[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".

[0072] In the present disclosure, PUCCH may be replaced with a control channel, a physical control channel, a control channel associated with an uplink, a physical control channel associated with an uplink, a device-to-base station physical control channel, a terminal-to-base station physical control channel, etc. In the present disclosure, a terminal-to-base station physical sharing channel (e.g., PUSCH) may be replaced with a sharing channel, a physical sharing channel, a sharing channel associated with an uplink, a physical sharing channel associated with an uplink, a device-to-base station physical sharing channel, a terminal-to-base station physical sharing channel, etc. For example, UL communication may be replaced with terminal-to-base station communication or device-to-base station communication. 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).

[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).

[0167] For example, if all the instructed data / channels have been received, the terminal can determine whether feedback transmission is necessary, and if feedback transmission is not necessary, the procedure can be terminated.

[0168] For example, if feedback transmission is required, the terminal may transmit feedback (e.g., HARQ-ACK transmission). Afterward, the above procedure may be terminated.

[0169] FIG. 9 is for convenience of explanation only and is not intended to limit the scope of the present disclosure. For example, the terminal-to-base station data / channel transmission and / or the base station-to-terminal data / channel transmission may include NR FR1, FR2, or FR2-2 transmission.

For example, the base station may transmit terminal-to-base station data / channel related information. Subsequently, the base station may transmit base station-to-terminal control information for terminal-to-base station data transmission, or transmit information for terminal-to-base station channel transmission. Subsequently, for example, the base station may receive terminal-to-base station data / channel.

[0172] At this point, for example, the base station may check whether all the designated data / channels have been received, and if not all have been received, it may perform terminal-to-base station data / channel reception (again and / or additionally). If all have been received, the above procedure may be terminated.

[0173] Referring to FIG. 10(b), a flowchart is shown of a base station performing base station-to-terminal data transmission. For example, the base station may transmit base station-to-terminal data / channel related information. Subsequently, the base station may transmit base station-to-terminal control information for receiving base station-to-terminal data, or transmit information for receiving the base station-to-terminal channel. Subsequently, for example, the base station may transmit base station-to-terminal data / channel.

[0174] At this time, for example, the base station can check whether all the designated data / channels have been transmitted, and if not all have been transmitted, it can perform base station-to-terminal data / channel transmission (again and / or additionally).

[0175] For example, if all the instructed data / channel has been transmitted, the base station can determine whether feedback reception is required, and if feedback reception is not required, the procedure can be terminated.

[0176] For example, if feedback reception is required, the base station may receive feedback (e.g., HARQ-ACK transmission). Afterward, the above procedure may be terminated.

[0177] FIG. 10 is for convenience of explanation only and does not limit the scope of the present disclosure. For example, the terminal-to-base station data / channel transmission and / or the base station-to-terminal data / channel transmission may include NR FR1, FR2, or FR2-2 transmission.

The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure.

[0179] Referring to FIG. 11 (a), the base station can transmit terminal-to-base station data / channel related information to the terminal. Subsequently, the base station can transmit base station-to-terminal control information for terminal-to-base station data transmission or information for terminal-to-base station channel transmission to the terminal. Subsequently, the terminal can transmit terminal-to-base station data / channel to the base station.

[0180] Referring to FIG. 11(b), the base station may transmit base station-to-terminal data / channel related information to the terminal. Subsequently, the base station may transmit base station-to-terminal control information for receiving base station-to-terminal data or information for receiving the base station-to-terminal channel to the terminal. Subsequently, the base station may transmit the base station-to-terminal data / channel to the terminal. Subsequently, (if configured to perform a feedback operation,) the terminal may transmit feedback (e.g., HARQ-ACK feedback) to the base station.

[0181] FIG. 11 is for convenience of explanation only and is not intended to limit the scope of the present disclosure. For example, the terminal-to-base station data / channel transmission and / or the base station-to-terminal data / channel transmission may include NR FR1, FR2, or FR2-2 transmission.

[0182] For example, in the present disclosure, transmitting or receiving a low-power wake-up signal time (e.g., LO) may mean transmitting or receiving a low-power wake-up signal (e.g., LP-WUS) during the low-power wake-up signal time (e.g., LO). For example, in the present disclosure, transmitting or receiving a low-power wake-up signal monitoring time (e.g., LMO) may mean transmitting or receiving a low-power wake-up signal (e.g., LP-WUS) during the low-power wake-up signal monitoring time (e.g., LMO). For example, in the present disclosure, transmitting or receiving a paging time (e.g., PO) may mean transmitting or receiving a paging message during the paging time (e.g., PO). For example, in the present disclosure, performing paging may mean receiving a paging message during the paging time (e.g., PO).

It may consist of consecutive resource blocks (RBs) on the frequency axis and may correspond to a single numerology (e.g., subcarrier interval, circular prefix (e.g., CP) length, slot / mini-slot duration).

[0269] COT (Channel occupancy time): Channel occupancy time

[0270] SPS (Semi-persistent scheduling): Semi-permanent scheduling

[0271] QCL (Quasi-Co-Location): Quasi-co-location. A quasi-co-location (e.g., QCL) relationship between two reference signals implies that quasi-co-location (e.g., QCL) parameters obtained from one reference signal, such as Doppler shift, Doppler spread, average delay, delay spread, and spatial Rx parameters, can be applied to another reference signal (or its antenna port(s)). 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≠Y).

[0272] TCI (Transmission Configuration Indication): Transmission configuration indicator. A TCI state includes a pseudo-identical position (e.g., QCL) relationship between one or more base station-to-terminal reference signals (e.g., DL RS) with the decoding reference signal (e.g., DM-RS) port of a base station-to-terminal physical shared channel (e.g., PDSCH), the decoding reference signal (e.g., DM-RS) port of a base station-to-terminal physical control channel (e.g., PDCCH), or the channel state information reference signal (e.g., CSI-RS) port(s) of a channel state information reference signal (e.g., CSI-RS) resource. 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] The present specification describes a method for allocating a low-power wake-up signal occasion (e.g., LO; LP-WUS occasion) to a terminal for transmitting a low-power wake-up signal (e.g., LP-WUS), determining a terminal identifier or terminal group identifier to be used within the low-power wake-up signal occasion (e.g., LO), determining a low-power wake-up signal monitoring occasion (e.g., LMO; LP-WUS monitoring occasion) to be received within the low-power wake-up signal occasion (e.g., LO), and determining a paging occasion (e.g., PO; Paging occasion) to be used for receiving a paging message triggered by the reception after receiving the low-power wake-up signal monitoring occasion (e.g., LMO).

