Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communications, and more particularly, to a method performed by a user equipment, UE, and a user equipment in a communication system. BACKGROUND

[0002] Considering the development of wireless communication generation after generation, these technologies have been mainly developed targeting human-oriented services such as voice calls, multimedia services, and data services. As the 5th-generation (5G) communication system is commercialized, it is expected that the number of connected devices will grow exponentially. These will be increasingly connected to communication networks. Examples of the Internet of Things can include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machinery, and factory equipment. Mobile devices are expected to evolve in various forms such as augmented reality glasses, virtual reality headsets, and hologram devices. There are ongoing efforts to develop an improved 6G communication system in order to provide various services by connecting hundreds of billions of devices and things in the 6th-generation (6G) era.

[0003] The 6G communication system, which is expected to be commercialized around 2030, will have all the indicators significantly improved compared to the existing 5G communication system. Its peak rate will reach at least 50 Gbit / s, the user experience rate will reach at least 300 Mbit / s, the air interface latency will be less than 1 ms, and the air interface reliability will reach 10 -5 In addition to the above communication basic indicators, the 6G communication system will have a perception capability, an AI-related capability, and better security, interoperability, and sustainability.

[0004] In order for the 6G communication system to achieve the above indicators, more advanced air interface technologies and network technologies need to be developed. The evolution of extreme MIMO (extreme Multiple Input Multiple Output) is currently being considered, including the use of a super large-scale antenna array, the development and evolution of a distributed antenna system, and the design of a MIMO air interface algorithm with the assistance of AI. This technology can achieve higher spectral efficiency, greater coverage, and accurate positioning, perception functions, etc. In addition, technologies that help improve high-frequency coverage, including lenses and antennas based on metamaterials, new antenna architectures, and RIS (reconfigurable intelligence surface), also need better evolution and development.

[0005] To meet the new functionalities added to 6G communication systems, it is necessary to develop new technologies in areas such as network energy saving, air interface security, and network security, while also studying the feasibility of converged technologies such as integrated communication and sensing.

[0006] In addition, to improve spectrum efficiency and overall network performance, the following technologies have been developed for 6G communication systems: full-duplex technology to enable uplink and downlink transmissions to use the same frequency resources simultaneously; network technologies that utilize satellites, high-altitude platform stations (HAPS), etc., in a comprehensive manner; improved network architecture to support mobile base stations, etc., and to enable network operation optimization and automation; dynamic spectrum sharing technology based on spectrum usage prediction and conflict avoidance; the use of artificial intelligence (AI) in wireless communication to improve overall network operation by utilizing AI from the design phase of 6G development and internalizing end-to-end AI support functions; and next-generation distributed computing technologies that overcome the computing power limitations of user equipment (UE) by leveraging ultra-high-performance communication and computing resources (such as mobile edge computing (MEC), cloud, etc.) achievable on the network. Furthermore, efforts are continuing to enhance connectivity between devices, optimize networks, promote the software-defined networking of network entities, and increase the openness of wireless communications by designing new protocols to be used in 6G communication systems, developing mechanisms for achieving hardware-based secure environments and secure data use, and developing technologies for maintaining privacy.

[0007] The research and development of 6G communication systems, encompassing hyper-connectivity for both person-to-machine (P2M) and machine-to-machine (M2M) interactions, is expected to deliver the next wave of hyper-connected experiences. Specifically, services such as truly immersive extended reality (XR), high-fidelity mobile holograms, and digital replicas are anticipated to be provided through 6G communication systems. Furthermore, services such as remote surgery for enhanced security and reliability, industrial automation, and emergency response will be available via 6G communication systems, enabling the technology to be applied across a wide range of sectors including industry, healthcare, automotive, and home appliances.

Figure 2 The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 gNBs 101 and 103 can have the same or similar configurations. However, gNBs come in a variety of configurations, and Figure 2 This disclosure is not intended to limit the scope to any particular implementation of gNB.

[0157] like Figure 2 As shown, gNB 102 includes multiple antennas 200a 200n, multiple radio frequency (RF) transceivers 201a 201n, transmit (TX) processing circuitry 203, and receive (RX) processing circuitry 204. gNB 102 also includes a controller / processor 205, a memory 206, and a backhaul or network interface 207.

[0158] RF transceivers 201a and 201n receive incoming RF signals, such as signals transmitted by the UE in network 100, from antennas 200a and 200n. RF transceivers 201a and 201n down-convert the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signal is sent to RX processing circuitry 204, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 204 sends the processed baseband signal to controller / processor 205 for further processing.

[0159] TX processing circuit 203 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 205. TX processing circuit 203 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 201a and 201n receive the processed baseband or IF signal from TX processing circuit 203 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 201a and 201n.

[0160] The controller / processor 205 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 205 may control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 201a 201n, the RX processing circuit 204, and the TX processing circuit 203, according to known principles. The controller / processor 205 may also support additional functions, such as more advanced wireless communication capabilities.

[0161] For example, the controller / processor 205 can support beamforming or directional routing operations, where outgoing signals from multiple antennas 200a 200n are weighted differently to effectively redirect the outgoing signals in the desired direction. Any of a variety of other functions can be supported in the gNB 102 via the controller / processor 205.

[0162] The controller / processor 205 is also capable of executing programs and other processes located in the memory 206, such as the operating system (OS). The controller / processor 205 can move data into or out of the memory 206 as needed by the executing process.

[0163] The controller / processor 205 is also connected to a backhaul or network interface 207. The backhaul or network interface 207 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. Interface 207 can support communication via any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G, LTE, or LTE A), interface 207 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, interface 207 can allow the gNB 102 to communicate via a wired or wireless local area network or via a wired or wireless connection to a larger network (such as the Internet). Interface 207 includes any suitable structure that supports communication via wired or wireless connections such as Ethernet or RF transceivers.

[0164] Memory 206 is connected to controller / processor 205. A portion of memory 206 may include random access memory (RAM), and another portion of memory 206 may include flash memory or other read-only memory (ROM).

[0165] although Figure 2 An example of gNB 102 is shown, but it is possible to see more. Figure 2 Various changes can be made. For example, gNB 102 can include any number of Figure 2 Each component is shown in the diagram. As a specific example, an access point may include multiple interfaces 207, and the controller / processor 205 may support routing functionality to route data between different network addresses. As another specific example, although shown as a single instance of TX processing circuitry 203 and a single instance of RX processing circuitry 204, gNB102 may include multiple instances of each (such as one per RF transceiver). For example, Figure 2 The various components can be combined, further subdivided, or omitted, and additional components can be added as needed.

[0166] Figure 3 An example user equipment according to an embodiment of the present disclosure is shown. Figure 3 The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111, 115, 117, and 119 can have the same or similar configurations. However, UEs appear in multiple configurations, and Figure 3 This disclosure is not intended to limit the scope to any particular implementation of the UE.

[0167] like Figure 3 As shown, UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a TX processing circuit 303, a microphone 304, and a receive (RX) processing circuit 305. UE 116 also includes a speaker 306, a controller or processor 307, an input / output (I / O) interface (IF) 308, an input device 309, a touchscreen display 310, and memory 311. Memory 311 includes an OS 312 and one or more applications 313.

[0168] RF transceiver 302 receives incoming RF signals transmitted by gNB of network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 305, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 305 sends the processed baseband signals to speaker 306 (e.g., for voice data) or processor 307 for further processing (e.g., for web browsing data).

[0169] TX processing circuit 303 receives analog or digital voice data from microphone 304 or other outgoing baseband data (such as web data, email, or interactive video game data) from processor 307. TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 302 receives the processed baseband or IF signal from TX processing circuit 303 and up-converts the baseband or IF signal into an RF signal transmitted via antenna 301.

[0170] Processor 307 may include one or more processors or other processing devices and executes OS 312 stored in memory 311 to control the overall operation of UE 116. For example, processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals by RF transceiver 302, RX processing circuitry 305, and TX processing circuitry 303 according to known principles. In some embodiments, processor 307 includes at least one microprocessor or microcontroller.

[0171] Processor 307 is also capable of executing other processes and programs located in memory 311, such as processes for CSI reporting on the uplink channel. Processor 307 can move data into or out of memory 311 as needed for executing processes. In some embodiments, processor 307 is configured to execute application 313 based on OS 312 or in response to signals received from gNB or operator. Processor 307 is also coupled to I / O interface 308, which provides UE 116 with the ability to connect to other devices such as laptops and laptops. I / O interface 308 is the communication path between these accessories and processor 307.

[0172] The processor 307 is also connected to the touchscreen display 310. The user of the UE 116 can use the touchscreen display 310 to input data into the UE 116. The touchscreen display 310 can be a liquid crystal display, a light-emitting diode display, or other display capable of rendering text and / or at least limited graphics such as those from a website.

[0173] Memory 311 is connected to processor 307. A portion of memory 311 may include RAM, and another portion of memory 311 may include flash memory or other ROM.

[0174] although Figure 3 An example of UE 116 is shown, but it is possible to modify it. Figure 3 Make various changes. For example, Figure 3 The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Moreover, although... Figure 3 The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0175] Several aspects of this disclosure will now be described by way of example with reference to the accompanying drawings. It should be understood that the use of names in this disclosure is merely exemplary, and other names may be used. For example, for ease of description, names relating to Network Energy Saving (NES) or adaptive / adaptive (meaning adaptable, or adaptive, or adaptable) transmission information or parameters may include NES or r19, or use NES or r19 as a prefix, suffix, superscript, or subscript, to distinguish them from the names of corresponding parameters or information in conventional networks or transmissions. For example, SMTC NES This indicates a measurement timing configuration used for network power saving or adaptive / adaptive SSB transmission, which corresponds to and is distinct from SSB-based measurement timing configurations (SMTC) in traditional networks. Such naming examples are not intended to limit information or parameter names to the described names, but can be replaced with other appropriate names. For example, appropriate names can also use r20, ps, etc. as prefixes or suffixes, or the example prefixes or suffixes can be included in other places in the name, or other names without similar prefixes or suffixes can be used. All of these are within the scope of this disclosure.

[0176] The purpose of NES is to reduce total network energy consumption. total Meanwhile, for NR, downlink (DL) transmission power / energy is defined from the energy aspect of each RE (resource element).

[0177] In the time domain, NES (Network Element System) involves the base station transmitting / receiving common signals / channels, including at least one of the following: Synchronization Signal / Physical Broadcast Channel Block (SSB), SIB1, other SI (Other System Information), paging, and Physical Random Access Channel (PRACH), to ensure that the UE can access the correct cell through signal or channel detection and perform subsequent normal network-UE (NW<->UE) interaction and communication. For these three high-energy-consuming signals / channels—SSB, paging, and PRACH—how the NW can reduce its active time ratio while maintaining necessary transmissions, such as how the NW can achieve deeper and longer sleep opportunities under low load conditions, has become a research focus. Adaptive transmission of common signals / channels is an effective solution. One aspect of this disclosure relates to adaptive transmission of SSB and paging in the time domain.

[0178] Common signal / channel adaptable / adaptive transmission

[0179] One of the benefits of adaptable / adaptable common signal / channel transmission is that, under low load conditions, it allows NW to sleep more deeply and for longer periods between transmission occasions or after consecutive transmission occasions.

[0180] Paging performs adaptive / adaptive transmission in the time domain

[0181] Without increasing paging latency, at least one of the following methods may be included: 1. Modifying the PF distribution within a DRX cycle, such as using a PF with a centralized / compressed / limited distribution; 2. Increasing the number of POs in the PF.

[0182] UE Behavior and RRM Requirements

[0183] Possible scenarios

[0184] Not all cells support NES. Cells can be divided into NES cells that support NES and ordinary cells that do not support NES. User equipment served by ordinary cells or user equipment that does not support NES can be referred to as legacy UE in this disclosure.

[0185] The behavior of a traditional UE in a normal cell conforms to all the requirements defined in standard 38.133. For idle mode (or RRC idle mode)...

[0186] A. In idle mode, the UE needs to perform cell search, cell selection, cell re-selection, and paging reception. The defined RRM (Radio Resource Management) requirements mainly include the measurement and evaluation of the serving cell, the measurement of intra-frequency NR cells, the measurement of inter-frequency NR cells, and the maximum interruption during paging reception.

[0187] Connection mode

[0188] In intra-cell connectivity mode, the measurements considered may include L1-measurement, which includes Layer 1 Reference Signal Received Power (L1-RSRP), Layer 1 Signal to Noise and Interference Ratio (L1-SINR), Radio Link Monitoring (RLM), Beam Failure Detection (BFD), and Candidate Beam Detection (CBD). The reference signal for the measurement may include SSB and CSI-RS. In the description of this patent, SSB is used as a non-limiting example for the purpose of description.

[0189] 1. For idle mode

[0190] 1. The above method does not introduce two measurement timing configurations for the serving cell measurement and evaluation requirements in idle mode; that is, it does not introduce a second per-cell timing configuration. However, when an NES cell can serve not only Type 1 UEs (e.g., NES-enabled UEs) but also traditional UEs, the NW can transmit reference signals (SSBs) or paging (e.g., enable / disable based on service load, or trigger based on L1 signaling) based on both configurations, and both configurations can be active. NES-enabled UEs can understand the newly defined SSB configuration and also understand the traditional configuration. In this case, when both configurations are received simultaneously, the NES UE will perform new processing behaviors different from those of traditional UEs, thus having a new impact on the measurement and evaluation requirements. Therefore, the measurement and evaluation requirements defined in the above method need to be improved by considering the two SSB configurations.

