Description

Measurement in switching mode, configuration method for switching mode, nodes and media

[0001] This disclosure claims priority to Chinese Patent Application No. 202510384921.0, filed with the Chinese Patent Office on March 28, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, such as measurement in switching modes, configuration methods for switching modes, nodes, and media. Background Technology

[0003] In wireless communication systems, there is a trade-off between antenna gain and fractional bandwidth. Better radiation characteristics in a specific direction limit bandwidth. In some carrier aggregation (CA) or dual connectivity (DC) combinations, due to antenna size and cost considerations for communication nodes, the same antenna or RF resource may be used for signal transmission across multiple frequency bands / carriers. However, to ensure a certain antenna gain, the antenna's fractional bandwidth must not exceed a certain empirical value, thus limiting the antenna's radiation bandwidth and potentially preventing it from encompassing multiple member frequency bands / carriers. Using switching methods (such as transmit antenna switching, receive antenna switching, transmit RF resource switching, and receive RF resource switching) allows the same antenna or RF resource to be used in a time-division manner across multiple frequency bands / carriers. However, introducing these methods into wireless communication systems can impact resource measurement processes. Summary of the Invention

[0020] It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this disclosure. Embodiments of this disclosure will be described below with reference to the accompanying drawings.

[0021] To support wireless signal coverage across different frequency bands, communication nodes (such as terminal devices and access network equipment) deploy multiple antennas to cover low-frequency, mid-frequency, and high-frequency signal transmission. Different types of antennas have varying bandwidth coverage capabilities, which are typically described using fractional bandwidth to characterize the antenna's performance stability at different frequencies. Regardless of the antenna type, there is a trade-off between gain and fractional bandwidth: high-gain antennas are often designed with narrower bandwidths, resulting in smaller fractional bandwidths; while broadband antennas typically have lower gain because better radiation characteristics in a specific direction limit the bandwidth.

[0022] In some CA or DC combinations, due to limitations in antenna size and terminal equipment cost, the same antenna or RF resource may be used for signal transmission across multiple frequency bands / carriers. However, to ensure a certain antenna gain, the antenna's fractional bandwidth must not exceed a certain empirical value, resulting in a limited antenna radiation bandwidth that may not be able to cover multiple member frequency bands / carriers. Therefore, it is necessary to introduce switching methods (such as transmit antenna switching, receive antenna switching, transmit RF resource switching, and receive RF resource switching) to allow the same antenna or RF resource to be applied to multiple frequency bands / carriers in a time-division manner. However, the introduction of such transmit or receive switching between different frequency ranges may have the following impacts:

[0023] 1) It affects the activation / deactivation process of resources.

[0024] For example, during the activation / deactivation of a secondary cell (SCell), the terminal device needs to perform several measurements on the synchronization signal and the physical broadcast channel block (SSB) or tracking reference signal (TRS) transmitted on the SCell to complete automatic gain control (AGC), cell search, and fine time tracking. These SSB- or TRS-based measurements do not require gaps. However, with the introduction of a handover between the primary cell (PCell) and at least one SCell, considering that the terminal device may switch to the PCell during certain time periods, how to ensure a trade-off between the SCell activation delay and the interruptions caused by SSB- or TRS-based measurements during SCell activation is a problem that needs to be addressed.

[0025] 2) It has an impact on same-frequency or different-frequency measurements.

[0026] Whether in-frequency or out-of-frequency measurements require a gap depends on whether the reference signal (RS) configuration at the frequency to be measured is completely enveloped by the active downlink bandwidth part (active DL BWP) of the current serving cell. If the RS configuration at the frequency to be measured is completely enveloped by the active DL BWP of the current serving cell, the measurement can be performed without a gap, i.e., gapless measurement. Conversely, the measurement requires a gap, i.e., gap-within-a-gap measurement. Therefore, the assumption of the active DL BWP on the PCell or SCell is crucial in determining whether it is a gapless or gap-within-a-gap measurement. However, after introducing receive handover between the PCell and at least one SCell, how to determine the active DL BWP is also a problem that needs to be solved.

[0027] 3) Considering that traditional (legacy) technologies already support SSB-less SCell operations in co-located deployments, in scenarios where receive handover is introduced, it is also an issue that needs to be addressed whether the terminal device performs SSB-less SCell operations or SSB-based measurement operations for SCells.

