[0035] In the following description, "when, if, or in the case of" can be replaced with "based on".

[0036] The technical features described in one of the accompanying drawings of this disclosure may be implemented individually or simultaneously.

[0037] In this disclosure, higher-layer parameters can be parameters configured, pre-configured, or predefined for the UE. For example, a base station or network can send higher-layer parameters to the UE. For example, higher-layer parameters can be sent via Radio Resource Control (RRC) signaling or Media Access Control (MAC) signaling.

[0038] In this disclosure, the term "configured or defined" can be interpreted as pre-configuring or configuring a device via predefined signaling (e.g., SIB, MAC, RRC, downlink control information (DCI), etc.) from a base station or network. In this disclosure, the term "configured or defined" can also be interpreted as pre-configuring or configuring a device via predefined signaling (e.g., MAC, RRC, sidelink control information (SCI), control information signaled between devices, etc.) from another device. In this disclosure, the term "configured or defined" can be interpreted as pre-configuring a device.

[0039] In this disclosure, User Equipment (UE) may refer to a device, a portable device, a wireless device, etc. In this disclosure, Base Station (BS) may refer to a Radio Access Network (RAN) node, a Non-Terrestrial Network (NTN) cell / node, a Transmit / Receive Point (TRP), a network, an Integrated Access and Backhaul (IAB) node, a device, a portable device, a wireless device, etc.

[0040] The techniques proposed in this disclosure can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and Single Carrier Frequency Division Multiple Access (SC-FDMA). CDMA can be implemented using radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA can be implemented using radio technologies such as Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rate GSM Evolution (EDGE).

[0041] The technologies proposed in this disclosure can be implemented as 6G wireless technologies and can be applied to various 6G systems. For example, 6G systems can have key features such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), artificial intelligence (AI) integrated communication, tactile internet, high throughput, high network capacity, high energy efficiency, low backhaul and access network congestion, and enhanced data security.

[0042] Figure 1 The communication process between devices based on embodiments of the present disclosure is illustrated. Figure 1 The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0043] Reference Figure 1In step S101, the first device and the second device can perform synchronization. For example, the first device can be at least one of the UE and / or the devices proposed in this disclosure. For example, the second device can be at least one of the base station, network, RAN node, NTN node / cell, TRP, UE and / or the devices proposed in this 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 based on rules predefined by the second device. Here, for example, the synchronization signal can include multiple synchronization signals based on structure or purpose classification (e.g., primary synchronization signal, secondary synchronization signal, etc.). In this way, the first device can check the boundaries of the frames, subframes, time units, time slots and / or symbols of the second device, and the first device can obtain information for the second device (e.g., cell identifier).

[0044] In step S103, the first device may obtain system information sent by the second device. For example, the system information may include information related to the attributes, characteristics, and / or capabilities of the second device required to access the second device and use the service. For example, the system information may be categorized based on content (e.g., whether it is inherently necessary for access), transmission structure (e.g., the channel used, whether it is based on on-demand provision), etc. For example, the system information may be categorized into Main Information Blocks (MIBs) and System Information Blocks (SIBs). For example, the first device may send a signal requesting system information before receiving it, as needed. For example, the request and provision of system information may be performed after the random access procedure described later.

[0045] In step S105, the first device and the second device can perform a random access procedure. For example, the first device can send 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 the random access channel of the second device obtained through system information (e.g., channel location, channel structure, supported preamble structure, etc.). For example, the first device can send a preamble (e.g., Msg1) through the random access channel, and the first device can receive a random access response message (e.g., Msg2). The first device can also send 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 a single message (e.g., MsgA), and / or Msg2 and Msg4 can be sent and received as a single message (e.g., MsgB).

[0046] In step S107, the first and second devices can execute signaling for control information. Here, for example, the control information can be defined in various layers, such as layers controlling connections (e.g., Radio Resource Control (RRC) layer), layers handling the mapping between logical channels and transport channels (e.g., Medium Access Control (MAC) layer), layers handling physical channels (e.g., Physical (PHY) layer), etc. For example, the first and second devices can execute at least one of signaling for establishing a connection, signaling for determining communication-related configurations, and / or signaling for indicating allocated resources. For example, the control information can be signaled / sent via a control channel. For example, the control information and / or the control channel can be used to schedule data, data channels (e.g., shared channels), and / or control information on data channels.

[0047] In step S109, the first and second devices can transmit and / or receive data. For example, the first and second devices can process data based on signaling of control information and transmit and / or receive data. For example, when transmitting data, the first or second device can perform at least one of channel coding, 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 or second device can 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.

[0048] For example, the layers of the radio interface protocol between the first device and the second device can be classified as Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3), etc. For instance, the physical layer, belonging to Layer 1, can provide information transmission services using physical channels, and the Radio Resource Control (RRC) layer, located in Layer 3, can perform the function of controlling radio resources between the first and second devices. For this purpose, for example, the RRC layer can exchange RRC messages between the first and second devices.

[0049] Figure 2 A radio protocol architecture based on an embodiment of this disclosure is shown. Figure 2 The implementation methods can be combined with various embodiments of this disclosure, and some descriptions, functions, processes, proposals, methods, and / or operations of the implementation methods can be omitted. For example, Figure 2 (a) may show the radio protocol stack for the user plane used for uplink or downlink communication, and Figure 2 (b) may show the radio protocol stack for the control plane used for uplink or downlink communication. For example, Figure 2(c) can illustrate the radio protocol stack for the user plane used for inter-device communication, and Figure 2 (d) can show the radio protocol stack of the control plane used for inter-device communication.

[0050] For example, the physical layer can use physical channels to provide information transmission services to higher layers. For example, the physical layer can connect to the Media Access Control (MAC) layer, which is a higher layer, via a transport channel. For example, data can be transmitted between the MAC layer and the physical layer via a transport channel. For example, transport channels can be classified based on how and what characteristics are used to transmit data through the radio interface. For example, data can be transmitted between different physical layers (i.e., between the physical layers of a first device and a second device) via physical channels. For example, physical channels can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and time and frequency can be used as radio resources.

[0051] For example, the MAC layer can provide services to the higher-level Radio Link Control (RLC) layer via logical channels. For example, the MAC layer can provide mapping functionality from multiple logical channels to multiple transport channels. For example, the MAC layer can provide logical channel multiplexing functionality by mapping multiple logical channels to a single transport channel. For example, the MAC sublayer can provide data transmission services over logical channels.

[0052] 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) requirements of the Radio Bearer (RB), 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).

[0053] For example, the Radio Resource Control (RRC) layer can be defined only in the control plane. The RRC layer can be used to control logical, transport, and physical channels related to the configuration, reconfiguration, and release of radio bearers. For example, RB can refer to a logical path provided by first (e.g., the physical layer) and second layers (e.g., the MAC layer, RLC layer, Packet Data Convergence Protocol (PDCP) layer, Serving Data Adaptation Protocol (SDAP) layer, etc.) for data delivery between a first device and a second device.

[0054] For example, the PDCP layer in the user plane may include the delivery of user data, header compression, and encryption. Similarly, the PDCP layer in the control plane may include the delivery of control plane data and encryption / integrity protection.

[0055] For example, RB configuration can refer to the process of specifying radio protocol layers and channel attributes to provide a specific service and configuring each specific parameter and operating method. For instance, RBs can be divided into two types: Signaling Radio Bearers (SRBs) and Data Radio Bearers (DRBs). For example, an SRB can be used as a path for transmitting RRC messages in the control plane, and a DRB can be used as a path for transmitting user data in the user plane.

[0056] For example, the downlink transport 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 other control messages. For example, in the case of traffic or control messages in downlink multicast or broadcast services, they may be transmitted via the downlink SCH, or they may be transmitted via a separate downlink multicast channel (MCH). Meanwhile, the uplink transport 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 other control messages. For example, the logical channel located above the transport channel and mapped to the transport 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).

[0057] Figure 3 The structure of a radio frame based on an embodiment of this disclosure is shown. Figure 3 The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0058] Reference Figure 3 For example, radio frames can be used for uplink transmission, downlink transmission, and / or inter-device transmission. For example, a radio frame can be 10 ms long and can be defined as two 5 ms half-frames (HF). For example, a half-frame can include five 1 ms subframes (SF). For example, a subframe can be divided into one or more time slots, and the number of time slots within a subframe can be determined based on the subcarrier spacing (SCS). For example, based on the cyclic prefix (CP), each time slot can include 12 or 14 OFDM (A) symbols.

[0059] For example, in the case of using normal CP, each time slot may include 14 symbols. For example, in the case of using extended CP, each time slot may include 12 symbols. Here, for example, the symbols may include OFDM symbols (or CP-OFDM symbols) and / or single-carrier-FDMA (SC-FDMA) symbols (or discrete Fourier transform spread spectrum-OFDM (DFT-s-OFDM) symbols).

[0060] Table 2 below shows the number of symbols per slot (N) based on SCS configuration (u) when using normal CP or extended CP. slot symb Number of time slots per frame (N) frame,u slot ) and the number of time slots per subframe (N) subframe,u slot Examples of ).

[0061] [Table 2]

[0062] For example, OFDM(A) parameter sets (e.g., SCS, CP length, etc.) can be configured differently between multiple cells aggregated to a single UE. Correspondingly, the (absolute time) duration of time resources (e.g., subframes, time slots, or transmission time intervals (TTIs)) configured with the same number of symbols can be configured differently between the aggregated cells. For example, in this disclosure, time resources such as subframes, time slots, TTIs, etc., can be referred to as time units.

[0063] For example, multiple parameter sets or SCSs can be supported to support various services. For instance, with an SCS of 15kHz, wide-area coverage in conventional cellular bands can be supported, while with an SCS of 30kHz / 60kHz, dense urban areas, lower latency, and wider carrier bandwidth can be supported. For instance, with an SCS of 60kHz or higher, bandwidths greater than 24.25GHz can be supported to overcome phase noise.

