[0002] This application claims priority to Chinese Patent Application No. 202510133919.6, filed on February 6, 2025, entitled "Measurement Method, Electronic Device, Readable Storage Medium and Computer Program Product under Multi-Carrier Switching", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to a measurement method, electronic device, readable storage medium, and computer program product under multi-carrier switching. Background Technology

[0004] To support wireless signal coverage across different frequency bands, base stations and terminals deploy multiple antennas to cover low-frequency, mid-frequency, and high-frequency wireless signal reception and transmission. Different types of antennas have varying bandwidth coverage capabilities, which can be described using fractional bandwidth to describe the antenna's performance stability at different frequencies. Regardless of the antenna type, there is a trade-off between antenna gain and fractional bandwidth. High-gain antennas tend to be designed with narrower antennas and smaller fractional bandwidths, while wideband antennas often have lower antenna gain because better radiation characteristics in a specific direction limit the bandwidth.

[0005] To increase network throughput and coverage, the LTE-A system introduces carrier aggregation (CA) technology, allowing user equipment (UE) to operate simultaneously on multiple carriers. By aggregating multiple component carriers (CCs), it supports wider transmission bandwidth. Simultaneously, dual connectivity (DC) allows terminal devices to establish connections with multiple cells or radio access networks at the same time. By combining the resources of multiple cells, it enhances network performance, increases data rates, reduces latency, and improves overall service quality.

[0006] In some CA or DC combinations, due to limitations in antenna size and terminal cost, the same antenna or RF resource may be used for signal transmission and reception across multiple frequency bands or carriers. However, to achieve a certain antenna gain, the antenna fractional bandwidth must not exceed a certain empirical value, thus limiting the antenna radiation bandwidth and potentially preventing it from encompassing multiple component carriers or frequency bands. Therefore, it is necessary to introduce methods such as transmit antenna switching, receive antenna switching, transmit RF resource switching, or receive RF resource switching to enable the same antenna or RF resource to be applied to multiple carriers or frequency bands in a time-division manner.

[0007] Measurements include physical layer measurements for link quality inspection or beam management, and radio resource management (RRM) measurements for mobility management. The former are often short-term measurements, while the latter are typically long-term measurements. Both types of measurements are performed based on a reference signal (RS) configured by the base station for the terminal. When the frequency of the RS to be measured differs from the frequency of the serving cell or serving carrier used for data transmission and reception, the terminal needs to utilize gaps configured by the base station to perform such measurements.

[0008] However, with the introduction of transmit or receive switching between different frequency ranges, it may affect the measurement on a certain carrier or frequency band. For example, it may cause interruptions on gap opportunities, and all uplink and downlink control channels and service channels will be interrupted. Excessive interruptions will further degrade the throughput. Therefore, new methods need to be introduced to solve the measurement problem under transmit or receive switching.

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0023] An exemplary embodiment of this application provides a measurement method under multi-carrier handover, which can be executed by a UE. The main application scenarios and general configurations of this method are as follows, and are applicable to all embodiments herein:

[0024] To increase system throughput, base stations are configured to operate on multiple cells or carriers aggregated in CA or DC modes. Each of these cells or carriers corresponds to a frequency bandwidth, which may or may not overlap. The duplexing mode of these cells or carriers can be Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), Supplementary Downlink (SDL), or Supplementary Uplink (SUL). The duplexing modes of different cells or carriers can be the same or different.

[0025] For example: Cell 1 or carrier 1 is FDD, and Cell 2 or carrier 2 is SDL.

[0026] For example: cell 1 or carrier 1 is FDD, cell 2 or carrier 2 is FDD.

[0027] For example: Cell 1 or carrier 1 is TDD, and cell 2 or carrier 2 is FDD.

[0028] For example: Cell 1 or carrier 1 is TDD, and cell 2 or carrier 2 is SDL.

[0029] For example: Cell 1 or carrier 1 is TDD, and cell 2 or carrier 2 is TDD.

[0030] Figure 1 shows a flowchart of a measurement method under multi-carrier handover provided in an exemplary embodiment of this application. As shown in Figure 1, the measurement method under multi-carrier handover mainly includes the following steps (S110-S130).

[0031] S110, obtain the handover configuration, wherein the handover configuration is the time-division enabling configuration configured by the base station for the terminal.

[0032] In this embodiment, the base station can send handover configuration information for measurement to the UE via Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE), or Downlink Control Information (DCI). This handover configuration is an enable time-division configuration provided by the base station to the terminal, instructing the terminal to perform corresponding transmission operations on different carriers, cells, or frequency bands at different time periods. This handover configuration is carried in the RRC signaling, MAC CE, or DCI. In addition, the base station can also configure measurement configuration information for the terminal, such as the Measurement Object (MO) and measurement gap. Based on the handover configuration information, the UE determines the measurement indicators for different time-division time periods, performs measurements according to the measurement indicators and the measurement configuration information, and then reports the measurement results to the network.

[0033] In some embodiments, the aforementioned time-division period may include: a first time period T1 and a second time period T2; the enabled time-division configuration is used to instruct the terminal to enable transmission operations of the first service frequency band during the first time period T1 and to enable transmission operations of the second service frequency band during the second time period T2; wherein, the first service frequency band includes one of the following: a first carrier, a first cell, and a first frequency band, the second service frequency band includes one of the following: a second carrier, a second cell, and a second frequency band, and the transmission operation includes at least one of the following: a receiving operation and a transmitting operation.

[0034] In specific implementation, the terminal uses its antenna or radio frequency resources for cell 1 or carrier 1 during the first time period T1, and uses its antenna or radio frequency resources for cell 2 or carrier 2 during the second time period T2. That is, it performs reception and / or transmission operations for cell 1 or carrier 1 during T1, and performs reception and / or transmission operations for cell 2 or carrier 2 during T2.

[0035] S120 determines the measurement indicators for different time periods based on the switching configuration.

[0036] In some embodiments, the measurement metrics for different time-division time periods may include: measurement type, measurement execution range, gap measurement strategy, searcher allocation strategy, and carrier-specific scaling factor (CSSF) for different time-division time periods.

[0037] In the above embodiments, the measurement type is used to indicate whether the terminal uses same-frequency measurement or different-frequency measurement, and whether it uses in-gap measurement or out-of-gap measurement in different time-division time periods T1 and T2, so as to reduce or avoid the impact on measurement after introducing transmission switching or reception switching between different frequency ranges.

[0038] In the above embodiments, the measurement execution range is used to indicate whether the terminal performs a measurement, and which cells, carriers or frequency bands are measured or not in different time-division time periods T1 and T2, so as to reduce or avoid the impact on the measurement after introducing transmit or receive switching between different frequency ranges.

[0039] In the above embodiments, the gap measurement strategy is used to instruct the terminal to execute or not execute the gap-related measurement strategy in different time-division time periods T1 and T2, so as to avoid interruptions caused by gap opportunities and scheduling restrictions on uplink and downlink channels or uplink and downlink signal transmissions on different service frequency bands, thereby reducing or avoiding the impact on measurement after introducing transmit or receive switching between different frequency ranges.

[0040] In the above embodiments, the searcher allocation strategy and CSSF are used to instruct the terminal on the allocation strategy of the searcher and the method of calculating the CSSF under the allocation strategy when performing measurements in different time-division time periods T1 and T2. By allocating the searcher and calculating the CSSF, the time required to perform each measurement can be estimated, and multiple measurements can be coordinated within the terminal's limited measurement resource capabilities, thereby reducing or avoiding the impact on the measurement after introducing transmit or receive switching between different frequency ranges.

[0041] S130, based on the above measurement indicators, perform the measurement.