[0028] The measurement method and configuration method for handover modes provided in this disclosure can be applied to various wireless communication systems, such as Long Term Evolution (LTE) systems, 4th-generation (4G) systems, 5th-generation (5G) systems, LTE and 5G hybrid architecture systems, 5G New Radio (NR) systems, and new communication systems emerging in future communication development, such as 6th-generation (6G) systems. Figure 1 is a network diagram of a wireless communication system provided in an embodiment. As shown in Figure 1, the wireless communication system includes a terminal device 110, an access network device 120, and a core network device 130.

[0029] Terminal device 110 can be a device with wireless transceiver capabilities, which can be deployed on land (such as indoors or outdoors, handheld, wearable or vehicle-mounted); on water (such as ships); or in the air (such as airplanes, balloons and satellites). Examples of terminal devices 110 include: wireless terminals, user equipment (UE), mobile phones, mobile stations, tablet computers, laptops, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), and other network-connected user devices; virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc.; IoT nodes in the Internet of Things (IoT); in-vehicle communication devices in the Internet of Vehicles (IoV); entertainment and gaming devices or systems; and GPS devices, etc. The embodiments of this disclosure do not limit the specific technologies or device forms used in the terminal devices. Furthermore, the term "terminal device" can be abbreviated as "terminal."

[0030] Access network equipment 120 is an access device through which terminal equipment 110 wirelessly accesses the wireless communication system. It can be a reader / writer, a base station, an evolved NodeB (eNB or eNodeB) in Long Term Evolution Advanced (LTE), a transmission reception point (TRP), a base station in a 5G mobile communication system, a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a Wireless Fidelity (WiFi) system. Base stations can include various macro base stations, micro base stations, femtobase stations, wireless extensions, routers, WiFi devices, or various network-side devices such as PCells and SCells, as well as location management function (LMF) devices. It can also be a module or unit that performs some of the functions of a base station; for example, it can be a central unit (CU) or a distributed unit (DU). The embodiments of this disclosure do not limit the specific technology or equipment form used in the access network equipment. Furthermore, the access network equipment can be simply referred to as a base station.

[0031] Core network equipment 130 may include access and mobility management network elements and session management network elements. For example, terminal equipment 110 can access the core network through access network equipment 120 to achieve data transmission.

[0032] In this embodiment of the disclosure, a measurement method, a configuration method for the switching mode, a node, and a medium that can operate in the switching mode of the above-mentioned wireless communication system are provided. This method enables the measurement of resources and improves system performance when the same antenna or radio frequency resource is applied to multiple frequency bands / carriers in a time-division manner through switching.

[0033] The following describes the measurement method, configuration method, communication nodes, and technical effects of the switching mode.

[0034] Figure 2 is a flowchart illustrating a measurement method in a handover mode according to an embodiment. As shown in Figure 2, the method provided in this embodiment is applicable to a first communication node (also referred to as a first communication node device, or a first node, or a first device), such as a UE. The method includes the following steps.

[0035] S210, when the first communication node is operating on multiple aggregated resources, receive the switching mode configuration configured by the second communication node. The switching mode configuration is used to instruct the first communication node to transmit signals on the first resource in a first time period and to transmit signals on the second resource in a second time period. The switching mode configuration includes at least the configuration of the switching period.

[0036] To increase the throughput of a wireless communication system, a second communication node can be configured to operate on multiple aggregated resources, similar to the first communication node. These resources can be aggregated using either a convergent aggregation (CA) or a delta convergence (DC) method. Each resource corresponds to a specific frequency bandwidth, and these bandwidths may or may not overlap.

[0037] In one embodiment, the resources can be cells or carriers / frequency bands. That is, the first communication node operates on multiple cells aggregated in a CA or DC manner, or on multiple frequency bands aggregated in a CA or DC manner.

[0038] In one embodiment, different resources may use the same duplexing mode, or different resources may use different duplexing modes. The duplexing mode includes at least one of the following: Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), Supplementary Downlink (SDL), Supplementary Uplink (SUL), etc.