[0064] Figure 4 The time slot structure of a frame based on an embodiment of this disclosure is shown. Figure 4 The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0065] Reference Figure 4For example, a time slot can include multiple symbols in the time domain. For example, a carrier can include multiple subcarriers in the frequency domain. For example, a resource block (RB) can be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth portion (BWP) can be defined as multiple consecutive (physical) resource blocks ((P)RBs) in the frequency domain and can correspond to a set of parameters (e.g., SCS, CP length, etc.). For example, a carrier can include up to N BWPs (where N is a positive integer). For example, data communication can be performed by activating BWPs. For example, each element in a resource grid can be called a resource element (RE), and a complex symbol can be mapped to each element.

[0066] For example, a BWP can be a set of consecutive PRBs in a given parameter set. For example, a PRB can be selected from a subset of consecutive common resource blocks (CRBs) in a given parameter set on a given carrier.

[0067] For example, a BWP can be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, a UE may not monitor downlink radio link quality in a DL BWP other than the active DL BWP on the primary cell (PCell). For example, a UE may not receive the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), or Channel State Information Reference Signal (CSI-RS) (except for Radio Resource Management (RRM)) other than the active DL BWP. For example, a UE may not trigger Channel State Information (CSI) reporting for an inactive DL BWP. For example, a UE may not transmit the Physical Uplink Control Channel (PUCCH) or Physical Uplink Shared Channel (PUSCH) other than the active UL BWP. For example, in the downlink case, the initial BWP can be given as a set of contiguous resource blocks (RBs) for the Residual Minimal System Information (RMSI) Control Resource Set (CORESET) (configured by the Physical Broadcast Channel (PBCH)). For example, in the uplink case, the initial BWP can be given by a System Information Block (SIB) for the random access procedure. For example, the default BWP can be configured by higher layers. For example, the initial value of the default BWP can be the initial DL BWP. To save energy, if the UE does not detect downlink control information (DCI) for a certain period of time, the UE can switch its active BWP to the default BWP.

[0068] Figure 5 An example of a BWP based on an embodiment of this disclosure is shown. Figure 5 The implementation methods can be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods, and / or operations of the implementation methods can be omitted. Figure 5 In this implementation, it is assumed that there are three BWPs.

[0069] Reference Figure 5 For example, a common resource block (CRB) can be a carrier resource block numbered from one end of a carrier frequency band to the other, and a PRB can be a resource block numbered within each BWP. For example, point A can indicate a common reference point of the resource block grid.

[0070] For example, a BWP can be configured by point A, the offset from point A, and the bandwidth NstartBWP. For example, point A can be an external reference point of the PRB of a carrier, where all parameter sets (e.g., all parameter sets supported by the network on the corresponding carrier) are 0-aligned with subcarriers. For example, the offset can be the PRB spacing between the lowest subcarrier in a given parameter set and point A. For example, the bandwidth can be the number of PRBs in a given parameter set.

[0071] Figure 6 This illustrates a communication structure that can be provided in a 6G system based on an embodiment of this disclosure. Figure 6 The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0072] As core implementation technologies for 6G systems, technologies such as artificial intelligence (AI), terahertz (THz) communication, optical wireless technology, free-space light (FSO) backhaul networks, massive MIMO technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, non-cellular communication, wireless information and power transfer (WIET), integrated sensing and communication, integrated access and backhaul networks, holographic beamforming, big data analytics, and large-scale intelligent surfaces (LIS) can be adopted.

[0073] - Artificial Intelligence (AI): When AI is introduced into communication, real-time data transmission can be simplified and improved. AI can use numerous analyses to determine methods for performing complex target tasks. For example, AI can increase efficiency and reduce processing latency. Time-consuming operations such as switching, network selection, and resource scheduling can be performed instantly by AI. AI can also play an important role in M2M, machine-to-human, and human-to-machine interactions. Additionally, AI can enable instant communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, smart structures, smart networks, smart devices, intelligent cognitive radios, self-maintaining wireless networks, and machine learning.

[0074] - Terahertz (THz) Communication: Data rates can be increased by increasing bandwidth. This can be achieved by using sub-THz communication with wide bandwidth and applying advanced massive MIMO technology. THz waves are referred to as submillimeter radiation, typically indicating a frequency band between 0.1THz and 10THz with corresponding wavelengths ranging from 0.03mm to 3mm. The 100GHz to 300GHz band (sub-THz band) is considered the main part of the THz band used for cellular communication. 6G cellular communication capacity increases when the sub-THz band is added to the millimeter-wave band. The defined THz band of 300GHz to 3THz is in the far-infrared (IR) band. The 300GHz to 3THz band is part of the optical band, but it lies at the boundary of the optical band and immediately follows the RF band. Therefore, the 300GHz to 3THz band is similar to RF. The main characteristics of THz communication include (i) a wide bandwidth that can be used to support very high data rates and (ii) high path loss at high frequencies (highly directional antennas are essential). The narrow beamwidth generated in highly directional antennas reduces interference. The short wavelength of THz signals allows for the integration of a greater number of antenna elements with devices and base stations operating in this band. Therefore, advanced adaptive placement techniques capable of overcoming range limitations can be used.

[0088] - Advanced Air Mobility (AAM): AAM can be a broad concept encompassing Urban Air Mobility (UAM), Regional Air Mobility (RAM), and Unmanned Aircraft Systems (UAS). For example, AAM can include UAM, RAM, UAS, and Unmanned Aircraft (UAV).

[0089] - Autonomous driving (self-driving): Vehicle-to-everything (V2X), a core element in establishing autonomous driving infrastructure, can be a technology that enables vehicles to communicate and share with various elements on the road for autonomous driving, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I).

[0090] - Non-terrestrial Network (NTN): NTN can refer to a network or network segment that uses radio frequency (RF) resources installed on a satellite (or UAS platform). NTN services can be considered to ensure wider coverage or to provide wireless communication services to areas where installing wireless communication base stations is difficult.

[0091] - Integrated Sensing and Communication (ISAC): Wireless sensing is a technology enabler that acquires information about the characteristics of the environment and / or objects within the environment. It uses radio frequency to determine the distance (range), angle, or instantaneous linear velocity of objects.

[0092] - Reconfigurable Smart Surfaces (RIS): RIS can be used to manipulate and enhance signal propagation in wireless communication environments. For example, an RIS can consist of a metasurface or many small antennas arranged on a surface, and each small antenna can actively adjust the phase, amplitude, polarization, etc., of the reflected signal. For example, an RIS can improve signal reception by adjusting the path, phase, and / or intensity of the propagating signal. For example, in the case of an RIS, power consumption can be very low because power is consumed only for adjusting the phase and amplitude of the small antennas. For example, because an RIS can be reconfigured according to various environments, it can meet various communication requirements and can operate effectively in dynamic network environments.

For example, for purposes such as coverage enhancement, devices such as satellite networks, HIBS, and UEs capable of over-the-air communication (e.g., AAM) can act as relays. For example, an AAM can communicate with base stations, satellite networks, etc., and / or an AAM can communicate directly with a UE, another AAM, etc.

Figure 8a and Figure 8b The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0096] Figure 8a This illustrates a non-terrestrial network scenario based on a transparent payload, and Figure 8b This illustrates a non-terrestrial network scenario based on regenerative payloads. For example, a non-terrestrial network may typically include the following components.

[0097] - Connecting a non-terrestrial network to one or more satellite gateways that connect to a public data network.

[0098] - Feed link or wireless link between the satellite gateway and the satellite (or UAS platform)

[0099] - Service link or radio link between User Equipment (UE) and satellite (or UAS platform)

[0100] - Satellites (or UAS platforms) capable of implementing transparent or regenerative payloads (including onboard processing). For example, a satellite (or UAS platform) can typically generate multiple beams over a given service area defined by line-of-sight. For example, the beam coverage area can typically be elliptical. For example, the line-of-sight of the satellite (or UAS platform) can vary based on the onboard antenna pattern and minimum elevation angle. For example, for transparent payloads, RF filtering, frequency conversion, and amplification can be performed. Therefore, repetitive waveform signals in the payload can remain unchanged. For example, for regenerative payloads, RF filtering, frequency conversion, and amplification, as well as demodulation / decoding, switching, and / or routing, and encoding / modulation can be performed. This can be effectively equivalent to installing all base station functions on a satellite (or UAS platform).

[0101] - Optional, inter-satellite link (ISL); - User equipment can be served by satellites (or UAS platforms) within the target service area.

[0102] Figure 9 The process of performing downlink transmission and reception based on an embodiment of this disclosure is illustrated. Figure 9 The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0103] Reference Figure 9 In step S910, the base station can schedule downlink transmissions, such as frequency / time resources, transport layer, downlink precoder, modulation and coding scheme (MCS), etc. For example, the base station can determine the beam used for PDSCH transmission to the UE.

[0104] In step S920, the UE can receive DCI for downlink scheduling (e.g., scheduling information including PDSCH) from the base station on the PDCCH.

[0105] For example, DCI format 1_0 or 1_1 can be used for downlink scheduling. For example, DCI format 1_1 may include the following information: DCI format identifier, bandwidth portion indicator, frequency domain resource allocation, time domain resource allocation, bundle size indicator, rate matching indicator, zero power (ZP) CSI-RS trigger, antenna port, transmission configuration indicator (TCI), sounding reference signal (SRS) request, and demodulation reference signal (DMRS) sequence initialization.

[0106] For example, the number of DMRS ports can be scheduled based on each state indicated in the antenna port field, and single-user (SU) / multi-user (MU) transmission scheduling can also be performed.

[0107] For example, the TCI field can be configured with 3 bits and can dynamically indicate the quasi-co-address (QCL) for DMRS by indicating up to 8 TCI states based on the TCI field value.

[0108] In step S930, the UE can receive downlink data from the base station on the PDSCH.

[0109] For example, if the UE detects a PDSCH that includes DCI format 1_0 or 1_1, the UE can decode the PDSCH based on the indication of the corresponding DCI.

[0110] Figure 10 The process of performing uplink transmission and reception based on an embodiment of this disclosure is illustrated. Figure 10 The implementation methods may be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods may be omitted.