[0042] The measurement method under multi-carrier switching provided in this embodiment obtains different measurement indicators and performs measurements based on these indicators. This reduces or avoids the impact on measurements caused by antenna radiation bandwidth limitations, which may prevent the inclusion of multiple component carriers or frequency bands, when transmission or reception switching is introduced between different frequency ranges. This improves the stability and accuracy of measurements after transmission or reception switching between different frequency ranges.

[0043] The technical solutions provided in the embodiments of this application are described below through specific examples.

[0044] Example 1

[0045] In the measurement method under multi-carrier switching provided in this embodiment, the measurement index is used to describe the measurement type in different time-division time periods.

[0046] Figure 2 shows a flowchart of the measurement method under multi-carrier switching provided in Embodiment 1 of this application. As shown in Figure 2, the measurement method under multi-carrier switching mainly includes the following steps (S210-S230).

[0047] S210, obtain the handover configuration, wherein the handover configuration is the time-division enabling configuration configured by the base station for the terminal.

[0048] For a detailed explanation, please refer to the description of step S110 in the measurement method under multi-carrier switching shown in Figure 1 above. It will not be repeated here.

[0049] S220 determines the measurement indicators for different time periods based on the switching configuration.

[0050] As one embodiment of an exemplary embodiment of this application, the measurement indicators in different time-division time periods may include: measurement types in different time-division time periods;

[0051] Determining the measurement metrics for different time periods based on the switching configuration may include the following steps:

[0052] Step 1: Determine the measurement type within the first time period T1 of the measurement range included in the second service frequency band according to the switching configuration.

[0053] Step 2: Determine the measurement type within the second time period T2 for the measurements within the frequency range included in the first service frequency band, based on the switching configuration.

[0054] Specifically, for measurements within the first time period T1, as an embodiment of an exemplary embodiment of this application, the measurement type of measurements within the frequency range of the second service frequency band within the first time period T1 is determined according to the switching configuration, including at least one of the following: (1) determining that the measurement type of measurements within the frequency range of the second service frequency band within the first time period T1 is inter-frequency measurement; (2) determining that the measurement type of measurements within the frequency range of the second service frequency band within the first time period T1 is inter-gap measurement.

[0055] In one application example, during the first time period T1, regardless of whether the center frequency of the downlink measurement signal is the same as the center frequency of the reference downlink measurement signal on cell 2, carrier 2, or frequency band 2, the measurement type is determined to be inter-frequency measurement.

[0056] Specifically, the downlink measurement signal is a downlink signal such as a Synchronization Signal and PBCH block (SSB), Channel State Information RS (CSI-RS), or Tracking Reference Signal (TRS), configured by the Measurement Object (MO) or by the serving cell configuration signaling of Cell 2 or Carrier 2. The reference downlink measurement signal is a downlink signal such as an SSB, CSI-RS, or TRS, configured by the serving cell configuration signaling of Cell 2 or Carrier 2.

[0057] In another application example, during the first time period T1, regardless of whether the subcarrier spacing (SCS) of the downlink measurement signal is the same as the SCS of the reference downlink measurement signal on cell 2 or carrier 2, the measurement type is determined to be inter-frequency measurement.

[0058] In another application example, during the first time period T1, regardless of whether the frequency range of the downlink measurement signal is completely enveloped by the active bandwidth part (BWP) on cell 2 or carrier 2, the measurement type is determined to be an in-gap measurement. Specifically, the active BWP on cell 2 or carrier 2 is deactivated by default during the first time period T1.

[0059] After receiving the RRC signaling from the base station, the terminal performs reception and / or transmission operations on cell 1, carrier 1, or frequency band 1 within time T1, and on cell 2, carrier 2, or frequency band 2 within time T2. The terminal determines that the measurement type performed on cell 2, carrier 2, or frequency band 2 within time T1 is inter-frequency measurement or inter-gap measurement, and uses the corresponding cell identification and measurement period indicators. This reduces or avoids the impact on measurements caused by antenna radiation bandwidth limitations, which may prevent the inclusion of multiple member carriers or frequency bands, when introducing transmission or reception switching between different frequency ranges. This improves the stability and accuracy of measurements after transmission or reception switching between different frequency ranges.

[0060] Specifically, for measurements within the second time period T2, as an embodiment of an exemplary embodiment of this application, the measurement type within the frequency range included in the first service frequency band during the second time period T2 is determined according to the switching configuration, including at least one of the following:

[0061] (1) Determine that the measurement type of the measurement within the frequency range of the first service frequency band during the second time period T2 is inter-frequency measurement.

[0062] (2) Determine that the measurement type of the first service frequency band within the frequency range during the second time period T2 is the inter-gap measurement.

[0063] In one application example, during the second time period T2, regardless of whether the center frequency of the downlink measurement signal is the same as the center frequency of the reference downlink measurement signal on cell 1, carrier 1, or frequency band 1, the measurement type is determined to be inter-frequency measurement.

[0064] Specifically, the downlink measurement signal is a downlink signal such as SSB, CSI-RS, or TRS, configured by the MO or by the serving cell configuration signaling of cell 1 or carrier 1. The reference downlink measurement signal is a downlink signal such as SSB, CSI-RS, or TRS, configured by the serving cell configuration signaling of cell 1 or carrier 1.

[0065] In another application example, during the second time period T2, regardless of whether the SCS of the downlink measurement signal is the same as the SCS of the reference downlink measurement signal on cell 1 or carrier 1, the measurement type is determined to be inter-frequency measurement.

[0066] In another application example, during the second time period T2, regardless of whether the frequency range of the downlink measurement signal is completely enveloped by the active BWP (active bandwidth portion) on cell 1 or carrier 1, the measurement type is determined to be an in-gap measurement. Specifically, the active BWP on cell 1 or carrier 1 is deactivated by default during the second time period T2.

[0067] After receiving the RRC signaling from the base station, the terminal performs receive and / or transmit operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal determines that the measurement type performed on cell 1, carrier 1, or frequency band 1 within T2 is inter-frequency measurement or inter-gap measurement. It uses the corresponding cell identification and measurement period indicators to perform the measurement, thereby reducing or avoiding the impact on measurements caused by antenna radiation bandwidth limitations that may prevent the inclusion of multiple member carriers or frequency bands, and thus improving the stability and accuracy of measurements after transmit or receive switching between different frequency ranges.

[0068] S230, based on the above measurement indicators, perform the measurement.

[0069] The measurement method under multi-carrier switching provided in this embodiment determines the measurement type in different time-division time periods T1 and T2, and performs the measurement based on this measurement type. This reduces or avoids the impact on the measurement caused by the limited antenna radiation bandwidth in related technologies, which may not be able to include multiple component carriers or frequency bands, after introducing transmission or reception switching between different frequency ranges. This improves the stability and accuracy of the measurement after transmission or reception switching between different frequency ranges.

[0070] Example 2

[0071] In the measurement method under multi-carrier switching provided in this embodiment, the measurement index is used to describe the measurement execution range in different time-division time periods.

[0072] Figure 3 shows a flowchart of a measurement method under multi-carrier handover provided in an exemplary embodiment of this application. As shown in Figure 3, the measurement method under multi-carrier handover mainly includes the following steps (S310-S330):

[0073] S310, obtain handover configuration, where the handover configuration is the time-division enabling configuration configured by the base station for the terminal.

[0074] For a detailed explanation, please refer to the description of step S110 in the measurement method under multi-carrier switching shown in Figure 1 above. It will not be repeated here.

[0075] S320 determines the measurement indicators for different time periods based on the switching configuration.

