[0045] FIG. 1 illustrates a communication procedure between devices according to one embodiment of the present disclosure. The embodiment of FIG. 1 may be combined with various embodiments of the present disclosure.

[0046] Referring to FIG. 1, in step S101, the first device and the second device can perform synchronization. For example, the first device may be a terminal and / or at least one of the devices proposed in the present disclosure. For example, the second device may be a base station, a network, a RAN node, an NTN node / cell, a TRP, a terminal and / or at least one of the devices proposed in the present disclosure. For example, the first device may perform an initial cell search operation. For example, the first device may detect at least one synchronization signal transmitted according to a rule predefined by the second device. Here, for example, the synchronization signal may include a plurality of synchronization signals (e.g., primary synchronization signal, secondary synchronization signal, etc.) classified according to structure or use. Through this, the first device can identify the boundaries of the frame, subframe, time unit, slot, and / or symbol of the second device, and the first device can obtain information about the second device (e.g., cell identifier).

[0047] In step S103, the first device may obtain system information transmitted by the second device. For example, the system information may include information related to the attributes, characteristics, and / or capabilities of the second device that are necessary to connect to the second device and use the service. For example, the system information may be classified according to content (e.g., whether it is essential for connection), transmission structure (e.g., the channel used, whether it is provided on-demand), etc. For example, the system information may be classified into a master information block (MIB) and a system information block (SIB). For example, if necessary, the first device may transmit a signal requesting the system information prior to receiving the system information. For example, the request and provision of the system information may be performed after a random access procedure described later.

[0048] In step S105, the first device and the second device may perform a random access procedure. For example, the first device may transmit and / or receive at least one message for the random access procedure (e.g., random access preamble, random access response message, etc.) based on information related to the random access channel of the second device obtained through system information (e.g., channel location, channel structure, structure of supported preamble, etc.). For example, the first device may transmit a preamble (e.g., Msg1) through the random access channel, and the first device may receive a random access response message (e.g., Msg2). The first device may transmit a message (e.g., Msg3) containing information related to the first device (e.g., identification information) to the second device using scheduling information included in the random access response message, and the first device may receive a message (e.g., Msg4) for contention resolution and / or connection establishment. For example, Msg1 and Msg3 can be transmitted and received as a single message (e.g., MsgA), and / or Msg2 and Msg4 can be transmitted and received as a single message (e.g., MsgB).

[0049] In step S107, the first device and the second device may perform signaling of control information. Here, for example, the control information may be defined in various layers, such as a layer controlling the connection (e.g., a radio resource control (RRC) layer), a layer handling mapping between a logical channel and a transmission channel (e.g., a media access control (MAC) layer), and a layer handling a physical channel (e.g., a physical (PHY) layer). For example, the first device and the second device may perform at least one of signaling to establish a connection, signaling to determine settings related to communication, and / or signaling to indicate allocated resources. For example, the control information may be signaled / transmitted through a control channel. For example, the control information and / or the control channel may be used to schedule at least one of data, a data channel (e.g., a shared channel), and / or control information on the data channel.

[0050] In step S109, the first device and the second device may transmit and / or receive data. For example, the first device and the second device may process data based on signaling of control information and transmit and / or receive it. For example, when transmitting data, the first device or the second device may perform at least one of channel encoding, rate matching, scrambling, constellation mapping, layer mapping, waveform modulation, antenna mapping, and / or resource mapping on the information bits. For example, when receiving data, the first device or the second device may perform at least one of signal extraction from resources, antenna-specific waveform demodulation, signal placement considering layer mapping, constellation demapping, descrambling, and / or channel decoding.

[0051] For example, the layers of the radio interface protocol between the first device and the second device can be classified into L1 (layer 1), L2 (layer 2), L3 (layer 3), etc. For example, the physical layer belonging to layer 1 can provide an information transfer service using a physical channel, and the radio resource control (RRC) layer located at layer 3 can perform the role of controlling radio resources between the first device and the second device. To this end, for example, the RRC layer can exchange RRC messages between the first device and the second device.

[0052] FIG. 2 illustrates a radio protocol architecture according to one embodiment of the present disclosure. The embodiment of FIG. 2 may be combined with various embodiments of the present disclosure. For example, FIG. 2(a) may represent a radio protocol stack in the user plane for uplink communication or downlink communication, and FIG. 2(b) may represent a radio protocol stack in the control plane for uplink communication or downlink communication. For example, FIG. 2(c) may represent a radio protocol stack in the user plane for device-to-device communication, and FIG. 2(d) may represent a radio protocol stack in the control plane for device-to-device communication.

[0053] For example, the physical layer can provide information transmission services to upper layers using a physical channel. For example, the physical layer can be connected to the upper layer, the MAC (medium access control) layer, through a transport channel. For example, data can be transmitted between the MAC layer and the physical layer through a transport channel. For example, transport channels can be classified according to how and with what characteristics data is transmitted through a wireless interface. For example, data can be transmitted through a physical channel between different physical layers, for example, between the physical layers of a first device and a second device. For example, the physical channel can be modulated using the OFDM (orthogonal frequency division multiplexing) method, and time and frequency can be utilized as wireless resources.

[0054] For example, the MAC layer can provide services to the upper layer, the RLC (radio link control) layer, through logical channels. For example, the MAC layer can provide mapping functions from multiple logical channels to multiple transmission channels. For example, the MAC layer can provide logical channel multiplexing functions through mapping from multiple logical channels to a single transmission channel. For example, the MAC sublayer can provide data transmission services over logical channels.

[0055] For example, the RLC layer can perform concatenation, segmentation, and reassembly of RLC service data units (SDUs). For example, to guarantee various quality of service (QoS) required by a radio bearer (RB), the RLC layer can provide three modes of operation: transparent mode (TM), unacknowledged mode (UM), and acknowledged mode (AM). For example, AM RLC can provide error correction through automatic repeat requests (ARQ).

[0056] For example, the RRC (radio resource control) layer may be defined only in the control plane. For example, the RRC layer may be responsible for controlling logical channels, transmission channels, and physical channels in relation to the configuration, reconfiguration, and release of radio bearers. For example, RB may refer to a logical path provided by the first layer (e.g., physical layer) and the second layer (e.g., MAC layer, RLC layer, PDCP (packet data convergence protocol) layer, SDAP (service data adaptation protocol) layer, etc.) for data transfer between a first device and a second device.

[0057] For example, the functions of the PDCP layer in the user plane may include the delivery of user data, header compression, and ciphering. For example, the functions of the PDCP layer in the control plane may include the delivery of control plane data and encryption / integrity protection.

[0058] For example, the establishment of an RB can mean the process of defining the characteristics of the wireless protocol layer and channel to provide specific services, and setting each specific parameter and method of operation. For example, an RB can be divided into two types: an SRB (signaling radio bearer) and a DRB (data radio bearer). For example, an SRB can be used as a channel to transmit RRC messages in the control plane, and a DRB can be used as a channel to transmit user data in the user plane.

[0059] For example, a base station-to-terminal transmission (e.g., DL transmission) channel may include at least one of a broadcast channel (BCH) that transmits system information and / or a downlink shared channel (SCH) that transmits user traffic or control messages. For example, traffic or control messages for a downlink multicast or broadcast service may be transmitted via a downlink SCH or via a separate downlink multicast channel (MCH). Meanwhile, an uplink transmission channel may include at least one of a random access channel (RACH) that transmits initial control messages and / or a shared channel (SCH) that transmits user traffic or control messages. For example, a logical channel located above the transmission channel and mapped to the transmission channel may include at least one of a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and / or a multicast traffic channel (MTCH).

[0060] FIG. 3 shows the structure of a wireless frame according to one embodiment of the present disclosure. The embodiment of FIG. 3 can be combined with various embodiments of the present disclosure.

[0061] Referring to FIG. 3, radio frames may be used, for example, in uplink transmission, base station-to-terminal transmission (e.g., DL transmission), and / or device-to-device transmission. For example, a radio frame may have a length of 10 ms and may be defined as two 5 ms half-frames (HF). For example, a half-frame may contain five 1 ms subframes (SF). For example, a subframe may be divided into one or more slots, and the number of slots within a subframe may be determined by subcarrier spacing (SCS). For example, each slot may contain 12 or 14 OFDM(A) symbols according to a cyclic prefix (CP).

[0062] For example, when normal CP is used, each slot may contain 14 symbols. For example, when extended CP is used, each slot may contain 12 symbols. Here, for example, the symbols may include OFDM symbols (or CP-OFDM symbols) and SC-FDMA (single carrier-FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0063] Table 2 below shows the number of symbols per slot (N) according to the SCS setting (u) when Normal CP or Extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot ) exemplifies.

[0064] CP Type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slot Normal CP 15kHz (u=0) 1410 130kHz (u=1) 1420 260kHz (u=2) 1440 4120kHz (u=3) 1480 8240kHz (u=4) 14160 16 Extended CP 60kHz (u=2) 1240 4

[0065] For example, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be configured differently among multiple cells merged into a single terminal. Accordingly, the (absolute time) interval of a time resource (e.g., subframe, slot, or TTI (transmit time interval)) composed of the same number of symbols may be configured differently among the merged cells. For example, in the present disclosure, time resources such as subframes, slots, TTI, etc. may be referred to as time units.

[0066] For example, multiple numerologies or SCSs may be supported to support various services. For example, if the SCS is 15 kHz, a wide area in traditional cellular bands may be supported, and if the SCS is 30 kHz / 60 kHz, dense-urban, lower latency, and wider carrier bandwidth may be supported. For example, if the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz may be supported to overcome phase noise.

[0067] FIG. 4 shows a slot structure of a frame according to one embodiment of the present disclosure. The embodiment of FIG. 4 can be combined with various embodiments of the present disclosure.

[0068] Referring to FIG. 4, for example, a slot may include multiple symbols in the time domain. For example, a carrier may include multiple subcarriers in the frequency domain. For example, a resource block (RB) may be defined as multiple consecutive subcarriers in the frequency domain. For example, a bandwidth part (BWP) may be defined as multiple consecutive (P)RBs ((physical) resource blocks) in the frequency domain and may correspond to a single numerology (e.g., SCS, CP length, etc.). For example, a carrier may include up to N BWPs (where N is a positive integer). For example, data communication may be performed through an active BWP. For example, each element may be referred to as a resource element (RE) in a resource grid and may be mapped to a single complex symbol.

[0069] For example, a BWP can be a continuous set of PRBs in a given numerology. For example, a PRB can be selected from a continuous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0070] For example, the BWP may be at least one of an active BWP, an initial BWP, and / or a default BWP. For example, the terminal may not monitor downlink radio link quality on DL BWPs other than the active DL BWP on the PCell (primary cell). For example, the terminal may not receive PDCCH (physical downlink control channel), PDSCH (physical downlink shared channel), or CSI-RS (channel state information-reference signal) (except for RRM (radio resource management)) outside of the active DL BWP. For example, the terminal may not trigger CSI (channel state information) reporting for an inactive DL BWP. For example, the terminal may not transmit PUCCH (physical uplink control channel) or PUSCH (physical uplink shared channel) outside of the active UL (uplink) BWP. For example, for the downlink, the initial BWP can be given as a consecutive set of resource blocks (RBs) for the remaining minimum system information (RMSI) CORESET (control resource set) (set by the physical broadcast channel (PBCH)). For example, for the uplink, the initial BWP can be given by the system information block (SIB) for the random access procedure. For example, the default BWP can be set by the upper layer. For example, the initial value of the default BWP can be the initial DL BWP.For energy saving, if the terminal fails to detect DCI (downlink control information) for a certain period, the terminal can switch the active BWP of the terminal to the default BWP.

[0071] In the present disclosure, PSCCH may be replaced with a control channel, a physical control channel, a control channel associated with a sidelink, a physical control channel associated with a sidelink, a physical control channel between devices, etc. In the present disclosure, PSSCH may be replaced with a shared channel, a physical shared channel, a shared channel associated with a sidelink, a physical shared channel associated with a sidelink, a physical shared channel between devices, etc. For example, SL communication may be replaced with device-to-device communication. For example, in terms referring to various channels and / or signals associated with SL communication, the SL portion may be replaced with "between devices".

For example, in terms referring to various channels and / or signals associated with UL communication, the UL portion may be replaced with "device-to-base station" or "terminal-to-base station".

[0073] In the present disclosure, a base station-to-terminal physical control channel (e.g., PDCCH) may be replaced with a control channel, a physical control channel, a control channel associated with a downlink, a physical control channel associated with a downlink, a base station-to-device physical control channel, a base station-to-terminal physical control channel, etc. In the present disclosure, a base station-to-terminal physical sharing channel (e.g., PDSCH) may be replaced with a sharing channel, a physical sharing channel, a sharing channel associated with a downlink, a physical sharing channel associated with a downlink, a base station-to-device physical sharing channel, a base station-to-terminal physical sharing channel, etc. For example, DL communication may be replaced with base station-to-device communication or base station-to-terminal communication. For example, in terms referring to various channels and / or signals associated with DL communication, the DL portion may be replaced with "base station-to-device" or "base station-to-terminal".

[0074] 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. In the embodiment of FIG. 5, it is assumed that there are three BWPs.

[0075] Referring to FIG. 5, for example, a common resource block (CRB) may be a numbered carrier resource block from one end of the carrier band to the other, and a PRB may be a numbered resource block within each BWP. For example, point A may indicate a common reference point for the resource block grid.

[0076] For example, BWP is point A, offset from point A (N start BWP ) and bandwidth (N size BWPIt can be set by ). For example, point A may be an external reference point of the PRB of a carrier where the subcarrier 0 of all numerologies (e.g., all numerologies supported by the network in that carrier) are aligned. For example, offset may be the PRB interval between the lowest subcarrier in a given numerology and point A. For example, bandwidth may be the number of PRBs in a given numerology.

[0077] FIG. 6 illustrates a communication structure that can be provided in a 6G system according to one embodiment of the present disclosure. The embodiment of FIG. 6 can be combined with various embodiments of the present disclosure.

[0078] As core implementation technologies for 6G systems, technologies such as artificial intelligence (AI), THz (Terahertz) communication, optical wireless technology, free space optical transmission (FSO) backhaul networks, large-scale MIMO (multiple input multiple output) technology, blockchain, 3D networking, quantum communication, unmanned aerial vehicles, cell-free communication, wireless information and energy transfer (WIET), integration of sensing and communication, integration of access backhaul networks, holographic beamforming, big data analysis, and large intelligent surface (LIS) can be adopted.

[0079] - Artificial Intelligence: Introducing AI into communications can streamline and enhance real-time data transmission. AI can determine how complex target tasks are performed using numerous analyses. For example, AI can increase efficiency and reduce processing latency. Time-consuming tasks such as handover, network selection, and resource scheduling can be performed instantly using AI. AI can also play a significant role in M2M, machine-to-human, and human-to-machine communication. Furthermore, AI can enable rapid communication in Brain-Computer Interfaces (BCI). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0080] - THz Communication: Data transmission rates can be increased by expanding bandwidth. This can be achieved by using sub-THz communication with wide bandwidth and applying advanced large-scale MIMO technology. THz waves, also known as sub-millimeter radiation, generally refer to a frequency band between 0.1 THz and 10 THz with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz-300 GHz band range (Sub-THz band) is considered the primary portion of the THz band for cellular communication. Adding the Sub-THz band to the mmWave band increases 6G cellular communication capacity. Among the defined THz bands, the 300 GHz-3 THz band is located in the far-infrared (IR) frequency band. Although the 300 GHz-3 THz band is part of the optical band, it lies at the boundary of the optical band and immediately following the RF band. Therefore, this 300 GHz-3 THz band exhibits similarities to RF. Key characteristics of THz communication include (i) widely available bandwidth to support very high data transmission rates, and (ii) high path loss occurring at high frequencies (highly directional antennas are indispensable). The narrow beam width generated by highly directional antennas reduces interference. The small wavelength of THz signals allows a much larger number of antenna elements to be integrated into devices and BSs operating in this band. This enables the use of advanced adaptive array technologies that can overcome range limitations.

[0094] - 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 may include UAM, RAM, UAS, and UAVs (uncrewed aerial vehicles).

[0095] - Autonomous driving (self-driving): V2X (vehicle to everything), a core element of building autonomous driving infrastructure, refers to technologies that enable vehicles to communicate and share with various elements on the road to perform autonomous driving, such as wireless communication between vehicles (vehicle to vehicle, V2V) and between vehicles and infrastructure (vehicle to infrastructure, V2I).

[0096] - Non-terrestrial Network (NTN): An NTN may refer to a network or network segment that utilizes RF (radio frequency) resources mounted on a satellite (or UAS platform). The use of NTN services may be considered to secure wider coverage or to provide wireless communication services in locations where the installation of wireless communication base stations is difficult.

[0097] - 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.

[0098] - Reconfigurable Intelligent Surface (RIS): An RIS can be used to manipulate and enhance signal propagation in a wireless communication environment. For example, an 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 instance, an RIS can improve signal reception by controlling the path, phase, and / or strength of the propagating signal. For instance, power consumption can be very low because power is consumed only for controlling the phase and amplitude of the small antennas. For instance, since an RIS can be reconfigured to suit various environments, it can meet diverse communication requirements and operate effectively in dynamic network environments.

[0099] 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 can be combined with various embodiments of the present disclosure.

[0100] Referring to FIG. 7, NTN communication can be performed based on a satellite network, HIBS (high-altitude platform stations (HAPS) as international mobile telecommunications (IMT) base stations (BS)), and an aeronautical communication-capable terminal (e.g., AAM). For example, to improve coverage, devices such as a satellite network, HIBS, and an aeronautical communication-capable terminal (e.g., AAM) can act as relays. For example, an AAM can communicate with a base station, a satellite network, etc., and / or an AAM can communicate directly with a terminal, another AAM, etc.

[0101] Transmitting system information (e.g., MIB) in the THz frequency band can be inefficient because, in the case of high frequency bands, beam sweeping must be performed more frequently to cover the entire area of ​​the cell as the beam width becomes narrow. In particular, transmitting system information in this manner can be even more inefficient when there are not many users in the cell. Accordingly, a system information transmission procedure as shown in FIG. 8 below may be used.

[0102] FIG. 8 illustrates a procedure for transmitting system information for THz communication according to one embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure.

[0103] The embodiment of FIG. 8 was created considering a THz situation, but it is also applicable in a 6G communication environment where THz is not applied. In addition, the procedure illustrated in FIG. 8 can be combined with various embodiments of the present disclosure described below. For example, the embodiments described below can be performed based on system information obtained by the procedure illustrated in FIG. 8.

[0104] Referring to FIG. 8, in step S801, the base station (80) can transmit system information of cell #1 through cell #2. For example, the base station (820) provides at least two cells, where cell #1 uses a THz frequency band and cell #2 uses a frequency band other than the THz frequency band. Here, the system information may include at least one of SFN, PDCCH configuration for SIB1, cell barring, cell re-selection, and subcarrier spacing generated at the higher layer, and at least one of SFN, half frame indicator, and SSB index generated at the physical layer. To this end, for example, cell #1 and cell #2 may have a secondary cell and primary cell relationship.

[0105] In step S803, the terminal (810) can obtain synchronization for cell #1. Synchronization can be obtained by detecting a synchronization signal. Generally, synchronization is obtained prior to receiving system information, but since the system information of cell #1 is received in cell #2, synchronization for cell #1 can be obtained after receiving system information. For example, the terminal (810) can obtain synchronization based on system information. However, unlike FIG. 8, according to another example, synchronization acquisition can be performed prior to step S801.

[0106] In step S805, the terminal (810) may transmit a signal to connect to cell #1. For example, the signal may include a random access preamble. The structure of the signal and the resource (e.g., channel) for transmitting the signal may be identified through system information. Subsequently, in step S807, the terminal (810) and the base station (820) may perform a connection procedure to cell #1 and perform communication. In this step, operations according to various embodiments described below may be performed.

[0107] The procedure described with reference to FIG. 8 may be performed when the terminal (801) first connects to cell #1 of the base station (820). Alternatively, a similar procedure may be performed when the terminal (801) handovers to cell #1 of the base station (820). However, in the case of a handover, the system information of cell #1 may be received from a cell of a different base station other than cell #2 of the base station (820).

[0108] The low-power wake-up signal / receiver is described below.

[0109] 5G systems have been designed and developed for both mobile telephony and vertical use cases. In 5G, in addition to latency, reliability, and availability, device energy efficiency can also be critical. Currently, 5G devices may need to be recharged on a weekly or daily basis, depending on an individual's usage time. Typically, 5G devices can consume tens of milliwatts in RRC idle / inactive states and hundreds of milliwatts when RRC connected. Designs that extend battery life can be essential for improving energy efficiency and enhancing the user experience.

[0110] Energy efficiency can be even more critical for devices without a continuous energy source, such as those using small rechargeable and single coin cell batteries. In vertical use cases, sensors and actuators can be widely used for monitoring, measurement, charging, etc. Generally, these batteries cannot be recharged and can be expected to last for at least several years, as described in the technical literature. Wearable devices may include smartwatches, rings, e-health devices, and medical monitoring devices. With typical battery capacities, it may be difficult to last up to 1 to 2 weeks as needed.

[0111] Power consumption may vary depending on the length of the configured weather period, such as the phasing cycle. To meet the battery life requirements mentioned above, a large value of extended discontinuous reception (e.g., eDRX) cycles is used, which is expected to result in longer latency; this may not be suitable for services requiring both long battery life and short latency. For example, in fire detection and extinguishing use cases, fire shutters must close and sprinklers activated by actuators must be activated within 1 to 2 seconds after a fire is detected by a sensor; however, long extended discontinuous reception (e.g., eDRX) cycles cannot meet the latency requirements, so extended discontinuous reception (e.g., eDRX) may not be suitable for use cases where latency is critical.

[0112] Currently, since the terminal must wake up periodically during discontinuous reception (e.g., DRX) cycles, power consumption during periods without signal or data traffic may account for the majority of power consumption. Power consumption could be drastically reduced if the terminal could wake up only when triggered, such as during paging. This can be achieved by using a separate receiver capable of triggering the main radio with a wake-up signal and monitoring the wake-up signal with ultra-low power consumption. The main radio operates for data transmission and reception and can be turned off or set to hibernation mode when not powered on.

[0113] The terms that may be used in this document are as follows.