[0111] Reference Figure 10 In step S1010, the base station can schedule uplink transmissions, such as frequency / time resources, transport layer, uplink precoder, modulation and coding scheme (MCS), etc. For example, the base station can determine the beam used for PUSCH transmission of the UE.

[0112] In step S1020, the UE can receive DCI for uplink scheduling (e.g., scheduling information including PUSCH) from the base station on the PDCCH.

[0113] For example, DCI format 0_0 or 0_1 can be used for uplink scheduling. For example, DCI format 0_1 ​​can include the following information: DCI format identifier, UL / Supplementary Uplink (SUL) indicator, bandwidth portion indicator, frequency domain resource allocation, time domain resource allocation, frequency hopping flag, modulation and coding scheme (MCS), SRS resource indicator (SRI), precoding information and layer number, antenna port, SRS request, DMRS sequence initialization, and uplink shared channel (UL-SCH) indicator.

[0114] For example, the SRS resources configured within the SRS resource set associated with the high-level parameter "usage" can be indicated by the SRS resource indicator field. For instance, "spatialRelationInfo" can be configured for each SRS resource, and its value can be one of {CRI, SSB, SRI}.

[0115] In step S1030, the UE can send uplink data to the base station on the PUSCH.

[0116] For example, if the UE detects a PDCCH containing DCI format 0_0 or 0_1, the UE can send the corresponding PUSCH according to the indication of the corresponding DCI. For example, for PUSCH transmission, two transmission schemes can be supported: codebook-based transmission and non-codebook-based transmission.

[0117] For example, if the higher-layer parameter "txConfig" is set to "codebook", the UE can be configured for codebook-based transmission. Conversely, if the higher-layer parameter "txConfig" is set to "nonCodebook", the UE can be configured for non-codebook-based transmission. For example, if the higher-layer parameter "txConfig" is not configured, the UE may not expect to be scheduled by DCI format 0_1. For example, if PUSCH is scheduled by DCI format 0_0, PUSCH transmission can be based on a single antenna port.

[0118] Figure 11Examples of common timing advance (TA) and UE-specific TA based on embodiments of this disclosure are shown. Figure 11 The implementation methods can be combined with various implementation methods of this disclosure, and some descriptions, functions, processes, proposals, methods and / or operations of the implementation methods can be omitted.

[0119] Reference Figure 11 It can obtain UE-specific TAs to compensate for transmission delays on the service link, and can obtain common TAs to compensate for transmission delays between the reference point (RP) and the satellite.

[0120] For example, in an NTN-based communication system, the UE can calculate the TA based on the UE's Global Navigation Satellite System (GNSS) capabilities (e.g., UE location) and orbit-related high-level parameters transmitted from the base station, and this can be referred to as the UE-specific TA (NTN). UE TA,adj For example, if no orbit-related higher-layer parameters are received from the base station, the UE-specific TA can be set to 0. For example, the TA obtained based on common TA parameters (e.g., TACommon, TACommonDrift, and / or TACommonDriftVariation) from the higher-layer parameters sent from the base station can be referred to as the common TA (N). common TA,adj For example, if no common TA parameter is sent from the base station, the common TA can be set to 0. Therefore, for example, in an NTN-based communication system, the total TA value (T...) TA ) can be obtained as "(N TA + N TA,offset + N common TA,adj +N UE TA,adj ) Tc". For example, N TA,offset This can refer to the TA offset value provided to the UE for each serving cell, and N TA It can refer to the value obtained based on the timed advance command.

[0121] In embodiments of this disclosure, half-duplex operation may include the following operations.

[0122] For example, a half-duplex (HD) UE may not expect to detect the DCI format of the reception of a set of symbols scheduled as well as the DCI format of the transmission in any of the symbols scheduled in that set of symbols.

[0123] For example, if the UE's PDCCH reception includes two PDCCH candidates, the end of the later PDCCH candidate can be the end of the PDCCH reception.

[0124] For example, an HD-UE may not expect to detect the dedicated higher-layer parameters that configure the reception of a set of symbols, as well as the DCI format that schedules the transmissions in any of those symbols.

[0125] For example, in the absence of a DCI format indicating the transmission of PUSCH, PUCCH, PRACH, SRS of at least one symbol in the group of symbols, reception of the higher-layer configuration of PDCCH, PDSCH, CSI-RS and / or DL ​​PRS in the group of symbols can be performed.

[0126] For example, in the case of comparing (vs.) the CSI-RS and PDSCH indicated by the DCI format in the high-layer configuration of PUCCH and PUSCH, if the last symbol received from the PDCCH used for the DCI format is in T... proc,2 If the memory contains the first symbol in the UL transmission, the UE may not cancel the UL transmission; otherwise, the UE may cancel the UL transmission.

[0127] For example, in the case of SRS comparison (vs.) with DCI format indication of CSI-RS and PDSCH in high-level configuration, the signal received from the last symbol of the PDCCH used for DCI format is in T proc,2 SRS transmissions within a given period may not be cancelled, and SRS transmissions of remaining residual symbols may be cancelled.

[0128] For example, T proc,2 It could be assumption d 2,1 =1 is used for PUSCH preparation time for UE processing capability 1, and μ can correspond to the minimum SCS configuration among the SCS configuration of PDCCH carrying DCI format and SRS, PUCCH and PUSCH.

[0129] For example, it is not desirable to simultaneously receive the Type-0 / 0A / 1 / 2-PDCCH CSS set configuration and the dedicated high-level parameters for configuring the transport in that set of symbols within a single set of symbols.

[0130] For example, in a high-level configuration where the PUSCH and PUCCH are compared (vs.) and there is an SSB within the DL BWP indicated by NonCellDefiningSSB or ServingCellConfigCommon or by ssb-PositionInBurst in SIB1, the PUSCH and PUCCH transmissions can be omitted if the TX-RX switching period is not guaranteed before the next earliest SSB, and / or if the RX-TX switching period is not guaranteed after the previous latest SSB.

[0131] For example, in a high-level configuration SRS comparison (vs.) where there is an SSB within the DL BWP indicated by ssb-PositionInBurst in NonCellDefiningSSB or ServingCellConfigCommon or SIB1, the SRS of symbols not preceding the TX-RX switching time period of the next earliest SSB may not be transmitted, and / or the SRS of symbols not following the RX-TX switching time period of the previous latest SSB may not be transmitted.

[0132] For example, in a comparison (vs.) of PRACH, PUSCH, PUCCH based on the PDCCH order where there is an SSB within the DL BWP indicated by NonCellDefiningSSB, ServingCellConfigCommon, or ssb-PositionInBurst in SIB1, the UL transmission can be omitted if any symbol overlaps with the symbol duration of the SSB.

[0133] For example, in the case where there is an SSB in the DL BWP indicated by NonCellDefiningSSB, ServingCellConfigCommon, or ssb-PositionInBurst in SIB1, the SRS may not be transmitted during the symbol duration of the SSB.

[0134] For example, when comparing the reception of PRACH or MsgA PUSCH triggered at a higher layer with that of PDCCH, PDSCH, CSI-RS, and DL PRS, and comparing the presence of an SSB within a DL BWP indicated by ssb-PositionInBurst in NonCellDefiningSSB, ServingCellConfigCommon, or SIB1, this can be implemented by the UE if the symbol durations overlap, and this can also be implemented by the UE if the TX-RX or RX-TX handover period is not guaranteed.

[0135] Recently, the introduction of non-terrestrial networks (NTNs) utilizing satellites as network nodes has been actively discussed in the communications field. Satellites supporting NTNs can be classified according to their flight orbits and characteristics, such as Geostationary Earth Orbit (GEO), Medium Earth Orbit (MEO), and Low Earth Orbit (LEO), and typically have very high altitudes. Here, NTNs can provide services for Reduced Capability (RedCap) UEs and / or Enhanced Reduced Capability (eRedCap) UEs supporting half-duplex frequency division duplex (HD-FDD) transmission schemes. However, UEs supporting half-duplex transmission schemes cannot simultaneously perform DL reception and UL transmission, thus requiring the definition of rules for base station (or network) and / or UE operation when DL reception and UL transmission times overlap and / or conflict on the time axis (hereinafter referred to as DL / UL conflict handling rules). Here, it is necessary to consider issues such as information that needs to be prioritized in the NTN and / or timing advance (TA) mismatch between the base station and the UE caused by the UE's autonomous application of timing advance (TA) in the NTN, in order to define the DL / UL conflict handling rules for UEs operating in half-duplex transmission mode in the NTN.

[0136] For example, in NTN communication, due to the large and variable propagation delay, the base station may have difficulty identifying the UE's accurate TA, and / or if the UE applies the TA autonomously, the UE may perform transmissions in time intervals outside the uplink time intervals (e.g., uplink slots, uplink subframes, uplink TTIs, etc.) expected by the base station. In this case, for example, if the uplink transmission overlaps with the downlink time interval, a collision may occur. Figure 12 This shows an example of a conflict caused by a TA mismatch. (See also...) Figure 12 If the TA between the UE and the base station matches, then uplink transmissions by the UE in time interval #A may not conflict with the downlink time interval of the base station. On the other hand, if the TA between the UE and the base station does not match, then uplink transmissions by the UE in time interval #B may conflict with the downlink time interval of the base station (e.g., Figure 12 The time interval in #C) is in conflict.

[0137] In the following, this disclosure proposes a transmission method for a UE operating in half-duplex transmission mode in an NTN and an apparatus supporting the transmission method, from the perspective of DL / UL conflict handling rules.

[0138] [Selection of Criteria for Determining DL / UL Conflict Resources]

[0139] [Proposal #01] In a non-terrestrial network, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to the half-duplex transmission mode, when the base station (or network) and / or UE identify conflicting DL / UL resources, the conflicting DL / UL resources can be identified through one or more of the following schemes based on the (pre-)configured and / or agreed scheme between the base station (or network) and UE.

