches a high-altitude NTN during uplink transmission. For example, coverage extension can be achieved by having the terminal repeat the PUSCH (Physical Uplink Shared Channel), which is an uplink data channel, on the time axis. For example, the terminal may transmit the PUSCH using the DFT-s-OFDM (discrete Fourier transform spread orthogonal frequency division multiplexing) method for coverage gain. For example, the DFT-s-OFDM modulation method may refer to a modulation method in which DFT precoding (or DFT spreading) is applied as part of TF (transform) precoding before the OFDM modulation method. For example, the coverage extension technology may have reduced resource utilization efficiency due to repeated transmission, and an uplink multiplexing method using an orthogonal cover code (OCC) may be effective.For example, in the present disclosure below, when performing uplink repetitive transmission, a method for achieving capacity increase and / or multiplexing of an uplink data channel by utilizing OCC may be proposed.

[0129] For example, proposal #01 can be proposed.

[0130] For example, according to Proposal #01, when a terminal can apply OCC for an uplink data channel (e.g., PUSCH), a method may be proposed to determine the suitability of OCC setting / indication based on the interval between the repeated transmissions when applying OCC between repeated transmissions of the uplink data channel (e.g., PUSCH).

[0131] For example, the terminal may determine that the OCC setting / instruction is valid if the interval between repeated transmissions is less than a certain threshold value, and otherwise determine that the OCC setting / instruction is invalid. For example, if the terminal determines that the OCC setting / instruction is invalid, the terminal may perform one or more of the following actions.

[0132] For example, (1) OCC not applicable

[0133] For example, (2) (the) uplink data channel transmission omitted

[0134] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0135] For example, the above (explicit) repetition transmission (e.g., (nominal) repetition) means repetition transmission set / instructed by the base station, and the (explicit) repetition transmission may be divided into one or more (actual) repetition transmissions (e.g., (actual) repetitions) by invalid symbols and / or slot boundaries, etc.

[0136] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, a method may be considered in which the terminal repeatedly transmits the uplink data channel (time-axis) and applies an (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing one or more uplink data channel (e.g., PUSCH) transmissions (within the same cell). For example, if the interval between the repeated transmissions is excessively long, the terminal may not be able to maintain the phase continuity and / or power consistency characteristics of the signal, and in this case, even if an OCC is applied, data signals may not be canceled when the OCC is removed by a multiplication operation, which may cause interference effects. For example, the present disclosure may propose a method for determining the suitability of an OCC setting / indication based on the interval between repeated transmissions when applying an OCC between repeated transmissions of an uplink data channel (e.g., PUSCH). For example, the terminal may determine that the OCC setting / indication is valid if the interval between repeated transmissions is less than or equal to a certain reference value, and may determine that the OCC setting / indication is invalid otherwise. For example, if the OCC setting / indication is determined to be invalid, the terminal may not apply the OCC to the (corresponding) uplink data channel or may omit transmission of the (corresponding) uplink data channel. For example, according to the proposed method of the present disclosure, there may be an advantage in that the OCC can be effectively applied to an uplink data channel where the phase continuity and / or constant transmission power of the terminal transmission signal is guaranteed.

[0137] For example, the above proposed method #01 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0138] For example, proposal #02 can be proposed.

[0139] For example, according to Proposal #02, when a terminal can apply OCC for an uplink data channel (e.g., PUSCH), a method may be proposed in which a base station indicates to the terminal an OCC type and / or an OCC length and / or an OCC index for the uplink data channel in one of the following ways.

[0140] For example, (1) instructions based on dynamic control signals targeting a group of terminals (e.g., utilizing Group Common DCI).

[0141] For example, (2) MAC CE-based instructions

[0142] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0143] For example, the uplink data channel may be a CG (Configured Grant)-based uplink data channel. For example, the CG (Configured Grant)-based uplink data channel may refer to a method in which a base station allocates periodic uplink transmission resources to a terminal, and the terminal performs uplink transmission by utilizing some resources within the periodic uplink transmission resources. For example, type 1 CG may refer to a type in which scheduling is initiated through an RRC (Radio Resource Control) signal, and type 2 CG may refer to a type in which only resources are configured by RRC, but scheduling is initiated through DCI (Dynamic Control Information).

[0144] For example, the (indicated) OCC type and / or OCC length and / or OCC index may be applied after a certain period of time and / or after a specific timer expires after receiving the base station instruction.

[0145] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, it may be assumed that the terminal can apply OCC to the uplink data channel. For example, the base station may need to be able to provide the terminal with OCC information to be applied to the uplink data channel. For example, the OCC information to be applied to the uplink data channel may include an OCC type and / or an OCC length and / or an OCC index. For example, the OCC type may include a type in which OCC is applied within a symbol and / or a type in which OCC is applied between symbols (groups) and / or a type in which OCC is applied between slots (groups). For example, when the uplink data channel is a Configured Grant (CG)-based uplink data channel, the base station may reserve periodic uplink data channel transmission resources through a higher layer signal such as an RRC (Radio Resource Control), and the terminal may select whether to perform uplink transmission based on its buffer status for each periodic resource. For example, the base station can set OCC information for the CG-based uplink data channel through a higher layer signal such as RRC. For example, however, if the OCC information needs to be updated, the process of resetting the higher layer signal such as RRC may cause a large delay in the non-terrestrial network. For example, therefore, the present disclosure may propose a method in which the base station indicates to the terminal group-targeted dynamic control signal-based instructions (e.g., utilizing Group Common DCI) and / or MAC CE-based OCC information.For example, according to the proposed method of the present disclosure, there may be an advantage in that OCC information can be updated relatively quickly even for uplink data channels that do not have a unique dynamic control channel in the physical layer, such as a CG-based uplink data channel.

