[0014] This disclosure provides embodiments of mobility operation methods, communication devices, systems, storage media, and program products.

[0015] In a first aspect, embodiments of this disclosure provide a mobility operation method, the method comprising: determining a measurement period of a second measurement based on a stopped first measurement; wherein the stopped first measurement is determined by a first condition or received first information, the first measurement includes an L1 measurement for triggering mobility operation, and the second measurement includes at least one of the following: an L3 measurement for triggering mobility operation, and an L1 measurement that has not been stopped.

[0016] In the above embodiments, the terminal can determine to stop all or part of the L1 measurements through dynamic indication or according to the first condition, and adjust the measurement cycle of the L3 measurements and the measurement cycle of the L1 measurements that have not been stopped based on the stopped first measurements, thereby rationally allocating measurement resources and improving the measurement efficiency of L1 and L3 measurements.

[0017] In conjunction with some embodiments of the first aspect, in some embodiments, determining the measurement period of the second measurement based on the stopped first measurement includes: determining a first parameter based on the stopped first measurement; and determining the measurement period of the second measurement based on the first parameter; wherein the first parameter includes at least one of the following: a first sharing factor, which is used to indicate the sharing of measurement resources for L1 measurements that do not require a measurement interval; and a first carrier-specific scaling factor, which is used to indicate the sharing of measurement resources for first measurement objects that require a measurement interval.

[0018] In the above embodiments, after determining to enable and / or stop L1 measurement based on the first information, parameters such as the first sharing factor and carrier-specific scaling factor can be updated to accurately quantify the allocation ratio of measurement resources, optimize the latency requirements in the coexistence scenario of L1 and L3 measurements, and avoid resource waste.

[0019] In conjunction with some embodiments of the first aspect, in some embodiments, the first measurement object includes: the cell measured by L1 and / or the frequency point measured by L3.

[0020] In the above embodiments, by clearly defining the measurement object as a cell or frequency point, the UE's targeting of the measurement target is improved, the resource adjustment strategy is made more refined, and the measurement efficiency is improved.

[0021] In conjunction with some embodiments of the first aspect, in some embodiments, determining the measurement period of the second measurement based on the first parameter includes at least one of the following: determining the measurement period of L1 measurement that does not require a measurement interval based on a first sharing factor; determining the measurement period of L3 measurement that requires a measurement interval based on a first carrier-specific scaling factor; and determining the measurement period of L1 measurement that requires a measurement interval based on a first carrier-specific scaling factor.

[0022] In the above embodiments, after determining to start and / or stop the first measurement based on the first information, the allocation ratio of measurement resources can be accurately quantified by updating the parameters corresponding to various types of measurements, thereby avoiding resource waste.

[0023] In conjunction with some embodiments of the first aspect, in some embodiments, when the first parameter is the first sharing factor, determining the first parameter based on the stopped first measurement includes: determining at least one of a first number of cells, a second number of cells, and a third number of cells based on cells in the L1 measurements that do not require a measurement interval among the L1 measurements that have not been stopped; wherein the first number of cells is the number of neighboring cells, the second number of cells is the number of neighboring cells located in the active TCI state list, and the third number of cells is the number of neighboring cells not located in the active TCI state list; and determining the first sharing factor based on at least one of the first number of cells, the second number of cells, and the third number of cells.

[0024] In conjunction with some embodiments of the first aspect, in some embodiments, when the number of the first cell is 1 and the measurement resources of the serving cell and the neighboring cell overlap or are adjacent in the time domain, the first sharing factor is 2; when the number of the first cell is 1 and the measurement resources of the serving cell and the neighboring cell do not overlap or are adjacent in the time domain, the first sharing factor is 1; when the number of the first cell is greater than 1 and the number of the second cell is 0, the first sharing factor is 3 times the number of the third cell; when the number of the first cell is greater than 1 and the number of the second cell is not 0, the first sharing factor is 3 times the number of the second cell.

[0025] In the above embodiments, the sharing factor is dynamically adjusted based on the number of neighboring cells in the active TCI status list, resources are preferentially allocated to key cells, redundant measurements of inactive TCI status cells are reduced, and the UE's computational burden is reduced.

[0026] In conjunction with some embodiments of the first aspect, in some embodiments, when the first parameter is a first carrier-specific scaling factor, determining the first parameter based on the stopped first measurement includes: obtaining the number of first measurement objects by the number of frequency points of L3 measurement required for the required measurement interval and the number of cells of L1 measurement required for the required measurement interval in the unstopped L1 measurement; and determining the first carrier-specific scaling factor based on the number of first measurement objects.

[0027] In the above embodiments, the measurement interval requirements of frequency points and cells are considered by carrier-specific scaling factor (CSSF) to ensure the rationality of resource allocation in scenarios requiring measurement intervals and avoid conflicts caused by simultaneous measurement of multiple frequency points.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the first information is further used for at least one of the following: instructing the terminal whether to start or stop the first measurement based on a first condition; instructing a threshold in the first condition; instructing a hysteresis value in the first condition; instructing trigger time information of the first condition.

[0029] In the above embodiments, by sending a first condition to the terminal to trigger the start and / or stop of the first measurement, the terminal can start and / or stop the measurement according to the actual measurement results, thereby reasonably allocating measurement resources.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, a first condition is used to enable and / or disable the first measurement. When the first condition is used to disable the first measurement, the first condition includes at least one of the following: the measurement result of the L3 measurement of the serving cell and / or neighboring cells is greater than or equal to a first threshold; the measurement result of the L3 measurement of the best beam of the serving cell is greater than or equal to a second threshold; the measurement result of the L3 measurement of the worst beam of the serving cell is less than or equal to a third threshold; and the measurement result of the L3 measurement of neighboring cells is better than the measurement result of the L3 measurement of the serving cell.

[0031] In the above embodiments, by defining specific activation conditions, it is ensured that the UE performs L1 measurement only when necessary, avoiding repeated measurement of cells with stable signal quality, and reducing power consumption and signaling overhead.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, when the first condition is used to enable the first measurement, the first condition includes at least one of the following: the measurement result of the L3 measurement of the serving cell and / or neighboring cells is less than or equal to a first threshold; the measurement result of the L3 measurement of the best beam of the serving cell is less than or equal to the L3 threshold; the measurement result of the L3 measurement of the worst beam of the serving cell is greater than or equal to a third threshold; the measurement result of the L3 measurement of the serving cell is better than the measurement result of the L3 measurement of the neighboring cells.

[0033] In the above embodiments, by defining specific stop conditions, it is ensured that the UE performs L1 measurements only when necessary, avoiding repeated measurements on cells with stable signal quality, and reducing power consumption and signaling overhead.