[0191] 2. The measurement and evaluation requirements for the serving cell and neighbor cell measurement requirements defined in the above method need to be improved and enhanced. SSB adaptive / adaptive transmission will introduce new periods (potentially defining SSB periods greater than 160ms or less than 5ms) and new resource activation methods. In this case, the SMTC period T applicable to traditional SSB configurations will be affected. SMTC SSB-adaptable / adaptive resources are no longer applicable or can no longer be included, and all SMTC-based decisions may also become inapplicable. Simultaneously, SSB-adaptive / adaptive transmission introduces new SSB transmission modes, such as changing the location of SSBs in SSB bursts to make them more compact. In this case, if evaluation is performed using SSBs based on the new mode, the DRX period as the granularity of evaluation time is no longer suitable; a smaller unit associated with the new SSB mode can be redefined as the granularity. Furthermore, the introduction of new period or new SSB mode configurations may introduce new conflict relationships, and the relaxation factor may also have a new definition. Moreover, because triggering SSB transmission adaptation / adaptation may occur within a period of time when both adapted / adaptive SSBs and traditional SSBs are used to average RSRP / RSRQ measurement results, the existing definition of measurement result averaging is no longer applicable; otherwise, it may cause performance losses in cell selection or subsequent reselection.

[0192] 3. Meanwhile, according to the measurement mechanism involved in the above method, the NW configures a fixed pattern of SSB / SSB burst sets within one SSB cycle / measurement time window. Therefore, the UE needs to be woken up multiple times to perform measurements (e.g., Figure 7As shown in the diagram, and in extreme cases, inter-frequency measurement opportunities may be lost (e.g., no inter-frequency measurement is performed when DRX = 320ms and SMTC = 160ms). According to the SSB / SSB burst set design in NES, if the UE can perform measurements according to the densely periodically distributed SSBs, it may have the opportunity to enter a longer sleep state to save power, and it can also provide additional opportunities for inter-frequency measurements.

[0193] 4. The maximum interruption requirement during paging reception may be affected. Consider defining the maximum interruption requirement based on a new measurement timing.

[0194] 2. Regarding connection mode

[0195] 1. In the above method, the delay requirements defined for L3 and L1 measurements in the intra-cell scenario are no longer applicable.

[0196] This disclosure relates to aspects related to the measurement of NES-enabled UEs in both idle and connected modes within an NES cell.

[0197] In a single-carrier NES cell scenario, a NES-enabled UE, in any RRC state (RRC idle or connected), can perform RRM measurements on up to two types of received reference signals according to a proportional rule, based on information sent by the network related to the second reference signal and / or the first reference signal (e.g., adaptive / adaptive activation / enable indication), under the condition that both the new NES-specific SSB and the traditional SSB are simultaneously active / transmitting. For example, the two types of reference signals may include a first reference signal and a second reference signal, with different configurations. In one implementation, the first reference signal can be a traditional SSB, and the second reference signal can be an adaptive / adaptive SSB. For instance, relative to the configuration of the first reference signal, the configuration of the second reference signal may involve different SSB modes, different SSB periods, or the period of the second reference signal may be a subset of the optional configuration periods of the first reference signal, etc. In other words, the transmission of the SSB as the second reference signal is adaptive / adaptive relative to the transmission of the traditional SSB.

[0198] In one implementation, in idle mode, the UE completes the measurement and evaluation of the serving cell within the maximum first time.

[0199] Secondary cell RRM measurements include at least one of the following: measurements of the serving cell in idle mode, intra-frequency neighbor cell measurements, or inter-frequency neighbor cell measurements; at least one of L3-RSRP measurements, L1-RSRP measurements, and CBD measurements in connected mode.

[0200] ● The reference signal can be SSB. ● The network's adaptability / adaptability activation / enablement indication can be L1 signaling DCI, L2 signaling MAC-CE, or higher-layer indications. Higher-layer indications may include SIB configuration updates.

[0201] ■ L1 signaling may include a new DCI format with an S-RNTI or a new RNTI, or add indication information related to the adaptability / adaptability of the reference signal configuration to an existing DCI. The existing DCI may be at least one of DCI format 2_7, DCI format 1_0, or paging DCI;

[0202] ■ L2 signaling: Indication information related to the adaptability / adaptability of the reference signal configuration can be found in the original...

[0203] Add new content to MAC-CE, or use a newly defined MAC-CE instruction.

[0204] ●The first instance is related to at least one of the following factors:

[0205] ■ DRX period, the RF chain start time period used to perform intra-frequency neighbor cell measurements, for adaptability.

[0206] / Adaptive measurement configuration timing cycle T for SSB SMTC_NES And the measurement configuration timing period T for traditional SSB SMTC ;

[0207] ■ The relationship between paging occasion (PO) and SMTC time-domain configuration: PO can correspond to two configurations: NES-specific paging (or secondary paging) and / or traditional paging. ● Proportional rules, including at least one of the following:

[0208] 1. The UE determines the DRX period length, T SMTC_NES / Adaptable / Adaptive SSB cycle (second SSB cycle) to determine new serving cell and / or neighboring cell measurement and evaluation granularity;

[0209] 2. The UE determines the period length (T) based on the DRX cycle length. SMTC_NES And determine the new scaling factor M1 based on the PO time slot location, and determine the conditions for using M1 to relax the NES measurement cycle in the scenario.

[0210] 3. The UE fuses the measurement results (e.g., SS-RSRP / SS-RSRQ results) calculated separately based on adaptive / adaptive SSB and traditional SSB according to a proportional relationship, and uses at least X5 measurement values ​​to perform measurement averaging / measuring filtering on the SS-RSRP / RSRQ of the serving cell. The UE's current cell quality is determined from the N strongest SSB blocks (adaptive / adaptive SSB + traditional SSB blocks) that meet the quality threshold, resulting in stable and reliable cell-level measurement values. The interval between these X5 measurement values ​​can be related to the DRX period length, T. SMTC_NES and T SMTC It is related to at least one of them.

[0211] ■ X5 can be used with the newly defined SSB mode, which is related to the SSB signal strength, at least 2.

[0212] 4. UE based on DRX cycle, second SSB cycle / T SMTC_NES At least one of the following is used to determine a new relaxation factor M2: the PO time slot location and the RF processing time; and to determine the conditions for using M2 to relax the intra-frequency and inter-frequency NES neighbor cell measurement periods.

[0213] (In addition, if the UE can perform measurements according to a specific new SSB mode, such as more dense SSB, it can also enable the UE to perform concentrated measurements without having to wake up multiple times, thus providing a new power-saving mode on the UE side.)

[0214] ■ For cell reselection, the NES UE uses the DRX period and the second SSB period / T. SMTC_NES At least one of M2 determines a new detection, measurement, and evaluation cycle.

[0215] ● Additionally, in connection mode, for a known Transmission Configuration Indicator (TCI) state, a TCI state switching command is received within a second time period, wherein the second time period is related to T... SMTC_NES Related.

[0216] UEs that can obtain and understand new SSB / PRACH / paging configuration information sent by the NW in an NES cell are called Type 1 UEs, such as NES-enabled UEs. UEs that do not understand the new configuration information are called traditional UEs. This can be divided into the following scenarios: Scenario 1: NES-only cells and ordinary cells have overlapping coverage. In this scenario, such as... Figure 8 As shown, the coverage areas of NES cells and regular cells overlap, but the coverage area of ​​NES cell 2 is smaller than that of regular cell 1. Scenario 2: NES cell, which can serve both NES-enabled UEs and traditional UEs.

[0217] In this scenario, an NES cell can serve both NES UEs and traditional UEs, meaning the network can be configured with two SSB configurations: an additional configuration and a default configuration, and both configurations can be active or effective simultaneously. Scenario 3: An NES-only cell can only serve UEs that support NES.

[0218] In this scenario, such as Figure 9 As shown, NW can use MIB to broadcast a cellBarred indication to prohibit traditional UEs from camping in this NES cell.

[0219] The following sections will describe in detail the solutions disclosed herein for scenarios where NES UEs can receive new NES SSB adaptive / adaptive configurations and default configurations, including scenarios 1 and 2. Furthermore, scenario 3 will only have NES-compliant SSB adaptive / adaptive configurations. Since neither scenario will affect the performance or requirements of traditional UEs, unless otherwise specified, the UEs mentioned in this disclosure refer to UEs capable of NES, receiving adaptive / adaptive SSBs, or adaptive / adaptive paging, such as NES-supporting UEs.

[0220] 2.2.2 Measurement in Idle Mode

[0221] When NW has two SSB configurations, how and when does NW trigger / activate / enable SSB adaptability / adaptability?

[0222] Because there is no L2 signaling, such as MAC-CE, in idle mode, NW can be triggered by at least one of the following methods:

[0223] 1. Option 1: DCI

[0224] 2. Option 2: SIB1

[0225] Using DCI, SSB adaptable / adaptive configurations can be triggered or activated by at least one of the following:

[0226] DCI format 1_0 with a new RNTI or a new DCI format X_X with an S-RNTI or a new RNTI, for example, the new DCI field can be used to directly indicate the adaptable / adaptable SSB mode or period; DCI format 2_7 with a 1-bit SSB adaptable / adaptable activation configuration indication; paging DCI with a 1-bit SSB adaptable / adaptable activation configuration indication.

[0227] Using SIB1, in idle mode, the UE decodes relevant SSB parameters from SIB1 and can also use SIB1 updates to inform the UE of these SSB parameter updates. SIB1 updates are indicated by short messages in DCI format 1_0. It can be broadcast as a group common signaling to multiple UEs every default paging cycle *{2,4,8,16}. The update cycle via SIB1 is slow. The SIB1 scheme is suitable for stationary users or users with low-speed movement.

[0228] ● New UE behaviors based on DCI indications, such as Figure 11 As shown.

[0229] like Figure 11 As shown, the UE finds a suitable cell and camps normally. At time t1, the UE receives a DCI indication for SSB adaptability / adaptability. The UE expects to receive an adaptable / adaptable SSB (which could be an SSB with a changed cycle or a changed mode) after a certain period of time.

[0230] Option 1: Since the NW already has multiple SSB configurations, one of which is an SSB adaptability / adaptability configuration that is only understood by the NES user, the DCI can have a 1-bit SSB adaptability / adaptability activation indication. The UE obtains the SSB adaptability / adaptability activation indication by decoding the DCI, and thus can obtain the corresponding new SSB configuration from SIB1.

[0231] Option 2: The DCI content is directly indicated to one of the pre-configured SSB candidates. For example, a few bits (e.g., one or more bits) are used to indicate the changed SSB mode.

[0232] The UE receives the adaptive / adaptive SSB at time t2 after T1+T3. At this time, T = T1+T3, including DCI processing time and time margin.

[0233] Because the UE in idle mode only wakes up to listen for paging during the DRX on duration, and the network also configures a timer for the DRX on duration (e.g., DRX activity time), up to a maximum of 1200ms. Based on the DRX activity time, T... SMTC_NEC The relationship between T1 and T3 can be categorized into the following cases:

[0234] Scenario 1: Event time >> T1+T3+T SMTC_NESThe UE is configured with a very long active time, much longer than T1+T3. Therefore, the UE can receive adaptable / adaptive SSBs during the ON duration. If the newly configured SSB / SSB burst set pattern is a dense or compact configuration and the SSB period is very short, i.e., T SMTC_NES is also very short, the UE can receive adaptable / adaptive SSBs and perform measurements during the ON duration without having to wake up additionally during the DRX off duration for measurements, thus achieving power saving.

[0235] Case 2: T1+T3 < DRX active time < T SMTC_NES ,

[0236] This case includes two possibilities: The DRX active time itself is very short and can only cover the time of T1+T3. Another possibility is that the DRX timer expires after T1+T3 for the UE. At this time, the UE can decode DCI to obtain SSB adaptable / adaptive information during the DRX active time and / or during the DRXInactivityTimer active period. However, since the DRX timer operation period cannot include T SMTC_NES , the UE can only wake up again during the DRX off duration (e.g., the UE is in the sleep mode) for additional SSB measurements. However, according to the adaptable / adaptive SSB configuration, the UE does not need to wake up multiple times in multiple DRX cycles for measurements. For example, the UE can perform intensive measurements concentratedly within 1 DRX cycle. After that, there is no need to measure the SSB again and it enters the sleep mode until it receives the SSB adaptable / adaptive deactivation indication at the next DRX active time and then performs necessary measurements based on the traditional SSB (or non-adaptable / adaptive SSB, default SSB, etc.) using T SMTC for measurements. This can also achieve the purpose of power saving.

[0237] Case 3: DRX active time < T1+T3

[0238] In this case, since the UE does not know when the NW sends DCI, it needs to keep listening for paging DCI related to adaptable / adaptive transmission or adaptable / adaptive DCI to monitor the DCI indicating SSB adaptable / adaptive in the ON duration until it receives DCI at time t1. At this time, the UE needs to perform SSB measurements during an additional DRX off duration.

