[0036] FIG. 1 illustrates a device-to-device communication procedure according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0037] Referring to FIG. 1, in step S101, a first device and a second device can perform synchronization. For example, the first device can be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device can be a base station, a network, a RAN node, an NTN node / cell, a TRP, a terminal and / or at least one of the devices proposed in the present disclosure. For example, the first device can perform an initial cell search operation. For example, the first device can detect at least one synchronization signal transmitted by the second device according to a predefined rule. Here, for example, the synchronization signal can include a plurality of synchronization signals classified according to a structure or purpose (e.g., a primary synchronization signal, a secondary synchronization signal, etc.). Through this, the first device can identify the boundaries of the frame, subframe, time unit, slot, and / or symbol of the second device, and the first device can obtain information about the second device (e.g., a cell identifier).

[0038] In step S103, the first device can obtain system information transmitted by the second device. For example, the system information may include information related to the properties, characteristics, and / or capabilities of the second device required to connect to the second device and use the service. For example, the system information may be classified according to content (e.g., whether it is essential for connection), transmission structure (e.g., channel used, whether provided on-demand), etc. For example, the system information may be classified into a master information block (MIB) and a system information block (SIB). For example, if necessary, the first device may transmit a signal requesting system information prior to receiving the system information. For example, the request and provision of system information may be performed after a random access procedure described below.

[0039] In step S105, the first device and the second device can perform a random access procedure. For example, the first device can transmit and / or receive at least one message (e.g., a random access preamble, a random access response message, etc.) for the random access procedure based on information related to a random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device can transmit a preamble (e.g., Msg1) through the random access channel, the first device can receive a random access response message (e.g., Msg2), the first device can transmit a message (e.g., Msg3) including information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device can receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be sent and received as one message (e.g., MsgA), and / or Msg2 and Msg4 can be sent and received as one message (e.g., MsgB).

[0040] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer that controls a connection (e.g., a radio resource control (RRC) layer), a layer that handles mapping between logical channels and transport channels (e.g., a media access control (MAC) layer), a layer that handles physical channels (e.g., a physical (PHY) layer), etc. For example, the first device and the second device may perform at least one of signaling for establishing a connection, signaling for determining settings related to communication, and / or signaling for indicating allocated resources. For example, the control information may be signaled / transmitted via a control channel. For example, the control information and / or the control channel may be used to schedule at least one of data, a data channel (e.g., a shared channel), and / or control information on the data channel.

[0041] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process, transmit, and / or receive data based on signaling of control information. For example, when transmitting data, the first device or the second device may perform at least one of channel encoding, rate matching, scrambling, constellation mapping, layer mapping, waveform modulation, antenna mapping, and / or resource mapping on the information bits. For example, when receiving data, the first device or the second device may perform at least one of signal extraction from resources, waveform demodulation for each antenna, signal arrangement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0042] For example, the layers of a radio interface protocol between a first device and a second device can be divided into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, a physical layer belonging to the first layer can provide an information transfer service using a physical channel, and an RRC (radio resource control) layer located in the third layer can play a role in controlling radio resources between the first device and the second device. For this purpose, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0043] FIG. 2 illustrates a radio protocol architecture according to an embodiment of the present disclosure. The embodiment of FIG. 2 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. For example, (a) of FIG. 2 may illustrate a radio protocol stack of a user plane for uplink communication or downlink communication, and (b) of FIG. 2 may illustrate a radio protocol stack of a control plane for uplink communication or downlink communication. For example, (c) of FIG. 2 may illustrate a radio protocol stack of a user plane for device-to-device communication, and (d) of FIG. 2 may illustrate a radio protocol stack of a control plane for device-to-device communication.

[0044] For example, the physical layer can provide information transmission services to upper layers using physical channels. For example, the physical layer can be connected to the upper layer, the medium access control (MAC) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through the transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted over the wireless interface. For example, data can be transmitted between different physical layers, for example, between the physical layers of a first device and a second device, through a physical channel. For example, the physical channel can be modulated using an orthogonal frequency division multiplexing (OFDM) scheme, and time and frequency can be utilized as radio resources.

[0045] For example, the MAC layer can provide services to the upper layer, the radio link control (RLC) layer, through logical channels. For example, the MAC layer can provide a mapping function from multiple logical channels to multiple transport channels. For example, the MAC layer can provide a logical channel multiplexing function by mapping multiple logical channels to a single transport channel. For example, the MAC sublayer can provide data transmission services on logical channels.

[0046] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee the various quality of service (QoS) required by radio bearers (RBs), the RLC layer can provide three operating modes: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat request (ARQ).

[0047] For example, the RRC (radio resource control) layer can be defined only in the control plane. For example, the RRC layer can be responsible for controlling logical channels, transport channels, and physical channels in relation to the configuration, re-configuration, and release of radio bearers. For example, an RB can mean a logical path provided by a first layer (e.g., a physical layer) and a second layer (e.g., a MAC layer, an RLC layer, a PDCP (packet data convergence protocol) layer, a SDAP (service data adaptation protocol) layer, etc.) for data transmission between a first device and a second device.

[0048] For example, the functions of the PDCP layer in the user plane may include forwarding of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include forwarding of control plane data and ciphering / integrity protection.

[0049] For example, establishing an RB can refer to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. For example, RBs can be divided into two types: signaling radio bearers (SRBs) and data radio bearers (DRBs). For example, SRBs can be used as a channel to transmit RRC messages in the control plane, while DRBs can be used as a channel to transmit user data in the user plane.

[0050] For example, a downlink transmission channel may include at least one of a broadcast channel (BCH) for transmitting system information, and / or a downlink shared channel (SCH) for transmitting user traffic or control messages. For example, traffic or control messages of a downlink multicast or broadcast service may be transmitted through the downlink SCH, or may be transmitted through a separate downlink multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) for transmitting initial control messages, and / or an uplink shared channel (SCH) for transmitting user traffic or control messages. For example, a logical channel located above a transmission channel and mapped to the transmission channel may include at least one of a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and / or a multicast traffic channel (MTCH).