[0140] (1) First approach: The conflicting (potential) UL transmission interval can be derived based on DL (assuming timing advance (TA) corresponds to a specific range). For example, for a specific DL resource / slot, the conflicting (potential) UL transmission interval (assuming TA corresponds to a specific range) can refer to: a UL resource interval with a start time of a time / symbol that is applied with a first (time) offset relative to a UL resource / slot with the same time index as the DL resource / slot (hereinafter referred to as the reference UL resource / slot), and an end time of a time / symbol that is applied with a second (time) offset relative to the reference UL resource / slot.

[0141] (2) Second option: The conflicting (potential) DL transmission interval can be derived based on UL (assuming that the timing advance (TA) corresponds to a specific range). For example, for a specific UL resource / slot, the conflicting (potential) DL transmission interval (assuming that the TA corresponds to a specific range) can refer to: the DL resource interval that starts at a time / symbol that is ahead of a first (time) offset compared to a DL resource / slot with the same time index as the UL resource / slot (hereinafter referred to as the reference DL resource / slot), and ends at a time / symbol that is behind the reference UL resource / slot by a second (time) offset.

[0142] Here, for example, the first (time) offset and / or the second (time) offset can be values ​​that are (pre-)agreed and / or configured between the base station (or network) and the UE. Here, for example, the first (time) offset and / or the second (time) offset can include one or more elements, and one of these elements can include a (common) TA.

[0143] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot perform DL reception and UL transmission simultaneously, and if the DL reception time and UL transmission time conflict, the UE can prioritize DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station.

[0144] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values.

[0145] Here, for example, due to reasons such as (UE)TA applications, there may be situations in non-terrestrial networks where the base station (or network) and the UE may have different mutual identification of conflicting DL / UL resources. For example, when determining the UL resource / time slot that conflicts with a specific DL resource / time slot, there may be cases where the location of the UL resource / time slot determined to conflict with the corresponding DL resource / time slot differs by several time slots between the base station (or network) and the UE.

[0146] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to the half-duplex transmission mode, when the base station (or network) and / or UE identify conflicting DL / UL resources, they can identify the conflicting DL / UL resources based on a scheme (pre-configured) and / or (pre-agreed) between the base station (or network) and UE, assuming that the TA corresponds to a specific range. For example, when determining a UL resource / time slot that conflicts with a (specific) DL resource / time slot, the base station (or network) and / or UE can identify the following UL resource intervals as potential conflict intervals: UL resource intervals with a time / symbol applied with a first (time) offset relative to a UL resource / time slot having the same time index as the (specific) DL resource / time slot (hereinafter referred to as the reference UL resource / time slot) as the start time, and a time / symbol applied with a second (time) offset relative to the reference UL resource / time slot as the end time. Alternatively, for example, when determining a DL resource / slot that conflicts with a (specific) UL resource / slot, the base station (or network) and / or UE may identify the following DL resource intervals as potential conflict intervals: DL resource intervals with a first (time) offset applied to a DL resource / slot having the same time index as the (specific) UL resource / slot (hereinafter referred to as the reference DL resource / slot) as the start time and a second (time) offset applied to the reference DL resource / slot as the end time.

[0147] Based on the proposed scheme of this disclosure, even when the TA values ​​identified between the base station (or network) and the UE differ in a non-terrestrial network, there is an advantage in being able to share a common identification of (potential) DL / UL conflicting resources. In this way, the base station (or network) and the UE can have the same understanding and / or expectation of the objectives and / or results of the execution of DL / UL conflict rules.

[0148] The above-mentioned [Proposal #01] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0149] [Proposal #02] In non-terrestrial networks, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to half-duplex transmission mode, then when the base station (or network) configures / indicates (dynamically scheduled and / or semi-statically configured) DL (or UL) resources to the UE, it can also configure / indicate whether the DL (or UL) resources are preferred over the (dynamically scheduled and / or semi-statically configured) UL (or DL) resources. Here, for example, DL resources may include PDCCH and / or PDSCH and / or CSI-RS. Here, for example, UL resources may include PUCCH and / or PUSCH and / or SRS and / or PRACH.

[0150] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0151] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0152] Here, for example, due to reasons such as (UE)TA applications, DL / UL conflicts may occur in non-terrestrial networks, even in situations that could traditionally be avoided through scheduling between the base station (or network) and the UE. For instance, according to traditional DL / UL conflict handling rules, if a dynamically scheduled DL reception conflicts with a dynamically scheduled UL transmission, the UE expects the base station (or network) not to cause the corresponding situation and considers it an error. However, in non-terrestrial networks, the aforementioned situation may occur because the base station (or network) cannot accurately know the DL / UL conflicting resources from the UE's perspective.

[0153] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to the half-duplex transmission mode, when the base station (or network) configures / indicates (dynamically scheduled and / or semi-statically configured) DL (or UL) resources to the UE, it can also configure / indicate whether the DL (or UL) resource is a resource that takes precedence over the (dynamically scheduled and / or semi-statically configured) UL (or DL) resources.

[0154] Based on the proposed scheme of this disclosure, if an unexpected DL / UL conflict occurs in a non-terrestrial network due to a difference in the TA value identified between the base station (or network) and the UE, it has the advantage of being able to prioritize the reception / transmission of one of the DL and UL based on the same understanding of the scheme (pre-)agreed and / or (pre-configured) between the base station (or network) and the UE.

[0155] The above-mentioned [Proposal #02] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0156] [Priority Determination Between DL / UL Conflicting Resources]

[0157] [Proposal #03] In a non-terrestrial network, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled DL receive resource / slot (hereinafter referred to as the first DL transmission) (e.g., PDSCH), the UE can deduce the (potential) UL transmission interval experiencing the conflict (hereinafter referred to as the first UL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled UL transmission resources / slots (hereinafter referred to as the first UL transmission) within the first UL conflict interval, the UE can determine the transmission to be prioritized between the first DL transmission and the first UL transmission (within the first UL conflict interval) in the following manner.

[0158] (1) If at least one or more first UL transmissions and / or all first UL transmissions have a higher priority than the first DL transmissions, then the first UL transmissions (within the first UL conflict interval) may be performed first.

[0159] (2) In other cases, the first DL transmission can be performed first.

[0160] Here, for example, for the first DL transmission and the first UL transmission, there may be only one with a higher or lower priority than the other. Here, for example, for a specific DL resource / slot, a conflicting (potential) UL transmission interval (assuming the TA corresponds to a specific range) can refer to: a UL resource interval that starts with a time / symbol applied to a UL resource / slot with the same time index as the DL resource / slot (hereinafter referred to as the reference UL resource / slot) and ends with a time / symbol applied to the reference UL resource / slot. Here, for example, the first (time) offset and / or the second (time) offset can be values ​​(pre-)agreed and / or configured between the base station (or network) and the UE. Here, for example, the first (time) offset and / or the second (time) offset can include one or more elements, and one of these elements can include the (common) TA. Here, for example, the priority can follow (pre-)agreed and / or (pre-)configured between the base station (or network) and the UE. Here, for example, the base station (or network) may (in advance) agree and / or configure / instruct the UE whether to perform the operation and / or which operation to perform.

[0161] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0162] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0163] Here, for example, due to reasons such as (UE)TA applications, in non-terrestrial networks, the base station (or network) and / or UE can identify UL resources / slots that conflict with (specific) DL resources / slots as a series of intervals. For example, a UE can experience conflicting (potential) UL transmission intervals (hereinafter referred to as the first UL conflict interval) for configured and / or scheduled DL receive resources / slots (hereinafter referred to as the first DL transmission) (e.g., PDSCH) (assuming that the timing advance (TA) corresponds to a specific range). Here, for example, in order to support correct signal transmission / reception operation considering half-duplex transmission modes, it is necessary to pre-establish a mutual agreement between the base station (or network) and / or UE regarding the priority of transmissions between the first DL transmission and the first UL transmission (within the first UL conflict interval).

[0164] Therefore, in this disclosure, if there are at least one or more configured and / or scheduled UL transmission resources / slots (hereinafter referred to as the first UL transmission) within the first UL conflict interval, the UE can determine the transmission to be prioritized between the first DL transmission and the first UL transmission (within the first UL conflict interval) in the following manner.

[0165] (1) If at least one or more first UL transmissions and / or all first UL transmissions have a higher priority than the first DL transmissions, then the first UL transmissions (within the first UL conflict interval) may be performed first.

[0166] (2) In other cases, the first DL transmission can be performed first.

[0167] Based on the proposed scheme of this disclosure, when the base station (or network) and the UE mutually identify potentially conflicting UL transmission intervals for (specific) DL transmissions by reflecting TA uncertainty in a non-terrestrial network, it has the advantage of being able to smoothly support the UE's half-duplex mode operation based on a clear protocol on which transmission, DL transmission or UL transmission interval, is prioritized.

[0168] The above-mentioned [Proposal #03] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0169] [Proposal #04] In a non-terrestrial network, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled UL transmission resource / slot (hereinafter referred to as the first UL transmission) (e.g., PUSCH), the UE can deduce the (potential) DL transmission interval experiencing the conflict (hereinafter referred to as the first DL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled DL receive resources / slots (hereinafter referred to as the first DL transmission) within the first DL conflict interval, the UE can determine the transmission to be prioritized between the first UL transmission and the first DL transmission (within the first DL conflict interval) in the following manner.

[0170] (1) If at least one or more first DL transmissions and / or all first DL transmissions have a higher priority than the first UL transmission, then the first DL transmissions (within the first DL conflict interval) may be performed first.

[0171] (2) In other cases, the first UL transmission can be prioritized.

[0172] Here, for example, for the first DL transmission and the first UL transmission, there may be only one with a higher or lower priority than the other. Here, for example, for a specific UL resource / slot, a conflicting (potential) DL transmission interval (assuming the TA corresponds to a specific range) can refer to: a DL resource interval that starts with a time / symbol that is earlier than a DL resource / slot with the same time index as the UL resource / slot (hereinafter referred to as the reference DL resource / slot) by a first (time) offset, and ends with a time / symbol that is later than the reference UL resource / slot by a second (time) offset. Here, for example, the first (time) offset and / or the second (time) offset can be values ​​that are (pre-)agreed and / or configured between the base station (or network) and the UE. Here, for example, the first (time) offset and / or the second (time) offset can include one or more elements, and one of these elements can include the (common) TA. Here, for example, the priority can follow the (pre-)agreed and / or (pre-)configured between the base station (or network) and the UE. Here, for example, the base station (or network) may (in advance) agree and / or configure / instruct the UE whether to perform the operation and / or which operation to perform.