[0039] For example, one resource (cell 1 or frequency band 1) has a duplex mode of FDD, and another resource (cell 2 or frequency band 2) has a duplex mode of SDL; one resource (cell 1 or frequency band 1) has a duplex mode of FDD, and another resource (cell 2 or frequency band 2) has a duplex mode of FDD; one resource (cell 1 or frequency band 1) has a duplex mode of TDD, and another resource (cell 2 or frequency band 2) has a duplex mode of FDD; one resource (cell 1 or frequency band 1) has a duplex mode of TDD, and another resource (cell 2 or frequency band 2) has a duplex mode of SDL; one resource (cell 1 or frequency band 1) has a duplex mode of TDD, and another resource (cell 2 or frequency band 2) has a duplex mode of TDD.

[0040] Figure 3 is a schematic diagram of a handover mode configuration provided in one embodiment. As shown in Figure 3, the handover mode configuration instructs the first communication node to transmit signals on the first resource during the first time period T1 and on the second resource during the second time period T2. That is, the antenna or radio frequency resources of the first communication node are used on the first resource during T1 and on the second resource during T2. For example, the handover mode configuration can be a receive switching pattern (Rx switching pattern). The handover mode configuration includes at least the configuration of the handover period. There is a guard interval GP between the first resource and the second resource. The guard interval GP may be configured with explicit signaling or may not be configured with explicit signaling, but may be implicitly determined by indicators such as radio frequency switching or switching transition time. When the GP is determined in an implicit manner, the time periods T1 and T2 may contain one or two GP durations. In this case, the following scheme does not need to consider the GP length between the first resource and the second resource, and only the time periods T1 and T2 need to be considered. For example, the embodiments of this disclosure use explicit signaling configuration of GP as an example, that is, the GP length needs to be considered separately for explanation.

[0041] Since resources can be cells or carriers / frequency bands, when the resource is a cell, the first cell is a PCell, a Primary Secondary Cell (PSCell), or an SCell, and the second cell is an SCell. When the resource is a frequency band, the first frequency band is the one configured with a PCell, PSCell, or SCell, and the second frequency band is another frequency band configured with an SCell. Here, the second frequency band defined as another frequency band configured with an SCell refers to a frequency band that is different from the first frequency band defined as a frequency band configured with an SCell.

[0042] The signal transmission performed by the first communication node on the first resource is the reception of downlink signals and / or the transmission of uplink signals; the signal transmission performed by the first communication node on the second resource is the reception of downlink signals and / or the transmission of uplink signals.

[0043] For example, the signal transmission performed by the first communication node on the first resource is the reception of downlink signals, and the signal transmission performed by the first communication node on the second resource is the reception of downlink signals; or, the signal transmission performed by the first communication node on the first resource is the reception of downlink signals and the transmission of uplink signals, and the signal transmission performed by the first communication node on the second resource is the reception of downlink signals; or, the signal transmission performed by the first communication node on the first resource is the transmission of uplink signals, and the signal transmission performed by the first communication node on the second resource is the reception of downlink signals.

[0044] S220. Measure the target resources according to the switching mode configuration.

[0045] Based on the handover mode configuration of the second communication node, the first communication node can measure the target resource. In one embodiment, the target resource can be a first resource, a second resource, or other resources besides the first and second resources (such as neighboring cell resources, inter-frequency resources, etc.).

[0046] The following examples illustrate the functions that the first communication node can achieve in switching modes.

[0047] Example 1: When the first communication node transmits a signal on the first resource during the first time period T1, how does the first communication node determine whether the second resource is in an inactive state or an active state at this time?

[0048] The first communication node determines that the second resource is inactive if at least one of the following conditions is met:

[0049] Within the first time period and the protection interval;

[0050] The first time period is greater than the first threshold, and it is within the first time period or within the first time period and the protection interval;

[0051] The first percentage is greater than the second threshold, and occurs within the first time period or within the first time period and the protection interval; the first percentage is equal to the ratio of the duration of the first time period to the switching cycle, or the first percentage is equal to the ratio of the duration of the first time period to the sum of the duration of the first time period and the duration of the second time period.

[0052] The second time period is less than or equal to the third threshold, and is within the first time period or within the first time period and the protection interval;

[0053] The second percentage is less than or equal to the fourth threshold, and is within the first time period or within the first time period and the protection interval; the second percentage is equal to the ratio of the duration of the second time period to the switching cycle, or the second percentage is equal to the ratio of the duration of the second time period to the sum of the duration of the first time period and the duration of the second time period.