[0146] For example, the above proposed method #02 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0147] For example, proposal #03 can be proposed.

[0148] For example, according to Proposal #03, when a terminal can apply OCC for an uplink data channel (e.g., PUSCH), a method may be proposed in which a base station (pre-)configures and / or instructs the terminal to use OCC and / or uplink data channel transmission resources by RSRP (Reference Signal Received Power) and / or (DL) SINR (interval), and the terminal selects and transmits OCC and / or uplink data transmission resources according to (measured) RSRP and / or (DL) SINR.

[0149] For example, the above RSRP (Reference Signal Received Power) may mean reception strength and / or reception sensitivity for a (downlink) reference signal.

[0150] For example, the (downlink) reference signal for measuring the RSRP may be a (pre-)configured / instructed path loss measurement reference signal (e.g., Pathloss Reference Signal) for the uplink data channel.

[0151] For example, the OCC setting / instruction may include information such as OCC type / OCC length / OCC index.

[0152] For example, the uplink data channel may be a CG (Configured Grant)-based uplink data channel. For example, the CG (Configured Grant)-based uplink data channel may refer to a method in which a base station allocates periodic uplink transmission resources to a terminal, and the terminal performs uplink transmission by utilizing some resources within the periodic uplink transmission resources. For example, type 1 CG may refer to a type in which scheduling is initiated through an RRC (Radio Resource Control) signal, and type 2 CG may refer to a type in which only resources are configured by RRC, but scheduling is initiated through DCI (Dynamic Control Information).

[0153] For example, when the terminal can select and transmit OCC and / or uplink data transmission resources according to (measured) RSRP and / or (DL) SINR, the terminal can maintain the existing selected transmission resources for the currently ongoing (On-Going) transmission even if the RSRP and / or (DL) SINR measurement values ​​are updated.

[0154] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, it may be assumed that the terminal can apply OCC to the uplink data channel. For example, when multiple terminals transmit multiple uplink data channels to which OCC is applied, the orthogonality of the OCC may not be perfectly guaranteed due to the characteristics of the channel and RF. For example, the multiple uplink data channels may have some interference effects on each other since the orthogonality of the OCC is not guaranteed. For example, in order to prevent a case where a specific uplink data channel has a particularly strong signal strength and causes strong interference to other uplink data channels, it is desirable that the multiple uplink data channels multiplexed through the OCC have equivalent reception strength / sensitivity and / or reception SINR. For example, therefore, the present disclosure may propose a method in which, when a terminal can apply an OCC for an uplink data channel (e.g., PUSCH), a base station (in advance) configures and / or instructs the terminal to use OCC and / or uplink data channel transmission resources by RSRP (Reference Signal Received Power) and / or (DL) SINR (interval), and the terminal selects and transmits the OCC and / or uplink data transmission resources according to the (measured) RSRP and / or (DL) SINR. For example, according to the proposed method of the present disclosure, terminals with similar RSRP and / or (DL) SINR will attempt to multiplex an uplink data channel based on the OCC, and multiple uplink data channels may experience similar path attenuation and thus have similar reception strength / sensitivity and / or reception SINR. For example, therefore, a situation in which strong interference is caused to other uplink transmissions by a specific uplink transmission can be prevented in advance.

[0155] For example, the above proposed method #03 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0156] For example, proposal #04 can be proposed.

[0157] For example, according to Proposal #04, when a terminal can apply OCC for an uplink data channel (e.g., PUSCH), a method may be proposed in which the terminal performs one or more of the following operations when changing the initial value of sequence generation (in the time axis) for RS (Reference Signal) in the uplink data channel and / or Group Hopping and / or Sequence Hopping are applied.

[0158] For example, (1) Omitting (the) uplink data channel transmission;

[0159] For example, (2) OCC is not applied to the (corresponding) uplink data channel.

[0160] For example, (3) change of initial value of sequence generation (in time axis) for RS within (corresponding) uplink data channel and / or application of sequence group hopping and / or non-application of sequence hopping.

[0161] For example, (4) when changing the initial value of sequence generation (on the time axis) for RS in (the relevant) uplink data channel and / or applying sequence group hopping and / or sequence hopping, a method may be proposed to apply it based on the start (or last) slot and / or symbol within the OCC application period.

[0162] For example, the above RS may mean DM-RS (Demodulation Reference Signal).

[0163] For example, the above group hopping may mean a hopping operation for a group of sequences (indexes).

[0164] For example, the above sequence hopping may mean a hopping operation for a sequence (index) within a sequence group.

[0165] For example, the terminal may not expect that the application of OCC is set / instructed for the (corresponding) uplink data channel when a change in the initial value of sequence generation (on the time axis) and / or group hopping and / or sequence hopping is applied to the RS within the uplink data channel. For example, the terminal may not expect that the application of OCC is set / instructed for the uplink data channel when a change in the initial value of sequence generation (on the time axis) and / or group hopping and / or sequence hopping is applied to the RS within the uplink data channel.

