Description

Technical Field

[0001] This disclosure generally relates to mobile communications. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology for achieving high-speed packet communication. Many proposals have been put forward for LTE objectives, including those aimed at reducing costs for users and providers, improving quality of service, and expanding and improving coverage and system capacity. 3GPP LTE requires lower cost per bit, increased service availability, flexible use of frequency bands, a simple architecture, open interfaces, and appropriate terminal power consumption as higher-level requirements.

[0003] The International Telecommunication Union (ITU) and 3GPP have begun work to develop requirements and specifications for New Radio (NR) systems. 3GPP has had to identify and develop the technical components needed to successfully standardize the new RATs for both timely meeting urgent market demands and the longer-term requirements outlined by the ITU Radiocommunication Sector (ITU-R) International Mobile Telecommunications (IMT)-2020 process. Furthermore, even in the more distant future, NR should be able to utilize any spectrum band available for wireless communication, at least up to 100 GHz.

[0004] The goal of NR is to provide a single technology framework that addresses all use cases, requirements, and deployment scenarios, including enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). NR will be inherently forward compatible.

[0005] User equipment (UE) can perform measurements based on synchronization signal blocks (SSBs) (or SS / PBCH blocks) sent by the serving cell and / or neighboring cells. UE can also perform measurements based on the SMTC during a time window.

[0006] In subcarrier spacing (SCS) above 480 kHz, the symbol length is smaller than that of SCS below 480 kHz. For example, the operating band of frequency range (FR) 2-2 in NR supports SCS at 480 kHz and 960 kHz. However, traditionally, the small symbol length resulting from SCS above 480 kHz is not considered for performing measurements.

[0007] For example, even in synchronized mode, the serving signal received by the UE and the signals from neighboring cells may deviate from specific symbols. The UE can measure the RSRP based on the SSB using existing technology. In this case, when configuring the SMTC window, symbol lengths of 480kHz or higher according to the SCS are not considered. As a result, there may be issues where the SSB of neighboring cells is not partially included in the SMTC window, which may affect the accuracy of the RSRP measured by the UE. Summary of the Invention

[0008] Therefore, efforts have been made to disclose this specification in order to resolve the aforementioned problems.

[0039] Not limited thereto, the various descriptions, functions, processes, suggestions, methods and / or operation flowcharts disclosed herein can be applied to various fields requiring wireless communication and / or connectivity between devices (e.g., 5G).

[0040] The present disclosure will be described in more detail below with reference to the accompanying drawings. Unless otherwise stated, the same reference numerals in the following drawings and / or description may refer to the same and / or corresponding hardware blocks, software blocks and / or functional blocks.

[0041] Although a user equipment (UE) is illustrated in the accompanying drawings with the aid of examples, the illustrated UE may be referred to as a terminal, mobile device (ME), etc. Furthermore, the UE may be a portable device such as a laptop, mobile phone, PDA, smartphone, multimedia device, or a non-portable device such as a PC, in-vehicle equipment, etc.

[0044] Figure 1 An example of a communication system applying embodiments of the present disclosure is shown.

[0045] Figure 1 The 5G use cases shown are merely illustrative, and the technical features of this disclosure can be applied to... Figure 1 Other 5G use cases not shown.

[0046] The three main demand categories for 5G include (1) Enhanced Mobile Broadband (eMBB), (2) Massive Machine Type Communications (mMTC), and (3) Ultra Reliable Low Latency Communications (URLLC).

[0047] Some use cases may require multiple categories for optimization, while others may focus on only one key performance indicator (KPI). 5G uses a flexible and reliable approach to support such a variety of use cases.

[0048] eMBB goes far beyond basic mobile internet access, encompassing a rich array of two-way work, media, and entertainment applications in the cloud and augmented reality. Data is one of the core drivers of 5G, and for the first time in the 5G era, dedicated voice services may not be available. In 5G, voice is expected to be simply processed as an application using the data connection provided by the communication system. The primary reason for the increase in traffic is the increase in content size and the number of applications requiring high data transmission rates. As more devices connect to the internet, streaming services (audio and video), conversational video, and mobile internet access will be more widely used. Many of these applications require always-on connectivity to push real-time information and alerts to users. Cloud storage and applications are rapidly increasing in mobile communication platforms and can be applied to both work and entertainment. Cloud storage is a specific use case for accelerating the growth of uplink data transmission rates. 5G is also being used for remote work in the cloud. When using haptic interfaces, 5G requires lower end-to-end latency to maintain a good user experience. Entertainment, such as cloud gaming and video streaming, is another core element increasing the demand for mobile broadband capabilities. Entertainment is essential for smartphones and tablets in highly mobile environments, including anywhere, such as trains, vehicles, and airplanes. Other use cases include augmented reality (AR) and information retrieval for entertainment. In this case, AR requires very low latency and instantaneous data volumes.

[0049] Additionally, one of the most anticipated 5G use cases involves the ability to seamlessly connect embedded sensors across all sectors, known as mMTC (modular machine-type communications). The number of potential Internet of Things (IoT) devices is expected to reach 20.4 billion by 2020. Industrial IoT is one of the key categories enabling smart cities, asset tracking, smart utilities, agriculture, and security infrastructure through 5G.