[0239] Case 1 and Case 2 are as Figure 12 shown. As Figure 12 shown, the default SSB period is, for example, 80 ms.

[0240] In scenario 1, the adaptable / adaptive SSB corresponds to an SSB with a more densely distributed pattern (e.g., a time-domain compressed or squeezed SSB). During DRX activity, the UE can receive the DCI for SSB adaptability / adaptability, and after a certain period of time, it begins receiving adaptable / adaptive SSBs and is able to complete the reception of adaptable / adaptive SSBs (e.g., the measurement timing configuration period T for adaptable / adaptive SSBs). SMTC_NES During the DRX activity period, the UE then enters sleep mode. Afterward, except for listening for paging information, the UE does not need to wake up in sleep mode to perform measurements, thus saving power.

[0241] In scenario 2, the adaptable / adaptive SSB has a different period configuration compared to the default SSB, with a shorter transmission period, for example, the second SSB period = 20ms. During DRX activity time, the UE can receive the DCI for SSB adaptability / adaptability and begin receiving adaptable / adaptive SSBs after a certain period, but cannot complete the reception of adaptable / adaptive SSBs during DRX activity time (e.g., the measurement timing configuration period T for adaptable / adaptive SSBs). SMTC_NES (Activity time exceeding DRX overlaps with the DRX off duration). In Case 2, the UE needs to wake from sleep mode to perform measurements during the off duration of the DRX cycle in which it receives the DCI for SSB adaptability / adaptability, but it does not need to receive adaptability / adaptability SSBs in subsequent DRX cycles to perform measurements until it receives the DCI for deactivating SSB adaptability / adaptability. In Case 2, the UE only needs to wake from sleep mode once to perform measurements, and then enters sleep mode again except for monitoring paging, thus saving power.

[0242] ● During cell selection or cell reselection, when both configurations corresponding to the new NES-specific SSB and the traditional SSB are simultaneously active or valid, and / or when a traditional PO exists, network energy-saving behaviors may include at least one of the following:

[0243] A. The effect of PO in measurement, such as the relationship between PO and T. SMTC_NES The impact involves at least one of the following:

[0244] 1. Determination of the relaxation factor M1 for service cell measurement and assessment;

[0245] 2. Determination of the relaxation factor M2 for intra-frequency and inter-frequency NES neighbor cell measurements;

[0246] 3. Maximum interruption during paging reception;

[0247] B. Averaging algorithm for measurement results when different SSBs (default SSB and adaptive / adaptive SSB) cause resource overlap.

[0248] The following is a detailed description.

[0249] √ Relaxation factor M1 determination for serving cell measurement and evaluation .

[0250] Combining the adaptive / adaptive / traditional paging configuration and the adaptive / adaptive / traditional SSB configuration, there are four possible scenarios:

[0251] Scenario 1: Paging is a traditional paging configuration. When using DRX, the UE only needs to monitor one PO per DRX cycle. However, SSB adaptability / adaptability indication / Short message is included in the paging DCI. An example diagram for this scenario is shown below. Figure 13 As shown.

[0252] For serving cell idle mode measurements, when the UE starts the measurement (e.g., Figure 13 When the NES UE receives a DCI indication for SSB adaptability / adaptability, it preferentially selects the adaptable / adaptable SSB configuration. At this time, for new SSB modes or periods, a new timing window period SMTC_NES, also known as the SMTC_NES period or T, can be introduced. SMTC_NES The relaxation factor can be set in at least one of the following two ways:

[0253] Method 1: SSB can be adapted / configured as dense periodic or compact SSB / SSB burst set mode, with SMTC_NES period equal to PO TDM and greater than a first threshold, which is related to the RF chain start time, for example, but not limited to 20ms. When the DRX period is less than or equal to 0.64s, a relaxation factor greater than 1 can be introduced, for example, M1=2, to obtain synchronization and perform measurements, for example...

[0254] If SMTC_NES period (T) SMTC_NES If M1 > 20ms and DRX period ≤ 0.64 seconds, then M1 = 2; otherwise, M1 = 1.

[0255] Method 2: SSB can be adapted / configured as dense periodic or compact SSB / SSB burst set mode, and T SMTC_NES If the time is less than 20ms, do not perform relaxation, for example, set the relaxation factor to 1 and M1 = 1.

[0256] When the UE receives an SSB adaptive / adaptive DCI indication during a measurement gap (e.g., adaptive / adaptive start point 2), since the UE has already performed measurements and obtained synchronization using the previous sparse SSB, there is no need to use the adaptive / adaptive SSB for synchronization again. However, if the SMTC period T of the adaptive / adaptive SSB is... SMTC_NES It is greater than a second threshold, which is related to, for example, the RF chain open time, such as T. SMTC_NES If the time is greater than 20ms, the NES UE will still need to wake up to perform measurements and synchronization before the next PO monitoring reception.

[0257] Scenario 2: The paging is configured as traditional, and the SSB is also configured as default or traditional.

[0258] At this time, the demand for NES UE will not be affected.

[0259] Scenario 3: The paging is an adaptive / adaptive paging configuration, and the SSB is a traditional or default configuration.

[0260] As mentioned earlier, possible adaptive / adaptive configurations for paging could involve modifying the PF distribution within a DRX cycle, such as centralizing / compressing / limiting the PF distribution or increasing the number of POs in the PF. Figure 14 As shown. The possible scenarios include the following:

[0261] Because the SSB configuration remains unchanged, the following two problems will occur:

[0262] 1. Adaptive / adaptive paging and configured SSBs overlap. In extreme cases, the SSB synchronized before paging overlaps with the adaptive / adaptive paging in the time domain. Since paging is not discarded, the measurement requirements can be relaxed to avoid affecting the existing measurement opportunities and performance. A relaxation factor M3 = 1.5 can be introduced.

[0263] 2. When two paging configurations are configured in an NES cell (e.g., including the default paging configuration and the adaptive / adaptive paging configuration), a maximum of two configurations can be active. The NES UE can still read the traditional paging configuration information. Therefore, the same UEID (corresponding PO) may appear twice in a paging cycle but in different time units, such as time slots. The UE can be woken up twice to listen to "different" POs. However, in some methods, the UE listens to only one PO per DRX cycle in idle mode. Therefore, the UE can perform at least one of the following operations:

[0264] Option 1: If the UE is an NES UE, and if the UE has received a DCI indication for paging adaptability / adaptability, the UE performs a PDCCH / paging message search according to the new paging configuration.

[0265] Option 2: If the UE is an NES UE, and if the UE receives a DCI indication for paging adaptability / adaptability, the UE can perform PDCCH / paging message search according to the new paging configuration and the traditional paging configuration. This process can be regarded as paging repetition, which can increase the accuracy of the results and reduce paging missed detections.

[0266] Scenario 4: Paging is in an adaptive / adaptive paging configuration, and the SSB is in an adaptive / adaptive configuration.

[0267] In this case, paging adaptability / adaptability and SSB adaptability / adaptability can be indicated by a single DCI instruction. If the NESUE receives this instruction, measurements are performed directly according to the adaptable / adaptable SSB configuration and adaptable / adaptable paging. In this case, a relaxation factor M1 can be set according to different conditions, which are determined by T. SMTC_NES The adaptive paging cycle PO_NES and at least one of the DRX cycles are determined. For example: if (T SMTC_NES If X4 > Y3 and DRX cycle ≤ Y3, M1 = C; otherwise, M1 = 1. C is a number greater than 1, such as 1.5 or 2. The criterion for determining the above thresholds X4 or Y3 is: to avoid losing all measurement opportunities while ensuring synchronized paging reception in the next DRX cycle. Relaxation factor M2 determination for intra- and inter- frequency NES neighbor cell measurement Figure 15 .

[0268] Assuming M2 is a relaxation factor considered in intra-frequency and inter-frequency neighboring cell measurements, the relaxation factor M2 can involve the following aspects:

[0269] Scenario 1: The serving cell is a regular cell, and the neighboring cell is an NES cell (regular cell → NES cell).

[0270] Scenes such as Figure 10 As shown, the NES cell in scenario 1 is an NES-only cell.

[0271] Because the SSB distribution period of ordinary cells is more dense than that of NES cells, it is a switch from short period to long period / new SMTC mode.

[0272] A. For NES-only cells (such as...) Figure 9 NW may be equipped only with SSB / paging configurations that conform to NES cells, such as adaptive / adaptive SSB / paging configurations.

[0273] Option 1: If the SMTC period of the NES SSB is a subset of the smtc2-LP-r16 configuration, and smtc2-LP-r16 exists, then when the NES UE reselects to a neighboring cell, it will follow the behavior of smtc2-LP-r16.

[0274]

[0275] The relaxation factor M2 can be set to a value greater than 1. For example, M2 can be selected as 1.5 or 2. For example, when DRX = 320 ms, if the SMTC period of the in-band cell under test > the third threshold (related to the RF chain on-time), such as 20 ms, then M2 is a value greater than 1, and M2 can be selected as 1.5 or 2; otherwise M2 = 1;

[0276] Option 2: If the NES's T SMTC_NES is sparser, or a new pattern is defined, it cannot be a subset of the smtc2-LP-r16 configuration at this time. For example, a new IE can be defined, and the name can be smtcNES-r19 or other names. This IE can contain sparser or new pattern SMTC configurations (such as new offset or duration) and the NES cell pci-List. The SSB-related configuration of this NES can be broadcast through SIB2 or SIB4. For example:

[0277]

[0278] At this time, the determination of the M2 condition is related to at least one of the DRX period, the time when the RF remains on (e.g., RF processing time), and the T SMTC and T SMTC_NES in the measured in-band / inter-band cells.

[0279] There may be the following situations: 20 ms < T SMTC < T SMTC_NES ,T SMTC ≤ 20 ms < T SMTC_NES ,T SMTC_NES ≤ 20 ms (such as when the SSB_NES distribution is denser).

[0280] For example, the relaxation factor can be set as follows: when DRX = 320 ms, if the T SMTC_NES < Y4 of the in-band cell under test, then M2 = 1; otherwise M2 is a value greater than 1, for example, M2 = 1.5 / 2.

[0281] B. For NES cells (as shown in Maximum interruption at paging reception ), since this cell can serve traditional UEs and NES UEs, both smtcNES-r19 and smtc2-LP-r16 can exist. For the selection of SMTC, NES UEs can preferentially select the configurations in smtcNES-r19, or it can be completely based on UE implementation (The selection of SMTCs to be used is up to UE implementation).

[0282] When the SMTC period of an NES cell is greater than the DRX period, a new DRX ratio can be introduced. This DRX ratio, along with the DRX period and the T of the intra-frequency or inter-frequency cell under test, are considered together. SMTC_NES and T SMTC Relevant. For example, the relaxation factor can be set to: The operator can be one of, max, min, or least common multiple. Case 2: The serving cell is an NES cell, and the neighboring cells are ordinary cells (NES cell → ordinary cell).

[0283] It's a switch from long-cycle / new SMTC mode cycle to short-cycle cycle.

[0284] The possible scenarios at this point include:

[0285] T SMTC The fifth threshold (the fifth threshold is related to the RF chain open time, taking 20ms as an example), T SMTC_NES <T SMTC <20ms, 20ms <T SMTC <T SMTC_NES The relaxation factor can be set to:

[0286] When DRX = the sixth threshold, for example, 320ms, if the T of the cell within the measured frequency range... SMTC The fourth threshold (related to the RF chain open time), for example, 20ms, then M2 is a number greater than 1, such as 1.5 or 2; otherwise M2 = 1.

[0287] √ Measurement result averaging method for different SSBs (default SSB / existing SSB and adaptable / adapted SSB)

[0288] This primarily applies to the transition from a regular cell to an NES cell. If the cell being reselected is an NES cell, then the T value of the target cell... target_cell_SMTC_period T configured by neighboring cells SMTC_NES and / or T SMTC Confirmed. The maximum interrupt time at this point can be:

[0289] T SI-NR +2*operator(T target_cell_SMTC_NES_period ,T target_cell_SMTC_period )ms.

[0290] Among them, T SI-NR =T MIB +T SIB1

[0291] T SI-NR The time required to receive all relevant system information data is determined by the acquisition time of MIB and SIB1.

[0292] The system information received by paging is provided by SIB1, and the scheduling of SIB1 is provided by MIB.

[0293] Operator can be one of the following: least common multiple (LCM), max, or min.

[0294] √ Measurement interval:

[0295] It can average the measurement results of different SSBs, such as SS-RSRP / SS-RSRQ and NES_SS-RSRP / NES_SS-RSRQ results.

[0296] When measuring and assessing service areas, the main measurement requirements are:

[0297] A. Measurement interval, which refers to how often measurements are taken:

[0298] B. Averaging of measurement results, involving the number of samples used for averaging and how the averaging is performed:

[0299] For measurement averaging: For NES scenarios, the measurement interval can be related to at least one of the following:

[0300] Relaxation factors M1, N1 (beam scanning factors for FR2), DRX period, T SMTC_NES With the second SSB cycle. It can be:

[0301] The UE should measure the SS-RSRP and SS-RSRQ levels of the serving cell and evaluate the cell selection criteria defined for the serving cell in TS 38.304 at least once every M1*N1DRX period*β; where:

[0302] M1 can be: if (T) SMTC_NES If X1 > Y1 and the period of DRX is less than or equal to Y1, then M1 is a value greater than 1, for example, M1 = 2; otherwise, M1 = 1.

