The principles and embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. First, refer to... Figure 1A This illustrates an example communication system 100 in which embodiments of the present disclosure can be implemented. For example... Figure 1A As shown, environment 100, which may be part of a communication network, includes terminal device 110 and network device 120. Network device 120 may be a gNB, network (NW), or TRP that schedules a first bandwidth portion (BWP) or a first cell 130. As long as terminal device 110 is located within the corresponding cell (e.g., the first cell 130) of network device 120, terminal device 110 can connect and communicate with network device 120 in UL or DL.

[0042] Layer 1 or Layer 2 (L1 / 2) triggered mobility (LTM) or lower-layer mobility is a cell handover process in which the UE's serving cell (primary cell (PCell) or secondary cell (PSCell)) is switched by the network that sent the LTM cell handover command. The LTM cell handover command is currently assumed to be delivered via Medium Access Control (MAC) signaling using a MAC control element (CE), rather than using Radio Resource Control (RRC) signaling as in traditional Layer 3 (L3) based handover methods.

[0043] LTM cell handover decisions can be based on Layer 1 (L1) measurements, which are performed and reported by the UE using L1 measurement reports. These measurements and reports are based on the LTM candidate cell configuration provided by the network for one or more LTM candidate cells. LTM candidate cells can be neighboring cells or the UE's current serving cell (e.g., secondary cell (SCell)).

[0044] In version 18, synchronization signal blocks (SSBs) transmitted by candidate cells are used to perform LTM measurements for neighboring candidate cells. The UE uses the SSB configuration provided by the network to perform these measurements.

[0045] Prior to cell handover, the network may optionally activate one or more Transport Configuration Indicator (TCI) states for one or more candidate cells. Once a candidate cell TCI state is activated, the UE can begin tracking time / frequency synchronization using reference signals associated with the activated TCI state(s). Additionally, the UE may perform early uplink (UL) synchronization prior to cell handover if requested by the network.

[0046] Figure 1B Example signaling diagrams of an LTM procedure 140 associated with some embodiments of this disclosure are illustrated. It should be understood that the LTM procedure 140 is merely an example of a lower-layer triggered mobility implementation.

[0047] like Figure 1B As shown in the diagram, at point 141, the UE in RRC connection state sends a MeasurementReport message to the gNB. The gNB decides to configure LTM and initiates LTM preparation. At point 142, the gNB transmits to the UE a list of LTM candidate configurations. RRCReconfiguration (RRC reconfiguration) message. At position 143, the UE stores the LTM candidate configuration and transmits it to the gNB. RRCReconfigurationComplete (RRC reconfiguration complete) message.

[0048] At 144a, the UE performs downlink (DL) synchronization with the candidate cells(s) before receiving the cell handover command. At 144b, as specified in Technical Specification (TS) 38.300, before receiving the cell handover command, the UE performs early timing advance (TA) acquisition with the candidate cells(s) at the request of the network. This is accomplished via contention-free random access (CFRA) triggered by a physical downlink control channel (PDCCH) instruction from the source cell, after which the UE transmits a preamble to the indicated candidate cell. To minimize data interruption at the source cell due to CFRA toward the candidate cells(s), the UE does not receive a random access response from the network for the purpose of TA value acquisition. Instead, the TA value of the candidate cell is indicated in the cell handover command. The UE does not maintain a TA timer for the candidate cells and relies on the network implementation to ensure TA validity.

[0049] At 145, the UE performs L1 measurements on the configured candidate cells(s) and transmits an L1 measurement report to the gNB. L1 measurements should be performed whenever the RRC reconfiguration (in step 142) is applicable. At 146, the gNB decides to perform a cell handover to the target cell and transmits a MAC CE that triggers the handover, including a candidate configuration index for the target cell. The UE hands over to the target cell and applies the configuration indicated by the candidate configuration index. At 147, if the UE does not have a valid TA for the target cell, the UE performs a random access procedure toward the target cell as specified in TS 38.321.

[0050] At point 148, the UE sends a message to the target cell. RRCReconfigurationComplete The LTM cell handover process is completed with an "RRC reconfiguration complete" message. If the UE performed a random access procedure in step 7, it considers the LTM cell handover to be successfully completed when the random access procedure is successfully completed. For LTM without a random access channel (RACH), the UE considers the LTM cell handover to be successfully completed when it determines that the network has successfully received its first uplink (UL) data.

[0051] Steps 144 to 148 can be executed multiple times for subsequent LTMs using the LTM candidate configurations provided in step 142. The procedure 140 on the aforementioned air interface applies to both gNB-DU LTMs and gNB-DU LTMs. The overall LTM procedure on the F1 control (F1-C) interface is recorded in TS 38.401.

[0052] In Release 18 (R18) LTM, the network provides the UE with information about measurement resources (e.g., SSBs) from LTM candidate cells, enabling the UE to perform measurements. Additionally, the UE can be configured with an L1 measurement reporting configuration, allowing the UE to report measurements.

[0053] For LTM, the following reporting modes are supported: periodic and semi-persistent reporting on the Physical Uplink Control Channel (PUCCH); semi-persistent reporting on the Physical Uplink Shared Channel (PUSCH); and non-periodic reporting on the PUSCH.