[0050] URLLC includes new services that will transform industries such as autonomous vehicles through remote control of key infrastructure and ultra-reliable / available low-latency links. These levels of reliability and latency are essential for controlling smart grids, automating industry, enabling robotics, and controlling and managing drones.

[0051] 5G is a means of providing streaming speeds rated at hundreds of megabits per second to gigabits per second and can complement fiber-to-the-home (FTTH) and cable-based broadband (or DOCSIS). Delivering TVs with resolutions of 4K or higher (6K, 8K, etc.) as well as virtual reality and augmented reality require such speeds. Virtual reality (VR) and augmented reality (AR) applications include almost immersive sports games. Certain applications may require special network configurations. For example, for VR games, game companies need to integrate their core servers into the network operator's edge network servers to minimize latency.

[0052] Along with many use cases for vehicular mobility communications, automobiles are expected to become a significant new driving force in 5G. For example, passenger entertainment demands high synchronization capacity and mobile broadband with high mobility. This is because future users continue to expect high-quality connectivity regardless of their location and speed. Another use case in the automotive field is AR dashboards. AR dashboards allow drivers to identify objects in the dark beyond what is visible through the windshield and display distances and movement of objects by overlaying information spoken to the driver. In the future, wireless modules will enable communication between vehicles, information exchange between vehicles and supporting infrastructure, and information exchange between vehicles and other connected devices, such as devices that accompany pedestrians. Safety systems will guide alternative routes, allowing drivers to drive more safely and reducing the risk of accidents. The next stage will be remotely controlled or autonomous vehicles. This requires extremely high reliability and very fast communication between different autonomous vehicles and between vehicles and infrastructure. In the future, autonomous vehicles will perform all driving activities, and drivers will only focus on abnormal traffic conditions that vehicles cannot identify. The technological requirements for autonomous vehicles necessitate ultra-low latency and ultra-high reliability, enabling traffic safety to reach levels unattainable by humans.

[0053] Smart cities and smart homes / buildings, as mentioned in the context of a smart society, will be embedded in high-density wireless sensor networks. Distributed networks of smart sensors will identify cost and energy-efficient maintenance needs for cities or homes. Similar configurations can be implemented for individual households. All temperature sensors, window and heating controllers, burglar alarms, and home appliances will be wirelessly connected. Many of these sensors are typically low in data transmission rate, power, and cost. However, certain types of devices may require real-time HD video for monitoring.

[0054] The consumption and distribution of energy, including heat and gas, are allocated at a high level, necessitating automated control of distribution sensor networks. Smart grids use digital information and communication technologies to collect information and connect sensors to each other to act based on the collected data. Since this information may include the behavior of supply companies and consumers, smart grids can improve the distribution of fuels such as electricity through methods that are efficient, reliable, economically feasible, production sustainable, and automated. A smart grid can also be viewed as another sensor network with low latency.

[0055] Mission-critical applications (such as e-health) are one of the use cases for 5G. The health component includes many applications that can benefit from mobile communications. Communication systems can support telemedicine, enabling the delivery of clinical care in remote locations. Telemedicine can help reduce distance barriers and improve access to healthcare services that are not continuously available in remote rural areas. Telemedicine is also used to administer vital treatments and save lives in emergency situations. Mobile communication-based wireless sensor networks can provide remote monitoring and sensors for parameters such as heart rate and blood pressure.

[0056] Wireless and mobile communications are becoming increasingly important in industrial applications. Cabling is costly in terms of installation and maintenance. Therefore, the possibility of replacing cables with reconfigurable wireless links presents an attractive opportunity in many industries. However, to achieve this replacement, it is necessary to establish wireless connections with latency, reliability, and capacity similar to those of cables, and the management of wireless connections needs to be simplified. When connecting to 5G, low latency and a very low error probability become new requirements.

[0057] Logistics and freight tracking is a key use case for mobile communications that utilizes location-based information systems to enable inventory and package tracking anywhere. Logistics and freight use cases typically require low data rates but demand location information with wide coverage and reliability.

[0058] refer to Figure 1 The communication system 1 includes wireless devices 100a to 100f, a base station (BS) 200, and a network 300. Although Figure 1 The 5G network is illustrated as an example of a network for communication system 1, but the embodiments of this disclosure are not limited to 5G systems and can be applied to future communication systems beyond 5G systems.

Holographic devices may include, for example, devices for recording and reproducing stereoscopic information using the interference of light generated when two lasers meet, a phenomenon known as holography.

[0064] Public safety equipment may include, for example, image relay devices or image devices that can be worn on a user's body.

[0065] MTC devices and IoT devices can be, for example, devices that do not require direct human intervention or manipulation. For example, MTC devices and IoT devices can include smart meters, vending machines, thermometers, smart light bulbs, door locks, or various sensors.

For example, a medical device can be a device used for the purpose of diagnosing, treating, alleviating, or correcting an injury or lesion. For example, a medical device can be a device used for the purpose of examining, replacing, or modifying a structure or function. For example, a medical device can be a device used for regulating pregnancy. For example, medical devices can include devices for treatment, devices for operation, devices for (in vitro) diagnostics, hearing aids, or devices for procedures.