[0303] β: DRX cycle length ratio, which can be equal to B in the following formula, taking values ​​of (0,1). This is because a new SSB mode may be introduced, and the second SSB cycle or T... SMTC_NES If the measurement interval is smaller than the existing DRX period, a new granularity can be introduced. In addition, the measurement interval does not have to be DRX / 2.

[0304] The new granularity can be correlated with the DRX cycle length, T SMTC__NES T SMTC It relates to at least one of the following. The new granularity can be B = mod(DRX cycle length / operator(T)). SMTC_NES, TSMTC `operator` is an operator that can be at least one of the following: one of, LCM, min, max. Alternatively, the new granularity can only be related to T. SMTC_NES Related, for example, B = mod(DRX period length / T) SMTC_NES )

[0305] Figure 16 like Figure 17 As shown. Because after the UE receives the adaptive / adaptive DCI, both the traditional SSB and the adaptive / adaptive SSB may exist simultaneously within the measurement averaging window. The RSRP / RSRQ calculated by these two SSBs may not be at the same level.

[0306] To achieve a fair comparison, the old RSRP / RSRQ is calculated using the last available traditional SSB, while the first RSRP / RSRQ is calculated based on the first adaptable / adaptive SSB, resulting in a shorter SSB period than the previous SSB period. A weighted average of the two results needs to be introduced, for example, using the following formula to obtain the average measurement result:

[0307]

[0308] Where S is the total number, depending on how many samples need to be considered for the measurement average. The selection of S is related to the adaptable / adaptive SSB configuration, and must be at least 2.

[0309] SS-RSRP k The k-th RSRP measurement result of traditional SSB;

[0310] NES_SS-RSRP m It can adapt to / adapt to the m-th RSRP measurement result of SSB; ε k The weighted value of the measurement results from a traditional SSB is between 0 and 1 to compensate for different transmission powers. K indicates that several previous measurements (such as those from a traditional SSB) need to be averaged. This can be a network-configured value, such as 1, or indicated by a DCIbit.

[0311] γ m : The weighted value of the measurement results for adaptability / adaptability to SSB, between 0 and 1, to compensate for different transmit power. M indicates how many NES_SS-RSRP measurement results need to be averaged, which can be a network-configured value, such as 1, or indicated by DCIbit.

[0312] c: Whether to consider previous measurement results can be indicated via DCI. This DCI can be an indication of SSB adaptability / adaptability. 1: Indicates averaging is required; 0: Indicates averaging is not required. Alternatively, the network can broadcast information directly via SIB.

[0313] ●UE behavior under cell selection and cell reselection

[0314] The various parameters discussed above can affect the measurement / evaluation requirements during cell selection or cell reselection, as shown in the table below:

[0315] Service cell measurement and evaluation cycle N serv ,

[0316] Scenario 1: For UEs supporting NES, the evaluation time setting is based on the DRX period and can be determined based on the DRX scaling factor, scaling factor, and relaxation factor, as shown in Table 1 below:

[0317] Table 1: Evaluation time N for UEs supporting NES serv_NES

[0318]

[0319] δ represents the DRX scaling factor, etc., and takes a value of (0,1). It is related to the DRX period, T SMTC_NES ,T SMTC It is related to at least one of them. It can be...

[0320] Scenario 2: The evaluation of NES cells is based on a new granularity, as shown in Table 2 below:

[0321] Table 2: Evaluation time N for UEs supporting NES serv_NES

[0322]

[0323] B = mod(DRX cycle length / operator(T)) SMTC_NES, T SMTC )), where operator is an operator that can be at least one of the following: min, max.

[0324] ●The following will use the new cell search process as an example to illustrate the changes in the entire process. Example process as follows: Figure 17

[0325] As shown.

[0326] Figure 17 The process involved may not be the initial access; the UE may already be registered with a PLMN. For example... Figure 24 As shown, the cell search process may include at least some of the following steps:

[0327] Step 1: Because it is an NES cell, the SSB period used for initial access in this cell will be sparse. Both NES and traditional UEs use the SSB of this sparse period for initial access, cell search, including downlink time / frequency synchronization using the sparse SSB configuration, confirming the cell ID, and decoding the PBCH for MIB acquisition, etc.

[0328] Step 2: NW broadcast system information and DCI 1_0.

[0329] DCI Option 1: SSB / Paging Adaptability / Adaptability Indication can be broadcast via DCI 1_0, and as previously mentioned, there are multiple designs.

[0330] As mentioned above, the adaptable / adaptation-related configurations can also be updated via SIB1.

[0331] Step 3: The NES UE receives the DCI and begins measurement using the adaptable / adaptive SSB after a certain period of time.

[0332] Step 4: The UE performs the cell selection process. The purpose of cell selection is to find the most suitable cell for the carrier frequency to camp on. The cell selection process includes cell quality measurement and evaluation.

[0333] In this step, as previously described, the NES UE can perform NES_SS-RSRP / NES_SS-RSRQ measurements based on different SSB-related configurations. The NES UE should measure the serving cell's NES_SS-RSRP and NES_SS-RSRQ levels and evaluate the serving cell's cell selection criteria at least once every M1*N1 DRX cycle*δ.

[0334] Step 5: The NES UE can listen to paging information in a suitable cell.

[0335] As mentioned above, NES users can listen for adaptive / adaptive paging configurations (if they receive adaptive / adaptive DCI) or traditional paging configurations.

[0336] After paging is received, the process can proceed to RRC connection establishment.

[0337] Measurement in connected mode

[0338] In Scheme 1, the UE receives the SSB adaptation instruction in time slot n before receiving the NES SCell activation instruction. After receiving the SSB adaptation instruction, the UE performs deactivation NESSCell measurements within a fast time window (FTW) based on the SSB cycle after SSB adaptation and reports the valid L3 measurement results. The fast time window and the measurement cycle based on the adapted SSB measurement resources are related to the reporting time of the corresponding valid L3 measurement results. The adapted SSB cycle is shorter than the default / existing SSB cycle and the existing configuration parameter measCycleSCell. If the UE fails to receive the SSB adaptation instruction, the UE uses the existing parameters measCycleSCell and DRX cycle for deactivation cell measurements.

[0339] If the UE receives a SCell activation command after reporting a valid result, and the known conditions of the NES SCell are met, the UE uses densely periodic adaptive SSB measurement resources for time / frequency tracking and / or fine AGC settings during the known NES SCell activation period.

[0340] ●The UE receives the SSB adaptation command in slot n. After the transition time T1 in slot n, the UE performs deactivation NES SCell measurement within the FTW based on the SSB cycle after SSB adaptation.

[0341] ■T1 relates to the additional processing / preparation time and the transmission duration from the receipt of the first complete SSB burst set after SSB adaptation. The UE determines the additional processing time based on: the RF / baseband parameter preparation time and the readjustment time of measurement resources after adaptation. Furthermore, the specific value of this additional processing time can be reported according to the UE's capabilities.

[0342] ● If the UE receives an NES SCell activation command within the last Xs of reporting valid results, and the measurement based on the adapted SSB remains detectable, the known conditions for the NES SCell are met. Here, Xs is related to the SSB adapted measurement resource cycle.

[0343] ● The UE utilizes densely periodic adaptive SSB measurement resources to reduce time / frequency tracking and / or fine AGC setting delays during SCell activation.

[0344] In Scheme 2, for unknown NES SCell activation, the UE receives the SSB adaptation indication instruction in time slot n simultaneously with the NES SCell activation instruction. Upon receiving both the SSB adaptation indication and the SCell activation instruction, during the NES SCell activation process, the UE performs AGC, cell detection, measurement, and time / frequency adjustment based on the SSB-adapted period. The SSB adaptation period depends on the specific adaptation mechanism and is shorter than the SMTC period.

[0345] ●Latency during L1-RSRP measurement by the UE using densely periodically adapted SSB measurement resource reduction during unknown NES SCell activation.

[0346] For the activation of multiple unknown NES SCells, the UE receives an SSB adaptation indication when it receives a multiple NES SCell activation command. When both the SSB adaptation indication and the multiple NES SCell activation command are received, the multiple SCells undergo additional delay extension based on the dense SSB cycle after SSB adaptation.

[0347] ● This delay spread includes interruption delay spread, which relates to the location of the interruption during activation and the multi-cell detection delay spread related to the number of unknown NES cells to be activated.

[0348] In Scheme 3, the UE receives an SSB adaptation instruction within one measurement cycle. After receiving the SSB adaptation instruction, the UE activates SCell measurements during the transition measurement cycle based on the SSB measurement resources before and after adaptation. After the transition measurement cycle, the UE performs measurements based on the adapted SSB measurement resources and reports the measurement results no later than the transition measurement cycle.

[0349] ●The measurement cycle after the transition period is related to the measurement resource cycle after adaptation, the DRX cycle and the NESCSSF parameter. The CSSF depends on the frequency position relationship before and after adaptation.

[0350] Regarding Scheme 1 and Scheme 2, further integration is needed. Figure 24 explain.

[0351]

[0352]

[0353] 1. Beneficial effects of SCell operation based on adaptive SSB: The adaptation of SSB in the time domain can provide more sleep opportunities for NW and achieve considerable energy savings in gNB for different traffic loads.

[0354] 2. Benefits of Fast SCell Activation: It addresses the power consumption and performance degradation issues associated with slow SCell activation, as well as the low throughput caused by slow / failed SCell scheduling. Fast SCell activation can achieve high throughput performance in NES scenarios.

[0355] In connected mode, the adaptable / adaptive transmission of SSB can also be monitored.

[0356] NW uses a set of SSB configurations (e.g., dense SSB configurations, including the bias between adaptive / adaptive SSBs and traditional SSBs). How and when NW triggers / activates / enables the adaptive / adaptive SSB configuration can be configured or indicated using low-level signaling such as L1 DCI or L2 MAC-CE.

[0357] NW configures two SSB configurations (e.g., including a traditional SSB configuration and an adaptive / adaptive SSB configuration), and specifies how and when NW triggers / activates / enables the adaptive / adaptive SSB configuration.

[0358] Option 1: Update based on RRC messages, such as RRC Reconfiguration;

[0359] 2. Option 2: NW activates adaptable / adaptive configuration via MAC-CE command.

[0360] 3. Option 3: DCI.

[0361] Option 2 and Option 3 involve different transition times (also known as conversion time or conversion cycle).

[0362] Regarding option 2:

[0363] The NES UE uses the default SSB configuration before time T1, such as a sparser SSB period of 80ms for L1 measurement. After receiving the PDCCH at time T1, the NES UE is ready to receive adaptive / adaptive SSBs (which may be smaller period SSBs or new SSB patterns) at time T2.

[0364] The total delay of the adaptable / adaptive SSB from T1 to T2 that can be used for L1 measurement (i.e., the transition time described later, which can be expressed as Y5)

[0365] The purpose of the Y5 ms interval is: if the UE uses the adapted SSB resources to perform deactivation SCell measurements within the FTW, the UE should know the location of the first "allowable / permissible" adapted SSB burst. The time interval between the UE obtaining the above information is the transition time.

[0366] Definition of conversion time or conversion cycle:

[0367] A. Starting point: SSB adaptation indication commands are received from the following sources (RRC reconfiguration on PDSCH; MAC-CE under PDSCH; DCI on PDCCH).

[0368] B. End Point: NES-capable UEs are able to receive the first complete adaptive SSB burst on the SCell.

[0369] The conversion time can consist of at least one of the following:

[0370] 1) HARQ ACK time delay of PDSCH ((K1+1)TTI)

[0371] 2) Signal decoding / processing time

[0372] 3) Additional processing / preparation time, which may include at least one of the following:

[0373] 3-1) Software overhead to baseband (BB) / RF programming time

[0374] 3-2) Radio Frequency Retuning Time

[0375] 3-3) Redundancy for wireless link configuration

[0376] 3-4) Searcher scheduling time is limited by the searcher.

[0377] For the following different adaptation scenarios, NES-capable UEs can flexibly receive adapted SSBs in the SCell, such as... Figure 20 As shown.

[0378] Scenario 1: The SSB adaptation command is received after the SSB transmission in the SCell. The adapted SSB and the traditional SSB have the same carrier frequency (same center frequency and bandwidth), but different periods.

[0379] Scenario 2: The SSB adaptation command is received after the SSB transmission in the SCell. In this case, the adapted SSB and the traditional SSB have different carrier frequencies. For example, a new SSB carrier frequency is added for the same PCI (Physical Cell Identifier).

[0380] In this case

[0381] 1) For a newly added SSB carrier frequency of the same PCI (e.g., referred to as the second SSB frequency), additional time can be added for RF / BB preparation and RF retuning (e.g., this additional time can be 1ms);

[0382] Additional processing / preparation time can be defined as...

[0383] 1) UE capability accompanied by candidate values ​​{0, 1, 2, 3, 4, 5} ms

[0384] 2) It can be predefined as a value that includes all additional processing time, such as 5ms.

