[0047] 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.

[0048] 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).

[0049] 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.

[0050] 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).

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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).

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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).

[0062] 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.

[0063] 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).

[0064] 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).

[0065] 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.

[0066] 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

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] For example, the BWP can be set by Point A, an offset from Point A (NstartBWP), and a bandwidth (NsizeBWP). For example, Point A can be an outer reference point of a 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.

[0076] 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.

[0077] 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.

[0078] - 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.

[0079] - 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.

[0093] 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).

[0094] - 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.

[0095] 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.

[0096] - 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.

[0097] - 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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: DCI format identifier, 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.

[0104] 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}.

[0105] For example, in step S803, the terminal may transmit uplink data to the base station on PUSCH.

[0106] 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.

[0107] For example, two transmission schemes (e.g., codebook-based transmission for PUSCH transmission and non-codebook-based transmission for PUSCH transmission) may be supported:

[0108] 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.

[0109] 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).

[0110] 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).

[0111] For example, an orthogonal cover code (OCC) may be initiated across PUSCH repetition(s).

[0112] For example, for OCC across PUSCH repetition(s), the following two directions can be considered:

[0113] - For example, Option 1: OCC with PUSCH repetition type A

[0114] - For example, Option 2: OCC with PUSCH repetition type B

[0115] 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.

[0116] 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.

[0117] 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 the OCC is applied, the gNB may expect the UE to maintain phase continuity and / or power consistency of the PUSCH transmission. 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] For example, in Rel-17, support for PUSCH repetition type A for Msg3 PUSCH was also introduced. When discussing the application of OCC to PUSCH Repetition Type A, the application of OCC to Msg3 PUSCH may also be considered within the scope of research. 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.

[0122] For example, for OCC with PUSCH repetition type A (option 1), this improvement can also be applied to Msg3 PUSCH with repetition(s).

[0123] For example, in Rel-19 NR NTN, OCC with PUSCH repetition type A can be studied by considering the following aspects:

[0124] - For example, phase continuity and / or power consistency

[0125] - For example, time / frequency shift pre-compensation

[0126] - For example, RV (redundancy version) cycling

[0127] - For example, DM-RS sequence initialization

[0128] - For example, Msg3 PUSCH enhancement

[0129] 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 discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) method for coverage gain. For example, the DFT-s-OFDM modulation method may refer to a modulation method in which DFT precoding (e.g., 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.

[0130] For example, proposal #01 can be proposed.

[0131] For example, according to Proposal Scheme #01, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) during transmission of an uplink data channel (e.g., PUSCH), a scheme may be proposed in which the terminal expects application of OCC within a time interval (pre-)promised and / or set / indicated between the base station and / or the terminal.

[0132] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0133] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0134] For example, the time interval may be a time interval in which phase continuity and / or power consistency and / or timing advance and / or channel are expected to be maintained (within a certain error range). For example, it may be related to a time interval in which bundling operation is possible for a DM-RS (Demodulation Reference Signal).

[0135] For example, the terminal may report terminal capabilities related to the time interval. For example, the terminal may report the (maximum) time interval during which it can maintain phase continuity and / or power consistency as capability information.

[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-wise) and applies a (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). For example, in order for the (time-axis) OCC to be effective, the phase continuity and / or power consistency and / or timing advance and / or channel of a signal transmitted by the terminal may need to remain substantially unchanged during the time during which the OCC is applied. For example, the present disclosure may propose a scheme in which, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in terms of time axis) when transmitting an uplink data channel, a scheme in which the terminal expects OCC application within a time interval (preliminarily) agreed upon and / or set / indicated between a base station and / or the terminal. For example, the time interval may be a time interval in which phase continuity and / or power consistency and / or timing advance and / or channel, etc., are expected to be maintained (within a certain error range). For example, if OCC application exceeding the time interval is instructed, the terminal may ignore the OCC application. For example, according to the proposed scheme of the present disclosure, unnecessary complexity can be reduced by performing OCC application only when the terminal is valid.

[0137] For example, the above proposed method #01 can be applied in combination with other proposed method(s) within the scope where 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 between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed to determine the redundancy version (RV) and / or scrambling for the repeated transmission(s) in one or more of the following ways.

[0140] (1) For example, the same RV and / or scrambling may be applied to all repeat transmission(s).

[0141] (2) For example, the same RV and / or scrambling may be applied within a resource group to which OCC is applied, and different RVs and / or scrambling may be applied between resource groups to which OCC is applied.

