[0033] Figure 1 An exemplary network environment 100 is shown according to some embodiments. Specifically, the network environment 100 shows a user equipment (UE) 102 that may be in a high-speed scenario (which may also be referred to as a "high-speed train (HST) scenario"). The UE 102 may include a UE 1500 ( Fig.15 )'s features.
[0034] In a high-speed train scenario, the measurement requirements are different from traditional radio resource management (RRM) measurements because the UE mobility scenario is quite special, for example, the mobile speed can be as high as 500 kilometers per hour (km / h). For example, UE 102 may have different measurement requirements from traditional measurements because UE 102 is moving at a high speed (as indicated by arrow 104), such as 500km / h. A threshold speed may be defined for a high-speed mode, where a UE traveling at a speed faster than the threshold speed may be configured for the high-speed mode. In response to determining that UE 102 is traveling faster than the threshold speed, UE 102 may be configured to operate according to the characteristics of the high-speed mode.
[0035] The characteristics of the high-speed mode can solve problems that may be caused by the high-speed travel of the UE 102, such as improper connection and disconnection with the cell / base station of the radio access network (RAN) in which the UE 102 is operating. For example, in the illustrated embodiment, the network environment 100 includes a first base station 106 having a first cell 108, a second base station 110 having a second cell 112, and a third base station 114 having a third cell 116. The first base station 106, the second base station 110, and the third base station 114 may include a next-generation node B (gNB) 1600 ( Fig.16) features. When the UE 102 is traveling in the cell at high speed, when the UE 102 will connect to which of the first base station 106, the second base station 110, and the third base station 114 may be a problem that is not solved by traditional RRM measurements. If the UE 102 incorrectly determines the correct base station to connect to, there is a risk that the UE 102 may lose service. When the base stations 106, 110, and 114 are provided by different vendors with different radio access technologies (RATs), etc., selecting an appropriate base station may be particularly challenging. The UE 102 may operate in a high-speed mode with relevant characteristics to solve this problem. Although three base stations and three cells are shown in the network environment 100 for simplicity, it should be understood that there may be more or fewer base stations and cells in other embodiments.
[0036] Figure 2 2 shows an exemplary measurement period table 200 according to some embodiments. Specifically, table 200 may provide a measurement period (frequency range 1 (FR1)) when configured for high speed RRM enhancement. When a UE (such as UE 102 ( Figure 1 ))When operating in high-speed mode, the measurement period provided may be based on the measurement period used for same-frequency measurements of conventional RAN methods.
[0037] In the traditional method, some enhancements have been made for co-frequency measurements, however, there are still some missing parts that can be further enhanced to improve UE mobility and throughput performance. In the co-frequency design with measurement gaps (MG) in the traditional technical specification (TS) 38.133, as specified in Table 200 (3GPP Organization Partner. 2020-09 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; NR; Requirements for Supporting Radio Resource Management (3GPP TS38.133V16.5.0)). Table 200 is a co-frequency with measurement gaps (MG) and then with a measurement gap repetition period (MGRP). Specifically, the measurement period (T can be determined based on MGRP, a synchronization signal / physical broadcast channel-based measurement time configuration (SMTC) period, the size of a discontinuous reception (DRX) cycle, or some combination thereof based on the size of the DRX cycle or the absence of a DRX cycle. SSB_measurement_period_intra ).
[0038] For example, the T of a UE without DRX cycle is SSB_measurement_period_intra It can be determined by the formula max(200ms,5×max(MGRP,SMTC period)). If different SMTC periods are configured for different cells, the SMTC period in the requirement is the period used by the cell being identified. T for UEs with a DRX cycle less than or equal to 160ms SSB_measurement_period_intraIt can be determined by the formula max(200ms,ceil(M2×5)×max(MGRP,SMTC cycle,DRX cycle)), where M2 is equal to 1.5 if the SMTC cycle is greater than 40ms, otherwise M2 is equal to 1. T of UE with DRX cycle greater than 160ms and less than 320ms SSB_measurement_period_intra It can be determined by the formula max(200ms,ceil(M2×4)×max(MGRP,DRX cycle)), where M2 is equal to 1.5 if the SMTC period is greater than 40ms, otherwise M2 is equal to 1. T of UE with DRX cycle greater than 320ms SSB_measurement_period_intra It can be determined by the formula Y×max(MGRP,DRX cycle), where Y is equal to 3 when SMTC is less than or equal to 40 ms, or Y is equal to 5 when SMTC is greater than 40 ms.
[0039] for Figure 2 , intra-frequency measurement has not considered any resource sharing with other measurement objects so far (i.e., there is no carrier specific scaling factor (CSSF) in Table 200). In Release 16 (R16) (3GPP Organization Partnership. 3rd Generation Partnership Project; Technical Specification Group Radio Access Network. (Release 16)) High Speed Train (HST), the UE only supports a single serving CC, so only one intra-frequency measurement object (MO) will be configured for the UE, but this does not mean that the inter-frequency MO cannot use measurement resources.