[0277] For example, to reduce power consumption through low-power wake-up signals (e.g., LP-WUS), it may be important to minimize false alarms (situations where a terminal that the base station does not intend to wake up gets up) and to ensure reliable transmission of low-power wake-up signals (e.g., LP-WUS). For example, since the reliability of low-power wake-up signal transmission (e.g., LP-WUS) can vary depending on the length of the terminal identifier or terminal group identifier that must be included in the low-power wake-up signal (e.g., LP-WUS) when the wireless resources used for the low-power wake-up signal (e.g., LP-WUS) are the same, the trade-off relationship between false alarms and the reliability of low-power wake-up signal transmission (e.g., LP-WUS) can be said to lie in the length of the terminal group identifier and the configuration of the low-power wake-up signal opportunity (e.g., LO).

[0278] By applying the method proposed in this specification, low-power wake-up signal opportunities (e.g., LO) and low-power wake-up signal monitoring opportunities (e.g., LMO) can be configured, and the performance of the low-power wake-up signal (e.g., LP-WUS) can be controlled between a false alarm and a low-power wake-up signal. To this end, this specification describes a method for grouping terminals to an appropriate level and configuring them in the transmission of a low-power wake-up signal (e.g., LP-WUS).

[0279] According to one embodiment of the present disclosure, a method for allocating a low-power wake-up signal opportunity (e.g., LO) to a terminal for transmitting and receiving a low-power wake-up signal (e.g., LP-WUS) and a method for indicating an identifier of the terminal or an identifier of a group including the terminal in said low-power wake-up signal opportunity (e.g., LO) are described. For example, a method may be provided in which an identifier of the terminal or an identifier of a group including the terminal is indicated through a low-power wake-up signal (e.g., LP-WUS).

[0280] In the present disclosure, examples are provided based on an NR system to explain the principles of initiation, but the proposed methods are not specifically limited to the transmission and reception forms of NR unless otherwise stated. Furthermore, in the present disclosure, examples are provided based on the characteristics and structure of a discontinuous reception (e.g., DRX) terminal to explain the principles of initiation, but the proposed methods are not specifically limited to the support of a discontinuous reception (e.g., DRX) terminal unless otherwise stated. Therefore, it is obvious that the methods proposed in the present disclosure can be applied to all wireless communication transmission and reception structures and services as long as the principles of initiation are not compromised, even without further explanation.

[0281] 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.

[0282] 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.

[0283] 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).

[0284] 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.

[0285] In various embodiments of the present disclosure, a low-power weather signal occasion (e.g., LP-WUS occasion; LO) may include one or more low-power weather signal (e.g., LP-WUS) monitoring occasions (e.g., monitoring occasion; MO). In other words, one low-power weather signal monitoring occasion (e.g., LP-WUS MO) may be replaced by one low-power weather signal occasion (e.g., LO), or a group of low-power weather signal monitoring occasions (e.g., LP-WUS MO) consisting of one or more low-power weather signal monitoring occasions (e.g., LP-WUS MO) may be replaced by a low-power weather signal occasion (e.g., LO). For example, this may be useful for improving reception performance by associating each low-power weather signal monitoring period (e.g., LP-WUS MO) within a low-power weather signal period (e.g., LO) with a beam or reference signal given or predefined from a base station, and ensuring that the same information is always transmitted in the low-power weather signal monitoring period (e.g., LP-WUS MO) within the low-power weather signal period (e.g., LO), thereby allowing the terminal to select and receive the best low-power weather signal monitoring period (e.g., LP-WUS MO) from the reference signal or by combining the signals received in each low-power weather signal monitoring period (e.g., LP-WUS MO).

[0286] For example, the number of low-power weather signal monitoring periods (e.g., LP-WUS MO) within a low-power weather signal period (e.g., LO) can be directly set through messages such as SIB from the base station, or derived from the number of transmissions per period, such as a reference signal that can be associated with each low-power weather signal monitoring period (e.g., LMO).

[0287] Alternatively, for example, without an explicit association, the terminal may simply assume that each low-power wake-up signal monitoring period (e.g., LP-WUS MO) is a separate transmission. In the series of operations described above, the terminal may assume that the same information is provided through the low-power wake-up signal monitoring period (e.g., LP-WUS MO) within the low-power wake-up signal period (e.g., LO). For example, additionally, the following may be considered in the low-power wake-up signal period (e.g., LO).

[0288] For example, during a given low-power wake-up signal period (e.g., LO), the terminal may perform all monitoring during the monitoring period (e.g., MO) within the low-power wake-up signal period (e.g., LO), or may perform monitoring only during a specific monitoring period (e.g., MO).

[0289] For example, the number of low-power wake-up signal monitoring periods (e.g., LP-WUS MO) within a low-power wake-up signal period (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 wake-up signal monitoring periods (e.g., LP-WUS MO). In such cases, the terminal may consider the following.

[0290] (1) When the number of low-power wake signal monitoring times (e.g., LP-WUS MO) within a low-power wake signal time (e.g., LO) is greater than the number of associated beams or reference signals Y, the nth low-power wake signal monitoring time (e.g., LP-WUS MO) may be assumed to be associated with the ((n-1) mod Y + 1)th beam or transmitted reference signal.

[0291] (2) When the number of low-power wake signal monitoring periods (e.g., LP-WUS MO) X within a low-power wake signal period (e.g., LO) is less than the number of associated beams or reference signals Y,

[0292] 1) The first low-power weather signal monitoring time (e.g., LP-WUS MO) may be associated with the 'number mod Y' of the SFN containing the corresponding low-power weather signal monitoring time (e.g., LP-WUS MO). Additionally, the nth low-power weather signal monitoring time (e.g., LP-WUS MO) may be associated with the ((m+n-1) mod Y + 1)th beam or reference signal if the first low-power weather signal monitoring time (e.g., LP-WUS MO) is associated with the mth beam or reference signal.

[0293] 2) Alternatively, for example, the nth weather signal monitoring time (e.g., LP-WUS MO) may be associated with the set nth beam or reference signal. For example, for this purpose, an ordered index may be set on the beam or reference signal.

[0294] 3) Alternatively, for example, the first weather signal monitoring time (e.g., LP-WUS MO) may be associated with the beam or reference signal closest to the start time of the current low-power weather signal time (e.g., LO). Additionally, the nth weather signal monitoring time (e.g., LP-WUS MO) may be associated with a previously transmitted beam or reference signal of the beam or reference signal associated with the n-1th low-power weather signal time (e.g., LO).

[0295] For example, in the present disclosure, ID can be interchanged with index.