[0034] In some embodiments of the first aspect, the method further includes: determining a first frequency point where the cell to be measured is located; and determining whether to start or stop the first measurement based on whether the measurement results of L3 measurements of each cell on the first frequency point meet a first condition.

[0035] In the above embodiments, the L3 measurement results related to the first measurement are evaluated at the cell level, and L1 measurement is only enabled when specific cells meet the conditions, thereby improving the accuracy of resource adjustment and avoiding the waste of resources in full-band measurement.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: determining a first frequency point where the cell for the first measurement is located; and determining whether to start or stop the first measurement for each cell on the first frequency point based on whether the first measurement result in the L3 measurement results of each cell on the first frequency point meets the first condition.

[0039] In the above embodiments, when the network requests the L1 measurement results that have been stopped, the UE is allowed to calculate approximate values ​​or ranges based on the L3 measurement results (such as L1-RSRP calculation based on L3 optimal beam), which ensures the continuity of network optimization decisions and reduces data loss caused by the cessation of measurement.

[0041] In the above embodiments, by reporting the calculated L1 measurement results (such as range and extreme values), the data loss caused by stopping actual measurement is compensated, which supports the network to make rapid decisions (such as handover or beam adjustment) and at the same time reduces the measurement load of the UE.

[0086] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0087] In some embodiments, for Layer 3 (L3) mobility, in a communication system (e.g., an NR system), the network sends measurement configurations to the connected UE via RRC messages. The UE performs measurements within the same frequency band, across different frequencies, or across different systems according to the configuration and reports the results to the network. The measurement configuration includes a measurement identifier (MeasId), a measurement object (MeasObject), and a reporting configuration (ReportConfigNR). Each set of measurements is associated with an index, and the UE only performs the corresponding measurements according to the configuration and reports the results. This mechanism enables the UE to effectively complete multi-band and cross-system measurements, supporting network optimization and management. To support L3 mobility, L3 measurement requirements are also defined.

[0088] In some embodiments, L1 / L2 Triggered Mobility (LTM) can also be referred to as a Layer 1 and Layer 2 (L1 / L2) handover mechanism. The network receives L1 measurement reports from the terminal. Based on the received L1 measurement results, the network can send a Cell Switch Command signaling to the terminal via the Medium Access Control Element (MAC CE) to implement the process of changing the terminal's serving cell. Compared to traditional RRC-triggered handover, this reduces latency, overhead, and downtime during handover. Depending on the network configuration, the UE can perform LTM L1 measurements on the current special cell (SpCell) and neighbor cells.

[0089] The LTM configuration includes:

[0090] LTM uses LTM-config to configure LTM configuration information.

[0091] The LTM configuration information may include, but is not limited to, one or more of the following:

[0092] LTM Reference Configuration;

[0093] One or more candidate cell configurations (candidate cell configurations are added, modified, or deleted through the LTM candidate deletion list (ltm-CandidateToReleaseList) and the LTM candidate addition / modification list (ltm-CandidateToAddModList);

[0094] LTM CSI resource configuration; etc.

[0095] The candidate cell configuration can be configured through LTM-Candidate, and may include, but is not limited to, one or more of the following information:

[0096] Candidate configuration identifier;

[0097] Candidate community identifier;

[0098] Candidate configurations (represented by Radio Resource Control Reconfiguration (RRCReconfiguration)); etc.

[0099] For LTM, Layer 1 Reference Signal Received Power (L1-RSRP) measurement requirements are defined. According to these requirements, LTM L1-RSRP measurement resources are divided into three categories based on TCI status: serving cell, cells on the active TCI status list, and cells not on the active TCI status list. The UE is expected to perform measurements for these three cell categories using Time Division Multiplexing (TDM) and adhere to the corresponding measurement delay requirements, acquiring and reporting the measurement results.

[0100] In some embodiments, when both of the above features are configured simultaneously, the UE needs to perform L1 and L3 measurement tasks. Due to limited UE measurement resources (RF resources, baseband resources, etc.), simultaneous execution is not possible and time-division / sequential execution is required. To reflect the time-division execution measurement behavior, various expansion factors are considered when defining the measurement requirements for these different measurement tasks:

[0101] In some embodiments, for L3 mobility: Table 1 shows the measurement period for intra-frequency measurements without gaps (FR2) in the FR2 band. Table 1

[0102] Where M: is the spreading factor determined based on the product of the number of samples required for measurement and the number of Rx scans performed by the UE in the FR2 band.

[0103] K FR K is a scaling factor determined based on the frequency range of the measured object and the subcarrier spacing (SCS) of the corresponding synchronization signal and physical broadcast channel block (SSB). For the FR2-1 band, K FR=1. For the FR2-2 band: if the SSB subcarrier spacing of the detected cell is 120kHz, K FR =1; if the SSB subcarrier spacing of the detected cell is 480kHz, KFR=2; if the SSB subcarrier spacing of the detected cell is 960kHz, KFR=3 (For FR2-1, KFR=1. For FR2-2: KFR=1 if the SCS of the SSB of the cell being detected is 120 kHz, KFR=2 if the SCS of the SSB of the cell being detected is 480 kHz, and KFR=3 if the SCS of the SSB of the cell being detected is 960 kHz).

[0104] Kp reflects the allocation of measurement opportunities between measurements that do not require a measurement interval and measurements that do require a measurement interval. Generally, measurements that do not require a measurement interval must give way to measurements that require a measurement interval, meaning they can only be performed at times outside of the measurement interval's scheduled time (SSB-based RRM measurement timing configuration, SMTC). p The scaling factor K is used for measuring a frequency layer without a gap. p =N total / N available .

[0105] K layer1_measurement K is the spread factor introduced when L3 measurement resources (SMTC) and L1 measurement resources (SSB) completely overlap in the time domain. layer1_meas urement = 1.5.