[0051] FIG. 3 illustrates the structure of a wireless frame according to an embodiment of the present disclosure. The embodiment of FIG. 3 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0052] Referring to FIG. 3, for example, a radio frame may be used in uplink transmission, downlink transmission, and / or device-to-device transmission. For example, a radio frame may have a length of 10 ms and may be defined as two 5 ms half-frames (HF). For example, a half-frame may include five 1 ms subframes (SF). For example, a subframe may be divided into one or more slots, and the number of slots within a subframe may be determined according to a subcarrier spacing (SCS). For example, each slot may include 12 or 14 OFDM (A) symbols, depending on a cyclic prefix (CP).

[0053] For example, when normal CP is used, each slot can contain 14 symbols. For example, when extended CP is used, each slot can contain 12 symbols. Here, for example, the symbols can contain OFDM symbols (or CP-OFDM symbols), SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0054] Table 2 below shows the number of symbols per slot (N) depending on the SCS setting (u) when normal CP or extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot) is an example.

[0055] CP type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slot Normal CP15kHz (u=0)1410130kHz (u=1)1420260kHz (u=2)14404120kHz (u=3)14808240kHz (u=4)1416016Extended CP60kHz (u=2)12404

[0056] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single terminal. Accordingly, the (absolute time) interval of time resources (e.g., subframes, slots, or transmit time intervals (TTIs)) composed of the same number of symbols may be set differently between the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTIs, etc. may be referred to as time units.

[0057] For example, multiple numerologies, or SCSs, may be supported to support various services. For example, a 15 kHz SCS may support wide areas in traditional cellular bands, while a 30 kHz / 60 kHz SCS may support dense urban areas, lower latency, and wider carrier bandwidth. For example, a 60 kHz or higher SCS may support bandwidths greater than 24.25 GHz to overcome phase noise.

[0058] FIG. 4 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 4 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0059] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain, and may correspond to one numerology (e.g., SCS, CP length, etc.). For example, a carrier may include at most N BWPs (where N is a positive integer). For example, data communication may be performed through an activated BWP. For example, each element may be referred to as a resource element (RE) in the resource grid, and one complex symbol may be mapped to it.

[0060] For example, a BWP may be a contiguous set of PRBs in a given numerology. For example, a PRB may be selected from a contiguous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0061] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the UE may not monitor the downlink radio link quality in a DL BWP other than the active DL BWP on the PCell (primary cell). For example, the UE may not receive a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), or a channel state information-reference signal (CSI-RS) (except for radio resource management (RRM)) outside of the active DL BWP. For example, the UE may not trigger channel state information (CSI) reporting for an inactive DL BWP. For example, the UE may not transmit a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) outside of the active UL BWP. For example, for downlink, the initial BWP can be given as a set of consecutive resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For uplink, for example, the initial BWP can be given by the system information block (SIB) for the random access procedure. For example, the default BWP can be set by a higher layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if a terminal does not detect DCI (downlink control information) for a certain period of time, the terminal may switch its active BWP to a default BWP.

[0062] FIG. 5 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 5 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0063] Referring to FIG. 5, for example, a common resource block (CRB) may be a carrier resource block numbered from one end of a carrier band to the other, and a PRB may be a numbered resource block within each BWP. For example, point A may indicate a common reference point for a resource block grid.

[0064] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWP ) can be set by. For example, point A can be an outer reference point of the PRB of a carrier where subcarrier 0 of all numerologies (e.g., all numerologies supported by the network on that carrier) aligns. For example, the offset can be the PRB spacing between the lowest subcarrier in a given numerology and point A. For example, the bandwidth can be the number of PRBs in a given numerology.

[0065] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to an embodiment of the present disclosure. The embodiment of FIG. 6 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0066] As core implementation technologies of the 6G system, technologies such as artificial intelligence (AI), THz (terahertz) communication, optical wireless technology, free-space optical transmission (FSO) backhaul networks, massive MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0067] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. For example, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a crucial role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. AI can also facilitate rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0068] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by using sub-THz communication with wide bandwidths and applying advanced massive MIMO technology. THz waves, also known as sub-millimeter waves, typically refer to the frequency range between 0.1 THz and 10 THz, with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz to 300 GHz band (sub-THz band) is considered a key part of the THz spectrum for cellular communications. Adding the sub-THz band to the mmWave band will increase the capacity of 6G cellular communications. Among the defined THz bands, 300 GHz to 3 THz lies in the far infrared (IR) frequency band. While part of the optical band, the 300 GHz to 3 THz band lies at the boundary of the optical band, immediately following the RF band. Therefore, this 300 GHz to 3 THz band exhibits similarities to RF. Key characteristics of THz communications include (i) the widely available bandwidth to support very high data rates and (ii) the high path loss that occurs at high frequencies (requiring highly directional antennas). The narrow beamwidths generated by highly directional antennas reduce interference. The small wavelength of THz signals allows for a significantly larger number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array technologies to overcome range limitations.

[0082] Advanced Air Mobility (AAM): AAM can be a broad concept encompassing urban air mobility (UAM), regional air mobility (RAM), and uncrewed aerial systems (UAS). For example, AAM can include UAM, RAM, UAS, and uncrewed aerial vehicles (UAVs).

[0083] - Autonomous driving (self-driving): V2X (vehicle to everything), a key element in building autonomous driving infrastructure, can be a technology that allows cars to communicate and share with various elements on the road for autonomous driving, such as vehicle to vehicle (V2V) wireless communication and vehicle to infrastructure (V2I) wireless communication.

[0084] Non-terrestrial network (NTN): NTN can refer to a network or network segment that utilizes radio frequency (RF) resources mounted on satellites (or UAS platforms). NTN services may be considered to secure wider coverage or provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0085] - Integrated sensing and communication (ISAC): Wireless sensing is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the characteristics of the environment and / or objects within the environment.