[0070] Wireless devices 100a to 100f can be connected to network 300 via BS 200. AI technology can be applied to wireless devices 100a to 100f, and wireless devices 100a to 100f can be connected to AI server 400 via network 300. Network 300 can be configured using 3G networks, 4G (e.g., LTE) networks, 5G (e.g., NR) networks, and super 5G networks. Although wireless devices 100a to 100f can communicate with each other via BS 200 / network 300, wireless devices 100a to 100f can also perform direct communication with each other without going through BS 200 / network 300 (e.g., sidelink communication). For example, vehicles 100b-1 and 100b-2 can perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). IoT devices (e.g., sensors) can perform direct communication with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.

[0071] Wireless communication / connections 150a, 150b, and 150c can be established between wireless devices 100a to 100f and / or between wireless devices 100a to 100f and BS 200 and / or between BS 200.

For example, wireless communication / connections 150a, 150b, and 150c can send / receive signals via various physical channels. Therefore, at least a portion of various configuration information configuration processes, various signal processing processes (e.g., channel coding / decoding, modulation / demodulation, and resource mapping / demapping) and resource allocation processes for transmitting / receiving radio signals can be performed based on various proposals of this disclosure.

[0072] AI refers to the field of studying artificial intelligence or the methodologies that create it, while machine learning refers to the field that defines the various problems that AI addresses and the methodologies for solving these problems. Machine learning is also defined as an algorithm that improves task performance through stable experience with a task.

[0073] A robot is a machine that automatically processes or operates a given task through its own capabilities. Specifically, a robot capable of recognizing its environment and autonomously deciding to perform actions can be called an intelligent robot. Depending on its purpose or field of application, robots can be classified as industrial, medical, domestic, military, etc. Robots can perform various physical operations, such as moving robot joints using actuators or motors.

An autonomous vehicle can be viewed as a robot with autonomous driving capabilities.

[0075] Extended reality is collectively referred to as VR, AR, and MR. VR technology provides real-world objects and backgrounds solely through computer graphics (CG) images. AR technology provides virtual CG images on top of real-world object images. MR technology is a CG technology that combines virtual objects with and integrates them into the real world. MR technology is similar to AR technology in that it presents both real and virtual objects together. However, the difference lies in the fact that in AR technology, virtual objects are used as a supplementary form to real-world objects, while in MR technology, virtual and real objects are treated as equal entities.

[0076] NR supports multiple parameter sets (and / or multiple subcarrier spacings (SCS)) to support a variety of 5G services. For example, a 15kHz SCS enables wide-area coverage in traditional cellular bands; and a 30kHz / 60kHz SCS enables dense urban areas, lower latency, and wider carrier bandwidth. A 60kHz or higher SCS enables bandwidths greater than 24.25GHz to overcome phase noise.

[0077] NR bands can be defined as two frequency ranges, namely FR1 and FR2. The numerical values ​​of the frequency ranges can be changed. For example, the frequency ranges of the two types (FR1 and FR2) can be shown in Table 1 below. For ease of illustration, in the frequency ranges used in NR systems, FR1 can mean "below 6 GHz" and FR2 can mean "above 6 GHz," and can be referred to as millimeter wave (mmW). FR2 can include FR 2-1 and FR 2-2, as shown in the examples in Tables 1 and 2.

[0078] Table 1

[0079]

[0080] As mentioned above, the frequency range of the NR system can be varied. For example, FR1 can include a frequency band from 410MHz to 7125MHz, as shown in Table 2 below. That is, FR1 can include a frequency band of 6GHz (or 5850, 5900, 5925MHz, etc.) or more. For example, the 6GHz (or 5850, 5900, 5925MHz, etc.) or more frequency bands included in FR1 can also include license-free frequency bands. License-free frequency bands can be used for various purposes, such as for vehicle communications (e.g., autonomous driving).

[0110] <SS block in NR>

[0111] In 5G NR, for the information required for a UE to perform initial access, that is, the physical broadcast channel (PBCH) including the master information block (MIB) and synchronization signals (SS) (including PSS and SSS) is defined as an SS block. In addition, multiple SS blocks can be grouped and defined as an SS burst, and multiple SS bursts can be grouped and defined as an SS burst set. It is assumed that each SS block is beamformed in a specific direction, and various SS blocks existing in an SS burst set are designed to support UEs existing in different directions.

[0112] Figure 4 is a diagram illustrating an example of an SS block in NR.

[0113] Reference Figure 4 , to send an SS burst at each predetermined period. Therefore, the UE receives the SS block and performs cell detection and measurement.

[0114] Meanwhile, in 5G NR, beam scanning is performed on the SS. Reference Figure 5 provides its detailed description.

[0115] Figure 5 is a diagram illustrating an example of beam scanning in NR.

[0116] The base station transmits each SS block in an SS burst as time passes while performing beam scanning. In this case, multiple SS blocks in the SS burst set are transmitted to support UEs existing in different directions. In Figure 5In this context, an SS burst set consists of one to six SS blocks, and each SS burst consists of two SS blocks.