[0106] K layer1_measurement=1, if all of the reference signals configured for RLM, BFD, CBD, or L1-RSRP for beam reporting on any FR2 serving frequency (in the same band and outside the measurement gap) are not fully overlapped by intra-frequency SMTC occasions, or if all of the reference signals configured for RLM, BFD, CBD, or L1-RSRP for beam reporting on any FR2 serving frequency (in the same band and outside the measurement gap) are not fully overlapped by intra-frequency SMTC occasions, or if all of the reference signals configured for RLM, BFD, CBD, or L1-RSRP for beam reporting on any FR2 serving frequency (in the same band and outside the measurement gap), although fully covered by intra-frequency SMTC occasions, are not fully overlapped by any SSB symbol, Received Signal Strength Indicator (SSS) symbol, or Received Signal Strength Indicator (SSS) symbol, are not fully overlapped by intra-frequency SMTC occasions. Indication (RSSI) symbols, and the symbols preceding and following each consecutive SSB and RSSI symbol, do not overlap (provided that SSB-ToMeasure and SS-RSSI-Measurement are configured, where the SSB symbol is represented by the union of mergeable SSB-ToMeasure values ​​from all configured measurements on the same serving carrier, and the RSSI symbol is indicated by SS-RSSI-Measurement). (If all of the reference signal configured for RLM, BFD, CBD, or L1-RSRP for beam reporting on any FR2 serving frequency in the same band outside the measurement gap and fully-overlapped by intra-frequency SMTC occasions, are not overlapped with any of the SSB symbols and the RSSI symbols.)and 1 symbol before each consecutive SSB symbols and the RSSI symbols,and 1 symbol after each consecutive SSB symbols and the RSSI symbols,given that SSB-ToMeasure and SS-RSSI-Measurement are configured,where SSB symbols are indicated by the union set of SSB-ToMeasure from all the configured measurement objects on the same carrier serving which can be merged.and RSSI symbols are indicated by SS-RSSI-Measurement);,

[0107] Otherwise, K layer1_measurement =1.5.

[0108] CSSF: Carrier-specific scaling factor, which reflects the sharing of measurement resources among multiple frequency layers under test.

[0109] In some embodiments, Table 2 shows the measurement period for intra-frequency measurements with gaps (FR2) for a FR2 band. Table 2

[0110] K gap This reflects the proportion of available measurement intervals that were not dropped after being judged according to the measurement interval priority rules.

[0111] K gap This is a scaling factor used to measure the SSB frequency layer in the relevant measurement interval mode. When the UE is not configured or does not support concurrent measurement intervals (GAPs) or multi-subframe measurement intervals (MUSIM gaps), K... gap =1. Otherwise, K gap =Ntotal / N available , where N available and N total The calculation method is as follows (K is the scaling factor for a SSB frequency layer to be measured within an associated measurement gap pattern). gap =1 when the UE is not configured with or the UE does not support concurrent GAPs or MUSIM gaps.Otherwise,K gap =N total / N available ,where N available and N total (are calculated as follows):

[0112] For a window W of duration max(SMTC period, xRP_max), where xRP_max is the maximum xRP across all configured per-UE GAPs, periodic MUSIM gaps, and per-FR GAPs within the same FR as the SSB frequency layer, and starting from the beginning of any SMTC occasion:

[0113] N totalIt is the total number of SMTC occasions that are covered by instances of the associated measurement gap within the window W, including those that overlapped with other GAP and MUSIM gap occasions within the window.

[0114] N available This refers to the number of SMTC occasions covered by instances of the non-dropped associated measurement gap within the window W after accounting for GAP and MUSIM gap collisions by applying the collision rules for GAP and MUSIM gap.

[0115] When the configured GAP is an active Pre-MG or MG, xRP = MGRP; when the configured GAP is an NCSG, xRP = VIRP; and for periodic MUSIM gaps, xRP = MGRP.

[0116] When concurrent GAPs are configured and N available When N is 0, the requirements in this clause do not apply.

[0117] When the UE supports [MUSIM-GapConfig-17] and the configured aperiodic MUSIM gap collides with the measurement gap associated with the target frequency layer (where the MUSIM gap collision rule is applied), the identification period for the target intra-frequency cell is expected to be longer.

[0118] In some embodiments, for the serving cell L1-RSRP, Table 3 shows the measurement period (TL1-RSRP_Measurement_Period_SSB) for UEs that do not have the capability to measure the round-trip delay (RTD) greater than the cyclic prefix (CP) in FR2 for measuring the serving cell SSB. Table 3

[0119] M: Measurement spread factor determined based on network parameter configuration. If the higher layer parameter "timeRestrictionForChannelMeasurement" is configured, then M=1; otherwise, M=3.

[0120] N: Indicates the number of Rx scans performed by the UE in the FR2 band.

[0121] P: This reflects the allocation of measurement opportunities between L1 and L3 measurements. L1 measurements have a lower priority than L3 measurements, meaning that L1 measurements can only be performed at times other than those designated for L3 measurements. For FR1, based on the assumption of an omnidirectional UE receiving antenna, L1 measurements only need to avoid gap-based L3 measurements; while for FR2, based on the assumption of a directional UE receiving antenna, L1 measurements need to avoid both gap-based and SMTC-based L3 measurements.

[0122] There are currently two methods for calculating the expansion coefficient P in existing protocols:

[0123] 1. Precise modeling based on mathematical formulas: Precise formulas for calculating the SSB cycle, SMTC cycle, and measurement interval cycle of cells with different Physical Cell Identifiers (PCIs) based on the serving cell's SSB cycle.

[0124] 2. Rough calculation based on Ntotal / Navailable: Since the configuration of measurement intervals can be more flexible, the occurrence of measurement intervals is no longer completely regular. Therefore, it is difficult to accurately model the available SSB measurement opportunities using mathematical formulas. Thus, a new expression method is introduced.

[0125] P sharing factor The spreading factor introduced by P is mainly used when the L3 measurement resource (SMTC) and the L1 measurement resource (SSB) are completely overlapped in the time domain, and Psharing factor = 3.

[0126] P L1_sharing There are two ways to use it:

[0127] 1. For inter-cell multiple transmission and reception points (mTRP), sharing of measurement resources between multiple-input multiple-output (MIMO) L1-RSRP measurements and L1-RSRP measurements with cells having different PCIs:

[0128] If SSB resources for cells with different PCIs are configured for L1-RSRP measurements, and P is used sharing_factor,CDP Furthermore, any symbols of the serving cell and the SSB of cells with different PCIs overlap or are adjacent in the time domain, P L1_sharing =2; otherwise, P L1_sharing =1(P L1_sharing=2, if SSB resource from the cell with different PCI is configured for L1-RSRP measurement, and Psharing_factor, CDP is used, and any symbol of the SSBs from serving cell and cell with different PCI are overlapping or adjacent (in time domain).P L1_sharing =1, otherwise).

[0129] 2. For LTM to neighboring L1-RSRP measurements, the sharing factor for measurement resources between MIMO L1-RSRP and LTM L1-RSRP measurements:

[0130] P L1_sharing The definition is as follows:

[0131] When the number of neighboring cells configured with SSB-based L1-RSRP measurement is 1:

[0132] If the SSBs of the serving cell and neighboring cells have any sign overlap or adjacent P in the time domain L1_sharing =2(PL1_sharing=2 if any symbol of the SSBs from serving cell and neighbor cell are overlapping or adjacent(in time domain));

[0133] Otherwise, P L1_sharing =1.

[0134] When the number of neighboring cells configured with SSB-based L1-RSRP measurement is more than 1, PL1_sharing = 3.