[0054] For example, assuming the first communication node is UE, the first resource is PCell and the second resource is SCell, when the UE transmits signals on PCell in T1, the UE can determine whether SCell is in an inactive state or an active state in the following way.

[0055] Method 1-1) The UE considers the SCell to be inactive within T1 and GP; otherwise, the UE determines when the SCell is active and when it is inactive based on the legacy method.

[0056] (Method 1-2) The UE compares T1 with the first threshold. When the duration of T1 is not greater than the first threshold, the UE determines when the SCell is in an active state and when it is in an inactive state according to the legacy method; when the duration of T1 is greater than the first threshold, the UE considers that the SCell is in an inactive state within T1 or T1+GP.

[0057] (Methods 1-3) The UE determines the first proportion (i.e., the ratio of T1 duration to the switching periodicity; or the ratio of T1 duration to the sum of T1 duration and T2 duration, i.e., T1 / (T1+T2), and then compares the first proportion with the second threshold. When the first proportion is not greater than the second threshold, the UE determines when the SCell is in an active state and when it is in an inactive state according to the legacy method; when the first proportion is greater than the second threshold, the UE considers that the SCell is in an inactive state within T1 or T1+GP.

[0058] (Methods 1-4) The UE compares T2 with the third threshold. When the duration of T2 is greater than the third threshold, the UE determines when the SCell is in an active state and when it is in an inactive state according to the legacy method; when the duration of T2 is less than or equal to the third threshold, the UE considers that the SCell is in an inactive state within T1 or T1+GP.

[0059] (Methods 1-5) The UE determines the second proportion (i.e., the ratio of T2 duration to the switching periodicity; or the ratio of T2 duration to the sum of T1 duration and T2 duration, i.e., T2 / (T1+T2), and then compares the second proportion with the fourth threshold. When the second proportion is greater than the fourth threshold, the UE determines when the SCell is in an active state and when it is in an inactive state according to the legacy method; when the second proportion is less than or equal to the fourth threshold, the UE considers that the SCell is in an inactive state within T1 or T1+GP.

[0060] In one embodiment, the first threshold, the second threshold, the third threshold, and the fourth threshold are predefined by the system, or are semi-statically configured by the second communication node through Radio Resource Control (RRC) signaling.

[0061] Example 2: How to determine the active DL BWP when the first communication node determines whether same-frequency or different-frequency measurement needs to be performed with the help of a gap.

[0062] An active DL BWP on the first and / or second resource is determined based on at least one of the following:

[0063] When the first communication node transmits a signal on the first resource during the first time period, the active DL BWP on the second resource is determined based on the active DL BWP at the last moment of the previous second time period.

[0064] Determined based on the active DL BWP configured according to RRC signaling.

[0065] In one embodiment, the active DL BWP configured by the RRC signaling is either the first active DL BWP or the initial DL BWP.

[0066] In one embodiment, the RRC signaling configuration default active downlink bandwidth portion (DL BWP) is active DL BWP, and the RRC signaling is indicated by at least one of the following: included in the most recent RRC reconfiguration message; included in the most recent signaling for activating or deactivating the second resource; included in the most recent RRC signaling for configuring switching related parameters.

[0067] For example, assuming the first communication node is UE, the first resource is PCell, and the second resource is SCell, when the UE determines whether the same-frequency measurement or different-frequency measurement on SCell needs to be performed with the help of gap in T1, or when it determines whether the same-frequency measurement or different-frequency measurement on PCell needs to be performed with the help of gap in T2, the active DL BWP is determined in the following way.

[0068] Method 2-1) When the UE performs signal transmission on the PCell in T1, the UE determines the active DL BWP on the SCell based on the active DL BWP at the last moment in the previous T2. That is, the UE determines which BWP is the active DL BWP at the last moment in the previous T2, and then can use that BWP as the active DL BWP of the SCell in T1 to determine whether the Layer 3 (L3) RS is wrapped by the active DL BWP in the frequency domain, thereby determining whether the L3 measurement needs to be performed with the help of the gap.

[0069] When the UE transmits signals on the SCell in T2, the UE does not need to assume the active DL BWP on the SCell, because it is actually in use and can directly obtain the active DL BWP.

[0070] Method 2-2) The UE determines the active DL BWP based on the RRC signaling configuration.