[0114] - Main Radio (MR): A transmit / receive module operating for NR signals / channels, excluding signals / channels related to low-power weather.

[0115] - Low-power weather receiver (e.g., LP-WUR(LR)): A receiving module that operates to receive / process signals / channels related to low-power weather.

[0116] The following use cases can be considered for low-power weather signals / weather radios (e.g., LP-WUS / WUR):

[0117] - IoT use cases including industrial wireless sensors, controllers, actuators, etc.

[0118] - Examples of wearable devices such as smartwatches, rings, e-health related devices, and medical monitoring devices,

[0119] - eMBB examples including XR / smart glasses, smartphones, etc.

[0120] The following describes technology related to low-power weather signals / weather radios (e.g., LP-WUS / WUR).

[0121] The following investigations can be conducted regarding research on low-power weather signals and receivers for NR.

[0122] - Low-power weather signals and receivers including power saving effects, coverage, system overhead impact, network energy impact, and other related aspects

[0123] - Provision of analysis on receiver architecture, power consumption, noise levels, etc. for low-power weather receivers

[0124] - L1 design and procedure changes required to support low-power weather signal and link performance evaluation

[0125] - Changes to the upper-layer protocols required to support low-power weather signals

[0126] - Related upper-level influence

[0127] It was observed that in RRC idle / active mode, when sufficient relaxation is applied to the main radio (e.g., MR) RRM measurement, significant terminal power saving gains (up to 90% or more) can be obtained by triggering terminal main radio (e.g., MR) paging monitoring using a low-power wake signal / wake radio (e.g., LP-WUS / WUR) compared to the existing idle mode discontinuous reception (e.g., I-DRX) operation (with and without paging early indication (e.g., PEI). Additionally, compared to the existing extended discontinuous reception (e.g., extended DRX; eDRX) operation, if the low-power wake signal (e.g., LP-WUS) monitoring and the corresponding paging monitoring after the main radio (e.g., MR) wake are performed without restriction within the paging time window (e.g., PTW) of the existing extended discontinuous reception (e.g., eDRX), significant reduction in paging latency and moderate terminal power saving gains are observed.

[0128] In RRC connection mode, it was observed that, compared to existing terminal power saving techniques, moderate terminal power saving gains (up to 10% or more) with minimal capacity impact can be obtained by triggering monitoring of the terminal's main radio (e.g., MR) base station-to-terminal physical control channel (e.g., PDCCH) using low-power wake signal / wake radio (e.g., LP-WUS / WUR) in various types of XR traffic and system load scenarios. Additionally, it was observed that significant terminal power saving gains (up to 60% or more) and moderate UPT improvements (up to 10% or more) can be obtained for FTP and IM traffic when the terminal main radio (e.g., MR) is switched to a maximum sleep state during NR low-power wake signal (e.g., LP-WUS) monitoring. Furthermore, in recent research, the feasibility of providing cell RRM measurement offloading from the terminal's main radio (e.g., MR) to the low-power wake receiver (e.g., LP-WUR) has been verified through reasonable evaluation methodologies. In addition, several issues were identified at the upper level that could be further discussed at the WI stage.

[0129] Below, the paging procedure for idle / inactive states in 5G NR is described.

[0130] In 5G NR, if a terminal does not have data transmissions / receptions in progress, the terminal may enter RRC_IDLE or RRC_INACTIVE mode to save power. When base station-to-terminal data (e.g., DL data) for the terminal arrives at the network, the network may send a paging message at a paging occasion (PO) to trigger an RRC setup procedure, an RRC Connection Resume procedure, etc. A paging occasion (e.g., PO) is a set of monitoring times for a physical downlink control channel (e.g., PDCCH) and may consist of multiple time slots (e.g., subframes or OFDM symbols), and at a paging occasion (e.g., PO), base station-to-terminal control information (e.g., downlink control information; DCI) having a CRC scrambled with P-RNTI may be transmitted. For example, the following information may be transmitted by a base station-to-terminal control information (e.g., DCI) format (e.g., DCI format 1_0) having a CRC scrambled with P-RNTI:

[0131] - Short Messages Indicator according to Table 3

[0132] - Short messages according to Table 4. In Table 4, bit 1 is the most significant bit (MSB).

[0133] - Frequency Domain Resource Allocation

[0143] In the present disclosure, a base station-to-terminal physical control channel (e.g., PDCCH) carrying a base station-to-terminal control information (e.g., DCI) format having a CRC scrambled with P-RNTI is referred to as a paging base station-to-terminal physical control channel (e.g., PDCCH), and a base station-to-terminal physical shared channel (e.g., physical downlink shared channel; PDSCH) scheduled by the paging base station-to-terminal physical control channel (e.g., PDCCH) is referred to as a paging base station-to-terminal physical shared channel (e.g., PDSCH). A terminal can decode the paging base station-to-terminal physical shared channel (e.g., PDSCH) based on scheduling information (e.g., frequency domain resource allocation, modulation and coding scheme, etc.) within the paging base station-to-terminal physical control channel (e.g., PDCCH). A paging base station-to-terminal physical shared channel (e.g., PDSCH) carries paging messages, which are used for notification to one or more terminals and may include one or more terminal identifiers (IDs). For example, the paging message and / or fields within the paging message may include information related to a paging record list, lateNonCriticalExtension, nonCriticalExtension, paging group list, terminal identifier associated with the paging record, access type associated with the paging record, paging cause associated with the paging record, TMSI associated with the paging terminal identifier, RNTI associated with the paging terminal identifier, etc.

[0144] The following table provides examples of paging messages and descriptions of the fields within them.

[0145] Description of Paging Record Fields Access Type (accessType) Indicates whether the paging message was generated by a PDU session from a non-3GPP access. Paging Record List (pagingRecordList) If the network contains pagingRecordList-v1700, it contains the same number of entries and is listed in the same order as pagingRecordList (e.g., without suffixes). Paging Cause Indicates whether the paging message was generated by IMS Voice. If this field is present, it may mean that the paging entry is for IMS Voice. If the upper layer supports paging cause and this field is absent but pagingRecordList-v1700 exists, it may mean that the paging entry is for a service other than IMS Voice. Otherwise, the paging cause may not be determined.

[0146] For example, in multi-beam operations, the terminal may assume that the same paging message is repeated in all transmitted beams. The paging message may be the same for both radio access network (RAN) initiation paging and core network (CN) initiation paging.

[0147] A paging frame (PF) is a radio frame and may include one or more paging times (e.g., PO)(s) or a starting point of a paging time (e.g., PO).

[0148] For example, the terminal can monitor one paging time (e.g., PO) per discontinuous reception (e.g., DRX) cycle. The paging frame (e.g., PF) and paging time (e.g., PO) for paging can be determined by predefined formulas.

[0149] For example, in some implementations, the system frame number (SFN) for a paging frame (e.g., PF) may be determined by (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N), and an index i_s indicating the index of a paging time (e.g., PO) may be determined by i_s = floor(UE_ID) mod Ns, where T is a terminal discontinuous reception (e.g., DRX) cycle and is determined by the minimum value of terminal-specific discontinuous reception (e.g., DRX) value(s) and / or default discontinuous reception (e.g., DRX) value broadcast as system information, N is the total number of paging frames in T, Ns is the number of paging times for a paging frame (e.g., PF), PF_offset is the offset used for determining the paging frame (e.g., PF), and UE_ID may be a value determined based on 5G-S-TMSI.

[0150] For example, parameters Ns regarding the number of paging times per paging frame, parameters nAndPagingFrameOffset used to derive the total number of paging frames in T, parameters nrofPDCCH-MonitoringOccasionsPerSSB-InPO regarding the number of base station-to-terminal physical control channel (e.g., PDCCH) monitoring times corresponding to SSBs in paging times, and the length of the default discontinuous reception (e.g., DRX) cycle may be signaled by SIB1, and the values ​​of N and PF_offset may be derived from the parameters nAndPagingFrameOffset.

[0151] For example, base station-to-terminal physical control channel (e.g., PDCCH) monitoring times for paging can be determined based on the parameter firstPDCCH-MonitoringOccasionOfPO, which indicates the first base station-to-terminal physical control channel (e.g., PDCCH) monitoring time for paging of each paging time (e.g., PO) of a paging frame (e.g., PF), and the parameter nrofPDCCH-MonitoringOccasionsPerSSB-InPO.

[0152] For example, the parameter firstPDCCH-MonitoringOccasionOfPO may be signaled by SIB1 for paging in the initial base station-to-terminal communication (e.g., DL link) part bandwidth (e.g., bandwidth part; BWP), and may be signaled by the corresponding part bandwidth (e.g., BWP) setting for paging in a base station-to-terminal part bandwidth (e.g., DL BWP) other than the initial base station-to-terminal communication (e.g., DL link) part bandwidth (e.g., BWP).

[0153] For example, to reduce power consumption, a terminal may use Paging Early Indication (e.g., PEI) in the RRC_IDLE and RRC_INACTIVE states. If a Paging Early Indication (e.g., PEI) setting is provided in the system information, a terminal in the RRC_IDLE or RRC_INACTIVE state that supports Paging Early Indication (e.g., PEI) may monitor Paging Early Indication (e.g., PEI) using the Paging Early Indication (e.g., PEI) parameters within the system information. The terminal monitors one Paging Early Indication (e.g., PEI) per discontinuous reception (e.g., DRX) cycle. A Paging Early Indication occurrence (e.g., PEI-occasion; PEI-O) is a set of base station-to-terminal physical control channel (e.g., PDCCH) monitoring occurrences and may consist of multiple time slots (e.g., subframes or OFDM symbols) in which the Paging Early Indication (e.g., PEI) can be sent.

[0154] For example, in multi-beam operations, the terminal may assume that the same paging early indication (e.g., PEI) is repeated in all transmitted beams. The time position of the paging early indication time (e.g., PEI-O) relative to the terminal's paging time (e.g., PO) may be determined by a reference point and an offset, said reference point being the start of a reference frame determined by a frame-level offset from the start of the first paging frame (e.g., PF)(s) associated with said paging early indication time (e.g., PEI-O), provided by pei-FrameOffset in SIB1, and said offset being a symbol-level offset from said reference point to the start of the first base station-to-terminal physical control channel (e.g., PDCCH) monitoring time of said paging early indication time (e.g., PEI-O), provided by firstPDCCH-MonitoringOccasionOfPEI-O in SIB1.

[0155] For example, if a single paging early indication time (e.g., PEI-O) is associated with the paging times (e.g., PO) of two paging frames (e.g., PF), said two paging frames (e.g., PF) may be consecutive paging frames (e.g., PF) calculated by the parameters PF_offset, T, Ns, and N. For more details regarding paging early indications (e.g., PEI), refer to the technical literature.

[0156] According to one embodiment of the present disclosure, a paging discontinuous reception (e.g., DRX) may be defined in which a terminal that is RRC_IDLE or RRC_INACTIVE is required to monitor paging channels for only one paging time (e.g., PO) per discontinuous reception (e.g., DRX) cycle. For example, the following paging discontinuous reception (e.g., DRX) cycles may be set by a network:

[0157] i) For core network initiated paging (CN-initiated paging), a default cycle is broadcast with system information, and

[0158] ii) For CN-initial paging, terminal-specific cycles can be established via non-access stratum (NAS) signaling, and

[0159] iii) For radio access network (RAN)-initiated paging, terminal-specific cycles can be established via RRC signaling.

[0160] For example, a terminal may use the shortest of the applicable discontinuous reception (e.g., DRX) cycles. For example, a terminal that is RRC_IDLE may use the shorter of the first two discontinuous reception (e.g., DRX) cycles among the three discontinuous reception (e.g., DRX) cycles, and a terminal that is RRC_INACTIVE may use the shortest of the three discontinuous reception (e.g., DRX) cycles.

[0161] The operation sequence of the terminal and the signaling operation between the base station and the terminal are described below.

[0162] FIG. 9 illustrates a flowchart of the operation of a terminal performing one or more physical channels / signal transmissions to which the method proposed in the present disclosure may be applied, according to one embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure.

[0163] Referring to FIG. 9(a), a flowchart is shown of a terminal performing terminal-to-base station data transmission. For example, the terminal may receive terminal-to-base station data / channel related information. Subsequently, the terminal may receive base station-to-terminal control information for terminal-to-base station data transmission, or receive information for terminal-to-base station channel transmission. Subsequently, for example, the terminal may transmit terminal-to-base station data / channel.

[0164] At this point, for example, the terminal can check whether all the instructed data / channels have been transmitted, and if not all have been transmitted, it can perform terminal-to-base station data / channel transmission (again and / or additionally). If all have been transmitted, the above procedure may be terminated.

[0165] Referring to FIG. 9(b), a flowchart is shown of a terminal performing base station-to-terminal data reception. For example, the terminal may receive information related to base station-to-terminal data / channel. Subsequently, the terminal may receive base station-to-terminal control information for base station-to-terminal data reception, or receive information for base station-to-terminal channel reception. Subsequently, for example, the terminal may receive base station-to-terminal data / channel.

[0166] At this time, for example, the terminal can check whether all the instructed data / channels have been received, and if not all have been received, it can perform base station-to-terminal data / channel reception (again and / or additionally).

For example, in an NR system, four quasi-co-location (e.g., QCL) types are defined as follows: 'typeA': {Doppler shift, Doppler spread, average delay, delay spread}, 'typeB': {Doppler shift, Doppler spread}, 'typeC': {Doppler shift, average delay}, 'typeD': {spatial Rx parameters}. For example, for a specific base station-to-terminal reference signal antenna port(s), a first base station-to-terminal reference signal (e.g., DL RS) may be set as a reference to a similar identical location (e.g., QCL) type X (X=A, B, C, or D), and additionally, a second base station-to-terminal reference signal (e.g., DL RS) may be set as a reference to a similar identical location (e.g., QCL) type Y (Y=A, B, C, or D, but X).

For transmission setting indicators among the fields in base station-to-terminal control information (e.g., DCI) that schedule a base station-to-terminal physical shared channel (e.g., PDSCH), the transmission setting indicator (e.g., TCI) state index corresponding to each code point constituting the field is activated by MAC CE, and the transmission setting indicator (e.g., TCI) state setting for each transmission setting indicator (e.g., TCI) state index can be set through RRC signaling. In an NR system, the transmission setting indicator (e.g., TCI) state is set between the base station-to-terminal reference signal (e.g., DL RS), but setting between the base station-to-terminal reference signal (e.g., DL RS) and the terminal-to-base station reference signal (e.g., UL RS), or between the terminal-to-base station reference signal (e.g., UL RS) and the terminal-to-base station reference signal (e.g., UL RS) may be allowed in the future. For example, examples of terminal-to-base station reference signals (e.g., UL RS) may include sounding reference signals (e.g., SRS), terminal-to-base station physical shared channel (e.g., PUSCH) decoding reference signals (e.g., DM-RS), terminal-to-base station physical control channel (e.g., PUCCH) decoding reference signals (e.g., DM-RS).

[0273] SRI (SRS resource indicator): A sounding reference signal (e.g., SRS) resource indicator. Among the fields in base station-to-terminal control information (e.g., DCI) that schedules a terminal-to-base station physical shared channel (e.g., PUSCH), one of the sounding reference signal (e.g., SRS) resource index values ​​set in the sounding reference signal (e.g., SRS) resource indicator may be indicated. When transmitting a terminal-to-base station physical shared channel (e.g., PUSCH), the terminal may transmit the terminal-to-base station physical shared channel (e.g., PUSCH) by utilizing the same spatial domain transmission filter used for reference signal transmission and reception associated with the corresponding sounding reference signal (e.g., SRS) resource. At this time, for each sounding reference signal (e.g., SRS) resource, the reference signal (e.g., RS) is set by RRC signaling through the SRS-SpatialRelationInfo parameter, and a synchronization signal / physical broadcasting channel (e.g., SS / PBCH) block, channel status reference signal (e.g., CSI-RS), or sounding reference signal (e.g., SRS) can be set as the reference signal (e.g., RS).

[0274] LO(LP-WUS occasion): Low-power weather signal opportunity. For example, it may consist of one or more LP-WUS monitoring opportunities.

[0275] LMO: LP-WUS Monitoring Opportunity

[0276] In conventional technology, the wake-up delay capability of a User Equipment (UE) has been reported in various ways, and these methods may be as follows.

[0277] (Conventional 1) Fixed delay time reporting method

[0278] For example, the terminal can report one of three fixed wake-up delay values ​​{80ms, 500ms, 900ms}. This method can be implemented under the following assumptions.

[0279] - Synchronization signal block (e.g., SSB) period: 20ms

[0280] - 80ms: 3 synchronization signal blocks (e.g., SSB) are required for synchronization.

[0281] - 500ms, 900ms: 5 synchronization signal blocks (e.g., SSB) are required for synchronization, respectively.

[0282] For example, in this case, there may be a limitation in scalability because various configured synchronization signal block (e.g., SSB) periods cannot be considered.

[0283] (Conventional 2) Dual parameter reporting method

[0284] For example, the terminal can report the main radio (e.g., MR; Main Radio) activation time and the number of required synchronization signal blocks (e.g., SSB) in pairs.

[0285] - (20ms, 3 synchronization signal blocks (e.g., SSB))

[0286] - (400ms, 5 synchronization signal blocks (e.g., SSB))

[0287] - (800ms, 5 synchronization signal blocks (e.g., SSB))

[0288] For example, in this case, there may be limitations in that the correlation between parameters is not sufficiently considered.

[0289] (Conventional 3) Main radio (e.g., MR) activation time-based method

[0290] For example, instead of the weather delay, the activation time of the main radio (e.g., MR) may be reported.

[0291] - Activation time values: {20ms, 400ms, 800ms}

[0292] - The number of synchronization signal blocks (e.g., SSB) for synchronization for each activation time can be predefined:

[0293] -- 20ms: Requires 3 synchronization signal blocks (e.g., SSB).

[0294] -- 400ms, 800ms: 5 synchronization signal blocks (e.g., SSB) required each

[0295] For example, in this case, there may be limitations in that synchronization performance in an actual network environment is not accurately reflected.

[0296] For example, the limitations of conventional technology may be as follows.

[0297] For example, according to conventional technology, there may be limitations regarding the dependency of the synchronization signal block (e.g., SSB) period. For example, only a fixed synchronization signal block (e.g., SSB) period (usually 20ms) may be assumed, and various synchronization signal block (e.g., SSB) periods may not be considered.

[0298] For example, according to conventional technology, the reflection of synchronization performance may be insufficient. For instance, variability due to the reception quality of synchronization signal blocks (e.g., SSB) may not be considered, and it may be difficult to reflect performance variations in the network environment.

[0299] For example, according to conventional technology, problems regarding implementation complexity may arise. For instance, according to conventional technology, signaling between the network and the terminal is complex, and there may be a lack of flexibility to respond to dynamic environments.

[0300] Due to the limitations mentioned above, it has been difficult to effectively operate low-power wake signals (e.g., LP-WUS) in actual implementations. To address this problem, the present disclosure may have the following objectives.

[0301] - Proposing a dynamic wake-up delay adjustment mechanism based on the cell's synchronization signal block (e.g., SSB) period to efficiently process various synchronization signal block (e.g., SSB) periods, and / or optimizing the start and end times of low-power wake-up signal (e.g., LP-WUS) monitoring by defining entry / exit conditions based on the reception quality of the synchronization signal block (e.g., SSB).

[0302] Through this, according to the present disclosure, the following effects may occur.

[0303] For example, according to the present disclosure, the reliability of receiving a low-power weather signal (e.g., LP-WUS) can be improved based on the calculation of a weather delay that takes into account the actual operating environment of the terminal.

[0304] For example, according to the present disclosure, efficient system operation can be made possible by minimizing unnecessary power consumption.

[0305] For example, according to the present disclosure, through dynamic offset adjustment based on a representative synchronization signal block (e.g., SSB) period value, it is possible to respond to various synchronization signal block (e.g., SSB) settings while enabling numerous terminal capabilities to be managed efficiently without fragmentation.

[0306] In the following disclosure, examples are provided based on an NR system to explain the principles of the disclosure, but the proposed methods are not limited to a specific transmission and reception form of NR unless otherwise stated.

[0307] In addition, the present disclosure below explains the principles of disclosure by providing examples based on the characteristics and structure of a terminal for discontinuous reception (e.g., DRX), but the proposed methods are not limited to supporting terminals for discontinuous reception (e.g., DRX) unless otherwise stated.

[0308] Therefore, it is obvious that the methods proposed in this disclosure can be applied to all wireless communication transmission and reception structures and services without further explanation, provided that the principles of the disclosure are not compromised.

[0309] For example, by using the proposed method, the terminal and the base station can perform the following operations.

[0310] 1. Reception of a system information block (e.g., SIB) by the terminal: The terminal may receive a system information block (e.g., SIB) from the base station. This system information block (e.g., SIB) may include the base station's synchronization signal block (e.g., SSB) period information and / or a low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset).

[0311] 2. Checking the synchronization signal block (e.g., SSB) period: The terminal can check the synchronization signal block (e.g., SSB) period of the base station by analyzing the received system information block (e.g., SIB). For example, it is assumed here that the synchronization signal block (e.g., SSB) period is set to 10ms.

[0312] 3. Calculation of wake-up delay: The terminal can calculate the wake-up delay based on the period of the synchronization signal block (e.g., SSB). For example, if the period of the synchronization signal block (e.g., SSB) is 10ms, the terminal can determine the wake-up delay by assuming the application of 20ms. For example, instead of the wake-up delay for the synchronization signal block (e.g., SBB) period of 10ms in the predefined table, the wake-up delay can be determined by applying 20ms, which is the representative value for the synchronization signal block (e.g., SBB) period of 10ms, to the predefined table.

[0313] 4. Determination of low-power wake-up signal (e.g., LP-WUS) availability: The terminal can determine the availability of a low-power wake-up signal (e.g., LP-WUS) by comparing a set low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset) with a calculated wake-up delay. For example, if the low-power wake-up signal (e.g., LP-WUS) is not available, the terminal may select another paging opportunity (e.g., PO) or use a method of receiving a paging opportunity (e.g., PO) / paging early indication (e.g., PEI) at each existing paging cycle.

[0314] 5. Waiting for low-power wake-up signal (e.g., LP-WUS): The terminal may wait to receive a low-power wake-up signal (e.g., LP-WUS). At this time, the base station may transmit a low-power wake-up signal (e.g., LP-WUS).