[0117] <Neighborhood Search>

[0118] Cell search is the process by which a UE obtains time and frequency synchronization with a cell and detects the cell ID of that cell. NR cell search is based on the primary synchronization signal (PSS) and secondary synchronization signal (SSS) located on the synchronization grid, as well as the PBCH demodulation reference signal (DM-RS).

[0119] The UE's cell search process can be summarized in Table 3.

[0120] [Table 3]

[0121]

[0122] <SSB-based Measurement>

[0123] An example of SSB-based measurement is described.

[0124] For intra-frequency measurements, if the UE is not instructed to report SSB-based RRM measurement results with an associated SSB index (reportQuantityRsIndexesormaxNrofRSIndexesToReport is not configured), the UE should be able to T identify_intra_without_index The UE must either identify a new detectable intra-frequency cell or be instructed to synchronize neighboring cells with the serving cell (enabling derivedSSB-IndexFromCell). Otherwise, the UE should be able to... identify_intra_with_index The UE should be able to identify new detectable intra-frequency cells. identify_intra_without_index Identify new detectable intra-frequency SS blocks in the already detected cell. Assume that deriveSSB-IndexFromCell is always enabled for FR1 TDD and FR2.

[0125] Here, `deriveSSB-IndexFromCell` indicates whether the UE can derive the index of the SS block transmitted by the neighboring cell using the serving cell timing. If this field is set to true, the UE assumes that the system frame number (SFN) and frame boundary are aligned across cells on the serving frequency. The UE can receive system information including `deriveSSB-IndexFromCell` from the serving cell. For example, the UE can receive SIB (System Information Block) 2 including `deriveSSB-IndexFromCell` from the serving cell.

[0126] T identify_intra_without_index =(T PSS / SSS_sync_intra +T SSB_measurement_period_intra )ms

[0127] T identify_intra_with_index =(T PSS / SSS_sync_intra +T SSB_measurement_period_intra +T SSB_time_index_intra )ms

[0128] T PSS / SSS_sync_intra : The time period used in PSS / SSS detection

[0129] T SSB_time_index_intra_CCA : This is the time period used to obtain the index of the measured SSB.

[0130] T SSB_measurement_period_intra_CCA : Equal to the measurement cycle of SSB-based measurements

[0131] The following figures are provided to illustrate specific examples of this specification. Because the names of specific devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0132] Figure 6 An example of a time period used to detect synchronization signals is shown.

[0133] For example, Figure 6 An example of a time period used for PSS / SSS detection in FR 2 is shown.

[0134] Note 1: If different SMTC periodicity is configured for different cells, the required SMTC period is the period used by the identified cell.

[0135] Figure 6 The parameters shown can be defined as follows:

[0136] M pss / sss_sync_w / o_gaps For UEs that support FR2 power class 1 or 5, M pss / sss_sync_w / o_gaps =40. For UEs supporting power level 2, M pss / sss_sync_w / o_gaps =24. For UEs supporting FR2 power class 3, M pss / sss_sync_w / o_gaps =24. For UEs supporting FR2 power level 4, M pss / sss_sync_w / o_gaps =24.

[0137] CSSF intra It is a carrier-specific scaling factor and is determined.

[0138] When the in-band SMTC partially overlaps with the measurement gap, Kp = 1 / (1 - (SMTC period / MGRP)), where the SMTC period < MGRP. When the in-band SMTC partially overlaps with the measurement length (ML) of the network-controlled small gap (NCSG), Kp = 1 / (1 - (SMTC period / VIRP)), where the SMTC period < visible interruption repetition period (VIRP). For the calculation of K p If the higher-layer signaling of smtc2 is configured, for the cells indicated by the pci-List parameter in smtc2, the SMTC periodicity corresponds to the value of the higher-layer parameter smtc2; for other cells, the SMTC periodicity corresponds to the value of the higher-layer parameter smtc1.

[0139] Here, smtc1 can refer to the primary measurement timing configuration defined in 3GPP TS 38.331 V16.6.0. Here, smtc2 can refer to the auxiliary measurement timing configuration for the SS corresponding to this MeasObjectNR with the PCI listed in the pci-List defined in 3GPP TS 38.331 V16.6.0. For these SSs, the periodicity is indicated by the periodicity in smtc2, and the timing offset is equal to the offset indicated in periodicityAndOffset modulo the periodicity. The periodicity in smtc2 can only be set to a value strictly less than the periodicity indicated by periodicityAndOffset in smtc1 (e.g., if periodicityAndOffset indicates sf10, the periodicity can only be set to sf5; if periodicityAndOffset indicates sf5, smtc2 cannot be configured). The UE can receive the information element (IE) MeasObjectNR from the serving cell. MeasObjectNR can include smtc1 and / or smtc2. The IE MeasObjectNR specifies the information applicable to in-band / inter-band measurements of SS / PBCH blocks and / or in-band / inter-band measurements of CSI-RS.

[0140] smtc1 or smtc2 can include the duration and periodicityAndOffset. The duration can refer to the duration of the measurement window in which the SS / PBCH block is to be received. The duration is given in subframe numbers. periodicityAndOffset can refer to the periodicity and offset of the measurement window in which the SS / PBCH block is to be received. Here, the measurement window can be referred to as the SMTC window in this disclosure.