[0385] If the NES UE receives an adaptive / adaptive deactivation MAC CE command at time T3, the NES UE retains the L1 measurement results calculated by NES_SSB, but can release the associated adaptive / adaptive SSB configuration. After, for example, T... HARQ After a transition period of +MAC CE processing time (e.g., 3ms) + the transition time, the NES UE can continue L1 measurements using the default SSB configuration. If the NES UE receives the SSB adaptability / adaptability deactivation indication carried by RRCReconfiguration at T3, after a certain period of time (e.g., Z ms), the NES UE can continue L1 measurements using the default SSB configuration. This Z ms includes the RRC message (e.g., the RRCReconfiguration mentioned above) processing delay.

[0386] A. In one implementation, the MAC-CE is a newly defined MAC-CE command specifically designed to activate SSB adaptability / adaptability, or it can be achieved by adding new content to the existing MAC-CE, or by using a newly defined MAC-CE instruction (including a new index and / or LCID (The Logical Channel ID) value).

[0387] B. When the UE receives multiple MAC-CE commands, but the MAC-CE for SSB adaptability / adaptability does not arrive at the same time as other MAC-CEs (such as MAC-CE SCell activation instructions), at k0+T HARQ In addition to +3ms, a certain duration (e.g., Z_1ms) is required before adaptive / adaptive SSB can be used for normal L1 measurement.

[0388] The first NES_SSB reception time indicated by NES_SMTC: T FirstNES_SSB_multiMAC-CE . Regarding option 3:

[0389] SSB adaptability / adaptability configuration can be activated via DCI format X_X with S-RNTI or a new RNTI. In one implementation, the new DCI field or bit word can directly indicate the adaptable / adaptable SSB mode or period, or its time-domain or frequency-domain (mapping) relationship with existing resources. In another implementation, the DCI uses bit words to provide an index indicating the corresponding available resources. Regarding the L1-RSRP results measured using NES_SSB

[0390] Regarding the average of the measurement results:

[0391] Because the L1-RSRP strength measured using the NES_SSB (also known as the adapted SSB or adaptive SSB / SSB adaptation) and the default SSB may differ, to ensure comparability of receive performance, the L1-RSRP value measured by the NES_SSB can be multiplied by a factor β. β can be obtained by combining the L1-RSRP calculated from the last default SSB and the L1-RSRP calculated from the first valid adaptive SSB. A valid adaptive SSB refers to the aforementioned adaptive SSB that can actually be used for L1-RSRP measurement.

[0392] Resource overlap during L1 measurement

[0393] 1. SSB and NES_SSB time domain overlap

[0394] A. Different SSB configurations overlap in the time domain (OFDM symbol overlap), and the measurement limitations are as follows:

[0395] Because two SSB configurations are active at this time, the adaptive / adaptive SSB and the default SSB, these two SSBs can be FDMed (e.g., the adaptive / adaptive SSB in compact mode overlaps with the default SSB in the time domain). In this case, the measurement behavior of the NES UE can include:

[0396] 1) Receive two types of SSBs simultaneously using the same RX chain and perform L1 measurements separately. If L1-RSRP measurements are performed simultaneously, the two measurement results can be saved, or only the larger one can be saved. This behavior depends on the UE implementation.

[0397] For example, the UE should be able to measure SSB and NES_SSB for L1-RSRP measurements without any limitations.

[0398] 2) Receive both types of SSBs simultaneously using the same RX chain, but only measure and save the measurement results related to the NES SSB, L1-NES_RSRP.

[0399] 3) Use an Rx chain to receive only one type of SSB and perform measurements.

[0400] For 2) and 3), a relaxation factor a can be added to extend the measurement period.

[0401] B. NES_SSB and SSB overlap from two cells (between cells) or multiple panel cells:

[0402] The following relaxation factor P1_NES can be considered to extend the measurement delay. P1_NES can be derived from the second SSB period, the first SSB period, and the shared factor P when the SSB overlaps with SMTC and MG. 1_1 (i.e., P1 as defined in the existing standard), the shared factor P when NES_SSB overlaps with NES_SMTC and NES_MG. 2_1 Therefore, the relationship can be defined as follows:

[0403]

[0404]

[0405] When B.NES_SSB, NES_SMTC and NES_MG overlap, the following relaxation factor P can be used. 2_1 Extend the measurement.

[0406] Case 1: If in the second SSB period, T SMTC_NES These are the first SSB cycle and T. SMTC A subset of. Based on the overlap between the SSB, SMTC, and MG, the NES UE can follow the requirements associated with the traditional or default SSB.

[0407] Case 2: If in the second SSB period, T SMTC_NES If a new period is defined, such as <5ms or >160ms, or a new pattern is defined, then the sharing factor P1 will be related to the second SSB period, T. SMTC_NES If it is related to at least one of NES_MG, then P needs to be defined. 2_1 For TCI state switching based on MAC-CE

[0408] For a known Transmission Configuration Indicator (TCI) state, a TCI state switching command is received within a first duration, wherein the first duration is related to T... SMTC_NES and / or T SMTC Relatedly, the first duration can be represented as 8*operator(T) SMTC_NES ,T SMTC ), operator can be max or min.

[0409] For an unknown TCI state, because additional L1-RSRP measurements are required, the time T3' for receiving the TCI state switching command can be expressed as:

[0410] (L1-RSRP measurement time based on the first SSB, L1-RSRP measurement time based on the second SSB) + TO uk *(T first-NES_SSB +TSSB_NES-proc +T SSB_NES-use ms) / NR slot length.(1)

[0411] explain:

[0412] The L1-RSRP measurement time based on the first SSB can be T. L1-NES_RSRP， The L1-RSRP measurement time of the NES SSB is indicated; the NES SSB can be one of on-demand SSB, SSB adaptable, or adaptable / adaptive SSB; in this disclosure, for ease of description, "adaptive SSB" or "SSB adaptable" is used as an example, and the "adaptive SSB" mentioned in the description can also be replaced by "adaptive SSB" or "adaptable / adaptive SSB".

[0413] The L1-RSRP measurement time based on the second SSB can be T. L1_RSRP， Indicates the use of the default / existing SSB for L1-RSRP measurement time.

[0414] operator(): As mentioned above, the NES UE can use at least one of SSB adaptation, on-demand SSB, and SSB to perform L1-RSRP measurement, therefore the result of operator can be T L1-ondemandSSB_RSRP , and / or T L1-NES_RSRP or T L1_RSRP Alternatively, the maximum or minimum value among the three can be chosen.

[0415] T first-NES_SSB : This refers to the time of the first SSB transmission after the MAC CE command is decoded by the UE.

[0416] T SSB_NES-proc The processing time of the first SSB, for example, 2ms.

[0417] T SSB_NES-use The time for using the new NES_SSB to perform AGC setup and time / frequency fine synchronization can be 3ms.

[0418] TO uk: The value is 1 if the target TCI is not in the list of TCI states activated for PDSCH, otherwise it is 0.

[0419] Subframe slot indication.

[0420] Examples of measurement latency requirements for NES UEs are shown in Tables 4 and 5.

[0421] Table 4: Measurement period T for FR1 L1-RSRP_Measurement_Period_NES_SSB

[0422]

[0423] The first SSB cycle can be T. SSB The second SSB cycle can be T. NES_SSB Or T on-demand_SSB ;T on-demand_SSB It is another SSB configuration.

[0424] Table 5: Measurement period T for FR2 L1-RSRP_Measurement_Period_NES_SSB

[0425]

[0426] explain:

[0427] 2) operator1(first SSB cycle, second SSB cycle), where operator is the operator, the result can be one of the following: first SSB cycle, T NES_SSB , max(first SSB cycle, second SSB cycle), min(first SSB cycle, second SSB cycle), LCM(first SSB cycle, second SSB cycle);

[0428] 3) P is the scaling factor, and P1_NES and / or P 2_1 related;

[0429] 4)opertor2(T DRX The second SSB period may be used for calculations because it may be shorter than the DRX period. Here, opertor2 can be either max or min.

[0430] 5) c refers to the relaxation factor. SSB and NES_SSB (which have different modes) overlap in the time domain. The relaxation factor when measuring these two SSBs simultaneously can be a value greater than 1, such as 1.5, to ensure measurement opportunities.

[0431] For the L1 measurement steps of NES UE, an example procedure is as follows: Figure 6 As shown, at least some of the following steps are involved:

[0432] Step 1: UE capability information query;

[0433] Step 2: UE capability reporting;

[0434] Step 3: RRC measurement configuration.

[0435] In an NES cell, the network is configured with two SSB configurations. One is the traditional SSB configuration, serving traditional users and NES-enabled UEs. The additional SSB configuration only serves NES-enabled users. This additional configuration is an adaptive / adaptive SSB configuration. If the adaptive / adaptive SSB is only transmitted for a continuous period of time, it can be called an on-demand SSB. For RRM measurements including intra-frequency measurements in this patent, a NES-specific SMTC configuration is required. The relationship between configuration and activation / indication is as follows: An NES-related SMTC configuration with multiple candidate parameters is configured in the RRC, and the flexible configuration configured in the RRC is dynamically indicated using DCI and / or MAC-CE. The adaptive SMTC in the RRC (i.e., T) can be obtained according to one of the following three possible methods. SMTC_NES explain):

[0436] 1. Obtain from the same MeasObjectNR as traditional SMTC, and define the NES SMTC list.

[0437] If SMTCNES higher-layer signaling is configured, for the cell indicated in the pci-list parameter in SMTCNES, if a UE with NES capability receives an SSB adaptation indication in time slot n, it can perform measurements using the SMTC periodicity and / or SSB symbol corresponding to the SMTCNES value after time slot n+X ms.

[0438] 2. Obtain from NES-specific MO

[0439] Challenges include: 1) L3 cell-level measurements between different measObjectIds; 2) New mechanism: Reporting of measurements triggered by NES using measObjectId;

[0440] 3. Obtain from the relevant configuration SCellConfig of the serving cell.

[0441] Two possible ways to indicate NES-related configurations: 1) Explicitly indicate the permissibility of additional resources with 1 bit;

[0442] 2) Multi-bit indicator candidate configuration index

[0443] Specifically: Configure multiple candidate parameters in the RRC and use DCI / MAC-CE to flexibly indicate one or more RRC configurations.

[0444] The reason for considering additional adaptive SMTC configurations is that a single SMTC cannot quickly adapt to changes in the SSB cycle. This mismatch between the fixed SMTC and the adaptive SSB can prevent the UE from obtaining accurate and rapid measurement results for the considered cell.

[0445] Problem to be solved: SMTC configuration needs to be quickly adapted and aligned with different SSBs.

[0446] Beneficial effects: Immediately measures and reports busy traffic; improves throughput performance.

[0447] Step 4: NW transmits SSB resources for L1-RSRP measurement. Measurement begins when the UE receives the first reference signal.

[0448] At this point, during this process, NW can activate SSB adaptability / adaptability configuration by sending a MAC-CE command, or by triggering SSB adaptability / adaptability configuration using DCI.

[0449] The UE performs measurements based on NES_SSB and / or the default SSB, according to the aforementioned measurement description and measurement limitations.

[0450] It is worth noting that after receiving the corresponding MAC-CE / DCI, a transition period must be allowed before NES_SSB can be used for measurement.

[0451] If the NES UE misses the corresponding DCI instruction, it will still follow the process related to the default SSB, perform relevant measurements based on the SSB, and not consider the newly defined transition time.

[0452] Step 5: The NES UE reports the measurement results no later than time T2, which follows the measurement cycle configuration in Tables 4 and 5 above.

[0453] Step 6: The NES UE receives the TCI handover instruction, expected to be within a fixed 8*operator(T SMTC_NES ,T SMTC ) received within;

[0454] Step 7: When the TCI state is known, the UE receives the PDCCH with the new TCI state within T3 ms;

[0455] Step 7': For unknown TCI state switching, NES UE needs to perform additional L1-RSRP measurement and receive PDCCH with new TCI state in T3', T3' refers to the above (1) formula.

[0456] Similarly, the CBD requirements based on the adaptation SSB are defined as follows:

[0457] Table 3: Evaluation period T for FR2 Evaluate_CBD_NES SSB

[0458]

[0459] In multi-carrier scenarios, adaptive / adaptive SSBs are used to operate SCells. SCells include NES-only SCells serving only NES users, and NES SCells serving both NES and regular users. Measurement operations on SCells include L1 and L3 (layer 3) measurements. L3 measurements include measurements on deactivated SCells and L3 measurements for intra-frequency serving cells after SCell activation. L1 measurements include L1-RSRP, L1-SINR, CBD measurements, etc.

[0460] A diagram illustrating the operation of an adaptive SSB (or an adaptable SSB) on a SCell is shown below. Figure 24 As shown.