[0054] The UE can be configured with one or more LTM CSI reporting configurations ( LTM-CSI-ReportConfig Each LTMCSI report configuration includes an LTM CSI resource configuration (). LTM-CSI-ResourceConfig This specifies the resources used for channel measurements, such as L1 Reference Signal Received Power (RSRP) measurements. For each LTM CSI reporting configuration, the UE can be instructed to report measurements for M beams for each candidate cell from L configured candidate cells. Specifically, each LTM-CSI- ResourceConfig Including the LTM-CSI SSB resource set (i.e., LTM-CSI-SSB-ResourceSet Configuration of ). LTM- CSI-SSB-ResourceSet Includes a list of Z SS / PBCH block indices (by...) ltm-CSI-SSB-ResourceList (The resource list is provided by ltm-CSI-SSB) and Z items. LTM-CandidateId The list (by) LTM-CandidateIdList (The LTM-candidate ID list is given), which corresponds to the candidate cells associated with the specified SS / PBCH block index, where Z≥1. Figure 1C Examples of LTM CSI reporting configurations associated with some embodiments of this disclosure are illustrated.

[0055] For each candidate cell, the UE is based on ssb-Periodicity and ssb-PositionsInBurst Parameters determine the temporal behavior of SS / PBCH block resources. Based on higher-level parameters. subCarrierSpacing , ssbFrequency To determine the frequency domain behavior of SS / PBCH block resources.

[0056] For each cell, an LTM CSI report configuration is provided under the current serving cell configuration. Each report configuration includes an LTM CSI resource configuration ( LTM-CSI-ResourceConfig Instructions and other report-related parameters, such as timing and uplink resources used for transmitting reports. LTM-CSI-ResourceConfig This can include a set of SSB indices from multiple candidate cells. These configurations are in the public LTM configuration ( LTM-ConfigDefined in ). Figure 1D Example diagrams illustrating the main components of an LTM configuration associated with some embodiments of this disclosure.

[0057] In LTM candidate information element (IE) ( LTM-Candidate IE LTM SSB configuration within ) LTM-SSB- Config Provided in ) LTM-CSI-ResourceConfig The detailed configuration for each SSB of the candidate cell is indicated in the document.

[0058] For each candidate cell, LTM-Candidate IE It contains the necessary configuration and information required by the UE before cell handover, such as SSB information for LTM measurements. LTM-Candidate IE It also includes a list of non-zero power CSI reference signal (NZP-CSI-RS) resources used to activate the Transmission Configuration Indicator (TCI) state associated with the Tracking Reference Signal (TRS) (a type of CSI-RS). These CSI RS resources can also be used for LTM measurements. Additionally, LTM-Candidate IE Including RRC containers ( ServingCellConfig This provides all the configuration details required by the UE after cell handover to the candidate cell. In other words, LTM-Candidate IE within ServingCellConfig Includes the configuration details required for regular serving cell operations within the candidate cells.

[0067] Uplink control information (UCI) is used to carry L1 measurement reports in R18 LTM. In other words, L1 signaling is used to carry the measurements in the report. The format of the L1 measurement report is documented in Table 6.3.1.1.2-8 C of TS 38.212, as shown in Table 5 below.

[0068] Table 5. Mapping order of CSI fields for a report used in SSBRI / RSRP reporting for LTM

[0069] Enhancements are needed to facilitate UE-initiated / event-driven beam management in order to reduce overhead and / or latency by leveraging the unified TCI framework and existing CSI measurement and reporting configurations. These enhancements target FR2 (Frequency Range 2) and single / multiple transmit receiver point (sTRP) scenarios, addressing intra-cell and inter-cell beam management. For example, improvements are needed to the uplink (UL) signaling content and procedures for UE-initiated / event-driven beam reporting to enable fast beam switching. Enhancements to the UL signaling media / container, optimized for the event-driven nature of UL transmissions associated with beam reporting, are also required.

[0070] Compared to Layer 3-based mobility, the LTM mechanism can reduce handover latency and downtime. However, LTM has limitations that require enhancements in the following areas: support for event-triggered L1 measurement reporting, support for CSI-RS measurements for LTM procedures and enable CSI-RS-based beam management, and / or support for other necessary physical layer operations on candidate cells prior to LTM.

[0071] Regarding LTM measurement enhancements, it is proposed that event-triggered L1 measurements should be designed to support two main objectives: selecting candidate beams or cells for early synchronization, and identifying target beams or cells to initiate LTM cell handover procedures. These measurements should primarily rely on beam-level measurement results as a baseline for event assessment, while further research is needed to evaluate the applicability of cell-level measurements. Beam-specific quality based on the serving cell and candidate cells is proposed to support the following LTM events as LTM measurement events: - Event LTM2: The serving cell's beam becomes worse than the absolute threshold; - Event LTM3: The candidate cell's beam becomes superior to the serving cell's beam by an offset; - Event LTM4: The candidate cell's beam becomes better than the absolute threshold; - Event LTM5: The serving cell’s beam becomes worse than absolute threshold 1, and the candidate cell’s beam becomes better than another absolute threshold 2.

[0072] This paper proposes beam configurations that support both SSB and CSI RS in the L1 measurement resource configuration within an LTM configuration. It assumes that in events such as LTM3 and LTM5, the same reference signal type will be used for both the serving cell and neighboring cells. The paper also proposes the need to filter the L1 measurement results, and that the filtering can be normalized or left to the UE to implement.

[0073] Event assessment for LTM relies on parameters such as trigger time (TTT), hysteresis for entry or exit conditions, and beam-specific offset (or cell-specific offset).