[0142] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0143] For example, a resource group to which the above OCC applies may mean (time axis) resource(s) to which one OCC applies.

[0144] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[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, a method may be considered in which the terminal repeatedly transmits the uplink data channel (time-axis) and applies a (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, in order for the (time-axis) OCC to be effective, the data (e.g., or modulated symbols) of the repeatedly transmitted uplink data channel (e.g., PUSCH) may need to be identical. For example, even if the repeated transmissions of the uplink data channel are transmitted together with the OCC, if the redundancy version (RV) and / or scrambling for each repetition are different, orthogonality by the OCC code may not be guaranteed. For example, the present disclosure proposes a method for determining a redundancy version (RV) and / or scrambling for the repetitive transmission(s) in one or more of the following ways when a terminal can apply OCC between repetitive transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) during transmission of the uplink data channel (e.g., PUSCH).

[0146] (1) For example, the same RV and / or scrambling may be applied to all repeat transmission(s).

[0147] (2) For example, the same RV and / or scrambling may be applied within a resource group to which OCC is applied, and different RVs and / or scrambling may be applied between resource groups to which OCC is applied.

[0148] For example, according to the proposed method of the present disclosure, when repeatedly transmitting an uplink data channel (e.g., PUSCH) (in the time axis), there may be an advantage in that diversity operations for RV and / or scrambling can be supported while supporting OCC-based multiplexing.

[0149] For example, for RV cycling on OCC with PUSCH, the following may be considered:

[0150] - For example, Option 1: RV cycling could be used between OCC groups.

[0151] - - For example, note 1: RV cycling can be applied when the number of repetitions is greater than the OCC length.

[0152] - For example, Option 2: Fixed RVs can be used between OCC groups.

[0153] - For example, for option 3: OCC length 2, fixed RV is used between two OCC groups, and RV cycling can be used between groups of two OCC groups.

[0154] For example, the above proposed method #02 can be applied in combination with other proposed method(s) within the scope where the operations of the present disclosure do not conflict.

[0155] For example, proposal #03 can be proposed.

[0156] For example, according to Proposal #03, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), a scheme may be proposed that supports one or more of the following actions when the terminal skips transmission for all or part of the repeated transmissions of the uplink data channel (e.g., PUSCH) (due to a specific event).

[0157] (1) For example, OCC can be changed and applied to match the reduced number of repeated transmissions due to transmission omission.

[0158] (2) For example, both repeated transmission(s) of an uplink data channel (e.g., PUSCH) to be omitted and an uplink data channel (e.g., PUSCH) that is bound to an OCC may be omitted.

[0159] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0160] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0161] For example, the above transmission omission may include transmission omission due to multiplexing rules between uplink data channel(s) and / or uplink control channel(s) and / or transmission omission due to RF constraints and / or transmission power constraints of the terminal.

[0162] 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 OCC (time-axis) 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). For example, the terminal may omit transmission for a specific uplink data channel due to reasons such as transmission omission according to a multiplexing rule between uplink data channel(s) and / or uplink control channel(s) and / or transmission omission according to RF constraints and / or transmission power constraints of the terminal. For example, when the terminal repeatedly transmits an uplink data channel, all or part of the transmissions during the repeated transmissions may be omitted. For example, it may be assumed that the terminal repeatedly transmits an uplink data channel and applies an OCC between the repeated transmissions. For example, if only some of the repetitive transmission groups to which OCC is applied are skipped, the existing OCC is deformed so that orthogonality is no longer maintained, and thus transmissions among the repetitive transmission groups that are not skipped may interfere with the uplink data channel transmission of other terminals. For example, the present disclosure proposes a method for supporting one or more of the following operations when a terminal can apply OCC between repetitive transmissions of an uplink data channel (e.g., PUSCH) (in terms of time axis) when transmitting an uplink data channel (e.g., PUSCH), and when the terminal skips transmission for all or some of the repetitive transmissions of the uplink data channel (e.g., PUSCH) (due to a specific event).

[0163] (1) For example, OCC can be changed and applied to match the reduced number of repeated transmissions due to transmission omission.

[0164] (2) For example, both repeated transmission(s) of an uplink data channel (e.g., PUSCH) to be omitted and an uplink data channel (e.g., PUSCH) that is bound to an OCC can be omitted.

[0165] For example, in accordance with the proposed method of the present disclosure, there may be an advantage in that transmission omission can be supported in consideration of the interference effect on the uplink data channel of a multiplexed terminal when transmission omission occurs for all or part of the repetitive transmission of the uplink data channel.