[0166] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, it may be assumed that the terminal can apply OCC to the uplink data channel. For example, sequence generation initial value change (in the time axis) and / or group hopping and / or sequence hopping may be applied to RSs in the uplink data channel. For example, when applying OCC (in the time axis) to the uplink data channel, there may be cases where the sequence generation initial value change (in the time axis) and / or group hopping and / or sequence hopping operation and the (time axis) application unit are different. For example, OCC (in the time axis) may be applied between repeated transmissions of the uplink data channel and applied in units of multiple slots, and the (time axis) sequence generation initial value change and / or group hopping and / or sequence hopping operation may be applied in units of individual slots. For example, in the above case, the RS within the OCC application unit is changed, so the orthogonality of the OCC with respect to the RS is not maintained, which may cause interference.For example, therefore, in the case where a change in the initial value of sequence generation (in the time axis) and / or group hopping and / or sequence hopping is applied to an RS (Reference Signal) in an uplink data channel, a method may be proposed in which a terminal skips transmission of the uplink data channel or does not expect application of OCC to the uplink data channel or does not apply a change in the initial value of sequence generation (in the time axis) and / or sequence group hopping and / or sequence hopping operation to the RS in the uplink data channel or when applying a change in the initial value of sequence generation (in the time axis) and / or sequence group hopping and / or sequence hopping to the RS in the uplink data channel, the change is applied based on the start (or last) slot and / or symbol within the OCC application period. For example, in accordance with the proposed method of the present disclosure, when a change in the initial value of sequence generation (on the time axis) for an RS (Reference Signal) in an uplink data channel and / or group hopping and / or sequence hopping are applied, there may be an advantage in that the terminal operation related to the application of OCC to the uplink data channel can be clarified.

[0167] For example, the above proposed method #04 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0168] For example, proposal #05 can be proposed.

[0169] For example, according to Proposal #05, when a terminal can apply an OCC for an uplink data channel (e.g., PUSCH), a method may be proposed to support RS multiplexing between uplink data channels having different OCCs by linking an antenna port (identifier) ​​and an OCC (identifier) ​​for an RS (Reference Signal) within the uplink data channel and utilizing resources distinguished between the antenna ports (identifiers) in an FDM and / or TDM and / or CDM manner.

[0170] For example, the base station may indicate the (linked) OCC by indicating the antenna port to the terminal, or may indicate the (linked) antenna port by indicating the OCC.

[0171] For example, if the terminal is configured / instructed to apply OCC to the uplink data channel, it can be assumed that (MU-) MIMO operation is not applied.

[0172] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, it may be assumed that the terminal can apply an OCC to the uplink data channel. For example, when multiplexing uplink data channels based on an OCC, multiplexing for RSs in the uplink data channel may be supported by utilizing multiplexing resources that are defined separately from the OCC. For example, when resources for each antenna port for RSs in an uplink data channel are distinguished by FDM and / or CDM and / or TDM methods, the antenna port may be associated with a specific OCC (identifier), and RSs may be transmitted using the resources of the antenna port associated with the corresponding OCC. For example, according to the proposed method of the present disclosure, in order to support functions such as MU-MIMO (Multi-user Multiple Input Multiple Output), orthogonal RS resources provided for each antenna port can be utilized in conjunction with OCC resources, and existing multiplexing resources for RS can be efficiently utilized when multiplexing based on OCC for uplink data channels.

[0173] For example, the above proposed method #05 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0174] For example, proposal #06 can be proposed.

[0175] For example, according to Proposal #06, when a terminal can apply OCC for an uplink data channel (e.g., PUSCH), and when Channel State Information (CSI) is multiplexed in a UCI piggyback manner on the PUSCH to which the OCC is applied, a method may be proposed in which the terminal determines a slot / location of a (downlink) CSI reference resource for the CSI in one or more of the following ways.

[0176] For example, (1) based on the slot / location of PUCCH for CSI reporting

[0177] For example, in A. (1), when a PUCCH for CSI reporting is transmitted in multiple slots, a (downlink) CSI reference resource for the CSI can be determined based on the start and / or last slot / position of the corresponding resource group.

[0178] For example, (2) Decision based on the start or last slot / position of the resource group to which OCC is applied

[0179] For example, the above CSI reference resource may mean a downlink transmission resource / slot / location, etc. that the terminal references for CSI reporting.

[0180] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, a method may be considered in which the terminal repeatedly transmits the uplink data channel (time-wise) and applies an (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmission of one or more uplink data channels (e.g., PUSCH) (within the same cell).

[0181] For example, when a terminal needs to transmit an uplink control channel (e.g., PUCCH) that conflicts with the PUSCH repetitive transmission to which the OCC is applied, the terminal may transmit UCI (UL control information), which is control information to be transmitted on the PUCCH, by including it in the PUSCH channel (e.g., UCI piggyback). For example, if some of the repetitive transmissions of the PUSCH repetitive transmissions to which the OCC is applied are transmitted with UCI included, the OCC orthogonality may not be guaranteed because the data repetitive transmission is not maintained. For example, in the above case, the UCI may also be repetitively transmitted for the OCC applied resource group. For example, when the UCI is CSI, the CSI may be transmitted across multiple PUSCH transmission slots. For example, when the CSI is (periodic) PUCCH (hereinafter, referred to as the first PUCCH)-based CSI, the location of a downlink CSI reference resource (CSI reference resource) for CSI calculation may be determined based on the uplink slot in which the corresponding CSI report is transmitted. For example, if the CSI is extended within an OCC group, the definition of an uplink slot may become ambiguous. For example, therefore, in the present disclosure, when a terminal can apply an OCC to an uplink data channel (e.g., a PUSCH), and channel state information (CSI) is multiplexed in a UCI piggyback manner on the PUSCH to which the OCC is applied, a method may be proposed in which the terminal determines the slot / location of a (downlink) CSI reference resource for the CSI in one or more of the following ways.