[0086] - Reconfigurable intelligent surface (RIS): RIS can be used to manipulate and enhance signal propagation in wireless communication environments. For example, a RIS can be composed of many small antennas, or metasurfaces, arranged on a surface, each of which can actively control the phase, amplitude, polarization, etc. of the reflected signal. For example, a RIS can improve signal reception by controlling the path, phase, and / or intensity of the propagating signal. For example, in the case of a RIS, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For example, because a RIS can be reconfigured to suit different environments, it can meet diverse communication requirements and operate effectively in dynamic network environments.

[0087] FIG. 7 illustrates an example of a communication scenario based on a 6G system, according to an embodiment of the present disclosure. The embodiment of FIG. 7 may be combined with various embodiments of the present disclosure, and some descriptions, functions, procedures, proposals, methods, and / or operations of the embodiments may be omitted.

[0088] Referring to FIG. 7, NTN communication can be performed based on satellite networks, high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS), and terminals capable of aerial communication (e.g., AAMs). For example, to improve coverage, etc., devices such as satellite networks, HIBS, and terminals capable of aerial communication (e.g., AAMs) can act as relays. For example, an AAM can communicate with a base station, a satellite network, etc., and / or an AAM can communicate directly with a terminal, another AAM, etc.

[0089] Meanwhile, in the NR system, a terminal can be configured with a measurement gap (MG) for intra-cell or inter-cell measurements from a base station. A terminal that has explicitly been configured with an MG may not expect PUCCH / PUSCH / SRS (sounding reference signal) transmission or PDCCH / PDSCH / CSI-RS reception during the MG period, especially when the measurement is based on SSB (synchronization signal block) reception. For example, the terminal does not expect to transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / CSI-RS. When the base station configures an MG for the terminal based on the timing of SSB reception, the terminal can typically have an MG period every 20 ms, and each MG period can have a length of 1 to 5 ms. If there is an MG period of 5 ms for every 20 ms period, the terminal may not be able to perform PUCCH / PUSCH / SRS transmission or PDCCH / PDSCH / CSI-RS reception for 5 ms every 20 ms, which may affect the availability of the terminal.

[0090] Meanwhile, when using XR (eXtended Reality) services that are sensitive to latency, the unschedulable intervals due to MG can cause greater problems. For example, a terminal that has been configured with semi-persistent scheduling (SPS) / configured grant (CG) radio resources from a base station to receive or transmit periodic sensor information may not be able to perform SPS / CG transmissions if the MG interval and the SPS / CG transmission opportunity overlap. For example, the settings that bring about scheduling restrictions or measurement gap settings can be very diverse, and the operation of skipping / cancelling one of them based on the time when the terminal receives control information from the base station can cause unnecessary complexity.

[0091] Considering these points, we can consider the operation between the terminal and the base station, which allows transmission on the MG according to certain criteria. This control can be achieved through DCI on the PDCCH. Meanwhile, to control the terminal operation on the MG after receiving the DCI, a PDCCH at an appropriate location that takes into account the terminal's processing time may be required. For example, a PDCCH at an appropriate location may be required to control the terminal operation on various MGs established / occurring within the cell.

[0092] For example, the PDCCH can carry DCI. For example, the PCCCH (e.g., DCI) can carry the transmission format and resource allocation of the downlink shared channel (DL-SCH), frequency / time resource allocation information for the uplink shared channel (UL-SCH), paging information for the paging channel (PCH), system information on the DL-SCH, frequency / time resource allocation information for upper layer control messages such as the random access response (RAR) transmitted on the PDSCH, transmission power control commands, information regarding activation / release of configured scheduling (SPS / CS), etc. For example, various DCI formats can be provided depending on the information in the DCI.

[0093] Table 3 illustrates DCI formats transmitted via PDCCH.

[0095] For example, DCI format 0_0 can be used to schedule a TB-based (or TB-level) PUSCH, and DCI format 0_1 ​​can be used to schedule a TB-based (or TB-level) PUSCH or a CBG (code block group)-based (or CBG-level) PUSCH. For example, DCI format 1_0 can be used to schedule a TB-based (or TB-level) PDSCH, and DCI format 1_1 can be used to schedule a TB-based (or TB-level) PDSCH or a CBG-based (or CBG-level) PDSCH. For example, DCI format 0_0 / 0_1 can be referred to as UL grant DCI or UL scheduling information, and DCI format 1_0 / 1_1 can be referred to as DL grant DCI or UL scheduling information. For example, DCI format 2_0 can be used to convey dynamic slot format information (e.g., dynamic SFI) to the terminal, and DCI format 2_1 can be used to convey downlink pre-emption information to the terminal. For example, DCI format 2_0 and / or DCI format 2_1 can be conveyed to the terminals within a group via a group common PDCCH, which is a PDCCH conveyed to the terminals defined as a group.

[0096] For example, the PDCCH / DCI may include a cyclic redundancy check (CRC), and the CRC may be masked / scrambled with various identifiers (e.g., radio network temporary identifier, RNTI) depending on the owner or usage of the PDCCH. For example, if the PDCCH is for a specific terminal, the CRC may be masked with a cell-RNTI (C-RNTI). For example, if the PDCCH is for paging, the CRC may be masked with a paging-RNTI (P-RNTI). For example, if the PDCCH is for system information (e.g., a system information block, SIB), the CRC may be masked with a system information RNTI (SI-RNTI). For example, if the PDCCH is for a random access response, the CRC may be masked with a random access-RNTI (RA-RNTI).

[0097] In this disclosure, for convenience of explanation, examples are provided based on the NR system. However, the proposed methods are not limited to specific NR transmission and reception formats unless otherwise specified. Furthermore, in this disclosure, for convenience of explanation, examples are provided based on the characteristics and structure of XR services. However, the proposed methods are not limited to specific support of XR services unless otherwise specified. Therefore, it is self-evident that the methods proposed in this disclosure can be applied to all wireless communication transmission and reception structures and services, even without a separate description.