[0166] For example, the above proposed method #03 can be applied in combination with other proposed method(s) within the scope where the operations of the present disclosure do not conflict.

[0167] Because NTN has a wider beam radius than TN, there may be many terminals within the beam, which may lead to a shortage of uplink capacity. Because NTN has a wider beam radius than TN, there may be many terminals within the beam, which may lead to a shortage of uplink resources.

[0168] For example, proposal #04 can be proposed.

[0169] For example, according to Proposal #04, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed in which the terminal supports multiplexing in one or more of the following ways when an uplink control channel (e.g., PUCCH) transmission occurs at the time of transmission of an uplink data channel (e.g., PUSCH) to which an OCC is applied.

[0170] (1) For example, OCC application can be disabled and uplink multiplexing rules for when OCC is not applied can be applied.

[0171] (2) For example, when an uplink data channel (e.g., PUSCH) that includes UCI is generated after applying the uplink multiplexing rule when OCC is not applied, UCI may be repeatedly transmitted in all of the repeated transmission(s) of the uplink data channel and the uplink data channel that are grouped with the same OCC.

[0172] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0173] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0174] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0175] 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 OCC (time-axis) between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, when an OCC is applied between the repeated transmissions of the uplink data channel, an uplink multiplexing rule needs to be considered. For example, it may be assumed that an uplink data channel (e.g., PUSCH) is repeatedly transmitted and an OCC is applied between the repeated transmissions. For example, assuming a case in which an OCC is not applied, it may be assumed that a multiplexing rule is applied to include uplink control information (UCI) for some of the repeated transmissions of the uplink data channels. For example, when transmitting only with UCI included in repetitive transmissions of some uplink data channels, the number of data symbols among the entire repetitive transmission(s) to which OCC is applied may not be the same due to the rate-matching process resulting from the inclusion of UCI, and thus data to which the complete OCC is not applied may occur. For example, the application of an incomplete OCC may cause interference effects on uplink transmissions using other OCCs.For example, the present disclosure proposes a method for supporting multiplexing in one or more of the following ways when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), and when an uplink control channel (e.g., PUCCH) transmission occurs at the time of transmission of an uplink data channel (e.g., PUSCH) to which an OCC is applied.

[0176] (1) For example, OCC application can be disabled and uplink multiplexing rules for when OCC is not applied can be applied.

[0177] (2) For example, when an uplink data channel (e.g., PUSCH) that includes UCI is generated after applying the uplink multiplexing rule when OCC is not applied, UCI may be repeatedly transmitted in all of the repeated transmission(s) of the uplink data channel and the uplink data channel that are grouped with the same OCC.

[0178] For example, in the case of following the proposed method of the present disclosure, there may be an advantage in that OCC application considering uplink multiplexing rules, such as a situation in which UCI is included in an uplink data channel, can be supported.

[0179] For example, if a non-repetitive PUCCH overlaps with an inter-slot OCC with PUSCH repetition in an OCC group, the following options may be considered:

[0180] - For example, Option 1: UCI can be dropped.

[0181] - - For example, FFS: whether all UCIs are dropped

[0182] - For example, Option 2: UCI is transmitted on PUCCH, and all PUSCH repetitions within the OCC group can be dropped.

[0183] - For example, Option 3: UCI can be multiplexed on PUSCH using inter-slot OCC.

[0184] 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.

[0185] Referring to FIG. 10, for example, PUSCH repetition may be performed. For example, the OCC length may be 4. For example, there may be a first OCC group and a second OCC group. UCI may be multiplexed.

[0186] - For example, option 3-a: UCI may be multiplexed on all PUSCH repetitions within an OCC group with inter-slot OCC. For example, UCI may be multiplexed on all PUSCH repetitions within the first OCC group.

[0187] - - - For example, FFS: Which OCC group

[0188] For example, unlike as shown in FIG. 10, the OCC length may not be limited to 4. For example, unlike as shown in FIG. 10, the number of OCC groups may not be limited to 2.

[0189] FIG. 11 illustrates an example of multiplexing for UCI according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure.

[0190] Referring to FIG. 11, for example, PUSCH repetition may be performed. For example, the OCC length may be 4. For example, there may be a first OCC group and a second OCC group. UCI may be multiplexed.

[0191] - For example, option 3-b: UCI may be multiplexed on PUSCH and OCC may not be applied within the OCC group. For example, UCI may be multiplexed on PUSCH and OCC may not be applied within the first OCC group.