[0135] In some embodiments, for LTM L1-RSRP, Table 4 shows the measurement period (TIntra_L1-RSRP_Measurement_Period_SSB) for measuring co-frequency L1-RSRP in the FR2 band for UEs that do not have the measurement capability to measure round-trip delay (RTD) greater than cyclic prefix (CP). Table 4

[0136] M: Measurement spread factor determined based on network parameter configuration. If the higher layer parameter "timeRestrictionForChannelMeasurement" is configured, then M=1; otherwise, M=3.

[0137] N: Indicates the number of Rx scans performed by the UE in the FR2 band.

[0138] P: This reflects the allocation of measurement opportunities between L1 and L3 measurements. L1 measurements have a lower priority than L3 measurements, meaning that L1 measurements can only be performed at times other than those designated for L3 measurements. For FR1, based on the assumption of an omnidirectional UE receiving antenna, L1 measurements only need to avoid gap-based L3 measurements; while for FR2, based on the assumption of a directional UE receiving antenna, L1 measurements need to avoid both gap-based and SMTC-based L3 measurements.

[0139] P L1_sharing This reflects the allocation mechanism of measurement resources in LTM L1-RSRP measurements. LTM L1-RSRP measurement resources are divided into three categories based on TCI status: serving cell, cells on the active TCI status list, and cells with inactive TCI status.

[0140] P L1_sharing The definition is as follows:

[0141] When the number of neighboring cells configured with SSB-based L1-RSRP measurement is 1:

[0142] If the SSBs of the serving cell and neighboring cells have any sign overlap or adjacent P in the time domain L1_sharing=2(PL1_sharing=2 if any symbol of the SSBs from serving cell and neighbor cell are overlapping or adjacent(in time domain));

[0143] Otherwise, P L1_sharing =1.

[0144] When the number of neighboring cells configured with SSB-based L1-RSRP measurement is greater than 1:

[0145] If none of the intra-frequency neighbor cells or inter-frequency neighbor cells without gap are in the active TCI state list, then... L1_sharin g = 3 * N Neighbor_Cell ; where N Neighbor_Cell This refers to the number of neighbor cells whose TCI state(s) are not in the active TCI state list (in intra-frequency and inter-frequency measurement scenarios without gaps).

[0146] Otherwise, P L1_sharing= 3 * NNeighbor_Cell_in_list; where NNeighbor_Cell_in_list represents the number of neighbor cells (including intra-frequency neighbor cells and inter-frequency neighbor cells without gap) whose TCI state(s) are in the active TCI state list. No requirements are defined for any other cell(s) whose TCI state(s) is not in the active TCI state list.

[0147] In some embodiments, LTM and L3 mobility measurements are two independent configuration processes, and there are complex measurement resource allocation issues between them, as shown in Figure 2A. For measurements without measurement intervals (Measurement without MG), L3 measurements have higher priority than L1 measurements and are allocated measurement resources preferentially; for measurements with measurement intervals (Measurement with MG), L3 and L1 measurements will share measurement resources.

[0148] Both LTM and L3 mobility procedures are used for mobility purposes. Under existing mechanisms, L3 measurement is a prerequisite for enabling L1 measurement. L1 measurement is performed only after L3 measurement is reported, but L3 measurement continues simultaneously with L1 measurement. RRM introduces complex measurement requirements considering the coexistence of these two processes when defining relevant measurement latency requirements. However, both measurements are redundant for the UE and complicate UE behavior. This solution proposes a method for evaluating the enabling / disabling of L1 mobility measurement and UE behavior based on L3 results, simplifying UE measurement.

[0149] Figure 2B is an interactive schematic diagram of a mobility operation method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a mobility operation method, which includes:

[0159] In some embodiments, L1 measurement includes L1 measurement that does not require a measurement interval and / or L1 measurement that requires a measurement interval.

[0160] In some embodiments, L1 measurement may include L1 measurement in different frequency bands, such as L1 measurement in frequency range 1 (FR1) and L1 measurement in frequency range 2 (FR2).

[0161] Step S220: Terminal 101 determines the measurement cycle of the second measurement.

[0162] In some embodiments, the terminal may determine, based on first information, a first measurement that is stopped and / or started, and determine the measurement cycle of a second measurement based on the first measurement that is stopped and / or started; wherein the second measurement may include an L3 measurement for triggering mobility operation and / or an L1 measurement that is not stopped.

[0163] In some embodiments, L3 measurement may include at least one of L3 measurement, Radio Resource Management (RRM) measurement, and cell measurement. For simplicity, all of these will be referred to as L3 measurement in the following embodiments.

[0164] In some embodiments, L3 measurement may be applicable to at least one of the following: non-serving cell; serving cell; resource set; measurement object; frequency point; candidate cell; neighboring cell; beam. Wherein, non-serving cell may include non-serving SPCell; serving cell may include serving SPCell.

[0165] In some embodiments, L3 measurement may include intra-frequency L3 measurement and / or inter-frequency L3 measurement.

[0166] In some embodiments, L3 measurement may include L3 measurement without measurement interval and / or L3 measurement with measurement interval.

[0167] In some embodiments, L3 measurement may include L3 measurement in different frequency bands, such as L3 measurement in FR1, L3 measurement in FR22, etc.

[0168] In some embodiments, the terminal may determine the first measurement to be stopped and / or started based on the first information, and determine the measurement cycle of the L3 measurement based on the first measurement to be stopped and / or started.

[0169] In some embodiments, the terminal may determine the first measurement to be stopped and / or started based on the first information, and determine the measurement cycle of the first measurement that is not stopped and / or started based on the first measurement to be stopped and / or started.

[0170] In some embodiments, the terminal may determine the first measurement to be stopped and / or started based on first information, and determine a first parameter related to the L3 measurement; and determine the measurement period of the L3 measurement based on the first parameter. The first parameter related to the L3 measurement includes parameters used to determine the measurement period in the latency requirements of the L3 measurement, such as those shown in Tables 1 and 2; and the L3 measurement includes: L3 measurement without a measurement interval and L3 measurement with a measurement interval.

[0171] In some embodiments, the terminal may determine, based on first information, to stop and / or start a first measurement, and determine a first parameter related to the L1 measurement; and determine the measurement cycle of the L1 measurement that is not stopped and / or started based on the first parameter. The first parameter related to the L1 measurement includes parameters used to determine the measurement cycle in the latency requirements of the L1 measurement, as shown in Tables 3 and 4; and the L1 measurement includes: L1 measurement that does not require a measurement interval and L1 measurement that requires a measurement interval.

[0172] In some embodiments, the first parameter may include a first carrier-specific scaling factor (CSSF) to indicate the sharing of measurement resources by the first measurement object requiring a measurement interval, and may be represented as CSSF. within_gap The first measurement object requiring a measurement interval may include at least one of the cells requiring L1 measurement and the frequency points requiring L3 measurement.