[0074] Additionally, the following is proposed regarding L1 event-triggered Measurement Reports (MRs): Based on network configuration, MRs can be sent when departure conditions are met. Based on network configuration, event-triggered periodic MRs can be supported. For measurement resource configuration, R18 LTM CSI resource configurations are reused if possible. For measurement report configuration, R18 is reused if possible. LTM- CSI-ReportConfig For the correlation between measurement resource configuration and measurement report configuration, the R18LTM approach should be reused if possible.

[0075] The entire event assessment process can be handled by the MAC based on the latest L1 measurement reported by L1. TTT can operate solely based on a timer (e.g., the TTT used in an MR triggered by an L3 event). For events LTM3 and LTM5, the same reference signal type can be used for both the serving cell and neighboring cells.

[0076] The basic information included in the MR MAC CE may include: beam information (e.g., SSBRI or CRI of N beams), beam quality metrics (such as L1-RSRP or SINR), and information on triggering events (e.g., ReportConfigID The MR MAC CE format supports up to N beams, where N can be configured by the network. Additional information about the current beams and their number can also be included based on the network configuration. For resource allocation, the SR procedure used for resource allocation can be the baseline for transmitting event-triggered L1 measurement MAC CEs, although the dedicated SR configuration for MR MAC CE transmissions can be specified by the network.

[0077] Furthermore, the following is proposed regarding event-driven L1 MR: TTT is evaluated for each beam, and measurement reports are triggered only by beams whose conditions (entry / departure) have been met throughout the entire duration of the TTT. If the current beam changes but the entry condition remains met in the case of the new beam, the TTT timer is not restarted. Additionally, the TTT mechanism also applies to departure conditions.

[0078] The network can be configured to use which reference signal type (such as SSB or CSI-RS) for LTM event assessment. CSI-RS or SSB can be configured as candidate beams, and the measurement reference signal for the serving cell beam is selected based on these candidate beams. This configuration ensures that the reference signal type for the serving cell reference signal (beam) is the same as or quasi-co-located (QCLed) for the QCL reference signal of the indicated TCI state.

[0079] Candidate beam IDs in LTM MR MAC CE are represented using SSB Resource Indicators (SSBRI) and CSI RS Resource Indicators (CRI). The maximum number N of beams, N, included in an event-triggered L1LTM measurement report can be configured by the network. The network also controls whether beams that do not meet the event conditions can be reported based on the N beams included in the MR MAC CE.

[0080] A single MACCE format is proposed for event-triggered L1 measurement reports applicable to both SSB and CSI RS reference signals. Furthermore, support for truncated measurement reports is also proposed.

[0081] In some implementations, the MAC CE can be used as a reporting medium / container for event-triggered measurement results. An event-triggered report can be triggered when at least one LTM candidate cell reference signal (i.e., candidate reference signal ID, candidate beam ID) meets reporting criteria (such as LTM3) during the TTT duration. When the TTT expires and the candidate reference signal has met the criteria during the TTT duration, an LTM MR MAC CE is triggered to transmit the candidate reference signal information to the network.

[0082] In some implementations, TTT can operate at the candidate reference signal level. That is, TTT can be used individually for each beam. Since event-triggered reporting is observed at the beam level, a UE can trigger multiple event-triggered reports at different time instances, for example, when TTTs for different beams in different cells do not expire at the same time instance. This can result in a UE subsequently triggering multiple MR MAC CEs or triggering MAC CEs that typically generate uplink load. Furthermore, there may be multiple UEs configured with event-triggered reporting in a cell, so the number of MAC CEs transmitted by a UE may be large, too frequent, or undesirable / network-dependent.

[0083] In some implementations, a disable timer can be used during the MAC layer process to limit the number of triggered MAC CEs. Some embodiments of this disclosure can provide solutions for disabling timer operation for LTM MR MAC CEs. Reference will be made below. Figures 2A to 3 The embodiments of this disclosure are described in detail.

[0084] Figure 2A A signaling diagram illustrating a first example process 200A according to some embodiments of this disclosure is provided. For discussion purposes, reference will be made to... Figure 1A Describe process 200 A. Process 200 A may involve terminal device 110 and network device 120. It should be understood that, although already... Figure 1A The process 200 A is described in the communication environment 100, but the process can also be applied to other communication scenarios.

[0085] like Figure 2A As shown, terminal device 110 determines (214) the occurrence of a triggering event associated with the reporting configuration. Terminal device 110 triggers (215) a measurement report associated with the reporting configuration based on the state of the timer associated with the reporting configuration. In this way, a timer for disabling the LTM for each event-triggered reporting configuration is applied for each reporting configuration or each event-triggered reporting configuration. This reduces resource overhead.

[0086] In some embodiments, if a reporting criterion is met within a first duration, the terminal device 110 can determine that a triggering event has occurred. The terminal device 110 can receive an indication of the first duration from the network device. The first duration can be implemented as a TTT (Time To Time), and the TTT duration or timer value is configured by the network in the reporting configuration.

[0087] In some embodiments, the reporting configuration can be associated with a cell handover process (e.g., an LTM process). The disable timer can be implemented as Tprohibit_LTM. The reporting configuration can be implemented as an LTM reporting configuration.

[0088] Alternatively or additionally, the report configuration can be associated with the beam management process. In other words, the prohibition timer can be implemented as Tprohibit_UEIBM and can be applied to UE-initiated or event-driven measurement reports for beam management, such as UEIBM reports or UE event-triggered beam management reports. The report configuration can be implemented as a UEIBM report configuration. The report can use a MAC CE as a report container. Although some specific embodiments (and naming) are described with respect to the LTM program, embodiments of the invention can also be applied to other programs that include UEIBM programs or other programs. In any embodiment herein, LTM MR MAC CE and UEIBM MR MAC CE can be used interchangeably.