[0461] Based on receiving SSB adaptation indications at different locations (e.g., ... Figure 24 Positions 1, 2, and 3 shown can be adjusted using different criteria for shortening or extending the SCell activation time. Combined with... Figure 6 The examples for positions 1 and 2 are summarized as follows:

[0462] Table 9. Principles for Adjusting the Location and SCell Activation Time of Received SSB Adaptation Instructions

[0463]

[0464] The SSB time-domain adaptation indication positions can be #1, #2, and #3, corresponding to SSB time-domain adaptation indication positions #1, #2, and #3 in the diagram, respectively. This can be indicated via DCI or MAC-CE. After receiving the SSB time-domain adaptation indication at the corresponding position, the UE can receive the first allowed SSB resource after completing the signaling processing time and additional processing time, and then begin subsequent measurements according to the indicated SSB configuration. The SSB time-domain adaptation indication position can correspond to the corresponding SSB configuration and the corresponding adaptable / adaptive SSB transmission method, for example... Figure 25 As shown, SSB time domain adaptation indicator position #1 can correspond to adaptable / adaptable SSB transmission mode #1, SSB time domain adaptation indicator position #2 can correspond to adaptable / adaptable SSB transmission mode #2, and SSB time domain adaptation indicator position #3 can correspond to adaptable / adaptable SSB transmission mode #3.

[0465] ● Location #1 occurs during the measurement of the deactivated cell. If an NES-capable UE receives an SSB time-domain adaptability / adaptability indication from a DCI at location #1 (this DCI can be issued by the PCell), it will begin receiving adaptable / adaptable SSBs after k0 + X3 + Δms (as mentioned earlier, k0 can be the time to decode the PDCCH to obtain the scheduled PDSCH), where X3 can be assumed to be the DCI 2_9 processing time, following Table 11, and Δ is the additional processing time. This additional processing time can be predefined as a fixed value of 5ms or 3ms, or based on the UE capability reported.

[0466] The NES UE measures the deactivated SCell within the fast time window (FTW) based on the received adaptive / adaptive SSB (NES_SSB) or SMTC_NES configuration parameters, and reports the quality of the SCell.

[0469] ■ Procedures that UE can perform

[0470] ◆Fast deactivation NES SCell measurement based on fast time window (FTW)

[0471] ◆Fast SCell activation based on rapid deactivation of NES SCell measurements, including determination of known NES SCell conditions.

[0472] ◆Furthermore, because NES UEs can also receive traditional SSB or SMTC configurations, the measurement cycle can still be measCycleSCell, meaning that measurements are performed using traditional methods. ●The #2 position occurs during SCell activation, indicating that the NES-capable UE simultaneously receives SSB time-domain adaptability / adaptability indication commands and SCell activation indication commands through different instructions. If NES

[0473] After a capable UE receives an SSB time-domain adaptability / adaptability indication activated by MAC / DCI at position #2, it will begin preparing to receive adaptability / adaptability after the transition time (or transition period).

[0474] SSB is used for L3 / L1 measurements, AGC adjustments, time-frequency synchronization, etc., and performs rapid new channel quality indication (CQI) reporting to enable fast SCell scheduling and subsequent data transmission. Furthermore, the NES UE is activated upon receiving the SCell activation indication command.

[0475] SCell shall report the cell CQI no later than the D2 time slot.

[0476] ■ Procedures that UE can perform

[0477] ◆Fast single unknown NES SCell activation based on adapted short-cycle SSB measurement resources

[0482] SSB adaptation adjustment to another large cycle. Use an adaptable / adaptive SSB and / or a traditional SSB for L1 measurement, or use SMTC_NES and / or SMTC for L3 measurement.

[0483] in addition,

[0484] 1. The measurement target configuration information may include: same-frequency measurement configuration information;

[0485] 2. For additional SSB resource configurations (e.g., how to achieve SSB cycle adaptability / adaptability through one or more SSB cycle values):

[0486] Implementation Method 1: Based on the default SSB configuration (e.g., period) and combined with additional adjustment parameters, achieve adaptability / adaptability.

[0487] 1) If the default SSB configuration is a traditional SSB cycle, such as 20ms or 40ms, the additional configuration can be 5ms or 160ms. The network can adapt the SSB cycle from the traditional cycle to the additional cycle through DCI according to task requirements. It can also achieve sparse SSB transmission / long SSB cycle by blocking / silencing certain SSB transmissions to obtain power saving gains.

[0488] 2) If the network defaults to a long SSB period configuration to achieve power saving gains, then when rapid measurement is required, the existing SSB configuration period can be scaled / adjusted (this can be achieved by configuring and instructing the network to adjust the parameters), and a timing / frequency offset can be added (for example, the timing deviation between the adjusted SSB and the original SSB can be configured and indicated by the network; in a SCell activation scenario, this timing offset can be the time-domain position deviation between the adjusted SSB and the PCell SSB, or the time-domain position deviation between the adjusted SSB and the original SCell SSB). This will result in dense SSB transmission / short SSB period. The NW activates or instructs the UE to change the SSB period via MAC-CE / DCI.

[0489] Implementation Method 2: Directly provide two SSB configurations to achieve adaptability / adaptability. The transmission periods for SSBs are completely different in these two configurations. The positions where SSBs are transmitted within a half-frame can be the same or different (e.g., the temporal positions of SSBs transmitted in an SSB burst can be the same or different). For example, the SSB modes can be the same or different. Both configurations can be used simultaneously.

[0490] Implementation Method 3: A default long-period SSB configuration combined with discontinuous transmission (DTX) enables SSB transmission with different periods. For example, one SSB period is used during DTX active periods, and another SSB period is used during DTX inactive periods, with one of these SSB periods being the default long-period SSB. In this patent application, the default long-period SSB can also be referred to as the traditional SSB period.

[0491] The overall steps are as follows:

[0492] Step 1: The NES capable UE receives measurement configuration information via RRC commands.

[0493] Step 2: Request the NES-capable UE measurement results to be reported via the network.

[0494] Step 3: Based on the measurement results, NW configures the SCell parameter for the NES capable UE. This parameter can be reflected in the SCellConfig configuration.

[0495] Additional configuration parameters may include, but are not limited to, at least one of the following: 1) Timing / frequency deviation between the adaptable / adaptive SSB and the traditional SSB (including SSBs on PCell and SCell); 2) Transmission period of the adaptable / adaptive SSB; 3) Adaptable / adaptive measurement timing configuration related to the transmission of the adaptable / adaptive SSB (e.g., SMTC_NES); 4) Parameter information for scaling / adjusting the existing SSB configuration period (e.g., parameter information related to the time domain and / or frequency domain of the adaptable / adaptive SSB configuration); 5) Enhanced DTX (Discontinuous Transmit / Receive) parameter information, such as DTX period specifically considered for NES_SSB transmission, DTX start duration timer, DTX inactivity duration timer, etc.; 6) Time domain location of the adaptable / adaptive SSB transmitted in an SSB burst; 7) Pattern of the adaptable / adaptive SSB; 8) Correspondence between the adaptable / adaptive SMTC and the adaptable / adaptive SSB.

[0496] Step 4: The NES UE performs measurements on the deactivated SCell within the FTW based on the SCell configuration information. This is compared to existing SMTC-based measurements. Figure 26 As shown.

[0497] ●Process:

[0498] ■Step 4-1: After the UE receives the SSB adaptation instruction, the UE performs a fast deactivation measurement of the SCell within the FTW based on the adapted SSB.

[0499] ◆This FTW is a one-shot operation and is related to the start point, end point, and length.

[0500] ◆ The length and transition time of FTW are related to the deactivation cell measurement or detection time based on the adapted SSB cycle, and the L3 measurement reporting cycle based on the adapted SSB cycle.

[0501] ■Step 4-2: After FTW, the UE performs deactivation cell measurements based on the traditional parameters measCycleSCell and DRX.

[0502] ●Further energy savings: Spacing T_FTW between multiple FTWs

[0503] To further conserve network (NW) energy, an interval T_FTW can be defined between multiple FTWs. The starting point of T_FTW is the time when the UE receives the SSB-adapted deactivation instruction (or SSB-adapted deactivation indication command), and the ending point of T_FTW is the time when the UE receives the SSB-adapted activation instruction (or SSB-adapted indication command) again. The granularity of the time can be various suitable time units, such as time slots, symbols, or absolute time (e.g., milliseconds).

[0504] The advantage of defining the starting point of T_FTW as the point at which the UE receives the deactivation instruction adapted by the SSB is that:

[0505] Achieving a trade-off between target NW energy saving and UE measurement / detection performance based on adaptive SSB ● Applicable scenarios:

[0506] For fast deactivation SCell measurement based on FTW, applicable scenarios include... Figure 19 As shown

[0507] ■Scenario 4: Fast Deactivation NES Cell Measurement Based on FTW

[0508] ◆Within FTW, UE performs fast NES SCell measurements based on dense cycles adapted to SSB.

[0509] ● Location for receiving the SSB adaptation deactivation command: before the UE receives the SCell activation command. ◆ After FTW, the UE reverts to the slow measurement mode related to the traditional parameters measCycleSCell and DRX.

[0510] ◆T_FTW Limitation in Multiple FTW Scenarios: After T_FTW, the UE performs a new round of fast deactivation SCell measurement based on dense SSB cycles.

[0511] ■Scenario 5: Fast Deactivation Measurement and Fast NES Cell Activation Based on FTW

[0512] ◆ Within the fast time window, the UE performs fast deactivation NES SCell measurement based on the dense SSB cycle after SSB adaptation.

[0513] ◆ Within X seconds before receiving the NES SCell activation command, the UE reports valid measurement results. ● The position where the SSB adaptation deactivation command is received: within the next SCell deactivation state, where the determining factors of X are related to FR1 and FR2.

[0514] The FR1:X parameter is related to the configured DRX cycle and measCycleSCell parameters. For example, it can be defined as max(5*measCycleSCell, 5*DRX cycles).

[0515] For FR2: It is related to the acceptable time jitter for different power classes, for example, it can be defined as: 4s for UE supporting power class 1 or 5; and 3s for UE supporting power class 2, 3, or 4.

[0516] Regarding the starting point of FTW, in one implementation, FTW begins when the UE receives the SSB adaptation instruction, which includes:

[0517] ■ Transition Time

[0518] ■ Deactivation cell measurement or detection time based on the adapted SSB cycle

[0519] ■ L3 measurement reporting cycle based on the adapted SSB cycle

[0520] A. Deactivation cell measurement or detection time based on the adapted SSB cycle. Here, the measurement time T is used as the basis. SSB_measurement_period_intra_NES For example, this section illustrates specific UE behavior, specifically targeting scenario 4: fast deactivation of NES SCell measurements based on FTW.

[0521] ■ Measurement sampling is related to at least one of the following: SSB period T after SSB adaptation SSB_NES Configure how many carriers need to be measured, and the NES SCell SSB measurement opportunities or timings interrupted by MG.

[0522] ■SSB cycle T after SSB adaptation SSB_NES

[0523] ◆Change from measCycleSCell to T SSB_NES T SSB_NES <measCycleSCell

[0524] ◆If periodic adaptation is based on two SSB configurations, and both configurations are active, then (Default SSB cycle, Additional SSB cycles), where It is an operator, which can be used to find the minimum value.

[0525] ■ Configure the number of carriers to be measured, for example, expressed using the NES carrier-specific scaling factor (CSSF).

[0526] ◆CSSF NES =1, when the configured NES SCC is 1 or the NES SCC is the highest priority. The NES SCC being the highest priority can be communicated to the UE via network indication.

[0527] ◆Or CSSF NES =CSSFintraNES, assuming a searcher is used for all SCCs including NESSCC.

[0528] ■ The NES SCell SSB measurement opportunity interrupted by MG, scale factor Kp_NES

[0529] Kp_NES = Ntotal / Navailable

[0530] Ntotal: The total number of SSB measurement opportunities within the FTW window;

[0531] Navailable: The number of SSB measurement opportunities that do not overlap with MG within the FTW window;

[0532] ■ To ensure the accuracy of deactivated NES measurements: consider using a sufficient number of M samples to average the results as described above, where T... SSB_measurement_period_intra_NES Redefining:

[0533] T SSB_measurement_period_intra_NES =Ceil(M x Kp_NES)xT SSB_NES x CSSF NES

[0534] The adapted SSB period can be one of 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms (B). The L3 measurement reporting period T is based on the adapted SSB period. report_NES

[0535] It can be divided into event reporting or UE autonomous reporting of valid measurement results when the accuracy meets the following conditions: |SS-RSRP_NES|>pre-configured threshold;

[0536] Combining the transition time, the deactivation measurement period, and the L3 measurement reporting period of the NES SCell, the UE performs fast deactivation SCell measurements within the FTW during the following time periods.

[0537] D FTW = Transition period T1 + ρ(T) report_NES ,T SSB_measurement_period_intra_NES ), ρ is an operator that can be max of(·) or min of(·).