[0159] <Disclosure of this specification>

[0160] In subcarrier spacing (SCS) above 480 kHz, the symbol length is smaller than that of SCS below 480 kHz. For example, the operating band of frequency range (FR) 2-2 in NR supports SCS at 480 kHz and 960 kHz. However, traditionally, the small symbol length resulting from SCS above 480 kHz is not considered for performing measurements.

[0161] For example, even in synchronized mode, the serving signal received by the UE and the signals from neighboring cells may deviate from specific symbols. The UE can measure RSRP based on SSB using existing techniques. In this case, when the SMTC window is configured, symbol lengths of 480kHz or higher according to the SCS are not considered. Therefore, there may be issues where the SSB of neighboring cells is not partially included in the SMTC window, potentially affecting the accuracy of the RSRP measured by the UE.

[0162] This can be applied to the NR FR2-2 band, supporting SCS based on 480 / 960kHz. With SCS at 480kHz or higher, the symbol duration is short. Therefore, reception timing errors may occur when the terminal receives signals from the serving cell and neighboring cells. Considering the data transmission / reception limitations caused by reception timing errors, SMTC settings need to be discussed for performing SSB-based measurements.

[0163] As mentioned above, the frequency range of NR FR 2-2 is defined by Table 2. FR2-2 supports 120kHz, 480kHz, and 960kHz SCS (subcarrier spacing). (The following text is incomplete and requires further context.) Figure 9 This is an example of the new SSB pattern for the 480 and 960 kHz SCS used in NR FR2-2. For the 120 kHz SCS, the same SSB pattern used in FR2-1 is employed.

[0164] The following figures are provided to illustrate specific examples of this specification. Because the names of particular devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0165] Figure 9 An example of an SSB diagram is shown.

[0166] Figure 9 An example of an SSB pattern for a 480kHz / 960kHz SCS is shown. Figure 9 As shown, an SSB can be sent within 4 consecutive symbols.

[0167] The UE can perform measurements based on the SSB. The SSB can be transmitted from the serving cell and / or neighboring cells.

[0168] To measure SS-RSRP, SS-RSRQ, and SS-SINR based on neighbor SSBs, the UE can use the serving cell timing if deriveSSB-IndexFromCell is enabled. Here, neighbor SSB can refer to an SSB sent by a neighboring cell.

[0169] Here, `deriveSSB-IndexFromCell` indicates whether the UE can utilize the serving cell timing to derive the index of the SS block transmitted by the neighboring cell. If this field is set to true, the UE assumes SFN and frame boundary alignment across cells on the serving frequency. The UE can receive system information including `deriveSSB-IndexFromCell` from the serving cell. For example, the UE can receive SIB (System Information Block) 2 including `deriveSSB-IndexFromCell` from the serving cell.

[0170] Typically, for FR2 (FR2-1), deriveSSB-IndxFromCell is always enabled, so the UE uses the serving cell timing to measure neighboring cell SSBs. For example, the UE can measure the SSBs transmitted by neighboring cells using the serving cell timing because deriveSSB-IndxFromCell is always enabled. The tolerance for frame boundary alignment across cells on the same frequency carrier is min(2 SSB symbols, 1 PDSCH symbol). That is, the tolerance can be the minimum between 2 SSB symbols and 1 PDSCH symbol. In the case of TDD deployment, the cell phase synchronization accuracy is 3 microseconds. Here, cell phase synchronization accuracy can refer to the maximum absolute deviation of frame start timing between any pair of cells on the same frequency with overlapping coverage areas. However, because the symbol duration decreases with increasing SCS, the value of min(2 SSB symbols, 1 PDSCH symbol) is less than the cell phase synchronization accuracy for 480 / 960kHz SCS. Therefore, deriveSSB-IndexFromCell cannot always be enabled for the FR2-2 frequency range. Therefore, deriveSSB-IndexFromCell should depend on the network configuration.

[0171] Therefore, deriveSSB-IndexFromCell can be enabled or disabled based on the network configuration used for FR 2-2. In other words, the serving cell can configure deriveSSB-IndexFromCell to be enabled or disabled.

[0172] In the following text, examples of scheduling constraints and SSB-based measurements can be described for two cases: 1) deriveSSB-IndexFromCell enabled, and 2) deriveSSB-IndexFromCell not enabled.

[0173] 1. Has deriveSSB-IndexFromCell (when deriveSSB-IndexFromCell is enabled)

[0174] If deriveSSB-IndexFromCell is enabled for high SCS via the network, it may mean that the cross-cell frame boundary alignment offset will be less than min (2 SSB symbols, 1 PDSCH symbol). In other words, when deriveSSB-IndexFromCell is enabled, the difference between the frame boundaries of the serving cell and neighboring cells is less than min (2 SSB symbols, 1 PDSCH symbol). Therefore, if deriveSSB-IndexFromCell is enabled for high SCS via the network, the UE can assume that the cross-cell frame boundary alignment offset should be less than min (2 SSB symbols, 1 PDSCH symbol).

[0175] The following figures are provided to illustrate specific examples of this specification. Because the names of particular devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0176] Figure 10 The illustration shows an example of tolerance for SCS at 480kHz.