[0173] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0174] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0175] Here, for example, due to reasons such as (UE)TA applications, in non-terrestrial networks, the base station (or network) and / or UE can identify DL resources / slots that conflict with (specific) UL resources / slots as a series of intervals. For example, the UE can deduce conflicting (potential) DL transmission intervals (hereinafter referred to as the first DL conflict interval) for configured and / or scheduled UL receive resources / slots (hereinafter referred to as the first UL transmission) (e.g., PUSCH) (assuming that the timing advance (TA) corresponds to a specific range). Here, for example, in order to support correct signal transmission / reception operation considering half-duplex transmission modes, it is necessary to pre-establish a mutual agreement between the base station (or network) and / or UE regarding the priority of transmissions between the first UL transmission and the first DL transmission (within the first DL conflict interval).

[0176] Therefore, in this disclosure, if there are at least one or more configured and / or scheduled DL receive resources / slots (hereinafter referred to as the first DL transmission) within the first DL conflict interval, the UE can determine the transmission to be prioritized between the first UL transmission and the first DL transmission (within the first DL conflict interval) in the following manner.

[0177] (1) If at least one or more first DL transmissions and / or all first DL transmissions have a higher priority than the first UL transmission, then the first DL transmissions (within the first DL conflict interval) may be performed first.

[0178] (2) In other cases, the first UL transmission can be prioritized.

[0179] Based on the proposed scheme of this disclosure, when the base station (or network) and the UE mutually identify potentially conflicting DL transmission intervals for (specific) UL transmissions by reflecting TA uncertainty in a non-terrestrial network, it has the advantage of being able to smoothly support the UE's half-duplex mode operation based on a clear protocol on which transmission, DL transmission or UL transmission interval, is prioritized.

[0180] The above-mentioned [Proposal #04] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0181] [Downlink reception priority]

[0182] [Proposal #05] In a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled DL receive resource / slot (hereinafter referred to as the first DL transmission) (e.g., PDSCH), the UE can deduce the (potential) UL transmission interval experiencing the conflict (hereinafter referred to as the first UL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled UL transmission resources / slots (hereinafter referred to as the first UL transmission) within the first UL conflict interval, the UE can perform one or more of the following actions.

[0183] (1) First operation

[0184] For example, for a (specific) first UL transmission (within the first UL conflict interval) having the earliest transmission time and / or scheduling time, if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of transmitting the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmission.

[0185] For example, if the above situation does not apply, the UE may not perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or expect to receive the first DL transmission.

[0186] (2) Second operation

[0187] For example, for at least one or more first UL transmissions (within the first UL conflict interval), if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of sending the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit (part and / or all) of the first UL transmissions (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmissions.

[0188] For example, if the above situation does not apply, the UE may not perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or expect to receive the first DL transmission.

[0189] (3) Third operation

[0190] For example, for all first UL transmissions (within the first UL conflict interval), if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of sending the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit (part and / or all) of the first UL transmissions (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmissions.

[0191] For example, if the above situation does not apply, the UE may not perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or expect to receive the first DL transmission.

[0192] (4) Fourth operation

[0193] For example, the UE may perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmission.

[0194] Here, for example, for a specific DL resource / slot, the conflicting (potential) UL transmission interval (assuming the TA corresponds to a specific range) can refer to: a UL resource interval with a start time of a time / symbol applied relative to a UL resource / slot with the same time index as the DL resource / slot (hereinafter referred to as the reference UL resource / slot), and an end time of a time / symbol applied relative to the reference UL resource / slot. Here, for example, the first (time) offset and / or the second (time) offset can be values ​​(pre-)agreed and / or configured between the base station (or network) and the UE. Here, for example, the first (time) offset and / or the second (time) offset can include one or more elements, and one of these elements can include the (common) TA. Here, for example, T_PROC,2 can refer to the processing time required for the UE to prepare for and / or cancel UL transmission. Here, for example, this operation can be an operation when the first DL transmission takes precedence over the first UL transmission (within the first UL conflict interval). Here, for example, the base station (or network) may (in advance) agree and / or configure / instruct the UE whether to perform the operation and / or which operation to perform.

[0195] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0196] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0197] Here, for example, due to reasons such as (UE)TA applications, in non-terrestrial networks, the base station (or network) and / or UE can identify UL resources / slots that conflict with (specific) DL resources / slots as a series of intervals. For example, the UE can deduce the (potential) UL transmission intervals that conflict with (specific) DL resources / slots (hereinafter referred to as the first DL transmission) (e.g., PDSCH) for configured and / or scheduled DL receive resources / slots (hereinafter referred to as the first DL transmission) (assuming that the timing advance (TA) corresponds to a specific range). Here, for example, depending on the characteristics of the message and / or scheduling type, there may be a situation where the first DL transmission takes precedence over the first UL transmission (within the first UL conflict interval).

[0198] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled DL receive resource / slot (hereinafter referred to as the first DL transmission) (e.g., PDSCH), the UE can deduce the (potential) UL transmission interval experiencing the conflict (hereinafter referred to as the first UL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled UL transmission resources / slots (hereinafter referred to as the first UL transmission) within the first UL conflict interval, the UE can perform one or more of the following operations.

[0199] (1) First operation

[0200] For example, for a (specific) first UL transmission (within the first UL conflict interval) having the earliest transmission time and / or scheduling time, if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of transmitting the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmission.

[0201] For example, if the above situation does not apply, the UE may not perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or expect to receive the first DL transmission.

[0202] (2) Second operation

[0203] For example, for at least one or more first UL transmissions (within the first UL conflict interval), if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of sending the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit (part and / or all) of the first UL transmissions (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmissions.

[0204] For example, if the above situation does not apply, the UE may not perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or expect to receive the first DL transmission.

[0205] (3) Third operation

[0206] For example, for all first UL transmissions (within the first UL conflict interval), if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of sending the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit (part and / or all) of the first UL transmissions (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmissions.

[0207] For example, if the above situation does not apply, the UE may not perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or expect to receive the first DL transmission.

[0209] For example, the UE may perform and / or expect to omit (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may perform and / or expect to receive the first DL transmission.

[0210] Based on the proposed scheme of this disclosure, when a base station (or network) and a UE in a non-terrestrial network derive potentially conflicting UL transmission intervals for a (specific) DL transmission by reflecting TA uncertainty and intending to prioritize that (specific) DL transmission, it has the advantage of being able to perform DL reception prioritization by taking into account the potentially conflicting UL transmission intervals and / or the processing time required for the UE to prepare / cancel the UL transmission (e.g., T_PROC,2). In this way, in the case of DL / UL conflict, the correct signal transmission / reception process can be performed between the base station (or network) and the UE based on the same understanding.

[0211] The above-mentioned [Proposal #05] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0212] [Proposal #06] In a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled UL transmission resource / slot (hereinafter referred to as the first UL transmission) (e.g., PUSCH), the UE can deduce the (potential) DL transmission interval experiencing the conflict (hereinafter referred to as the first DL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range).

[0215] For example, if not corresponding to the above situation, the UE may not perform and / or expect to omit the transmission for the first UL transmission, and / or the UE may not perform and / or expect to receive (part and / or all) of the first DL transmission (within the first DL conflict interval).

[0216] (2) Second operation

[0217] For example, for at least one or more first DL transmissions (within the first DL conflict interval), if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of sending the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit the UL transmission for the first UL transmission, and / or the UE may perform and / or expect to receive (part and / or all) of the first DL transmissions (within the first DL conflict interval).

[0218] For example, if not corresponding to the above situation, the UE may not perform and / or expect to omit the transmission for the first UL transmission, and / or the UE may not perform and / or expect to receive (part and / or all) of the first DL transmission (within the first DL conflict interval).

[0219] (3) Third operation

[0220] For example, for all first DL transmissions (within the first DL conflict interval), if the time interval between the end time / symbol of receiving configuration information and / or scheduling information for the first DL transmission (hereinafter referred to as the first time) and the start time / symbol of sending the first UL transmission (hereinafter referred to as the second time) is equal to or greater than / exceeds T_PROC,2, then the UE may perform and / or expect to omit the UL transmission for the first UL transmission, and / or the UE may perform and / or expect to receive (part and / or all) of the first DL transmissions (within the first DL conflict interval).

[0222] (4) Fourth operation

[0223] For example, the UE may perform and / or anticipate UL transmission omission for the first UL transmission, and the UE may perform and / or anticipate receiving (partial and / or all) of the first DL transmission (within the first DL conflict interval).

[0224] Here, for example, for a specific UL resource / slot, the conflicting (potential) DL transmission interval (assuming the TA corresponds to a specific range) can refer to: a DL resource interval that begins with a time / symbol that is earlier than a DL resource / slot with the same time index as the UL resource / slot (hereinafter referred to as the reference DL resource / slot) by a first (time) offset, and ends with a time / symbol that is later than the reference UL resource / slot by a second (time) offset.

[0241] The above-mentioned [Proposal #06] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0242] [Uplink transmission priority]

[0243] [Proposal #07] In a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled DL receive resource / slot (hereinafter referred to as the first DL transmission) (e.g., PDSCH), the UE can deduce the (potential) UL transmission interval experiencing the conflict (hereinafter referred to as the first UL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled UL transmission resources / slots (hereinafter referred to as the first UL transmission) within the first UL conflict interval, the UE can perform one or more of the following actions.

[0244] (1) First operation

[0245] For example, the UE may perform and / or anticipate (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or anticipate receiving the first DL transmission.