[0040] In R16 HST, carrier aggregation (CA) is not considered for HST UEs, but when from Release 17 (R17) (3GPP Organization Partnership. 3rd Generation Partnership Project; Technical Specification Group Radio Access Network. (Release 17)), the period in Table 200 may need to be enhanced for UE measurements for FR1 CA cases. In order to adapt to the CA scenario, a cell identification process on a deactivated secondary component carrier (SCC) in FR1 CA, a synchronization signal / physical broadcast channel block (SSB) index reading process on a deactivated SCC in FR1 CA, and / or a measurement process on a deactivated SCC in FR1 CA may be considered for the periodicity. For the cell identification process on a deactivated SCC in FR1 CA, the number of samples on the deactivated SCC for a specific measCycleSCell may be considered. For the SSB index reading process on a deactivated SCC in FR1 CA, the number of samples on the deactivated SCC for a specific measCycleSCell may be considered. For the measurement process on a deactivated SCC in FR1 CA, consideration may be given to how to use the high-speed flag and measCycleSCell and / or the number of samples on the deactivated SCC for a specific measCycleSCell.
[0041] Although the SSB has been defined as a Synchronization Signal / Physical Broadcast Channel block, it should be understood that in some cases, the SSB may be abbreviated as a Synchronization Signal block. Since the synchronization signal and the physical broadcast channel are packed in a single block, the synchronization signal block and the synchronization signal physical broadcast channel block may refer to the same block. Therefore, the synchronization signal / physical broadcast channel block and the synchronization signal block may be used interchangeably.
[0042] Figure 3 An exemplary measurement period table 300 according to some embodiments is shown. Specifically, table 300 provides the T when configured for high-speed RRM enhancement SSB_measurement_period_intra (frequency range FR1). FR1 may correspond to a frequency range of 410 megahertz (MHz) to 7125 MHz.
[0043] As shown in the table, T SSB_measurement_period_intra can be determined based on the size of the SMTC period and / or the DRX cycle, based on the size of the DRX cycle or the absence of the DRX cycle. For example, the T of a UE without a DRX cycle SSB_measurement_period_intra can be determined by the formula max(200 ms, ceil(5 × K p ) × SMTC period), where K p equals 1 when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, or K p equals 1 / (1 - (SMTC period / MGRP)) when the co-frequency SMTC partially overlaps with the measurement gap, where SMTC period < MGRP. If different SMTC periods are configured for different cells, the SMTC period in the requirement is the period used by the positively identified cell. The T of a UE with a DRX cycle less than or equal to 160 ms SSB_measurement_period_intra can be determined by the formula max(200 ms, ceil(5 × M2 × K p ) × max(SMTC period, DRX cycle)), where M2 equals 1.5 if the SMTC period is greater than 40 ms, otherwise M2 equals 1, and where K p equals 1 when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, or K p equals 1 / (1 - (SMTC period / MGRP)) when the co-frequency SMTC partially overlaps with the measurement gap, where SMTC period < MGRP. The T of a UE with a DRX cycle greater than 160 ms and less than 320 ms SSB_measurement_period_intra can be determined by the formula ceil(4 × M2 × K p)×max(SMTC cycle, DRX cycle) to determine, where if the SMTC cycle is greater than 40 ms, M2 equals 1.5, otherwise M2 equals 1, and where when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, K p equals 1, or when the co-frequency SMTC partially overlaps with the measurement gap, K p equals 1 / (1 - (SMTC cycle / MGRP)), where the SMTC cycle < MGRP. The T of a UE with a DRX cycle greater than 320 ms SSB_measurement_period_intra can be determined by the formula ceil(Y×K p )×DRX cycle, where Y equals 3 when the SMTC is less than or equal to 40 ms, or Y equals 5 when the SMTC is greater than 40 ms, and where when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, K p equals 1, or when the co-frequency SMTC partially overlaps with the measurement gap, K p equals 1 / (1 - (SMTC cycle / MGRP)), where the SMTC cycle < MGRP.
[0044] In R17 HST, after introducing CA for HST UEs, the measurement resources can be shared among the active SCCs for co-frequency measurements without MG. For example, the UE can share the measurement resources among the active SCCs for co-frequency measurements without MG. In R16, the co-frequency measurements without MG are as Figure 3 defined in. For Figure 3 , even if MG is not used and the high-speed flag is configured, the measurement resources can be shared among the serving CCs, so the CSSF for co-frequency measurements without MG needs to be considered.
[0045] Figure 4 Illustrates an exemplary measurement period table 400 according to some embodiments. Specifically, the table 400 provides the measurement periods (FR1) when the RRM enhancements for high speed are configured. The measurement periods can be used when there is a single serving cell and there is no need to share the measurement resources with other serving SCCs. The measurement periods shown in the table 400 can consider the cell identification process on the deactivated SCC in FR1 CA, the SSB index reading process on FR1 CA, and the measurement process on the deactivated SCC in FR1 CA. For some embodiments, the measurement periods can be used together with the co-frequency measurements with MG in R16 HST.
[0046] In the first option, in R16, the network may configure an inter-frequency MO to the HST UE, and if the UE has an intra-frequency MO with MG, then even when the high speed flag is indicated to the UE, the UE may still share the MG resources with the configured inter-frequency MO. The measurement period for intra-frequency measurement with MG may be as follows: Figure 4 CSSF intra is the scaling factor of the measurement period for intra-frequency measurements with MG to share MG resources with configured inter-frequency MO. For example, since only one intra-frequency layer is supported in R16 and the UE has MG sharing factor between intra-frequency and inter-frequency, in this case CSSF intra =K intra (K intra The definition is the same as in Section 9.1.2.1a of TS38.133). Specifically, K intra It can be equal to 1 / X×100, where X depends on the measurement gap sharing scheme (measGapSharingScheme) that allocates measurement resources between inter-frequency measurement and intra-frequency measurement. intra The measurement period provided by Table 300 can take CSSF into account when determining the measurement period. intra .