[0071] For example, the UE determines the first active DL BWP based on the existing RRC signaling configuration. That is, it is assumed that the BWP configured in the existing RRC signaling configuration is the active DL BWP. This RRC signaling can be included in the most recent RRC reconfiguration message.

[0072] For example, the UE determines the BWP based on the existing RRC signaling configuration's initial DL BWP. That is, it is assumed that the existing RRC signaling configuration's initial active DL BWP is configured as an active DL BWP.

[0073] For example, the UE configures the default active DL BWP to the active DL BWP based on a newly introduced RRC signaling. The newly introduced RRC signaling is indicated by at least one of the following methods: included in the most recent RRC reconfiguration message; included in the most recent signaling for activating or deactivating a SCell; or included in the most recent RRC signaling for configuring handover-related parameters.

[0074] Once the UE determines the frequency domain resource range included in the active DL BWP based on the above method, it can further determine whether intra-frequency or inter-frequency measurements need to be performed using a gap.

[0075] Example 3: When the first communication node performs a measurement on the first resource within the first time period T1, how does the first communication node determine whether the measurement of the second resource should use the SSB-less SCell operation mode, that is, whether the first communication node needs to automatically switch to the SSB-less SCell operation mode?

[0076] The first communication node uses SSB-less SCell operation mode to measure the second resource if at least one of the following conditions is met:

[0077] The first and second resources are deployed at a shared site.

[0078] The frequency point or frequency band of the first and second resources is less than the preset threshold.

[0079] The first communication node supports SSB-less SCell capability for the frequency band combination where the first and second resources are located;

[0080] The second communication node is not configured with a measurement object (MO) on the second resource based on synchronization signals, SSB measurements, and / or Channel State Information-reference signals (CSI-RS).

[0081] In one embodiment, when the first communication node performs a measurement on the first resource within a first time period, at least one of the following conditions is met:

[0082] The first communication node determines whether to use the SSB-less SCell operation mode for measuring the second resource based on the explicit indication from the second communication node via dedicated RRC configuration signaling.

[0083] The first communication node determines whether to use the SSB-less SCell operation mode for measuring the second resource based on the implicit indication from the second communication node through other RRC configuration signaling.

[0084] For example, assuming the first communication node is a UE, the first resource is PCell, and the second resource is SCell, when the UE performs a measurement on PCell in T1, the UE can determine whether the measurement of SCell adopts the SSB-less SCell operation mode in the following way.

[0085] Method 3-1) The UE adopts the SSB-less SCell operation mode when at least one of the following conditions is met:

[0086] Condition 1: PCell and SCell are deployed at a shared site.

[0087] Condition 2: The frequency interval between the PCell and SCell frequencies or their respective frequency bands is less than a preset threshold.

[0088] When conditions 1 or 2 are met, the UE can assume that the RRC measurement results on the PCell frequency point are reused for the SCell frequency point, thereby avoiding the additional gap or interruption overhead incurred by the UE in performing SCell frequency point measurement within T1. That is, the UE adopts the SSB-less SCell operation mode.

[0089] Condition 3: The UE reports that it supports SSB-less SCell capability for the frequency band combination where the PCell and SCell are located.

[0090] Condition 4: The base station does not have an SSB configuration configured for L3 measurement or mobility measurement for the SCell (e.g., it could be an SSB-Based Measurement Timing Configuration (SMTC) or related configuration in the MO).

[0091] Condition 5: The base station does not have a CSI-RS configuration configured for L3 measurement or mobility measurement in the SCell (e.g., it could be a CSI-RS related configuration in the MO).

[0092] Method 3-2) The UE is explicitly or implicitly instructed via RRC configuration signaling whether to enable SSB-less SCell operation for SCell within T1, i.e., not to perform SSB based L3 measurement on SCell.

[0093] Explicit indication is provided by introducing dedicated RRC signaling to indicate whether the UE enables SSB-less SCell operation.

[0094] Implicit indication is used to indicate whether the UE enables SSB-less SCell operation via other RRC signaling.

[0095] Example 4: When the first communication node performs a measurement on the second resource during the second time period T2, how does the first communication node determine whether the measurement of the second resource adopts the SSB-less SCell operation mode, that is, whether the first communication node needs to automatically switch to the SSB-less SCell operation mode?