[0315] 6. Reception of low-power wake-up signal (e.g., LP-WUS): The terminal can receive a low-power wake-up signal (e.g., LP-WUS) transmitted from the base station. This allows the terminal to update the status of the base station and necessary information.

[0316] In the following description, the distinction between each method or option is intended to clarify the explanation and is not to be interpreted restrictively as meaning that each must necessarily be implemented as an independent disclosure. For example, while the methods / options described below may each be implemented individually, they may also be implemented in a combined form in which at least some parts are combined, provided that they do not conflict with one another.

[0317] According to various embodiments of the present disclosure, the timing of reception of a low-power wake-up signal (e.g., LP-WUS) may be determined based on system information transmitted by a base station or separately described in each of the proposed methods below. For example, if the low-power wake-up signal (e.g., LP-WUS) can be received as 1-bit information in a single unit (e.g., 1 slot or 1 symbol) through on / off keying, the offset value and period on the system frame may simply be set. If, for reliability, decoded information is received through multiple on / off keyings or 2 or more bit information is received, the time interval during which the terminal receives the low-power wake-up signal (e.g., LP-WUS) and the terminal ID for the low-power wake-up signal receiver (e.g., LP-WUR) for verification after receiving the low-power wake-up signal (e.g., LP-WUS) may be determined based on this, similar to a paging early indication (e.g., PEI). For example, in this case, the terminal ID used for conventional paging reception may be reused.

[0318] According to one embodiment of the present disclosure, a method may be considered in which a terminal derives the reception location of a low-power wake-up signal (e.g., LP-WUS) through a terminal ID given to the terminal for receiving a low-power wake-up signal (e.g., LP-WUS). For example, the low-power wake-up signal (e.g., LP-WUS) is repeated at short intervals, and the base station may provide the terminal with the number of low-power wake-up signal (e.g., LP-WUS) subgroup parameters. This refers to the number of low-power wake-up signal monitoring periods (e.g., LP-WUS MO) required for one terminal subgroup, in other words, the low-power wake-up signal (e.g., LP-WUS) for one terminal subgroup may be repeated for each corresponding low-power wake-up signal monitoring period (e.g., LP-WUS MO).

[0319] For example, a terminal can distinguish the low-power wake-up signal monitoring time (e.g., LP-WUS MO) to be monitored among the monitoring times (e.g., MO) equal to the number of low-power wake-up signal (e.g., LP-WUS) subgroups through a terminal ID given to it. In addition, for example, if K (K>2) bits of information are received through the monitoring of the low-power wake-up signal (e.g., LP-WUS), the reception of the low-power wake-up signal (e.g., LP-WUS) can also be distinguished through the terminal ID.

[0320] According to one embodiment of the present disclosure, [Method #1], a method for handling various synchronization signal block (e.g., SSB) periods may be provided.

[0321] The synchronization signal block (e.g., SSB) period setting of a conventional base station may be configured with various periods of 5ms, 10ms, 20ms, 40ms, 80ms, and / or 160ms. According to one embodiment of the present disclosure, in order to efficiently handle these various synchronization signal block (e.g., SSB) periods, a method is proposed to calculate a wake-up delay by dividing the assumption of a synchronization signal block (e.g., SSB) period fixed at 20ms into two or more values ​​(e.g., 20ms and 80ms) and applying the value closer to the two values ​​based on the synchronization signal block (e.g., SSB) period information received by the terminal.

[0322] For example, the wake-up delay can be calculated by assuming an application of 20ms when the period of a synchronization signal block (e.g., SSB) received from a base station is 10ms, and by assuming an application of 80ms when the period of a synchronization signal block (e.g., SSB) received from a base station is 160ms. Through this, the terminal can respond more flexibly to various synchronization signal block (e.g., SSB) period settings, and the accuracy of the wake-up delay calculation can be improved. According to this method, by considering the variability of the synchronization signal block (e.g., SSB) period, the synchronization performance of the terminal can be optimized, and performance degradation due to changes in the network environment can be minimized.

[0323] For example, the method of selecting the period assumption (or assumed period) in a given synchronization signal block (e.g., SSB) period may be as follows.

[0324] 1. Method for selecting the nearest period assumption (or assumed period).

[0325] For example, the assumption value closest to the period of the synchronization signal block (e.g., SSB) received by the terminal may be selected. For example, if the period of the synchronization signal block (e.g., SSB) received from the base station is 10ms, 20ms may be assumed to be applied, and if the period of the synchronization signal block (e.g., SSB) received from the base station is 160ms, 80ms may be assumed to be applied.

[0326] 2. Upper / Lower Limit Selection Method

[0327] For example, an upper or lower assumption value may be selected when the period of a synchronization signal block (e.g., SSB) received by the terminal exceeds or falls below a specific reference value. For example, if the period of a synchronization signal block (e.g., SSB) received from the base station is 50ms or less, 20ms may be assumed to be applied, and if the period of a synchronization signal block (e.g., SSB) received from the base station exceeds 50ms, 80ms may be assumed to be applied.

[0328] For example, the reference value may be a predetermined value or may be indicated / set by the base station's L1 signaling or upper layer signaling.

[0329] 3. Pre-definition method

[0330] For example, a representative period for calculating the weather delay can be predefined for each synchronization signal block (e.g., SSB) period description configurable to the base station.

[0331] For example, if a synchronization signal block (e.g., SSB) period of 5ms, 10ms, 20ms, and / or 40ms is set, 20ms may be selected as the assumed period (or assumed period). If a synchronization signal block (e.g., SSB) period of 80ms and / or 160ms is set, 80ms may be selected as the assumed period.

[0332] This allows the terminal to respond more flexibly to various synchronization signal block (e.g., SSB) period settings, and improves the accuracy of estimating wake delays. By considering the variability of synchronization signal block (e.g., SSB) periods through this method, the synchronization performance of the terminal is optimized, and performance degradation due to changes in the network environment can be minimized.

[0333] FIG. 12 shows a synchronization signal (e.g., SSB) period and wake delay correspondence table to which a representative synchronization signal (e.g., SSB) period is applied, according to one embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure, and the description, function, procedure, proposal, method, and / or operation of said embodiment may be omitted.

[0334] Referring to FIG. 12, a table showing the wake-up delay of a terminal according to the synchronization signal (e.g., SSB) period and terminal capability is shown (left table). For example, the columns showing 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms from the top may represent the synchronization signal (e.g., SSB) period, and the rows showing 0, 1, and 2 from the left may be indices representing the capability of the terminal according to the synchronization signal (e.g., SSB) period.

[0335] For example, according to various embodiments of the present disclosure, a representative synchronization signal (e.g., SSB) period may be applied to the table on the left to form the table on the right, and the wake-up delay of the terminal may be determined based on the table on the right. For example, in the present embodiment, for a synchronization signal (e.g., SSB) period of 20ms or less, it is assumed that the representative synchronization signal (e.g., SSB) period is 20ms.

[0336] At this time, since the 20ms synchronization signal (e.g., SSB) period is representative for the 20ms, 10ms, and 5ms synchronization signal (e.g., SSB) periods, the capability for the 20ms synchronization signal (e.g., SSB) period of the terminal can be applied for the 20ms, 10ms, and 5ms synchronization signal (e.g., SSB) periods.

[0337] For example, if the synchronization signal (e.g., SSB) period indicated by a system information block (e.g., SIB) received from a base station is 10ms, the terminal can determine its wake-up delay to be 500ms regardless of the index of the capability for the 10ms synchronization signal (e.g., SSB) period when the index of the capability for its 20ms synchronization signal (e.g., SSB) period is 1.

[0338] In order to determine the wake-up delay of the terminal in the selected period assumption (or assumed period) as described above, the terminal may report the wake-up delay capability for each period assumption (or assumed period) (to the base station). For example, in the conventional fixed delay time reporting method, the terminal reports one of three fixed wake-up delay values ​​{80ms, 500ms, 900ms}, whereas in the proposed method, two period assumptions (or assumed periods) are considered, and a pair of fixed wake-up delay values ​​in each period assumption (or assumed period) may be reported. For example, considering period assumptions (or assumed periods) of 20ms and 80ms, the terminal may report one of the following three pairs of fixed wake-up delay values.

[0339] {(80, 220), (500, 800), (900, 1200)}

[0340] Alternatively, for example, if the synchronization signal block (e.g., SSB) period is long, a smaller number of synchronization signal blocks (e.g., SSB) of 2 or 3 may be considered, and in this case, a wake delay pair with a different number of synchronization signal blocks (e.g., SSB) may be considered.

[0341] {(80, 140), (500, 640), (900, 1040)}

[0342] A similar method may be considered in the dual parameter reporting method and the main radio (e.g., MR) activation time-based method described above. For example, when multiple synchronization signal block (e.g., SSB) period assumptions (or assumed periods) are given, the number of synchronization signal block (e.g., SSB) receptions required for each period assumption (or assumed period) may be set or defined.

[0343] For example, in a dual parameter reporting method, a set of parameters consisting of a main radio (e.g., MR) activation time, the number of times a synchronization signal block (e.g., SSB) needs to be received in a short period assumption (or assumed period), and the number of times a synchronization signal block (e.g., SSB) needs to be received in a long period assumption (or assumed period) may be reported, such as (400ms, 5 synchronization signal blocks (e.g., SSB), 3 synchronization signal blocks (e.g., SSB)). In a main radio (e.g., MR) activation time-based method, the number of times a synchronization signal block (e.g., SSB) needs to be received in each period assumption (or assumed period) may also be defined.

[0344] For example, a terminal may support only a specific period assumption (or assumed period). The terminal may separately report to the base station the period assumption (or assumed period) it can support, or report a wake-up delay only for the supported period assumption (or assumed period). Alternatively, for example, the terminal may base its period assumption (or assumed period) on 20ms and report (to the base station) its terminal capability regarding whether it supports a different value of period assumption (or assumed period) (e.g., 80ms). For example, a terminal supporting a different value of period assumption (or assumed period) may additionally report a wake-up delay in accordance with the method described in the present proposal in addition to the wake-up delay of the base period assumption (or assumed period), or report a wake-up delay that replaces the wake-up delay of the base period assumption (or assumed period).

[0345] For example, a period assumption (or assumed period) may be given for all configurable periods. In such cases, it is evident that the terminal can always have a period assumption (or assumed period) for the configured synchronization signal block (e.g., SSB) period and can apply that value.

[0346] According to one embodiment of the present disclosure [Method #1-1], terminal capability reporting for various synchronization signal block (e.g., SSB) cycles may be proposed.

[0347] For example, the present disclosure proposes a method in which a base station receives weather delay information from a terminal by utilizing an index of a predefined table instead of directly using a synchronization signal block (e.g., SSB) period. This can contribute to reducing complexity and minimizing overhead. According to the present method, weather delay information can be determined by the following procedure.

[0348] 1. Table Definition

[0349] For example, a table index (or index value) and its corresponding wake delay value can be assigned based on the period range of a synchronization signal block (e.g., SSB). It can be configured as shown in the table below:

[0350] Synchronization signal block (e.g., SSB) Period Index = 0 (Low) Index = 1 (Middle) Index = 2 (High) 5 ms25 ms425 ms825 ms10 ms40 ms550 ms950 ms20 ms70 ms500 ms900 ms40 ms130 ms600 ms1000 ms80 ms250 ms800 ms1200 ms160 ms490 ms1200 ms1600 ms

[0351] For example, the weather delay value for each index can be adjusted for terminal capability and system optimization.

[0352] 2. Terminal Report

[0353] For example, the terminal may report a table index (or index value) based on the terminal's capability. For example, the terminal may report one of the values ​​0, 1, and 2 (for each synchronization signal block (e.g., SSB) cycle).

[0354] 3. Calculation of weather delay

[0355] For example, the terminal may select one of the defined wake-up delay values ​​based on the table index (or index value) it reports, based on the synchronization signal block (e.g., SSB) period received (from the base station). For example, if the terminal reports index = 1 and the synchronization signal block (e.g., SSB) period (received from the base station) is 40 ms, the wake-up delay may be determined to be 600 ms.

[0356] For example, a base station can also calculate a wake-up delay by applying a predefined wake-up delay value based on a table index (or index value) received from a terminal and a synchronization signal block (e.g., SSB) period set by itself.

[0357] According to the present proposal, signaling overhead can be reduced by transmitting shorter table index information rather than transmitting the wake-up delay itself for each period of all configurable synchronization signal blocks (e.g., SSB).

[0358] FIG. 13 illustrates a form in which a terminal reports its capability regarding its weather delay to a base station, according to one embodiment of the present disclosure. The embodiment of FIG. 13 may be combined with various embodiments of the present disclosure, and the description, function, procedure, proposal, method, and / or operation of said embodiment may be omitted.

[0359] Referring to FIG. 13, a table is shown indicating the wake-up delay of a terminal according to the synchronization signal (e.g., SSB) period and terminal capability. The columns showing 20ms, 40ms, 80ms, and 160ms from the top may represent the synchronization signal (e.g., SSB) period, and the rows showing 0, 1, and 2 from the left may be indices representing the capability of the terminal according to the synchronization signal (e.g., SSB) period.

[0360] For example, according to various embodiments of the present disclosure, the capability of a terminal for a synchronization signal (e.g., SSB) period of less than 20ms may be represented by the capability of a terminal for a synchronization signal (e.g., SBB) period of 20ms. For example, even if the synchronization signal (e.g., SSB) period transmitted through a system information block (e.g., SIB) transmitted from a base station to a terminal is 10ms, the waking delay of the terminal may be determined based on the capability of the terminal for a synchronization signal (e.g., SSB) period of 20ms in the table above.

[0361] Here, for example, the terminal may report to the base station its capabilities regarding wake-up delay per synchronization signal (e.g., SSB) cycle. For example, when the terminal can accommodate a wake-up delay of 70ms in a 20ms synchronization signal (e.g., SSB) cycle, a wake-up delay of 600ms in a 40ms synchronization signal (e.g., SSB) cycle, a wake-up delay of 800ms in an 80ms synchronization signal (e.g., SSB) cycle, and a wake-up delay of 1600ms in a 160ms synchronization signal (e.g., SSB) cycle, the terminal may report to the base station an index {0, 1, 1, 2} for each synchronization signal (e.g., SSB) cycle based on the table in FIG. 13.

[0362] According to one embodiment of the present disclosure [Method #2], an entry / exit condition based on the period of a synchronization signal block (e.g., SSB) may be provided.

[0363] Methods have been proposed to compare a wake-up delay with a set low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset) in order for a terminal to determine the availability of a low-power wake-up signal (e.g., LP-WUS).

[0364] If the actual wake-up time of the terminal is determined by the synchronization signal block (e.g., SSB) period, and if the low-power wake-up signal (e.g., LP-WUS) receiver is designed based on a specific synchronization signal block (e.g., SSB) period, the terminal can compare the synchronization signal block (e.g., SSB) period and / or a supported wake-up delay with a set low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset) and determine the availability of the low-power wake-up signal (e.g., LP-WUS) at that offset, and if the low-power wake-up signal (e.g., LP-WUS) is not available at that offset, it can select another paging opportunity (e.g., PO) (e.g., next paging opportunity (e.g., PO)) or use a method of continuously receiving paging opportunities (e.g., PO) / paging early indications (e.g., PEI) at every paging period as in the conventional method, rather than monitoring paging opportunities (e.g., PO) based on the low-power wake-up signal (e.g., LP-WUS).

[0365] For example, the terminal may use the following method to compare the synchronization signal block (e.g., SSB) period and / or the supported wake-up delay with the set low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset) and to determine the availability of the low-power wake-up signal (e.g., LP-WUS).

[0366] - Weather delay-based method (conventional method)

[0367] The terminal can compare the supported wake-up delay it reported with the low-power wake-up opportunity-to-paging opportunity offset (e.g., LP-to-PO offset) set by the network. If the wake-up delay is within the low-power wake-up opportunity-to-paging opportunity offset (e.g., LP-to-PO offset), the terminal can determine that the low-power wake-up signal (e.g., LP-WUS) is available. More specifically, the terminal determines that the low-power wake-up signal (e.g., LP-WUS) is available if the wake-up delay is smaller than the time interval between the end of the last low-power wake-up monitoring opportunity (e.g., LMO) within the low-power wake-up opportunity (e.g., LO) requiring reception and the start of the target paging opportunity (e.g., PO) or paging frame (e.g., PF).

[0368] FIG. 14 illustrates the calculation of wake delay based on a synchronization signal (e.g., SSB) period and a terminal capability index, and the determination of low-power wake signal (e.g., LP-WUS) availability based on a low-power wake signal opportunity-paging opportunity offset (e.g., LO-PO offset), according to one embodiment of the present disclosure. The embodiment of FIG. 14 may be combined with various embodiments of the present disclosure, and the description, function, procedure, proposal, method, and / or operation of said embodiment may be omitted.

[0369] Referring to FIG. 14, a table is shown indicating the wake-up delay of a terminal according to the synchronization signal (e.g., SSB) period and terminal capability. The columns showing 20ms, 40ms, 80ms, and 160ms from the top may represent the synchronization signal (e.g., SSB) period, and the rows showing 0, 1, and 2 from the left may be indices representing the capability of the terminal according to the synchronization signal (e.g., SSB) period.

[0370] For example, according to various embodiments of the present disclosure, the capability of a terminal for a synchronization signal (e.g., SSB) period of less than 20ms may be represented by the capability of a terminal for a synchronization signal (e.g., SBB) period of 20ms. For example, even if the synchronization signal (e.g., SSB) period transmitted through a system information block (e.g., SIB) transmitted from a base station to a terminal is 10ms, the waking delay of the terminal may be determined based on the capability of the terminal for a synchronization signal (e.g., SSB) period of 20ms in the table above.

[0371] Here, for example, the terminal can report to the base station its capabilities related to wake-up delay per synchronization signal (e.g., SSB) cycle. For example, when the terminal can accommodate a wake-up delay of 70ms in a 20ms synchronization signal (e.g., SSB) cycle, a wake-up delay of 600ms in a 40ms synchronization signal (e.g., SSB) cycle, a wake-up delay of 800ms in an 80ms synchronization signal (e.g., SSB) cycle, and a wake-up delay of 1600ms in a 160ms synchronization signal (e.g., SSB) cycle, the terminal can report to the base station an index {0, 1, 1, 2} for each synchronization signal (e.g., SSB) cycle based on the table in FIG. 14.

[0372] At this time, the terminal can receive information about the synchronization signal (e.g., SSB) period and information about the low-power wake-up signal opportunity-paging opportunity offset (e.g., LO-PO offset) from the base station through a system information block (e.g., SIB).

[0373] For example, the terminal may determine its wake-up delay to be 600ms based on the synchronization signal (e.g., SSB) period (e.g., 40ms) and its terminal capability index (index 1 at 40ms). At this time, since the low-power wake-up signal opportunity-paging opportunity offset (e.g., LO-PO offset) received from the base station is smaller than the terminal's wake-up delay ("not smaller"), the terminal may not perform a low-power wake-up signal (e.g., LP-WUS) reception operation and may perform a normal paging operation according to the existing technology.

[0374] - Synchronization signal block (e.g., SSB) period-based method

[0375] For example, the terminal can check the period of the synchronization signal block (e.g., SSB) currently in use on the network. For example, the terminal can check whether the period of the synchronization signal block (e.g., SSB) is compatible with the terminal's wake-up delay and determine the availability of the low-power wake-up signal (e.g., LP-WUS).

[0376] For example, a compatible synchronization signal block (e.g., SSB) period can be determined in advance. For example, if 20ms is determined as a compatible period, and for other synchronization signal block (e.g., SSB) periods or larger synchronization signal block (e.g., SSB) periods, the terminal may assume that the low-power wake-up signal (e.g., LP-WUS) is not used and may use a method of continuously receiving paging opportunities (e.g., PO) / paging early indications (e.g., PEI) at every paging period as in the conventional method, rather than monitoring paging opportunities (e.g., PO) based on the low-power wake-up signal (e.g., LP-WUS).

[0377] For example, the compatible synchronization signal block (e.g., SSB) period may vary from terminal to terminal. The terminal may report the compatible synchronization signal block (e.g., SSB) period or determine the compatible synchronization signal block (e.g., SSB) period based on the period assumption (or assumed period) of Method #1. For example, the terminal may report its compatible synchronization signal block (e.g., SSB) period and begin receiving a paging opportunity (e.g., PO) based on a low-power wake-up signal (e.g., LP-WUS) only when the corresponding synchronization signal block (e.g., SSB) period is set. For example, in the present disclosure, monitoring of a paging opportunity (e.g., PO) may include receiving a paging opportunity (e.g., PO).

[0378] For example, a terminal may determine that a synchronization signal block (e.g., SSB) period smaller than a compatible synchronization signal block (e.g., SSB) period is also compatible. For example, a terminal that supports a synchronization signal block (e.g., SSB) period of 20ms for receiving a low-power wake-up signal (e.g., LP-WUS) may be determined to also support synchronization signal block (e.g., SSB) periods of 5ms and 10ms.

[0379] For example, a terminal reporting a wake-up delay corresponding to a synchronization signal block (e.g., SSB) period assumption (or assumed period) of 20ms can be assumed to be able to receive a low-power wake-up signal (e.g., LP-WUS) only during a synchronization signal block (e.g., SSB) period associated with 20ms. More specifically, among the configurable synchronization signal block (e.g., SSB) periods, 5ms, 10ms, 20ms, and 40ms are assumed to have a period of 20ms (or assumed period), and 80ms and 160ms are assumed to have a period of 80ms (or assumed period). A terminal supporting a period assumption (or assumed period) of 20ms can be determined to be able to receive a low-power wake-up signal (e.g., LP-WUS) only when a synchronization signal block (e.g., SSB) period corresponding to a period assumption (or assumed period) of 20ms is set.

[0380] According to one embodiment of the present disclosure, a method may be provided to comprehensively consider the synchronization signal block (e.g., SSB) period and the wake-up delay and compare it with a low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset).