[0089] In some embodiments, when a measurement report associated with a report configuration is triggered, the terminal device 110 may perform at least one of the following: triggering the generation of a measurement report; instructing a multiplexing and assembly process to generate and transmit the measurement report; determining that uplink authorization is available for transmitting the measurement report; or transmitting the measurement report. In an example implementation, triggering an LTM MR MAC CE may refer to one or more of the following: triggering the generation of an LTM MR MAC CE; instructing a multiplexing and assembly process for generating and transmitting the LTM MR MAC CE; or sending an LTM MR MAC CE.

[0090] In some embodiments, if a measurement report associated with a report configuration is triggered, the terminal device 110 may transmit (216) a measurement report 217 to the network device 120. Therefore, the network device 120 may receive (218) the measurement report 217 from the terminal device 110.

[0091] In some embodiments, the measurement report may be carried in an uplink control information (UCI) report. Alternatively or additionally, the measurement report may be carried in a media access control (MAC) control element (CE) report. In the example implementation, the measurement report may refer to a UCI report or a MAC CE report that reports event triggering information.

[0092] In some embodiments, the terminal device 110 may start a timer based on a triggered measurement report. In an example implementation, when the LTM MR MAC CE is triggered by an event configured for the report, the timer Tprohibit_LTM configured for the report is started.

[0093] In some embodiments, terminal device 110 may trigger a measurement report associated with a reporting configuration based on determining that a timer associated with the reporting configuration is not running or is in a non-running or expired state. In other words, terminal device 110 may trigger a measurement report associated with a reporting configuration if the timer associated with the reporting configuration is in a non-running or expired state when the triggering event occurs. In the example implementation, if no Tprohibit_LTM is running for the same reporting configuration when the triggering event occurs or the measurement report is triggered, the timer is prevented from starting. As used herein, the expiration state of a timer may refer to a timer that has expired or is already expired.

[0094] In some embodiments, if a timer associated with the reporting configuration (i.e., a disable timer) is running, the terminal device 110 may not trigger a measurement report associated with the reporting configuration. In other words, if a timer associated with the reporting configuration is running when a trigger event occurs, the terminal device 110 may not trigger a measurement report associated with the reporting configuration. In the example implementation, if a Tprohibit_LTM associated with the reporting configuration is running when at least one reference signal trigger event for the reporting configuration is triggered, a new LTM MRMAC CE for the same reporting configuration is not triggered.

[0095] In some embodiments, if a timer associated with the reporting configuration (i.e., a disable timer) is running when a trigger event occurs, the terminal device 110 can trigger a measurement report when the timer expires. In an example implementation, if Tprohibit_LTM is running when an event is triggered for at least one reference signal of the reporting configuration, then LTM MR MAC CE can be triggered for the reporting configuration when Tprohibit_LTM expires. That is, LTM MR MAC CE can be triggered for a reference signal that has expired or expired when Tprohibit_LTM expires, or has expired, or is not running.

[0096] In some embodiments, if a timer associated with the reporting configuration (i.e., a disable timer) is running when a trigger event occurs, terminal device 110 can determine whether the reporting criteria associated with the trigger event are met when the timer expires. If the reporting criteria are met when the timer expires, terminal device 110 can trigger a measurement report. If the reporting criteria are not met when the timer expires, terminal device 110 can not trigger a measurement report associated with the reporting configuration. In an example implementation, LTM MR MAC CE is triggered for a reference signal where TTT has expired and the reporting criteria are met when Tprohibit_LTM expires, has expired, or is not running. In another example implementation, LTM MR MAC CE is not triggered for a reference signal where TTT has expired and the reporting criteria are met when Tprohibit_LTM expires.

[0097] In some embodiments, network device 120 may transmit (211) report configuration and configuration information for timers associated with report configuration 212 to terminal device 110. Terminal device 110 may receive (213) report configuration and configuration information for timers (i.e., disable timers) associated with report configuration 212 from network device 120.

[0098] In some embodiments, terminal device 110 may receive from network device 120 a configuration for reporting measurements of mobility or cell handover associated with at least one reporting configuration including a reporting configuration. The configuration for reporting measurements of mobility or cell handover may include configuration information for at least one timer (i.e., a timer disablement) associated with the at least one reporting configuration. In an example implementation, the configuration and configuration value of Tprohibit_LTM may be included in the LTM reporting configuration according to each reporting configuration for event-triggered measurement reporting.

[0099] In some embodiments, Tprohibit_LTM can be applied to each reported cell. In some embodiments, Tprohibit_LTM can be applied to each reported event. In some examples, Tprohibit_LTM can be applied to each reported cell (and / or event), and the value is configured for each reported configuration. In some examples, Tprohibit_LTM can be applied to each reported cell (and / or each event), and the value is configured for each reported cell. As an example, when a report has already been triggered for one or more reference signals for one or more cells, and if Tprohibit_LTM is running, for the same reporting configuration, a new report may not be triggered for additional reference signals for the same(s) cells(s). As an example, when a report has already been triggered for one or more reference signals for one or more cells, and if Tprohibit_LTM is running, a new report may not be triggered for different events for the same reference signal (and / or for the same cell). As another example, when a report has already been triggered for one or more reference signals for one or more cells, and if Tprohibit_LTM is running, a new report may not be triggered for the same event in the same reporting configuration for additional reference signals for the same cells(s). A report may be triggered (as described herein) when Tprohibit_LTM expires and the reporting criteria are met.