[0192] For example, unlike as shown in FIG. 11, the OCC length may not be limited to 4. For example, unlike as shown in FIG. 11, the number of OCC groups may not be limited to 2.

[0193] FIG. 12 illustrates an example of multiplexing for UCI according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.

[0194] Referring to FIG. 12, for example, PUSCH repetition may be performed. For example, the OCC length may be 4. For example, there may be a first OCC group and a second OCC group. UCI may be multiplexed.

[0195] - For example, option 3-c: UCI may be multiplexed on PUSCH and OCC may not be applied within PUSCH repetitions. For example, UCI may be multiplexed on PUSCH and OCC may not be applied within all PUSCH repetitions. For example, UCI may be multiplexed on PUSCH and OCC may not be applied within the first OCC group and the second OCC group.

[0196] For example, unlike as shown in FIG. 12, the OCC length may not be limited to 4. For example, unlike as shown in FIG. 12, the number of OCC groups may not be limited to 2.

[0197] For example, note: the above combinations can be considered.

[0198] For example, FFS can specifically describe PUCCH and PUSCH timelines.

[0199] For example, FFS: Handling PUCCH with repetition

[0200] For example, FFS: handling different UCI types

[0201] When applying an orthogonal cover code between repetition(s) of an uplink shared channel in a slot-based manner, if any uplink shared channel repetition in the orthogonal cover code group overlaps with an uplink control channel, uplink capacity can be improved by multiplexing uplink control information on the uplink shared channel to which the orthogonal cover code is applied. When applying an orthogonal cover code between repetition(s) of an uplink shared channel in a slot-based manner, if any uplink shared channel repetition in the orthogonal cover code group overlaps with an uplink control channel, uplink control information can be multiplexed on the uplink shared channel, thereby reducing the shortage of uplink resources.

[0202] 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.

[0203] For example, proposal #05 can be proposed.

[0204] For example, according to Proposal #05, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed in which the base station and / or the terminal differently sets / determines the OCC application unit depending on the repetition type of the uplink data channel.

[0205] (1) For example, in case of slot-based repetitive transmission (e.g., PUSCH repetition type A), the OCC application unit can be set / determined as a multiple of the number of slots transmitting (single) TB.

[0206] (2) For example, in case of repeated transmission in units of symbol groups (e.g., PUSCH repetition type B), the OCC application unit can be set / determined as a multiple of the number of symbols transmitting (single) TB.

[0207] For example, applying OCC between repetitions of the above uplink data channel (in the time axis) may mean applying OCC in units of repeated transmissions.

[0208] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0209] 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 transmission of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, when the terminal repeatedly transmits the uplink data channel, the terminal may support one or more types of repeated transmission. For example, the terminal may repeatedly transmit the uplink data channel in units of slots (PUSCH Repetition Type A) or in units of symbol groups (or sub-slots) (PUSCH Repetition Type B). For example, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) when transmitting an uplink data channel, the base station and / or the terminal can set / determine an OCC application unit differently depending on the repetition type of the uplink data channel. For example, when performing slot-based repeated transmission, the base station and / or the terminal can set / determine an OCC application unit as a multiple of the number of slots transmitting a (single) TB, and when performing symbol group-based repeated transmission, the OCC application unit can be set / determined as a multiple of the number of symbols transmitting a (single) TB. For example, according to the proposed method of the present disclosure, the base station and / or the terminal can set / determine an appropriate OCC application unit depending on the repetition type of the uplink data channel of the terminal.

[0210] For example, the above proposed method #05 can be applied in combination with other proposed method(s) within the scope where the operations of the present disclosure do not conflict.

[0211] For example, proposal #06 can be proposed.

[0212] For example, according to Proposal #06, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed to apply both an OCC applied within a slot (Type 1 OCC) and an OCC applied between slots (Type 2 OCC).