[0296] For example, in the present disclosure, receiving a low-power wake-up signal opportunity (e.g., LO), a low-power wake-up signal monitoring opportunity (e.g., LMO), and / or a paging opportunity (e.g., PO) may be interchangeable with receiving a low-power wake-up signal (e.g., LP-WUS), and / or a paging message in a low-power wake-up signal opportunity (e.g., LO), a low-power wake-up signal monitoring opportunity (e.g., LMO), and / or a paging opportunity (e.g., PO).

[0297] [Proposal #1]

[0298] According to one embodiment of the present disclosure, one or more low-power wake signal opportunities (e.g., LO) may be set for one paging opportunity (e.g., PO). For example, a basic method for determining the location of a low-power wake signal opportunity (e.g., LO) may be as follows.

[0299] 1. For example, the location of a low-power wake signal opportunity (e.g., LO) can be determined as a relative location to a paging opportunity (e.g., PO).

[0300] For example, a low-power wake signal opportunity (e.g., LO) may start earlier by a frame offset TFrame and / or slot / symbol offset Tslot / Tsymbol from the slot / symbol where the paging opportunity (e.g., PO) is located.

[0301] 2. For example, the offset Tslot / Tsymbol can be determined as follows.

[0302] For example, a value defined as terminal capability can be used as an offset. For example, a value indicated or set via a System Information Block (e.g., SIB) can be used as an offset. For example, a predefined length can be used as an offset. For example, an additional offset can be applied depending on whether Early Paging Indication (e.g., PEI) is enabled.

[0303] According to one embodiment of the present disclosure, one or more low-power wake-up signal opportunities (e.g., LO) may be set for a single paging opportunity (e.g., PO). When a single low-power wake-up signal opportunity (e.g., LO) is set for a single paging opportunity (e.g., PO), a single paging opportunity (e.g., PO)-to-low-power wake-up signal opportunity (e.g., LO) offset is used, and when multiple low-power wake-up signal opportunities (e.g., LO) are set for a paging opportunity (e.g., PO), various methods may be applied. For example, the following examples may be provided as methods for setting multiple low-power wake-up signal opportunities (e.g., LO).

[0304] 1. For example, the starting position of each low-power wake signal opportunity (e.g., LO) can be explicitly set.

[0305] For example, similar to paging opportunity (e.g., PO) configuration, the frame / slot where a low-power wake-up signal opportunity (e.g., LO) may occur is additionally determined through its relative position from the paging frame / slot, and the location of the low-power wake-up signal opportunity (e.g., LO) within that frame can be derived through the terminal identifier. For example, in a manner similar to the paging physical base station-to-terminal control channel (e.g., Paging PDCCH), the first symbol location where the (first) low-power wake-up signal opportunity (e.g., LO) occurs within a specific frame / slot can be configured for each low-power wake-up signal opportunity (e.g., LO).

[0306] 2. For example, by using multiple offsets, additional low-power wake signal opportunities (e.g., LO) can be determined based on the relative position relative to the paging opportunity (e.g., PO) position.

[0307] 3. For example, the interval (offset) / number of additional low-power wake-up signal opportunities (e.g., LO) from the first low-power wake-up signal opportunity (e.g., LO) can be set.

[0308] For example, a low-power wake-up signal opportunity (e.g., LO) may occur every X slots / symbols starting from the first low-power wake-up signal opportunity (e.g., LO). For example, X may include the occupancy length of the low-power wake-up signal opportunity (e.g., LO), a predefined value, or a set value.

[0309] For example, the offset can be composed of a positive offset or a negative offset. In the case of a positive offset, an additional low-power wake-up signal opportunity (e.g., LO) occurs at a time after the first low-power wake-up signal opportunity (e.g., LO), and in the case of a negative offset, an additional low-power wake-up signal opportunity (e.g., LO) may occur at a time before the first low-power wake-up signal opportunity (e.g., LO).

[0310] 4. For example, multiplexing of low-power wake signal opportunities (e.g., LO) in the frequency / code / space domain may be possible.

[0311] [Proposal #2]

[0312] The terminal periodically or continuously receives a low-power wake-up signal opportunity (e.g., LO) associated with a configured paging opportunity (e.g., PO), and may selectively receive the low-power wake-up signal opportunity (e.g., LO) using a terminal identifier or a subgroup number. The method for selectively receiving the low-power wake-up signal opportunity (e.g., LO) may be as follows.

[0313] According to one embodiment of the present disclosure, a terminal may receive a low-power wake-up signal opportunity (e.g., LO), a low-power wake-up signal opportunity (e.g., LO) group, or a low-power wake-up signal opportunity (e.g., LO) pattern corresponding to a paging opportunity (e.g., PO) determined to be received, or may receive a low-power wake-up signal opportunity (e.g., LO), a low-power wake-up signal opportunity (e.g., LO) group, or a low-power wake-up signal opportunity (e.g., LO) pattern configured to be received directly.

[0314] According to one embodiment of the present disclosure, a group of terminals receiving the same paging opportunity (e.g., PO) or the same low-power wake signal opportunity (e.g., LO) group / pattern may be further divided into N terminal subgroups (or subgroups). These subgroups may be set separately from or replace up to 8 terminal subgroups for receiving paging early indication (e.g., PEI) according to the prior art.

[0315] According to one embodiment of the present disclosure, a group or pattern of low-power wake signal opportunities (e.g., LO) consists of one or more low-power wake signal opportunities (e.g., LO), and a terminal is allocated one or more low-power wake signal opportunities (e.g., LO) and can receive some or all of the low-power wake signal opportunities (e.g., LO).

[0316] Here, for example, if K low-power weather signal opportunities (e.g., LO) are set in a single low-power weather signal opportunity (e.g., LO) group or pattern, terminals receiving the said low-power weather signal opportunity (e.g., LO) group or pattern together can be further divided into K terminal subgroups to receive them.

[0317] Here, for example, after assigning an index to low-power weather signal opportunities (e.g., LO) within a group or pattern, the terminal can identify the index of the low-power weather signal opportunity (e.g., LO) to be monitored using the index information of the terminal subgroup to which it belongs. Specifically, the terminal can determine the remainder of dividing the index of its subgroup by N as the index of the low-power weather signal opportunity (e.g., LO) to be monitored.

[0318] According to one embodiment of the present disclosure, one or more of the following methods may be performed for terminal identification or subgroup identification:

[0319] 1. A method of receiving some or all of the terminal identifiers (e.g., IMSI, TMSI, C-RNTI) from a single low-power wake signal opportunity (e.g., LO).

[0320] 2. A method for receiving a terminal identifier (e.g., UE ID within the group) within a single low-power wake signal opportunity (e.g., LO).