[0098] In the present disclosure, MG may refer to not only an MG for inter-cell measurements, but also SMTC (SSB measurement timing) settings for intra-cell / intra-frequency measurements, time window settings that cause scheduling restrictions, etc. For example, MG may include at least one of the following sections:

[0099] - Measurement gaps in NR inter / intra-frequency RRM measurement

[0100] - Measurement gaps in inter RAT RRM measurement

[0101] - Scheduling restriction in NR inter / intra-frequency RRM measurement without measurement gap

[0102] - Scheduling restriction in L1-RSRP measurement for reporting

[0103] - RLM (radio link monitoring) measurement

[0104] - Beam failure detection measurements

[0105] - Network controlled small gap (NCSG) where there are two interruptions in each NCSG occasion and scheduling restrictions apply during measurement length (ML) of the NCSG occasion

[0106] - Multi-universal subscriber identity module (MUSIM) gaps resulting from one or more per-UE MUSIM gap patterns and used for MUSIM purpose

[0107] - UL gaps for Tx power management, applicable only for NR FR2

[0108] In the present disclosure, a terminal can be configured with an intra-cell or inter-cell measurement gap (MG) from a base station, and the terminal can periodically perform measurements on an adjacent cell or a current serving cell on the MG for purposes such as RRM. In this case, when the terminal is instructed or configured by the base station to transmit or receive one or more scheduling for an XR service on the MG, or when transmission or reception on a specific MG is allowed and measurement operation on a specific MG is prevented if necessary, a method for allocating a PDCCH MO (monitoring occasion) that receives a DCI that controls this, a method for receiving the DCI to control transmission / reception and measurement operation on the MG, and a device supporting the same are proposed.

[0109] For example, for this purpose, the proposed method may include a method in which a base station allocates PDSCH / PUSCH radio resources to a terminal, a method in which the terminal performs downlink reception and uplink transmission on the allocated radio resources, a method in which a HARQ-ACK PUCCH response is transmitted in response to a PDSCH reception result, and a method in which a retransmission DCI of the base station is received through a PDCCH after a PUSCH transmission. In addition, for example, the proposed method may include a process in which a terminal transmits a signal and channel to inform its capabilities and / or service requirements, and a process in which the base station receives the signal and channel.

[0110] According to an embodiment of the present disclosure, a PDCCH may be generated in front of each MG, and only a specific DCI format may be received on the PDCCH. For example, when discontinuous reception (DRX) is configured, the PDCCH may be conditionally received outside of the onduration and active time. Furthermore, for example, when an MG is present, the PDCCH may be always received, or only when an MG is present and another scheduling is present on the MG.

[0111] According to an embodiment of the present disclosure, only specific DCI formats can be received using only the MO in front of the MG among the generated PDCCH MOs. For example, when DRX is configured, the PDCCH can be conditionally received outside of the onduration and active time. Furthermore, for example, when the MG is present, the PDCCH can be received always, or only when the MG is present and another scheduling is present on the MG.

[0112] Additionally, for example, in a PDCCH overbooking operation, if there is no MG regardless of the index, it can be unconditionally processed as a lower priority.

[0113] For example, the terminal can receive configuration of MG sections for RRM, etc. from the base station through RRC signaling. For example, information about the configured MG sections can include information about the priority of each MG section, or an index of a PDCCH, CSI-RS, SR (scheduling request), SPS / CG configuration associated therewith, etc. Specifically, for example, a configuration (e.g., search space configuration) that allows reception / transmission on the MG section proposed in the present disclosure can be included.

[0114] For example, the terminal can determine a PDCCH monitoring opportunity in which a DCI allowing reception / transmission on the MG section can be received according to a given setting and a proposed method, and can selectively attempt DCI detection according to the method proposed in the present disclosure at the corresponding PDCCH monitoring opportunity.

[0115] Additionally, for example, the terminal may receive a scheduling message or SPS / CG configuration for PDSCH reception or PUSCH transmission on the MG section from the base station.

[0116] For example, when a terminal receives a DCI allowing reception / transmission on an MG section proposed in the present disclosure, based on the contents contained in the DCI and the proposed method, continuous reception / transmission may be allowed in all or part of a specific MG section, or reception / transmission may be allowed in all or part of a nearby MG section. In addition, for example, measurement operations of the terminal on the corresponding MG section may be prevented.

[0117] The method proposed in this disclosure may be applied by selecting any of the following methods. For example, each method may operate independently without separate combinations, or one or more methods may be combined and operated in a linked manner. Some terms, symbols, and sequences used for explanation may be replaced with other terms, symbols, and sequences, as long as the proposed principles are maintained.

[0118] The method proposed in the present disclosure may be determined to be applied only when the terminal receives related configuration information from the base station (or core network), and at this time, a higher layer signal (e.g., SIB or RRC signaling) may be used for the configuration information, or a method in which activation / deactivation is indicated through separate signaling (e.g., DCI or MAC signaling) for the configured information may be used together. In addition, for example, the terminal may report information (e.g., capability) on whether the proposed method is supportable, and the base station (or core network) may be determined to receive the same.

[0119] Proposal 1: DCI format for measurement gap skipping / canceling

[0120] For example, a separate DCI format for MG cancellation / skip can be defined. This DCI format can be used, for example, to control transmission / reception and measurement operations on the MG.

[0121] For example, the DCI format may include at least one of the following fields:

[0122] (1) MG Cancellation Index (optional): For example, this may be a field indicating the index of the MG to be controlled. For example, the MG Cancellation Index may be configured as a separate RRC parameter in the RRC configuration associated with each measurement gap. For example, the MG Cancellation Index pool may be shared regardless of the measurement gap type. For example, it may be configured to have different values. For example, when the MG Cancellation Index may be configured in measGapConfig and SSB-MTC, each configured MG Cancellation Index may be a unique index in the entire measGapConfig and SSB-MTC. This allows, for example, different types of measurement gaps to be indicated through a single DCI format. For example, if the MG Cancellation Index does not exist, it may operate regardless of the MG type. In this case, for example, the MG targeted by the DCI format may be defined in advance or configured through higher layer signaling. For example, if the MG cancellation index does not exist, the closest MG among the MGs targeted by the corresponding DCI format can be the target.