[0381] For example, the terminal may comprehensively consider the synchronization signal block (e.g., SSB) period and the wake-up delay and compare them with the low-power wake-up signal opportunity-to-paging opportunity / paging frame offset (e.g., LP-PO / PF offset). Specifically, if the synchronization signal block (e.g., SSB) period * number of synchronization signal block (e.g., SSB) receptions required + wake-up delay is smaller than the low-power wake-up signal opportunity-to-paging opportunity / paging frame offset (e.g., LP-PO / PF offset), more specifically, if it is smaller than the time interval between the end of the last low-power wake-up signal monitoring opportunity (e.g., LMO) within the low-power wake-up signal opportunity (e.g., LO) requiring reception and the start of the target paging opportunity (e.g., PO) or paging frame (e.g., PF), the two values ​​may be determined to be compatible. If compatible, the low-power wake-up signal (e.g., LP-WUS) may be determined to be usable.

[0382] Through these methods, the terminal can clearly determine the availability of a low-power wake-up signal (e.g., LP-WUS). If it is determined that the low-power wake-up signal (e.g., LP-WUS) is not in use, the terminal may select another paging opportunity (e.g., PO) or use the conventional method of receiving a paging opportunity (e.g., PO) / paging early indication (e.g., PEI) at every paging cycle.

[0383] According to one embodiment of the present disclosure, [Method #3], an offset selection method considering the period of a synchronization signal block (e.g., SSB) may be provided.

[0384] For example, a base station may indicate multiple low-power wake-up signal opportunity-to-paging opportunity / paging frame offsets (e.g., LP-PO / PF offset) to support terminals with different wake-up delays. Since the actual wake-up delay of the terminal depends on the set synchronization signal block (e.g., SSB) period, the terminal may need to consider the synchronization signal block (e.g., SSB) period to select one of the multiple low-power wake-up signal opportunity-to-paging opportunity / paging frame offsets (e.g., LP-PO / PF offset).

[0385] For example, to determine the offset, a larger offset can be determined by considering "Actual Offset X = Synchronization Signal Block (e.g., SSB) Period * Number of Sync Signal Block (e.g., SSB) Received + Wake-up Delay." In this case, the following can be additionally considered.

[0386] For example, the period of a synchronization signal block (e.g., SSB) can be assumed to be a specific value rather than a set period. For example, the period assumption of the proposed method #1 (or the assumed period) can be used, or 20ms can always be assumed regardless of the set period.

[0387] For example, the number of times a synchronization signal block (e.g., SSB) needs to be received can be determined based on a value reported by the terminal or can be defined in advance.

[0388] For example, the wake-up delay may be the main radio (e.g., MR) activation time reported by the terminal. If the synchronization signal block (e.g., SSB) period and the number of times the synchronization signal block (e.g., SSB) needs to be received are already taken into account in the wake-up delay reported by the terminal, then X = wake-up delay.

[0389] According to one embodiment of the present disclosure, [Method #4], a method for handling a synchronization signal block (e.g., SSB) period may be provided.

[0390] For example, a base station may set the synchronization signal block (e.g., SSB) period of a serving cell to a terminal through upper layer signaling for various purposes. The terminal receives a system information block (e.g., SIB) or a serving cell setting via a radio resource control (e.g., RRC) message and may consider the synchronization signal block (e.g., SSB) period of the corresponding cell. For example, when the synchronization signal block (e.g., SSB) period is considered in the reception of a low-power wake-up signal (e.g., LP-WUS), at least one of the following may be considered.

[0391] For example, the synchronization signal block (e.g., SSB) period can be assumed to be a specific value (e.g., 20ms), and based on this, the reception of the low-power wake-up signal (e.g., LP-WUS) or the wake-up delay can be determined.

[0392] For example, even if an additional synchronization signal block (e.g., SSB) is transmitted through another method such as an on-demand synchronization signal block (e.g., SSB) or the synchronization signal block (e.g., SSB) period is dynamically changed, if the synchronization signal block (e.g., SSB) period is considered for the reception of a low-power wake-up signal (e.g., LP-WUS) or the determination of a wake-up delay, the reception of a low-power wake-up signal (e.g., LP-WUS) or the wake-up delay may be determined based on the synchronization signal block (e.g., SSB) period included in the system information block (e.g., SIB).

[0393] For example, in cases where the synchronization signal block (e.g., SSB) period can be dynamically changed among period candidates through other methods such as an on-demand synchronization signal block (e.g., SSB), when the synchronization signal block (e.g., SSB) period is considered for the reception of a low-power wake-up signal (e.g., LP-WUS) or the determination of a wake-up delay, the reception of a low-power wake-up signal (e.g., LP-WUS) or the wake-up delay may be determined based on the largest synchronization signal block (e.g., SSB) period among the period candidates that the terminal can be instructed to receive.

[0394] For example, in cases where the period of a synchronization signal block (e.g., SSB) among the period candidates can be dynamically changed through other methods such as an on-demand synchronization signal block (e.g., SSB), and the period of the synchronization signal block (e.g., SSB) is considered for receiving a low-power wake-up signal (e.g., LP-WUS) or determining a wake-up delay, the base station may set a reference period candidate among the period candidates, and the terminal may determine the reception of a low-power wake-up signal (e.g., LP-WUS) or the wake-up delay based on the reference period candidate regardless of the dynamically directed synchronization signal block (e.g., SSB) period.

[0395] For example, a terminal in radio resource control connected mode (e.g., RRC-CONNECTED mode) can determine the synchronization signal block (e.g., SSB) period of the primary serving cell configuration as the representative synchronization signal block (e.g., SSB) period.

[0396] For example, a terminal in radio resource control connected mode (e.g., RRC-CONNECTED mode) can determine the actual wake-up delay based on the synchronization signal block (e.g., SSB) period included in the system information block (e.g., SIB) rather than the synchronization signal block (e.g., SSB) period included in the serving cell configuration. This may be done to ensure identical operation with a radio resource control idle (e.g., RRC-IDLE) terminal.

[0397] For example, a terminal in radio resource control connected mode (e.g., RRC-CONNECTED mode) can determine the actual wake-up delay based on the synchronization signal block (e.g., SSB) period included in the serving cell settings. This may be to determine the time length required to receive the synchronization signal block (e.g., SSB) based on the synchronization signal block (e.g., SSB) settings of the current serving cell.

[0398] For example, if a terminal can receive a low-power wake-up signal (e.g., LP-WUS) corresponding to multiple cells, or if a terminal using multiple cells can receive a low-power wake-up signal (e.g., LP-WUS), the terminal can determine the actual wake-up delay based on a representative synchronization signal block (e.g., SSB) period, or assume the synchronization signal block (e.g., SSB) period to a specific value (e.g., 20ms) and determine the actual wake-up delay based thereon.

[0399] For example, to select the period of a representative synchronization signal block (e.g., SSB), the following may be considered.

[0400] For example, the terminal may determine the synchronization signal block (e.g., SSB) period included in the received system information block (e.g., SIB) as the representative synchronization signal block (e.g., SSB) period, rather than the synchronization signal block (e.g., SSB) period included in the serving cell configuration.

[0401] For example, the terminal can determine the period of the synchronization signal block (e.g., SSB) of the serving cell configuration corresponding to the lowest cell ID as the period of the representative synchronization signal block (e.g., SSB).

[0402] For example, the terminal can determine the period of the synchronization signal block (e.g., SSB) of the primary serving cell configuration as the period of the representative synchronization signal block (e.g., SSB).

[0403] For example, the terminal can determine the period of the synchronization signal block (e.g., SSB) of the serving cell configuration in which the low-power wake signal (e.g., LP-WUS) is configured as the period of the representative synchronization signal block (e.g., SSB).

[0404] For example, if there are multiple serving cells with a low-power wake-up signal (e.g., LP-WUS) set, the terminal among them may determine the synchronization signal block (e.g., SSB) period of the serving cell setting corresponding to the lowest cell ID as the representative synchronization signal block (e.g., SSB) period.

[0405] For example, the terminal can determine the period of the synchronization signal block (e.g., SSB) of the serving cell setting corresponding to the lowest cell ID within the intra-band of the serving cell where the low-power wake-up signal (e.g., LP-WUS) is set as the period of the representative synchronization signal block (e.g., SSB).

[0406] According to one embodiment of the present disclosure, [Method #5], a method for handling dynamic synchronization signals such as a synchronization signal block (e.g., SSB) / tracking reference signal (e.g., TRS) may be provided.

[0407] In the present disclosure, an improved method is proposed to utilize a dynamic synchronization signal (e.g., an on-demand synchronization signal block (e.g., SSB) or a tracking reference signal (e.g., TRS)) to maximize the operational efficiency of a terminal's low-power wake-up signal (e.g., LP-WUS). For example, this may aim to overcome the wake-up delay limitations of existing synchronization signal block (e.g., SSB) period-based synchronization acquisition methods and to support faster and more efficient low-power wake-up signal (e.g., LP-WUS) operation through the dynamic synchronization signal.

[0408] For example, unlike conventional methods where the timing of synchronization acquisition by a terminal is determined by the period of a synchronization signal block (e.g., SSB), synchronization can be acquired at an earlier time by utilizing dynamic synchronization signals transmitted by a base station (e.g., on-demand synchronization signal block (e.g., SSB) or tracking reference signals (e.g., TRS)). This can reduce wake-up delay and may affect the availability of low-power wake-up signals (e.g., LP-WUS) and the selection of paging opportunities (e.g., PO). In this disclosure, the following mechanism is proposed regarding the operation of low-power wake-up signals (e.g., LP-WUS) during the transmission of dynamic synchronization signals.

[0409] When the terminal receives a tracking reference signal (e.g., TRS) setting or an on-demand synchronization signal block (e.g., SSB) setting through a system information block (e.g., SIB 17), the low-power wake-up signal (e.g., LP-WUS) may be monitored even if it is determined that the low-power wake-up signal (e.g., LP-WUS) is not available due to a wake-up delay caused by the existing synchronization signal block (e.g., SSB) period-based synchronization acquisition. Depending on the availability of the dynamic synchronization signal, the following operations may be performed.

[0410] I. When Dynamic Synchronization Signal is Available

[0411] Criteria for Determining Dynamic Synchronization Signal Availability: The terminal may determine dynamic synchronization signal availability based on one or more of the following options. The terminal may select an appropriate option considering network configuration and terminal implementation complexity.

[0412] Option 1: (Configuration-based) If the terminal receives a setting related to a tracking reference signal (e.g., TRS) or an on-demand synchronization signal block (e.g., SSB) via a system information block (e.g., SIB 17) or dedicated radio resource control (e.g., RRC) signaling, the terminal may determine that a dynamic synchronization signal is available. For example, this option may be simple and configuration-dependent.

[0413] Option 2: (Signal detection) If the terminal actually successfully detects a dynamic synchronization signal (e.g., when the synchronization signal block correlation operation is successful, or when the received signal code power (e.g., RSCP) / reference signal received power (e.g., RSRP) of a certain quality or higher is measured), the terminal may determine that the dynamic synchronization signal is available.

[0414] Option 3: (Explicit instruction) If the terminal receives an instruction regarding the availability of a dynamic synchronization signal and setting information of a dynamic synchronization signal being transmitted via a low-power wake-up signal (e.g., LP-WUS) message, the terminal may determine that the dynamic synchronization signal is available.

[0415] Option 4: (Combination 1 - Settings + Signal) Based on settings-based availability, but additionally, if signal detection-based availability conditions are satisfied, the terminal can determine that the dynamic synchronization signal is finally available.

[0416] Option 5: (Combination 2 - Config + Explicit) Based on configuration-based availability, but additionally, the terminal can determine that the dynamic synchronization signal is finally available only if the explicit indication-based availability condition is satisfied.

[0417] For example, only terminals capable of fast synchronization acquisition through dynamic synchronization signals can receive a wake-up instruction from the corresponding low-power wake-up signal opportunity (e.g., LO).

[0418] For example, the availability of a low-power wake signal (e.g., LP-WUS) through a dynamic synchronization signal can be determined based on the following factors.

[0419] 1. Delta_T_dynamic_sync_to_PO: Time interval from the time the dynamic synchronization signal is received to the paging opportunity (e.g., PO).

[0420] 2. T_dynamic_sync: Dynamic synchronization signal transmission period / interval

[0421] 3. N_dynamic_sync_required: The number of dynamic synchronization signal receptions required to achieve target performance. Processing time and retry time for each reception attempt may be considered.

[0422] 4. UE_wakeup_delay: Terminal-specific wake-up time (main radio (e.g., MR) activation time, etc.).

[0423] The terminal calculates the wake delay and low-power wake signal (e.g., LP-WUS) availability through the following formula or a similar mechanism.

[0424] 1. Total weather delay:

[0425] UE_wakeup_delay + T_dynamic_sync * N_dynamic_sync_required

[0426] 2. Conditions for determining low-power wake-up signal (e.g., LP-WUS) availability:

[0427] Delta_T_dynamic_sync_to_PO > UE_wakeup_delay + T_dynamic_sync* N_dynamic_sync_required

[0428] In this case, the availability of the low-power wake-up signal (e.g., LP-WUS) may be temporarily applied only during the corresponding dynamic synchronization signal transmission period. The terminal can determine the availability of the low-power wake-up signal (e.g., LP-WUS) by utilizing the calculated wake-up delay and reflect it in the selection of a paging opportunity (e.g., PO) (e.g., selection of the next paging opportunity (e.g., PO)).

[0429] II. When the dynamic synchronization signal is not available

[0430] For example, the determination of low-power wake-up signal (e.g., LP-WUS) availability based on the synchronization acquisition time based on the existing synchronization signal block (e.g., SSB) period can be maintained. For example, if it is determined that the dynamic synchronization signal is not available, the terminal can calculate the wake-up delay based on the synchronization signal block (e.g., SSB) period and determine the availability of the low-power wake-up signal (e.g., LP-WUS) according to the existing method.

[0431] For example, a base station may set separate radio resource control (e.g., RRC) parameters to control the reception operation of a low-power wake signal (e.g., LP-WUS) based on a dynamic synchronization signal. For example, the separate radio resource control (e.g., RRC) parameters may be parameters that set at least one of the following.

[0432] 1. Configured to perform low-power wake-up signal (e.g., LP-WUS) operation based on the existing synchronization signal block (e.g., SSB) period (legacy method), regardless of the availability of dynamic synchronization signals.

[0433] 2. Configure to perform low-power wake signal (e.g., LP-WUS) monitoring only when the dynamic synchronization signal is available.

[0434] 3. Configure the system to monitor low-power wake-up signals (e.g., LP-WUS) for both available and unavailable dynamic synchronization signals, but apply different wake-up delay adjustment methods and low-power wake-up signal (e.g., LP-WUS) availability determinations.

[0435] For example, a low-power wake-up signal (e.g., LP-WUS) message may include an explicit dynamic synchronization signal availability indicator in a manner similar to a paging early indication (e.g., PEI). This allows the terminal to immediately check the availability of the dynamic synchronization signal upon receiving the low-power wake-up signal (e.g., LP-WUS) and immediately perform wake-up delay adjustment. This enables the terminal to respond quickly to real-time network changes and can improve power efficiency by reducing unnecessary wake-up attempts.

[0436] For example, when considering a dynamic synchronization signal, a terminal that is not available with a low-power wake signal (e.g., LP-WUS) due to a wake delay may also be allowed to monitor the low-power wake signal (e.g., LP-WUS) only in the following cases.

[0437] 1. When a dynamic synchronization signal-related setting is received via System Information Block (e.g., SIB 17) or L1 / Radio Resource Control (e.g., RRC) signaling

[0438] 2. When the above dynamic synchronization signal is available (e.g., when the above-defined availability determination criteria are satisfied)

[0439] For example, additionally, when the availability of a tracking reference signal (e.g., TRS) is indicated via a system information block (e.g., SIB) for configuring a low-power wake-up signal (e.g., LP-WUS), a method may be considered in which information regarding the valid interval for such availability is also indicated. This allows the terminal to clearly recognize the interval where the tracking reference signal (e.g., TRS) availability is valid and to efficiently utilize dynamic synchronization signals within that interval. For example, the following fields may be added within the system information block (e.g., SIB 17) message:

[0440] For example, Tracking Reference Signal (e.g., TRS) Availability Valid Period (period): A field indicating the time period during which the Tracking Reference Signal (e.g., TRS) availability indication is valid. This field may include the start and end times during which the Tracking Reference Signal (e.g., TRS) availability is valid. This information may specify the actual time as the period and offset.

[0441] For example, start time: The start time at which tracking reference signal (e.g., TRS) availability is valid can be based on a specific system frame number (e.g., SFN0).

[0442] For example, length / end time: The length of time or end time during which tracking reference signal (e.g., TRS) availability is valid.

[0443] For example, periodicity: the period during which tracking reference signal (e.g., TRS) availability repeats.

[0444] For example, offset: the offset at which tracking reference signal (e.g., TRS) availability begins within a period.

[0445] Additionally, for example, among the configured tracking reference signal (e.g., TRS) settings, a specific tracking reference signal (e.g., TRS) setting may be configured to be usable for receiving a low-power wake-up signal (e.g., LP-WUS). This allows the terminal to clearly recognize whether a specific tracking reference signal (e.g., TRS) setting can be used for receiving a low-power wake-up signal (e.g., LP-WUS). In this case, the terminal can adjust the availability and wake-up delay of the low-power wake-up signal (e.g., LP-WUS) based on the availability of the tracking reference signal (e.g., TRS) among the configured tracking reference signal (e.g., TRS) settings that can be used for receiving the low-power wake-up signal (e.g., LP-WUS). For example, the following field may be added within a system information block (e.g., SIB 17) message:

[0446] For example, a tracking reference signal (e.g., TRS) applicable to a low-power wake signal (e.g., LP-WUS): a field indicating a tracking reference signal (e.g., TRS) setting applicable to receiving a low-power wake signal (e.g., LP-WUS). This field may include whether a specific tracking reference signal (e.g., TRS) setting applicable to receiving a low-power wake signal (e.g., LP-WUS).

[0447] For example, Tracking Reference Signal (e.g., TRS) Configuration ID: Identifier of a specific Tracking Reference Signal (e.g., TRS) configuration

[0448] For example, Low Power Wake Signal (e.g., LP-WUS) Usage: Whether the corresponding Tracking Reference Signal (e.g., TRS) setting can be used for receiving the Low Power Wake Signal (e.g., LP-WUS) (e.g., Enabled / Unavailable)

[0449] Alternatively, for example, by indicating only the ID, it may be indicated / set that the corresponding tracking reference signal (e.g., TRS) setting can be used for a low-power wake signal (e.g., LP-WUS).

[0450] Through this information, the terminal can clearly recognize the intervals where tracking reference signal (e.g., TRS) availability is valid and efficiently utilize dynamic synchronization signals within those intervals. This reduces unnecessary attempts to wake up and further improves power efficiency.

[0451] According to one embodiment of the present disclosure [Method #6], an additional element (term) for terminal waking delay may be provided.

[0452] This disclosure presents a method to improve accuracy by considering various factors that influence the calculation of weather delay. Weather delay can vary depending on various factors, such as the type of weather receiver (e.g., WUR; wake-up receiver), the complexity of the target low-power weather signal monitoring opportunity (e.g., LMO), and the value of M. For example, additional factors considering the following may be taken into account in the calculation of weather delay.

[0453] 1. Weather receiver (e.g., WUR) type

[0454] For example, the wake-up delay may vary depending on the type of wake-up receiver (e.g., WUR). For instance, an on-off keying (e.g., OOK)-based wake-up receiver (e.g., WUR) may have a low wake-up delay, whereas an Orthogonal Frequency Division Multiplexing (e.g., OFDM)-based wake-up receiver (e.g., WUR) may have a high wake-up delay. For instance, the wake-up delay value may be adjusted considering the type of wake-up receiver (e.g., WUR). For instance, it may be +0ms for an on-off keying (e.g., OOK)-based wake-up receiver (e.g., WUR) and +5ms for an OFDM-based wake-up receiver (e.g., WUR).

[0455] 2. Complexity of low-power weather signal monitoring opportunities (e.g., LMO)

[0456] For example, the wake-up delay may vary depending on the complexity of the target low-power wake-up signal (e.g., LP-WUS) monitoring object. Complex monitoring objects require more processing time, which can increase the wake-up delay. More specifically, if one monitoring object is configured per beam / synchronization signal block (e.g., SSB), 0 ms is added, and if two or more monitoring objects are configured, especially if the monitoring objects are configured with different information, several ms may be added. For example, for complex monitoring objects, it may be +3 ms.

[0457] 3. M value

[0458] For example, even with the same weather receiver (e.g., WUR) type, the weather delay may vary depending on the number of configured on-off keying (e.g., OOK) symbols within the symbol. For instance, it may be +0ms when M=1, +2ms when M=2, and +4ms when M=3.

[0459] For example, by comprehensively considering the above factors, the weather delay can be calculated as follows.

[0460] Weather Delay = Base Weather Delay + Weather Receiver (e.g., WUR) Type Factor + Monitoring Object Complexity Factor + M Value Factor

[0461] For example, according to the present proposal, the accuracy of weather delay estimation can be improved by considering various factors in the estimation of weather delay.

[0462] In the present disclosure, the following is proposed.

[0463] 1. A method for a terminal to determine a synchronization signal block (e.g., SSB) period by receiving a system information block (e.g., SIB 17) from a base station and to calculate a wake-up delay based on the synchronization signal block (e.g., SSB) period. Here, for example, the system information block (e.g., SIB 17) may include information about the synchronization signal block (e.g., SSB) period and information about a low-power wake-up signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset).

[0464] For example, a method for calculating a wake-up delay by assuming that a 20ms period is applied when the terminal has a synchronization signal block (e.g., SSB) period of 10ms.

[0465] For example, a method for determining the availability of a low-power wake signal (e.g., LP-WUS) by comparing a terminal with a set low-power wake signal opportunity-to-paging opportunity offset (e.g., LP-to-PO offset) and a calculated wake delay.

[0466] For example, a method in which a terminal selects another paging opportunity (e.g., PO) when a low-power wake-up signal (e.g., LP-WUS) is unavailable, or receives a paging opportunity (e.g., PO) / paging early indication (e.g., PEI) during each existing paging cycle.

[0467] 2. A method in which a base station uses upper layer signaling to set various synchronization signal block (e.g., SSB) cycles for a terminal.

[0468] For example, in various embodiments of the present disclosure, a system information block (e.g., SIB) may include information related to radio paging of a terminal (e.g., UE-RadioPagingInfo). For example, the information related to radio paging (e.g., UE-RadioPagingInfo) may include information related to a band where a low-power wake-up signal (e.g., LP-WUS) is supported (e.g., LPWUS-SupportedBandInfo).