[0173] In some embodiments, when the terminal determines that all L1 measurements have been stopped based on the first information, it can obtain the first number of measurement objects N according to the number of L3 measurement frequency points N2 required for the measurement interval, for example, N = N2; and then determine the first carrier-specific scaling factor CSSF based on the first number of measurement objects N. within_gap For example, the number of the first measured object can be used as the CSSF. within_gap .

[0174] In some embodiments, when the terminal determines, based on the first information, that all L1 measurements have not been stopped, it can obtain the first measurement target number N based on the number of L3 measurement frequency points N2 requiring measurement intervals and the number of cells of the first measurement requiring measurement intervals in the L1 measurements that have not been stopped, for example, N = N1 + N2; and then determine the first carrier-specific scaling factor (CSSF) based on the first measurement target number. within_gap .

[0175] In some embodiments, the first parameter may include a first sharing factor, used to indicate the sharing of measurement resources for L1 measurements that do not require a measurement interval, and may be represented as P. L1-sharing .

[0176] In some embodiments, if the terminal determines, based on the first information, that all L1 measurements have not been stopped, it can determine at least one of the following: the number of first cells, the number of second cells, and the number of third cells, according to the cells in the unstopped L1 measurements that do not require a measurement interval; and then determine the first sharing factor P based on at least one of the following: the number of first cells, the number of second cells, and the number of third cells. L1-sharing .

[0177] Where the number of the first cell is the number of neighboring cells, it can be represented as N. Cell The second cell count is the number of neighboring cells in the active TCI state list, which can be represented as NNeighbor_Cell_in_list; the third cell count is the number of neighboring cells not in the active TCI state list, which can be represented as N Neighbor_Cell .

[0178] In some embodiments, the number of the first cell is N. Cell =1, and when the measurement resources of the serving cell and neighboring cells overlap or are adjacent in the time domain, the first sharing factor P L1-sharing =2;

[0179] The number of cells in the first cell is N Cell =1, and the measurement resources of the serving cell and neighboring cells do not overlap or adjacency in the time domain, the first sharing factor P L1-sharing =1;

[0180] Number of cells in the first cell N Cell If the number of cells is greater than 1 and the number of cells in the second cell list (NNeighbor_Cell_in_list) is 0, the first sharing factor can be determined based on the number of cells in the third cell list. For example, the first sharing factor can be an integer multiple of the number of cells in the third cell list (K, P). L1-sharing =K*N Neighbor_Cell Where K can be 3 or other positive integers.

[0181] Number of cells in the first cell N Cell If the value is greater than 1 and the number of cells in the second cell list (NNeighbor_Cell_in_list) is not 0, the first sharing factor can be determined based on the number of cells in the second cell list. For example, the first sharing factor can be an integer multiple of the number of cells in the second cell list (K, P). L1-sharing =K*NNeighbor_Cell_in_list; where K can be 3 or other positive integers.

[0182] In some embodiments, if it is determined from the first information that all L1 measurements have not been stopped, the delay requirement for L3 measurements that do not require a measurement interval is not affected, i.e., it is not necessary to redetermine the first parameter associated with L3 measurements that do not require a measurement interval.

[0183] In some embodiments, if it is determined based on the first information that all L1 measurements have not been stopped, for L1 measurements that do not need to be measured, the first sharing factor P in their delay requirements needs to be re-determined. L1-sharingThis is used to represent the allocation mechanism of time-domain measurement resources in L1 measurements (such as LTM L1-RSRP). Measurement resources for L1 measurements can be divided into three categories based on TCI status: serving cell, cells on the active TCI status list, and cells with inactive TCI status. These three categories of cells fairly occupy all time-domain measurement resources available for LTM measurements. When determining to stop and / or start the first measurement based on first information, it is necessary to determine P. L1-sharing When determining the number of cells of each type (e.g., the number of first cells, the number of second cells, and the number of third cells), cells that are not measured (discarded cells), i.e., the first cells whose measurements are stopped, are excluded.

[0184] The first sharing factor P is shown in Table 4. L1-sharing It will be defined as follows:

[0185] When the number of non-dropped neighbor cells (first cell number) for SSB-based L1 measurements is configured to be 1, if the measurement resources of the serving cell and neighboring cells have any temporal symbol overlap or adjacency, P L1-sharing =2; otherwise, P L1-sharing =1;

[0186] When the number of non-dropped neighbor cells (number of first cells) configured for SSB-based L1 measurement is greater than 1, if none of the non-dropped co-frequency neighbor cells that do not require measurement intervals and the non-dropped inter-frequency neighbor cells that do not require measurement intervals have their TCI status in the active TCI status list, P L1-sharing =3*N Neighbor_Cell ; where N Neighbor_Cell This refers to the number of non-dropped neighbor cells (third cells) whose TCI status is not in the active TCI status list (in scenarios where no measurement interval is required for in-frequency and out-of-frequency measurements); otherwise, P L1-sharing = 3 * NNEighbor_Cell_in_list, where NNEighbor_Cell_in_list represents the number of non-dropped neighbor cells (including co-frequency neighbor cells and inter-frequency neighbor cells that do not require a measurement interval) whose TCI status is in the active TCI status list. There is no definition of requirements for other non-dropped cells whose TCI status is not in the active TCI status list.

[0187] In some embodiments, if it is determined based on the first information that all L1 measurements have not been stopped, for L3 measurements requiring a measurement interval, the first carrier-specific scaling factor (CSSF) in their delay requirements needs to be re-determined. within_gap For measurements requiring measurement intervals (including L1 and L3 measurements), CSSF within_gapThe derivation requires determining the number of the first measurement objects required for the measurement interval (including the number of neighboring cells for the L1 measurement interval and the number of frequency points for the L3 measurement interval), which is also necessary when deriving the first carrier-specific scaling factor (CSSF). within_gap The calculation will not include L1 measurements that require a measurement interval and have been stopped, but may include stopped same-frequency L1 measurements and different-frequency L1 measurements that require a measurement interval.

[0188] In some embodiments, if it is determined based on the first information that all L1 measurements have not been stopped, for L1 measurements requiring a measurement interval, the first carrier-specific scaling factor (CSSF) in their delay requirements needs to be re-determined. within_gap In deriving the first carrier-specific scaling factor (CSSF) within_gap The calculation will not include L1 measurements that require a measurement interval and have been stopped, but may include stopped same-frequency L1 measurements and different-frequency L1 measurements that require a measurement interval.

[0189] In some embodiments, when it is determined based on the first information to stop all L1 measurements, the delay requirement for L3 measurements that do not require a measurement interval is not affected.