[0100] In some embodiments, terminal device 110 may receive configurations from network device 120 for mobility or cell handover associated with at least one reporting configuration, including reporting configuration. The configuration for mobility or cell handover may include configuration information for at least one timer associated with the at least one reporting configuration. In an example implementation, the configuration and configuration value of Tprohibit_LTM may be separately included in the LTM configuration.

[0101] In some implementations, the configuration information for the at least one timer may include a timer value associated with the at least one reporting configuration. In an example implementation, a single value for Tprohibit_LTM can be configured for all reporting configurations. Alternatively or additionally, the configuration information for the at least one timer may include at least one timer value associated with the at least one reporting configuration. In an example implementation, a corresponding value for Tprohibit_LTM can be configured for different reporting configurations. Alternatively or additionally, the configuration information for the at least one timer may include at least one timer value associated with at least one event type of the event that triggers the measurement report. In an example implementation, the configuration and configuration value of Tprohibit_LTM can be configured by event type. Alternatively or additionally, the configuration information may include at least one timer value associated with a reporting configuration. In an example implementation, multiple values ​​for Tprohibit_LTM can be configured for a single reporting configuration.

[0102] In some embodiments, the timer value is associated with the event type that triggered the event. As an example, when the LTMx event triggers LTM MR MAC CE, the timer is prevented from starting with the timer value for the LTMx event.

[0103] In some embodiments, terminal device 110 may transmit to network device 120 an indication of its capability to support event-triggered measurement reports based on a disable timer. In some embodiments, terminal device 110 may transmit to network device 120 an indication of its capability to support event-triggered measurement reports based on a disable timer configured for each report. In an example implementation, terminal device 110 may indicate its capability to support event-triggered measurement reports configured for each LTM event.

[0104] In some embodiments, the capability indication may include the maximum number of timers that the terminal device supports running concurrently. In other words, the capability may indicate the maximum number of disabled timers that the terminal device can support concurrently. Alternatively or additionally, the capability may indicate the maximum number of disabled timers that the terminal device can support concurrently for each report configuration. Alternatively or additionally, the capability indication may include the maximum number of timers that the terminal device supports running concurrently on all report configurations. Alternatively or additionally, the capability indication may include the maximum number of report configurations with timers that the terminal device supports running concurrently. Alternatively or additionally, the capability may indicate the maximum number of disabled timers that the terminal device can support concurrently for each event type of report configuration. Alternatively or additionally, the capability may indicate the maximum number of disabled timers that the terminal device can support concurrently across all event types. Alternatively or additionally, the capability indication may include the maximum number of events with timers that the terminal device supports running concurrently.

[0105] In some embodiments, if a timer is running, the terminal device 110 may not transmit a request for resources for a measurement report associated with the report configuration. In an example implementation, during the UEIBM process, disabling the timer can be applied to request uplink resources to send uplink signals for event-triggered measurement reports.

[0106] Figure 2B A signaling diagram illustrating a second example process 200B according to some embodiments of this disclosure is provided. For discussion purposes, reference will be made to... Figure 1A Describe process 200 B. Process 200 B may involve terminal device 110 and network device 120. It should be understood that, although already described... Figure 1A The process 200 B is described in the communication environment 100, but the process can also be applied to other communication scenarios.

[0107] like Figure 2B As shown, terminal device 110 determines (224) the occurrence of a trigger event based on measurements of a reference signal or beam. Terminal device 110 triggers (225) a measurement report based on the state of a timer (i.e., a disable timer) associated with the reference signal or beam. In this way, a disable timer for the LTM used for event triggering is applied for each reference signal / beam associated with the event. For example, for events LTM3, LTM4, and LTM5, a separate disable timer is applied for each candidate reference signal / beam configured in association with the report configuration. For event LTM2, a separate disable timer is applied to the serving reference signal / beam. This reduces resource overhead.

[0108] In some embodiments, the timer may be associated with a reference signal or beam associated with the reporting configuration. In other words, a disable timer may be applied for each reference signal / beam associated with the reporting configuration. In one example embodiment, Tprohibit_LTM may be configured for a reference signal / beam associated with the reporting configuration.

[0109] In some embodiments, if a reporting criterion is met within a first duration, the terminal device 110 can determine that a triggering event has occurred. The terminal device 110 can receive an indication of the first duration from the network device. The first duration can be implemented as a duration or a timer value configured by the network for a TTT (Time To Time).

[0110] In some embodiments, the triggering event may be associated with a cell handover process (e.g., an LTM process). The disable timer may be implemented as Tprohibit_LTM. The candidate reference signal or beam may be implemented as an LTM candidate reference signal or beam. The candidate cell may be implemented as an LTM candidate cell.

[0111] Alternatively or additionally, the triggering event can be associated with the beam management procedure. In other words, the prohibition timer can be implemented as Tprohibit_UEIBM and can be applied to UE-initiated or event-driven measurement reports for beam management, such as UEIBM reports or UE event-triggered beam management reports. Candidate reference signals or beams can be implemented as UEIBM candidate reference signals or beams. Candidate cells can be implemented as UEIBM candidate cells. Although some specific embodiments are described with respect to the LTM procedure, embodiments of this disclosure can also be applied to other procedures that include UEIBM procedures or other procedures. In any embodiment herein, LTM MR MAC CE and UEIBM MR MAC CE can be used interchangeably.