[0469] Here, for example, information related to a band where a low-power wake signal (e.g., LP-WUS) is supported (e.g., LPWUS-SupportedBandInfo) may include information related to a minimum time gap (e.g., minimumTimeGap) related to the capabilities of the terminal.

[0470] For example, the information related to the minimum time gap (e.g., minimumTimeGap) may include at least one of the following: a value of 0, 1, and 2 as an item for a wake-up delay for a synchronization signal block (e.g., SSB) period of less than 20ms (or 20ms or less); a value of 0, 1, and 2 as an item for a wake-up delay for a synchronization signal block (e.g., SSB) period of 40ms; a value of 0, 1, and 2 as an item for a wake-up delay for a synchronization signal block (e.g., SSB) period of 80ms; and a value of 0, 1, and 2 as an item for a wake-up delay for a synchronization signal block (e.g., SSB) period of 160ms.

[0471] Alternatively, for example, the information related to the minimum time gap (e.g., minimumTimeGap) may include one of the values ​​0, 1, and 2 as an entry for the wake-up delay for each allowed synchronization signal block (e.g., SSB) period.

[0472] For example, a value expressed as one of 0, 1, and 2 above may have the meaning of an index within the information containing the value, and may actually be used as a predefined value mapped to the index for each applied form.

[0473] For example, the time position of a low-power wake signal opportunity (e.g., LO) for a terminal's paging opportunity (e.g., PO) can be determined by a reference paging opportunity (e.g., PO) / paging frame (e.g., PF) and a set frame level offset.

[0474] For example, the reference point (reference paging opportunity (eg, PO) / paging frame (eg, PF)) may be the start of the paging frame (eg, PF) associated with the low-power wake-up signal opportunity (eg, LO), or (if mapping paging opportunities (eg, PO) from multiple paging frames (eg, PF) to one low-power wake-up signal opportunity (eg, LO) is configured) the start of the first paging frame (eg, PF)(s) associated with the low-power wake-up signal opportunity (eg, LO).

[0475] For example, the reference paging frame (e.g., PF) for a low-power wake signal opportunity (e.g., LO) of a paging opportunity (e.g., PO) is (system frame number (e.g., SFN) for the paging frame (e.g., PF)) - floor(i PO / N S ) * Can be provided by T / N.

[0476] For example, the frame-level offset between a low-power wake signal opportunity (e.g., LO) and a reference paging opportunity (e.g., PO) / paging frame (e.g., PF) can be provided by lpwus-LO-FrameOffsetList of the system information block (e.g., SIB1). lpwus-PO-NumPerLO is N s If smaller, the terminal is of offsetForLongerWakeUpDelay (if set) provided in lpwus-LO-FrameOffsetList (floor(i s / lpwus-PO-NumPerLO)+1)th value or offsetForShorterWakeUpDelay(if set) of (floor(i s You can use the / lpwus-PO-NumPerLO)+1)th value.

[0477] For example, if only one of offsetForLongerWakeUpDelay and offsetForShorterWakeUpDelay is set in lpwus-LO-FrameOffsetList, and the interval between the end of the last low-power wake-up signal monitoring opportunity (e.g., LMO) that the terminal will monitor in the low-power wake-up signal opportunity (e.g., LO) corresponding to offsetForLongerWakeUpDelay or offsetForShorterWakeUpDelay (the one set) and the start of the corresponding paging opportunity (e.g., PO) is no less than the wake-up delay supported by the terminal, the terminal can monitor the low-power wake-up signal opportunity (e.g., LO) associated with that offset.

[0478] Otherwise, the terminal may follow the paging monitoring procedure.

[0479] For example, if both offsetForLongerWakeUpDelay and offsetForShorterWakeUpDelay are set in lpwus-LO-FrameOffsetList, the terminal can monitor the low-power wake-up signal opportunity (e.g., LO) associated with the offsetForShorterWakeUpDelay value if the interval between the end of the last low-power wake-up signal monitoring opportunity (e.g., LMO) that the terminal will monitor and the start of the corresponding paging opportunity (e.g., PO) is no less than the wake-up delay reported by the terminal.

[0480] Otherwise, if the interval between the end of the last low-power wake-up signal monitoring opportunity (e.g., LMO) that the terminal will monitor in the low-power wake-up signal opportunity (e.g., LO) associated with the offsetForLongerWakeUpDelay value and the start of the corresponding paging opportunity (e.g., PO) is no less than the wake-up delay reported by the terminal, the terminal can monitor the low-power wake-up signal opportunity (e.g., LO) associated with the offsetForLongerWakeUpDelay value.

[0481] Otherwise, the terminal may follow the paging monitoring procedure.

[0482] The present disclosure describes a method for effectively waking up terminals with different wake times via a low-power wake signal (e.g., LP-WUS) and triggering paging reception. To this end, a method is proposed for allocating a low-power wake signal opportunity (e.g., LO) separated according to the wake delay time to a terminal, determining a terminal identifier or terminal group identifier to be used within the low-power wake signal opportunity (e.g., LO), and determining a paging opportunity (e.g., PO) to be used for receiving a paging message triggered after receiving the low-power wake signal opportunity (e.g., LO).

[0483] For example, when using a low-power wake-up signal (e.g., LP-WUS) to wake up an idle terminal and trigger paging reception, additional delay may occur from the time traffic is generated until the terminal is woken up by the base station signal compared to conventional paging methods. This degrades the responsiveness of the terminal and can cause problems with the delivery of urgent messages. To reduce these disadvantages, it may be important to allocate a paging opportunity at the earliest possible time the terminal can receive it after receiving the low-power wake-up signal (e.g., LP-WUS).

[0484] In the proposed method, a base station first generates one or more low-power wake-up signal opportunities (e.g., LO) considering the wake-up delay time of a terminal, and can assign each low-power wake-up signal opportunity (e.g., LO) to a group of terminals having the corresponding delay time. Through this, terminals with similar delay times can be managed as a single group. Subsequently, a terminal identifier or terminal group identifier to be used within each low-power wake-up signal opportunity (e.g., LO) is determined, and the paging opportunity (e.g., PO) located at the earliest time after receiving the low-power wake-up signal opportunity (e.g., LO) can be mapped to the corresponding low-power wake-up signal opportunity (e.g., LO).

[0485] For example, a terminal monitors a low-power wake-up signal opportunity (e.g., LO) assigned to it, and when the low-power wake-up signal opportunity (e.g., LO) arrives, it wakes up and checks the assigned identifier. If the identifier matches itself, the terminal can attempt to receive a paging message from the paging opportunity (e.g., PO) mapped to the low-power wake-up signal opportunity (e.g., LO). Through this process, terminals with different wake-up delay times can be effectively controlled, and unnecessary wake-up operations can be reduced, thereby minimizing power consumption. Furthermore, through optimized mapping between the low-power wake-up signal opportunity (e.g., LO) and the paging opportunity (e.g., PO), the delay time from receiving the low-power wake-up signal (e.g., LP-WUS) to receiving the paging message can be minimized.

[0486] The present disclosure relates to a method for allocating a low-power wake-up signal opportunity (e.g., LO) and a terminal subgroup to terminals with different wake-up times, and a method for a terminal to receive an identifier of the terminal or an identifier of a group including the terminal in the said low-power wake-up signal opportunity (e.g., LO).

[0487] In the present disclosure, a low-power weather signal opportunity (e.g., LO) may be a concept comprising one or more low-power weather signal monitoring opportunities (e.g., LMO; LP-WUS monitoring occasion). In other words, one low-power weather signal monitoring opportunity (e.g., LMO) may be replaced by one low-power weather signal opportunity (e.g., LO), or a group of low-power weather signal monitoring opportunities (e.g., LMO) consisting of one or more low-power weather signal monitoring opportunities (e.g., LMO) may be replaced by a low-power weather signal opportunity (e.g., LO).

[0488] This can be useful for improving reception performance by associating each low-power weather signal monitoring opportunity (e.g., LMO) within a low-power weather signal opportunity (e.g., LO) with a beam or reference signal provided by a base station or predefined, and by always conveying the same information from the low-power weather signal monitoring opportunities (e.g., LMO) within the low-power weather signal opportunity (e.g., LO), allowing the terminal to select and receive the best low-power weather signal monitoring opportunity (e.g., LMO) from the reference signal, or by combining the signals received from each low-power weather signal monitoring opportunity (e.g., LMO).

[0489] For example, the number of low-power weather signal monitoring opportunities (e.g., LMO) within a low-power weather signal opportunity (e.g., LO) can be directly set through a message such as a system information block (e.g., SIB 17) from the base station, or can be derived from the number of transmissions per cycle, such as a reference signal that can be associated with each low-power weather signal monitoring opportunity (e.g., LMO).

[0490] Alternatively, for example, without an explicit association, the terminal may assume that each low-power weather signal monitoring opportunity (e.g., LMO) is a separate transmission. In a series of operations, the terminal may assume that the same information is provided in the low-power weather signal monitoring opportunity (e.g., LMO) within the low-power weather signal opportunity (e.g., LO). Additionally, the following may be considered in the low-power weather signal opportunity (e.g., LO).

[0491] For example, in a given low-power wake signal opportunity (e.g., LO), the terminal may perform monitoring in all monitoring opportunities (e.g., MO) within the low-power wake signal opportunity (e.g., LO), or may perform monitoring only in specific monitoring opportunities (e.g., MO).

[0492] For example, the number of low-power weather signal monitoring opportunities (e.g., LMO) within a low-power weather signal opportunity (e.g., LO) may differ from the number of associated beams or reference signals. This may be due to consideration of the capacity of the low-power weather signal monitoring opportunities (e.g., LMO). In such cases, the terminal may consider the following.

[0493] For example, if the number of low-power weather signal monitoring opportunities (e.g., LMO) X within a low-power weather signal opportunity (e.g., LO) is greater than the number of associated beams or reference signals Y, it can be assumed that the nth low-power weather signal monitoring opportunity (e.g., LMO) is associated with the "(n-1) mod Y + 1"th beam or transmitted reference signal.

[0494] For example, if the number X of low-power weather signal monitoring opportunities (e.g., LMO) within a low-power weather signal opportunity (e.g., LO) is less than the number Y of associated beams or reference signals, the first low-power weather signal monitoring opportunity (e.g., LMO) may be associated with the "system frame number (e.g., SFN) mod Y" of which the low-power weather signal monitoring opportunity (e.g., LMO) is included. Additionally, the nth low-power weather signal monitoring opportunity (e.g., LMO) may be associated with the "(m+n-1) mod Y + 1" of which the m-th beam or reference signal is included in the first low-power weather signal monitoring opportunity (e.g., LMO).

[0495] According to one embodiment of the present disclosure [Method #7], a separated low-power weather signal opportunity (e.g., LO) for different weather delays may be provided.

[0496] In this method, multiple separate low-power wake-up signal opportunities (e.g., LO) corresponding to a single paging opportunity (e.g., PO) are allocated for terminals having different wake-up delay times. To this end, the location of the low-power wake-up signal opportunity (e.g., LO) is determined to be earlier by a certain time offset from each paging opportunity (e.g., PO) determined to be monitored by the terminal, and by applying different offsets when different wake-up delay times are present, separate low-power wake-up signal opportunities (e.g., LO) for each offset can be allocated to a single paging opportunity (e.g., PO).

[0497] Since the location of the paging opportunity (e.g., PO) to be monitored by the terminal is determined by the location of the first base station-to-terminal physical control channel (e.g., PDCCH) monitoring opportunity (e.g., MO) of each paging opportunity (e.g., PO) set within the paging frame (e.g., PF) to be monitored by the terminal, the following method may be considered to determine the location of the low-power wake signal opportunity (e.g., LO) through this.

[0498] Method 1. Frame offset T from the slot where the paging opportunity (e.g., PO) is located. Frame and / or slot offset T slot It can be assumed that a low-power wake signal opportunity (e.g., LO) starts in the previous slot.

[0499] Method 2. Frame offset T from the symbol where the paging opportunity (e.g., PO) is located. Frame and / or symbol offset T symbol It can be assumed that a low-power weather signal opportunity (e.g., LO) begins at a point that is separated by that amount.

[0500] Method 3. If a paging early indication (e.g., PEI) is set, frame offset T from the slot where the paging early indication opportunity (e.g., PEI-O) monitoring the paging early indication (e.g., PEI) is located. Frame and / or slot offset T slot It can be assumed that a low-power wake signal opportunity (e.g., LO) starts in the previous slot.

[0501] Method 4. If a paging early indication (e.g., PEI) is set, frame offset T from the symbol where the paging early indication opportunity (e.g., PEI-O) monitoring the paging early indication (e.g., PEI) is located. Frame and / or symbol offset T symbol It can be assumed that a low-power weather signal opportunity (e.g., LO) begins at a point that is separated by that amount.

[0502] Method 5. If a paging early indication (e.g., PEI) is set, frame offset T from the first paging frame (e.g., PF) (e.g., the reference point of the paging early indication (e.g., PEI)) among the paging frames (e.g., PF) corresponding to a single paging early indication (e.g., PEI). Frame and / or slot offset T slot It can be assumed that a low-power wake signal opportunity (e.g., LO) starts in the previous slot.

[0503] At this time, at least one of the following methods may be considered to determine the frame offset, slot offset, and / or symbol offset according to the weather delay time.

[0504] Method 1. Slot Offset T slot and / or symbol offset T symbol It uses the same offset for each wake delay time (if any), and frame offset T Frame It can be given according to the weather delay time.

[0505] For example, by allocating only the frame offset according to the wake-up delay time, it may be possible for different terminal groups having different wake-up delay times and using the same paging opportunity (e.g., PO) at the same location within the same or different paging frames (e.g., PF) to simultaneously share a single low-power wake-up signal opportunity (e.g., LO).

[0506] For example, in particular, if the difference in frame offsets that varies with different wake delay times is equal to an integer multiple of the length of the idle discontinuous reception (e.g., DRX) cycle, a group of terminals receiving the same paging opportunity (e.g., PO) in different paging frames (e.g., PF) can share one low-power wake signal opportunity (e.g., LO).

[0507] Method 2. Frame Offset T Frame , slot offset T slot and / or symbol offset T symbol This can be given according to the weather delay time.

[0508] For example, to determine the above frame offset, slot offset, and / or symbol offset for each weather delay time,

[0509] i) Values ​​defined in the terminal's capabilities may be used.

[0510] ii) Values ​​indicated / set through system information blocks (e.g., SIB) or other higher-level signaling (AMF through NAS signaling, etc.) may be used.

[0511] iii) A predefined length may be used.

[0512] For example, if multiple methods are used to determine a single offset, the offset may be determined as the sum of one or more elements. For example, the offset T is determined as T=a+b+c+d, where a is a value defined as a capability, b is a value indicated through a system information block (e.g., SIB), c is a preset time length, and d is 0 if no paging early indication (e.g., PEI) is set, a preset value if paging early indication (e.g., PEI) is set, or a value obtained through the pei-FrameOffset or firstPDCCH-MonitoringOccasionOfPEI-O parameter included in the paging early indication (e.g., PEI) reception setting.

[0513] According to one embodiment of the present disclosure [Method #7-1], a shared low-power weather signal opportunity (e.g., LO) for different weather delays may be provided.

[0514] In this method, a method is proposed for sharing a single low-power wake-up signal opportunity (e.g., LO) for terminals having different wake-up delay times. Through this, the terminal can monitor an appropriate low-power wake-up signal opportunity (e.g., LO) according to the wake-up delay time. The specific method may be as follows.

[0515] First, different offsets are assigned for each wake-up delay time, and the first offset is used when allocating a low-power wake-up signal opportunity (e.g., LO), and the low-power wake-up signal opportunity (e.g., LO) and / or paging opportunity (e.g., PO) to be received can be determined through the given offset. For example, if the supported wake-up delay types are 100ms, 200ms, 400ms, and 800ms, any corresponding offset such as 150ms, 500ms, 500ms, and 1000ms can be assigned for each offset.

[0516] In this case, for example, an offset to be used by a terminal with a specific capability may be specified without a direct comparison between the wake-up delay and the offset value. For example, the provisions proposed in Method #7 above may be applied to determining low-power wake-up signal opportunities (e.g., LO) and / or paging opportunities (e.g., PO) based on the offset and to assigning offsets based on wake-up delay times.

[0517] For example, if the base station has not separately configured an available wake-up delay, the terminal may operate according to the wake-up delay it supports and the associated offset. For example, the terminal may receive multiple low-power wake-up signal opportunities (e.g., LO) from a determined paging opportunity (e.g., PO) according to the supported wake-up delay, or, if the low-power wake-up signal opportunity (e.g., LO) is configured independently, it may attempt to receive multiple paging opportunities (e.g., PO) from the received low-power wake-up signal opportunity (e.g., LO) based on the wake-up delay. Through this, the terminal can monitor paging opportunities (e.g., PO) by applying an offset that matches its wake-up delay time.

[0518] As a specific example, assuming that terminal A supports a wake-up delay of 100ms and terminal B supports a wake-up delay of 200ms, terminal A may use an offset of 150ms and terminal B may use an offset of 500ms. In this case, terminal A and terminal B share the same low-power wake-up signal opportunity (e.g., LO), but can monitor paging opportunities (e.g., PO) by applying an offset that matches their respective wake-up delays.

[0519] If the base station sets available wake-up delays in the current low-power wake-up signal (e.g., LP-WUS) configuration through upper layer signaling (e.g., SIB), the terminal can operate according to said settings. Specifically, the terminal can select the shortest wake-up delay it can support among the available wake-up delays set by the base station. Then, for example, the terminal can monitor low-power wake-up signal opportunities (e.g., LO) and paging opportunities (e.g., PO) by applying an offset corresponding to the selected wake-up delay. If there are no available wake-up delays set by the base station that the terminal can support, the terminal can stop receiving low-power wake-up signals (e.g., LP-WUS) and perform monitoring of paging opportunities (e.g., PO) based on conventional discontinuous reception (e.g., DRX).

[0520] For example, assuming the base station has configured 200ms and 400ms wake-up delays to be available, terminal A, which supports a 100ms wake-up delay, can perform monitoring of paging opportunities (e.g., PO) based on conventional discontinuous reception (e.g., DRX). For example, terminal B, which supports both 200ms and 400ms wake-up delays, can select the 200ms wake-up delay and apply a 500ms offset. For example, terminal C, which supports only an 800ms wake-up delay, can perform monitoring of paging opportunities (e.g., PO) based on conventional discontinuous reception (e.g., DRX).

[0521] As another example, even if the available wake-up delay explicitly set by the base station is not supported, if the shortest wake-up delay supported by the terminal is smaller than any available wake-up delay set by the base station, the available wake-up delay set by the base station may be determined to be supported. For example, assuming the base station has set 200ms and 400ms wake-up delays as available, terminal A, which supports a 100ms wake-up delay, may also select the 200ms wake-up delay and apply the corresponding offset (e.g., 500ms).

[0522] Through this method, terminals with various weather delay capabilities can efficiently share low-power weather signal opportunities (e.g., LO) while performing optimal operations suited to their respective capabilities.

[0523] Additionally, the base station can dynamically change the available weather delay settings depending on network conditions or changes in traffic patterns. In this case, the changed settings may be notified to terminals through a system information change procedure, and the terminals can readjust the weather delay and offset according to the new settings.

[0524] Through this method, terminals with different wake-up delay times can efficiently monitor low-power wake-up signal opportunities (e.g., LO), and enable the efficient use of network resources.

[0525] According to one embodiment of the present disclosure [Method #8], terminal subgroups classified for different weather delays may be provided.

[0526] For example, different ranges of terminal subgroup indices may be used for terminals with different wake-up delays. This enables resource allocation and terminal group management optimized for each wake-up delay, and allows only terminal k with a specific wake-up delay to be woken up without false alarms, even when terminals with different wake-up delays share a single low-power wake-up signal opportunity (e.g., LO).

[0527] For example, a terminal may support one of two different weather delay capabilities (e.g., short or long). For example, a terminal may be classified into two or more categories based on the supported weather delay. For example, terminals may be distinguished into those supporting short weather delay capabilities and those supporting long weather delay capabilities. In this case, when a total of N terminal subgroups are configured, the first N / 2 (0, 1, ..., ceil(N / 2)-1) (e.g., the subgroup with indices 0, 1, ..., ceil(N / 2)-1) may be assigned to terminals with short wake-up delays, and the second N / 2 (ceil(N / 2), ceil(N / 2)+1, ..., N) (e.g., the subgroup with indices N / 2 (ceil(N / 2), ceil(N / 2)+1, ..., N)) may be assigned to terminals with long wake-up delays. Through this, each terminal can be assigned a subgroup index that matches its wake-up delay characteristics. For example, the ceil(x) function may be a function that outputs the smallest integer not smaller than x.

[0528] To this end, each terminal can determine its terminal subgroup index from the entire terminal group by first applying the number of terminal subgroups, ceil(N / 2), to find its terminal subgroup index when a total of N terminal subgroups are set, and can apply different subgroup index offsets depending on its wake-up delay. For example, a terminal with a short wake-up delay may apply 0 as the subgroup index offset, and a terminal with a long wake-up delay may apply ceil(N / 2) as the subgroup index offset. Through this, the terminal can determine its terminal subgroup index within the range of terminal subgroup indices assigned to it.

[0529] As another example, two or more terminal subgroup index ranges may be used to support two or more different waking delays. For example, if three types of waking delays (short, medium, long) are supported, the entire terminal subgroup index range may be divided into three sections so that a section corresponding to each waking delay is allocated.

[0530] The number of terminal subgroups can be set for each weather delay. In this case, the total number of terminal subgroups can be set separately. The subgroup index offset for each weather delay can be determined as the sum of the number of terminal subgroups having a weather delay smaller than its own weather delay.

[0531] As another example, the terminal subgroup index range corresponding to each waking delay can be set as a partial proportion of the total. For example, 50%, 30%, and 20% of the total terminal subgroup index range can be allocated for short, medium, and long waking delays, respectively. Through this, resources can be flexibly allocated according to the proportion of terminals with each waking delay.

[0532] As another example, a separate terminal subgroup index may be assigned to terminals that support only weather delays greater than a specific weather delay. Terminal subgroups configured based on weather delays in this way can operate similarly to the core network (CN) assigned subgroups of conventional paging subgroups.