[0076] As one embodiment of an exemplary embodiment of this application, the measurement index within different time-division time periods may include: the measurement execution range within different time-division time periods. Determining the measurement index within different time-division time periods based on the switching configuration may include the following steps:

[0077] Step 1: Determine the measurement execution range within the first time period T1 based on the switching configuration.

[0078] Step 2: Determine the measurement execution range within the second time period T2 based on the switching configuration.

[0079] Specifically, for measurements within the first time period T1, as an embodiment of an exemplary embodiment of this application, the measurement execution range within the first time period T1 is determined according to the switching configuration, including at least one of the following:

[0080] (1) Determine whether to perform measurements on cells, carriers or frequency points within the frequency range of the first service frequency band during the first time period T1.

[0081] (2) Determine whether to perform measurements on cells, carriers or frequency points outside the frequency range of the first service frequency band and outside the frequency range of the second service frequency band within the first time period T1.

[0082] (3) Determine the measurement objects to be measured in other systems or other access networks during the first time period T1, wherein other systems or other access networks are systems or access networks other than the New Radio (NR) system.

[0083] (4) Determine whether to perform measurements on cells, carriers or frequency points within the frequency range of the first service frequency band and / or outside the frequency range of the second service frequency band during the first time period T1.

[0084] (5) Determine whether to perform measurements on cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1.

[0085] (6) Determine whether to perform measurements on cells, carriers or frequency points outside the frequency range of the first service frequency band within the first time period T1, based on the first criterion.

[0086] In (6), as an embodiment of an exemplary embodiment of this application, the first criterion includes at least one of the following:

[0087] 1) Compare the first time period T1 with the first time threshold. If the first time period T1 is greater than or equal to the first time threshold, then perform measurements on cells, carriers or frequency points outside the frequency range of the first service frequency band within the first time period T1. If the first time period T1 is less than or equal to the first time threshold, then do not perform measurements on cells, carriers or frequency points outside the frequency range of the first service frequency band within the first time period T1.

[0088] 2) Compare the first time period T1 with the first time threshold. If the first time period T1 is greater than or equal to the first time threshold, then perform measurements on the cells, carriers or frequency points within the frequency range of the second service frequency band within the first time period T1. If the first time period T1 is less than or equal to the first time threshold, then do not perform measurements on the cells, carriers or frequency points within the frequency range of the second service frequency band within the first time period T1.

[0089] 3) Compare the second time period T2 with the second time threshold. If the second time period T2 is greater than or equal to the second time threshold, no measurement will be performed on cells, carriers or frequencies outside the frequency range of the first service frequency band during the first time period T1. If the second time period T2 is less than or equal to the second time threshold, measurement will be performed on cells, carriers or frequencies outside the frequency range of the first service frequency band during the first time period T1.

[0090] 4) Compare the second time period T2 with the second time threshold. If the second time period T2 is greater than or equal to the second time threshold, no measurement is performed on the cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1. If the second time period T2 is less than or equal to the second time threshold, measurement is performed on the cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1.

[0091] 5) Determine the cell type of the second service frequency band. If the cell type of the second service frequency band is a primary cell (PCell), a primary-secondary cell (PSCell), or a high-priority secondary cell, then perform measurements on the cells, carriers, or frequencies within the frequency range included in the second service frequency band during the first time period T1. If the cell type of the second service frequency band is a secondary cell (SCell) or a non-high-priority secondary cell, then do not perform measurements on the cells, carriers, or frequencies within the frequency range included in the second service frequency band during the first time period T1.

[0092] 6) During the first time period T1, perform measurements on cells, carriers, or frequency points on other frequencies that are not included in the first service frequency band or the second service frequency band.

[0093] 7) During the first time period T1, perform measurements on the measurement objects of other systems or other access networks, wherein other systems or other access networks are systems or access networks other than the NR system.

[0094] In one application example, the measurement execution range within the first time period T1 is determined based on the handover configuration. This includes: the terminal will not perform measurements on cells or frequencies outside the frequency range corresponding to cell 1 or frequency band 1 within T1; that is, it can only perform measurements on cells or frequencies within the frequency range corresponding to cell 1 or frequency band 1. The terminal will also perform measurements on frequencies outside the frequency range corresponding to cell 1 or frequency band 1, and also on frequencies outside the frequency range corresponding to cell 2 or frequency band 2 within T1. Therefore, inter-frequency measurements are not affected by the handover configuration. The terminal will perform measurements on measurement objects of other systems or other access networks within T1. In other words, intra-frequency measurements are not affected by the handover configuration.

[0095] Within T1, the terminal will not perform measurements on cells or frequencies within the frequency range corresponding to cell 2 or frequency band 2, but will only perform measurements on cells or frequencies within the frequency range corresponding to cell 1 or frequency band 1 and / or outside the frequency range corresponding to cell 2 or frequency band 2; the terminal determines whether to perform measurements on cells or frequencies outside the frequency range corresponding to cell 1 or frequency band 1 within T1 according to the first criterion.

[0096] In actual measurements, there are three main categories: the first category is the measurement of cell 1, carrier 1, and frequency band 1; the second category is the measurement of cell 2, carrier 2, and frequency band 2; and the third category is the measurement of non-cell 1 and non-cell 2 (neither cell 1, carrier 1, and frequency band 1 nor cell 2, carrier 2, and frequency band 2). In this embodiment, the range of the above measurements within the first time period T1 is determined according to the handover configuration to ensure that the first type of measurement is performed as much as possible within the first time period T1, and the second type of measurement is performed as much as possible within the second time period T2, so as to avoid the impact of transmission or reception handover between different frequency ranges on the measurements.

[0097] After receiving the RRC signaling from the base station, the terminal performs reception and / or transmission operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal determines the measurement range for different service frequency bands within T1 and performs measurements using the corresponding cell identification and measurement period. This reduces or avoids the impact on measurements caused by antenna radiation bandwidth limitations, which may prevent the inclusion of multiple component carriers or frequency bands, when introducing transmission or reception switching between different frequency ranges. This improves the stability and accuracy of measurements after transmission or reception switching between different frequency ranges.

[0098] Specifically, for the measurement in the second time period T2, as an exemplary embodiment of this application, the measurement execution range within the second time period T2 is determined according to the switching configuration, including at least one of the following:

[0099] (1) Determine whether to perform measurements on cells, carriers or frequency points within the frequency range of the second service frequency band during the second time period T2.

[0100] (2) Determine whether to perform measurements on cells, carriers or frequency points outside the frequency range of the second service band and outside the frequency range of the first service band during the second time period T2.

[0101] (3) Determine the measurement objects to be measured in other systems or other access networks during the second time period T2, wherein other systems or other access networks are systems or access networks other than the new wireless standard NR system.

[0102] (4) Determine whether to perform measurements on cells, carriers or frequency points within the frequency range of the second service band and / or outside the frequency range of the first service band during the second time period T2.

[0103] (5) Determine whether to perform measurements on cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2.

[0104] (6) Determine whether to perform measurements on cells, carriers or frequency points outside the frequency range of the second service band during the second time period T2, based on the second criterion.

[0105] In (6), as an embodiment of an exemplary embodiment of this application, the second criterion includes at least one of the following:

[0106] 1) Compare the second time period T2 with the third time threshold. If the second time period T2 is greater than or equal to the third time threshold, then perform measurements on cells, carriers or frequency points outside the frequency range included in the second service frequency band within the second time period T2. If the second time period T2 is less than or equal to the third time threshold, then do not perform measurements on cells, carriers or frequency points outside the frequency range included in the second service frequency band within the second time period T2.