[0112] In some embodiments, when a measurement report associated with a reference signal or beam is triggered, the terminal device 110 may perform at least one of the following: triggering the generation of a measurement report; instructing a multiplexing and assembly process to generate and transmit the measurement report; determining that uplink authorization is available for transmitting the measurement report; or transmitting the measurement report. In an example embodiment, triggering an LTM MR MACCE may refer to one or more of the following: triggering the generation of an LTM MR MACCE; instructing a multiplexing and assembly process for generating and transmitting an LTM MR MACCE; or sending an LTM MR MACCE.

[0113] In some embodiments, if a measurement report is triggered by a triggering event based on a measurement of a reference signal or beam, the terminal device 110 may transmit (226) a measurement report 227 to the network device 120. The measurement report 227 may include information about the reference signal or beam. Therefore, the network device 120 may receive (228) the measurement report 227 from the terminal device 110.

[0114] In some embodiments, the measurement report may be carried in the UCI report. Alternatively or additionally, the measurement report may be carried in the MACCE report. In the example implementation, the measurement report may refer to a UCI report or a MACCE report that reports event triggering information.

[0115] In some embodiments, terminal device 110 may start a timer based on a triggered measurement report. In an example implementation, when the LTM MR MAC CE is triggered by an event based on a measurement of a candidate or serving reference signal / beam, a prohibition timer Tprohibit_LTM for the candidate or serving reference signal / beam is started. In some examples, the serving cell reference signal may refer to a reference signal included in the indicated TCI state. The indicated TCI state may refer to a reference signal used as a reference for uplink and / or transmission of a signal and / or channel.

[0116] In some embodiments, network device 120 may transmit (221) configuration information 222 for a timer associated with a reference signal or beam to terminal device 110. Terminal device 110 may receive (223) configuration information 222 for a timer associated with a reference signal or beam from network device 120.

[0117] In some embodiments, terminal device 110 may receive configuration information for at least one timer associated with the at least one reference signal or beam from network device 120. In some embodiments, the configuration information for the at least one timer may include a timer value associated with the at least one reference signal or beam. In an example implementation, a single value of Tprohibit_LTM can be configured for all reference signals or beams. Alternatively or additionally, the configuration information for the at least one timer may include at least one timer value associated with the at least one reference signal or beam. In an example implementation, a corresponding value of Tprohibit_LTM can be configured for different reference signals or beams. Alternatively or additionally, the configuration information for the at least one timer may include at least one timer value associated with at least one event type of an event that triggers a measurement report. In an example implementation, the configuration and configuration value of Tprohibit_LTM can be configured by event type. Alternatively or additionally, the configuration information may include at least one timer value associated with the at least one reference signal or beam for each event type. Alternatively or additionally, the configuration information may include at least one timer value associated with a reference signal or beam. In the example implementation, multiple values ​​for Tprohibit_LTM can be configured for a reference signal or beam.

[0118] In some embodiments, terminal device 110 may trigger a measurement report based on determining that a timer associated with a reference signal or beam is in a non-running or expired state. In other words, if a timer associated with a reference signal or beam is in a non-running or expired state when a triggering event occurs, terminal device 110 may trigger a measurement report containing information about the reference signal or beam. In an example implementation, if the triggering event occurs based on a measurement of a candidate or serving reference signal or beam, and no Tprohibit_LTM is running for the same candidate or serving reference signal or beam, then the timer is prevented from starting. As used herein, the expiration state of a timer may refer to a state where the timer has expired or has already expired.

[0119] In some embodiments, if a timer associated with a reference signal or beam is running, terminal device 110 may not trigger a measurement report for the reference signal or beam. In other words, if a timer associated with a reference signal or beam is running when a trigger event occurs, terminal device 110 may not trigger a measurement report containing information about the reference signal or beam. In an example implementation, if a Tprohibit_LTM associated with a candidate reference signal or beam is running when a trigger event occurs for the candidate reference signal or beam, a new LTM MR MAC CE is not triggered for the same candidate reference signal or beam. In another example implementation, if a Tprohibit_LTM associated with a reference signal or beam is running, and when there is no trigger event for the reference signal or beam and an LTM MR MAC CE is triggered, the LTM MR MAC CE does not contain information about the reference signal or beam. In some embodiments, if a timer associated with a reference signal or beam is running and a measurement report is triggered, terminal device 110 may include information about the reference signal / beam in the measurement report. In other words, if the timer associated with the reference signal or beam is running and a measurement report is triggered, and when no event is triggered for the reference signal / beam, the terminal device 110 can include the information of the reference signal / beam in the measurement report.

[0120] In some embodiments, the timer is a first timer, i.e., a first disable timer, the reference signal or beam is a first reference signal or beam, and the measurement report may include information about the first reference signal or beam and information about the second reference signal or beam. If no triggering event based on a measurement of the second reference signal or beam occurs, the terminal device 110 may not start the second timer associated with the second reference signal or beam (i.e., the second disable timer). In one example implementation, when the LTM MR MAC CE is triggered by the first candidate reference signal / beam and sends information about the second candidate reference signal / beam containing an event / condition that does not meet the configuration, the disable timer is not started for the second candidate reference signal / beam. In other words, the disable timer is not started for a reference signal / beam that does not meet the configured event / condition.