[0182] For example, (1) based on the slot / location of PUCCH for CSI reporting

[0183] For example, in A. (1), when a PUCCH for CSI reporting is transmitted in multiple slots, a (downlink) CSI reference resource for the CSI can be determined based on the start and / or last slot / position of the corresponding resource group.

[0184] For example, (2) Decision based on the start or last slot / position of the resource group to which OCC is applied

[0185] For example, according to the proposed method of the present disclosure, when (periodic) CSI is multiplexed within a PUSCH to which OCC is applied and CSI information is extended and transmitted over multiple uplink slots, there may be an advantage in that the determination of CSI reference resources can be made clearly.

[0186] For example, the above proposed method #06 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0187] For example, proposal #07 can be proposed.

[0188] For example, according to the proposal #07, when a base station (or network) and / or a terminal supports application of OCC to an uplink data channel (e.g., PUSCH), a method may be proposed in which the base station (or network node) (in advance) defines and / or sets and / or instructs the terminal to perform UCI piggyback and / or transmit UCI in PUSCH a Beta-offset parameter (which controls a UCI coding rate) and / or an Alpha parameter (which controls a maximum number of REs for UCI transmission) and / or a maximum number of REs for UCI transmission, depending on whether OCC is applied and / or on an OCC scheme and / or parameter / condition.

[0189] For example, the OCC scheme and / or parameters / conditions may be distinguished according to one or more of the following:

[0190] For example, (1) whether OCC applies

[0191] For example, (2) OCC type

[0192] For example, there may exist an OCC type (hereinafter, the first OCC type) in which OCC is applied between (time axis) slots and / or PUSCH (repetitive) transmission units, and an OCC type (hereinafter, the second OCC type) in which OCC is applied between (virtual) frequency axis resources (before DFT spreading).

[0193] For example, (3) OCC length

[0194] For example, A. OCC length can be 2 or 4.

[0195] For example, (4) whether TBoMS (TB over Multiple Slot) is applied

[0196] For example, (5) the number of PUCCH and / or PUCCH repetition transmissions;

[0197] For example, (6) the number of UCI and / or PUCCH target UCI piggyback

[0198] For example, the above OCC scheme may include cases where OCC is not applied.

[0199] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, a method may be considered in which the terminal repeatedly transmits the uplink data channel (time-wise) and applies an (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmission of one or more uplink data channels (e.g., PUSCH) (within the same cell).

[0200] For example, when a terminal needs to transmit an uplink control channel (e.g., PUCCH) that conflicts with the PUSCH repetitive transmission to which the OCC is applied, the terminal may transmit UCI (UL control information), which is control information to be transmitted on the PUCCH, by including it in the PUSCH channel (e.g., UCI piggyback). For example, if some of the repetitive transmissions of the PUSCH repetitive transmissions to which the OCC is applied are transmitted with UCI included, the OCC orthogonality may not be guaranteed because the data repetitive transmission is not maintained. For example, therefore, in the above case, the UCI may also be repetitively transmitted for the OCC applied resource group. For example, if the UCI is repetitively transmitted for the OCC applied resource group, the signaling overhead required for UCI transmission may increase compared to the conventional case, and in such a case, the code rate for the UCI may need to be adjusted. For example, therefore, the present disclosure may propose a method in which, when a base station (or a network) and / or a terminal supports application of OCC to an uplink data channel (e.g., PUSCH), the base station (or a network node) may (pre-)define and / or set and / or indicate, for example, whether to apply OCC and / or according to an OCC scheme and / or parameters / conditions, a Beta-offset parameter (which controls a UCI coding rate) and / or an Alpha parameter (which controls a maximum number of REs for UCI transmission) and / or a maximum number of REs for UCI transmission when performing UCI piggyback and / or transmitting UCI within a PUSCH. For example, the OCC scheme and / or parameters / conditions may be distinguished according to one or more of the following items.

[0201] For example, (1) whether OCC applies

[0202] For example, (2) OCC type

[0203] For example, there may exist an OCC type (hereinafter, the first OCC type) in which OCC is applied between (time axis) slots and / or PUSCH (repetitive) transmission units, and an OCC type (hereinafter, the second OCC type) in which OCC is applied between (virtual) frequency axis resources (before DFT spreading).

[0204] For example, (3) OCC length

[0205] For example, A. OCC length can be 2 or 4.

[0206] For example, (4) whether TBoMS (TB over Multiple Slot) is applied

[0207] For example, (5) the number of PUCCH and / or PUCCH repetition transmissions;

[0208] For example, (6) the number of UCI and / or PUCCH target UCI piggyback

[0209] For example, the beta offset value for adjusting the encoding rate of UCI may be set differently when OCC is not applied and when OCC is applied, and the beta offset value may also be set differentially depending on the applied OCC length, OCC type, etc.

[0210] For example, when OCC is applied, the maximum number of UCI REs that can be allocated in a PUSCH can be scaled down by the OCC length compared to when OCC is not applied. For example, when performing UCI piggyback in a PUSCH with OCC applied, if the code rate of data and / or UCI falls below a certain threshold (set / indicated in advance), the UCI piggyback may not be performed and the (overlapping) PUSCH transmission may be omitted and PUCCH transmission may be performed, or the (overlapping) PUCCH transmission may be omitted and PUSCH transmission may be performed. For example, if the code rate of the data and / or UCI does not fall below a certain threshold (set / indicated in advance), the UE may perform UCI piggyback.