[0538] T_FTW (shown as T2 in the figure) limit when there are multiple FTWs: To further save NW energy, the restrictions on the UE and NW in T_FTW are as follows: The NW does not expect to retransmit the SSB adaptation indication command, so the UE does not expect to perform measurements for quickly deactivating the SCell based on the adapted SSB. Accordingly:

[0539] ■T Start -T end <T_FTW, T start : The time when the UE receives the retransmission of the SSB adaptation indication command; T end : The time when the SSB adaptation deactivation indication is received. "T start -T end " represents the time interval between T start and T end , for example, the time from T end to T start . T start -T end The limit of <T_FTW can indicate that starting from T end , within a time less than the time interval T_FTW, the NW does not expect to retransmit the SSB adaptation indication command, so the UE does not expect to perform measurements for quickly deactivating the SCell based on the adapted SSB;

[0540] ■ Conditions for defining T_FTW: The cell remains measurable and detectable; the reported measurement results meet the accuracy requirements

[0541] ■ Bad impacts if T_FTW is not defined: Inaccurate adaptation results based on SSB cannot ensure that the NES SCell has good enough channel conditions to quickly activate burst data traffic scheduling

[0542] Step 5: Activation of the SCell. Depending on whether the SCell being activated belongs to different frequency bands FR1 / FR2 and whether the SCell being activated is known or unknown, it can be divided into the following situations: Situation 1: The SCell being activated belongs to FR1 but is an unknown SCell; Situation 2: The SCell belongs to FR1 but is known; Situation 3: The SCell belongs to FR2 but there is at least one active serving cell in this FR2 band; Situation 4: The SCell belongs to FR2 but there is no active serving cell in this FR2 band. However, for all situations, after the NES UE receives the SCell activation instruction in slot n, the activated SCell performs valid CQI reporting no later than the slot.

[0543] For Scenario 5: Activation of a known NES SCell based on measurements for quickly deactivating the NES SCell

[0544] The purpose of defining known conditions is to define the prerequisites for an activated cell to become a known cell.

[0545] How to define a known cell:

[0546] 1) Report valid results within Xs

[0547] 1: The UE uses the adapted SSB measurement resources to perform measurements and report a valid L3 measurement result (either the first or the latest) accompanied by SSB index information.

[0548] A. This valid measurement result was reported within X seconds prior to receiving the NES SCell activation command.

[0549] The SSB resource cycle and DRX cycle configuration after BX adapts to SSB are related. As an example, for FR1, it can be X = Max(5*T_(SSB_NES), 5*DRXcycle).

[0550] 2: Within X s, according to the cell identification criteria, the NES SCell is detectable. Taking FR1 SCell cell as an example, if the above 1 and 2 are satisfied, the NES SCell becomes a known cell; otherwise, it is an unknown cell.

[0551] If the known conditions are met, how to activate the corresponding NES SCell within a very short delay depends on when the SSB adaptation deactivation instruction is received.

[0552] Scenario 1: For cases where an SSB adaptation deactivation instruction is received before the NES SCell activation instruction is received. In this case, the corresponding NES SCell will be activated based on the pre-adaptation SSB resources with a default (e.g., sparse) period.

[0553] (Challenge: Given that the condition definition and NES SCell activation use different SSB resources)

[0554] For two resources with different temporal locations of SSBs (e.g., different locations and / or positions), for example, the location of an SSB may involve the offset of the system frame number (SFN) and / or half-frame index corresponding to the SSB, and the position of an SSB may involve the location of the SSB within an SSB burst.

[0555] Negative impact: Existing known cell activation delays cannot cover the additional delays including SFN detection and TCI selection, which can lead to SCell activation failure or mishap.

[0556] Solution: Define applicability conditions: To ensure that timing, coarse AGC, and Tx beam information available from the adapted SSB resources can be reused in NES SCell activation with known traditional SSBs, the following assumptions need to be considered:

[0557] A. The frequency position of SSB resources is the same before and after SSB adaptation.

[0558] B. The spatial location of SSB resources is the same before and after SSB adaptation.

[0559] C. The temporal location of SSBs in the SSB burst sets within the first and second half-frames of SSB adaptation is the same.

[0560] D. SSB bias is the same before and after SSB adaptation.

[0561] If the above conditions are met, cell detection and coarse AGC settings on the target NES Scell ​​can be skipped, and the known NES Scell ​​can be activated according to the existing timeline based on the existing timeline, using the previously adapted SSB resources.

[0562] Case 2: In the next deactivation of Scell ​​state, an SSB adaptation deactivation instruction is received after the Scell ​​deactivation instruction.

[0563] For FR1 cell activation in case 1 (i.e., receiving the SSB adaptation deactivation indication instruction before receiving the NES SCell activation instruction), it can include the following two cases (the case after the cell becomes a known cell, referred to as known case 1 and known case 2 respectively):

[0564] Given case 1: T activation_time =T T / Ftrancking +5ms (<=X1)

[0565] Given case 2: T activation_time =T FineAGC +T t / Ftrancking +5ms (otherwise)

[0566] Case 1 and Case 2 depend on whether the measurement cycle of the SCell to be activated is less than or equal to X1. X1 is related to the measurement cycle and can be 2400ms.

[0567] Where T T / Ftrancking For time / frequency tracking based on traditional SSB; T FineAGC This refers to the precise AGC synchronization time based on the traditional SSB.

[0568] For FR1 cell activation in scenario 2 (i.e., receiving the SSB adaptive deactivation instruction after the Scell ​​deactivation instruction in the next deactivation Scell ​​state):

[0569] Based on the adapted SSB dense cycle, perform corresponding SCell activation (activation time or activation delay is T). activation_time_NES ), where T T / Ftrancking Transform into T T / Ftrancking_NES The time to complete T / F tracking on the target NES SCell is related to the time to receive the first complete SSB burst for adaptation used in T / F tracking.

[0570] T FineAGG Transform into T FineAGC_NES The time to complete fine AGC on the target NES SCell is related to the time to receive the first full SSB burst for adaptation to fine AGC, where:

[0571] Assume there are no active FR2 serving cells supporting SSB adaptation within the frequency band of this SCell, and that the NES SCell is the first unknown SCell to be activated; and

[0572] T firstSSB_NES <SMTC period

[0573] thus,

[0574] Given case 1: T activation_time =T T / Ftrancking_NES +5ms

[0575] Given case 2: T activation_time =T Fine AGC_NES +T T / F trancking_NES +5ms

[0576] All parameters are based on the adapted SSB resources. The changes are as follows: Configuration As shown

[0577] Among them, T firstSSB_NES This indicates the first possible time when SSB_NES can be received.

[0578] T activation_time_NES SCell activation delay for NES or NES only.

[0579] Specifically, based on the above main parameters, and depending on the configuration of different adaptive resources, the activation timeline for unknown cells can vary (when the SCell belongs to FR1 and is unknown).

[0580] Activation of unknown cells can be achieved by using AGC, cell detection, L1 measurement, and time / frequency tracking based on the adapted SSB resources with a short period of time, in order to reduce activation latency.

[0581] Beneficial effects: Using adaptive SSB resources for cell activation can reduce latency by tens of milliseconds, especially when a long SMTC period is configured, enabling fast scheduling of SCells.

[0582] A. If activation is based on only one SSB configuration, and the only difference between the SSBs before and after adaptation is their cycle time.

[0583] The UE can achieve accelerated activation latency T by using only adaptive SSB resources to perform secondary cell activation. activation_time .

[0584] Accelerate T activation_time From 6ms + 24 * SMTC period + T L1-RSRP,measure +T L1-RSRP,report +T HARQ +max(T uncertainty_MAC +SMTC period +2ms,T uncertainty_SP )arrive

[0585] Item 1 and Item 2 Cell detection / cell synchronization acquisition time + AGC adjustment time: changed from the SMTC cycle to the adapted SSB cycle. Where T... FirstSSB_NES_MAX This is the cycle after SSB adaptation;

[0586] Item 3 (Precise Synchronization T) Finetiming_NES (i.e., T / F tracking is performed on the target NES SCell): This is a fine time synchronization adjustment based on adaptive SSB. The SMTC cycle changes to a compact cycle T adapted to SSB. SSB_NES ;

[0587] Assumptions: No FR2 serving cell is activated to support SSB adaptation; SCell is measured using adapted SSB.

[0588] Item 4 (T) L1-RSRP_Measurement_Period_SSB_NES ): The time / delay of L1 measurement depends on the NES-specific measurement sample interval and the measurement priority associated with DRX:

[0589] 1) Time interval between two SSBs: determined by T SSB Become a compact T SSB_NES

[0590] 2) Measurement priority related to DRX: Once SSB adaptation is triggered, the most important task is for the UE to complete L1 measurement and transmit beam selection as soon as possible.

[0591] Layer 1 measurements in non-DRX mode can be prioritized, or even with DRX configuration, measurements can be performed in intensive cycles after SSB adaptation.

[0592] Combined with T SSB_NES The measurement priorities associated with DRX, and the L1-RSRP measurement cycle adapted to SSB resources, can be defined as shown in Table 10:

[0593] Table 10 Measurement Period T L1-RSRP_Measurement_Period_SSB_NES for FR2

[0594] non-DRX T L1-RSRP_Measurement_Period_SSB_NES (ms) DRX cycle > 320 ms max(T Report ,ceil(M*P*N)*T SSBNES )]]> Figure 18 ceil(1.5*M*P*N)*T DRX ]]>

[0595] B. If based on two SSB configurations, and these two SSBs have different frequencies and periods, and both require measurement.

[0596] Accelerate T activation_time : 6ms + 24 * SMTC period + T L1-RSRP,measure +T L1-RSRP,report +T HARQ +max(T uncertainty_MAC +SMTC period +2ms,T uncertainty_SP ) becomes 6ms+T FirstSSB_NES_MAX +15*T SSB_NES +8*T rs_NES +T L1-RSRP_Measurement_Period_SSB_NES +T L1-RSRP,report +T HARQ +max(T uncertainty_MAC +T Finetiming_NES +2ms,T uncertainty_SP )

[0597] Item 1:

[0598] How to accelerate AGC: If the first complete SSBs of two resources are not aligned on the same time slot, the activation time should be based on the first common SSB of all resources in the same frequency band.

[0599] T FirstSSB_NES_MAX +15*T SSB_NES T FirstSSB_NES_MAX For max(T) FirstSSB_default SSB resource ,T FirstSSB_second SSB resource )

[0600] Among them, T FirstSSB_default SSB resource Indicates the default SSB resource lifecycle, T FirstSSB_second SSB resource T represents the second SSB resource cycle. FirstSSB_default SSB resource and T FirstSSB_second SSB resource This indicates adaptation to the two SSB cycles before and after.

[0601] How to speed up cell detection: Two SSBs in the same SCell have the same half-frame.

[0602] UEs can flexibly utilize default or NES-specific resources with tight cycles for cell detection.

[0603] 8*T rs_NES ,T rs_NES Corresponding to min(T) default SSB resource ,T second SSB resource )

[0604] Otherwise: Obtain coarse timing for SCell based on SSB default resources.

[0605] Item 2: AGC Adjustment

[0606] (Challenge exists: the initial values ​​of the first complete SSB corresponding to the two resources are not aligned in the same time slot)

[0607] Existing method limitations: Within the FR1 band, when multiple SCells are active, the AGC time is determined by the longest AGC set time.

[0608] Activation delay requires the first shared SSB of the two SSB resources, defined as T. FirstSSB_NES_MAX

[0609] At this time, T AGC_NES～ T FirstSSB_NES_MAX In this context, “~” means “related to…”.

[0610] As one possibility:

[0611] AGC can adjust or set the time to T. FirstSSB_NES_MAX =operator4(T SMTC_MAX_NES SSB ,T SMTC_MAX ,T SSB_NES (where operator 4 can be one of, min, or max).

[0612] Item 3: Obtain precise T / F tracking

[0613] The UE can flexibly use the default or NES compact period SSB resources for precise T / F tracking, and use the same SSB resources as those used for cell detection.

[0614] T Finetiming_NES ~min(T Finetiming_default SSB resource ,T Finetiming_additional SSB resource )

[0615] Item 4: L1 Measurement. The UE flexibly uses either the default or NES compact periodic SSB resources for L1 measurement.

[0616] L1-RSRP_Measurement_Period_SSB_NES:max(T Report ,ceil(M=1*P*N)*T SSB_NES ),T SSB_NES =min(T) default SSB resource ,T second SSB resource )

[0617] Combining items 1-4, the timeline for an unknown single NES cell can be defined as:

[0618] T unknown NES SCell activation_time ~T rs_NES +T AGC_NES +T Finetiming_NES +T L1- RSRP_Measurement_Period_SSB_NES

[0619] C. The UE executes items 1, 2, and 3 based solely on either the first default SSB or the second NES-dedicated SSB resource, depending on which is faster (shorter cycle).

[0620] T FirstSSB_NES_MAX The duration of the first SSB adaptation resource indicated by the measurement timing configuration. This measurement timing configuration can be SMTC_NES or the original SMTC, and the SSB can be an adaptable / adaptive SSB (SSB_NES) that can be received by the NES UE or a traditional SSB. If both types of SSBs exist, the NES-enabled UE can define measurement rules based on its implementation; for example, to obtain NW power-saving gain, the NES UE can preferentially receive and measure SSB_NES. In this case, T... FirstSSB_NES_MAX This can be represented as the duration of the first SSB_NES of the measurement timing configuration indication;

[0621] 1) If the adaptable / adaptable SSB cycle is less than 5ms and / or greater than 160ms, or if the adaptable / adaptable SSB mode is the same as the traditional SSB, T FirstSSB_NES_MAX It can be the end time of the first SSB_NES burst indicated by the measurement timing configuration SMTC;

[0622] 2) If it can adapt to / adapts to SSB cycles less than 5ms and / or greater than 160ms, or if the mode of adapting to / adapting to SSB is different from that of traditional SSB, T FirstSSB_NES_MAX It can be the end time of the first SSB_NES burst indicated by the measurement timing configuration SMTC_NES.