[0121] In some embodiments, the timer is a first timer, the reference signal or beam is a first reference signal or beam, and the measurement report may include information about the first reference signal or beam and information about a second reference signal or beam. Terminal device 110 may start a second timer associated with the second reference signal or beam, regardless of whether a triggering event based on a measurement of the second reference signal or beam occurs. In one example implementation, when the LTM MR MAC CE is triggered by a first candidate reference signal / beam and sends information about a second candidate reference signal / beam containing an event / condition that does not meet the configuration, a disable timer is also started for the second candidate reference signal / beam. In other words, if an LTM MR MAC CE containing information about at least one candidate reference signal / beam is triggered, at least one disable timer Tprohibit_LTM is started for at least one candidate reference signal / beam, even if some candidate reference signals / beams may not meet the configured event / condition.

[0122] In some embodiments, the timer is a first timer, the reference signal or beam is a first reference signal or beam, and the measurement report may include information about the first reference signal or beam. If a third timer associated with a third reference signal or beam is running, the terminal device 110 may exclude information about the third reference signal or beam from the measurement report. In one example implementation, if the LTM MRMAC CE is triggered by the first candidate reference signal / beam when the timer is disabled for a third candidate reference signal / beam (which is different from the first candidate reference signal / beam for which its LTM MR MAC CE is triggered), then information about the first reference signal that meets the reporting criteria is included in the LTM MR MAC CE, while information about the third candidate reference signal / beam for which the timer is disabled is not included in the LTM MR MAC CE.

[0123] In some embodiments, terminal device 110 may transmit to network device 120 an indication of its capability to support event-triggered measurement reports based on a timer for each reference signal. Alternatively or additionally, terminal device 110 may transmit to network device 120 an indication of its capability to support event-triggered measurement reports based on a timer for each beam. Alternatively or additionally, terminal device 110 may transmit to network device 120 an indication of its capability to support event-triggered measurement reports based on a timer for each reference signal configured for a report. Alternatively or additionally, terminal device 110 may transmit to network device 120 an indication of its capability to support event-triggered measurement reports based on a timer for each beam configured for a report. In one example implementation, terminal device 110 may indicate its capability to support event-triggered measurement reports based on a disable timer for each configuration of candidate reference signals / beams in the report configuration.

[0124] In some embodiments, the capability indication may include the maximum number of disable timers that the terminal device supports running simultaneously. Alternatively or additionally, the capability indication may include the maximum number of reference signals with disable timers that the terminal device supports running simultaneously. Alternatively or additionally, the capability indication may include the maximum number of beams with disable timers that the terminal device supports running simultaneously. Alternatively or additionally, the capability indication may include the maximum number of timers that the terminal device supports running simultaneously for each report configuration. Alternatively or additionally, the capability indication may include the maximum number of disable timers or the maximum number of reference signals / beams with disable timers that the terminal device supports running simultaneously for each event type. In an example implementation, the capability may indicate the maximum number of disable timers or candidate reference signals / beams that the UE can support simultaneously.

[0125] In some embodiments, if a timer is running, the terminal device 110 may not transmit a request for resources used for measurement reporting. In an example implementation, during the UEIBM process, disabling the timer can be applied to uplink signals requesting resources for event-triggered reporting.

Figure 2A and Figure 2BProcesses 200 A and 200 B can be executed together, or they can be executed independently of processes 200 A and 200 B.

[0127] like Figure 2C As shown, terminal device 110 determines (234) that a trigger event has occurred. Terminal device 110 triggers (225) a periodic measurement report associated with the trigger event based on the state of a timer. In this way, timers are prohibited from being applied to the periodic reports triggered by the event. Therefore, resource overhead can be reduced.

[0128] In some embodiments, the triggering event may be associated with a cell handover procedure (e.g., an LTM procedure). The prohibition timer may be implemented as Tprohibit_LTM. Alternatively or additionally, the triggering event may be associated with a beam management procedure. In other words, the prohibition timer may be implemented as Tprohibit_UEIBM and may be applied to UE-initiated or event-driven beam management measurement reports, such as UEIBM reports or UE event-triggered beam management reports.

[0129] In some embodiments, network device 120 may transmit (231) configuration information 232 for a timer to terminal device 110. Terminal device 110 may receive (232) configuration information 232 for a timer from network device 120.

[0130] In some embodiments, the triggering event can be associated with a reporting configuration, and a timer can be associated with a reporting configuration. For example, it can be... Figure 2A In the embodiment of process 200 A, a timer for disabling periodic reporting is used.

[0131] In some embodiments, if the timer is in a non-running state or an expired state, the terminal device 110 may trigger a periodic measurement report. In some embodiments, if the timer is in a running state, the terminal device 110 may not trigger a periodic measurement report.

[0132] In some embodiments, the occurrence of a trigger event can be determined based on measurements of a reference signal or beam, and a timer is associated with the reference signal or beam. Alternatively, the occurrence of a trigger event can be determined based on measurements of a reference signal or beam associated with a reporting configuration, and a timer is associated with the reference signal or beam associated with the reporting configuration. For example, it can be... Figure 2B In the embodiment of process 200 B, a timer for disabling periodic reporting is used. For example, if the timer for the reference signal / beam is running, the terminal device 110 may not trigger a periodic measurement report for the reference signal / beam, or a periodic measurement report containing information about the reference signal / beam.

[0133] In some embodiments, if a periodic measurement report is triggered, the terminal device 110 may transmit (236) a measurement report 237 for the periodic measurement report to the network device 120. Therefore, the network device 120 may receive (238) the measurement report 237 from the terminal device 110.

[0134] In some embodiments, a measurement report for periodic measurement reporting may be carried in the UCI report. Alternatively or additionally, a measurement report for periodic measurement reporting may be carried in the MAC CE report. In the example implementation, the measurement report for periodic measurement reporting may refer to a UCI report or a MAC CE report that reports event triggering information.