[0123] (2) Cancel / Skip Indicator: For example, this could be a field indicating whether to cancel / skip MG or turn it on.

[0124] - Cancel / Skip (bit value 1): For example, measurement operations on the MG can be skipped, and uplink transmission / downlink reception can be performed / allowed.

[0125] - On (bit value 0): For example, uplink transmission / downlink reception on the MG can be prevented and measurement operations can be performed.

[0126] For example, conversely, a bit value of 0 may indicate the cancel / skip operation, and a bit value of 1 may indicate the on operation.

[0127] (3) Cancel / Skip Application Point: For example, this could be an (optional) field for detailed settings for transmission / reception on MG.

[0128] - T1 (optional): For example, this could be the symbol length from the PDCCH where the DCI format is transmitted to the first point where a cancel / skip indicator is applied.

[0129] - T2 (optional): For example, this is the length of the time interval to which the cancel / skip indicator applies, which may indicate the number of symbols / slots / subframes or the number of MGs to which the cancel / skip indicator applies.

[0130] For example, instead of a cancel / skip indicator, the following N cancel / skip indicators may be included in the DCI format.

[0131] (4) N cancel / skip indicators: For example, this is a field indicating whether to cancel / skip or turn on the MG, and may have a size of N bits for N cancel / skip indicators. For example, each bit of the bitmap may correspond to a slot in the MG section (e.g., 6 bits if the MG section consists of 6 slots). For example, if the bitmap length is shorter than the MG section, the remaining slots may follow the last cancel / skip indicator value. For example, for the bit value 0, uplink transmission / downlink reception in the corresponding slot may be prevented, and a measurement operation may be performed. For example, for the bit value 1, the measurement operation on the MG may be skipped, and uplink transmission / downlink reception may be performed / allowed. For example, in contrast to the above, a bit value of 1 may indicate an uplink / downlink transmission / reception prevention and measurement operation, and a bit value of 0 may indicate an uplink / downlink transmission / reception performance / allowance operation and an omission of measurement. For example, the N may be a value set via upper layer signaling.

[0132] For example, instead of a cancel / skip indicator, the DCI format could contain fields like:

[0133] (5) N cancel / skip indicators: For example, this is a field indicating whether to cancel / skip or turn on the MG, and may have a size of N bits for N cancel / skip indicators. For example, in case of ON (bit value 0), uplink transmission / downlink reception on the MG may be prevented, and a measurement operation may be performed. For example, in case of cancel / skip (bit value 1), the measurement operation on the MG may be omitted, and uplink transmission / downlink reception may be performed / allowed. For example, conversely, a bit value of 0 may indicate the cancel / skip operation, and a bit value of 1 may indicate the on operation. For example, the N may be a value set through upper layer signaling.

[0134] For example, instead of a cancel / skip indicator, the DCI format could contain fields like:

[0135] (6) N-bit Cancel / Skip Indicator: For example, if 0 is indicated, it can be in the "ON" state for consecutive slots or MG periods, and if a non-zero value is indicated, it can be in the "Cancel / Skip" state for the indicated number of consecutive slots or MG periods. Through this, it may be possible to perform measurement operations or limit transmission / reception for only some consecutive slots within an MG period, for example. For example, the N may be a value set through upper layer signaling.

[0136] For example, when N cancel / skip indicators are used in the above DCI format field configuration, each indicator can be utilized to indicate each slot within the corresponding section rather than the entire MG section. For example, when the MG section is composed of multiple slots, each of the N cancel / skip indicators can indicate whether to cancel / skip an individual slot within the MG section. In this case, for example, N can be set to be equal to or greater than the number of slots constituting the MG section. Through this, for example, the base station can more precisely control measurement operations and transmission / reception operations on a slot-by-slot basis even within the MG section. Similarly, for example, even when a single cancel / skip indicator is used in the above DCI format field configuration, slot-by-slot control within the MG section can be supported by replacing it with N cancel / skip indicators. For example, even when a DCI format that previously included only a single cancel / skip indicator was used, control for individual slots within the MG section can be enabled by changing it to a form that includes N cancel / skip indicators.

[0137] For example, when the above DCI format field configuration is used, if ON or CANCEL / SKIP is indicated for a certain MG, the once indicated content can be continuously applied until CANCEL / SKIP or CANCEL / SKIP or CANCEL is indicated again.

[0138] For example, when the above DCI format field configuration is used, if on or cancel / skip is indicated for a certain MG, the cancel / skip indication may be applied to the first MG after a certain time T1 from the last symbol of the PDCCH in which the DCI format indicating this is received.

[0139] For example, when the above DCI format field configuration is used, if on or cancel / skip is indicated for a certain MG, the cancel / skip indication may be applied to the MG during a certain time period T2 after a certain time period T1 from the last symbol of the PDCCH in which the DCI format indicating this is received.

[0140] For example, when the above DCI format field configuration is used, if N cancel / skip indicators are indicated, the cancel / skip indicators can be applied to N MG sections after a certain time T1 from the last symbol of the PDCCH in which the DCI format indicating the same is received.

[0141] For example, when the above DCI format field configuration is used, if N cancel / skip indicators are indicated, the cancel / skip indicators can be applied to N slots after a certain time T1 from the last symbol of the PDCCH in which the DCI format indicating the same is received.

[0142] For example, when the above DCI format field configuration is used, if N cancel / skip indicators are indicated, the cancel / skip indicators can be applied to N MG sections during a certain time T2 after a certain time T1 from the last symbol of the PDCCH in which the DCI format indicating the same is received.

[0143] For example, in each example, T1 and / or T2 may be indicated via the DCI format as described above, may be set via higher layer signaling, may be a predefined value, or may be a value reported via the capability report of the terminal. For example, T1 and T2 may be jointly coded and transmitted via a single field.