[0321] 3. A method for receiving information in a single low-power wake signal opportunity (e.g., LO) to identify which subgroup a terminal belongs to among the existing terminal subgroups for receiving paging early indication (e.g., PEI).

[0322] 4. A method for receiving information to identify which subgroup a terminal belongs to among N terminal subgroups, as a combination of a low-power wake-up signal opportunity (e.g., LO) and a payload (or based on a combination of a low-power wake-up signal opportunity (e.g., LO) and a payload).

[0323] According to one embodiment of the present disclosure, a terminal determines a low-power wake signal opportunity (e.g., LO) to receive through an index of the terminal subgroup to which it belongs, and can check whether its subgroup is indicated through the payload content received at the low-power wake signal opportunity (e.g., LO).

[0324] According to one embodiment of the present disclosure, the payload size (R bit) within a low-power wake signal opportunity (e.g., LO), the number of terminal subgroups (N), and / or the number of low-power wake signal opportunities (e.g., LO) (X) can be set through a system information block (e.g., SIB) or upper layer signaling.

[0325] According to one embodiment of the present disclosure, when a terminal receives a low-power wake-up signal opportunity (e.g., LO) indicated by its identifier or subgroup (e.g., when the terminal receives a low-power wake-up signal opportunity (e.g., LO) in a low-power wake-up signal monitoring opportunity (e.g., LMO) within a low-power wake-up signal opportunity (e.g., LO) (e.g., when the terminal receives a low-power wake-up signal (e.g., LP-WUS) message within a low-power wake-up signal opportunity (e.g., LO)), the terminal may receive a paging opportunity (e.g., PO) corresponding to the low-power wake-up signal opportunity (e.g., LO) and stop receiving additional low-power wake-up signal opportunities (e.g., LO).

[0326] To this end, a low-power wake signal (e.g., LP-WUS) message can be interpreted according to the method described below.

[0327] For example, code points transmitted in a low-power wake signal (e.g., LP-WUS) message can be interpreted as information indicating the order of a terminal group.

[0328] Here, for example, the terminal can interpret the received code point in the context of the low-power weather signal opportunity (e.g., LO) group or pattern to which it belongs and derive the actual indicated terminal group.

[0329] Here, for example, this interpretation process may include the following steps.

[0330] (1) The terminal can identify a group or pattern of low-power weather signal opportunities (e.g., LO) that it monitors.

[0331] (2) The terminal can determine the total number (N) of terminal groups receiving the corresponding low-power weather signal opportunity (e.g., LO) group / pattern together and the ID of each group.

[0332] (3) The terminal can interpret the code point received from the low-power wake signal (e.g., LP-WUS) message as sequence information (K).

[0333] (4) The terminal may determine the actual indicated terminal group as the (K mod N) + 1st group, or determine the actual indicated terminal group as the Kth group.

[0334] For example, assuming there are a total of 5 terminal groups receiving a low-power wake-up signal opportunity (e.g., LO) group A together (e.g., group IDs 1, 2, 3, 4, and 5), if a terminal receives code point 7 in a low-power wake-up signal (e.g., LP-WUS) message, then K = 7 and N = 5, so the indicated group could be (7 mod 5) + 1 = 3rd group, and thus, the terminal group corresponding to group ID 3 can be the wake-up target.

[0335] Here, for example, a method for handling discontinuous terminal group IDs may be provided. Here, for example, terminal group IDs assigned to a low-power wake signal opportunity (e.g., LO) group / pattern may not be continuous. In this case, the network may provide a terminal group ID mapping table for the corresponding low-power wake signal opportunity (e.g., LO) group / pattern, or the terminal may derive which terminal group ID will receive the corresponding low-power wake signal opportunity (e.g., LO) group / pattern through the low-power wake signal opportunity (e.g., LO) setting and generate a terminal group ID mapping table. The terminal may use this mapping table to convert the received code point into an actual terminal group ID.

[0336] For example, assuming there are a total of 5 terminal groups receiving low-power wake-up signal opportunities (e.g., LO) group A together (e.g., the associated group IDs may be 2, 5, 8, 11, and 14), if code point 3 is received in a low-power wake-up signal (e.g., LP-WUS) message, K is 3, the mapping table may be [2, 5, 8, 11, 14], and the indicated group may be the 3rd entry in the mapping table, e.g., group ID 8.

[0337] Here, for example, regarding network configuration considerations, the network may need to configure and manage the number of terminal groups and a list of IDs receiving together for each low-power wake signal opportunity (e.g., LO) group / pattern. For example, this information may be provided to the terminals via system information or dedicated RRC signaling.

[0338] For example, when a terminal receives a low-power wake signal (e.g., LP-WUS) message, it can calculate the actual indicated terminal group by combining the received code point with the low-power wake signal opportunity (e.g., LO) group / pattern information that it is monitoring. If the calculated group ID matches its own group ID, the terminal can determine that it is a wake target (e.g., determine that it is a wake target).

[0339] In this way, the terminal can accurately receive the low-power wake-up signal opportunity (e.g., LO) corresponding to its own subgroup among multiple low-power wake-up signal opportunities (e.g., LO) allocated for a single paging opportunity (e.g., PO). Furthermore, according to the above method, false alarms can be reduced and efficient terminal identification can be achieved through various identification methods.

[0340] [Proposal #3]

[0341] According to one embodiment of the present disclosure, a plurality of low-power weather signal monitoring opportunities (e.g., LMO) may be configured within a low-power weather signal opportunity (e.g., LO) to ensure diversity or provide multiple transmission opportunities. The location of the low-power weather signal monitoring opportunities (e.g., LMO) may be determined such that the location of each low-power weather signal monitoring opportunity (e.g., LMO) within the low-power weather signal opportunity (e.g., LO) is individually configured as described in Proposal No. 2, or such that the interval between low-power weather signal monitoring opportunities (e.g., LMO) and the total number are configured. In this case, the time interval used to determine the location and interval may be applied in a reverse direction, taking into account the weather delay time of the terminal, for example, by generating a low-power weather signal monitoring opportunity (e.g., LMO) at an earlier time by a given amount of time.

[0342] According to one embodiment of the present disclosure, a terminal may selectively receive a low-power weather signal monitoring opportunity (e.g., LMO), and to do so, may follow the following procedure.

[0343] 1. Terminal re-indexing procedure

[0344] The terminal can sequentially re-assign terminal identifiers or subgroup numbers capable of receiving low-power weather signal monitoring opportunities (e.g., LMO) within low-power weather signal opportunities (e.g., LO) as 1, 2, 3, ..., NG, low-power weather signal opportunities (e.g., LO).