[0177] Figure 10 An example of minimum tolerance (2 SSB symbols, 1 PDSCH symbol) is shown. Figure 10 As shown, the frame boundary of a serving cell with SCS480kHz is the boundary between symbol 13 of the first time slot and symbol 0 of the second time slot.

[0178] like Figure 10 As shown, the frame boundaries of neighboring cells 1 to 4 are all aligned within min (2 SSB symbols, 1 PDSCH symbol) from the boundary of the serving cell.

[0179] In this scenario, scheduling constraints can be introduced by placing two data symbols before and / or after each consecutive SSB symbol configured to be measured, regardless of the beam switching time within the SMTC window duration. This is because, unlike the conventional FR2-1 SSB pattern, ... Figure 9 As shown, a new SSB pattern is defined in the time slots used for high SCS.

[0180] The following figures are provided to illustrate specific examples of this specification. Because the names of particular devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0181] Figure 11a The illustration shows a first example of timing offset considering the tolerance for SCS at 480 kHz. Figure 11b The illustration shows a second example of timing offset considering SCS tolerance for 480kHz.

[0182] Figure 11a and Figure 11b An example of timing offset between SCS configurations considering a minimum (2 SSB symbols, 1 PDSCH symbol) tolerance is shown.

[0183] The serving cell's SCS can be 480kHz, and the neighboring cell's SSB's SCS can be 960kHz, such as... Figure 11a As shown in the diagram. In this case, when the beam switching time is defined as 200ns, scheduling restrictions can be applied to symbol #13 before the start of the SMTC window of the serving cell. Here, a beam switching time of 200ns can be defined to measure the SSB for the 960kHz SCS by considering a data symbol tolerance of 1. With a beam switching time of 50ns, no scheduling restrictions are needed for symbol #13. This is due to the relationship between the beam switching time and the CP length. For example, the CP length for the 480kHz SCS can be 146 nanoseconds, and the CP length for the 960kHz SCS can be 73 nanoseconds. When the beam switching time is 200 nanoseconds, the beam switching time is greater than the CP length for both the 480kHz and 960kHz SCS. Therefore, scheduling restrictions apply in this case. On the other hand, when the beam switching time is 50ns, since 50ns is less than the CP length for both the 480kHz and 960kHz SCS, it does not affect transmission or reception on the symbol, and therefore no scheduling restrictions are needed.

[0184] The SCS of both the serving cell and the neighboring cell can be 480kHz, such as... Figure 11b As shown in the diagram. In this case, when the beam switching time is defined as 200ns, scheduling constraints can be applied to symbol #0 after the end of the serving cell's SMTC window.

[0185] In short, if deriveSSB-IndexFromCell is enabled, and for high SCS, the beam switching time is greater than the CP length, then scheduling constraints should apply to the last symbol before the start of the SMTC window and the first symbol after the end of the SMTC window. For example, the CP length for 480kHz SCS could be 146 nanoseconds, and the CP length for 960kHz SCS could be 73 nanoseconds.

[0186] Scheduling limitations are described below with examples.

[0187] The following scheduling restrictions apply to SS-RSRP or SS-SINR measurements on cells within the FR2-2 frequency band:

[0188] If `deriveSSB_IndexFromCell` is enabled for FR2-2, the UE is not expected to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, the two data symbols preceding each consecutive SSB symbol to be measured, and the two data symbols following each consecutive SSB symbol to be measured within the SMTC window duration. For example, the UE is not expected to send data to and receive data from the serving cell on the SSB symbol to be measured. If SMTC2 higher-layer signaling is configured, SMTC periodically follows SMTC2; otherwise, SMTC periodically follows SMTC1. If the beam switching time is greater than the CP length for FR2-2 SCS, the UE is not expected to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the last symbol before the start of the SMTC window and the first symbol after the end of the SMTC window.

[0189] The following scheduling restrictions apply to SS-RSRQ measurements on cells within the FR2-2 frequency band:

[0190] If the signaling `deriveSSB_IndexFromCell` is enabled for FR2-2, the UE is not expected to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, the RSSI measurement symbol, and the two data symbols before / after each consecutive SSB to be measured / within the duration of the SMTC window. If the higher-layer signaling for SMTC2 is configured, the SMTC periodically follows SMTC2; otherwise, the SMTC periodically follows SMTC1. If the beam switching time is greater than the CP length for the FR2-2 SCS, the UE is not expected to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the last symbol before the start of the SMTC window and the first symbol after the end of the SMTC window.

[0191] 2. Does not have deriveSSB-IndexFromCell (when deriveSSB-IndexFromCell is not enabled)

[0192] If deriveSSB-IndexFromCell is not enabled over the network for high SCS, the UE must detect the frame boundaries of neighboring cells. The offset for cross-cell frame boundary alignment will be less than the cell phase synchronization accuracy, which is 3 microseconds. Therefore, scheduling constraints can be introduced by three data symbols before and after each consecutive SSB symbol, which are configured to be measured regardless of beam switching time within the SMTC window duration.

[0193] The following figures are provided to illustrate specific examples of this specification. Because the names of particular devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0194] Figure 12a The illustration shows a first example of timing offset considering cell phase synchronization accuracy. Figure 12b The illustration shows a second example of timing offset considering cell phase synchronization accuracy.