[0144] For example, if the terminal detects the DCI format in the PDCCH received before the MG, the terminal can interpret the fields and control the transmission / reception and measurement operations for the indicated MG. For example, if the on indicator is set, the terminal may not perform uplink transmission and downlink reception in the corresponding MG section, and the terminal may only perform measurement operations. For example, if the cancel / skip indicator is set, the terminal may skip the measurement operation in the MG section, and uplink transmission and downlink reception may be performed or allowed.

[0145] For example, when N cancel / skip indicators are used in the above DCI format field configuration, each indicator can be utilized to indicate each slot within the corresponding section rather than the entire MG section. For example, when the MG section is composed of multiple slots, each of the N cancel / skip indicators can indicate whether to cancel / skip an individual slot within the MG section. In this case, for example, N can be set to be equal to or greater than the number of slots constituting the MG section. Through this, for example, the base station can more precisely control measurement operations and transmission / reception operations on a slot-by-slot basis even within the MG section. Similarly, for example, even when a single cancel / skip indicator is used in the above DCI format field configuration, slot-by-slot control within the MG section can be supported by replacing it with N cancel / skip indicators. For example, even when a DCI format that previously included only a single cancel / skip indicator was used, control for individual slots within the MG section can be enabled by changing it to a form that includes N cancel / skip indicators.

[0146] For example, by defining these separate DCI formats, base stations can more flexibly and dynamically control terminal operations on MGs. This can help ensure the quality of critical services, such as XR services, while minimizing measurement overhead. Furthermore, terminals can clearly recognize MG-related control information and optimize their operations accordingly.

[0147] Proposal 1-1: Measurement gap skipping / canceling with repetition

[0148] For example, we can consider scheduling repetitive transmissions using the DCI format described in Proposal 1. For example, the same DCI format defined in Proposal 1 can be used to handle measurement gaps (MGs) when scheduling repetitive transmissions. For example, the DCI format can be used to control collisions between repetitive transmissions and MGs, and MG handling for repetitive transmissions can be performed by extending the interpretation of existing fields.

[0149] For example, the DCI format field of Proposal 1 can be interpreted and utilized as follows for repeat transmission situations:

[0150] (1) MG Cancelling Index: For example, this field may indicate the index of the MG associated with the repeated transmission. For example, the MG Cancelling Index may be set as a separate RRC parameter in the RRC configuration associated with each repeated transmission.

[0151] (2) Cancel / Skip Indicator: For example, this field can indicate whether MG is to be canceled / skipped or turned on during a repeat transmission. For example, the cancel / skip indicator can be applied only to the first repeat transmission. This can ensure compatibility with existing implementations by reducing the implementation complexity of the MG handling mechanism in both the terminal and the base station, and making it operate in a manner similar to the MG handling mechanism for a single transmission. For example, the cancel / skip indicator can be applied to all repeat transmissions.

[0152] (3) N-bit Cancel / Skip Indicator: For example, this field can indicate whether MG cancels consecutive instances in a repeat transmission. For example, if 0 is indicated, it can be in the "On" state in that repeat transmission instance, and if a non-zero value is indicated, it can be in the "Cancel / Skip" state in the indicated number of consecutive repeat transmission instances.

[0153] For example, if the terminal detects the DCI format in the PDCCH received prior to the repeated transmission, the terminal can interpret the fields and perform MG handling for the indicated repeated transmission. For example, if the cancel / skip indicator is set to 1, the terminal can cancel the MG in the corresponding repeated transmission sequence, and the terminal can perform uplink transmission and downlink reception.

[0154] For example, when the above DCI format field configuration is used, if MG cancellation / skip is indicated for a certain repetitive transmission, the MG cancellation / skip indication may be applied from the first repetitive transmission instance after a certain time T1 from the last symbol of the PDCCH in which the DCI format indicating this is received.

[0155] For example, when the above DCI format field configuration is used, if MG cancellation / skip is indicated for a certain repetitive transmission, the MG cancellation / skip indication may be applied to repetitive transmission instances during a certain time period T2 after a certain time T1 from the last symbol of the PDCCH in which the DCI format indicating this is received.

[0156] For example, in each example, T1 and / or T2 may be indicated via the DCI format as described above, may be set via higher layer signaling, may be a predefined value, or may be a value reported via the capability report of the terminal. For example, T1 and T2 may be jointly coded and transmitted via a single field.

[0157] For example, by applying the DCI format of Proposal 1 to repetitive transmissions in this manner, the base station can more flexibly and dynamically control collisions between repetitive transmissions and MGs. This can help ensure the quality of delay-sensitive services, such as XR services, while maintaining necessary measurement opportunities. Furthermore, for example, the terminal can clearly recognize repetitive transmissions and MG-related control information and optimize its operations accordingly.

[0158] For example, when repeat transmission is used, consideration may be given to ways to prevent MG skipping from being available or expected by the terminal. For example, this could be implemented for the following reasons and in the following manner:

[0159] For example, the MG skip feature can be disabled for a given transmission via signaling. For this purpose, the following RRC parameter can be introduced, for example:

[0160] - mgSkipDisabledForRepetition: For example, when set to BOOLEAN TRUE, it can indicate that the MG skip function is disabled for repetitive transmissions. In this case, for example, if a repetitive transmission is indicated, the MG skip function can be applied only to the first repetitive transmission. For example, if this parameter is FALSE, the MG skip function can be applied to all scheduled repetitive transmissions.

[0161] - mgSkipEnabledForRepetition: For example, when set to BOOLEAN FALSE, it can indicate that the MG skip function is disabled for repetitive transmissions. In this case, for example, if a repetitive transmission is indicated, the MG skip function can be applied only to the first repetitive transmission. For example, if this parameter is TRUE, the MG skip function can be applied to all scheduled repetitive transmissions.

[0162] For example, if a scheduling DCI for repetitive transmission (scheduling with a repeat transmission count of two or more) is detected, a rule can be defined so that the terminal ignores the MG cancellation index or cancellation / skip indicator included in the DCI. For example, the terminal may not expect both repetitive transmission and MG skip indications to be indicated at the same time.