[0345] The terminal can determine the order of low-power weather signal monitoring opportunities (e.g., LMO) received by each terminal using the remainder obtained by dividing the reordered order by the number of low-power weather signal monitoring opportunities (e.g., LMO) within the low-power weather signal opportunities (e.g., LO) per beam.

[0346] For example, within a low-power wake-up signal opportunity (e.g., LO) received by subgroup numbers 2, 4, 6, and 8, a terminal having subgroup number 6 may be reassigned to number 3. In this case, when there are two low-power wake-up signal monitoring opportunities (e.g., LMO) corresponding to one beam within the low-power wake-up signal opportunity (e.g., LO), since the remainder when number 3 is divided by the number of beams, 2, is 1, the terminal may receive the first low-power wake-up signal monitoring opportunity (e.g., LMO).

[0347] For example, to achieve the same effect, the value obtained by dividing the terminal identifier or subgroup number by the number of low-power wake signal opportunities (e.g., LO) corresponding to one paging opportunity (e.g., PO), or the remainder thereof, may be used. In this case, the reception order of low-power wake signal monitoring opportunities (e.g., LMO) can be determined through the remainder value.

[0348] 2. Indexing of low-power weather signal monitoring opportunities (e.g., LMO)

[0349] The terminal may assign a number to a low-power weather signal monitoring opportunity (e.g., LMO) corresponding to one beam within a low-power weather signal opportunity (e.g., LO), and consider the number of terminal identifiers or subgroups NG receiving the low-power weather signal opportunity (e.g., LO), and the remainder X divided by the low-power weather signal opportunity (e.g., LO).

[0350] For example, terminal identifiers or subgroups receiving the corresponding low-power weather signal opportunity (e.g., LO) may be sorted in descending or ascending order. For example, terminal identifiers or subgroups in the order corresponding to the remainder X of a specific low-power weather signal monitoring opportunity (e.g., LMO) may receive the corresponding low-power weather signal monitoring opportunity (e.g., LMO).

[0351] [Proposal #4]

[0352] According to one embodiment of the present disclosure, a method for repeatedly transmitting a low-power wake signal (e.g., LP-WUS) message may be provided.

[0353] For example, to ensure coverage of a low-power wake-up signal (e.g., LP-WUS) message, a single terminal or a group of terminals may receive multiple low-power wake-up signal monitoring opportunities (e.g., LMO). For example, a low-power wake-up signal (e.g., LP-WUS) message may be transmitted repeatedly. A method for ensuring coverage may be as follows.

[0354] For example, the terminal can receive all low-power weather signal monitoring opportunities (e.g., LMO) within a low-power weather signal opportunity (e.g., LO). For example, the terminal can continuously monitor and attempt to decode all low-power weather signal monitoring opportunities (e.g., LMO) within a low-power weather signal opportunity (e.g., LO).

[0355] For example, the terminal may attempt to receive low-power wake-up signal (e.g., LP-WUS) messages for all low-power wake-up signal monitoring opportunities (e.g., LMO) from the beginning to the end of a low-power wake-up signal opportunity (e.g., LO).

[0356] For example, two or more low-power wake signal monitoring opportunities (e.g., LMOs) may occur for a single beam, and if a terminal receives a low-power wake signal (e.g., LP-WUS) message containing its identifier or subgroup number from at least one of these low-power wake signal monitoring opportunities (e.g., LMOs), the terminal may attempt to receive a paging opportunity (e.g., PO). For example, the terminal monitors the low-power wake signal monitoring opportunities (e.g., LMOs) corresponding to each beam.

[0357] For example, if the terminal successfully decodes a low-power wake signal (e.g., LP-WUS) message containing its identifier or subgroup number at any one low-power wake signal monitoring opportunity (e.g., LMO), it can prepare to receive a corresponding paging opportunity (e.g., PO).

[0358] For example, even when a terminal selectively receives a low-power weather signal monitoring opportunity (e.g., LMO) within a low-power weather signal opportunity (e.g., LO), the terminal can secure coverage by receiving two or more low-power weather signal monitoring opportunities (e.g., LMO).

[0359] For example, the terminal can determine the low-power weather signal monitoring opportunities (e.g., LMOs) to receive based on its identifier or subgroup information. For example, the terminal can monitor at least two of the determined low-power weather signal monitoring opportunities (e.g., LMOs) consecutively or at regular intervals. For example, if any of the low-power weather signal monitoring opportunities (e.g., LMOs) it monitors are successfully decoded, the terminal may attempt to receive the corresponding paging opportunity (e.g., PO).

[0360] To this end, for example, a method of selectively receiving low-power weather signal monitoring opportunities (e.g., LMOs) can be applied by treating every K consecutive low-power weather signal monitoring opportunities (e.g., LMOs) corresponding to a single beam as a single low-power weather signal monitoring opportunity (e.g., LMO).

[0361] Here, for example, the terminal may receive a value K from the network or use a predefined value. Here, for example, K consecutive low-power weather signal monitoring opportunities (e.g., LMO) within a low-power weather signal opportunity (e.g., LO) may be considered as a group. Here, for example, the terminal may determine the group of low-power weather signal monitoring opportunities (e.g., LMO) to receive based on its identifier or subgroup information.

[0362] Here, for example, the terminal can monitor all K consecutive low-power weather signal monitoring opportunities (e.g., LMOs) within a selected group of low-power weather signal monitoring opportunities (e.g., LMOs). Here, for example, the terminal can attempt to receive a corresponding paging opportunity (e.g., PO) if at least one of the K low-power weather signal monitoring opportunities (e.g., LMOs) is successfully decoded.

[0363] As another example, a circular group assignment method can be used for a single beam. For instance, low-power weather signal monitoring opportunities (e.g., LMOs) corresponding to a single beam within a low-power weather signal opportunity (e.g., LO) may be grouped into K groups, and a unique number may be assigned to each group.

[0364] Terminal groups can determine the group of low-power weather signal monitoring opportunities (e.g., LMO) to monitor based on their group IDs. In this case, if the group IDs of the terminal groups monitoring the corresponding low-power weather signal opportunities (e.g., LO) are not consecutive, they may be renumbered to be consecutive, or a value obtained by dividing the group ID by an appropriate number may be used. For example, the group number of low-power weather signal monitoring opportunities (e.g., LMO) to monitor may be Group ID % number of low-power weather signal monitoring opportunities (e.g., LMO) groups. For example, the group number of low-power weather signal monitoring opportunities (e.g., LMO) to monitor may be Group ID mod number of low-power weather signal monitoring opportunities (e.g., LMO) groups. The above method can evenly distribute the load among terminal groups.