[0246] Here, for example, for a specific DL resource / slot, a conflicting (potential) UL transmission interval (assuming the TA corresponds to a specific range) can refer to: a UL resource interval with a start time of a time / symbol applied relative to a UL resource / slot having the same time index as the DL resource / slot (hereinafter referred to as the reference UL resource / slot), and an end time of a time / symbol applied relative to the reference UL resource / slot. Here, for example, the first (time) offset and / or the second (time) offset can be values ​​(pre-)agreed and / or configured between the base station (or network) and the UE. Here, for example, the first (time) offset and / or the second (time) offset can include one or more elements, and one of these elements can include the (common) TA. Here, for example, this operation can be an operation when a first UL transmission (within the first UL conflict interval) takes precedence over a first DL transmission. Here, for example, the base station (or network) can (pre-)agre and / or configure / instruct the UE whether to perform this operation and / or which operation to perform.

[0247] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0248] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0249] Here, for example, due to reasons such as (UE)TA applications, in non-terrestrial networks, the base station (or network) and / or UE can identify UL resources / slots that conflict with (specific) DL resources / slots as a series of intervals. For example, the UE can deduce the (potential) UL transmission intervals that conflict with (specific) DL resources / slots (hereinafter referred to as the first DL transmission) (e.g., PDSCH) for configured and / or scheduled DL receive resources / slots (hereinafter referred to as the first DL transmission) (assuming that the timing advance (TA) corresponds to a specific range). Here, for example, depending on the characteristics of the message and / or scheduling type, there may be a situation where the first UL transmission (within the first UL conflict interval) takes precedence over the first DL transmission.

[0250] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled DL receive resource / slot (hereinafter referred to as the first DL transmission) (e.g., PDSCH), the UE can deduce the (potential) UL transmission interval experiencing the conflict (hereinafter referred to as the first UL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled UL transmission resources / slots (hereinafter referred to as the first UL transmission) within the first UL conflict interval, the UE can perform one or more of the following operations.

[0251] (1) First operation

[0252] For example, the UE may perform and / or anticipate (part and / or all) of the first UL transmission (within the first UL conflict interval), and / or the UE may not perform and / or anticipate receiving the first DL transmission.

[0253] Based on the proposed scheme of this disclosure, when a base station (or network) and a UE in a non-terrestrial network derive potentially conflicting UL transmission intervals for (specific) DL transmissions by reflecting TA uncertainty, and intend to prioritize such UL transmission intervals, there is an advantage in being able to perform UL transmission prioritization by taking into account the potentially conflicting UL transmission intervals. In this way, in the event of DL / UL conflict, the correct signal transmission / reception process can be performed between the base station (or network) and the UE based on the same understanding.

[0254] The above-mentioned [Proposal #07] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0255] [Proposal #08] In a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled UL transmission resource / slot (hereinafter referred to as the first UL transmission) (e.g., PUSCH), the UE can deduce the (potential) DL transmission interval experiencing the conflict (hereinafter referred to as the first DL conflict interval) (assuming that the timing advance (TA) corresponds to a specific range). In this case, for example, if there are at least one or more configured and / or scheduled DL receive resources / slots (hereinafter referred to as the first DL transmission) within the first DL conflict interval, the UE can perform one or more of the following actions.

[0256] (1) First operation

[0257] For example, the UE may perform and / or anticipate the first UL transmission, and / or the UE may not perform and / or anticipate receiving (partial and / or all) of the first DL transmission (within the first DL conflict interval).

[0258] Here, for example, for a specific UL resource / slot, a conflicting (potential) DL transmission interval (assuming the TA corresponds to a specific range) can refer to a DL resource interval that begins with a time / symbol that is ahead of a first (time) offset compared to a DL resource / slot with the same time index as the UL resource / slot (hereinafter referred to as the reference DL resource / slot), and ends with a time / symbol that is behind the reference UL resource / slot by a second (time) offset. Here, for example, the first (time) offset and / or the second (time) offset can be values ​​that are (pre-)agreed and / or configured between the base station (or network) and the UE. Here, for example, the first (time) offset and / or the second (time) offset can include one or more elements, and one of these elements can include a (common) TA. Here, for example, this operation can be an operation when a first UL transmission takes precedence over a first DL transmission (within the first DL conflict interval). Here, for example, the base station (or network) can (pre-)agreed and / or configured / indicated to the UE whether to perform this operation and / or which operation to perform.

[0259] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0260] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0261] Here, for example, due to reasons such as (UE)TA applications, in non-terrestrial networks, the base station (or network) and / or UE can identify DL resources / slots that conflict with (specific) UL resources / slots as a series of intervals. For example, the UE can deduce the (potential) DL transmission intervals that conflict with (specific) UL resources / slots (hereinafter referred to as the first UL transmission) (e.g., PUSCH) for configured and / or scheduled UL receive resources / slots (hereinafter referred to as the first UL transmission) (assuming that the timing advance (TA) corresponds to a specific range). Here, for example, depending on the characteristics of the message and / or scheduling type, there may be a situation where the first UL transmission takes precedence over the first DL transmission (within the first DL conflict interval).

[0262] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to a half-duplex transmission mode, then for a configured and / or scheduled UL transmission resource / slot (hereinafter referred to as a first UL transmission) (e.g., PUSCH), the UE can deduce the (potential) DL transmission interval experiencing the conflict (hereinafter referred to as a first DL conflict interval) (assuming that timing advance (TA) corresponds to a specific range). In this case, for example, if at least one or more configured and / or scheduled DL reception resources / slots (hereinafter referred to as first DL transmissions) exist within the first DL conflict interval, the UE can perform one or more of the following actions.

[0263] (1) First operation

[0264] For example, the UE may perform and / or anticipate the first UL transmission, and / or the UE may not perform and / or anticipate receiving (partial and / or all) of the first DL transmission (within the first DL conflict interval).

[0265] Based on the proposed scheme of this disclosure, when a base station (or network) and a UE in a non-terrestrial network derive potentially conflicting DL transmission intervals for a (specific) UL transmission by reflecting TA uncertainty, and intend to prioritize such UL transmissions, there is an advantage in being able to perform UL transmission prioritization by taking into account the potentially conflicting DL transmission intervals. In this way, in the event of DL / UL conflict, the correct signal transmission / reception process can be performed between the base station (or network) and the UE based on the same understanding.

[0266] The above-mentioned [Proposal #08] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0267] [Exception Handling Operation]

[0268] [Proposal #09] In non-terrestrial networks, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to half-duplex transmission mode, the base station (or network) can configure / indicate the (expected) TA range (hereinafter referred to as the first TA range) to the UE. In this case, the UE can apply different DL / UL conflict handling rules for cases where its self-calculated TA (hereinafter referred to as the second TA) exists within the first TA range and cases where it does not exist within the first TA range. For example, if data to be transmitted in the buffer is generated and / or if transmission is scheduled, the UE can calculate the TA. For example, the UE can apply DL / UL conflict handling rules as follows.

[0269] (1) When the second TA exists within the range of the first TA

[0270] DL / UL conflicting resources are determined based on the first TA range and conflict handling rules are applied.

[0271] (2) When the second TA does not exist within the range of the first TA

[0272] Option 1: Determine DL / UL conflicting resources based on the second TA and apply conflict handling rules.

[0273] Option B. Option 2: Omit the transfer of UL resources (dynamically scheduled and / or semi-statically configured).

[0274] Here, for example, a (specific) uplink physical channel / resource that is (pre-)agreed / configured between the base station (or network) and the UE can be excluded from the target of UL transmission omission. Here, for example, the base station (or network) can (pre-)agre and / or configure / instruct the UE whether to perform this operation and / or which operation to perform.

[0275] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0276] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0277] Here, for example, in a non-terrestrial network, the base station (or network) and the UE (in advance) agree and / or configure a mutual (expected) TA range (hereinafter referred to as the first TA range), and when executing DL / UL conflict handling rules according to the half-duplex transmission mode, the determination of DL / UL conflict resources and conflict handling rules can be applied based on the first TA range. Here, for example, if the actual TA calculated by the UE (hereinafter referred to as the second TA) deviates from the first TA range, there may be a situation where the determination of DL / UL conflict resources between the base station (or network) and the UE differs from each other. In the above case, the UE may omit UL transmission (until TA is reported), or it may determine whether to transmit UL after determining the DL / UL conflict resources based on its own second TA in a best-effort (BE) manner.

[0278] Based on the proposed scheme of this disclosure, when the base station (or network) and UE apply DL / UL conflict handling rules based on the TA range to reflect TA uncertainty in a non-terrestrial network, it can support abnormal handling of UE operation when the actual TA deviates from the TA range. This approach has the advantage of being able to clearly define UE operation under abnormal circumstances.

[0279] The above-mentioned [Proposal #09] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0280] [Proposal #10] In a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to half-duplex transmission mode, the base station (or network) can configure / indicate a (predicted) TA range (hereinafter referred to as the first TA range) to the UE. In this case, for example, if the TA calculated by the UE itself (hereinafter referred to as the second TA) deviates from this TA range, the UE can perform one or more of the following actions.

[0281] (1) TA mismatch event report

[0282] (2) SR transmission for TA reports

[0283] (3) TA report trigger and / or TA report

[0284] Here, for example, the base station (or network) may (pre-)agree and / or configure / instruct the UE whether to perform the operation. Here, for example, a TA mismatch event report may include a report of an event in which the second TA deviates from the range of the first TA.

[0285] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0286] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0287] Here, for example, in a non-terrestrial network, the base station (or network) may (pre-)agree and / or configure / indicate (expected) TA range information (hereinafter referred to as the first TA range) to a UE operating in half-duplex mode. Here, for example, the base station (or network) and / or the UE may assume that the first TA range identifies (potential) DL / UL conflicting resources in the same way. Here, for example, if the TA calculated by the UE (hereinafter referred to as the second TA) deviates from the first TA range configured / indicated by the base station (or network), the method of identifying DL / UL conflicting resources between the base station (or network) and the UE based on the first TA range may no longer be effective. Here, for example, the UE may need to report the above situation to the base station (or network) quickly. For example, the UE may report the event itself, or it may naturally perform SR transmission and / or TA report triggering and / or TA report operations for TA reporting based on the occurrence of the event.