[0211] For example, if the proposed method of the present disclosure is followed, when UCI in a PUSCH to which OCC is applied is repeatedly transmitted for the purpose of maintaining the orthogonal characteristics of the OCC, there may be an effect of supporting a base station (or network node) to control the signal transmission load due to the repeated transmission of the UCI.

[0212] For example, the above proposed method #07 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0213] FIG. 10 illustrates an example of multiplexing for UCI according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure.

[0214] Referring to FIG. 10, for example, PUSCH repetition may be performed. For example, the PUSCH repetition may be PUSCH repetition type A. For example, PUSCH repetition type A may be a case where the PUSCH is repeated over slots. For example, an OCC may be applied to the PUSCH repetition. For example, the OCC applied to the PUSCH repetition may be an OCC with PUSCH repetition type A (option 1). For example, the OCC with PUSCH repetition type A (option 1) may be a method of applying an OCC between PUSCH repetition(s) in which the PUSCH is repeated on a slot-by-slot basis.

[0215] For example, the OCC length may be 4. For example, unlike as illustrated in FIG. 10, the OCC length may not be limited to 4. For example, the OCC length may be 2. For example, there may be OCC groups to which OCCs are applied based on the OCC length. For example, there may be a first OCC group and a second OCC group. For example, unlike as illustrated in FIG. 10, the number of OCC groups may not be limited to 2.

[0216] For example, UCI can be multiplexed on PUSCH repetitions. For example, UCI can be multiplexed on all PUSCH repetitions within an OCC group where inter-slot OCC is applied. For example, UCI can be multiplexed on all PUSCH repetitions within the first OCC group. For example, based on the overlap between UCI and PUSCH repetitions within the first OCC group, UCI can be multiplexed on all PUSCH repetitions within the first OCC group.

[0217] For example, when UCI multiplexing is performed for uplink channel repetitions to which OCC is applied, there may be a problem of increased overhead because UCI multiplexing must be performed for all uplink channel repetitions within the OCC group to ensure orthogonality within the OCC group.

[0218] For example, proposal #08 can be proposed.

[0219] FIG. 11 illustrates an example of transmitting UCI on a PUSCH based on a beta offset, according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure.

[0220] Referring to FIG. 11, for example, in step S1110, the base station may transmit information related to one or more beta offsets to the device. For example, one or more beta offsets may be defined to determine the number of resources for the UE to multiplex HARQ-ACK information on the PUSCH and to multiplex CSI reports. For example, one or more beta offsets may also be defined to multiplex CG-UCI or UTO-UCI. For example, the offset value may be signaled to the UE by a DCI format that schedules PUSCH transmissions or by a higher layer.

[0221] For example, in step S1120, the device may apply an OCC to a PUSCH repetition. For example, the PUSCH repetition may be PUSCH repetition type A. For example, PUSCH repetition type A may be a case where the PUSCH is repeated over slots. For example, an OCC may be applied to the PUSCH repetition. For example, the OCC applied to the PUSCH repetition may be an OCC with PUSCH repetition type A (option 1). For example, the OCC with PUSCH repetition type A (option 1) may be a method of applying an OCC between PUSCH repetition(s) in which the PUSCH is repeated on a slot-by-slot basis.

[0222] For example, in step S1130, the device may multiplex UCI on PUSCH repetitions. For example, the device may multiplex UCI on one or more PUSCH repetitions among the PUSCH repetitions. For example, the device may multiplex UCI on all PUSCH repetitions within an OCC group to which the OCC including the one or more PUSCH repetitions applies.

[0223] For example, in step S1140, the device may perform PUSCH repetition based on a beta offset for transmission of the UCI. For example, the beta offset for transmission of the UCI may be a beta offset among one or more beta offsets. For example, the beta offset for transmission of the UCI may be based on the OCC being applied between the PUSCH repetitions and the UCI being multiplexed in one or more PUSCH repetitions among the PUSCH repetitions. For example, the PUSCH repetition performed based on the beta offset for transmission of the UCI may be one or more PUSCH repetitions among the PUSCH repetitions.

[0224] For example, according to Proposal #08, when a base station (or network) and / or a terminal supports OCC application for an uplink data channel (e.g., PUSCH), when a PUCCH transmission collides with one or more PUSCH resource group(s) (to which OCC is applied), a scheme may be proposed in which the terminal selects a PUSCH resource group(s) (to which OCC is applied) that satisfies one or more of the following conditions, and transmits UCI to the corresponding resource group(s) (e.g., UCI piggyback).

[0225] For example, (1) satisfying the processing time and / or timeline conditions for UCI transmission;

[0226] For example, (2) the fastest resource group on the time axis

[0227] For example, (3) a resource group that has at least one resource that overlaps with PUCCH on the time axis.

[0228] For example, (4) a resource group whose OCC length and / or number of resources is greater than or equal to the first criterion.

[0229] For example, the PUCCH transmission may be transmitted in multiple resources and / or slots.

[0230] For example, the resource group may consist of multiple PUSCH transmission slot(s).

[0231] For example, the PUSCH resource group to which the OCC is applied may be composed of resources to which a specific single OCC code is applied.

[0232] For example, the above UCI piggyback may mean a method of allocating and / or transmitting UCI (UL Control Information) within PUCCH within PUSCH transmission resources.

[0233] For example, the first criterion may be (pre-)defined and / or set and / or indicated by the base station (or network node). For example, the first criterion may be a PUCCH (repetition) transmission length.

[0234] For example, the base station (or network node) may (pre-)define and / or set and / or instruct which of the above conditions to consider, or the terminal may select valid conditions according to a pre-arranged manner.