[0163] For example, if repetitive transmission is enabled, a rule can be defined to automatically disable the MG skip function via DCI scheduling. In this case, for example, the terminal may not attempt MG skip without separate signaling.

[0164] Proposal 2: On-demand PDCCH MO before measurement gap

[0165] For example, in order to receive DCI for controlling terminal operations on an MG, a PDCCH capable of receiving such DCI may be generated in front of each MG, and an MG control DCI format may be received on the PDCCH. At this time, for example, the DCI format described in Proposal 1 may be used. Through this, for example, the terminal can efficiently control transmission / reception and measurement operations on the MG.

[0166] For example, to generate PDCCH in front of each MG, the following methods may be considered.

[0167] For example, a base station may share MG configuration information that generates a PDCCH with a terminal. For example, this may include an MG configuration index, the type of MG configuration, and / or the MG period, length, offset, etc. For example, some of the information may be predefined.

[0168] For example, the base station can set a monitoring occasion for PDCCH transmission by designating a specific time point or interval before each MG. For example, this interval can indicate a time point at which the UE should monitor the PDCCH to receive MG-related control information. For example, this can be a certain time T before the start of each MG. For example, the certain time T is the time it takes for the UE to receive and process the MG control message, which can be indicated through the DCI format, can be set through higher layer signaling, can be a predefined value, or can be a value reported through the capability report of the UE. For example, the base station can set a (CORESET and) search space set configuration for the UE. For example, the period and offset parameters configured in the corresponding search space can be ignored or excluded, and the corresponding search space, e.g., the PDCCH monitoring interval, can be configured at a time point / slot before T (or a specific time interval with this as the last time point / slot) from the start of the MG according to the above.

[0169] For example, a terminal can perform PDCCH monitoring at a designated time point prior to each MG based on configured MG configuration information and PDCCH monitoring interval information. To achieve this, for example, the terminal can blindly decode the PDCCH at that time point to determine whether DCI for itself exists.

[0170] For example, the base station can transmit MG control DCI for the terminal via the PDCCH, if necessary. For example, this DCI can use a separate DCI format for the MG control DCI format described above.

[0171] For example, if a UE detects an MG-related DCI from a PDCCH received, the UE can control operations in one or more upcoming MG sections according to the instructions of the DCI. For example, according to the instructions of the DCI, the MG can be kept on and measurements can be performed, or the MG can be canceled / omitted and data transmission / reception can be performed. Meanwhile, for example, if no MG-related DCI is detected as a result of monitoring the PDCCH prior to a specific MG, the UE can regard / assume the MG as on, or the base station can configure which operation the UE will perform between the on state and cancellation / omission when no MG-related DCI is detected.

[0172] For example, after the MG period ends, the terminal can perform normal operations until the next MG. Furthermore, for example, the terminal can repeat the process of receiving control information by monitoring the PDCCH again before the next MG.

[0173] Additionally, when DRX (discontinuous reception) is configured, the terminal can conditionally receive PDCCH outside of the on-duration and active time. For example, at least one of the following two conditions may be considered:

[0174] - If the above PDCCH is always received regardless of DRX

[0175] - When receiving PDCCH only when other uplink transmission and downlink reception scheduling exists in the MG section.

[0176] Through this, for example, the terminal can appropriately control transmission / reception and measurement operations on the MG even under DRX settings.

[0177] The method according to the embodiment of the present disclosure reduces terminal power consumption and efficiently performs measurement operations while ensuring the quality of important services, such as XR services. This is expected to contribute to improved terminal performance and enhanced user experience in 5G mobile communication systems.

[0178] Proposal 3: MO masking based on measurement gap configuration

[0179] For example, in order to receive DCI for controlling terminal operation on an MG, a PDCCH capable of receiving such DCI can be configured, and the terminal can detect the DCI on the PDCCH only when the PDCCH occurred for a certain period of time before the MG. For example, an MG control DCI format can be received on the PDCCH. In this case, for example, the DCI format described in Proposal 1 can be used. Through this, for example, the terminal can efficiently control transmission / reception and measurement operations on the MG.

[0180] For example, to selectively receive PDCCH only in front of each MG, the following method may be considered.

[0181] For example, a base station may share MG configuration information with a terminal. This may include, for example, an MG configuration index, an MG configuration type, and / or an MG period, length, offset, etc. For example, some of the information may be predefined.

[0182] For example, a base station can configure a search space for PDCCH monitoring for MG control to a terminal. For example, this search space can be used for MG-related control information.

[0183] For example, a base station can set two offsets to a terminal via RRC signaling, etc.:

[0184] - First Offset: For example, this can be the time offset from the MG to the point in time at which PDCCH monitoring should start before the MG starts. For example, this value can be set in units of ms, symbols, slots, subframes, etc.

[0185] - Second offset: For example, this may be the minimum time gap from the PDCCH monitoring time to the MG start time. For example, this may be to ensure sufficient time for the UE to receive and process the PDCCH. For example, this value may be set in units of ms, symbols, slots, subframes, etc. For example, the UE may perform PDCCH monitoring for MG control during the period from the time prior to the first offset (from the MG start) to the time prior to the second offset (from the MG start).

[0186] For example, instead of the second offset, a specific time interval can be set, and the terminal can perform PDCCH monitoring for MG control during the specific time interval starting from a time prior to the first offset (from the start of the MG). In this case, for example, the time from the end of the time interval to the start of the MG can be restricted / regulated to be greater than or equal to the minimum time interval required for the terminal to process the received signal.

[0187] Alternatively, for example, these offset values ​​may be calculated based on MG configuration information, may be set considering terminal capability information, or may be predefined values.

[0188] For example, the terminal can perform PDCCH monitoring based on the configured MG configuration information, search space configuration information, and two offset information. For example, the terminal can start PDCCH monitoring from a point in time prior to the first offset from the start time of each MG, and the terminal can stop PDCCH monitoring after a minimum time gap defined by the second offset.