[0213] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0214] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0215] 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 (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, when the terminal repeatedly transmits the uplink data channel, the terminal may support repeated transmissions in one or more types. For example, the terminal may repeatedly transmit the uplink data channel in units of slots (PUSCH repetition type A) or in units of symbol groups (or sub-slots) (PUSCH repetition type B). For example, OCC support between repeated transmissions of uplink data channels of different types needs to be considered. For example, an OCC application scheme that ensures orthogonality between slot-based repetitive transmissions and symbol group-based repetitive transmissions may be considered. For example, it may be assumed that a first terminal performs slot-based repetitive transmissions four times for four slots, a second terminal performs symbol group-based repetitive transmissions (half-slot length) eight times for four slots, and a third terminal performs symbol group-based repetitive transmissions (half-slot length) twice in the first slot out of four slots. For example, both intra-slot OCC and inter-slot OCC may be applied to ensure orthogonality between repetitive transmissions of the above terminals.For example, the base station and / or the terminal may configure / instruct the terminal to transmit an uplink data channel (e.g., PUSCH) by applying a Length-2 OCC in symbol group units (half the length of a slot) within a slot in the above example, and to transmit by applying a Length-4 OCC according to the total length of four slots between slots. For example, according to the proposed method of the present disclosure, there may be an advantage that OCC-based orthogonality may be supported even when the units and / or types of repeated transmissions of an uplink data channel (e.g., PUSCH) are different.

[0216] 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.

[0217] For example, proposal #07 can be proposed.

[0218] For example, according to the proposal method #07, when a terminal can apply an OCC (hereinafter, a first OCC) between repeated transmissions of an uplink data channel (e.g., a PUSCH) (in the time axis) when transmitting an uplink data channel (e.g., a PUSCH), a method for determining an OCC and / or CS to be applied to an RS within the uplink data channel based on the first OCC may be proposed.

[0219] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0220] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0221] For example, the above RS (reference signal) may mean DM-RS (demodulation reference signal) and / or PT-RS (phase tracking reference signal).

[0222] 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 transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, the terminal may determine an OCC and / or a cyclic shift (CS) for a reference signal (RS) based on an OCC value applied between repeated transmissions of the uplink data channel (e.g., PUSCH). For example, if OCC is not applied to an uplink data channel, the OCC of a PT-RS (phase tracking reference signal) is determined based on an RNTI value. However, if OCC is applied to an uplink data channel, it may be desirable to determine the OCC value for the PT-RS in conjunction with the OCC value applied to the data channel.

[0223] 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.

[0224] For example, proposal #08 can be proposed.

[0225] For example, according to the proposal method #08, when a terminal can apply an OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) when transmitting an uplink data channel (e.g., PUSCH), an OCC indexing method can be proposed such that a second-length OCC in the form of repeated first-length OCCs has the same index as the corresponding first-length OCC.

[0226] For example, applying OCC between repetitions of the above (time axis) uplink data channel may mean applying OCC in repetition transmission units (e.g., or multiples thereof).

[0227] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0228] For example, the above RS (reference signal) may mean DM-RS (demodulation reference signal) and / or PT-RS (phase tracking reference signal).

[0229] 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 OCC (time-axis) between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, it may be assumed that the OCC supports an OCC of a first length and an OCC of a second length (which is a multiple of the first length). For example, when the base station and / or the terminal apply an OCC between repeated transmissions of an uplink data channel (e.g., PUSCH), the base station and / or the terminal may apply an OCC of the second length or repeatedly apply an OCC of the first length, depending on the case. For example, it may be assumed that the first length is 2 slots and the second length is 4 slots. For example, when a base station multiplexes a first PUSCH having a length of 4 slots and a second PUSCH having a length of 4 slots, the base station may apply an OCC of a second length to the first PUSCH. For example, when a base station multiplexes a first PUSCH having a length of 4 slots and a second PUSCH and a third PUSCH having a length of 2 slots, the base station may want to repeatedly apply an OCC of a first length to the first PUSCH. For example, the present disclosure proposes an OCC indexing scheme in which, when a terminal can apply an OCC between repeated transmissions of an uplink data channel (e.g., a PUSCH) (in the time axis), a second length OCC in which an OCC of a first length is repeated has the same index as the corresponding first length OCC.For example, according to the proposed method of the present disclosure, there may be an advantage in that the implementation of a base station and / or a terminal becomes easier because the repeated application of an OCC of a first length is expressed as an OCC of a second length of the same index.

[0230] For example, the above proposed method #08 can be applied in combination with other proposed method(s) to the extent that the operations of the present disclosure do not conflict.

[0231] For example, proposal #09 can be proposed.

[0232] For example, according to Proposal #09, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed in which the terminal applies OCC (in time axis) in one or more of the following ways.

[0233] (1) For example, a method can be proposed in which a terminal applies (time axis) OCC based on a (time axis) resource grid.

[0234] (2) For example, a method may be proposed in which a terminal applies (time axis) OCC based on the transmission start point of an uplink data channel (e.g., PUSCH).

[0235] For example, applying OCC between repetitions of the above uplink data channel (in the time axis) may mean applying OCC in units of repeated transmissions.