[0235] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, a method may be considered in which the terminal repeatedly transmits the uplink data channel (time-wise) and applies an (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmission of one or more uplink data channels (e.g., PUSCH) (within the same cell).

[0236] For example, when a terminal needs to transmit an uplink control channel (e.g., PUCCH) that collides with the PUSCH repetitive transmission to which the OCC is applied, the terminal may transmit UCI (UL control information), which is control information to be transmitted on the PUCCH, by including it in the PUSCH channel (e.g., UCI piggyback). For example, if some of the repetitive transmissions of the PUSCH repetitive transmissions to which the OCC is applied are transmitted with UCI included, the OCC orthogonality may not be guaranteed because the data repetitive transmission is not maintained. For example, therefore, in the above case, the UCI may also be repetitively transmitted for the resource group to which the OCC is applied. For example, if the PUCCH transmission is also repetitively transmitted across multiple slots, the PUCCH transmission may collide with one or more OCC resource group(s). For example, the terminal operation may need to determine which of the OCC resource group(s) to which the UCI should be transmitted. For example, therefore, in the present disclosure, when a base station (or network) and / or a terminal supports application of OCC to an uplink data channel (e.g., PUSCH), when a PUCCH transmission collides with one or more PUSCH resource group(s) (to which OCC is applied), a method may be proposed in which the terminal selects a PUSCH resource group(s) (to which OCC is applied) that satisfies one or more of the following conditions, and transmits UCI to the corresponding resource group(s) (e.g., UCI piggyback).

[0237] For example, (1) satisfying the processing time and / or timeline conditions for UCI transmission;

[0238] For example, (2) the fastest resource group on the time axis

[0239] For example, (3) a resource group that has at least one resource that overlaps with PUCCH on the time axis.

[0240] For example, (4) a resource group whose OCC length and / or number of resources is greater than or equal to the first criterion.

[0241] For example, when a PUCCH transmission collides with one or more PUSCH resource group(s) (to which OCC is applied), the terminal may perform UCI piggyback within the resource group that satisfies the computation time and / or timeline conditions for UCI transmission among the PUSCH resource group(s) (to which OCC is applied) and is earliest in the time axis. For example, when a PUCCH transmission collides with one or more PUSCH resource group(s) (to which OCC is applied), the terminal may sequentially select resource group(s) on the time axis that satisfies the computation time and / or timeline conditions for UCI transmission among the PUSCH resource group(s) (to which OCC is applied) and perform UCI piggyback. For example, when the terminal sequentially selects resource group(s) on which UCI piggyback is to be performed, the terminal may select the (total) PUSCH transmission resource amount to be a minimum value that is equal to or greater than the PUCCH transmission resource amount (or a maximum value that is equal to or less than the PUCCH transmission resource amount).

[0242] For example, if the proposed method of the present disclosure is followed, when PUCCH transmission collides with one or more OCC resource group(s), there may be an advantage of aligning understanding between the base station (or network node) and the terminal by clarifying the OCC resource group in which the terminal will transmit UCI, thereby supporting correct transmission and reception of UCI and / or data.

[0243] For example, by independently setting the beta offset depending on whether OCC is applied, the problem of increased overhead due to the need to perform UCI multiplexing for all uplink channel repetitions within an OCC group in order to ensure orthogonality within the OCC group when performing UCI multiplexing for uplink channel repetitions to which OCC is applied can be solved.

[0244] For example, the above proposed scheme #08 can be applied in combination with other proposed scheme(s) to the extent that the operations of the present disclosure do not conflict.

[0245] For example, proposal #09 can be proposed.

[0246] For example, according to Proposal #09, a terminal in a terrestrial and / or non-terrestrial network transmits a CFO (Carrier Frequency Offset) related report including one or more of the following signals and / or information to a base station (or network node) through an uplink channel (hereinafter referred to as the first channel),

[0247] For example, (1) instantaneous and / or average and / or maximum and / or minimum CFO (estimated at the terminal end);

[0248] For example, (2) CFO change rate (e.g., CFO drift rate) (estimated at the terminal end)

[0249] For example, (3) reference signal for CFO estimation (at the base station level)

[0250] For example, the base station (or network node) may be proposed to interpret and / or apply the CFO-related report based on one or more of the following points in time:

[0251] For example, (1) the reception time of the first channel

[0252] For example, (2) the time of transmission of the first channel (or the time of application of TA compared to the time of reception of the first channel)

[0253] For example, (3) the timing of satellite-related information transmission and / or update;

[0254] For example, the above CFO related report may be transmitted together with the TA (Timing Advanced) report or reported separately, depending on (pre) definition and / or configuration and / or instructions of the base station (or network node).

[0255] For example, the CFO related report may be triggered when the CFO (estimated at the terminal) exceeds and / or deviates from a certain reference value and / or range.

[0256] For example, the CFO-related report may be triggered when the terminal receives satellite-related information (e.g., ephemeris information) that is updated compared to the previous one.

[0257] For example, the satellite-related information may include ephemeris information of the satellite.

[0258] For example, in a next-generation mobile communication system according to an embodiment of the present disclosure, it may be assumed that a terminal transmits an uplink data channel (e.g., PUSCH). For example, a method may be considered in which the terminal repeatedly transmits the uplink data channel (time-wise) and applies an (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmission of one or more uplink data channels (e.g., PUSCH) (within the same cell).