[0623] When the active SCell is not fully known, and the target cell is not fully known and half a frame time needs to be obtained through MIB reading, the total duration of PSS / SSS cell detection and MIB reading for the UE is T. A =operator4(T SMTC_MAX_NES SSB ,T SMTC_MAX ,T SSB_NES Where operator 4 can be one of, min, or max.

[0624] - The original SMTC cycle range can include adaptable / adaptable SSB cycles;

[0625] - The SMTC configuration for the serving cell can be configured as either a long cycle or a normal cycle.

[0626] Among them, T SMTC_MAX_NES SSB In cases where cell-specific reference signals are provided for PSS / SSS timing capture and MIB reading for NES UEs, there is a longer SMTC period between the active serving cell and the active SCell.

[0627] T uncertainty_MAC_NES : Indicates the indeterminate time related to the UE receiving the MAC CE activation command.

[0628] For example, for a known cell scenario, the duration from when the NES UE receives the SCell activation command to when it receives the last activation command. The activation command may include at least one of the following: an activation instruction for PDCCH TCI, an activation instruction for PDSCH TCI, a semi-persistent CSI-RS activation instruction for CQI reporting, a SCell activation instruction, or an SSB time-domain adaptable / adaptive transmission instruction.

[0629] If the NES UE can receive all the above commands simultaneously, then T uncertainty_MAC_NES =0;

[0630] If the NES UE cannot simultaneously receive the SCell activation command and the SSB time-domain adaptable / adaptive transmission command, then T uncertainty_MAC_NES =U1, where U1 is a non-zero value, which can be an NW configuration or a fixed value. If the NES UE cannot receive at least two of the above instructions simultaneously, then T uncertainty_MAC_NES It can be a configured or predefined value, which can be related to the types of instructions that cannot be received simultaneously.

[0631] T uncertainty_transitionIt can adapt to the mode switching time between SSB transmission and traditional SSB transmission, or the switching time between NES mode and normal mode. This time can be a fixed value specified by the standard, or T. B =operator5(T SMTC_NES ,T SMTC ,T SSB_NES Operator5 can be min or one of.

[0632] T L1-RSRP,report_NES L1-RSRP measurement reporting time based on adaptive / adaptive SSB;

[0633] T HARQ : Automatic repeat request response time;

[0634] T uncertainty_SP The duration for receiving activation commands for the semi-persistent CSI-RS resource set used for CQI reporting;

[0635] T uncertainty_RRC The duration for receiving the RRC configuration message for the TCI of the periodic CSI-RS used for CQI reporting;

[0636] T RRC_delay :RRC processing delay;

[0637] Among them, T activation_time_NES Duration shorter than T activation_time This allows NESUE to quickly report valid CQIs, thereby rapidly activating the SCell and enabling transmission on that SCell. After quickly completing the data transmission, NW can enter sleep mode, thus achieving network power saving.

[0638] In one implementation, the known conditions of NES cells are divided into same-frequency and different-frequency identification. The known conditions of NES cells are defined as follows, taking same-frequency cells as an example:

[0639] T identify_intra_without_index_NES =(T PSS / SSS_sync_intra_NES +T SSB_measurement_period_intra_NES )ms or

[0640] T identify_intra_with_index_NES =(T PSS / SSS_sync_intra_NES +T SSB_measurement_period_intra_NES +

[0641] T SSB_time_index_intra_NES )ms

[0642] T identify_intra_without_index_NES NES cell identification time when SSB index detection is not required;

[0643] T PSS / SSS_sync_intra_NES : Duration / cycle of PSS / SSS detection for NES cells;

[0644] T SSB_time_index_intra_NES : Duration of SSB index detection for NES cells;

[0645] T SSB_measurement_period_intra_NES Measurement cycle for SSB-based measurements in NES cells

[0646] The improved cell PSS / SSS detection and time index detection are shown in Table 7-8 below, taking FR2 as an example:

[0647] Table 7 shows the SSB measurement period for the frequency-interval measurement (FR2) of the NES, without considering the measurement gap.

[0648]

[0649] Among them, M meas_period_w / o_gaps This indicates the total number of samples measured.

[0650] Table 8 shows the SSB measurement period for in-frequency measurements (FR2) of the NES, taking into account the measurement interval.

[0651]

[0652] The operator can be max, oneof, or min.

[0653] Where X can be a positive integer and can be preset. MGRP represents the measurement interval period.

[0654] In one implementation, the UE can report measurement results.

[0655] If in the shortened T SSB_measurement_period_intra_NES During this period, the signal-to-noise ratio related conditions are met. The UE should be able to trigger an L3 report based on the activated adaptive measurement resources.

[0656] Because the measurement here is a multi-sample measurement, if both traditional SSB and adaptive / adaptive SSB exist, the measurement results need to be averaged using rules, as described above.

[0657] After RF warm-up, AGC adjustment, receiving reference signals for cell detection, time index detection, measurement, and time synchronization, the UE measures the CQI and reports the first valid CQI, thus completing the cell activation process.

[0658] Step 6: The NW schedules the activated Scell ​​and performs data reception and normal L1 / L3 measurement tasks on the serving Scell. If the NES UE receives an adaptive / adaptive SSB indication activation command during this stage, the NES UE performs measurements based on SSBs of different periods.

[0659] When performing measurements on an already activated SCell, the measurement cycle, in cases involving conversion, can involve the following aspects:

[0660] 1. If SSB adaptation occurs within a measurement cycle, the larger value of the measurement cycle before and after the conversion can be considered.

[0661] For example, a transition occurs when, within a measurement period, an RRM measurement transitions from a measurement based on an SSB / SMTC resource configuration to a measurement based on an adaptive SSB / SMTC resource configuration, or vice versa (e.g., an RRM measurement transitions from a measurement based on an adaptive SSB / SMTC resource configuration to a measurement based on an SSB / SMTC resource configuration). In such cases, the measurement period is determined to be the longer measurement delay before and after the transition (or the measurement period itself). For example, the measurement period might be:

[0662] Ttransition = max{measurement period of the first mode, measurement period of the second mode}, where the first mode and the second mode are the SSB-related modes involved before and after the conversion, respectively. For example, the first mode is the traditional SSB mode or the normal mode, and the second mode is the adaptive SSB mode or the network energy saving (NES) mode.

[0663] 2. Measurements in Ttransition can be performed using one of the following methods to ensure appropriate sample selection and measurement accuracy:

[0664] Method 1: NES-capable UEs can measure two measurement resources with different periods, but the UE only reports one of them, such as the best and / or valid L3 measurement result among the results measured on the two measurement resources.

[0665] For example, if conventional measurement resources exist (e.g., conventional SSB-related measurement resources), the UE measures the conventional resources within one cycle and the adaptive resources (e.g., adaptive SSB-related measurement resources) after the entire measurement cycle unit. If the conventional measurement resources and the adaptive resources are time-division multiplexed (TDM), the UE can perform measurements according to the time-division method of the resources.

[0666] Method 2: Based on the NES scenario, prioritize measuring adaptive resources.

[0667] For example, after the transition period, the UE measurement has the highest priority adaptive measurement resources and performs X sample L1 measurement filtering (where X is a positive integer). Whether to release the measurement results based on traditional resources depends on the UE implementation.

[0668] Method 3: NES-capable UEs can measure resources in different periods and combine the measurement results, based on the premise that SSB resources are transmitted at the same frequency location.

[0669] The measurement result can be defined as follows:

[0670]

[0671] Among them, |SS-RSRP k | represents the measurement result of the k-th L1 sample before conversion;

[0672] |NES_SS-RSRP m | represents the measurement result of the m-th L1 sample after conversion;

[0673] c = 0 / 1 is an indicator, indicating whether to combine the measurement results before and after the transformation. For example, c = 0 means not to combine the measurement results before and after the transformation, c = 1 means to combine the measurement results before and after the transformation, and vice versa. S represents the total number of samples to be averaged. For example, if c = 0, S = M, otherwise, S = K + M, and vice versa.

[0674] In one implementation, if SSB adaptation occurs before or after a full measurement cycle, the UE prioritizes using adaptation resources for measurement.

[0675] For example, after the measurement period at the transition point, the UE performs measurements based on adapted resources (e.g., adapted second SMTC resources, or NES_SMTC resources, or additional SMTC resources) and flexibly reports the measurement results within the measurement period.

[0676] How to define the measurement cycle based on SSB adaptive measurement resources depends on the measurement resource cycle after adaptation, the scaling factor of time-domain conflicts of different measurement resources, and the NES CSSF and DRX cycle configurations.

[0677] Regarding cycles:

[0678] Scenario 1: If adaptation is based on an SSB configuration, and adaptation only occurs during the SSB cycle:

[0679] A dedicated SMTC cycle for NES: T SMTC_NES or T SSB_NES (T SMTC_NES<SMTC cycle); Case 2: If the adaptation is based on two SSB configurations and at most two configurations are activated:

[0680] (SMTC cycle, T SMTC_NES ) For the operator, the shortest cycle between the two can be selected, or one of the cycles between the two can be selected.

[0681] Regarding the scaling factor when different SSB measurement resources overlap in the time domain α：

[0682] In addition, when the SSB period and mode (e.g., the mode includes an energy-saving mode or a non-energy-saving mode) are adapted, SSB resource overlap occurs in the time domain.

[0683] Possible reasons for the overlap between the default measurement resources and the additional measurement resources used for adaptation on the same frequency that overlaps in the time domain: different offsets, compressed SSB

[0684] At this time, regarding which SMTC resource to use and whether to define α It can be one of the following:

[0685] 1) Always select the traditional SMTC (SMTC before conversion), without α ;

[0686] 2) The NES-specific SMTC has the highest priority, without α ;

[0687] 3) Based on the scenario, the UE flexibly selects the traditional SMTC or the NES-specific SMTC;

[0688] 4) If two resources need to be measured, the measurement period is relaxed by introducing a scaling factor α.

[0689] Regarding the NES carrier-specific scaling factor CSSF NES (The frequency positions before and after SSB adaptation are different): In addition, if the frequency position relationship before and after SSB adaptation changes, the NES carrier-specific scaling factor CSSF can be introduced NES , to determine the measurement period.

[0690] NES carrier-specific scaling factor: CSSF NES = 1 when the number of configured SCell (i.e., NES SCell) = 1 or for the NES SCC with the highest priority (if frequency-interval MO is configured for this SCC); otherwise, CSSF NES=CSSFintra, or =CSSFintraNES, based on the assumption that all SCCs, including NES SCCs, share a single...

[0691] For example, combined with T SMTC_NES , scaling factor α, CSSF NES Furthermore, considering the measurement gap MG and without considering the measurement gap, the corresponding intra-frequency measurement period can be defined according to Table 7 and Table 8, respectively.

[0692] For location 2, multiple cells are activated, such as... Figure 21 As shown,

[0693] Assumptions: The multiple deactivated secondary cells are NES cells, and only the period changes before and after adaptation.

[0694] The activation time for multiple cells is:

[0695] T activation_time_multi_NESCells =T activate_basic_multi_NESCells +N×T rs +T ED

[0696] T ED Due to the additional latency spread caused to the terminal in the same frequency band

[0697] Challenge: The exact location of the interruption is unknown. Activation of the SCell is suspected to cause loss of RS reception, and the NESSCell cannot be activated.

[0698] Solution: In multi-SCell active scenarios, consider delay extension to ensure sufficient allowable resources for AGC, cell detection, and T / F tracking.

[0699] Principle: Depending on where the interruption occurs during SCell activation, it is necessary to wait for the next permissible measurement of SSB resources.

[0700] If the interruption occurs during AGC setup using SSB:

[0701] T ED Waiting for 1 extra T FirstNES_SSB_MAX_multiple_scells for AGC setting

[0702] If the interruption occurs during cell synchronization using SSB or T / F tracking:

[0703] T ED Waiting for 1 extra T FirstNES_SSBfor cell synchronization or T / F tracking where T FirstNES_SSB_MAX_multiple_scells and T FirstNES_SSB Related to the dense cycle of adaptive SSB

[0704] N×T rs The cell detection delay is caused by all unknown cells sharing a single searcher constraint, where N is the number of unknown cells that have been activated.

[0705] Principle: Since all unknown cells share a single searcher, but cell detection is a time-series process, delay spread must take N into account.

[0706] Therefore, T activate_basic_multi_NESCells Cell activation delay based on SSB adaptation dense SSB cycle, depending on different adaptive SSB mechanisms. It is related to the following three parameters: T FirstNES_SSB_MAX_multiple_scells T NES_SSB_MAX_multiple_scells T L1- RSRP_Measurement_Period_SSB_NES

[0707] T FirstNES_SSB_MAX_multiple_scell For the time to reach the first complete adaptive SSB burst set,

[0708] T NES_SSB_MAX_multiple_scells The longest SSB cycle among multiple SCells, or the SSB cycle of the SCell to be activated.

[0709] AGC settings should be based on the maximum NES SSB cycle, not the maximum SMTC cycle, and L1-RSRP should also be based on the NES SSB cycle.