[0096] When the first communication node performs a measurement on the second resource during the second time period, at least one of the following conditions is met:

[0097] When the second communication node is configured with a measurement object MO based on SSB measurement on the second resource, the first communication node does not use the SSB-less SCell operation mode to measure the second resource.

[0098] When the second communication node is configured with an MO based on SSB measurement on the second resource, the first communication node determines whether the measurement of the second resource adopts the SSB-less SCell operation mode according to the explicit indication of the second communication node through RRC signaling.

[0099] When the second communication node is configured with an MO based on SSB measurement on the second resource, the first communication node determines whether to use the SSB-less SCell operation mode for the measurement of the second resource according to the SSB configuration and the switching mode configuration.

[0100] In the case where the second communication node is configured with an MO based on SSB measurement on the second resource, if the SSB occasion determined by the first communication node according to the SSB configuration falls within the second time period configured by the switching mode, the first communication node determines that the measurement of the second resource will not adopt the SSB-less SCell operation mode.

[0101] If the second communication node is configured with an MO based on SSB measurement on the second resource, and the SSB occasion determined by the first communication node according to the SSB configuration does not fall within the second time period configured by the switching mode, the first communication node determines that the measurement of the second resource adopts the SSB-less SCell operation mode.

[0102] When the second communication node is configured with an MO based on SSB measurement on the second resource, if some SSB occasions determined by the first communication node according to the SSB configuration fall within the second time period of the switching mode configuration, and other SSB occasions fall outside the second time period of the switching mode configuration or within the first time period, the first communication node determines that the measurement of the second resource adopts the SSB-less SCell operation mode.

[0103] For example, assuming the first communication node is a UE, the first resource is PCell, and the second resource is SCell, when the UE performs a measurement on the SCell in T2, the UE can determine whether the measurement of the SCell adopts the SSB-less SCell operation mode in the following way.

[0104] Method 4-1) As long as the base station configures MO based on SSB measurement on the SCell, the UE will always perform L3 measurement based on SSB on the SCell and will not enable SSB-less SCell operation mode.

[0105] (Method 4-2) Even if the base station configures SSB-based MO on the SCell, whether the UE performs SSB-based L3 measurement on the SCell is explicitly indicated to the UE by the base station through RRC signaling. This RRC signaling may be valid for both T1 and T2, or only for T2.

[0106] Method 4-3) If the base station has configured an SSB on the SCell, the decision on whether to perform SSB-based L3 measurements on the SCell is made based on the SSB configuration and the handover mode configuration. At least one of the following should be used:

[0107] If the SSB occasion, determined based on the SSB configuration (e.g., the SSB configuration period and / or SSB time-domain offset), falls within T2 of the switching pattern configuration, then an SSB-based L3 measurement is performed on the SCell.

[0108] If the SSB occasion determined based on the SSB configuration (e.g., the SSB configuration period and / or SSB time-domain offset) does not fall within T2 of the switching pattern configuration, then SSB-based L3 measurement is not performed on the SCell, and the L3 measurement result of the PCell is reused as the L3 measurement result of the SCell.

[0109] If some SSB occasions, determined by the SSB configuration (e.g., the SSB configuration period and / or SSB time-domain offset), fall within T2 of the switching pattern configuration, and other SSB occasions fall outside T2 or within T1 of the switching pattern configuration, then SSB-based L3 measurements are not performed on the SCell, and the L3 measurement results of the PCell are reused as the L3 measurement results of the SCell.

[0110] In Examples 3 and 4 above, when the first communication node adopts the SSB-less SCell operation mode for measuring the second resource, the first communication node does not perform SSB-based Layer 3 measurement for the second resource, but reuses the SSB-based L3 measurement result for the first resource as the SSB-based L3 measurement result for the second resource.

[0111] Example 5: When the first communication node performs a measurement on the first resource during the first time period T1, in order to reduce the interruption caused by the UE performing an L3 measurement on the second resource, at least one of the following methods shall be used for the L3 measurement of the second resource:

[0112] Based on capability indication information; capability indication information is used to indicate whether the first communication node is able to perform L3 measurement without gap or with short gap on the second resource when transmitting signals on the first resource in the first time period;

[0113] The L3 measurement of the second resource is relaxed.

[0114] In one embodiment, the measurement period corresponding to the measurement relaxation is at least one of the following: a discontinuous reception cycle (DRX cycle), a switching cycle, or the product of the inactive state measurement period of the second communication node for the second resource configuration and the relaxation factor.