[0107] 2) Compare the second time period T2 with the third time threshold. If the second time period T2 is greater than or equal to the third time threshold, then perform measurements on cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2. If the second time period T2 is less than or equal to the second time threshold, then do not perform measurements on cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2.

[0108] 3) Compare the first time period T1 with the fourth time threshold. If the first time period T1 is greater than or equal to the fourth time threshold, no measurement will be performed on cells, carriers or frequencies outside the frequency range of the second service frequency band during the second time period T2. If the first time period T1 is less than or equal to the fourth time threshold, measurement will be performed on cells, carriers or frequencies outside the frequency range of the second service frequency band during the second time period T2.

[0109] 4) Compare the first time period T1 with the fourth time threshold. If the first time period T1 is greater than or equal to the fourth time threshold, no measurement will be performed on the cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2. If the first time period T1 is less than or equal to the fourth time threshold, measurement will be performed on the cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2.

[0110] 5) Determine the cell type of the first service frequency band. If the cell type of the first service frequency band is a primary cell (PCell), a primary-secondary cell (PSCell), or a high-priority secondary cell, then perform measurements on the cells, carriers, or frequencies within the frequency range of the first service frequency band during the second time period T2. If the cell type of the first service frequency band is a secondary cell (SCell) or a non-high-priority secondary cell, then do not perform measurements on the cells, carriers, or frequencies within the frequency range of the first service frequency band during the second time period T2.

[0111] 6) During the second time period T2, perform measurements on cells, carriers, or frequency points on other frequencies that are not included in the second service frequency band or the first service frequency band.

[0112] 7) During the second time period T2, measurements are performed on other systems or other access networks, where other systems or other access networks are systems or access networks other than the new wireless standard NR system.

[0113] In one application example, the terminal will not perform measurements on cells or frequencies outside the frequency range corresponding to cell 2 or frequency band 2 within T2. ​​In other words, the terminal will only perform measurements on cells or frequencies within the frequency range corresponding to cell 2 or frequency band 2.

[0114] In another application example, the terminal performs measurements on frequencies outside the frequency range corresponding to cell 2 or frequency band 2 within T2, and also on frequencies outside the frequency range corresponding to cell 1 or frequency band 1. Therefore, inter-frequency measurements are not affected by the handover configuration.

[0115] In another application example, the terminal performs measurements on other systems or other access network objects within T2. ​​That is, same-frequency measurements are not affected by configuration switching.

[0116] In another application example, the terminal will not perform measurements on cells or frequencies within the frequency range corresponding to cell 1 or frequency band 1 within T2, but will only perform measurements on cells or frequencies within the frequency range corresponding to cell 2 or frequency band 2 and / or outside the frequency range corresponding to cell 1 or frequency band 1.

[0117] In another application example, the terminal determines, based on a first criterion, whether to perform measurements on cells or frequencies outside the frequency range corresponding to cell 2 or frequency band 2 within T2.

[0118] In actual measurements, there are three main categories: the first category is the measurement of cell 1, carrier 1, and frequency band 1; the second category is the measurement of cell 2, carrier 2, and frequency band 2; and the third category is the measurement of non-cell 1 and non-cell 2 (neither cell 1, carrier 1, and frequency band 1 nor cell 2, carrier 2, and frequency band 2). In this embodiment, the range of the above measurements to be performed in the second time period T2 is determined according to the handover configuration to ensure that the first type of measurement is performed as much as possible in the first time period T1 and the second type of measurement is performed as much as possible in the second time period T2, so as to avoid the impact of transmission or reception handover between different frequency ranges on the measurements.

[0119] After receiving the RRC signaling from the base station, the terminal performs reception and / or transmission operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal determines the measurement range for different service frequency bands within T2 and performs measurements using the corresponding cell identification and measurement period. This reduces or avoids the impact on measurements caused by antenna bandwidth limitations, which may prevent the inclusion of multiple component carriers or frequency bands, when introducing transmission or reception switching between different frequency ranges. This improves the stability and accuracy of measurements after transmission or reception switching between different frequency ranges.

[0120] S330, based on the above measurement indicators, performs the measurement.

[0121] The measurement method under multi-carrier switching provided in this embodiment determines the measurement execution range strategy within different time-division time periods T1 and T2, and performs the measurement based on this measurement execution range strategy. This reduces or avoids the impact on the measurement caused by the limited antenna radiation bandwidth in related technologies, which may prevent the inclusion of multiple component carriers or frequency bands, after introducing transmit or receive switching between different frequency ranges. This improves the stability and accuracy of the measurement after transmit or receive switching between different frequency ranges.

[0122] Example 3

[0123] In the measurement method under multi-carrier switching provided in this embodiment, the measurement index is described as a gap measurement strategy in different time-division time periods.

[0124] Figure 4 shows a flowchart of a measurement method under multi-carrier handover provided in an exemplary embodiment of this application. As shown in Figure 4, the measurement method under multi-carrier handover mainly includes the following steps (S410-S430):

[0125] S410, obtain handover configuration, where the handover configuration is the time-division enabling configuration configured by the base station for the terminal.

[0126] For a detailed explanation, please refer to the description of step S110 in the measurement method under multi-carrier switching shown in Figure 1 above. It will not be repeated here.

[0127] S420 determines the measurement indicators for different time periods based on the switching configuration.

[0128] As one embodiment of an exemplary embodiment of this application, the measurement indicators in different time-division time periods include: a gap measurement strategy in different time-division time periods. Determining the measurement indicators in different time-division time periods according to the switching configuration may include the following steps:

[0129] Step 1: Determine the gap measurement strategy within the first time period T1 based on the switching configuration.

[0130] Step 2: Determine the gap measurement strategy within the second time period T2 based on the switching configuration.

[0131] Specifically, to avoid interruptions during gap opportunities, for measurements within the first time period T1, as an optional implementation of an exemplary embodiment of this application, a gap measurement strategy within the first time period T1 is determined based on the switching configuration, including at least one of the following:

[0132] (1) No gap measurements are performed on cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1.

[0133] (2) During the first time period T1, the gap mode configuration used for gap measurement is deactivated or deenabled.

[0134] (3) If an in-gap measurement is performed on a cell, carrier or frequency point within the frequency range of the second service band during the first time period T1, then all gap opportunities during the first time period T1 that overlap with the time domain of the reference signal RS used for in-gap measurement are used for in-gap measurement.

[0135] (4) Perform gap-out measurements on cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1.

[0136] In one application example, by configuring the measurement object MO, if the terminal does not perform inter-gap measurements on cell 2 or carrier 2 or within the frequency range of frequency band 2 during T1, then the measurement will not cause an interruption.

[0137] In another application example, the base station will configure multiple gap patterns for measurement for the terminal. If at least one of the multiple gap patterns for measurement is deactivated or disabled within the time period T1, no interruption will occur on the gap opportunity corresponding to the deactivated or disabled gap pattern, thus avoiding the impact of switching configurations on the measurement.

[0138] In another application example, if the terminal performs an in-gap measurement on cell 2 or carrier 2 or within the frequency range of frequency band 2 within time T1, then all gap opportunities within T1 that overlap with the RS time domain used for the in-gap measurement are used for the in-gap measurement. A set of gap patterns configured by the base station for the terminal includes multiple gap opportunities. Assuming there are 5 gap opportunities within time T1, if all 5 gap opportunities are allocated to cell 2 or carrier 2 or within the frequency range of frequency band 2 for in-gap measurements, the measurements can be completed centrally within time T1 without occupying time T2, thus avoiding the impact of handover. Simultaneously, the third type of measurement mentioned in Example 2 above will also not occupy gap opportunities within time T1, further avoiding the impact of handover.