[0047] For example, the T of a UE without DRX cycle is SSB_measurement_period_intra It can be calculated by the formula max(200ms,5×max(MGRP,SMTC period))×CSSF intra If different SMTC periods are configured for different cells, the SMTC period in the requirement is the period used by the cell being identified. T for UEs with a DRX cycle less than or equal to 160ms SSB_measurement_period_intra It can be calculated by the formula max(200ms,ceil(M2×5)×max(MGRP,SMTC period,DRX cycle))×CSSF intra is determined by, where if the SMTC period is greater than 40ms, M2 is equal to 1.5, otherwise M2 is equal to 1. The T of the UE with a DRX cycle greater than 160ms and less than 320ms SSB_measurement_period_intra It can be calculated by the formula max(200ms,ceil(M2×4)×max(MGRP,DRX cycle)×CSSF intra is determined by, where if the SMTC period is greater than 40ms, M2 is equal to 1.5, otherwise M2 is equal to 1. The T of the UE with a DRX cycle greater than 320ms SSB_measurement_period_intra It can be obtained by the formula Y×max(MGRP,DRX cycle)×CSSF intrato determine, where Y is equal to 3 when SMTC is less than or equal to 40ms, or Y is equal to 5 when SMTC is greater than 40ms.
[0048] Consider CSSF when determining the measurement period intra Scaling of the measurement period for intra-frequency measurements with MG may be provided to share MG resources with configured inter-frequency MOs. For example, the measurement period may take into account other inter-frequency layers for neighbor cell measurements. In some of these embodiments, the UE may have a single serving cell, but may be configured with different neighbor cells on different frequency layers. The measurement period may be used for measurements associated with one or more neighbor cells on different frequency layers.
[0049] Figure 5 A method for implementing Figure 4 5. An exemplary process 500 for measuring a period of time for a UE (such as UE 102 ( Figure 1 )) can be based on the measurement period shown in Table 400 ( Figure 4 ) to implement the process for performing the measurement.
[0050] Process 500 may include determining, at 502, that the UE is in a high speed scenario. For example, the UE may determine whether the UE is in a high speed scenario in the RAN. The UE may determine whether the UE is in a high speed scenario based on a value of a high speed flag of the UE, wherein if it is determined that the UE is traveling at a speed greater than a threshold speed value associated with the HST, the high speed flag may indicate that the UE is in a high speed scenario, and if it is determined that the UE is traveling at a speed less than the threshold speed value, the high speed flag may indicate that the UE is not in a high speed scenario. The base station may indicate the value of the high speed flag to the UE.
[0051] Process 500 may include receiving an intra-frequency MO to configure intra-frequency measurement with MG resources in 504. For example, the UE may receive an intra-frequency MO from a base station. The base station may operate a primary cell for the UE. The UE may utilize the intra-frequency MO to configure intra-frequency measurement with MG resources. In some embodiments, 504 may be omitted.
[0052] Process 500 may include receiving one or more inter-frequency MOs to configure one or more inter-frequency measurements in 506. For example, the UE may receive one or more inter-frequency MOs from a base station. The UE may utilize the one or more inter-frequency MOs to configure one or more inter-frequency measurements. In some embodiments, 506 may be omitted.
[0053] Process 500 may include utilizing CSSF at 508. intra To scale MG resources to accommodate one or more inter-frequency measurements. For example, the UE may use CSSF intra to scale the MG resources from the intra-frequency measurement in 504. In some implementations, 508 may be omitted.
[0054] Process 500 may include determining a measurement period at 510. For example, the UE may determine a measurement period for intra-frequency measurement with MG resources. The UE may determine a measurement period based on the CSSF of the high-speed scenario. intra The UE may determine the measurement period according to the measurement period ( Figure 4 ) to determine the measurement period. Specifically, the UE may determine the measurement period using one of the formulas in Table 400, wherein the formula used may correspond to the size of the DRX cycle of the UE. The measurement period may be an SSB measurement period.
[0055] Process 500 may include initiating intra-frequency measurements at 512. For example, the UE may initiate intra-frequency measurements to be performed during a measurement period. The intra-frequency measurements may include SSB measurements.
[0056] Figure 6 A method for implementing Figure 4 The process 600 may be performed by a base station (such as gNB 1600) Fig.16 ))Based on Table 400( Figure 4 ) is performed by the measurement cycle included in ).
[0057] Process 600 may include determining that the UE is in a high-speed scenario at 602. For example, the base station may determine a travel speed of the UE. The base station may compare the travel speed with a threshold speed value and determine that the base station is in a high-speed scenario based on the travel speed being greater than the threshold speed value.
[0058] Process 600 may include providing an indication of a high speed scenario to the UE at 604. For example, the base station may provide an indication to the UE that the UE is in a high speed scenario based on the determination of 602.
[0059] Process 600 may include configuring the UE with parameters for determining the measurement period by the UE at 606. For example, the base station may configure the UE with values of the size of the MGRP, SMTC period, and / or DRX cycle for the UE to use in determining the measurement period.
[0060] Process 600 may include providing a same-frequency measurement object at 608. For example, the base station may provide the UE with the same-frequency measurement object at 504 ( Figure 5 ) In some implementations, 608 may be omitted.