[0288] Based on the proposed scheme of this disclosure, when the base station (or network) and UE manage DL / UL conflicting resources based on the (expected) TA range by reflecting TA uncertainty in a non-terrestrial network, it has the advantage of supporting rapid situation identification on the base station (or network) side when the UE's actual TA deviates from the (expected) TA range. In this way, the base station (or network) updates the (expected) TA range again so that the base station (or network) and UE can equally understand the (potential) DL / UL conflicting resources, thereby supporting the corresponding execution of the correct transmission / reception procedures.

[0289] The above-mentioned [Proposal #10] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0290] [Proposal #11] In non-terrestrial networks, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to half-duplex transmission mode, and if a conflict occurs between a dynamically scheduled transmission (hereinafter referred to as the first transmission) and a semi-statically configured transmission (hereinafter referred to as the second transmission), the priority between the first transmission and the second transmission can be applied differently based on the order between the scheduling for the first transmission and the activation configuration / indication / time for the second transmission. For example, the UE can apply the priority as follows.

[0291] (1) If activation for the second transmission is configured / indicated / started before scheduling for the first transmission, the first transmission / reception may be prioritized.

[0292] (2) If activation for the second transmission is configured / indicated / started after scheduling for the first transmission, the second transmission / reception may be prioritized.

[0293] Here, for example, the base station (or network) may (pre-)agree and / or configure / instruct the UE whether to perform the operation. Here, for example, the base station (or network) may (pre-)agree and / or (pre-)configure priority information to be applied to the UE between the first and second transmissions according to the order between scheduling for the first transmission and activation triggering for the second transmission. Here, for example, the first and second transmissions may be DL transmission and UL transmission, respectively, or UL transmission and DL transmission, respectively.

[0294] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0295] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the (common) TA and / or (UE) TA can have very large values. For example, in the case of LEO satellites, considering the round-trip time (RTT) delay corresponding to approximately tens of milliseconds, the overall TA size can correspond to approximately tens of time slots. Here, the base station (or network) can consider the additional timing offset (hereinafter referred to as K_offset) configured during uplink scheduling.

[0296] Here, for example, according to the traditional DL / UL conflict handling rules for half-duplex transmission mode, dynamically scheduled transmission resources (hereinafter referred to as the first transmission resource) may take precedence over semi-statically configured transmission resources (hereinafter referred to as the second transmission resource). Here, for example, the DL / UL conflict handling rules may be based on the assumption that the base station (or network) is aware of the existence of the semi-statically configured second transmission resource. Here, for example, considering that the uplink scheduling timing (e.g., K_offset) in non-terrestrial networks may be very long, unlike the traditional case, activation of the second transmission resource can be configured / indicated after the first transmission resource is dynamically scheduled.

[0297] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to the half-duplex transmission mode, if a conflict occurs between a dynamically scheduled UL transmission (hereinafter referred to as the first UL transmission) and a semi-statically configured DL transmission (hereinafter referred to as the first DL transmission), the priority between the first UL transmission and the first DL transmission can be applied differently according to the order of scheduling for the first UL transmission and activation triggering for the first DL transmission. For example, if activation for the first DL transmission is configured / indicated before scheduling for the first UL transmission, the UE can prioritize the first UL transmission; and if activation for the first DL transmission is configured / indicated after scheduling for the first UL transmission, the UE can prioritize the first DL transmission.

[0298] Based on the proposed scheme of this disclosure, the conflict handling rules between dynamically scheduled transmissions and semi-statically configured transmissions can be defined by considering the relatively long uplink scheduling time in non-terrestrial networks. Specifically, by comparing the scheduling time with the activation time of semi-statically configured resources, it has the advantage of prioritizing the transmissions expected / intended by the base station (or network).

[0299] The above-mentioned [Proposal #11] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0300] [Proposal #12] In non-terrestrial networks, if the base station (or network) and / or UE can execute DL / UL conflict handling rules according to half-duplex transmission mode, for UL transmissions (e.g., PUSCH and / or PUCCH) applying demodulation reference signal (DM-RS) bundling and / or time-domain window (TDW), the base station (or network) can agree / configure / instruct the UE that the UL transmission takes precedence over another (specific) DL reception, or agree / configure / instruct that (specific) DL reception is not performed during the UL transmission. Here, for example, SSB reception can be excluded from (specific) DL reception. Here, for example, DM-RS bundling can refer to the operation of performing channel estimation using DM-RS resources between repeated UL transmissions. Here, for example, TDW can refer to the (time) interval by which the UE guarantees phase continuity and / or power consistency.

[0301] For example, in a non-terrestrial network according to an embodiment of this disclosure, it is assumed that a base station (or network) provides services to a UE operating in half-duplex transmission mode based on the non-terrestrial network. Here, for example, if the UE operates in half-duplex transmission mode, it cannot simultaneously perform DL reception and UL transmission, and if the DL reception time and UL transmission time conflict, the UE can prioritize performing DL reception and / or UL transmission based on DL / UL conflict handling rules pre-agreed / configured with the base station, or it can determine this as an error condition based on the UE implementation.

[0302] Here, for example, in the uplink of a non-terrestrial network, the UE can apply a (common) timing advance (TA) to compensate for the time delay between the feed link and the satellite, and a (UE) TA to compensate for the time delay between the UE and the satellite. Here, for example, the (common) TA is a value mutually recognized by both the base station (or network) and the UE through parameters and calculation formulas shared between them, and the (UE) TA can be a value that is autonomously adjusted by the UE and unknown on the base station (or network) side. Here, for example, the TA expected / predicted by the base station (or network) for the UE (first TA) and the TA actually applied by the UE (second TA) can have different values, and this may lead to different mutual recognition of DL / UL conflicting resources.

[0303] Here, for example, considering the extensive coverage area of ​​non-terrestrial networks, the UE can support DM-RS bundling, which utilizes DM-RS resources between repeated transmissions during uplink transmissions to perform joint channel estimation processing over the entire repeated transmission. Here, for example, the UE can support Time Domain Window (TDW), which is an interval that guarantees phase continuity and / or power consistency from the signal transmission perspective. Here, for example, if the UE receives DL (Low-Low) transmissions within an uplink transmission interval, phase continuity and / or power consistency may not be maintained, and therefore the (actual) TDW may end at the point of conflict between UL transmission and DL reception. Here, for example, due to reasons such as (UE) TA (Temporal Aspect Ratio), in non-terrestrial networks, the base station (or network) may not accurately identify the time of conflict between UL transmission and DL reception from the UE's perspective, and as a result, the identification of the (actual) TDW interval between the base station (or network) and the UE may differ. In the above cases, because the base station (or network) performs joint channel estimation using DM-RS within an incorrect interval, uplink reception performance may degrade.

[0304] Therefore, in this disclosure, in a non-terrestrial network, if the base station (or network) and / or UE are able to execute DL / UL conflict handling rules according to the half-duplex transmission mode, for UL transmissions (e.g., PUSCH and / or PUCCH) with DM-RS bundling and / or time-domain window (TDW) applied, the base station (or network) may agree / configure / instruct the UE that the UL transmission takes precedence over another (specific) DL reception, or agree / configure / instruct that (specific) DL reception is not performed during the UL transmission.

[0305] Based on the proposed scheme of this disclosure, for UL transmissions that employ DM-RS bundling and / or TDW, TDW segmentation can be prevented as much as possible, thereby preventing the base station (or network) from incorrectly identifying the (actual) TDW interval in the UE as much as possible.

[0306] The above-mentioned [Proposal #12] can be combined with other proposals to the extent that the proposed operations do not conflict.

[0307] Figure 13 A method for a device to perform wireless communication based on an embodiment of the present disclosure is shown. Figure 13 The implementation methods can be combined with various implementation methods of this disclosure.

[0308] Reference Figure 13 In step S1310, the device may acquire information related to the first offset. In step S1320, the device may acquire information related to the second offset. In step S1330, the device may receive information related to transmission resources. In step S1340, the device may determine the transmission interval that conflicts with the transmission resources. For example, the transmission interval may start before the first offset and end after the second offset relative to a reference resource associated with the transmission resources.

[0309] In addition, for example, the device can receive information about whether the transmission resource is a priority resource.

[0310] For example, a transmission resource can be a resource used for downlink transmission. For example, a reference resource can be a resource for uplink transmission with the same time index as the transmission resource. For example, based on the fact that at least one uplink transmission within a transmission interval has a higher priority than a downlink transmission, uplink transmission may take precedence over downlink transmission within the transmission interval. For example, based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between the reception of configuration information or scheduling information for downlink transmission and the earliest uplink transmission within the transmission interval is greater than or equal to the processing time, uplink transmission may be omitted within the transmission interval. For example, based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between the reception of configuration information or scheduling information for downlink transmission and the earliest uplink transmission within the transmission interval is less than the processing time, uplink transmission may be performed within the transmission interval.

[0311] For example, a transmission resource can be a resource used for uplink transmission. For example, a reference resource can be a resource for downlink transmission with the same time index as the transmission resource. For example, downlink transmission may take precedence over uplink transmission within a transmission interval based on the higher priority of at least one downlink transmission within the transmission interval. For example, uplink transmission may be omitted within a transmission interval based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between receiving configuration or scheduling information for uplink transmission and the earliest downlink transmission within the transmission interval being greater than or equal to the processing time. For example, uplink transmission may be performed within a transmission interval based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between receiving configuration or scheduling information for uplink transmission and the earliest downlink transmission within the transmission interval being less than the processing time.

[0312] Furthermore, for example, the device can receive information related to the timing advance range. Furthermore, for example, the device can determine the timing advance. For example, priority rules for uplink and downlink conflicts can be applied differently based on whether the timing advance is within the timing advance range. For example, if a default priority rule is defined, if the timing advance is outside the timing advance range, the configured priority rule can be released, and the default priority rule can be applied automatically. For example, if a default priority rule is defined, if the timing advance is within the timing advance range, the configured priority rule can be applied. For example, based on the timing advance being within the timing advance range, it is possible to determine whether a conflict has occurred between the uplink and downlink. For example, based on the timing advance being outside the timing advance range, it is possible to determine whether a conflict has occurred between the uplink and downlink.