[0365] As another example, low-power weather signal monitoring opportunities (e.g., LMOs) corresponding to a single beam within a low-power weather signal opportunity (e.g., LO) may be divided into multiple groups, and the low-power weather signal monitoring opportunities (e.g., LMOs) of each group may be arranged in an interleaved manner. For example, this can be repeated in the order of low-power weather signal monitoring opportunities (e.g., LMOs) of Group A, low-power weather signal monitoring opportunities (e.g., LMOs) of Group B, and low-power weather signal monitoring opportunities (e.g., LMOs) of Group C. For example, a terminal may periodically monitor only the low-power weather signal monitoring opportunities (e.g., LMOs) of the group to which it belongs.

[0366] As another example, a circular interleaving group assignment method (a combination of the two methods above) may be used. Low-power weather signal monitoring opportunities (e.g., LMOs) within low-power weather signal opportunities (e.g., LOs) can be grouped into K groups and arranged in an interleaving manner. For example, groups of low-power weather signal monitoring opportunities (e.g., LMOs) can be assigned based on terminal ID. For example, the assigned group may be Terminal ID % number of low-power weather signal monitoring opportunities (e.g., LMOs). For example, the assigned group may be Terminal ID mod number of low-power weather signal monitoring opportunities (e.g., LMOs).

[0367] For example, each terminal can monitor only the low-power weather signal monitoring opportunities (e.g., LMOs) of the group to which it is assigned. The monitoring period may be the number of low-power weather signal monitoring opportunities (e.g., LMOs) groups * K. Here, this configuration (value of K, number of groups, interleaving pattern) is determined in advance by the network and transmitted to the terminal, and can be maintained for a long period so that it can operate without change even in IDLE mode.

[0368] According to one embodiment of the present disclosure, a method for beam selection and combination in a multi-beam environment may be provided. For example, the signal quality of a low-power weather signal monitoring opportunity (e.g., LMO) corresponding to each beam may be measured. For example, a low-power weather signal monitoring opportunity (e.g., LMO) of the beam with the best signal quality may be selected, or low-power weather signal monitoring opportunity (e.g., LMO) signals received from a plurality of beams may be combined. A low-power weather signal (e.g., LP-WUS) message may be identified by decoding the selected or combined signal.

[0369] Through these methods, the terminal can effectively secure coverage of low-power wake-up signals (e.g., LP-WUS) messages while optimizing power consumption. Through the above methods, reliable reception of low-power wake-up signals (e.g., LP-WUS) can be ensured by flexibly adjusting the reception strategy according to channel conditions and network settings.

[0370] FIG. 12 illustrates a plurality of low-power signal opportunities associated with a single paging opportunity 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.

[0371] Referring to FIG. 12, a resource plane consisting of a time axis and a frequency axis is shown. For example, the resource plane shows a paging opportunity (e.g., PO) and a plurality of low-power signal opportunities (e.g., LO) associated therewith. For example, the plurality of low-power signal opportunities (e.g., LO) may include first low-power signal opportunities (e.g., LO), second low-power signal opportunities (e.g., LO), and third low-power signal opportunities (e.g., LO).

[0372] For example, the first low-power signal opportunities (e.g., LO) may be associated with a first beam. For example, a low-power wake-up signal (e.g., LP-WUS) transmitted from the first low-power signal opportunity (e.g., LO) may be transmitted and / or received using the first beam. For example, a low-power wake-up signal (e.g., LP-WUS) transmitted from at least one low-power signal monitoring opportunity (e.g., LMO) included in the low-power signal opportunity (e.g., LO) may be transmitted and / or received using the first beam.

[0373] For example, the second low-power signal opportunities (e.g., LO) may be associated with a second beam. For example, a low-power wake-up signal (e.g., LP-WUS) transmitted from the second low-power signal opportunity (e.g., LO) may be transmitted and / or received using the second beam. For example, a low-power wake-up signal (e.g., LP-WUS) transmitted from at least one low-power signal monitoring opportunity (e.g., LMO) included in the low-power signal opportunity (e.g., LO) may be transmitted and / or received using the second beam.

[0374] For example, the third low-power signal opportunities (e.g., LO) may be associated with a third beam. For example, a low-power wake-up signal (e.g., LP-WUS) transmitted from the third low-power signal opportunity (e.g., LO) may be transmitted and / or received using the third beam. For example, a low-power wake-up signal (e.g., LP-WUS) transmitted from at least one low-power signal monitoring opportunity (e.g., LMO) included in the low-power signal opportunity (e.g., LO) may be transmitted and / or received using the third beam.

[0375] FIG. 13 illustrates a repetitive transmission performed in low-power signal monitoring opportunities included in a single low-power signal opportunity, 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.

[0376] Referring to FIG. 13, a first low-power wake-up signal opportunity (e.g., LO) appears, which is one of the low-power wake-up signal opportunities (e.g., LO) to transmit a low-power wake-up signal (e.g., LP-WUS) to instruct a terminal receiving a paging message that it should receive the paging message by causing it to wake up at a paging opportunity (e.g., PO).

[0377] The first low-power weather signal opportunity (e.g., LO) may include a plurality of low-power weather signal monitoring opportunities (e.g., LMO). For example, the plurality of low-power weather signal monitoring opportunities (e.g., LMO) may include a first low-power weather signal monitoring opportunity (e.g., LMO) to a fifth low-power weather signal monitoring opportunity (e.g., LMO).

[0378] For example, the same low-power weather signal (e.g., LP-WUS) may be repeatedly transmitted in all of the above-mentioned first low-power weather signal monitoring opportunities (e.g., LMO) to fifth low-power weather signal monitoring opportunities (e.g., LMO). For example, the same beam may be used in the transmission / reception operation of the repeated transmission.

[0379] [Proposal #5]

[0380] According to one embodiment of the present disclosure, when a low-power wake-up signal (e.g., LP-WUS) message is received, a paging opportunity (e.g., PO) may be attempted to be received according to various conditions (e.g., whether a terminal identifier is included, whether a set received / derived terminal subgroup number is included).

[0381] According to one embodiment of the present disclosure, (Alternative 1, reception of a paging opportunity (e.g., PO) associated with a low-power wake-up signal opportunity (e.g., LO)) a terminal may receive a paging opportunity (e.g., PO) directly associated with a low-power wake-up signal opportunity (e.g., LO) in which a low-power wake-up signal (e.g., LP-WUS) is received. Herein, the terminal may operate as follows.

[0382] For example, the terminal can calculate the timing of the low-power wake-up signal opportunity (e.g., LO) from the paging opportunity (e.g., PO) by applying a preset paging opportunity (e.g., PO)-to-low-power wake-up signal opportunity (e.g., LO) offset. For example, the corresponding paging opportunity (e.g., PO) and the low-power wake-up signal opportunity (e.g., LO) can be associated.