[0061] Process 600 may include providing one or more inter-frequency measurement objects at 610. For example, the base station may provide the UE with one or more inter-frequency measurement objects at 506 ( Figure 5 ) In some implementations, 610 may be omitted.
[0062] Process 600 may also include determining a measurement period for the UE at 612. For example, the base station may determine the measurement period according to the measurement period provided in table 400. The measurement period determined by the base station may be a period used by the UE to measure the measurement period according to process 500 ( Figure 5 ) performs the measurement cycle of the same frequency measurement.
[0063] Process 600 may also include starting a timer at 614. For example, the base station may start an internal timer based on the measurement period determined at 612. The internal timer may allow the base station to be aware of the UE's timer.
[0064] In the second option of intra-frequency measurement with MG in R16 HST, in R16, the network may avoid configuring inter-frequency MO to HST UE, and the UE may only need to measure one intra-frequency MO with or without MG. All measurement cycles in TS 38.133 are applicable to R16 HST UE only when the above network (NW) restrictions apply. In this option, the base station may avoid configuring inter-frequency MO to UE in high-speed mode. The UE may measure a single intra-frequency MO with or without MG.
[0065] Figure 7 An exemplary time period table 700 according to some embodiments is shown. Specifically, table 700 provides a time period (FR1) for primary synchronization signal (PSS) / secondary synchronization signal (SSS) detection, deactivation of a secondary cell (SCell). The time period can be used for PSS / SSS detection in R17 HST in FR1 CA. The table 700 shown is an existing table in legacy TS 38.133, and it can be updated for enhancements as indicated herein.
[0066] If the HST UE operates in NR CA, or the HST UE uses measCycleSCell (measCycleSCell is the measurement period of the deactivated SCC) to measure the deactivated SCC, the corresponding identification or measurement delay can be updated from the traditional time period. For the cell identification on the deactivated SCC, some updates / enhancements can be made based on the traditional PSS / SSS detection period of the deactivated SCC.
[0067] Table 700 shows a time period for PSS / SSS detection according to a conventional implementation of a time period. The time period for PSS / SSS detection may be based on the DRX cycle of the UE. For example, the same-frequency PSS / SSS detection time period (T PSS / SSS_sync_intra ) can be obtained by the formula 5×measCycleSCell×CSSF intra The T of the UE with a DRX cycle less than or equal to 320msPSS / SSS_sync_intra The formula is 5×max(measCycleSCell,1.5×DRX cycle)×CSSF intra The T of the UE with a DRX cycle greater than 320ms PSS / SSS_sync_intra The formula is 5×max(measCycleSCell,DRX cycle)×CSSF intra to be sure.
[0068] The proposed method for PSS / SSS detection in R17 HST in FR1 CA may include updating T PSS / SSS_sync_intra For example, the scaling factor and / or number of samples for layer 1 (L1) filtering may be updated based on conventional values for PSS / SSS detection.
[0069] In some embodiments, the scaling factor 702 for the DRX cycle may be updated within the formula. As can be seen from Table 700, the conventional T PSS / SSS_sync_intra The scaling factor 702 in the calculation may be included for DRX cycles less than or equal to 320 ms and may have a value of 1.5. In a first option, for HST, the scaling factor 702 of 1.5 when DRX≤320 ms may be removed. Specifically, the scaling factor 702 may be changed to 1, thereby removing the scaling of the DRX cycle value performed by the legacy scaling factor. In a second option, when measCycleSCell>X, X is a predefined threshold (e.g., X=320 ms), the scaling factor 702 of 1.5 when DRX≤320 ms may be applied; otherwise, for HST, the scaling factor 702 of 1.5 when DRX≤320 ms may be removed. Specifically, the scaling factor 702 may be changed to 1 unless the value of measCycleSCell is greater than a predefined threshold X. Therefore, when the value of measCycleSCell is less than or equal to the predefined threshold X, the scaling factor 702 may be changed to 1. In some embodiments, the predefined threshold may be 320 ms. In the case where measCycleSCell is less than a predefined threshold value X, the value of the scaling factor 702 may be 1.5.
[0070] In some implementations, the number of samples for L1 filtering may be updated 704. As can be seen from the table, for no DRX cycle, DRX cycle less than or equal to 320 ms, and DRX cycle greater than 320 ms, the traditional T PSS / SSS_sync_intra The number of samples in the calculation is 704, of which the traditional T PSS / SSS_sync_intra The value of the number of samples 704 in has a value of 5. In a first option, the number of samples 704 for L1 filtering for HST UEs may be reduced to less than 5.
[0071] In a second option, the number of samples 704 may be determined based on different measCycleSCells, and different measCycleSCells may require different numbers of samples, and these enhanced numbers of samples may be equal to or less than 5. For example, the number of samples 704 may be determined based on the value of measCycleSCell, wherein the determined value may be less than or equal to 5. A larger measCycleSCell may have more number of samples. Specifically, the number of samples 704 may be proportional to the measCycleSCell, wherein a larger measCycleSCell corresponds to a larger number of samples, and a smaller measCycleSCell corresponds to a smaller number of samples.
[0072] In a third option, the number of samples 704 may be determined based on different DRX cycles, and different DRX cycles may require different numbers of samples, and these enhanced numbers of samples may be equal to or less than 5. For example, the number of samples 704 may be determined based on the size of the DRX cycle, where the determined value may be less than or equal to 5. A larger DRX cycle may have a smaller number of samples. Specifically, the number of samples 704 may be inversely proportional to the size of the DRX cycle, where a larger DRX cycle corresponds to a smaller number of samples, and a smaller DRX cycle corresponds to a larger number of samples.