[0236] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0237] For example, the base station can set / instruct which of the above methods(s) to apply.

[0238] For example, the above-mentioned (time axis) resource grid may be (pre-)promised between the base station and the terminal, or may be (pre-)configured and / or indicated by the base station. For example, there may be one or more (time axis) resource grids. For example, the above-mentioned (time axis) resource grids may be configured for each OCC length.

[0239] 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 a (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, the terminal may simply apply the (time-axis) OCC based on the transmission start point of the uplink data channel (e.g., PUSCH). For example, if the OCC supports a hierarchical structure such as a Walsh-Hadamard code, multiplexing between OCCs of different lengths may also be considered. For example, a PUSCH repeated transmission that is repeated in 4 slots when a length-4 OCC is applied and a PUSCH repeated transmission that is repeated in 2 slots when a length-2 OCC is applied can be distinguished from each other. For example, in order to satisfy orthogonality between OCCs with different lengths, the timing at which the OCC is applied may need to be adjusted according to specific conditions. For example, in the example of the length-4 OCC and the length-2 OCC, the length-2 OCC may be orthogonal to a code composed of the first and second values ​​or the code composed of the third and fourth values ​​of the length-4 OCC. For example, in the present disclosure, when a terminal can apply an OCC between repetitions of an uplink data channel (e.g., a PUSCH) when transmitting an uplink data channel, a method may be proposed in which the terminal applies an OCC (in the time axis) in one or more of the following ways.

[0240] (1) For example, a method can be proposed in which a terminal applies (time axis) OCC based on a (time axis) resource grid.

[0241] (2) For example, a method may be proposed in which a terminal applies (time axis) OCC based on the transmission start point of an uplink data channel (e.g., PUSCH).

[0242] For example, according to the proposed method of the present disclosure, there may be an advantage in that orthogonality between OCCs between repeated transmissions of uplink data channels with different starting points and / or lengths can be supported.

[0243] 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.

[0244] For example, proposal #10 could be proposed.

[0245] For example, according to the proposal method #10, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed in which some or all of the bit fields for indicating a Redundancy Version (RV) for repeated transmission of the uplink data channel are borrowed to indicate an OCC type and / or an OCC identifier (e.g., an OCC index) and / or an OCC length for the OCC.

[0246] For example, applying OCC between repetitions of the above uplink data channel (in the time axis) may mean applying OCC in units of repeated transmissions.

[0247] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0248] 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 a (time-axis) OCC between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, in order for the (time-axis) OCC to be effective, the data (e.g., or modulated symbols) of the repeatedly transmitted uplink data channel (e.g., PUSCH) may need to be identical. For example, even if the repeated transmissions of the uplink data channel are transmitted together with the OCC, if the redundancy version (RV) and / or scrambling for each repetition are different, orthogonality by the OCC code may not be guaranteed. For example, when OCC is applied to repetitive transmission of an uplink data channel, the RV value may be fixed or indicated in a simpler form. For example, the simplified RV may be indicated by utilizing only some bit(s) of an existing bit field for RV in dynamic control information such as DCI (dynamic control information), or no bit field may be needed at all. For example, the present disclosure proposes a method in which, when a terminal can apply OCC between repetitive transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) when transmitting an uplink data channel (e.g., PUSCH), some or all bit(s) of a bit field for RV in the case where OCC is not applied are utilized to indicate an OCC type and / or an OCC identifier and / or an OCC length in the case where OCC is applied.For example, in accordance with the proposed method of the present disclosure, when applying OCC for uplink repetitive transmission, there may be an advantage in that the size of (dynamic) control information for uplink transmission does not need to be unnecessarily expanded by (re)using the bit field for RV, which naturally loses its utility, to indicate OCC information.

[0249] For example, the above proposed scheme #10 can be applied in combination with other proposed scheme(s) to the extent that the operations of the present disclosure do not conflict.

[0250] For example, proposal #11 can be proposed.

[0251] For example, according to the proposal method #11, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) when transmitting an uplink data channel (e.g., PUSCH), a method may be proposed in which the OCC type and / or OCC identifier (e.g., OCC index) and / or OCC application unit for the OCC are set / indicated by the base station, and the OCC length is determined by the terminal according to the length / number of times of the repeated transmission.

[0252] For example, if an OCC matching the length / number of repetitions above is not set / indicated, the terminal may perform one or more of the following exception handling actions.

[0253] (1) For example, OCC may not be applied to repeated transmissions.