[0190] In some embodiments, if it is determined based on the first information that all L1 measurements should be stopped, the terminal may not perform L1 measurements that do not require a measurement interval.

[0191] In some embodiments, if it is determined based on the first information that all L1 measurements should be stopped, for L3 measurements requiring a measurement interval, the first carrier-specific scaling factor (CSSF) in their delay requirements needs to be re-determined. within_gap In deriving the first carrier-specific scaling factor (CSSF) within_gap The calculation will not include L1 measurements that require a measurement interval and have already stopped, but may include stopped same-frequency or different-frequency L1 measurements that require a measurement interval.

[0192] In some embodiments, if it is determined based on the first information that all L1 measurements should be stopped, for L1 measurements requiring a measurement interval, the first carrier-specific scaling factor (CSSF) in their delay requirements needs to be re-determined. within_gap In deriving the first carrier-specific scaling factor (CSSF) within_gap The calculation will not include L1 measurements that require a measurement interval and have already stopped, but may include stopped same-frequency or different-frequency L1 measurements that require a measurement interval.

[0193] In the above embodiments, the network device can dynamically stop all or part of the L1 measurements by instructing the terminal to dynamically modulate the measurement cycle of the L3 measurements and the measurement cycle of the L1 measurements that are currently stopped and / or started, thereby rationally allocating measurement resources and improving the measurement efficiency of L1 and L3 measurements.

[0194] The communication method involved in the embodiments of this disclosure may include at least one of steps S210 to S220. For example, step S210 may be implemented as a standalone embodiment, step S220 may be implemented as a standalone embodiment, and steps S210+S220 may be implemented as standalone embodiments, but are not limited thereto.

[0198] Figure 2C is an interactive schematic diagram of a mobility operation method according to an embodiment of the present disclosure. As shown in Figure 2C, the embodiments of the present disclosure relate to a mobility operation method.

[0199] Step S211: Network device 102 configures the first condition to the terminal.

[0200] In some embodiments, the network device can configure trigger condition information for the terminal. The trigger condition information is used to indicate a first condition related to L1 measurement and / or a second condition related to L3 measurement. The first condition includes a trigger condition for starting and / or stopping L1 measurement; the second condition includes a trigger condition for starting and / or stopping L3 measurement.

[0201] In some embodiments, the terminal receives a first condition configured for it from the network device; and stops and / or starts the corresponding L1 measurement if it is determined that the first condition is met.

[0202] In some embodiments, the terminal receives a second condition configured for it from the network device; and stops and / or starts the corresponding L3 measurement if it is determined that the second condition is met.

[0203] In some embodiments, the network device may configure the terminal with: L3 measurement related configuration, L1 measurement related configuration, and trigger condition information.

[0204] In some embodiments, the network device may send first information to the terminal, and the first information may also be used for at least one of the following:

[0205] The terminal is instructed whether to enable or disable the first measurement based on a first condition. For example, the first indication indicates whether the terminal is allowed to enable or disable mobility measurement based on the first condition. The first indication may be a Boolean value, such as "1" indicating that the first condition is enabled and "0" indicating that the first condition is disabled.

[0206] The configuration related to the first condition may include:

[0207] The threshold in the first condition can be determined, for example, by comparing the corresponding measurement result with the threshold and determining whether the first condition is met based on the comparison result.

[0208] The hysteresis value in the first condition, for example, can be added to or subtracted from the corresponding measurement result and then compared with the threshold.

[0209] The trigger time information of the first condition can be used to indicate the opening time of the first condition, and to determine whether the first condition is met within the opening time.

[0210] In some embodiments, the first condition may include a first trigger condition, which is a trigger condition for stopping L1 measurement, and may specifically include at least one of the following:

[0211] The L3 measurement results of the serving cell and / or neighboring cells are greater than or equal to the first threshold;

[0212] The L3 measurement result of the best beam in the serving cell is greater than or equal to the second threshold;

[0213] The L3 measurement result of the worst beam in the serving cell is less than or equal to the third threshold;

[0214] The L3 measurement results of the neighboring cell are better than the L3 measurement results of the serving cell.

[0215] In some embodiments, the first condition may include a second triggering condition, which is a triggering condition for enabling L1 measurement, and may specifically include at least one of the following:

[0216] The L3 measurement results of the serving cell and / or neighboring cells are less than or equal to the first threshold;

[0217] The L3 measurement result of the best beam in the serving cell is less than or equal to the second threshold;

[0218] The L3 measurement result of the worst beam in the serving cell is greater than or equal to the third threshold;

[0219] The L3 measurement results of the serving cell are better than those of the neighboring cells.

[0220] It should be noted that the first threshold, second threshold, and third threshold in the first triggering condition can be the same or different; the first threshold, second threshold, and third threshold in the second triggering condition can be the same or different; the first threshold of the first triggering condition and the second triggering condition can be the same or different; the second threshold of the first triggering condition and the second triggering condition can be the same or different; and the third threshold of the first triggering condition and the second triggering condition can be the same or different.

[0221] Step S212: Terminal 101 evaluates whether the first condition is met.

[0222] In some embodiments, the terminal receives a first condition configured for it from the network device, evaluates the first condition according to actual needs, and stops and / or starts the L1 measurement associated with the first condition if it is determined that the first condition is met. Then, step S220 is executed based on the stopped and / or started L1 measurement, as shown in FIG2B, which will not be described in detail here.

[0223] In some embodiments, the terminal receives first information from the network device and evaluates the first triggering condition included in the first information according to actual needs. If it is determined that the first triggering condition is met, the first measurement associated with the first triggering condition is stopped. Then, step S220 is executed based on the stopped first measurement. A specific implementation is shown in FIG2B, which will not be described again here.

[0224] In some implementations, the terminal receives first information from the network device and evaluates the second triggering condition included in the first information according to actual needs. If it is determined that the second triggering condition is met, a first measurement associated with the second triggering condition is initiated. Then, based on the initiated first measurement, step S220 is executed. A specific implementation is shown in Figure 2B, which will not be described in detail here.

[0225] In some embodiments, the terminal may receive first information from the network device. The first information may include: indication information for indicating the cessation and / or initiation of L1 measurements, and a first condition for triggering the cessation and / or initiation of L1 measurements. The terminal can determine the L1 measurements to be stopped and / or started based on the network-configured measurement settings, the indication information included in the first information, and / or the first condition. The network-configured measurement settings may include measurement settings for L1 and L3 measurements, as well as related mobility settings, etc.

[0226] In some embodiments, the granularity at which the terminal evaluates the first condition can be set according to actual needs, and may include at least one of the following: cell granularity, frequency point granularity.

[0227] In some embodiments, the terminal may evaluate the first condition at the cell level: determine the first frequency point where the cell for the first measurement is located; evaluate whether the measurement results of L3 measurements of each cell on the first frequency point meet the first condition; and determine whether to enable or stop the first measurement based on the evaluation results.