[0073] In a fourth option, the number of samples 704 may be determined based on different max(measCycleSCell,DRX cycle) values, and different max(measCycleSCell,DRX cycle) values may require different numbers of samples, and if DRX>320ms, those enhanced numbers of samples may be equal to or less than 5. For example, when the DRX cycle is greater than 320ms and the scaling factor 702 is 1, the number of samples 704 may be determined based on the maximum value of measCycleSCell or the DRX cycle. The number of samples 704 may be determined based on different max(measCycleSCell,1.5*DRX cycle) values, and different max(measCycleSCell,1.5*DRX cycle) values may require different numbers of samples, and if DRX<=320 and if the scaling factor 702 is 1.5, those enhanced numbers of samples may be equal to or less than 5. For example, when the DRX cycle is less than or equal to 320 ms and the scaling factor 702 is 1.5, the number of samples 704 may be determined based on the maximum value of measCycleSCell or 1.5 times the DRX cycle. When measCycleSCell is utilized, the number of samples 704 may be proportional to measCycleSCell, and when the DRX cycle is utilized, the number of samples may be inversely proportional to the size of the DRX cycle.
[0074] Figure 8An exemplary time period table 800 according to some embodiments is shown. Specifically, table 800 provides a time period (FR1) for time index detection, deactivated SCell. This time period can be used for SSB index detection in R17 HST in FR1 CA. The table 800 shown is an existing table in legacy TS 38.133, and it can be updated for enhancements as indicated herein.
[0075] If the HST UE operates in NR CA, or the HST UE uses measCycleSCell (measCycleSCell is the measurement period of the deactivated SCC) to measure the deactivated SCC, the corresponding identifier or measurement delay can be updated from the traditional time period. For time index detection on the deactivated SCC, some updates / enhancements can be made based on the traditional time index detection period of the deactivated SCC.
[0076] Table 800 shows a time period for SSB index detection according to a conventional implementation of a time period. The time period for SSB index detection may be based on the DRX cycle of the UE. For example, the same-frequency SSB index detection time period (T SSB_time_index_intra ) can be obtained by the formula 3×measCycleSCell×CSSF intra The T of the UE with a DRX cycle less than or equal to 320ms SSB_time_index_intra The formula is 3×max(measCycleSCell,1.5×DRX cycle)×CSSF intra The T of the UE with a DRX cycle greater than 320ms SSB_time_index_intra The formula is 3×max(measCycleSCell,DRX cycle)×CSSF intra to be sure.
[0077] The proposed method for SSB index detection in R17 HST in FR1 CA may include updating T SSB_time_index_intra For example, the scaling factor and / or number of samples for L1 filtering may be updated based on conventional values for SSB index detection.
[0078] In some embodiments, the scaling factor 802 for the DRX cycle may be updated within the formula. As can be seen from Table 800, the conventional T SSB_time_index_intraThe scaling factor 802 in the calculation may be included for DRX cycles less than or equal to 320 ms and may have a value of 1.5. In a first option, for HST, the scaling factor 802 of 1.5 when DRX≤320 ms may be removed. Specifically, the scaling factor 802 may be changed to 1, thereby removing the scaling of the DRX cycle value performed by the legacy scaling factor. In a second option, when measCycleSCell>X, X is a predefined threshold (e.g., X=320 ms), the scaling factor 802 of 1.5 when DRX≤320 ms may be applied; otherwise, for HST, the scaling factor 802 of 1.5 when DRX≤320 ms may be removed. Specifically, the scaling factor 802 may be changed to 1 unless the value of measCycleSCell is greater than a predefined threshold X. Therefore, when the value of measCycleSCell is less than or equal to a predefined threshold X, the scaling factor 802 may be changed to 1. In some embodiments, the threshold may be 320 ms. In the case where measCycleSCell is less than a predefined threshold value X, the value of the scaling factor 802 may be 1.5.
[0079] In some implementations, the number of samples for L1 filtering 804 may be updated. As can be seen from the table, for no DRX cycle, DRX cycle less than or equal to 320 ms, and DRX cycle greater than 320 ms, the traditional T SSB_time_index_intra The number of samples in the calculation is 804, of which the traditional T SSB_time_index_intra The value of the number of samples 804 in has a value of 3. In a first option, the number of samples 804 for L1 filtering for HST UEs may be reduced to less than 3.
[0080] In a second option, the number of samples 804 may be determined based on different measCycleSCells, and different measCycleSCells may require different numbers of samples, and these enhanced numbers of samples may be equal to or less than 3. For example, the number of samples 804 may be determined based on the value of measCycleSCell, wherein the determined value may be less than or equal to 3. A larger measCycleSCell may have more number of samples. Specifically, the number of samples 804 may be proportional to the measCycleSCell, wherein a larger measCycleSCell corresponds to a larger number of samples, and a smaller measCycleSCell corresponds to a smaller number of samples.
[0081] In a third option, the number of samples 804 may be determined based on different DRX cycles, and different DRX cycles may require different numbers of samples, and these enhanced numbers of samples may be equal to or less than 3. For example, the number of samples 804 may be determined based on the size of the DRX cycle, where the determined value may be less than or equal to 3. A larger DRX cycle may have a smaller number of samples. Specifically, the number of samples 804 may be inversely proportional to the size of the DRX cycle, where a larger DRX cycle corresponds to a smaller number of samples, and a smaller DRX cycle corresponds to a larger number of samples.