[0533] For example, it can be assumed that among a total of N terminal subgroups, terminals that support only high weather delays are assigned to terminal subgroup indices [0, 1, 2, ..., k-1], and Nk terminal subgroups are used for subgrouping other terminals. In this case, it can be assumed that terminals assigned to separate terminal subgroup indices [0, 1, 2, ..., k-1] do not belong to any other Nk terminal subgroups.

[0534] For this operation, the base station may set a weather delay threshold to be assigned a separate terminal subgroup index and k, the number of terminal subgroup indices to be used by terminals exceeding the said weather delay threshold. A terminal that supports a weather delay greater than the weather delay threshold is assumed to be included in one of the subgroup indices [0, 1, 2, ..., k-1], and can derive one subgroup index among k that it is included in based on the terminal ID.

[0535] Alternatively, for example, when a terminal reports multiple weather delays, the separate terminal subgroup index may be assigned to a terminal whose minimum value among the reported delay values ​​is greater than or equal to a specific weather delay.

[0536] Alternatively, for example, when a terminal reports multiple weather delays, the separate terminal subgroup index may be assigned to a terminal that includes a value greater than or equal to a specific weather delay among the reported delay values.

[0537] According to one embodiment of the present disclosure [Method #8-1], non-uniform terminal subgroup sizes for different weather delays may be provided.

[0538] For example, the present disclosure proposes a method for allocating terminal subgroups of different sizes to terminals having different weather delay capabilities. Through the proposed method, it may be possible to allocate optimized terminal subgroups tailored to the characteristics of each weather delay capability.

[0539] For example, assuming that a terminal can have two short or long wake-up delay capabilities (hereinafter Capa1 and Capa2), a different number of subgroups can be assigned to each capability. Specifically, it may be possible to assign 6 subgroups to terminals with Capa1 and 2 subgroups to terminals with Capa2. In this case, the subgroup assignment method can be defined as follows.

[0540] For example, for a terminal with Capa1, subgroup index = floor(terminal identifier / (N*Ns)) mod 6, and the subgroup index range can be [0, 1, 2, 3, 4, 5].

[0541] For example, for a terminal with Capa2, group ID offset = number of subgroups of Capa1 (e.g., 6), subgroup index = (floor(terminal identifier / (N*Ns)) mod 2) + group ID offset, and the subgroup index range can be [6, 7].

[0542] Here, for example, N is the total number of paging frames within a discontinuous reception (e.g., DRX) cycle, Ns is the number of paging times per paging frame, and the terminal identifier may be a value calculated using the terminal's unique identifier (e.g., 5G-S-TMSI).

[0543] The above subgroup allocation method can be implemented in the following two ways.

[0544] Method 1. Assigning two subgroup indices to the terminal, and having the terminal select one based on its wake-up delay capacity.

[0545] For example, the terminal can calculate both the subgroup index for Capa1 and the subgroup index for Capa2.

[0546] For example, a terminal can select and use a subgroup index corresponding to its capabilities.

[0547] Method 2. A method of first checking the terminal's wake delay capability and assigning only one subgroup index corresponding to that capability.

[0548] For example, the capabilities of the terminal can be verified first.

[0549] For example, a single subgroup index can be determined by applying subgroup assignment rules corresponding to the relevant capability.

[0550] The proposed method allows for the flexible setting of subgroup sizes optimized for each weather delay capability characteristic, thereby enabling the efficient utilization of system resources. Furthermore, it offers the advantage of enabling differentiated group allocation based on weather delay capabilities while maintaining compatibility with existing terminal group allocation methods.

[0551] According to one embodiment of the present disclosure [Method #9], a terminal capability report for different weather delays may be provided.

[0552] In order for a base station to effectively manage terminals with different weather delays, the terminal may report its weather delay to the base station in the form of a capability report. To this end, it may be considered to configure weather delay presets, such as 100ms, 200ms, 400ms, and 800ms, and to report the shortest weather delay among them that the terminal can support. Through this, the base station can perform the transmission timing of a low-power weather signal (e.g., LP-WUS) and the allocation of paging opportunities (e.g., PO) suitable for each terminal based on the weather delay information included in the terminal capability report received from the terminal.

[0553] For example, for terminals with a long wake-up delay, scheduling may be adjusted such that the transmission of the low-power wake-up signal (e.g., LP-WUS) is advanced, or the paging opportunity (e.g., PO) of the terminal is delayed. This ensures that all terminals can wake up at an appropriate timing after receiving the low-power wake-up signal (e.g., LP-WUS) and receive paging.

[0554] As an alternative approach, for example, it may be considered that the terminal reports that one or more of the configured wake-up delay presets are supported. For example, the terminal may classify and report wake-up delays according to predefined power saving gain requirements. For example, for a certain power saving gain requirement, the terminal reports the minimum wake-up delay that satisfies that power saving gain requirement, and multiple power saving gain requirements may be configured.

[0555] As another example, the terminal may report two wake-up delays: one at which the highest power saving gain can be achieved, and the shortest possible wake-up delay. As yet another example, the terminal may simply indicate multiple wake-up delays at which a paging opportunity (e.g., PO) can be received. This prevents the setting of an unnecessarily long time offset when the base station intends to set a longer low-power wake-up signal-to-paging opportunity offset (e.g., LO-PO offset) to reduce power consumption within the network.

[0556] If a terminal reports multiple weather delays as terminal capabilities, it may be necessary to clearly define terminal operations. For example, a terminal that reports N weather delays may monitor N corresponding paging opportunities (e.g., POs).

[0557] For example, the fact that a terminal reports multiple terminal capabilities may mean that it receives multiple paging opportunities (e.g., PO) corresponding to each wake-up delay, or that it can selectively receive only any of the paging opportunities (e.g., PO) depending on the terminal's sleep state and the time length until the paging opportunity (e.g., PO) to be monitored.

[0558] Conversely, the terminal may receive a low-power wake-up signal (e.g., LP-WUS) and / or monitor a paging opportunity (e.g., PO) only if the time interval between the received or set low-power wake-up signal (e.g., LP-WUS) and the paging opportunity to be monitored (e.g., PO) is greater than the smallest value among the reported wake-up delays. For example, to this end, the base station may set radio resource control (e.g., RRC) parameters via upper layer signaling or a system information block (e.g., SIB) to trigger the terminal to receive multiple paging opportunities (e.g., PO) based on capability reporting.

[0559] For example, if the parameter is set, the terminal may receive a random paging opportunity (e.g., PO) based on one or more reported wake delays, and if not set, it may determine whether to receive a low-power wake signal (e.g., LP-WUS) and a paging opportunity (e.g., PO) based on the smallest value among the reported wake delays.

[0560] For example, if a terminal reports multiple wake delays as terminal capabilities, to use Method #8, the terminal may construct a terminal subgroup index based only on the smallest value among the wake delays it has reported. Alternatively, for example, terminals that support only wake delays greater than a specific value may be configured as a separate terminal subgroup. If a terminal reports different wake delays for multiple power gain requirements, a specific power gain requirement may be provided as a criterion for determining the subgroup. This may be a specific power gain requirement supported by all terminals that support a low-power wake signal (e.g., LP-WUS), a specific power gain requirement that is predefined, or a specific power gain requirement that is pre-set by the base station via upper layer signaling or a system information block (e.g., SIB).

[0561] According to one embodiment of the present disclosure, [Method #9-1], a method for handling different weather delays may be provided.

[0562] For example, processing methods based on the terminal's wake delay capabilities can be defined according to various situations. Basically, cases where the wake delay supported by the terminal is not set, where there are two or more, and cases where it is not set but can be separately instructed by the base station later can be considered. Additionally, situations such as network load conditions and the configuration of multiple low-power wake signals (e.g., LP-WUS) can also be considered.

[0563] Possible terminal actions depending on the situation include, for example, assuming different sleep states, determining the payload configuration for low-power wake-up signal opportunities (e.g., LO), actions related to low-power synchronization signals (e.g., LP-SS), other fallback actions, and changes in monitoring actions. Additionally, actions such as dynamic wake-up delay adjustment, monitoring of multiple paging opportunities (e.g., PO), and selective ignoring of low-power wake-up signals (e.g., LP-WUS) may be considered.

[0564] Various embodiments can be configured through combinations of such situations and possible terminal operations. For example, in Method No. 9-1, various embodiments can be configured through combinations of various situations and possible terminal operations. These combinations can be defined as follows.

[0565] 1. When one supported weather delay is set on the terminal

[0566] For example, the terminal can receive low-power wake signal opportunities (e.g., LO) and paging opportunities (e.g., PO) (or base station-to-terminal physical control channel (e.g., PDCCH) monitoring opportunities (e.g., MO)) based on the configured wake delay.

[0567] 2. If a weather delay supported by the terminal is not set

[0568] For example, the terminal can use the shortest supported wake delay.

[0569] In this case, for example, if the shortest weather delay supported by the terminal is smaller than any available weather delay set by the base station, the available weather delay set by the base station may be determined to be supported.

[0570] If the available wake-up delay set by the base station is shorter than the shortest wake-up delay that the terminal can support, a method may be adopted in which the terminal monitors the next paging opportunity (e.g., PO) of the originally received paging opportunity (e.g., PO) after receiving a low-power wake-up signal opportunity (e.g., LO).

[0571] Alternatively, as a fallback operation, for example, the terminal may not perform low-power wake-up signal reception (e.g., LP-WUS) reception and may perform paging operation based on conventional discontinuous reception (e.g., DRX).

[0572] If a low-power wake-up signal (e.g., LP-WUS) indicates the wake-up of the entire group of terminals rather than a specific group of terminals, the terminal may attempt to receive the next paging opportunity (e.g., PO) whenever possible. For example, a method may be adopted in which the terminal secures the wake-up delay by monitoring the next paging opportunity (e.g., PO) to be received after the originally indicated / set wake-up delay following the low-power wake-up signal opportunity (e.g., LO). Alternatively, the terminal may attempt to arbitrarily receive a paging opportunity (e.g., PO) after a supported wake-up delay following the low-power wake-up signal opportunity (e.g., LO).

[0573] For example, if the terminal supports two or more weather delays, the terminal may arbitrarily select an appropriate weather delay according to the current situation.

[0574] In this case, the base station can perform low-power wake signal (e.g., LP-WUS) transmission and paging base station-to-terminal physical control channel (e.g., PDCCH) transmission by considering all cases where the terminal selects each wake delay.

[0575] For example, the terminal can arbitrarily select a wake-up delay to maintain a sleep state and secure power saving effects.

[0576] Alternatively, for example, the terminal may select a shorter wake-up delay to secure a delay time among the set wake-up delays.

[0577] Alternatively, for example, the terminal may select a preferred and supported wake-up delay among the configured wake-up delays. To this end, the supported wake-up delays and the preferred wake-up delay among them may be selected based on the terminal's capabilities. For example, the wake-up delay preferred by the terminal may be selected by considering the terminal's power consumption and the sleep states supported by that wake-up delay.

[0578] For example, depending on the selected wake delay, the terminal may assume a different low-power wake signal (e.g., LP-WUS) payload configuration and change the low-power synchronization signal (e.g., LP-SS) reception period.

[0579] More specifically, for example, a short low-power synchronization signal (e.g., LP-SS) reception period may be applied during a short wake-up delay, and a longer low-power synchronization signal (e.g., LP-SS) reception period may be applied during a long wake-up delay. To this end, the base station may set multiple low-power synchronization signal (e.g., LP-SS) periods for the terminal. Alternatively, for example, for a long low-power synchronization signal (e.g., LP-SS) reception period, the terminal may selectively receive some of the randomly transmitted low-power synchronization signals (e.g., LP-SS).

[0580] More specifically, for example, if a weather delay that the terminal can support is not set but can be separately instructed, the terminal may perform an action such as "when a weather delay that the terminal can support is not set" until a separate weather delay that can be supported is instructed.

[0581] For example, if a wake-up delay is indicated on a low-power wake-up signal (e.g., LP-WUS) payload, the terminal can determine and receive the location of the low-power wake-up signal opportunity (e.g., LO). To do this, any terminal may assume a reference wake-up delay. The reference wake-up delay may be predefined or set by the base station's upper layer signaling.

[0582] In this case, for example, the terminal may check for a wake-up delay indicated on the low-power wake-up signal (e.g., LP-WUS) payload and, depending on whether the wake-up delay is supported, continue or stop the low-power wake-up signal (e.g., LP-WUS) operation and wait for the next low-power wake-up signal opportunity (e.g., LO).

[0583] If, for example, a low-power wake-up signal (e.g., LP-WUS) indicates the wake-up of the entire group of terminals rather than a specific group of terminals, the terminal may attempt to receive the next paging opportunity (e.g., PO) as much as possible, regardless of the indicated wake-up delay. For example, a method may be adopted in which the terminal secures the wake-up delay by monitoring the next paging opportunity (e.g., PO) to be received after the originally indicated / set wake-up delay after receiving the low-power wake-up signal opportunity (e.g., LO). Alternatively, the terminal may attempt to arbitrarily receive a paging opportunity (e.g., PO) after a supported wake-up delay after receiving the low-power wake-up signal opportunity (e.g., LO).

[0584] According to one embodiment of the present disclosure [Method #10], a weather delay set by a base station (e.g., gNB) may be provided.

[0585] In this method, various methods may be considered for the base station to explicitly specify a wake-up delay. This may be because, from the perspective of a network vendor, using a random wake-up delay when transitioning the terminal to an idle / inactive state may be more efficient than providing multiple low-power wake-up signal opportunities (e.g., LO).

[0586] First, an override method through system information block (e.g., SIB) and radio resource control (e.g., RRC) disconnection can be considered. The base station broadcasts a default wake-up delay value through the system information block (e.g., SIB), but for individual terminals that have connected to the network once, a method of overriding through a radio resource control (e.g., RRC) disconnection message can be considered. For example, a default wake-up delay of 200ms is set in the system information block (e.g., SIB), and for a specific terminal, it can be overridden to 300ms through a radio resource control (e.g., RRC) disconnection message.

[0587] Next, a method of indicating a wake-up delay along with the low-power wake-up signal (e.g., LP-WUS) can be considered. This can be implemented by using a bitmap, code point, or direct value on the low-power wake-up signal (e.g., LP-WUS) payload.

[0588] For example, in the bitmap method, a bitmap for predefined wake delay values ​​can be included in the low-power wake signal (e.g., LP-WUS).

[0589] For example, in the code point method, a specific code point value can be mapped to a wake delay and included in a low-power wake signal (e.g., LP-WUS).

[0590] For example, in a method using direct values, simplified wake delay values ​​can be directly included in the low-power wake signal (e.g., LP-WUS). In other words, the location of the paging opportunity (e.g., PO) that requires monitoring after receiving the low-power wake signal opportunity (e.g., LO) can be explicitly indicated on the low-power wake signal (e.g., LP-WUS).

[0591] In addition, a method of indirectly indicating a weather delay as follows can also be considered.

[0592] The method may be implemented, for example, by instructing the terminal to receive a paging opportunity (e.g., PO) other than the determined paging opportunity (e.g., PO) (e.g., the next or the next next paging opportunity (e.g., PO) instead of the determined paging opportunity (e.g., PO)) through a low-power wake-up signal (e.g., LP-WUS) message, or by setting an alternative paging opportunity (e.g., PO) or a paging opportunity (e.g., PO) offset.

[0593] For example, in a method instructing a terminal to receive a paging opportunity (e.g., PO) other than the determined paging opportunity (e.g., PO), a longer wake-up delay may be indirectly set by instructing the next paging opportunity (e.g., PO) following the currently determined paging opportunity (e.g., PO).

[0594] Alternatively, for example, by adding a specific bit or field to a low-power wake signal (e.g., LP-WUS), it may be indicated how many paging opportunities (e.g., PO) after the currently determined paging opportunity (e.g., PO) will be received. Using this method, the wake delay can be flexibly adjusted without significantly changing the existing paging opportunity (e.g., PO) structure.

[0595] For example, in an alternative paging opportunity (e.g., PO) or paging opportunity (e.g., PO) offset setting method, an alternative paging opportunity (e.g., PO) location to be used or a paging opportunity (e.g., PO) offset to be determined when a wake delay not supported by the terminal is assigned may be predefined or set through upper layer signaling of the base station. This may be to support different wake delays of terminals by dividing them into two paging opportunities (e.g., PO).

[0596] Through these various methods, base stations can flexibly set wake-up delays based on network conditions and terminal characteristics. For example, power consumption can be reduced by setting a longer wake-up delay during low-traffic periods, while faster responsiveness can be ensured by setting a shorter delay during high-traffic periods. Furthermore, since wake-up delays can be individually adjusted based on the terminal's battery status or service priority, a balance can be struck between the efficient use of network resources and the terminal's power management.

[0597] The present disclosure describes a method for allocating a low power wake-up signal opportunity (e.g., LO) for transmitting a low power wake-up signal (e.g., LP-WUS; Low power wake-up signal) to a terminal based on a paging opportunity (e.g., PO) to be used for receiving a pre-configured paging message.

[0598] For effective reception of a low-power wake-up signal (e.g., LP-WUS), it may be important to adjust the number of terminals receiving a single low-power wake-up signal (e.g., LP-WUS) reception opportunity, such as having different terminals receive the low-power wake-up signal (e.g., LP-WUS) together or dividing the reception among multiple low-power wake-up signal (e.g., LP-WUS) reception opportunities. If too many terminals receive a single low-power wake-up signal (e.g., LP-WUS), a large number of terminals may falsely wake up, and if too many low-power wake-up signal (e.g., LP-WUS) reception opportunities are given to terminals, the effect of reducing low-power wake-up signal (e.g., LP-WUS) power consumption may be reduced.

[0599] In the present disclosure, a method for controlling the number of low-power wake signal (e.g., LP-WUS) reception opportunities per paging opportunity (e.g., PO) is discussed by a base station setting an offset for terminals and the terminal selecting and applying it.

[0600] According to existing technology, a terminal can be called via a paging message when the terminal is in an idle or inactive state. In a paging system, it can be determined when the terminal should receive a paging message by using the concepts of a paging frame (e.g., PF) and a paging opportunity (e.g., PO).

[0601] For example, a paging frame (e.g., PF) can be a radio frame in which a paging message can be transmitted.

[0602] For example, a paging opportunity (e.g., PO) may be a specific subframe within a paging frame where a paging message is transmitted.

[0603] Low-power wake-up signal (e.g., LP-WUS) technology is designed to operate in conjunction with these existing paging systems. Low-power wake-up signals (e.g., LP-WUS) can be transmitted in time slots called low-power wake-up signal opportunities (e.g., LO), and these low-power wake-up signal opportunities (e.g., LO) can be determined through their relationship with existing paging frames (e.g., PF) and paging opportunities (e.g., PO).

[0604] The location of low-power wake signal opportunities (e.g., LO) is typically determined by applying an offset to the paging frames (e.g., PF) and paging opportunities (e.g., PO) of the existing paging system. This method may have the following characteristics.

[0605] Low-power wake signal opportunities (e.g., LO) may be designed to occur a certain time earlier than paging opportunities (e.g., PO). This can be expressed by the following formula:

[0606] T_LO = (T_PF or T_PO) - _offset

[0607] Here, T_LO may be the start time of a low-power wake signal (e.g., LP-WUS) opportunity, T_PO may be the start time of a paging opportunity, and T_PF may be the start time of a paging frame, _offset can be the sum of preset offset values.

[0608] For example, this offset value ( _offset) is configured as a network parameter and can provide sufficient time for the terminal to activate the main radio and prepare to receive actual paging messages after receiving a low-power wake-up signal (e.g., LP-WUS).

[0609] Various methods are being discussed to provide terminals with the opportunity to transmit low-power wake-up signals (e.g., LP-WUS). In particular, a method has been proposed in which multiple offsets are set by considering the wake-up delay characteristics between terminals, and a terminal selects one offset based on its wake-up delay capability.

[0610] This approach can aim to improve system efficiency by selecting an offset tailored to the characteristics of the terminal. Existing proposals primarily focus on selecting an offset based on the terminal's own wake-up delay capabilities. For example, the terminal can select one of several preset offsets according to its characteristics.

[0611] In contrast to this, the present disclosure proposes a method in which an offset or offset group is set separately from a paging occasion (PO) or paging frame (e.g., PF) monitored by a terminal, and the terminal selects one offset or offset group according to the paging occasion (e.g., PO) / paging frame (e.g., PF) it monitors.

[0612] This may be a new approach that allows the network to more flexibly control the allocation of low-power wake signal opportunities (e.g., LO) independently of the wake delay capabilities of the terminal. According to various embodiments of the present disclosure, by setting an offset based on paging opportunities (e.g., PO) / paging frames (e.g., PF), it may be possible for the network to effectively control the number of terminals receiving low-power wake signals (e.g., LP-WUS) for a specific paging opportunity (e.g., PO) / paging frame (e.g., PF) and optimize system performance.

[0613] According to one embodiment of the present disclosure, a method may be provided for determining a low-power wake signal opportunity (e.g., LO) by separately setting an offset or offset group on a paging occasion (PO) or paging frame (e.g., PF) monitored by a terminal, and by selecting one offset or offset group according to the paging occasion (e.g., PO) / paging frame (e.g., PF) monitored by the terminal.

[0614] In the present disclosure, for example, a low-power weather signal opportunity (e.g., LO) may be a concept comprising one or more low-power weather signal monitoring opportunities (e.g., LMO; LP-WUS monitoring occasions). In other words, one low-power weather signal monitoring opportunity (e.g., LMO) may be replaced by one low-power weather signal opportunity (e.g., LO), or a group of low-power weather signal monitoring opportunities (e.g., LMO) consisting of one or more low-power weather signal monitoring opportunities (e.g., LMO) may be replaced by a low-power weather signal opportunity (e.g., LO).

[0615] In the present disclosure, a low-power weather signal monitoring opportunity (e.g., LMO) is a minimum time unit in which a terminal monitors a low-power weather signal (e.g., LP-WUS) signal, and a low-power weather signal opportunity (e.g., LO) may mean a larger time range including one or more low-power weather signal monitoring opportunities (e.g., LMO).