[0383] For example, after receiving a low-power wake signal (e.g., LP-WUS) at a low-power wake signal opportunity (e.g., LO), the terminal can activate the main receiver at a calculated timing and monitor the associated paging opportunity (e.g., PO).

[0384] For example, the terminal can receive and process a paging message at an associated paging opportunity (e.g., PO).

[0385] If necessary, the terminal can also monitor additional paging opportunities (e.g., POs) for a certain period of time from the paging opportunity (e.g., PO).

[0386] According to one embodiment of the present disclosure, (Alternative 2, reception of a paging opportunity (e.g., PO) after a certain time after a low-power wake-up signal opportunity (e.g., LO)), the terminal may start receiving from the nearest paging opportunity (e.g., PO) after a certain time has elapsed since receiving a low-power wake-up signal (e.g., LP-WUS). Here, the terminal may operate as follows.

[0387] For example, the terminal can calculate the timing of the nearest paging opportunity (e.g., PO) after the wake-up delay time at each low-power wake-up signal opportunity (e.g., LO). For example, after receiving a low-power wake-up signal (e.g., LP-WUS), the terminal can activate the main receiver at the calculated timing and monitor the corresponding paging opportunity (e.g., PO). For example, the terminal can receive and process paging messages at the corresponding paging opportunity (e.g., PO). For example, depending on the configuration, the terminal can also monitor additional paging opportunities (e.g., PO) for a certain period of time from the first paging opportunity (e.g., PO).

[0388] [Proposal #6]

[0389] According to one embodiment of the present disclosure, a method for considering weather delays may be provided.

[0390] For example, the wake-up delay time is the minimum time it takes for the terminal to activate the main receiver after receiving a low-power wake-up signal (e.g., LP-WUS) message to receive a paging opportunity (e.g., PO), and can be predefined or determined through the terminal's capability report.

[0391] According to one embodiment of the present disclosure, a method for taking into account weather delays may be provided. When taking into account weather delays, the following methods may be applied by considering alternatives 1 and / or 2 of method 5.

[0392] For example, the terminal may selectively apply Alternative 1 or Alternative 2 depending on the wake-up delay. For example, if a paging opportunity (e.g., PO) associated with a set low-power wake-up signal opportunity (e.g., LO) occurs after the terminal's wake-up delay time from the low-power wake-up signal opportunity (e.g., LO), Alternative 1 may be used, otherwise Alternative 2 may be used.

[0393] Alternatively, for example, if Alternative 1 is used, the terminal can expect that the associated paging opportunity (e.g., PO) will always occur after the terminal's wake-up delay time. For example, a paging opportunity (e.g., PO)-to-low power wake-up signal opportunity (e.g., LO) offset set by the base station may ensure that the associated paging opportunity (e.g., PO) will always occur after the terminal's wake-up delay time.

[0394] Alternatively, for example, when Alternative 1 is used, if the terminal periodically receives multiple low-power wake-up signal opportunities (e.g., LO) or multiple low-power wake-up signal monitoring opportunities (e.g., LMO) for one paging opportunity (e.g., PO), it may be expected that the terminal receives only the low-power wake-up signal opportunities (e.g., LO) or low-power wake-up signal monitoring opportunities (e.g., LMO) that occurred prior to the terminal's wake-up delay time from the associated paging opportunity (e.g., PO).

[0395] For example, a low-power wake-up signal opportunity (e.g., LO) drop may be performed. For example, in extreme cases, terminals that take too long to receive a paging opportunity (e.g., PO) after a wake-up delay may stop using the low-power wake-up signal (e.g., LP-WUS) and switch to the existing paging opportunity (e.g., PO) monitoring method. For example, Alternative 1 may be used when the associated paging opportunity (e.g., PO) occurs before the terminal's wake-up delay time, or when the paging opportunity (e.g., PO) determined through Alternative 1 and / or Alternative 2 occurs after a specific threshold time (e.g., threshold time) from the low-power wake-up signal opportunity (e.g., LO).

[0396] [Proposal #7]

[0397] According to one embodiment of the present disclosure, the following method may be considered to effectively determine the timing for monitoring a low-power weather signal (e.g., LP-WUS) (low-power weather signal monitoring opportunity (e.g., LMO)).

[0398] According to one embodiment of the present disclosure, additional information settings may be provided.

[0399] For example, when setting a low-power wake signal opportunity (e.g., LO), unlike a paging opportunity (e.g., PO), there is no external setting to reference (e.g., search space setting), so the following additional information may need to be provided. The following information may be transmitted via the base station's system information block (e.g., SIB) or RRC signaling.

[0400] i) Symbol length of the low-power wake-up signal (e.g., LP-WUS) (including the start symbol). For example, the symbol length of the low-power wake-up signal (e.g., LP-WUS) may be derived based on the low-power wake-up signal (e.g., LP-WUS) transmission structure (OOK-1, OOK-4, M value, etc.) and the payload size. ii) Frequency position of the low-power wake-up signal (e.g., LP-WUS).

[0401] According to one embodiment of the present disclosure, a transmission structure setting for a low-power wake signal (e.g., LP-WUS) may be provided.

[0402] For example, a specific structure for transmitting a low-power wake signal (e.g., LP-WUS) can be configured as follows. For example, a base grid can be created based on OOK-1. For example, the base grid can be created as a slot structure consisting of symbol groups that may contain one OOK-1 information. For example, in OOK-4, this grid can be extended into a nested structure. For example, from symbol groups that may contain one OOK-1 information, multiple symbol groups that may contain one OOK-4 information can be created.

[0403] For example, a location within the slot to be used as a low-power wake signal (e.g., LP-WUS) is set, and the structure can be repeated for each slot.

[0404] Based on this structural information, the terminal can identify accurate time-frequency resources for receiving low-power weather signals (e.g., LP-WUS).

[0405] According to one embodiment of the present disclosure, a long-term OOK transmission processing method may be provided.

[0406] For example, if the OOK transmission exceeds 14 OFDM time symbol lengths due to Manchester encoding or other reasons, the following processing may be performed.

[0407] For example, an extended structure can be formed by repeating a low-power wake signal (e.g., LP-WUS) structure within one slot across N slots. For example, this extended structure can be considered as a single low-power wake signal (e.g., LP-WUS) transmission.

[0408] For example, the terminal can recognize and process N consecutive slots as a single low-power wake signal (e.g., LP-WUS) transmission.

[0409] According to one embodiment of the present disclosure, a repeat reception setting may be provided.