[0082] In a fourth option, the number of samples 804 may be determined based on different max(measCycleSCell,DRX cycle) values, and different max(measCycleSCell,DRX cycle) values may require different numbers of samples, and if DRX>320ms, those enhanced numbers of samples may be equal to or less than 3. For example, when the DRX cycle is greater than 320ms and the scaling factor 802 is 1, the number of samples 804 may be determined based on the maximum value of measCycleSCell or the DRX cycle. The number of samples 804 may be determined based on different max(measCycleSCell,1.5*DRX cycle) values, and different max(measCycleSCell,1.5*DRX cycle) values may require different numbers of samples, and if DRX<=320 and if the scaling factor 802 is 1.5, those enhanced numbers of samples may be equal to or less than 3. For example, when the DRX cycle is less than or equal to 320 ms and the scaling factor 802 is 1.5, the number of samples 804 may be determined based on the maximum value of measCycleSCell or 1.5 times the DRX cycle. When measCycleSCell is utilized, the number of samples 804 may be proportional to measCycleSCell, and when the DRX cycle is utilized, the number of samples may be inversely proportional to the size of the DRX cycle.
[0083] Fig. 9 An exemplary measurement period table 900 according to some embodiments is shown. Specifically, table 900 provides a measurement period for a measurement period (FR1) for intra-frequency measurement (deactivated SCell) without gaps. The measurement period can be used to measure a deactivated SCC in R17 HST in FR1 CA. Table 900 shown is an existing table in legacy TS 38.133, and it can be updated for enhancements as indicated herein.
[0084] If the HST UE operates in NR CA, or the HST UE uses measCycleSCell (measCycleSCell is the measurement period of the deactivated SCC) to measure the deactivated SCC, the corresponding identifier or measurement delay can be updated from the traditional time period. For measurements on the deactivated SCC, some updates / enhancements can be made based on the traditional measurement period of the deactivated SCC.
[0085] Table 900 shows a measurement period for measuring a deactivated SCC according to a conventional implementation of a measurement period. The measurement period for measuring a deactivated SCC may be based on a DRX cycle of a UE. For example, the measurement period (T SSB_time_index_intra ) can be obtained by the formula 5×measCycleSCell×CSSF intra The T of the UE with a DRX cycle less than or equal to 320ms SSB_time_index_intra The formula is 5×max(measCycleSCell,1.5×DRX cycle)×CSSF intra The T of the UE with a DRX cycle greater than 320ms SSB_time_index_intra The formula is 5×max(measCycleSCell,DRX cycle)×CSSF intra to be sure.
[0086] The method proposed herein for the measurement period of a deactivated SCC in an R17 HST in an FR1 CA may include updating T SSB_time_index_intra For example, the scaling factor and / or number of samples for L1 filtering may be updated according to conventional values of the measurement period for deactivated SCCs.
[0087] In some embodiments, the scaling factor 902 for the DRX cycle may be updated within the formula. As can be seen from Table 900, the conventional T SSB_time_index_intraThe scaling factor 902 in the calculation may be included for DRX cycles less than or equal to 320 ms and may have a value of 1.5. In a first option, for HST, the scaling factor 902 of 1.5 when DRX≤320 ms may be removed. Specifically, the scaling factor 902 may be changed to 1, thereby removing the scaling of the DRX cycle value performed by the legacy scaling factor. In a second option, when measCycleSCell>X, X is a predefined threshold (e.g., X=320 ms), the scaling factor 902 of 1.5 when DRX≤320 ms may be applied; otherwise, for HST, the scaling factor 902 of 1.5 when DRX≤320 ms may be removed. Specifically, the scaling factor 902 may be changed to 1 unless the value of measCycleSCell is greater than a predefined threshold X. Therefore, when the value of measCycleSCell is less than or equal to a predefined threshold X, the scaling factor 902 may be changed to 1. In some embodiments, the threshold may be 320 ms. In the case where measCycleSCell is less than a predefined threshold value X, the value of the scaling factor 902 may be 1.5.
[0088] In some implementations, the number of samples for L1 filtering 904 may be updated. As can be seen from the table, for no DRX cycle, DRX cycle less than or equal to 320 ms, and DRX cycle greater than 320 ms, the traditional T SSB_time_index_intra The number of samples in the calculation is 904, of which the traditional T SSB_time_index_intra The value of the number of samples 904 in has a value of 5. In a first option, the number of samples 904 for L1 filtering for HST UEs may be reduced to less than 5.
[0089] In a second option, the number of samples 904 may be determined based on different measCycleSCells, and different measCycleSCells may require different numbers of samples, and these enhanced numbers of samples may be equal to or less than 5. For example, the number of samples 904 may be determined based on the value of measCycleSCell, wherein the determined value may be less than or equal to 5. A larger measCycleSCell may have more number of samples. Specifically, the number of samples 904 may be proportional to the measCycleSCell, wherein a larger measCycleSCell corresponds to a larger number of samples, and a smaller measCycleSCell corresponds to a smaller number of samples.
[0090] In a third option, the number of samples 904 may be determined based on different DRX cycles, and different DRX cycles may require different numbers of samples, and these enhanced numbers of samples may be equal to or less than 5. For example, the number of samples 904 may be determined based on the size of the DRX cycle, where the determined value may be less than or equal to 5. A larger DRX cycle may have a smaller number of samples. Specifically, the number of samples 904 may be inversely proportional to the size of the DRX cycle, where a larger DRX cycle corresponds to a smaller number of samples, and a smaller DRX cycle corresponds to a larger number of samples.