[0616] For example, determining the location of a low-power weather signal opportunity (e.g., LO) may determine the location of the first low-power weather signal monitoring opportunity (e.g., LMO) within the low-power weather signal opportunity (e.g., LO) or the location of the last low-power weather signal monitoring opportunity (e.g., LMO) within the low-power weather signal opportunity (e.g., LO). For example, determining the starting location of the first low-power weather signal monitoring opportunity (e.g., LMO) within the low-power weather signal opportunity (e.g., LO) may determine the starting location of a single low-power weather signal opportunity (e.g., LO).

[0617] For example, a base station may set a set of parameters consisting of one or more parameters through higher-layer signaling, such as a System Information Block (e.g., SIB), to set a low-power wake-up signal opportunity (e.g., LO) location for a terminal, and to determine a low-power wake-up signal opportunity (e.g., LO) offset, which represents the location of a low-power wake-up signal opportunity (e.g., LO) relative to each paging opportunity (e.g., PO) determined for the terminal to monitor. The terminal may determine the low-power wake-up signal opportunity (e.g., LO) offset by considering the set of parameters set by the base station, the terminal's capabilities, and a predefined value.

[0618] For example, among the set of parameters set by the base station, the terminal can determine one of the parameters by considering the terminal's capabilities. For example, one parameter can be selected based on the terminal's weather delay capability.

[0619] For example, if multiple methods are used to determine a single low-power wake signal opportunity (e.g., LO) offset, the offset may be determined as the sum of one or more elements. For example, the offset T is determined as T = a + b1 + b2 + b3 + c + d, where a is a value defined as a capacity, b1 is a value in frames indicated by a system information block (e.g., SIB), b2 is a value in slots indicated by a system information block (e.g., SIB), b3 is a value in symbols indicated by a system information block (e.g., SIB), c is a preset time length, and d may be 0 if not set in the paging early indication (e.g., PEI), a preset value if the paging early indication (e.g., PEI) is set, or a value obtained through the pei-FrameOffset or firstPDCCH-MonitoringOccasionOfPEI-O parameter included in the paging early indication (e.g., PEI) reception setting.

[0620] For example, the terminal may determine the location of a low-power wake-up signal opportunity (e.g., LO) by applying a determined low-power wake-up signal opportunity (e.g., LO) offset to the beginning of a paging frame (e.g., PF) or to the beginning of a paging opportunity (e.g., PO). For example, the first low-power wake-up signal opportunity (e.g., LO) may be determined by applying the low-power wake-up signal opportunity (e.g., LO) offset to the beginning of a paging frame (e.g., PF) used to determine the paging opportunity (e.g., PO) to be received.

[0621] In the present disclosure, the following terminal and base station operations are proposed for a process of determining a low-power wake signal opportunity (e.g., LO) location based on a paging opportunity (e.g., PO) / paging frame (e.g., PF) location.

[0622] According to one embodiment of the present disclosure [Method #11], a plurality of offsets for different units may be provided.

[0623] For example, when a base station sets a parameter or set of parameters used to determine a low-power wake signal opportunity (e.g., LO) offset for a terminal, various types of offsets may be configured. For example, a frame-unit offset, a slot-unit offset, or a symbol-unit offset may be set from the base station to the terminal via a system information block (e.g., SIB).

[0624] For example, a base station can configure multiple offset sets, and each set can consist of (frame, slot, symbol) offsets. For example, a base station can set multiple offset sets as follows.

[0625] Offset set #1: {Frame offset #1, Slot offset #1, Symbol offset #1}

[0626] Offset Set #2: {Frame Offset #2, Slot Offset #2, Symbol Offset #2}

[0627] ...

[0628] Offset set #N: {Frame offset #N, Slot offset #N, Symbol offset #N}

[0629] As another example, a base station can configure multiple offset sets, and each set can consist of offsets of a specific time unit. For example, a base station can set multiple offset sets as follows.

[0630] Frame Offset Set (Frame_Offset_Set): Set of parameters related to frame-unit offsets {Frame Offset #1, Frame Offset #2, Frame Offset #3, ...}

[0631] Slot Offset Set (Slot_Offset_Set): Set of parameters related to slot-unit offsets {Slot Offset #1, Slot Offset #2, Slot Offset #3, ...}

[0632] Symbol Offset Set (Symbol_Offset_Set): Set of parameters related to symbol-unit offsets {Symbol Offset #1, Symbol Offset #2, Symbol Offset #3, ...}

[0633] The terminal can calculate the final low-power wake-up signal opportunity (e.g., LO) offset by selecting a set of parameters applied to the corresponding paging opportunity (e.g., PO) for each time unit and combining them. In this way, the base station can control the low-power wake-up signal opportunity (e.g., LO) more finely and optimize the terminal's reception performance. For example, the terminal can determine the low-power wake-up signal opportunity (e.g., LO) offset in the following manner based on its wake-up delay terminal capability.

[0634] Option 1. Determining the optimal offset through a composite unit offset set

[0635] 1. The terminal can check its weather delay capability.

[0636] 2. For each offset set #X received from the base station, the (frame, slot, symbol) offset combination of the set can be evaluated to see how well it matches the terminal's wake-up delay capability. More specifically, the terminal can select the shortest offset combination among offset combinations longer than its wake-up delay capability.

[0637] 3. Based on the evaluation results, the most suitable offset set #X is selected, and the offset values ​​(frame, slot, symbol) of the set can be used to set the low-power wake signal opportunity (e.g., LO).

[0638] Option 2. Determining the optimal offset through a set of offsets by unit

[0639] 1. The terminal can check its wake-up delay capability and, accordingly, select one of the frame-unit offsets. For example, a terminal with a short wake-up delay capability can select a small frame offset, and a terminal with a long wake-up delay capability can select a large frame offset. More specifically, the terminal can select the shortest value among the frame-unit offsets that are longer than its wake-up delay capability.

[0640] 2. The terminal can determine slot and symbol offsets corresponding to a location configured with the selected frame offset, or having an index equal to the selected frame offset.

[0641] Option 3. Frame-unit offset is determined based on terminal capabilities, then another method is applied.

[0642] 1. The terminal can check its wake-up delay capability and, accordingly, select one of the frame-unit offsets. For example, a terminal with a short wake-up delay capability can select a small frame offset, and a terminal with a long wake-up delay capability can select a large frame offset. More specifically, the terminal can select the shortest value among the frame-unit offsets that are longer than its wake-up delay capability.

[0643] 2. The slot and symbol offsets after the selected frame offset can be determined through other methods proposed. For example, the slot offset or symbol offset can be determined by using the offset method per paging opportunity (e.g., PO) described in Method #11.

[0644] According to one embodiment of the present disclosure, a terminal may first apply a frame-unit offset from a paging frame (e.g., PF) to determine a frame in which a low-power wake-up signal opportunity (e.g., LO) is configured, and to determine a low-power wake-up signal opportunity (e.g., LO) frame, and may determine a slot or symbol offset configured to determine the position of the low-power wake-up signal opportunity (e.g., LO) in the selected low-power wake-up signal opportunity (e.g., LO) frame. In this case, the slot or symbol offset configured as in Option 3 may be configured per paging frame (e.g., PF) received by the terminal or per paging opportunity (e.g., PO) within a paging frame (e.g., PF) received by the terminal.

[0645] According to one embodiment of the present disclosure [Method #12], a plurality of offsets for different paging opportunities (e.g., PO) within a paging frame (e.g., PF) may be provided.

[0646] For example, when a base station sets a parameter or set of parameters used to determine a low-power wake signal opportunity (e.g., LO) offset for a terminal, a parameter or set of parameters applicable to each paging opportunity (e.g., PO) within a paging frame (e.g., PF) may be set separately. For example, if N paging opportunities (e.g., PO) can be configured within a paging frame (e.g., PF), the base station may set M sets of parameters (M N) can be set separately.

[0647] For example, the terminal may assign an index to each paging opportunity (e.g., PO) in chronological order according to the location of the paging opportunity (e.g., PO) configured within the paging frame (e.g., PF), and determine the set of parameters to be applied according to the index of the paging opportunity (e.g., PO) to be received.

[0648] Alternatively, for example, a set of parameters to be applied may be determined based on an assigned terminal identifier in a manner similar to the method of selecting a paging opportunity (e.g., PO) within a paging frame (e.g., PF). For example, if two paging opportunities (e.g., PO) are configured within a paging frame (e.g., PF) and two sets of parameters are set, a terminal receiving the first paging opportunity (e.g., PO) within the paging frame (e.g., PF) may select the first set of parameters.

[0649] If two paging opportunities (e.g., PO) are configured within a paging frame (e.g., PF) and one set of parameters is set to determine the offset of a low-power wake signal opportunity (e.g., LO), then all terminals within that paging frame (e.g., PF) can use the same set of parameters.

[0650] For example, a base station may broadcast a set of parameters for each paging opportunity (e.g., PO) through a system information block (e.g., SIB), and a terminal may select a set of parameters to be applied to the corresponding paging opportunity (e.g., PO) based on its received paging opportunity (e.g., PO) index or identifier.

[0651] The proposed method may facilitate having different low-power wake signal opportunities (e.g., LO) for each paging opportunity (e.g., PO) within a paging frame (e.g., PF). Through this, the base station can configure separate low-power wake signal opportunities (e.g., LO) for each paging opportunity (e.g., PO) within the same paging frame (e.g., PF) while setting an offset applied based on the paging frame (e.g., PF).

[0652] If, for example, the number of parameter sets (M) set by the base station is less than the number of paging opportunities (e.g., PO) (N) within a paging frame (e.g., PF) (M < N), the terminal can select parameter sets in the following way.

[0653] For example, the terminal can calculate the remainder of dividing its received paging opportunity (e.g., PO) index by M and select a parameter set corresponding to that remainder. For example, when N=5 and M=2, parameter set 0 may be used for paging opportunity (e.g., PO) 0, paging opportunity (e.g., PO) 2, and paging opportunity (e.g., PO) 4, and parameter set 1 may be used for paging opportunity (e.g., PO) 1 and paging opportunity (e.g., PO) 3.

[0654] For example, paging opportunities (e.g., PO) within a paging frame (e.g., PF) are divided into M groups, and the same set of parameters may be used for paging opportunities (e.g., PO) belonging to each group. For example, the grouping criteria may be determined by considering various factors such as terminal identifiers. For example, when N=5 and M=2, consecutive ceil(N / M) or floor(N / M) paging opportunities (e.g., PO) or max(1, floor(N / M)) paging opportunities (e.g., PO) may be included in one group.

[0655] For example, the proposed method can be performed separately from the process of the terminal selecting parameters based on wake-up delay capabilities. For example, in order for the terminal to determine a low-power wake-up signal opportunity (e.g., LO) offset, through the proposed method, one or more parameters or sets of parameters for paging opportunities (e.g., PO) received by the terminal are first selected, and from the selected one or more parameters or sets of parameters, one parameter or set of parameters can be selected based on wake-up delay capabilities.

[0656] For example, the proposed method may be applied only to a specific set of parameters. For example, terminals within a paging frame (e.g., PF) may select a frame-unit offset based on wake delay capabilities and select a symbol-unit offset through the proposed method.

[0657] According to one embodiment of the present disclosure [Method #13], a plurality of offsets for different paging opportunities (e.g., PO) within a plurality of paging frames (e.g., PF) may be provided.

[0658] For example, when a base station sets a parameter or set of parameters used to determine a low-power wake-up signal opportunity (e.g., LO) offset for a terminal, a case may be considered where one low-power wake-up signal opportunity (e.g., LO) corresponds to two or more paging frames (e.g., PF). In this case, the number (N) of paging frames (e.g., PF) constituting the low-power wake-up signal opportunity (e.g., LO) may be set, and the base station may separately set an offset or set of parameters to be applied to each of the N paging frames (e.g., PF).

[0659] According to one embodiment of the present disclosure, the start time of the first paging frame (eg, PF) among the N paging frames (eg, PF) set can be used as a reference point for the entire low-power wake signal opportunity (eg, LO). For example, the configured offset can be expressed as a value relative to the start time of the first paging frame (eg, PF), regardless of the paging frame (eg, PF) of the paging opportunity (eg, PO) actually received by the terminal.

[0660] For example, if the start time of the first paging frame (e.g., PF) is set to 0 and the offset for the second paging frame (e.g., PF) is -10ms, the actual low-power wake-up signal (e.g., LP-WUS) transmission time of the second paging frame (e.g., PF) can be 10ms prior to the start time of the first paging frame (e.g., PF).

[0661] Additionally, for example, since paging frames (e.g., PF) exist consecutively within a discontinuous reception (e.g., DRX) cycle, the terminal and the base station can group N frames sequentially from the beginning of the discontinuous reception (e.g., DRX) cycle to determine the actual N paging frames (e.g., PF) and determine which position of its paging frame (e.g., PF) it is within the group. The terminal can identify the position (index within the group) of the paging frame (e.g., PF) to which it belongs within the current discontinuous reception (e.g., DRX) cycle and apply a corresponding offset according to that index.

[0662] For example, the terminal knows the sequence of paging frames (e.g., PF) that constitute a low-power wake-up signal opportunity (e.g., LO) and can determine the timing of receiving a low-power wake-up signal (e.g., LP-WUS) by applying an offset corresponding to each paging frame (e.g., PF). For example, the base station can broadcast N paging frames (e.g., PF) and their respective offsets or parameter sets through a system information block (e.g., SIB), etc.

[0663] According to the present method, when a low-power wake signal opportunity (e.g., LO) requires a large amount of resources over time, by making multiple paging frames (e.g., PF) correspond to fewer low-power wake signal opportunities (e.g., LO) than paging frames (e.g., PF), the availability of low-power wake signals (e.g., LP-WUS) can be increased and the wireless resource overhead associated with supporting low-power wake signals (e.g., LP-WUS) can be reduced. This can enable efficient resource management on the network side.

[0664] The proposed method can be performed separately from the process in which the terminal selects parameters based on wake-up delay capabilities. For example, to determine a low-power wake-up signal opportunity (e.g., LO) offset, the terminal first selects one or more parameters or sets of parameters for a paging opportunity (e.g., PO) received by the terminal through the proposed method, and from the selected one or more parameters or sets of parameters, one parameter or set of parameters can be selected based on wake-up delay capabilities.

[0665] For example, the proposed method can be applied only to a specific set of parameters. For example, terminals within a paging frame (e.g., PF) can select a frame-unit offset based on wake delay capabilities and select a symbol-unit offset through the proposed method.

[0666] According to one embodiment of the present disclosure [Method #14], a plurality of offsets for different paging frames (e.g., PF) may be provided.

[0667] For example, when a base station sets a parameter or set of parameters used to determine a low-power wake-up signal opportunity (e.g., LO) offset for a terminal, a case may be considered where one low-power wake-up signal opportunity (e.g., LO) corresponds to two or more paging frames (e.g., PF). In the present method, similar to Method 13, it is assumed that a low-power wake-up signal opportunity (e.g., LO) is configured across multiple paging frames (e.g., PF), but all terminals receiving a paging opportunity (e.g., PO) within each paging frame (e.g., PF) use the same offset.

[0668] For example, a base station may set one offset or set of parameters for each of the N paging frames (e.g., PF) that constitute a low-power wake-up signal opportunity (e.g., LO). All paging opportunities (e.g., PO) within each paging frame (e.g., PF) share the offset assigned to that paging frame (e.g., PF), which may be applied when a terminal determines when to receive a low-power wake-up signal (e.g., LP-WUS).

[0669] According to the present method, a base station may control whether low-power wake-up signal opportunities (e.g., LO) between paging frames (e.g., PF) are received at the same location or at different locations. For example, by adjusting an offset value for each paging frame (e.g., PF), the base station may control low-power wake-up signals (e.g., LP-WUS) to be transmitted simultaneously or with a time delay in multiple paging frames (e.g., PF) within the same low-power wake-up signal opportunity (e.g., LO). This allows the system to be flexibly configured according to network conditions and terminal characteristics.

[0670] Additionally, for example, since paging frames (e.g., PF) exist consecutively within a discontinuous reception (e.g., DRX) cycle, the terminal and the base station can group N frames sequentially starting from the beginning of the discontinuous reception (e.g., DRX) cycle to determine the actual N paging frames (e.g., PF) and determine which position of their paging frame (e.g., PF) it is within the group. For example, the terminal can identify the position (index within the group) of the paging frame (e.g., PF) to which it belongs within the current discontinuous reception (e.g., DRX) cycle and apply a corresponding offset according to that index.

[0671] For example, the terminal knows the sequence of paging frames (e.g., PF) that constitute a low-power wake-up signal opportunity (e.g., LO) and can calculate the time of reception of a low-power wake-up signal (e.g., LP-WUS) by using offset information corresponding to each paging frame (e.g., PF). For example, the base station can broadcast N paging frames (e.g., PF) and their respective offset information through a system information block (e.g., SIB), etc.

[0672] This method can enable effective reception of low-power wake-up signals (e.g., LP-WUS) even when low-power wake-up signal opportunities (e.g., LO) are distributed across multiple paging frames (e.g., PF) while reducing implementation complexity. In particular, this method has the advantage that a base station can coordinate the transmission location of low-power wake-up signals (e.g., LP-WUS) between paging frames (e.g., PF).

[0673] The proposed method can be performed separately from the process in which the terminal selects parameters based on wake-up delay capabilities. For example, to determine a low-power wake-up signal opportunity (e.g., LO) offset, the terminal first selects one or more parameters or sets of parameters for a paging opportunity (e.g., PO) received by the terminal through the proposed method, and from the selected one or more parameters or sets of parameters, one parameter or set of parameters can be selected based on wake-up delay capabilities.

[0674] For example, the proposed method may be applied only to a specific set of parameters. For example, terminals within a paging frame (e.g., PF) may select a frame-unit offset based on wake delay capabilities and select a symbol-unit offset through the proposed method.

[0675] According to one embodiment of the present disclosure [Method #15], a low-power weather signal opportunity (e.g., LO) configuration and a low-power weather signal monitoring opportunity (e.g., LMO) scheduling based on a time division duplex (e.g., TDD) setting may be provided.

[0676] For example, the present method may aim to optimize the reception opportunity of a low-power wake-up signal (e.g., LP-WUS) by considering the terminal-to-base station link / base station-to-terminal link (e.g., UL / DL) configuration of a time-division duplex (e.g., TDD) wireless communication system. As previously described, a single low-power wake-up signal opportunity (e.g., LO) may be composed of multiple low-power wake-up signal monitoring opportunities (e.g., LMO).

[0677] As described above, a low-power wake signal opportunity (e.g., LO) may be a set of successive low-power wake signal (e.g., LP-WUS) monitoring opportunities defined by a beam, a set of different low-power wake signal (e.g., LP-WUS) messages (a set of different low-power wake signal (e.g., LP-WUS) messages), and a repetition count (repetition), etc.

[0678] For example, if a terminal receives information from a base station regarding the time division duplex (e.g., TDD) structure of the wireless communication system, or if the terminal receives from the base station the transmission direction of a specific slot / symbol via radio resource control (e.g., RRC) parameters (e.g., TDD-UL-DL-configurationCommon) configured in the current cell, the availability of each low-power wake signal monitoring opportunity (e.g., LMO) configured within a low-power wake signal opportunity (e.g., LO) may vary. For example, it may be difficult to receive a low-power wake signal (e.g., LP-WUS) in a symbol directed by the base station to a terminal-to-base station link (e.g., UL).

[0679] Similar to the configuration method of conventional paging opportunities (e.g., PO), the terminal can sequentially number (starting from 0) and monitor only the low-power weather signal monitoring opportunities (e.g., LMO) within the low-power weather signal opportunities (e.g., LO) that do not conflict with terminal-to-base station symbols (e.g., UL symbols). Therefore, in order for the terminal to receive N low-power weather signal monitoring opportunities (e.g., LMO), actual N valid low-power weather signal monitoring opportunities (e.g., LMO) may need to be secured by taking into account conflicts with terminal-to-base station symbols (e.g., UL symbols). For example, the terminal may postpone the occurrence of low-power weather signal monitoring opportunities (e.g., LMO) that conflict with terminal-to-base station symbols (e.g., UL symbols).

[0680] The transmission of low-power wake-up signals (e.g., LP-WUS) may require significant time-domain resources, considering the characteristics of the receiver and transmission method under consideration. Additionally, considering the paging frame (e.g., PF) / paging opportunity (e.g., PO) configuration of terminals, the amount of wireless resources consumed to provide a single low-power wake-up signal opportunity (e.g., LO) may be limited by the intervals between paging opportunities (e.g., PO) or paging frames (e.g., PF) within the cell. Therefore, this method proposes a method for scheduling low-power wake-up signal monitoring opportunities (e.g., LMO) by considering the characteristics of such time-division duplex (e.g., TDD) structures, and for postponing or dropping / puncturing monitoring opportunities (e.g., MO) as needed. More specifically, the following may be considered.

[0681] For example, if there is only one low-power weather signal monitoring opportunity (e.g., LMO) in a particular beam, monitoring opportunities (e.g., MO) that conflict with terminal-to-base station symbols (e.g., UL symbols) may be postponed. This may be to ensure that at least one low-power weather signal monitoring opportunity (e.g., LMO) is transmitted per beam.

[0682] For example, if there are many low-power wake signal monitoring opportunities (e.g., LMO) in a particular beam, monitoring opportunities (e.g., MO) that conflict with terminal-to-base station symbols (e.g., UL symbols) may be dropped or punctured so that the length of the entire low-power wake signal (e.g., LP-WUS) transmission space can be maintained.

[0683] Here, for example, if N low-power weather signal monitoring opportunities (e.g., LMOs) are configured for a terminal, the terminal may assume that a total of N low-power weather signal monitoring opportunities (e.g., LMOs) occur without considering whether there is a collision with terminal-to-base station symbols (e.g., UL symbols). In this case, low-power weather signal monitoring opportunities (e.g., LMOs) that collide with terminal-to-base station symbols (e.g., UL symbols) may not be received. This may be intended to ensure that the minimum time-domain resources are used when at least one transmission of a low-power weather signal monitoring opportunity (e.g., LMO) per beam can be guaranteed.

[0684] For example, to determine whether there are multiple low-power weather signal monitoring opportunities (e.g., LMOs) in a specific beam, only the number of repeated transmissions in which the same information is repeated may be considered. For example, even if there are multiple low-power weather signal monitoring opportunities (e.g., LMOs) in a single beam, if they consist only of low-power weather signal monitoring opportunities (e.g., LMOs) in which different information can be transmitted, monitoring opportunities (e.g., MOs) that conflict with terminal-to-base station symbols (e.g., UL symbols) may be postponed, or, for example, monitoring opportunities (e.g., MOs) that conflict with terminal-to-base station symbols (e.g., UL symbols) may be dropped or the corresponding symbols may be punctured only when there are two or more low-power weather signal monitoring opportunities (e.g., LMOs) in which the same information is transmitted in a single beam.