[0313] The proposed method can be applied to apparatuses based on various embodiments of this disclosure. First, the processor 102 of apparatus 100 can acquire information related to a first offset. Furthermore, the processor 102 of apparatus 100 can acquire information related to a second offset. Additionally, the processor 102 of apparatus 100 can control the transceiver 106 to receive information related to transmission resources. Furthermore, the processor 102 of apparatus 100 can determine transmission intervals that conflict with transmission resources. For example, the transmission interval may begin before the first offset and end after the second offset relative to a reference resource associated with the transmission resource.

[0314] Based on embodiments of this disclosure, an apparatus can be provided. For example, the apparatus may include: at least one transceiver; at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on instructions executed by the at least one processor, the apparatus may perform operations including: acquiring information related to a first offset; acquiring information related to a second offset; receiving information related to transmission resources; and determining a transmission interval that conflicts with the transmission resources. For example, the transmission interval may begin before the first offset and end after the second offset relative to a reference resource associated with the transmission resources.

[0315] Based on embodiments of this disclosure, a processing apparatus adapted as a control device can be provided. For example, the processing apparatus may include: at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, based on instructions executed by the at least one processor, the apparatus may perform operations including: acquiring information related to a first offset; acquiring information related to a second offset; receiving information related to a transmission resource; and determining a transmission interval that conflicts with the transmission resource. For example, the transmission interval may begin before the first offset and end after the second offset relative to a reference resource associated with the transmission resource.

[0316] Based on embodiments of this disclosure, a non-transitory computer-readable storage medium for storing instructions can be provided. For example, when the instructions are executed, the apparatus can perform operations including: acquiring information related to a first offset; acquiring information related to a second offset; receiving information related to a transmission resource; and determining a transmission interval that conflicts with the transmission resource. For example, the transmission interval may begin before the first offset and end after the second offset relative to a reference resource associated with the transmission resource.

[0317] Figure 14 A method for performing wireless communication for a base station based on an embodiment of the present disclosure is shown. Figure 14 The implementation methods can be combined with various implementation methods of this disclosure.

[0318] Reference Figure 14 In step S1410, the base station can acquire information related to the first offset. In step S1420, the base station can acquire information related to the second offset. In step S1430, the base station can transmit information related to transmission resources. In step S1440, the base station can determine the transmission interval that conflicts with the transmission resources. For example, the transmission interval can start before the first offset and end after the second offset relative to a reference resource related to the transmission resources.

[0319] In addition, for example, the base station can transmit information about whether the transmission resource is a priority resource.

[0320] For example, a transmission resource can be a resource used for downlink transmission. For example, a reference resource can be a resource for uplink transmission with the same time index as the transmission resource. For example, based on the fact that at least one uplink transmission within a transmission interval has a higher priority than a downlink transmission, uplink transmission may take precedence over downlink transmission within the transmission interval. For example, based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between the reception of configuration information or scheduling information for downlink transmission and the earliest uplink transmission within the transmission interval is greater than or equal to the processing time, uplink transmission may be omitted within the transmission interval. For example, based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between the reception of configuration information or scheduling information for downlink transmission and the earliest uplink transmission within the transmission interval is less than the processing time, uplink transmission may be performed within the transmission interval.

[0321] For example, a transmission resource can be a resource used for uplink transmission. For example, a reference resource can be a resource for downlink transmission with the same time index as the transmission resource. For example, downlink transmission may take precedence over uplink transmission within a transmission interval based on the higher priority of at least one downlink transmission within the transmission interval. For example, uplink transmission may be omitted within a transmission interval based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between receiving configuration or scheduling information for uplink transmission and the earliest downlink transmission within the transmission interval being greater than or equal to the processing time. For example, uplink transmission may be performed within a transmission interval based on (i) downlink transmission taking precedence over uplink transmission, and (ii) the time interval between receiving configuration or scheduling information for uplink transmission and the earliest downlink transmission within the transmission interval being less than the processing time.

[0322] Furthermore, for example, the base station can transmit information related to the timing advance range. For example, priority rules for uplink and downlink conflicts can be applied differently based on whether the timing advance determined by the device is within the timing advance range. For example, if a default priority rule is defined, if the timing advance is outside the timing advance range, the configured priority rule can be released, and the default priority rule can be applied automatically. For example, if a default priority rule is defined, if the timing advance is within the timing advance range, the configured priority rule can be applied. For example, based on the timing advance determined by the device being within the timing advance range, it is possible to determine whether a conflict has occurred between the uplink and downlink based on the timing advance range. For example, based on the timing advance determined by the device being outside the timing advance range, it is possible to determine whether a conflict has occurred between the uplink and downlink based on the timing advance.

[0323] The proposed method can be applied to an apparatus based on various embodiments of this disclosure. First, the processor 202 of the base station 200 can acquire information related to a first offset. Furthermore, the processor 202 of the base station 200 can acquire information related to a second offset. Additionally, the processor 202 of the base station 200 can control the transceiver 206 to transmit information related to transmission resources. Furthermore, the processor 202 of the base station 200 can determine transmission intervals that conflict with transmission resources. For example, the transmission interval can begin before the first offset and end after the second offset relative to a reference resource associated with the transmission resource.

For example, the base station may include: at least one transceiver; at least one processor; and at least one memory connected to the at least one processor and storing instructions. For example, the instructions, based on execution by the at least one processor, can cause the base station to perform operations including: acquiring information related to a first offset; acquiring information related to a second offset; transmitting information related to transmission resources; and determining a transmission interval that conflicts with the transmission resources.

For example, the transmission interval may begin before the first offset and end after the second offset relative to a reference resource related to the transmission resources.

[0326] Based on embodiments of this disclosure, a non-transitory computer-readable storage medium storing instructions can be provided. For example, when executed, the instructions can cause a base station to perform operations including: acquiring information related to a first offset; acquiring information related to a second offset; transmitting information related to transmission resources; and determining a transmission interval that conflicts with the transmission resources. For example, the transmission interval may begin before the first offset and end after the second offset relative to a reference resource related to the transmission resources.

[0345] Figure 17 A signal processing circuit for transmitting signals based on an embodiment of the present disclosure is shown. Figure 17 The implementation methods can be combined with various implementation methods of this disclosure.

[0346] Reference Figure 17 The signal processing circuit 1000 may include a scrambler 1010, a modulator 1020, a layer mapper 1030, a pre-encoder 1040, a resource mapper 1050, and a signal generator 1060. It can perform... Figure 17 Operations / functions, but not limited to Figure 16Processors 102 and 202 and / or transceivers 106 and 206. Figure 17 The hardware components can be used Figure 16 The processors 102 and 202 and / or transceivers 106 and 206 are used for implementation. For example, boxes 1010 to 1060 can be implemented using... Figure 16 Processors 102 and 202 are used for implementation. Alternatively, blocks 1010 to 1050 can be implemented using... Figure 16 The processors 102 and 202 are used to implement this, and the box 1060 can be implemented through... Figure 16 This is achieved using transceivers 106 and 206.

[0347] Typing can be done through Figure 17 The signal processing circuit 1000 converts the signal into a radio signal. In this document, a codeword is a sequence of encoded bits for an information block. An information block may include a transport block (e.g., a UL-SCH transport block, a DL-SCH transport block). Radio signals can be transmitted through various physical channels (e.g., PUSCH and PDSCH).

[0348] Specifically, the codeword can be converted into a scrambled bit sequence by scrambler 1010. The scrambling sequence used for scrambling can be generated based on an initialization value, which may include the ID information of the wireless device. The scrambling bit sequence can be modulated into a modulation symbol sequence by modulator 1020. The modulation scheme may include pi / 2-binary phase shift keying (pi / 2-BPSK), m-phase shift keying (m-PSK), and m-quadrature amplitude modulation (m-QAM). The complex modulation symbol sequence can be mapped to one or more transmission layers by layer mapper 1030. The modulation symbols of each transmission layer can be mapped (pre-encoded) to the corresponding antenna port by pre-encoder 1040. The output z of pre-encoder 1040 can be obtained by combining the output y of layer mapper 1030 with N... The M precoding matrix W is obtained by multiplying the M precoding matrix. In this paper, N is the number of antenna ports and M is the number of transmission layers. The precoder 1040 can perform precoding after performing transform precoding (e.g., DFT) on the complex modulation symbols. Alternatively, the precoder 1040 can perform precoding without performing transform precoding.

[0349] Resource mapper 1050 maps modulation symbols for each antenna port to time-frequency resources. Time-frequency resources may include multiple symbols in the time domain (e.g., CP-OFDMA symbols and DFT-s-OFDMA symbols) and multiple subcarriers in the frequency domain. Signal generator 1060 can generate radio signals from the mapped modulation symbols, and the generated radio signals can be transmitted to other devices via each antenna. For this purpose, signal generator 1060 may include an inverse fast Fourier transform (IFFT) module, a cyclic prefix (CP) inserter, a digital-to-analog converter (DAC), and a frequency up-converter.

[0350] The signal processing procedure used for signals received in a wireless device can be compared with... Figure 17 The signal processing procedures 1010 to 1060 are configured in the reverse manner. For example, wireless devices (e.g., Figure 16 The receiver (100 and 200) can receive radio signals from the outside via the antenna port / transceiver. The received radio signals can be converted into baseband signals by a signal restorer. For this purpose, the signal restorer may include a frequency down-converter, an analog-to-digital converter (ADC), a CP remover, and a Fast Fourier Transform (FFT) module. Next, the baseband signal can be recovered into codewords through a resource demapping process, a post-encoding process, a demodulation processor, and a descrambling process. The codewords can be recovered into the original information blocks through decoding. Therefore, the signal processing circuitry (not illustrated) for receiving signals may include a signal restorer, a resource demapping unit, a post-encoder, a demodulator, a descrambler, and a decoder.

Each element, component, unit / part, and / or module within wireless devices 100 and 200 may also include one or more elements. For example, control unit 120 may be configured by a collection of one or more processors.