[0195] Figure 12a and Figure 12b An example of timing offset between SCS configurations that takes into account cell phase synchronization accuracy is shown.

[0196] exist Figure 12a and Figure 12b In this context, the serving cell's SCS can be 480kHz and the neighboring cell's SSB's SCS can be 480kHz / 960kHz, with the SSB symbol potentially partially outside the SMTC window duration. Therefore, SSB measurement accuracy may be affected. To address this issue, the following methods can be considered:

[0197] Method 1) An additional margin, such as a time slot, half a time slot, or a symbol, can be added before and / or after the STMC window duration to keep all SSB symbols within the STMC window duration. For example, an extension of the SMTC window duration can be applied. For example, the serving cell can configure the additional margin and send information related to the additional margin to the UE.

[0198] Method 1-1) introduces 0.5 ms and 1.5 ms SMTC window durations as an example. For instance, additional 0.5 ms and 1.5 ms SMTC window durations can be added to the traditional SMTC window duration.

[0199] Method 2) Add a negative offset option (e.g., slot or symbol level) to SMTC periodicityAndOffset to cover all SSB symbols. For example, the start of the SMTC window can be configured to begin earlier than the negative offset. For example, when the negative offset option is added, the start of the SMTC window can be moved to cover... Figure 12a The #2 symbol is for a neighboring cell with a frequency of 960 kHz. Here, SMTCperiodicityAndOffset can refer to the periodicity and offset of the measurement window in which SS / PBCH blocks are to be received. For example, the serving cell can configure a negative offset and send information related to the negative offset to the UE.

[0200] Method 3) allows the UE to measure the SSB of neighboring cells in advance for a specific duration before the start of the SMTC window and / or for a specific duration after the end of the SMTC window. Depending on the timing of the neighboring cells, the specific duration can be a time slot, half a time slot, or a symbol. Additional scheduling constraints may be required for the specific duration. The UE can configure the specific duration by taking into account the timing of the neighboring cells.

[0201] Scheduling limitations are described below with examples.

[0202] Due to SS-RSRP or SS-SINR measurements on cells within the FR2-2 frequency band, the following scheduling restrictions apply:

[0203] If the signaling `deriveSSB_IndexFromCell` is not enabled for FR2-2, the UE is not expected to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, the three data symbols preceding each consecutive SSB symbol to be measured, and the three data symbols following each consecutive SSB symbol to be measured within the SMTC window duration. If the higher-layer signaling for SMTC2 is configured, the SMTC periodically follows SMTC2; otherwise, the SMTC periodically follows SMTC1.

[0204] The following scheduling restrictions apply to SS-RSRQ measurements on cells within the FR2-2 frequency band:

[0205] If the signaling `deriveSSB_IndexFromCell` is not enabled for FR2-2, the UE is not expected to send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, the RSSI measurement symbol, and the 3 data symbols / RSSI symbols before each consecutive SSB symbol to be measured and the 3 data symbols / RSSI symbols after each consecutive SSB symbol to be measured within the SMTC window duration. If the higher-layer signaling of SMTC2 is configured, SMTC periodically follows SMTC2; otherwise, SMTC periodically follows SMTC1.

[0206] The measurement gap configuration can also be modified for the three methods described above.

[0207] For example, for method 1), the same additional margin window can be added before and after measuring the gap length. For method 1-1), 1 ms and 2 ms MG lengths can be introduced. For example, the additional 1 ms MG length and / or 2 ms MG length can be added to the conventional MG length.

[0208] For example, for method 2), the same negative offset option for gapOffset can be defined to cover the SMTC window.

[0209] For method 3), the UE is allowed to retune the RF carrier frequency before the start of the SMTC window and / or after the end of the SMTC window to measure the SSB of neighboring cells. A specific duration of MG timing advance should be applied (including the RF retuning time of 0.25 ms), and / or the MG should be maintained by the UE for a specific duration after the MG (including the RF retuning time of 0.25 ms).

[0210] The above method can be applied regardless of deriveSSB-IndexFromCell, because additional timing differences may be introduced due to the difference in signal propagation between the serving cell and neighboring cells.

[0211] On the UE side, the UE can measure and report RSRP / RSRQ / SINR using the configured SMTC / MG based on the methods described above. The network (e.g., the serving cell) can then manage UE mobility such as handover based on the reported measurements.

[0212] The following figures are provided to illustrate specific examples of this specification. Because the names of particular devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0213] Figure 13The illustration shows an example of the operation of a UE performing measurements according to this disclosure.

[0214] The SCS of the serving cell or neighboring cells can be equal to or greater than 480 kHz.

[0215] The SMTC configuration is determined based on the SCS of the serving cell or neighboring cells being equal to or greater than 480kHz. The SMTC configuration is then configured for RSRP / RSRQ / SINR measurements of neighboring cells.

[0216] The UE can determine whether neighboring cells are known.

[0217] If neighboring cells are unknown, the UE performs cell identification. For example, the UE can perform SSS / PSS detection and PBCH detection. After performing cell identification, the UE can perform measurements based on the SSB of neighboring cells.

[0218] If neighboring cells are known, the UE can perform measurements based on the neighboring cells' SSBs.