[0259] For example, in a non-terrestrial network, a certain level of (residual) CFO (Carrier Frequency Offset) error may occur during uplink transmission due to the altitude and / or speed of the satellite. For example, when a plurality of PUSCHs with different OCCs are transmitted, the more the (residual) CFOs for each PUSCH are aligned, the more the orthogonality of the OCCs can be guaranteed. For example, if the base station (or network node) can predict (residual) CFO information for each terminal, it can support OCC-based multiplexed PUSCH transmission by grouping terminals with similar (residual) CFOs. For example, therefore, the present disclosure provides a method in which a terminal in a terrestrial and / or non-terrestrial network transmits a CFO (Carrier Frequency Offset)-related report including one or more of the following signals and / or information to a base station (or network node) through an uplink channel (hereinafter, a first channel),

[0260] For example, (1) instantaneous and / or average and / or maximum and / or minimum CFO (estimated at the terminal end);

[0261] For example, (2) CFO change rate (e.g., CFO drift rate) (estimated at the terminal end)

[0262] For example, (3) reference signal for CFO estimation (at the base station level)

[0263] For example, the base station (or network node) may be proposed to interpret and / or apply the CFO-related report based on one or more of the following points in time:

[0264] For example, (1) the reception time of the first channel

[0265] For example, (2) the time of transmission of the first channel (or the time of application of TA compared to the time of reception of the first channel)

[0266] For example, (3) the timing of satellite-related information transmission and / or update;

[0267] For example, if the proposed method of the present disclosure is followed, a base station (or network node) can predict (residual) CFO information for each terminal during uplink transmission, and thereby multiplex PUSCH resources between terminals with better OCC orthogonality guaranteed, thereby increasing the OCC-based channel capacity increase effect.

[0268] For example, the above proposed method #09 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0269] FIG. 12 illustrates a method for a device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.

[0270] Referring to FIG. 12, for example, in step S1210, the device may obtain information related to one or more beta offsets. For example, in step S1220, the device may obtain information related to an orthogonal cover code. For example, in step S1230, the device may perform uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, the beta offset for transmitting the uplink control information may be a beta offset related to the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0271] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, and based on the length of the orthogonal cover code.

[0272] For example, the length of the orthogonal cover code can be 2 or 4.

[0273] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, and based on the number of the uplink shared channel repetitions.

[0274] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information in the one or more uplink shared channel repetitions, and based on the number of the multiplexed uplink control information.

[0275] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, and based on transmission blocks on multiple slots.

[0276] For example, the device may obtain one or more alpha parameters. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the uplink control information in the one or more uplink shared channel repetitions, the alpha parameter for the transmission of the uplink control information may be an alpha parameter associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0277] For example, the number of resource elements that can be used for the transmission of the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions and on multiplexing the uplink control information in the one or more uplink shared channel repetitions.

[0278] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, the uplink control information may be multiplexed on all uplink shared channel repetitions within the orthogonal cover code group to which the orthogonal cover code is applied, including the one or more uplink shared channel repetitions.

[0279] For example, the device can obtain information related to the index of the antenna port for the reference signal. For example, the index related to the orthogonal cover code can be set based on the index of the antenna port.

[0280] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the channel state information in the one or more uplink shared channel repetitions, the location of the channel state information reference resource associated with the channel state information may be based on the first slot of the plurality of uplink control channels for reporting the channel state information.

[0281] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the channel state information in the one or more uplink shared channel repetitions, the location of the channel state information reference resource associated with the channel state information may be based on the last slot of the plurality of uplink control channels for reporting the channel state information.

[0282] For example, based on applying at least one of group hopping or sequence hopping to a reference signal in the uplink shared channel repetition, the orthogonal cover code may not be applied between the uplink shared channel repetitions.

[0283] For example, information related to the orthogonal cover code can be received from a base station.

[0284] For example, information related to the orthogonal cover code may be included in group common downlink control information received from the base station.

[0285] For example, the information related to the orthogonal cover code may include at least one of information related to the type of the orthogonal cover code, information related to the length of the orthogonal cover code, and information related to the index of the orthogonal cover code.

[0286] For example, the device may report information related to carrier frequency offset.

[0287] For example, the information related to the carrier frequency offset may include at least one of information related to a value of the carrier frequency offset, information related to a rate of change of the carrier frequency offset, or information related to a reference signal for estimating the carrier frequency offset.

[0288] For example, the value of the carrier frequency offset may include at least one of an instantaneous value of the carrier frequency offset, an average value of the carrier frequency offset, a maximum value of the carrier frequency offset, or a minimum value of the carrier frequency offset.

[0289] For example, reporting of information related to the carrier frequency offset may be triggered based on at least one of the value of the carrier frequency offset exceeding a threshold or acquiring satellite-related information.

[0290] The proposed method can be applied to devices according to various embodiments of the present disclosure. For example, first, the processor (102) of the device (100) can obtain information related to one or more beta offsets. For example, and then, the processor (102) of the device (100) can obtain information related to an orthogonal cover code. For example, and then, the processor (102) of the device (100) can perform uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, the beta offset for transmitting the uplink control information can be a beta offset related to the uplink, control information, and the orthogonal cover code among the one or more beta offsets.

For example, the instructions, when executed by the at least one processor, may cause the device to: obtain information associated with one or more beta offsets; obtain information associated with an orthogonal cover code; and perform uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, a beta offset for transmission of the uplink control information may be a beta offset associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0292] According to one embodiment of the present disclosure, a processing device configured to control a device may be provided. For example, the processing device may include at least one processor; and at least one memory coupled to the at least one processor and storing instructions. For example, the instructions, when executed by the at least one processor, may cause the device to: obtain information related to one or more beta offsets; obtain information related to an orthogonal cover code; and perform uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, a beta offset for transmission of the uplink control information may be a beta offset associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0293] According to one embodiment of the present disclosure, a non-transitory computer-readable storage medium having instructions recorded thereon may be provided. For example, the instructions, when executed, may cause a device to: obtain information associated with one or more beta offsets; obtain information associated with an orthogonal cover code; and perform uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, a beta offset for transmitting the uplink control information may be a beta offset associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0294] FIG. 13 illustrates a method for a base station to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 13 may be combined with various embodiments of the present disclosure.