[0228] In some embodiments, the terminal may evaluate the first condition at the frequency point granularity: determine the first frequency point where the cell for the first measurement is located; evaluate whether the first measurement result among the L3 measurement results of each cell on the first frequency point satisfies the first condition; and based on the evaluation result, determine whether to enable or stop the first measurement for each cell on the first frequency point; wherein the first measurement result may be at least one of the following: the best measurement result, the worst measurement result, several best measurement results, several worst measurement results, etc.

[0229] In the above embodiments, the network device can indicate to the terminal the trigger conditions for stopping and / or starting L1 measurement, so that the terminal can dynamically modulate the stopping or starting of L1 measurement according to the actual measurement results, and further dynamically modulate the measurement period of L3 measurement and the measurement period of L1 measurement based on the currently stopped and / or started L1 measurement, thereby rationally allocating measurement resources and improving the measurement efficiency of L1 measurement and L3 measurement.

[0230] The communication method involved in the embodiments of this disclosure may include at least one of steps S210, S211, and S220. For example, step S210 may be implemented as a standalone embodiment, step S211 may be implemented as a standalone embodiment, step S220 may be implemented as a standalone embodiment, step S211+S220 may be implemented as a standalone embodiment, and step S210+S211+S220 may be implemented as a standalone embodiment, but is not limited thereto.

[0231] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0232] Figure 2D is an interactive schematic diagram of a mobility operation method according to an embodiment of the present disclosure. As shown in Figure 2D, the embodiments of the present disclosure relate to a mobility operation method. After step S220 in Figures 2B and 2C, steps S230 and S240 are also included.

[0233] Step S230: Network device 102 sends second information to terminal 101.

[0234] In some embodiments, the network device may send second information to the terminal, the second information being used to request the measurement result of the first measurement.

[0235] In some embodiments, the terminal receives second information from the network device, the second information being used to request the measurement result of the L1 measurement; if the L1 measurement requested in the second information includes the first measurement, the terminal can infer the measurement result of the first measurement based on the measurement result of the L3 measurement associated with the first measurement, for example, RSRP.

[0236] In some embodiments, the terminal may also estimate the range of the measurement results of the first measurement, such as the range of RSRP values, based on the measurement results of the L3 measurement associated with the first measurement.

[0237] Step S240: Terminal 101 sends third information to network device 102.

[0238] In some embodiments, the terminal may send third information to the network device. The third information may include response information to the received second information, specifically including the measurement result of the L1 measurement requested by the network device.

[0239] In some embodiments, for the first measurement, the third information may include at least one of the following: the estimated measurement result, the range of the estimated measurement result, the minimum value of the estimated measurement result, and the maximum value of the estimated measurement result.

[0240] In some embodiments, for the first measurement, the third information may include a preset value, which may be an agreed value with the network device, such as a minimum value or a specific value supported by signaling.

[0241] In the above embodiments, the measurement result and / or range of the first measurement are calculated based on the measurement result of the L3 measurement corresponding to the first measurement and reported, thereby compensating for the data loss caused by stopping the first measurement, which can support rapid network decision-making and reduce the measurement burden on the terminal.

[0242] The communication method involved in the embodiments of this disclosure may include at least one of steps S210 to S240. For example, step S210 may be implemented as an independent embodiment, step S220 may be implemented as an independent embodiment, step S230 may be implemented as an independent embodiment, step S240 may be implemented as an independent embodiment, step S210+S220 may be implemented as an independent embodiment, step S223+S240 may be implemented as an independent embodiment, and step S210+S220+S230+S240 may be implemented as an independent embodiment, but is not limited thereto.

[0243] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0244] In some embodiments, when the UE performs L3 mobility measurement, the L1-RSRP measurement of a specific (partially performed) LTM cell under test is stopped (partial L1 measurement is stopped):

[0245] 1. For measurements that do not require a measurement interval (same frequency, different frequency, or different system):

[0246] 1.1. No L3 measurement delay requirement for measurement intervals is needed, so there is no impact;

[0247] 1.2. The parameter P is introduced in the L1 measurement delay requirement that does not require a measurement interval. L1_sharing This is used to represent the allocation mechanism of time-domain measurement resources in LTM L1-RSRP measurements. LTM L1-RSRP measurement resources are divided into three categories based on TCI status: serving cell, cells on the active TCI status list, and cells with inactive TCI status. These three categories of cells fairly occupy all time-domain measurement resources available for LTM measurements. L1_sharing A new counting method needs to be considered, excluding cells that are not being measured when counting various cell types:

[0248] Table 4 shows the measurement period (TIntra_L1-RSRP_Measurement_Period_SSB) for measuring L1-RSRP in the same frequency band for UEs that do not have the measurement capability to measure round-trip delay (RTD) greater than cyclic prefix (CP).

[0249] Among them, P L1_sharing The definition is as follows:

[0250] When the number of non-dropped neighboring cells configured with SSB-based L1-RSRP measurement is 1:

[0251] P L1_sharing=2, if any symbol of the SSBs from serving cell and neighbor cell are overlapping or adjacent (in time domain);

[0252] P L1_sharing =1, otherwise;

[0253] When the number of non-dropped neighboring cells configured with SSB-based L1-RSRP measurement is greater than 1:

[0254] If none of the non-dropped intra-frequency neighbor cells or non-dropped inter-frequency neighbor cells without a measurement interval are in the active TCI state list:

[0255] P L1_sharing =3*N Neighbor_Cell N Neighbor_Cell This refers to the number of non-dropped neighbor cells (to measure on intra-frequency and inter-frequency without gap) whose TCI state(s) are not in the active TCI state list (in scenarios where no measurement interval is required for intra-frequency and inter-frequency measurements).

[0256] Otherwise

[0257] PL1_sharing = 3 * NNeighbor_Cell_in_list, where NNeighbor_Cell_in_list represents the number of non-dropped neighbor cells (including intra-frequency neighbor cells and inter-frequency neighbor cells without gap) whose TCI state(s) are in the active TCI state list. No requirements are defined for any other non-dropped cells whose TCI state(s) is not in the active TCI state list.

[0258] 2. For measurements that require measurement intervals (same frequency, different frequency, or different system)

[0259] 2.1 The parameter CSSFwithin_gap introduced in the L3 measurement delay requirement requiring measurement intervals needs clarification regarding its counting range. For measurements requiring measurement intervals, CSSF counts the number of target frequency points for which measurements are performed during the required measurement intervals, including both L1 and L3 mobility measurements. Based on network indications or UE judgment, the UE may choose not to perform specific L1 mobility measurements that do not require measurement intervals (or only perform a portion of the L1 mobility measurements that do not require measurement intervals). The derivation of the CSSF parameter does not consider these types of L1-RSRPs where measurements are stopped.