[0139] In another application example, the terminal performs measurements outside the gap only for cell 2 or carrier 2 or within the frequency range of frequency band 2 during time period T1, thus not affecting measurements within the gap.

[0140] After receiving RRC signaling from the base station, the terminal performs receive and / or transmit operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal determines the gap measurement strategy for cell 2, carrier 2, or frequency band 2 within T1, and performs measurements using the corresponding cell identification and measurement period. This reduces or avoids the impact on measurements caused by antenna bandwidth limitations, which may prevent the inclusion of multiple member carriers or frequency bands, when introducing transmit or receive switching between different frequency ranges. This improves the stability and accuracy of measurements after transmit or receive switching between different frequency ranges.

[0141] Specifically, to avoid interruptions during gap opportunities, for measurements within the second time period T2, as an exemplary embodiment of this application, a gap measurement strategy within the second time period T2 is determined based on the switching configuration, including at least one of the following:

[0142] (1) No gap measurements are performed on cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2.

[0143] (2) During the second time period T2, the gap mode configuration used for gap measurement is deactivated or deenabled.

[0144] (3) If an in-gap measurement is performed on a cell, carrier or frequency point within the frequency range of the first service band during the second time period T2, then all gap opportunities during the second time period T2 that overlap with the time domain of the reference signal RS used for in-gap measurement are used for in-gap measurement.

[0145] (4) Perform gap-out measurements on cells, carriers or frequency points within the frequency range of the first service frequency band during the second time period T2.

[0146] In one application example, by configuring MO, if the terminal does not perform inter-gap measurements on cell 1 or carrier 1 or within the frequency range of band 1 during T2, then the measurement will not cause an interruption.

[0147] In another application example, the base station will configure multiple gap patterns for measurement for the terminal. If at least one of the multiple gap patterns for measurement is deactivated or disabled within T2, no interruption will occur on the gap opportunity corresponding to the deactivated or disabled gap pattern, thus avoiding the impact of switching configurations on the measurement.

[0148] In another application example, if the terminal performs an in-gap measurement on cell 1, carrier 1, or within the frequency range of frequency band 1 within time period T2, then all gap opportunities within T2 that overlap with the RS time domain used for the in-gap measurement are used for the in-gap measurement. A set of gap patterns configured by the base station for the terminal includes multiple gap opportunities. Assuming there are 5 gap opportunities within time period T2, if all 5 gap opportunities are allocated to cell 1, carrier 1, or within the frequency range of frequency band 1 for in-gap measurements, the measurements can be completed centrally within time period T2 without occupying time period T1. This avoids the impact of handover. Simultaneously, the third type of measurement mentioned in Example 2 above will also not occupy gap opportunities within time period T2, further avoiding the impact of handover.

[0149] In another application example, the terminal performs measurements outside the gap only for cell 1 or carrier 1 or within the frequency range of frequency band 1 during time period T2, thus not affecting measurements within the gap.

[0150] After receiving the RRC signaling from the base station, the terminal performs receive and / or transmit operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal determines the gap measurement strategy to be performed on cell 1, carrier 1, or frequency band 1 within T2, and performs measurements using the corresponding cell identification and measurement period. This reduces or avoids the impact on measurements caused by antenna radiation bandwidth limitations, which may prevent the inclusion of multiple member carriers or frequency bands, when introducing transmit or receive switching between different frequency ranges. This improves the stability and accuracy of measurements after transmit or receive switching between different frequency ranges.

[0151] Specifically, to avoid scheduling constraints, for measurements within the first time period T1, as an exemplary embodiment of this application, a gap measurement strategy within the first time period T1 is determined based on the switching configuration, including at least one of the following:

[0152] (1) No gap-out measurements are performed on cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1, and no scheduling restrictions on downlink channels or downlink signal transmissions of the first service frequency band are generated on the RS opportunity configured for gap-out measurements.

[0153] (2) No gap-out measurements are performed on cells, carriers or frequency points within the frequency range of the second service frequency band during the first time period T1, and no scheduling restrictions on uplink channels or uplink signal transmission of the first service frequency band are generated on the RS opportunity configured for gap-out measurements.

[0154] In one application example, if the terminal does not perform out-of-gap measurements on cell 2 or carrier 2 or within the frequency range of frequency band 2 during T1, there will be no interruption of gap opportunities or scheduling restrictions due to the measurements. Therefore, no scheduling restrictions will be generated on the uplink / downlink channels or downlink signal transmission of cell 1 or carrier 1 when configuring RS opportunities for the measurements. The downlink channel may be a Physical Downlink Control Channel (PDCCH), a Physical Downlink Shared Channel (PDSCH), message 2 (Msg 2) in the random access procedure, or message 4 (Msg 4) in the random access procedure, etc. The downlink signal may be an SSB, CSI-RS, TRS, or a Demodulation Reference Signal (DMRS), etc.

[0155] In another application example, if the terminal does not perform out-of-gap measurements (measurements performed without measurement gaps) on cell 2 or carrier 2 or within the frequency range of frequency band 2 during T1, then there will be neither interruption of gap opportunities nor scheduling restrictions due to the measurements. Therefore, no scheduling restrictions will be generated on uplink channel or uplink signal transmission on cell 1 or carrier 1 when configuring RS opportunities for the measurements. The uplink channel can be a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Random Access Channel (RACH), or Message 3 (Msg 3) in the random access procedure, etc. The uplink signal can be a Sounding Reference Signal (SRS) or DMRS, etc.

[0156] After receiving the RRC signaling from the base station, the terminal can perform receive and / or transmit operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal does not perform out-of-gap measurements on cell 2, carrier 2, or frequency band 2 within T1. This avoids gap opportunity interruptions and scheduling restrictions, and prevents scheduling limitations on uplink / downlink channels or uplink / downlink signal transmission on cell 1, carrier 1, or frequency band 1. This reduces or avoids the impact on measurements after introducing transmit or receive handover between different frequency ranges.

[0157] Specifically, to avoid scheduling constraints, for measurements within the second time period T2, as an exemplary embodiment of this application, a gap measurement strategy within the second time period T2 is determined based on the switching configuration, including at least one of the following:

[0158] (1) During the second time period T2, no gap-out measurements are performed on cells, carriers or frequency points within the frequency range of the first service frequency band, and no scheduling restrictions on downlink channels or downlink signal transmissions of the second service frequency band are generated when configuring the reference signal RS for gap-out measurements.

[0159] (2) During the second time period T2, no gap-out measurements are performed on cells, carriers or frequency points within the frequency range of the first service frequency band, and no scheduling restrictions on uplink channels or uplink signal transmission of the second service frequency band are generated when configuring the reference signal RS for gap-out measurements.

[0160] In one application example, if the terminal does not perform out-of-gap measurements on cell 1, carrier 1, or within the frequency range of band 1 during T2, there will be no interruption of gap opportunities or scheduling restrictions due to the measurements. Therefore, no scheduling restrictions will be incurred on downlink channel or downlink signal transmission on cell 2, carrier 2, or band 2 when configuring RS opportunities for the measurements. The downlink channel may be PDCCH, PDSCH, Msg 2, or Msg 4, etc. The downlink signal may be SSB, CSI-RS, TRS, or DMRS, etc.

[0161] In another application example, if the terminal does not perform out-of-gap measurements (measurements performed without measurement gaps) on cell 1, carrier 1, or within the frequency range of frequency band 1 during T2, then there will be neither gap opportunity interruption nor scheduling restrictions due to the measurement. Therefore, no scheduling restrictions will arise on uplink channel or uplink signal transmission on cell 2, carrier 2, or frequency band 2 when configuring RS opportunities for the measurement. The uplink channel can be PUCCH, PUSCH, RACH, or Msg 3, etc. The uplink signal can be SRS or DMRS, etc.