[0254] (2) For example, after selecting an OCC length greater than or equal to the repeat transmission, only a portion of the OCC can be applied to the repeat transmission.

[0255] (3) For example, after selecting an OCC length that is less than or equal to the repeated transmission, only a portion of the OCC can be applied to the repeated transmission or applied repeatedly.

[0256] For example, applying OCC between repetitions of the above uplink data channel (in the time axis) may mean applying OCC in units of repeated transmissions.

[0257] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[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 OCC (time-axis) between the repeated transmissions. For example, the (time-axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, when applying an OCC between the repeated transmissions, the OCC length may be associated with the length / number of times of the repeated transmissions. For example, the present disclosure may propose a method in which, when a terminal can apply an OCC between repeated transmissions of an uplink data channel (e.g., a PUSCH) (in terms of a time axis) when transmitting an uplink data channel (e.g., a PUSCH), an OCC type and / or an OCC identifier (e.g., an OCC Index) and / or an OCC application unit for the OCC are set / indicated by the base station, and the OCC length is determined by the terminal according to the length / number of times of the repeated transmission. For example, if the proposed method of the present disclosure is followed, there may be an advantage in that the signal transmission load for the base station to set / indicate the OCC length can be reduced. For example, if an OCC matching the length / number of times of the repeated transmission is not set / indicated, the terminal may perform one or more of the following exception handling operations.

[0259] (1) For example, OCC may not be applied to repeated transmissions.

[0260] (2) For example, after selecting an OCC length greater than or equal to the repeat transmission, only a portion of the OCC can be applied to the repeat transmission.

[0261] (3) For example, after selecting an OCC length that is less than or equal to the repeated transmission, only a portion of the OCC can be applied to the repeated transmission or applied repeatedly.

[0262] For example, when selecting and applying a smaller or equal OCC length, there may be an advantage in that it can support OCC-based multiplexing with other uplink data channels that have a smaller repetition transmission length / number of times. For example, when a Length-2 OCC and a Length-4 OCC can be set / indicated, it can be assumed that the terminal is instructed to transmit an uplink data channel (e.g., PUSCH) three times. For example, according to the proposed method of the present disclosure, the terminal (the first terminal) can apply the Length-2 OCC (the first OCC) for the first two repetition transmissions, and in the section where the first OCC is applied, another terminal (the second terminal) can transmit by applying the Length-2 OCC (the second OCC) orthogonal to the first OCC for the uplink data channel that has been repeatedly transmitted twice.

[0263] For example, the above proposed scheme #11 can be applied in combination with other proposed scheme(s) to the extent that the operations of the present disclosure do not conflict.

[0264] For example, proposal #12 could be proposed.

[0265] For example, according to Proposal #12, when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in time axis) when transmitting an uplink data channel (e.g., PUSCH), if an uplink control channel (e.g., PUCCH) transmission occurs at the time of transmission of an uplink data channel (e.g., PUSCH) to which an OCC is applied, a method may be proposed to support multiplexing in one or more of the following ways.

[0266] (1) For example, a method may be proposed in which the terminal first performs the UL multiplexing rules when OCC is not applied, and then performs additional exception handling when OCC is applied. For example, if the UL multiplexing rules when OCC is not applied are first performed, and then UCI is included in (a specific) repetitive transmission of an uplink data channel, the terminal (re)checks whether the processing time for UCI piggyback is appropriate based on the first transmission time within the resource group to which the same OCC is applied as the repetitive transmission, and if the processing time is appropriate, UCI is repeatedly transmitted within the resource group to which OCC is applied, and if not, the corresponding uplink data transmission may be omitted.

[0267] (2) For example, a method may be proposed in which the terminal defines UL multiplexing rules when OCC is applied separately from when OCC is not applied. For example, when OCC is applied, UL multiplexing rules may be defined that consider the processing time of the first uplink data channel of the resource group to which OCC is applied.

[0268] For example, the above UL multiplexing rule may mean an action performed by a terminal when transmission interval(s) of different multiple uplink transmission channel(s) (from the same terminal) overlap (in the time axis).

[0269] For example, applying OCC between repetitions of the above uplink data channel (in the time axis) may mean applying OCC in units of repeated transmissions.

[0270] For example, whether or not to apply the above OCC can be set / instructed by the base station.