[0685] If the opportunity to monitor low-power wake-up signals (e.g., LMO) is continuously delayed, it may cause problems with the occurrence of low-power wake-up signal opportunities (e.g., LO) associated with other terminals. Therefore, it may be necessary to set a limit on the postponement operation.

[0686] For example, since the terminal cannot know the start time of the next low-power wake signal opportunity (e.g., LO), the base station may need to inform the terminal when to stop monitoring the low-power wake signal (e.g., LP-WUS) by explicitly indicating the maximum length of the low-power wake signal opportunity (e.g., LO). This may be conveyed via a system information block (e.g., SIB) or radio resource control (e.g., RRC) signal, etc.

[0687] For example, the maximum time range in which a low-power weather signal monitoring opportunity (e.g., LMO) can be configured within a low-power weather signal opportunity (e.g., LO) may be explicitly indicated through a base station's system information block (e.g., SIB) or radio resource control (e.g., RRC) message. The terminal may assume that a low-power weather signal monitoring opportunity (e.g., LMO) occurs only within that time range and may stop monitoring the low-power weather signal (e.g., LP-WUS) without receiving the low-power weather signal (e.g., LP-WUS) during low-power weather signal monitoring opportunities (e.g., LMO) outside of that time range.

[0688] Alternatively, for example, the maximum length of a low-power wake signal opportunity (e.g., LO) may be defined in advance. For example, the maximum length of a low-power wake signal opportunity (e.g., LO) may be defined as 1 frame.

[0689] Alternatively, for example, if a low-power wake-up signal opportunity (e.g., LO) can be configured for a number of paging frames (e.g., PF), the number of said paging frames (e.g., PF) may be considered as the maximum length of the low-power wake-up signal opportunity (e.g., LO). For example, if up to N paging frames (e.g., PF) can correspond to one low-power wake-up signal opportunity (e.g., LO), the maximum length of the low-power wake-up signal opportunity (e.g., LO) may be considered as N frames.

[0690] In a first aspect of the present disclosure, a method used by a terminal in a wireless communication system may be provided, comprising the step of performing an operation proposed in the present disclosure.

[0691] In a second aspect of the present disclosure, a terminal used in a wireless communication system may be provided, comprising: at least one processor; and at least one computer memory operably connected to the at least one processor and, when executed, causing the at least one processor to perform the operation proposed in the present disclosure.

[0692] In a third aspect of the present disclosure, a device for a terminal may be provided, comprising: at least one processor; and at least one computer memory operably connected to the at least one processor and, when executed, causes the at least one processor to perform the operation proposed in the present disclosure.

[0693] In a fourth aspect of the present disclosure, a computer-readable storage medium may be provided that includes at least one computer program that, when executed, causes at least one processor to perform the operation proposed in the present disclosure.

[0694] In a fifth aspect of the present disclosure, a method used by a base station in a wireless communication system may be provided, comprising the step of performing the operation proposed in the present disclosure.

[0695] In a sixth aspect of the present disclosure, a base station used in a wireless communication system may be provided, comprising: at least one processor; and at least one computer memory operably connected to the at least one processor and, when executed, causing the at least one processor to perform the operation proposed in the present disclosure.

[0696] Herein, the operations proposed in this disclosure may be described separately for convenience, but unless specifically stated otherwise, each operation may be combined with others.

[0697] A low-power wake-up signal (e.g., LP-WUS) is a signal that allows a terminal to monitor at low power while in a state where it does not monitor paging by default (idle state), and it includes an instruction to perform paging after a specific time interval from the time it is received. In existing designs related to low-power wake-up signals (e.g., LP-WUS), terminals were defined to report their wake-up delay in various ways, but all methods have a structural limitation in that they cannot reflect the non-linear increase / decrease in wake-up delay due to changes in the synchronization signal block (e.g., SSB) period.

[0698] In particular, although the synchronization signal block (e.g., SSB) period can be widely set to 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc., existing methods are defined to report only fixed values ​​(e.g., 80ms, 500ms, 900ms) or values ​​based on the main radio (e.g., MR) activation time, so the correlation between the actual synchronization time and the wake-up delay is not accurately reflected. As a result, it is difficult for the network to accurately determine the supported wake-up delay range of the terminal, which may lead to failure to receive low-power wake-up signals (e.g., LP-WUS) or unnecessary power consumption. Furthermore, since the entire wake-up delay value must be signaled for each terminal, overhead increases, and there is a problem of fragmentation of terminal capability for various combinations of terminal classes and synchronization signal block (e.g., SSB) periods.

[0699] According to one embodiment of the present disclosure, a method for reporting a weather delay capability based on a predefined table is proposed. For example, a terminal does not report its own weather delay value itself, but reports only one (column) index of Low / Mid / High (e.g., 0 / 1 / 2), and the network can calculate the weather delay by mapping the index to the synchronization signal block (e.g., SSB) period (5ms, 10ms, 20ms, 40ms, 80ms, 160ms) of the current service cell.

[0700] According to various embodiments of the present disclosure, by unifying weather delay reporting based on an index, the complexity of signaling between the terminal and the network can be minimized and terminal capability fragmentation can be eliminated. For example, since the network can calculate the weather delay using the same set of indices regardless of fluctuations in the synchronization signal block period, the accuracy of comparison with the low-power weather signal opportunity-paging opportunity (e.g., LO-to-PO) offset and determination of low-power weather signal (e.g., LP-WUS) availability can be significantly improved.

[0701] FIG. 15 illustrates a procedure of a method that can be performed by a first device according to one embodiment of the present disclosure. The embodiment of FIG. 15 may be combined with various embodiments of the present disclosure, and the description, function, procedure, suggestion, method, and / or operation of said embodiment may be omitted.

[0702] Referring to FIG. 15, in step S1510, the first device may transmit information related to the first device’s capability for a wake-up delay to a base station. For example, the information related to the capability for a wake-up delay may include at least one value related to a wake-up delay for each of at least one synchronization signal block periods, and the at least one value related to a wake-up delay may be 0, 1, or 2. In step S1520, the first device may receive a system information block from the base station, which includes i) a first synchronization signal block period and ii) a first low-power wake-up signal opportunity-paging opportunity offset. In step S1530, the first device may obtain a first wake-up delay based on the first synchronization signal block period and the at least one value related to a wake-up delay. In step S1540, the first device may monitor a low-power wake-up signal based on the fact that the first low-power wake-up signal opportunity-paging opportunity offset is not smaller than the first wake-up delay.

[0703] For example, based on the fact that the first low-power wake signal opportunity-paging opportunity offset is not smaller than the first wake delay, the paging opportunity may not be monitored.

[0704] For example, additionally, the first device can monitor the paging opportunity based on the first low-power wake signal opportunity-paging opportunity offset being smaller than the first wake delay.

[0705] For example, a representative synchronization signal period associated with a synchronization signal block period of less than 20ms among the at least one synchronization signal block period is determined to be 20ms, and a value associated with a synchronization signal block period of less than 20ms among the at least one values ​​associated with a wake-up delay can be determined as a value for the representative synchronization signal period.

[0706] For example, based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 2, the first wake-up delay may be 900ms.

[0707] For example, based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 2, the first wake-up delay may be 900ms.

[0708] For example, based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 0, the first wake-up delay is 130ms; based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 1, the first wake-up delay is 600ms; and based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 2, the first wake-up delay may be 1000ms.

[0709] For example, based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 0, the first wake-up delay is 250ms; based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 1, the first wake-up delay is 800ms; and based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 2, the first wake-up delay may be 1200ms.

[0710] For example, based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 0, the first wake-up delay is 490ms; based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 1, the first wake-up delay is 1200ms; and based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 2, the first wake-up delay may be 1600ms.

[0711] For example, additionally, the first device can derive the reception location of the low-power weather signal based on the ID (identifier) ​​of the first device. For example, monitoring of the low-power weather signal can be performed based on the reception location.

[0712] For example, the system information block may include a second low-power weather signal opportunity-paging opportunity offset.

[0713] For example, the first low-power wake signal opportunity-paging opportunity offset is greater than the second low-power wake signal opportunity-paging opportunity offset, and the first low-power wake signal opportunity-paging opportunity offset may be greater than the value obtained by adding the first wake delay to the value obtained by multiplying the first synchronization signal block period and the number of required receptions of the synchronization signal block.

[0714] The above-described embodiment may be applied to various devices described below. First, the processor (102) of the first device (100) may control the transceiver (106) to transmit information related to the capability of the first device (100) for a weather delay to the base station (300). For example, the information related to the capability for a weather delay may include at least one value related to a weather delay for each of at least one synchronization signal block cycle, and the at least one value related to a weather delay may be 0, 1, or 2. Then, the processor (102) of the first device (100) may control the transceiver (106) to receive a system information block from the base station (300) including i) a first synchronization signal block cycle and ii) a first low-power weather signal opportunity-paging opportunity offset. And, the processor (102) of the first device (100) can obtain a first wake-up delay based on the first synchronization signal block period and at least one value related to the wake-up delay. And, the processor (102) of the first device (100) can monitor a low-power wake-up signal based on the fact that the first low-power wake-up signal opportunity-paging opportunity offset is not smaller than the first wake-up delay.

[0715] According to one embodiment of the present disclosure, a first device may be provided. For example, the first device 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 the instructions being executed by the at least one processor, the first device may: transmit to a base station information regarding the capability of the first device for a wake-up delay, wherein the information regarding the capability for a wake-up delay includes at least one value related to a wake-up delay for each of at least one synchronization signal block periods, and the at least one value related to a wake-up delay is 0, 1, or 2; receive from the base station a system information block including i) a first synchronization signal block period and ii) a first low-power wake-up signal opportunity-paging opportunity offset; and obtain a first wake-up delay based on the first synchronization signal block period and the at least one value related to a wake-up delay; And based on the fact that the first low-power weather signal opportunity-phasing opportunity offset is not smaller than the first weather delay, the low-power weather signal can be monitored.

[0716] For example, based on the fact that the first low-power wake signal opportunity-paging opportunity offset is not smaller than the first wake delay, the paging opportunity may not be monitored.

[0717] For example, additionally, the above commands may cause the first device to monitor the paging opportunity based on the first low-power wake signal opportunity-paging opportunity offset being smaller than the first wake delay.

[0718] For example, a representative synchronization signal period associated with a synchronization signal block period of less than 20ms among the at least one synchronization signal block period is determined to be 20ms, and a value associated with a synchronization signal block period of less than 20ms among the at least one values ​​associated with a wake-up delay can be determined as a value for the representative synchronization signal period.

[0719] For example, based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 2, the first wake-up delay may be 900ms.

[0720] For example, based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 2, the first wake-up delay may be 900ms.

[0721] For example, based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 0, the first wake-up delay is 130ms; based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 1, the first wake-up delay is 600ms; and based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 2, the first wake-up delay may be 1000ms.

[0722] For example, based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 0, the first wake-up delay is 250ms; based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 1, the first wake-up delay is 800ms; and based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 2, the first wake-up delay may be 1200ms.

[0723] For example, based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 0, the first wake-up delay is 490ms; based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 1, the first wake-up delay is 1200ms; and based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 2, the first wake-up delay may be 1600ms.

[0724] For example, additionally, the above commands may cause the first device to derive the reception location of the low-power weather signal based on the ID (identifier) ​​of the first device. For example, monitoring of the low-power weather signal may be performed based on the reception location.

[0725] For example, the system information block may include a second low-power weather signal opportunity-paging opportunity offset.

[0726] For example, the first low-power wake signal opportunity-paging opportunity offset is greater than the second low-power wake signal opportunity-paging opportunity offset, and the first low-power wake signal opportunity-paging opportunity offset may be greater than the value obtained by adding the first wake delay to the value obtained by multiplying the first synchronization signal block period and the number of required receptions of the synchronization signal block.

[0727] According to one embodiment of the present disclosure, a processing device configured to control a first device may be provided. For example, the processing device 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 the instructions being executed by the at least one processor, the first device may: transmit to a base station information regarding the capability of the first device for a wake-up delay, wherein the information regarding the capability for a wake-up delay includes at least one value related to a wake-up delay for each of at least one synchronization signal block period, and the at least one value related to a wake-up delay is 0, 1, or 2; receive from the base station a system information block including i) a first synchronization signal block period and ii) a first low-power wake-up signal opportunity-paging opportunity offset; and obtain a first wake-up delay based on the first synchronization signal block period and the at least one value related to a wake-up delay; And based on the fact that the first low-power weather signal opportunity-phasing opportunity offset is not smaller than the first weather delay, the low-power weather signal can be monitored.

[0728] According to one embodiment of the present disclosure, a non-transient computer-readable storage medium recording commands may be provided. For example, when the commands are executed, the first device may cause a base station to transmit information regarding the capability of the first device for a wake-up delay, wherein the information regarding the capability for a wake-up delay includes at least one value related to a wake-up delay for each of at least one synchronization signal block period, and the at least one value related to a wake-up delay is 0, 1, or 2; receive from the base station a system information block including i) a first synchronization signal block period and ii) a first low-power wake-up signal opportunity-paging opportunity offset; obtain a first wake-up delay based on the first synchronization signal block period and the at least one value related to a wake-up delay; and monitor a low-power wake-up signal based on the fact that the first low-power wake-up signal opportunity-paging opportunity offset is not smaller than the first wake-up delay.

[0729] FIG. 16 illustrates a procedure of a method that can be performed by a second device according to one embodiment of the present disclosure. The embodiment of FIG. 16 may be combined with various embodiments of the present disclosure, and the description, function, procedure, suggestion, method, and / or operation of said embodiment may be omitted.

[0730] Referring to FIG. 16, at step S1610, the second device may receive information from the first device regarding the capability for the wake-up delay of the first device. For example, the information regarding the capability for the wake-up delay may include at least one value related to the wake-up delay for each of at least one synchronization signal block cycle, and the at least one value related to the wake-up delay may be 0, 1, or 2. At step S1620, the second device may transmit to the first device a system information block including i) a first synchronization signal block cycle and ii) a first low-power wake-up signal opportunity-paging opportunity offset.

[0731] For example, additionally, the second device may determine to transmit a low-power wake-up signal to the first device; and based on the decision to transmit the low-power wake-up signal to the first device, the system information block may be generated to include a first low-power wake-up signal opportunity-paging opportunity offset not smaller than a first wake-up delay. For example, the first wake-up delay may be determined based on the first synchronization signal block period and at least one value associated with the wake-up delay.

[0732] For example, based on the fact that the first low-power wake signal opportunity-paging opportunity offset is not smaller than the first wake delay, the paging opportunity may not be monitored.

[0733] For example, based on the fact that the first low-power wake signal opportunity-paging opportunity offset is smaller than the first wake delay, the paging opportunity can be monitored by the first device.

[0734] For example, a representative synchronization signal period associated with a synchronization signal block period of less than 20ms among the at least one synchronization signal block period is determined to be 20ms, and a value associated with a synchronization signal block period of less than 20ms among the at least one values ​​associated with a wake-up delay can be determined as a value for the representative synchronization signal period.

[0735] For example, based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 2, the first wake-up delay may be 900ms.

[0736] For example, based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 2, the first wake-up delay may be 900ms.

[0737] For example, based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 0, the first wake-up delay is 130ms; based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 1, the first wake-up delay is 600ms; and based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 2, the first wake-up delay may be 1000ms.

[0738] For example, based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 0, the first wake-up delay is 250ms; based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 1, the first wake-up delay is 800ms; and based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 2, the first wake-up delay may be 1200ms.

[0739] For example, based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 0, the first wake-up delay is 490ms; based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 1, the first wake-up delay is 1200ms; and based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 2, the first wake-up delay may be 1600ms.

[0740] For example, the reception location of the low-power weather signal can be derived by the first device based on the ID (identifier) ​​of the first device. For example, monitoring of the low-power weather signal can be performed based on the reception location.

[0741] For example, the system information block may include a second low-power weather signal opportunity-paging opportunity offset.

[0742] For example, the first low-power wake signal opportunity-paging opportunity offset is greater than the second low-power wake signal opportunity-paging opportunity offset, and the first low-power wake signal opportunity-paging opportunity offset may be greater than the value obtained by adding the first wake delay to the value obtained by multiplying the first synchronization signal block period and the number of required receptions of the synchronization signal block.

[0743] The above-described embodiment may be applied to various devices described below. First, the processor (202) of the second device (200) may control the transceiver (206) to receive information related to the capability for a wake-up delay of the first device (100) from the first device (100). For example, the information related to the capability for a wake-up delay may include at least one value related to a wake-up delay for each of at least one synchronization signal block cycle, and the at least one value related to a wake-up delay may be 0, 1, or 2. Then, the processor (202) of the second device (200) may control the transceiver (206) to transmit a system information block to the first device (100) that includes i) a first synchronization signal block cycle and ii) a first low-power wake-up signal opportunity-paging opportunity offset.

[0744] According to one embodiment of the present disclosure, a second device may be provided. For example, the second device 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 the instructions being executed by the at least one processor, the second device may be caused to: receive information from a first device regarding the capability for a wake-up delay of the first device, wherein the information regarding the capability for a wake-up delay includes at least one value related to a wake-up delay for each of at least one synchronization signal block periods, and the at least one value related to a wake-up delay is 0, 1, or 2; and transmit to the first device a system information block including i) a first synchronization signal block period and ii) a first low-power wake-up signal opportunity-paging opportunity offset.

[0745] For example, additionally, the commands may cause the second device to: determine to transmit a low-power wake-up signal to the first device; and, based on the decision to transmit the low-power wake-up signal to the first device, to generate the system information block to include a first low-power wake-up signal opportunity-paging opportunity offset not smaller than a first wake-up delay. For example, the first wake-up delay may be determined based on the first synchronization signal block period and at least one value associated with the wake-up delay.

[0746] For example, based on the fact that the first low-power wake signal opportunity-paging opportunity offset is not smaller than the first wake delay, the paging opportunity may not be monitored.

[0747] For example, based on the fact that the first low-power wake signal opportunity-paging opportunity offset is smaller than the first wake delay, the paging opportunity can be monitored by the first device.

[0748] For example, a representative synchronization signal period associated with a synchronization signal block period of less than 20ms among the at least one synchronization signal block period is determined to be 20ms, and a value associated with a synchronization signal block period of less than 20ms among the at least one values ​​associated with a wake-up delay can be determined as a value for the representative synchronization signal period.

[0749] For example, based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being less than 20ms and ii) the value related to the wake-up delay for the synchronization signal block period being less than 20ms being 2, the first wake-up delay may be 900ms.

[0750] For example, based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 0, the first wake-up delay is 70ms; based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 1, the first wake-up delay is 500ms; and based on i) the first synchronization signal period being 20ms and ii) the value related to the wake-up delay for the synchronization signal block period of 20ms being 2, the first wake-up delay may be 900ms.

[0751] For example, based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 0, the first wake-up delay is 130ms; based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 1, the first wake-up delay is 600ms; and based on i) the first synchronization signal period being 40ms and ii) the value related to the wake-up delay for the synchronization signal block period of 40ms being 2, the first wake-up delay may be 1000ms.

[0752] For example, based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 0, the first wake-up delay is 250ms; based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 1, the first wake-up delay is 800ms; and based on i) the first synchronization signal period being 80ms and ii) the value related to the wake-up delay for the synchronization signal block period of 80ms being 2, the first wake-up delay may be 1200ms.

[0753] For example, based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 0, the first wake-up delay is 490ms; based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 1, the first wake-up delay is 1200ms; and based on i) the first synchronization signal period being 160ms and ii) the value related to the wake-up delay for the synchronization signal block period of 160ms being 2, the first wake-up delay may be 1600ms.

[0754] For example, the reception location of the low-power weather signal can be derived by the first device based on the ID (identifier) ​​of the first device. For example, monitoring of the low-power weather signal can be performed based on the reception location.

[0755] For example, the system information block may include a second low-power weather signal opportunity-paging opportunity offset.

[0756] For example, the first low-power wake signal opportunity-paging opportunity offset is greater than the second low-power wake signal opportunity-paging opportunity offset, and the first low-power wake signal opportunity-paging opportunity offset may be greater than the value obtained by adding the first wake delay to the value obtained by multiplying the first synchronization signal block period and the number of required receptions of the synchronization signal block.

[0775] FIG. 19 shows a signal processing circuit for a transmission signal according to one embodiment of the present disclosure. The embodiment of FIG. 19 can be combined with various embodiments of the present disclosure.

[0776] Referring to FIG. 19, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operation / function of FIG. 19 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 18. The hardware elements of FIG. 19 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 18. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 18. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 18, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 18.

[0777] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 19. Here, the codeword is an encoded bit sequence of an information block. The information block may include a transmission block (e.g., UL-SCH transmission block, DL-SCH transmission block). The wireless signal can be transmitted through various physical channels (e.g., terminal-to-base station physical shared channel (e.g., PUSCH), base station-to-terminal physical shared channel (e.g., PDSCH)).

[0778] Specifically, a codeword can be converted into a scrambled bit sequence by a scrambler (1010). The scrambled sequence used for scrambling is generated based on an initialization value, which may include ID information of a wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by an N*M precoding matrix W. Here, N is the number of antenna ports and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on the complex modulation symbols. Additionally, the precoder (1040) can perform precoding without performing transform precoding.

[0779] A resource mapper (1050) can map the modulation symbols of each antenna port to a time-frequency resource. The time-frequency resource may include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. A signal generator (1060) generates a radio signal from the mapped modulation symbols, and the generated radio signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) may include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0780] The signal processing process for a received signal in a wireless device can be configured as the inverse of the signal processing process (1010–1060) of FIG. 19. For example, a wireless device (e.g., 100, 200 in FIG. 18) can receive a wireless signal from the outside through an antenna port / transceiver. The received wireless signal can be converted into a baseband signal through a signal restorer. To this end, the signal restorer may include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a Fast Fourier Transform (FFT) module. Subsequently, the baseband signal can be restored into a codeword through a resource de-mapper process, a postcoding process, a demodulation process, and a de-scrambling process. The codeword can be restored into the original information block through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