[0162] After receiving the RRC signaling from the base station, the terminal can perform receive and / or transmit operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​The terminal does not perform out-of-gap measurements on cell 1, carrier 1, or frequency band 1 within T2, thus avoiding gap opportunity interruptions and scheduling restrictions, and preventing scheduling restrictions on uplink / downlink channels or uplink / downlink signal transmission on cell 2, carrier 2, or frequency band 2. This reduces or avoids the impact on measurements after introducing transmit or receive handover between different frequency ranges.

[0163] S430, based on the above measurement indicators, performs the measurement.

[0164] The measurement method under multi-carrier switching provided in this embodiment determines the gap measurement strategy in different time-division time periods T1 and T2, and performs the measurement based on this measurement type. The measurement will not cause interruption of gap opportunities or scheduling restrictions. This avoids the impact on the measurement caused by the limited antenna radiation bandwidth, which may not be able to include multiple component carriers or frequency bands, after introducing transmit or receive switching between different frequency ranges. This provides stability and accuracy of the measurement after transmit or receive switching between frequency ranges.

[0165] Example 4

[0166] In the measurement method under multi-carrier handover provided in this embodiment, the measurement index is used to describe the searcher allocation strategy and the corresponding CSSF calculation method in different time-division time periods.

[0167] Figure 5 shows a flowchart of a measurement method under multi-carrier handover provided in an exemplary embodiment of this application. As shown in Figure 5, the measurement method under multi-carrier handover mainly includes the following steps (S510-S530):

[0168] S510, obtain handover configuration, where the handover configuration is the time-division enabling configuration configured by the base station for the terminal.

[0169] For a detailed explanation, please refer to the description of step S110 in the measurement method under multi-carrier switching shown in Figure 1 above. It will not be repeated here.

[0170] The S520 determines the measurement indicators for different time periods based on the switching configuration.

[0171] As one embodiment of an exemplary embodiment of this application, the measurement metrics in different time-division time periods include: searcher allocation strategies and corresponding CSSFs in different time-division time periods.

[0172] A searcher is a software module, algorithm, or hardware component used to perform search functions during signal and cell searches in a 5G network. It is responsible for searching for specific signals, cell identifiers, and other information in the wireless environment to enable devices to connect to and synchronize with the 5G network.

[0173] In actual implementation, the terminal can perform multiple measurements, but it only has two searchers. Due to the limitations of the terminal's capabilities, the CSSF amplification factor can be used to estimate the time required to execute each measurement under different searcher allocation strategies. This allows multiple measurements to be completed in a shorter time within the terminal's limited measurement resource capabilities.

[0174] As an exemplary embodiment of this application, determining the measurement index in different time-division time periods according to the switching configuration may include the following steps:

[0175] Step 1: Determine the searcher allocation strategy and the corresponding carrier-specific scaling factor (CSSF) within the first time period T1 based on the handover configuration.

[0176] Step 2: Determine the searcher allocation strategy and the corresponding carrier-specific scaling factor (CSSF) for the second time period T2 based on the handover configuration.

[0177] Specifically, for measurements within the first time period T1, the searcher allocation strategy within the first time period T1 is determined based on the switching configuration, including at least one of the following:

[0178] (1) Determine that all searchers will be used for the measurement of cells, carriers or frequency points within the frequency range of the first service frequency band during the first time period T1.

[0179] (2) Determine the cell type of the first service frequency band. If the cell type of the first service frequency band is a primary cell (PCell) or a primary-secondary cell (PSCell), then during the first time period T1, use one searcher for all types of measurements on cells, carriers or frequency points within the frequency range of the first service frequency band, and use another searcher for inter-frequency measurements and / or inter-system measurements other than those on cells, carriers or frequency points within the frequency range of the first service frequency band.

[0180] (3) Determine the cell type of the first service frequency band. If the cell type of the first service frequency band is a secondary cell (SCell), then during the first time period T1, use one searcher for all types of measurements on cells, carriers or frequency points within the frequency range of the first service frequency band, and use another searcher for inter-frequency measurements and / or inter-system measurements other than cells, carriers or frequency points within the frequency range of the first service frequency band.

[0181] (4) Determine the cell type of the first service frequency band. If the cell type of the first service frequency band is a secondary cell SCell, then during the first time period T1, use all searchers for all types of measurements on cells, carriers or frequency points within the frequency range of the first service frequency band, as well as inter-frequency measurements and / or inter-system measurements other than cells, carriers or frequency points within the frequency range of the first service frequency band.

[0182] In some implementations, for measurements within a first time period T1, a carrier-specific scaling factor (CSSF) for the first time period T1 is determined based on the handover configuration, including one of the following methods:

[0183] (1) Corresponding to the searcher allocation strategy in the first time period T1, when calculating CSSF in T1, the influence of measurements within the frequency range of cell 2, carrier 2, or frequency band 2 on CSSF calculation is not considered.

[0184] (2) Corresponding to method (2) in the searcher allocation strategy within the first time period T1, if the cell type of the first service frequency band belongs to the primary cell or the primary-secondary cell, the carrier-specific scaling factor CSSF within the first time period T1 is calculated in the following way:

[0185] The CSSF of the first service frequency band = 1 + N PCC_CSIRS +NPCC_CCA_RSSI / CO For a heterogeneous frequency MO without measurement gap, the CSSF = Y + Z. For a heterogeneous E-UTRA system MO without measurement gap, the CSSF = Y + Z.

[0186] Specifically, if the primary cell PCC is configured with L3 measurements based on SSB and CSI-RS, or only configured with L3 measurements based on CSI-RS, then N PCC_CSIRS =1; otherwise, N PCC_CSIRS =0; When RSSI-based Measurement Timing Configuration (RMTC) and SSB-based Measurement Timing Configuration (SMTC) overlap, if the primary and secondary cell PSCCs configure Received Signal Strength Indication (RSSI) / Channel Occupancy (CO) measurement without configuring measurement gaps, then N PCC_CCA_RSSI / CO =1; Y represents the number of configured heterogeneous frequency MOs that are being measured outside the measurement gap and do not have a measurement gap configured; otherwise, Y is 0; Z represents the number of configured E-UTRA heterogeneous frequency MOs that are being measured outside the measurement gap and do not have a measurement gap configured; otherwise, Z is 0.

[0187] (3) Corresponding to the searcher allocation strategy in the first time period T1, if the cell type of the first service frequency band is a secondary cell, and one searcher is used for all types of measurements on cells, carriers or frequency points within the frequency range of the first service frequency band, and another searcher is used for inter-frequency measurements and / or inter-system measurements other than those on cells, carriers or frequency points within the frequency range of the first service frequency band, the carrier-specific scaling factor CSSF is calculated in the following way within the first time period T1: CSSF of the first service frequency band = N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO For inter-frequency MOs without measurement gaps, the CSSF is Y + Z; for inter-system MOs without measurement gaps, the CSSF is Y + Z; or, for the first service frequency band, the CSSF is 1 + N. SCC_CSIRS +N SCC_CCA_RSSI / CO For a non-interval MO without measurement gaps, the CSSF = Y + Z. For a non-interval E-UTRA non-interval MO without measurement gaps, the CSSF = Y + Z.