[0260] For example, when deriving the carrier-specific scaling factor (CSSFwithin_gap) within the measurement gap, dropped inter / intra-frequency L1-RSRP measurements with measurement gaps that have been stopped will not be included in the calculation.

[0261] 2.2 The parameter CSSFwithin_gap introduced in the L1 measurement delay requirement that requires measurement interval needs to clarify the counting range. Based on network indication or UE judgment, the UE may not perform specific L1 mobility measurements that do not require measurement interval (or only perform part of the L1 mobility measurements that do not require measurement interval). The derivation of the CSSF parameter does not consider this type of L1-RSRP that stops measurement.

[0262] For example, when deriving the carrier-specific scaling factor (CSSFwithin_gap) within the measurement gap, dropped inter / intra-frequency L1-RSRP measurements with measurement gaps that have been stopped will not be included in the calculation.

[0263] In some embodiments, when the UE performs only L3 mobility measurement, it does not perform L1-RSRP measurement of the LTM cell under test (stops all L1 measurements):

[0264] 1. For measurements that do not require a measurement interval (same frequency, different frequency, or different system):

[0265] 1.1. No L3 measurement delay requirement for measurement intervals is needed, so there is no impact;

[0266] 1.2. In the L1 measurement delay requirement that does not require a measurement interval, based on network indication or UE judgment, the UE may not perform L1 mobility measurement that does not require a measurement interval;

[0267] 2. For measurements that require measurement intervals (same frequency, different frequency, or different system)

[0268] 2.1 The parameter CSSFwithin_gap introduced in the L3 measurement delay requirement requiring measurement intervals needs clarification regarding its counting range. For measurements requiring measurement intervals, CSSF counts the number of target frequency points for which measurements are performed during the required measurement intervals, including both L1 and L3 mobility measurements. Based on network indications or UE judgment, the UE may choose not to perform specific L1 mobility measurements that do not require measurement intervals (or only perform a portion of the L1 mobility measurements that do not require measurement intervals). The derivation of the CSSF parameter does not consider these types of L1-RSRPs where measurements are stopped.

[0269] For example, when deriving the carrier-specific scaling factor (CSSFwithin_gap) within the measurement gap, dropped inter / intra-frequency L1-RSRP measurements with measurement gaps that have been stopped will not be included in the calculation.

[0270] 2.2 The parameter CSSFwithin_gap introduced in the L1 measurement delay requirement that requires measurement interval needs to clarify the counting range. Based on network indication or UE judgment, the UE may not perform specific L1 mobility measurements that do not require measurement interval (or only perform part of the L1 mobility measurements that do not require measurement interval). The derivation of the CSSF parameter does not consider this type of L1-RSRP that stops measurement.

[0271] For example, when deriving the carrier-specific scaling factor (CSSFwithin_gap) within the measurement gap, dropped inter / intra-frequency L1-RSRP measurements with measurement gaps that have been stopped will not be included in the calculation.

[0272] In some embodiments, the UE stops measuring all or part of the L1 cells under test, if the network requires reporting the measurement results of all or part of the cells under test:

[0273] 1. Based on new UE capabilities:

[0274] 1.1. The UE calculates the L1-RSRP result (one value) based on the obtained L3 measurement results and reports the result;

[0275] 1.2. The UE calculates the L1-RSRP range (a data range) based on the obtained L3 measurement results and reports the range / the maximum value / the minimum value of the range;

[0276] 2. Report agreed-upon values, such as the minimum value supported by signaling, or specific values.

[0277] Figure 2E shows a flowchart of a mobility operation, which includes the following steps:

[0278] Step S251: The UE periodically performs L3 measurements and obtains the L3 measurement results;

[0279] Step S252: The UE evaluation satisfies the L1 measurement conditions (including the first condition); if satisfied, proceed to step S253; if not satisfied, proceed to step S254.

[0280] Step S253: The UE performs L1-RSRP measurement for the corresponding cell;

[0281] Step S254: The UE does not perform L1-RSRP measurement for the corresponding cell, but only performs L3-RSRP measurement;

[0282] Step S255: The network requests the reporting of the L1-RSRP measurement results for this cell;

[0283] Step S256: The UE calculates the corresponding L1-RSRP measurement result and / or the range of the measurement result based on the measured L3-RSRP result;

[0284] Step S257: The UE reports the L1-RSRP measurement results (third information) based on the reporting configuration.

[0285] In some embodiments, based on network configuration, the configuration information may include L3 mobility-related configuration, LTM-related configuration, and / or indication signaling (trigger condition information), and the UE stops / starts specific L1 measurements under certain conditions (first condition) based on network configuration.

[0286] In some embodiments, indication signaling can be used to indicate whether the UE is allowed to perform condition-based mobility measurement on or off. The indication signaling can distinguish whether the mobility measurement refers to L1 mobility measurement or L3 mobility measurement. The signaling indication may include the following information:

[0287] A Boolean value (first indication) indicating whether the UE is allowed to perform condition-based mobility measurements on or off;

[0288] Threshold value;

[0289] Hysteresis value: L3 measurement result plus / minus hysteresis value and comparison with threshold;

[0290] Trigger time information: The L3 measurement results (plus / minus the hysteresis value) are all less than / greater than the threshold value within the trigger time.

[0291] In some embodiments, certain conditions (the activation condition (second triggering condition) is described in reverse) may include:

[0292] Stop condition (first trigger condition): The L3 measurement result of the serving cell / neighboring cell is greater than the threshold value;

[0293] Stop condition: The L3 measurement result of the best beam (worst beam) of the serving cell is greater than the threshold value;

[0294] Stop condition: The L3 measurement result of the neighboring cell is greater than the L3 measurement result of the serving cell.

[0295] In some embodiments, the UE, based on the network-side configuration, begins evaluating the execution conditions for condition-triggered L1 mobility measurement to be turned off / on. If the UE meets the stop condition, the UE stops L1 mobility measurement; if the UE meets the enable condition, the UE starts L1 mobility measurement.

[0296] In some embodiments, the specific L1 measurement mentioned above represents the range within which L1 measurements can be stopped:

[0297] Cell-level evaluation: The UE determines the frequency of the target L1 cell and evaluates whether the L3 measurement results of each cell on that frequency meet the conditions to determine whether to enable L1-RSRP measurement for the target cell; or,

[0298] Frequency-level granularity evaluation: The UE evaluates whether the best L3 measurement results of the cell on the L1 target cell meet the conditions based on the frequency of the L1 target cell, in order to determine whether to enable L1-RSRP measurement for all cells on the frequency.

[0319] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions.