[0091] In a fourth option, the number of samples 904 may be determined based on different max(measCycleSCell,DRX cycle) values, and different max(measCycleSCell,DRX cycle) values may require different numbers of samples, and if DRX>320ms, those enhanced numbers of samples may be equal to or less than 5. For example, when the DRX cycle is greater than 320ms and the scaling factor 902 is 1, the number of samples 904 may be determined based on the maximum value of measCycleSCell or the DRX cycle. The number of samples 904 may be determined based on different max(measCycleSCell,1.5*DRX cycle) values, and different max(measCycleSCell,1.5*DRX cycle) values may require different numbers of samples, and if DRX<=320 and if the scaling factor 902 is 1.5, those enhanced numbers of samples may be equal to or less than 5. For example, when the DRX cycle is less than or equal to 320 ms and the scaling factor 802 is 1.5, the number of samples 904 may be determined based on the maximum value of measCycleSCell or 1.5 times the DRX cycle. When measCycleSCell is utilized, the number of samples 904 may be proportional to measCycleSCell, and when the DRX cycle is utilized, the number of samples may be inversely proportional to the size of the DRX cycle.

[0095] Process 1000 may include determining a period for performing an operation in 1006. For example, the UE may determine a period for PSS / SSS detection, SSB index detection, or measurement of a deactivated SCC based on the operation determined in 1004. The period may be a time period (such as in the case of PSS / SSS detection or SSB index detection of a deactivated SCC) or a measurement period (such as in the case of measurement of a deactivated SCC). In the case of PSS / SSS detection of a deactivated SCC, the period may be determined according to a time period calculation provided in table 700, the time period calculation having a scaling factor for DRX cycle update and / or a number of samples for L1 filtering update, as described with respect to table 700. In the case of SSB index detection of a deactivated SCC, the period may be determined according to a time period calculation provided in table 800, the time period calculation having a scaling factor for DRX cycle update and / or a number of samples for L1 filtering update, as described with respect to table 800. In case of gapless intra-frequency measurement of a deactivated SCC, the period may be determined according to the measurement period calculation provided in table 900 with a scaling factor for DRX cycle update and / or a number of samples for L1 filtering update as described with respect to table 900.
[0096] Process 1000 may include performing an operation at 1008. For example, the UE may perform a PSS / SSS detection operation, an SSB index detection operation, or a gapless intra-frequency measurement operation for a deactivated SCC as determined at 1004. The UE may perform the operation using the time period or measurement period determined at 1006.
[0097] Fig.11 An exemplary process 1100 is shown according to some embodiments. Figure 1 Base station or gNB 1600( Fig.16 )) The process 1100 may be performed to perform operations by a UE connected to a base station. The operations may be related to Figures 7 to 9 One of the operations described in any one of the above, and the time period or measurement period is based on Figures 7 to 9 For example, the operation may include performing PSS / SSS detection, performing SSB index detection, or performing measurements in R17 HST in FR1 CA.

[0098] Process 1100 may include determining that the UE is in high speed mode at 1102. For example, the base station may determine that the UE is connected to the base station in high speed mode in FR CA. The base station may determine that the UE is in high speed mode by determining a travel speed of the UE and determining that the travel speed of the UE exceeds a threshold travel speed corresponding to the high speed mode.

The operation may include one of PSS / SSS detection, SSB index detection, or gapless intra-frequency measurement on the deactivated SCC, such as respectively Figures 7 to 9 as described.
[0100] The process 1100 may include determining a period for performing an operation in 1106. For example, the base station may determine a period for PSS / SSS detection, SSB index detection, or measurement of a deactivated SCC based on the operation determined in 1104. The period may be a time period (such as in the case of PSS / SSS detection or SSB index detection of a deactivated SCC) or a measurement period (such as in the case of measurement of a deactivated SCC). In the case of PSS / SSS detection of a deactivated SCC, the period may be determined according to the time period calculation provided in Table 700, the time period calculation having a scaling factor for DRX cycle update and / or a number of samples for L1 filtering update, as described with respect to Table 700. In the case of SSB index detection of a deactivated SCC, the period may be determined according to the time period calculation provided in Table 800, the time period calculation having a scaling factor for DRX cycle update and / or a number of samples for L1 filtering update, as described with respect to Table 800.

[0101] Process 1100 may include starting a timer at 1108. For example, the base station may start an internal timer according to the period determined at 1106. The internal timer may provide the base station with knowledge of the UE's timer being used for operation and / or operation progress.
[0102] Fig.12 1 shows an exemplary measurement period table 1200 according to some embodiments. Specifically, table 1200 provides a measurement period for R17 co-frequency measurement without MG for HST. The measurement period may be an SSB measurement period (T SSB_measurement_period_intra ).
[0103] In R17 HST, after CA is introduced for HST UEs, measurement resources may be shared between activated SCCs for intra-frequency measurement without MG even when the high speed flag is indicated to the UE. For example, when the high speed flag indicates that the UE is in high speed mode, measurement resources (which may be referred to as searcher resources in some cases where the measurement resources are in baseband) may be shared by the UE between active serving CCs for intra-frequency measurement without MG. The measurement period for intra-frequency measurement without MG may also be as follows: Fig.12 For example, the measurement period for the same-frequency measurement without the MG may be determined according to the calculation provided in Table 1200.