[0188] Where, NSCC_SSB N represents the number of configured secondary cells that perform L3 measurements based solely on SSB and without measurement gaps. SCC_CSIRS The number of configured secondary cells that have L3 measurements configured using both SSB and CSI-RS, or only L3 measurements configured using CSI-RS; N SCC_CCA_RSSI / CO When RMTC and SMTC overlap, the number of MOs configured for secondary cells for RSSI / CO measurements without measurement gaps; if the secondary cell SCC is configured with L3 measurements based on SSB and CSI-RS, or only configured with L3 measurements based on CSI-RS, then N SCC_CSIRS =1; otherwise, N SCC_CSIRS =0; When RMTC and SMTC overlap, if the secondary cell SCC is configured with RSSI / CO measurement without configuring measurement gap, then N SCC_CCA_RSSI / CO =1.

[0189] (4) Corresponding to the searcher allocation strategy in the first time period T1, if the cell type of the first service frequency band is a secondary cell, when all searchers are used for all types of measurements on cells, carriers or frequency points within the frequency range of the first service frequency band, as well as inter-frequency measurements and / or inter-system measurements other than those on cells, carriers or frequency points within the frequency range of the first service frequency band, the carrier-specific scaling factor CSSF is calculated in the following way within the first time period T1: CSSF of the first service frequency band = 0.5 × (N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for a heterodyne MO without measurement gaps, the CSSF = 0.5 × (N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for the E-UTRA heterogeneous system MO without measurement gap, CSSF = 0.5×(N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z); or, the CSSF of the first service band = 0.5×(1+N) SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for a heterodyne MO without measurement gaps, the CSSF is 0.5×(1+N). SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for the E-UTRA heterogeneous system MO without measurement gap, CSSF = 0.5×(1+N) SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z).

[0190] In this embodiment, the terminal can perform multiple measurements, but the terminal only has two searchers. Due to the limitations of the terminal's capabilities, the CSSF of the corresponding allocation strategy is calculated by allocating the searchers. Through the CSSF amplification factor, the time required to execute each measurement under different searcher allocation strategies can be estimated. Thus, multiple measurements can be completed in a shorter time within the terminal's limited measurement resource capabilities.

[0191] In one application example, the terminal will not use the searcher for measurements within the frequency range of cell 2, carrier 2, or band 2 during time period T1; at this time, the impact of measurements within the frequency range of cell 2, carrier 2, or band 2 on the outside gap CSSF calculation is not considered.

[0192] In another application example, if cell 1 is a PCell or PSCell, or carrier 1 is a PCC or PSCC, when the terminal calculates the outside gap CSSF within T1, one searcher is used for all RS types of measurements on cell 1 or carrier 1, and another searcher is used for inter-frequency measurements and / or inter-system measurements other than those on cell 1 or carrier 1. Specifically, the CSSF calculation is shown in Table 1 below.

[0193] Table 1.

[0194] In Table 1, if the primary cell PCC is configured with L3 measurements based on SSB and CSI-RS, or only configured with L3 measurements based on CSI-RS, then N PCC_CSIRS =1; otherwise, N PCC_CSIRS =0; When RMTC and SMTC overlap, if the primary and secondary cell PSCCs are configured with RSSI / CO measurements without configuring measurement gaps, then N PCC_CCA_RSSI / CO =1; Y represents the number of configured heterogeneous frequency MOs that are being measured outside the measurement gap and do not have a measurement gap configured; otherwise, Y is 0; Z represents the number of configured E-UTRA heterogeneous frequency MOs that are being measured outside the measurement gap and do not have a measurement gap configured; otherwise, Z is 0.

[0195] In another application example, if cell 1 is a SCell or carrier 1 is an SCC, when the terminal calculates the outside gap CSSF within T1, one searcher is used for all RS types of measurements on cell 1 or carrier 1, and another searcher is used for in-channel measurements and / or inter-system measurements other than those on cell 1 or carrier 1. Specifically, the CSSF calculation is shown in Table 2 below.

[0196] Table 2.

[0197] In Table 2, (1) N SCC_SSB The number of configured secondary cells that are only configured for L3 measurements based on SSB and perform measurements without measurement gaps; (2) N SCC_CSIRS The number of configured secondary cells that have L3 measurements configured using both SSB and CSI-RS, or only L3 measurements configured using CSI-RS; N SCC_CCA_RSSI / CO When RMTC and SMTC overlap, the number of MOs configured for the secondary cell to perform RSSI / CO measurements in the absence of measurement gaps.

[0198] Alternatively, CSSF is calculated as shown in Table 3 below.

[0199] Table 3.

[0200] In Table 3, (1) if the secondary cell SCC is configured with L3 measurements based on SSB and CSI-RS, or only configured with L3 measurements based on CSI-RS, then N SCC_CSIRS =1; otherwise, N SCC_CSIRS =0; (2) When RMTC and SMTC overlap, if the secondary cell SCC is configured with RSSI / CO measurement without configuring measurement gap, then N SCC_CCA_RSSI / CO =1. (3) Y refers to the number of configured heterogeneous MOs that are being measured outside the measurement gap and are not configured with a measurement gap; otherwise, Y is 0; (4) Z refers to the number of configured E-UTRA heterogeneous system MOs that are being measured outside the measurement gap and are not configured with a measurement gap; otherwise, Z is 0.

[0201] In another application example, if cell 1 is a SCell or carrier 1 is an SCC, when the terminal calculates the outside gap CSSF within T1, it uses all searchers for {all RS types of measurements on cell 1 or carrier 1 + inter-frequency measurements and / or inter-system measurements other than those on cell 1 or carrier 1}. Specifically, the CSSF calculation is shown in Table 4 below.

[0202] Table 4.

[0203] In Table 4, (1) N SCC_SSB The number of configured secondary cell SCells that are configured only for L3 measurements based on SSB and are performed without measurement gaps; (2) N SCC_CSIRS The number of configured secondary cell SCells that have configured L3 measurements based on SSB and CSI-RS, or only configured L3 measurements based on CSI-RS; (3) N SCC_CCA_RSSI / CO(3) When RMTC and SMTC overlap, the number of MOs configured for RSSI / CO measurement for the secondary cell SCell without measurement gaps; (4) Y refers to the number of configured inter-frequency MOs that are being measured outside the measurement gap and have not been configured with measurement gaps; otherwise, Y is 0; (5) Z refers to the number of configured E-UTRA inter-system MOs that are being measured outside the measurement gap and have not been configured with measurement gaps; otherwise, Z is 0.

[0204] Alternatively, CSSF is calculated as shown in Table 5 below.

[0205] Table 5.

[0206] In Table 5, (1) if the secondary cell SCC is configured with L3 measurement based on SSB and CSI-RS, or only configured with L3 measurement based on CSI-RS, then N SCC_CSIRS =1; otherwise, N SCC_CSIRS =0. (2) When RMTC and SMTC overlap, if the secondary cell SCC is configured with RSSI / CO measurement without measurement gap, then N SCC_CCA_RSSI / CO =1. (3) Y represents the number of heterogeneous MOs configured without measurement gaps and measuring outside the measurement gaps; otherwise, Y is 0. (4) Z represents the number of E-UTRA heterogeneous system MOs configured without measurement gaps and measuring outside the measurement gaps; otherwise, Z is 0.

[0207] After receiving the RRC signaling from the base station, the terminal can perform receive and / or transmit operations on cell 1, carrier 1, or frequency band 1 within T1, and on cell 2, carrier 2, or frequency band 2 within T2. ​​Within T1, the terminal determines the searcher allocation strategy and the corresponding CSSF, and performs measurements accordingly. Using the CSSF as an amplification factor, the time required to perform each measurement under different searcher allocation strategies can be accurately calculated, thereby determining the priority of each measurement. This allows multiple measurements to be completed in a shorter time within the terminal's limited capabilities, reducing or avoiding the impact of transmit or receive handovers between different frequency ranges on the measurements.