[0189] For example, the base station can transmit MG control DCI for the terminal via the PDCCH, if necessary. For example, this DCI can use the MG control DCI format described above.

[0190] For example, if the terminal detects an MG-related DCI from a PDCCH received during the time defined by the first offset, the operation in one or more upcoming MG segments may be controlled according to the instructions of the DCI.

[0191] For example, after the MG period ends, the terminal may skip monitoring PDCCHs in the corresponding search space until the time defined by the first offset before the next MG. Then, for example, when the time defined by the first offset before the next MG arrives, the terminal may start monitoring PDCCHs again and repeat the process of receiving control information. For example, if the terminal detects MG-related DCIs from PDCCHs received during a certain time before the MG, operations in one or more upcoming MG periods may be controlled according to the instructions of the DCI.

[0192] For example, in this manner, the terminal can selectively perform PDCCH monitoring for MG control based on the MG configuration and two explicitly configured offset information, thereby reducing power consumption due to unnecessary PDCCH monitoring. Furthermore, for example, the base station can more flexibly manage PDCCH resources for MG control DCI transmission.

[0193] Additionally, when DRX (discontinuous reception) is configured, the terminal can conditionally receive PDCCH outside of the on-duration and active time. For example, at least one of the following two conditions may be considered:

[0194] - When the PDCCH is always received based on the MG setting and the two set offset information regardless of DRX.

[0195] - When receiving PDCCH based on MG configuration and two set offset information when other uplink transmission and downlink reception scheduling exist on the MG section.

[0196] Through this, for example, the terminal can appropriately control transmission / reception and measurement operations on the MG even under DRX settings.

[0197] The method according to the embodiment of the present disclosure reduces terminal power consumption and efficiently performs measurement operations while ensuring the quality of important services, such as XR services. This is expected to contribute to improved terminal performance and enhanced user experience in 5G mobile communication systems.

[0198] Proposal 4: PDCCH overbooking handling based on measurement gap configuration

[0199] For example, a search space set for PDCCH monitoring for MG control may overlap with another search space, and some search space settings may not be received due to limitations on the number of blind detections (BDs) and the number of non-overlapping control channel elements (CCEs) in the slot. This situation is a problem that may also occur in the conventional PDCCH overbooking processing operation, and considering the importance of MG control, the following priority rules may be applied. For example, a search space set for PDCCH monitoring for MG control may be a search space set to monitor an MG control DCI format, and may be a search space to monitor a DCI format described in Proposal 1.

[0200] For example, if an MG is established within a certain time from the search space for MG control, and the search space for MG control overlaps with another search space, the search space for MG control may be monitored preferentially, and / or the other search space may be dropped due to BD / CCE limitations.

[0201] For example, if an MG is not established within a certain time from the search space for MG control, and the search space for MG control overlaps with another search space, the other search space may be monitored preferentially, and / or the search space for MG control may be dropped due to BD / CCE limitations.

[0202] For example, to apply these priority rules, the following procedures may be considered:

[0203] For example, a base station can set the priority of a search space for MG control via RRC signaling, etc. This can be, for example, a single search space index, and can be set as "priority based on MG involvement," etc.

[0204] For example, the base station can set two offsets for MG control via RRC signaling, etc. For example, a separate offset can be set for each search space configuration configured to monitor MG control DCI. For example, the first offset T1 can indicate the time point at which corresponding PDCCH monitoring can start from a certain MG. For example, the second offset T2 can indicate the minimum time interval from the end of PDCCH monitoring to the start of the MG. For example, this can be to ensure a minimum processing time for the UE to prepare for the MG.

[0205] For example, the terminal can determine the PDCCH monitoring operation in each slot based on the configured MG configuration information, search space configuration information, and search space priority information for MG control. Specifically, for example, the terminal can check whether there is MG involvement during the PDCCH monitoring period, and if there is an overlapping search space, it can exclude a specific search space as follows.

[0206] For example, if there is an instruction or set MG section that can be the target of an MG control DCI between time X that is T2 away from the search space for MG control and time Y that is T1 away from the search space for MG control, the search space for MG control can be monitored preferentially, and other search spaces can be dropped as needed.

[0207] For example, if there is an instructed or set MG interval that can be the target of an MG control DCI between time X that is T2 away from the search space for MG control and time Y that is T1 away from the search space for MG control, another search space can be monitored preferentially, and the search space for MG control can be dropped as needed.

[0208] For example, a terminal may perform PDCCH monitoring considering BD / CCE limitations within a search space selected according to priority.

[0209] For example, in this manner, the search space for MG control can be prioritized considering the importance of MG control, and PDCCH monitoring operations can be performed accordingly. This can improve the reception performance of MG-related control information. Furthermore, for example, by preferentially monitoring other search spaces in non-MG sections, the reception performance of general control information can also be guaranteed. Furthermore, for example, the proposed technique can be applied in conjunction with conventional PDCCH over-reservation processing operations to comprehensively improve detection performance in situations where PDCCH monitoring resources are limited.

[0210] For example, through the proposed method, efficient PDCCH monitoring can be performed within limited resources by considering the balance between MG control DCI and general DCI.

[0255] FIG. 12 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.

[0256] Referring to FIG. 12, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operations / functions of FIG. 12 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 11. The hardware elements of FIG. 12 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 11. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 11. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 11, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 11.

[0257] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 12. Here, the codeword is an encoded bit sequence of an information block. The information block can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).

[0258] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010). The scramble sequence used for scrambling is generated based on an initialization value, and the initialization value may include ID information of the wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by a precoding matrix W of N*M. Here, N is the number of antenna ports, and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on complex modulation symbols. In addition, the precoder (1040) can perform precoding without performing transform precoding.

[0259] The resource mapper (1050) can map modulation symbols of each antenna port to time-frequency resources. The time-frequency resources can include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. The signal generator (1060) generates a wireless signal from the mapped modulation symbols, and the generated wireless signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) can include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0260] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 12. For example, a wireless device (e.g., 100, 200 of FIG. 11) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