[0410] For example, if a low-power wake signal (e.g., LP-WUS) of a specific number of bits needs to be received multiple times (e.g., if an 8-bit low-power wake signal (e.g., LP-WUS) needs to be received four times), repeated reception can be set by utilizing the structure defined above.

[0411] For example, the terminal can receive low-power wake-up signals (e.g., LP-WUS) as many times as the set number of repetitions and combine them to derive final low-power wake-up signal (e.g., LP-WUS) information.

[0412] According to one embodiment of the present disclosure, structuring of the frequency domain may be provided.

[0413] For example, to efficiently utilize frequency resources for the transmission of low-power wake-up signals (e.g., LP-WUS), the following methods may be considered. For example, the bandwidth of the low-power wake-up signal (e.g., LP-WUS) may be divided and allocated into multiple subbands. For example, by assigning different terminal groups to each subband, it may be possible to enable the simultaneous transmission of low-power wake-up signals (e.g., LP-WUS) to multiple terminal groups.

[0414] For example, the terminal can reduce power consumption by monitoring only the subband allocated to it.

[0415] Through this method, the timing for monitoring low-power wake-up signals (e.g., LP-WUS) can be clearly determined, and various transmission requirements can be flexibly responded to. In addition, efficient resource management and a reduction in reception complexity of the terminal can be achieved through a slot-based structured approach. Based on this structured information, the terminal can monitor and process low-power wake-up signals (e.g., LP-WUS) within accurate time-frequency resources, and efficient wake-up signal reception can be achieved while minimizing power consumption.

[0416] In addition, time / frequency resource allocation methods (e.g., continuous or distributed allocation methods) for low-power wake signal opportunities (e.g., LO) and low-power wake signal monitoring opportunities (e.g., LMO) may be considered, and the system may be designed to enable efficient terminal identification and information transmission by optimizing the payload structure of the low-power wake signal (e.g., LP-WUS) (e.g., group ID, individual ID, additional information fields, etc.).

[0417] For example, as a method for operating low-power wake-up signals (e.g., LP-WUS) in a multi-cell environment, coordination of low-power wake-up signal opportunities (e.g., LO) / low-power wake-up signal monitoring opportunities (e.g., LMO) between cells and processing of low-power wake-up signals (e.g., LP-WUS) during handover may be considered.

[0418] According to various embodiments of the present disclosure, a method for optimizing the setting of low-power wake signal opportunities (e.g., LO) / low-power wake signal monitoring opportunities (e.g., LMO) considering the trade-off between energy efficiency and latency may be introduced, and a method for dynamically adjusting the operation of low-power wake signals (e.g., LP-WUS) according to various traffic patterns and QoS requirements may be considered.

[0419] For example, the Low Power Waiver (e.g., LO) period can be set short for terminals using latency-sensitive services, and long for Internet of Things (e.g., IoT) devices where battery life is critical. This allows for the simultaneous achievement of efficient use of network resources and extended battery life of the terminal.

[0420] 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.

[0421] 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, causes the at least one processor to perform the operation proposed in the present disclosure.

[0422] 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.

[0423] 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.

[0424] 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.

[0425] 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.

[0426] 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.

[0427] In the description of the present disclosure, a low power wake-up signal (LP-WUS) is a low power wake-up signal that allows a terminal to monitor paging at low power while in a state where it is not monitoring paging by default (idle state), and includes an instruction to perform paging after a specific time interval from the time it is received. For example, to maximize the power consumption reduction effect of the low power wake-up signal (e.g., LP-WUS) operation, it may be important to ensure reliable transmission of the low power wake-up signal (e.g., LP-WUS) while minimizing false alarms where a terminal that the base station does not intend to wake up is woken up.

[0428] According to one embodiment of the present disclosure, a many-to-one low-power signal opportunity (e.g., LO) : paging opportunity (e.g., PO) relationship may be defined for a plurality of low-power signal opportunities (e.g., LO) corresponding to a plurality of beams, and a plurality of low-power signal monitoring opportunities (e.g., LMO) within each low-power signal opportunity (e.g., LO) may be considered as a group, and the same low-power wake-up signal (e.g., LP-WUS) may be repeatedly transmitted within the group. Here, the terminal may monitor all groups of the low-power signal monitoring opportunities (e.g., LMO).

[0429] According to one embodiment of the present disclosure, every K consecutive low-power signal monitoring opportunities (e.g., LMOs) corresponding to a single beam are treated as a single low-power signal monitoring opportunity (e.g., LMO), and the low-power signal monitoring opportunity (e.g., LMO) may be selectively received. For example, K consecutive low-power signal monitoring opportunities (e.g., LMOs) within a low-power signal opportunity (e.g., LO) may be considered as a single group. For example, a terminal may determine the group of low-power signal monitoring opportunities (e.g., LMOs) to receive based on its identifier or sub-group information. For example, the terminal may monitor all K consecutive low-power signal monitoring opportunities (e.g., LMOs) within the selected group of low-power signal monitoring opportunities (e.g., LMOs). Subsequently, for example, the terminal may attempt to receive a corresponding paging opportunity (e.g., PO) if at least one of the K low-power signal monitoring opportunities (e.g., LMOs) is successfully decoded.

[0430] According to various embodiments of the present disclosure, coverage of low-power wake signals (e.g., LP-WUS) can be improved by allowing LP-WUS to be repeatedly transmitted in a plurality of low-power signal monitoring opportunities (e.g., LMO), and by associating one paging opportunity (e.g., PO) with a plurality of low-power signal opportunities (e.g., LO), terminal subgroups that need to monitor paging opportunities (e.g., PO) can be identified with higher accuracy, thereby reducing false alarms and flexibly responding to various transmission requirements. In addition, efficient resource management and reduction of reception complexity of terminals can be achieved through a slot-based structured approach, and efficient wake signal reception can be enabled while minimizing power consumption of terminals.

[0503] FIG. 18 shows a signal processing circuit for a transmission signal according to one embodiment of the present disclosure. The embodiment of FIG. 18 can be combined with various embodiments of the present disclosure.

[0504] Referring to FIG. 18, 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. 18 may be performed in the processor (102, 202) and / or transceiver (106, 206) of FIG. 17. The hardware elements of FIG. 18 may be implemented in the processor (102, 202) and / or transceiver (106, 206) of FIG. 17. For example, blocks 1010 through 1060 may be implemented in the processor (102, 202) of FIG. 17. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 17, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 17.

[0505] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 18. 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)).

[0506] 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.

[0507] 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.

[0508] 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. 18. For example, a wireless device (e.g., 100, 200 in FIG. 17) 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.