[0208] For measurements within the second time period T2, as an exemplary embodiment of this application, the searcher allocation strategy for the second time period T2 is determined according to the switching configuration, including at least one of the following:

[0209] (1) Determine that all searchers will be used for the measurement of cells, carriers or frequency points within the frequency range of the second service band during the second time period T2.

[0210] (2) Determine the cell type of the second service frequency band. If the cell type of the second service frequency band is a primary cell PCell or a primary and secondary cell PSCell, then during the second time period T2, use one searcher for all types of measurements on cells, carriers or frequency points within the frequency range of the second service frequency band, and use another searcher for inter-frequency measurements and / or inter-system measurements other than those on cells, carriers or frequency points within the frequency range of the second service frequency band.

[0211] (3) Determine the cell type of the second service frequency band. If the cell type of the second service frequency band belongs to the secondary cell SCell, then during the second time period T2, use one searcher for all types of measurements on cells, carriers or frequency points within the frequency range of the second service frequency band, and use another searcher for inter-frequency measurements and / or inter-system measurements other than cells, carriers or frequency points within the frequency range of the second service frequency band.

[0212] (4) Determine the cell type of the second service frequency band. If the cell type of the second service frequency band is a secondary cell SCell, then during the second time period T2, use all searchers for all types of measurements on cells, carriers or frequency points within the frequency range of the second service frequency band, as well as inter-frequency measurements and / or inter-system measurements other than cells, carriers or frequency points within the frequency range of the second service frequency band.

[0213] Specifically, for measurements within the second time period T1, the carrier-specific scaling factor (CSSF) for the second time period T2 is determined based on the handover configuration, including one of the following methods:

[0214] (1) Corresponding to the searcher allocation strategy in the second time period T2, when calculating CSSF in T2, the influence of measurements within the frequency range of cell 1, carrier 1, or frequency band 1 on CSSF calculation is not considered.

[0215] (2) Corresponding to method (2) in the searcher allocation strategy during the second time period T2, if the cell type of the second service frequency band belongs to the primary cell or the primary-secondary cell, the carrier-specific scaling factor CSSF is calculated in the following way during the second time period T2:

[0216] The CSSF of the second service band is 1 + N PCC_CSIRS +N PCC_CCA_RSSI / CO For a non-interval measurement object MO without measurement gaps, CSSF = Y + Z. For a non-interval E-UTRA non-system measurement object MO without measurement gaps, CSSF = Y + Z.

[0217] Specifically, if the primary cell PCC is configured with L3 measurements based on SSB and CSI-RS, or only configured with L3 measurements based on CSI-RS, then N PCC_CSIRS=1; otherwise, N PCC_CSIRS =0; When RMTC and SMTC overlap, if the primary and secondary cell PSCCs are configured with RSSI / CO measurements without configuring the measurement gap MG, then N PCC_CCA_RSSI / CO =1; Y represents the number of configured heterogeneous MOs that are being measured outside the measurement gap MG and do not have a measurement gap MG configured; otherwise, Y is 0; Z represents the number of configured E-UTRA heterogeneous same-frequency MOs that are being measured outside the measurement gap and do not have a measurement gap configured; otherwise, Z is 0.

[0218] (3) Corresponding to the searcher allocation strategy in the second time period T2, if the cell type of the second service frequency band is a secondary cell, and one searcher is used for all types of measurements on cells, carriers or frequency points within the frequency range of the second service frequency band, and the other two searchers are used for inter-frequency measurements and / or inter-system measurements other than those on cells, carriers or frequency points within the frequency range of the first service frequency band, the carrier-specific scaling factor CSSF is calculated in the following way within the second time period T2: CSSF of the second service frequency band = N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO For a MO (Multi-Frequency Measurement Object) with no measurement gap, the CSSF is Y + Z; for a MO (Multi-Frequency Measurement Object) with no measurement gap in an E-UTRA inter-system, the CSSF is Y + Z; or, for the second service frequency band, the CSSF is 1 + N. SCC_CSIRS +N SCC_CCA_RSSI / CO For a non-interval measurement object MO without measurement gaps, CSSF = Y + Z. For a non-interval E-UTRA non-system measurement object MO without measurement gaps, CSSF = Y + Z.

[0219] Where, N SCC_SSB N represents the number of configured secondary cells that perform L3 measurements based solely on SSB and without measurement gaps. SCC_CSIRS The number of configured secondary cells that have L3 measurements configured using both SSB and CSI-RS, or only L3 measurements configured using CSI-RS; N SCC_CCA_RSSI / CO When RMTC and SMTC overlap, the number of MOs configured for secondary cells to perform RSSI / CO measurements without measurement gaps; if the secondary cell SCC is configured with L3 measurements based on SSB and CSI-RS, or only with L3 measurements based on CSI-RS, then N SCC_CSIRS =1; otherwise, N SCC_CSIRS =0; When RMTC and SMTC overlap, if the secondary cell SCC is configured with RSSI / CO measurement without configuring measurement gap, then N SCC_CCA_RSSI / CO =1.

[0220] (4) Corresponding to the searcher allocation strategy in the second time period T2, if the cell type of the second service frequency band is a secondary cell, when all searchers are used for all types of measurements on cells, carriers or frequency points within the frequency range of the second service frequency band, as well as inter-frequency measurements and / or inter-system measurements other than those on cells, carriers or frequency points within the frequency range of the second service frequency band, the carrier-specific scaling factor CSSF is calculated in the following way within the second time period T2: CSSF of the second service frequency band = 0.5 × (N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for the heterogeneous frequency measurement object MO without measurement gap, CSSF = 0.5×(N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for the E-UTRA heterogeneous system measurement object MO without measurement gap, CSSF = 0.5×(N SCC_SSB +2×N SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z); or, the CSSF of the second service band = 0.5×(1+N) SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for a heterogeneous frequency measurement object MO without measurement gaps, the CSSF = 0.5×(1+N) SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z), for the E-UTRA heterogeneous system measurement object MO without measurement gap, CSSF = 0.5×(1+N) SCC_CSIRS +N SCC_CCA_RSSI / CO +Y+Z).

[0221] The searcher allocation strategy and corresponding CSSF calculation method in the second time period T2 are similar to those in the first time period T1. They will not be detailed in a specific application example here. For related matters, please refer to the application example of the searcher allocation strategy and corresponding CSSF calculation method in the first time period T1 mentioned above.

[0222] In this embodiment, the terminal can perform multiple measurements, but the terminal only has two searchers. Due to the limitations of the terminal's capabilities, the CSSF of the corresponding allocation strategy is calculated by allocating the searchers. Through the CSSF amplification factor, the time required to execute each measurement under different searcher allocation strategies can be estimated. Thus, multiple measurements can be completed in a shorter time within the terminal's limited measurement resource capabilities.

[0223] S530 performs measurements based on the aforementioned measurement indicators.

[0224] The measurement method under multi-carrier handover provided in this embodiment determines the allocation strategy of the searcher and the corresponding CSSF calculation method in different time-division time periods T1 and T2, and performs measurements based on this. Through the CSSF amplification factor, the time for each measurement can be accurately calculated under different searcher allocation strategies, thereby determining the priority of each measurement. Multiple measurements can be completed in a shorter time within the limited capabilities of the terminal, thus avoiding the impact on measurements caused by antenna radiation bandwidth limitations that may prevent the inclusion of multiple component carriers or frequency bands after introducing transmit or receive handover between different frequency ranges in related technologies. This provides stability and accuracy of measurements after transmit or receive handover between frequency ranges.