[0271] 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 (in time axis) and applies an OCC (in time axis) between the repeated transmissions. For example, the (time axis) OCC may be for the purpose of multiplexing transmissions of one or more uplink data channels (e.g., PUSCH) (within the same cell). For example, when an OCC is applied between repeated transmissions of the uplink data channel, a two-way UL multiplexing rule may be considered. For example, the UL multiplexing rule may include a terminal operation when transmissions between uplink data channel(s) (e.g., PUSCH) and uplink control channel(s) (e.g., PUCCH) overlap (in time axis). For example, a method may be considered in which the terminal first performs the UL multiplexing rules when OCC is not applied, and then performs additional exception handling when OCC is applied. For example, after first performing the UL multiplexing rules when OCC is not applied, if UCI is included in a (specific) repetitive transmission of an uplink data channel, the terminal may (re)check whether the processing time for UCI piggybacking is appropriate based on the first transmission time point within the resource group to which the same OCC is applied as the repetitive transmission. If the processing time is appropriate, the UCI is repeatedly transmitted within the resource group to which OCC is applied; otherwise, the corresponding uplink data transmission may be omitted. For example, a method may be considered in which the terminal defines the UL multiplexing rules when OCC is applied separately from those when OCC is not applied. For example, when OCC is applied, a UL multiplexing rule may be defined that takes into account the processing time based on the first uplink data channel of the resource group to which OCC is applied.For example, according to the proposed method of the present disclosure, there may be an advantage of supporting UL multiplexing rules when a terminal can apply OCC between repeated transmissions of an uplink data channel (e.g., PUSCH) (in the time axis) when transmitting an uplink data channel (e.g., PUSCH).

[0272] For example, the above proposed scheme #12 can be applied in combination with other proposed scheme(s) to the extent that the operations of the present disclosure do not conflict.

[0273] FIG. 13 illustrates a method for a device 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.

[0274] Referring to FIG. 13, in step S1310, the device may obtain information related to an orthogonal cover code. In step S1320, the device may perform uplink shared channel repetition based on the orthogonal cover code. For example, the orthogonal cover code may be applied between the uplink shared channel repetitions. For example, based on the overlapping of at least one of the uplink shared channel repetitions and an uplink control channel, uplink control information related to the uplink control channel may be multiplexed on the uplink shared channel.

[0275] For example, based on at least one of the above uplink shared channel repetitions and the above uplink control channel overlapping, the above uplink control information may be multiplexed on the uplink shared channel repetitions within an orthogonal cover code group including the above uplink shared channel.

[0276] For example, the uplink shared channel repetition within the orthogonal cover code group may be all uplink shared channel repetitions within the orthogonal cover code group.

[0277] For example, based on at least one of the repetitions of the uplink shared channel and the overlapping of the uplink control channel, the uplink control information may be multiplexed on the uplink shared channel, and the orthogonal cover code may not be applied within the orthogonal cover code group including the uplink shared channel.

[0278] For example, based on at least one of the uplink shared channel repetitions and the uplink control channel overlapping, the uplink control information may be multiplexed on the uplink shared channel, and the orthogonal cover code may not be applied within the uplink shared channel repetition.

[0279] For example, the above orthogonal cover code may be an inter-slot orthogonal cover code.

[0280] For example, the orthogonal cover code between the slots may be an orthogonal cover code applied between repetitions of the uplink shared channel in which the uplink shared channel is repeated in slot units.

[0281] For example, based on at least one of the above uplink shared channel repetitions and the above uplink control channel overlapping, and based on remaining processing time for piggybacking of the above uplink control information, the above uplink control information may be multiplexed on the uplink shared channel. For example, the processing time for piggybacking of the above uplink control information may be based on a first uplink shared channel repetition within an orthogonal cover code group that includes at least one of the above uplink shared channel repetitions.

[0329] FIG. 17 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 17 can be combined with various embodiments of the present disclosure.

[0330] Referring to FIG. 17, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operations / functions of FIG. 17 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 16. The hardware elements of FIG. 17 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 16. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 16. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 16, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 16.

[0331] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 17. 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).

[0332] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010). The scramble sequence used for scrambling is generated based on an initialization value, and the initialization value may include ID information of the wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by a precoding matrix W of N*M. Here, N is the number of antenna ports, and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on complex modulation symbols. In addition, the precoder (1040) can perform precoding without performing transform precoding.

The time-frequency resources can include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. The signal generator (1060) generates a wireless signal from the mapped modulation symbols, and the generated wireless signal can be transmitted to another device through each antenna.

[0334] 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. 17. For example, a wireless device (e.g., 100, 200 of FIG. 16) 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.