[0219] When the UE performs measurements based on the SSB of a neighboring cell, as described in the examples in this disclosure, the following can be applied, for example: depending on the timing between the serving cell and the neighboring cell, the UE is allowed to measure the SSB of the neighboring cell in advance for a specific duration (e.g., a symbol) before the start of the SMTC window and / or including a specific duration (a symbol) after the end of the SMTC window.

[0220] The following figures are provided to illustrate specific examples of this specification. Because the names of particular devices or signals / messages / fields described in the figures are provided by way of example, the technical features of this specification are not limited to the specific names used in the following figures.

[0221] Figure 14 The illustration shows an example of the operation of a UE and serving cell according to this disclosure.

[0222] Figure 14 This illustrates an example of operation by the UE and the serving cell. The UE and / or the serving cell can perform the operations described in this specification, even if they are not in [the specified location]. Figure 14 As shown in the diagram. Here, the network can be a gNB, base station, serving cell, etc.

[0223] The UE and the network (e.g., the serving cell) can perform the operations explained above through various examples.

[0224] In step S1401, the serving cell may send measurement configuration-related information to the UE. The UE may receive measurement configuration-related information from the network (e.g., base station, serving cell).

[0225] In step S1402, the UE may perform a measurement. The UE may perform the measurement based on examples of this disclosure. For example, the UE may perform a measurement of SSBs transmitted from neighboring cells and / or serving cells, depending on whether the UE can utilize the timing of the serving cell to derive the index of the SS blocks transmitted by the neighboring cells. For example, the UE may perform a measurement of neighboring cells based on whether deriveSSB-IndexFromCell is enabled.

[0226] For example, when deriveSSB-IndexFromCell is enabled, the following example applies. The UE can assume that the offset for cross-cell frame boundary alignment should be less than min (2 SSB symbols, 1 PDSCH symbol). Due to SS-RSRP or SS-SINR measurements on intra-frequency cells in FR2-2, the following scheduling constraints apply. For FR2-2, it is not expected that the UE will transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, on the two data symbols before each consecutive SSB symbol to be measured, and on the two data symbols after each consecutive SSB symbol to be measured within the SMTC window duration. If the beam switching time is greater than the CP length for FR2-2 SCS, it is not expected that the UE will transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the last symbol before the start of the SMTC window and on the first symbol after the end of the SMTC window. The following scheduling restrictions apply to SS-RSRQ measurements on FR2-2 intra-frequency cells. For FR2-2, it is not expected that the UE will send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, the RSSI measurement symbol, and the two data symbols / RSSI symbols before each consecutive SSB to be measured and the two data symbols / RSSI symbols after each consecutive SSB to be measured within the duration of the SMTC window. If the beam switching time is greater than the CP length for the FR2-2 SCS, it is not expected that the UE will send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the last symbol before the start of the SMTC window and the first symbol after the end of the SMTC window.

[0227] For example, when deriveSSB-IndexFromCell is not enabled, the following examples apply. Method 1) Additional margins, such as a slot, half a slot, or symbol, can be added before and / or after the STMC window duration to keep all SSB symbols within the STMC window duration. For example, an extension of the SMTC window duration can be applied. Method 1-1) introduces SMTC window durations of 0.5 ms and 1.5 ms as an example. Method 2) Add a negative offset option (e.g., slot or symbol level) to SMTCperiodicityAndOffset to cover all SSB symbols. For example, the start of the SMTC window can be configured to begin earlier than the negative offset. For example, when the negative offset option is added, the start of the SMTC window can be moved to cover... Figure 12a The #2 symbol of a neighboring cell with 960kHz is included. Method 3) allows the UE to measure the SSB of the neighboring cell in advance for a specific duration before the start of the SMTC window and / or for a specific duration after the end of the SMTC window. Depending on the timing of the neighboring cell, the specific duration can be a time slot, half a time slot, or a symbol. Additional scheduling restrictions may be required for the specific duration. The specific duration can be configured by the serving cell by taking into account the timing of the neighboring cell. The following scheduling restrictions apply for SS-RSRP or SS-SINR measurements on in-frequency cells of FR2-2. For FR2-2, it is not expected that the UE will send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, and on the 3 symbols before each consecutive SSB symbol to be measured and on the 3 data symbols after each consecutive SSB symbol to be measured within the SMTC window duration. The following scheduling restrictions apply to SS-RSRQ measurements on in-frequency cells of FR2-2. For FR2-2, it is not expected that the UE will send PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on the SSB symbol to be measured, the RSSI measurement symbol, and the 3 data symbols / RSSI symbols before each consecutive SSB to be measured and the 3 data symbols / RSSI symbols after each consecutive SSB to be measured within the duration of the SMTC window.

[0228] In step S1403, the UE may send a measurement report to the serving cell. For example, after the UE performs a measurement, it may send the measurement report to the base station. The network (e.g., the serving cell) can then manage UE mobility, such as handover, based on the reported measurements.

[0229] In the following, apparatus (e.g., UE) in a wireless communication system according to some embodiments of the present disclosure will be described.

[0230] For example, the device may include at least one processor, at least one transceiver, and at least one memory.