[0104] The measurement period provided by Table 1200 can take CSSF into account when determining the measurement period.intra In addition, the calculation of the measurement period may depend on the DRX cycle of the HST UE that performs co-frequency measurements without MG. For example, the T of a UE without a DRX cycle SSB_measurement_period_intra can be determined by the formula max(200 ms, ceil(5 × K p ) × SMTC period) × CSSF intra , where K is equal to 1 when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, or K p is equal to 1 / (1 - (SMTC period / MGRP)) when the co-frequency SMTC partially overlaps with the measurement gap, where the SMTC period < MGRP. If different SMTC periods are configured for different cells, the SMTC period in the requirement is the period used by the positively identified cell. The T of a UE with a DRX cycle less than or equal to 160 ms p can be determined by the formula max(200 ms, ceil(5 × M2 × K SSB_measurement_period_intra ) × max(SMTC period, DRX cycle)) × CSSF p , where M2 is equal to 1.5 if the SMTC period is greater than 40 ms, otherwise M2 is equal to 1, and where K is equal to 1 when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, or K intra is equal to 1 / (1 - (SMTC period / MGRP)) when the co-frequency SMTC partially overlaps with the measurement gap, where the SMTC period < MGRP. The T of a UE with a DRX cycle greater than 160 ms and less than 320 ms p can be determined by the formula ceil(4 × M2 × K p ) × max(SMTC period, DRX cycle) × CSSF SSB_measurement_period_intra , where M2 is equal to 1.5 if the SMTC period is greater than 40 ms, otherwise M2 is equal to 1, and where K is equal to 1 when the co-frequency SMTC does not overlap with the measurement gap at all or the co-frequency SMTC completely overlaps with the MG, or K p is equal to 1 / (1 - (SMTC period / MGRP)) when the co-frequency SMTC partially overlaps with the measurement gap, where the SMTC period < MGRP. The T of a UE with a DRX cycle greater than 320 ms intra can be determined by the formula ceil(Y × K p ) × DRX cycle × CSSF p , where Y is a certain value (not specified in the original text). SSB_measurement_period_intra can be determined by the formula ceil(Y × K p ) × DRX cycle × CSSF intrais determined by, where Y is equal to 3 when SMTC is less than or equal to 40 ms, and Y is equal to 5 when SMTC is greater than 40 ms, and where K is equal to p is equal to 1, or when the same-frequency SMTC partially overlaps with the measurement gap, K p Equal to 1 / (1-(SMTC period / MGRP)), where SMTC period <MGRP。
[0105] CSSF intra is the scaling factor of the measurement period for intra-frequency measurements without MG to share searcher resources between active serving CCs. For example, for HST PCC, “CSSF intra = 1", and for each HST SCC in the CA, "CSSF intra = Number of HST SCCs. For example, CSSF intra To scale the measurement period for intra-frequency measurements without MG, where the UE is sharing searcher resources between active serving CCs. For HST primary component carrier (PCC) measurements, CSSF intra In the formula shown in table 1200, may be equal to 1, and for HST SCC measurements may be equal to the number of HST SCCs.
[0106] Fig.13 An exemplary process 1300 according to some embodiments is shown. Specifically, the process 1300 may be used for R17 intra-frequency measurement without MG for HST. A UE (such as UE 102 ( Figure 1 ))Process 1300 may be performed to perform same-frequency measurements without MG for HST.
[0107] Process 1300 may include determining that the UE is in high speed mode at 1302. For example, the UE may determine that the UE is connected to a base station in high speed mode in CA. The UE may determine that the UE is in high speed mode based on a high speed flag indicated to the UE.
[0108] Process 1300 may include determining, at 1304, a CSSF for a measurement period. intra For example, the UE may determine the CSSF for the measurement period for intra-frequency measurement without the MG. intra In the case of intra-frequency measurements for HST PCC, the UE can determine the CSSF intra =1, and in the case where the intra-frequency measurement is for an HST SCC, the UE may determine the CSSF intra Equal to the number of HST SCCs.
[0109] Process 1300 may include determining a measurement period at 1306. For example, the UE may determine a measurement period for intra-frequency measurement without the MG. intra To determine the measurement period. Specifically, according to Table 1200 ( Fig.12 ) is used to determine the measurement period, where CSSF intra is the value determined in 1304 .
[0110] Process 1300 may include configuring a measurement period and sharing searcher resources at 1308.

For example, if the platform UE is in the RRC_Connected state, in which the platform is still connected to the RAN node because it expects to receive traffic soon, then after a period of inactivity, the platform may enter a state known as discontinuous reception mode (DRX). During this state, the UE 1500 may be powered off for short time intervals, thereby saving power. If there is no data traffic activity for an extended period of time, the UE 1500 may transition to the RRC_Idle state, in which the device is disconnected from the network and no operations such as channel quality feedback, handovers, etc. are performed. The UE 1500 enters a very low power state and performs paging, in which the device wakes up periodically again to listen to the network and then powers off again. The UE 1500 may not receive data in this state; in order to receive data, the platform must transition back to the RRC_Connected state. Additional power saving modes may prevent the device from using the network for longer than the paging interval (ranging from a few seconds to several hours). During this time, the device is completely unable to connect to the network and can be completely powered off. Any data sent during this time will be significantly delayed, and it is assumed that the delay is acceptable.