[0135] In some embodiments, when a periodic measurement report is triggered, the terminal device 110 may perform at least one of the following: triggering the generation of a measurement report; instruction multiplexing and assembly process to generate and transmit the measurement report; determining that uplink authorization is available for transmitting the measurement report; or transmitting the measurement report.

[0136] In some embodiments, terminal device 110 may receive from network device 120 an indication of the time interval between measurement reports for periodic measurement reports. Alternatively or additionally, terminal device 110 may receive from network device 120 an indication of the number of measurement reports for periodic measurement reports. In an example implementation, the LTM event-triggered reporting configuration may be configured to periodically report LTM MR MAC CE. In some examples, the periodicity and number of reports to be transmitted in periodic measurement reports may be configured by the network device.

[0137] In some embodiments, if a periodic measurement report is triggered, the terminal device 110 can start or disable the timer.

[0138] In some embodiments, terminal device 110 may start a timer based on triggering the last measurement report for periodic measurement reports to the network device. In one example implementation, for periodic reports, timer Tprohibit_LTM is prevented from starting when the last periodic report is triggered.

[0139] In some embodiments, terminal device 110 may start a timer based on triggering the Nth measurement report for periodic measurement reports to the network device, where N is configured by the network device. In one example implementation, for periodic reports, when the Nth periodic report is triggered, timer Tprohibit_LTM is disabled, where N refers to the number of periodic reports to be transmitted.

[0140] In some embodiments, terminal device 110 may start a timer based on triggering a first measurement report for a periodic measurement report to the network device. In one example implementation, timer Tprohibit_LTM is prevented from starting when a periodic event trigger report is triggered.

[0141] In some implementations, the duration of the timer's operation is the greater of the timer's timer value and the reporting duration of the periodic measurement report. In one example implementation, a prohibition period configured for the report is applied such that the maximum value between the time period for using the prohibition timer Tprohibit_LTM and the reporting duration for N periodic reports is applied. If the timer's timer value is shorter than the reporting duration of the periodic measurement report, the terminal device 110 can keep the timer running until the time of the last measurement report for the periodic measurement report to the network device. For example, if the prohibition timer Tprohibit_LTM expires before the Nth / last periodic report, the time of transmitting the last report can be applied as the prohibition expiration of timer Tprohibit_LTM. Alternatively, the timer's timer value is not shorter than the reporting duration of the periodic measurement report. In one example implementation, a prohibition period configured for the report is applied such that the minimum value between the time period for using the prohibition timer Tprohibit_LTM and the reporting duration for N periodic reports is applied.

[0142] In some embodiments, terminal device 110 may transmit to network device 120 an indication of its ability to support periodic reporting based on a timer-disabled mechanism for event-triggered measurement reports. In some embodiments, the indication of capability may include the maximum number of timers that the terminal device can support running simultaneously.

[0143] In some embodiments, if a timer is running, the terminal device 110 may not transmit a request for resources used for measurement reporting. In an example implementation, during the UEIBM process, disabling the timer can be applied to uplink signals requesting resources for event-triggered reporting.

[0144] Figure 3 A schematic diagram illustrating an example process 300 for disabling a timer for a report configuration according to some embodiments of this disclosure is provided. For discussion purposes, reference will be made to... Figure 1A Describe process 300. Process 300 may involve UE 310, serving cell 331, and (multiple) candidate cells 332. UE 310 may be...

Figure 1A The process 300 is described in the communication environment 100, but this process can also be applied to other communication scenarios. Process 300 can be... Figure 2A A specific example of process 200 A in the document.

[0145] like Figure 3 As shown, in step 301, UE 310 receives LTM configuration. LTM configuration may include at least one of the following: measurement reference signal configuration, at least one reporting configuration for event-triggered reporting, and configuration information for an LTM prohibition timer (Tprohibit_LTM) associated with the at least one reporting configuration. At step 302, UE 310 performs measurements on at least one serving cell 331 and one or more candidate cells based on the measurement reference signal configuration.

[0146] In step 303, UE 310 determines that at least one reporting event has been triggered for the first reference signal RS1 in reporting configuration ID1. For example, the first reference signal RS1 may meet the reporting criteria during the duration of TTT. In step 304, UE 310 triggers LTM MR MAC CE, which includes RS1 in the measurement report. The Tprohibit_LTM timer starts for reporting configuration ID1.

[0147] In step 305, UL resources for the measurement report are allocated (dynamically, pre-configured, or using any available uplink grant). At step 306, UE 310 transmits the LTM MR MAC CE to serving cell 331.

[0148] At step 307, if another reporting event is triggered for a second reference signal RS2 under the same reporting configuration ID1 (e.g., the second reference signal RS2 can meet the reporting criteria during the duration of TTT), then UE 310 determines whether Tprohibit_LTM for reporting configuration ID1 is valid. If Tprohibit_LTM for reporting configuration ID1 is active, then UE 310 does not trigger a new LTM MR MAC CE for the same reporting configuration.

[0149] In step 308, the Tprohibit_LTM timer expires for report configuration ID1. In step 309, after Tprohibit_LTM expires, UE 310 checks whether the second reference signal RS2 meets the reporting criteria. If the second reference signal RS2 meets the reporting criteria when Tprohibit_LTM expires, UE 310 triggers an LTM MR MAC CE for report configuration ID1, which includes RS2 in the measurement report. The Tprohibit_LTM timer restarts for report configuration ID1. In step 311, UE 310 transmits an updated LTM MR MAC CE to serving cell 331.