[0295] Referring to FIG. 13, for example, in step S1310, the base station may transmit information related to one or more beta offsets. For example, in step S1320, the base station may transmit information related to an orthogonal cover code. For example, in step S1330, the base station may receive an uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, the beta offset for transmitting the uplink control information may be a beta offset related to the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0296] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, and based on the length of the orthogonal cover code.

[0297] For example, the length of the orthogonal cover code can be 2 or 4.

[0298] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, and based on the number of the uplink shared channel repetitions.

[0299] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information in the one or more uplink shared channel repetitions, and based on the number of the multiplexed uplink control information.

[0300] For example, the beta offset for transmitting the uplink control information may be based on applying the orthogonal cover code between the uplink shared channel repetitions, based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, and based on transmission blocks on multiple slots.

[0301] For example, the base station may transmit one or more alpha parameters. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, the alpha parameter for the transmission of the uplink control information may be an alpha parameter associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0302] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the uplink control information on the one or more uplink shared channel repetitions, the uplink control information may be multiplexed on all uplink shared channel repetitions within the orthogonal cover code group to which the orthogonal cover code is applied, including the one or more uplink shared channel repetitions.

[0303] For example, the base station may transmit information related to the index of the antenna port for the reference signal. For example, the index related to the orthogonal cover code may be set based on the index of the antenna port.

[0304] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the channel state information in the one or more uplink shared channel repetitions, the location of the channel state information reference resource associated with the channel state information may be based on the first slot of the plurality of uplink control channels for reporting the channel state information.

[0305] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the channel state information in the one or more uplink shared channel repetitions, the location of the channel state information reference resource associated with the channel state information may be based on the first slot of the plurality of uplink control channels for reporting the channel state information.

[0306] For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing the channel state information in the one or more uplink shared channel repetitions, the location of the channel state information reference resource associated with the channel state information may be based on the last slot of the plurality of uplink control channels for reporting the channel state information.

[0307] For example, based on applying at least one of group hopping or sequence hopping to a reference signal in the uplink shared channel repetition, the orthogonal cover code may not be applied between the uplink shared channel repetitions.

[0308] For example, information related to the orthogonal cover code can be received from a base station.

[0309] For example, information related to the orthogonal cover code may be included in group common downlink control information received from the base station.

[0310] For example, the information related to the orthogonal cover code may include at least one of information related to the type of the orthogonal cover code, information related to the length of the orthogonal cover code, and information related to the index of the orthogonal cover code.

[0311] For example, a base station may receive information related to carrier frequency offset.

[0312] For example, the information related to the carrier frequency offset may include at least one of information related to a value of the carrier frequency offset, information related to a rate of change of the carrier frequency offset, or information related to a reference signal for estimating the carrier frequency offset.

[0313] For example, the value of the carrier frequency offset may include at least one of an instantaneous value of the carrier frequency offset, an average value of the carrier frequency offset, a maximum value of the carrier frequency offset, or a minimum value of the carrier frequency offset.

[0314] For example, reporting of information related to the carrier frequency offset may be triggered based on at least one of the value of the carrier frequency offset exceeding a threshold or acquiring satellite-related information.

[0315] The proposed method can be applied to devices according to various embodiments of the present disclosure. For example, first, the processor (202) of the base station (200) can control the transceiver (206) to transmit information related to one or more beta offsets. For example, and the processor (202) of the base station (200) can control the transceiver (206) to transmit information related to an orthogonal cover code. For example, and the processor (202) of the base station (200) can control the transceiver (206) to receive an uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, the beta offset for transmitting the uplink control information can be a beta offset related to the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0316] According to one embodiment of the present disclosure, a base station may be provided. For example, the base station may include at least one transceiver; at least one processor; and at least one memory coupled to the at least one processor and storing instructions. For example, the instructions, based on execution by the at least one processor, may cause the base station to: transmit information associated with one or more beta offsets; transmit information associated with an orthogonal cover code; and receive an uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more of the uplink shared channel repetitions, a beta offset for transmitting the uplink control information may be a beta offset associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

For example, the instructions, based on execution by the at least one processor, may cause the base station to: transmit information associated with one or more beta offsets; transmit information associated with an orthogonal cover code; and receive an uplink shared channel repetition. For example, based on applying the orthogonal cover code between the uplink shared channel repetitions and based on multiplexing uplink control information in one or more uplink shared channel repetitions among the uplink shared channel repetitions, a beta offset for transmitting the uplink control information may be a beta offset associated with the uplink and control information and the orthogonal cover code among the one or more beta offsets.

[0318] According to one embodiment of the present disclosure, a non-transitory computer-readable storage medium having instructions recorded thereon may be provided. For example, the instructions, when executed, may cause a base station to: transmit information associated with one or more beta offsets; transmit information associated with an orthogonal cover code; and receive an uplink shared channel repetition.

[0339] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 16. Here, the codeword is an encoded bit sequence of an information block. The information block can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).

[0340] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010).

[0342] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 16. For example, a wireless device (e.g., 100, 200 of FIG. 15) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