[0115] In one embodiment, the second resource is in an active or inactive state; when the second resource is in an active state, the relaxation factor is 1; when the second resource is in an inactive state, the relaxation factor is a constant greater than or equal to 1.

[0116] For example, assuming the first communication node is a UE, the first resource is a PCell, and the second resource is a SCell, when the UE performs a measurement on the PCell in T1, for the L3 measurement of the activated SCell, in order to reduce the interruption caused by the UE performing the L3 measurement for the SCell, at least one of the following methods is used:

[0117] Method 5-1) introduces a new UE capability that indicates whether the UE can still perform L3 measurements without gap or with short gap on the L3 RS of the activated SCell during handover to the PCell. If the UE indicates to the base station that it supports this capability for a specific PCell, SCell band combination, or a specific band, it means that the UE can perform L3 measurements without gap or with short gap on the activated SCell during the T1 period of handover to the PCell. If the UE does not indicate this capability or indicates that it does not support this capability for a specific PCell, SCell band combination, or a specific band, it means that the UE can only perform L3 measurements with gap on the activated SCell of the specific band combination or specific band during the T1 period.

[0118] Method 5-2) relaxes the L3 measurement for SCell within T1, meaning the UE performs L3 measurements with a longer measurement period. A longer measurement period refers to a period longer than the SMTC period or CSI-RS period configured in the MO. At least one of the following is used:

[0119] If a DRX cycle is configured, the DRX cycle is used as the measurement cycle for performing L3 measurements on activated SCells within T1. If SSB-based L3 measurements are configured, the UE selects one occasion from all SSB occasions falling within the DRX ON period to perform L3 measurements on activated SCells. If CSI-RS-based L3 measurements are configured, the UE selects one occasion from all CSI-RS occasions falling within the DRX ON period to perform L3 measurements on activated SCells.

[0120] The switching pattern periodicity is used as the measurement cycle for performing L3 measurements on the activated state SCell within T1. If SSB-based L3 measurement is configured, the UE selects one occasion from all SSB occasions falling within T1 within each switching pattern periodicity to perform L3 measurements on the activated state SCell. If CSI-RS-based L3 measurement is configured, the UE selects one occasion from all CSI-RS occasions falling within T1 within each switching pattern periodicity to perform L3 measurements on the activated state SCell.

[0121] The UE uses the deactivated SCell measurement period `measCycleSCell` configured by the base station for this SCell to perform L3 measurements on the activated SCell within T1. If SSB-based L3 measurement is configured, the UE selects one occasion from all SSB occasions falling within T1 within each `measCycleSCell` duration to perform L3 measurements on the activated SCell. If CSI-RS-based L3 measurement is configured, the UE selects one occasion from all CSI-RS occasions falling within T1 within each `measCycleSCell` duration to perform L3 measurements on the activated SCell.

[0122] For example, assuming the first communication node is a UE, the first resource is a PCell, and the second resource is a SCell, when the UE performs a measurement on the PCell in T1, for the L3 measurement of the deactivated SCell, in order to reduce the interruption caused by the UE performing the L3 measurement for the SCell, at least one of the following methods is used:

[0123] Method 5-3) introduces a new UE capability that indicates whether the UE can still perform L3 measurements without gap or with short gap on the L3 RS of the deactivated SCell during handover to the PCell. If the UE indicates to the base station that it supports this capability for a specific PCell, SCell band combination, or a specific band, it means that the UE can perform L3 measurements without gap or with short gap on the deactivated SCell during T1 of handover to the PCell. If the UE does not indicate this capability or indicates that it does not support this capability for a specific PCell, SCell band combination, or a specific band, it means that the UE can only perform L3 measurements with gap on the deactivated SCell of the specific band combination or specific band during T1.

[0124] Method 5-4) relaxes L3 measurements for deactivated SCells within T1, meaning the UE performs L3 measurements with a longer measurement period. A longer measurement period refers to a period longer than the SMTC period or CSI-RS period configured in the MO. At least one of the following is used:

[0125] If a DRX cycle is configured, the DRX cycle is used as the measurement period for performing L3 measurements on deactivated SCells within T1. If SSB-based L3 measurements are configured, the UE selects one occasion from all SSB occasions falling within the DRX ON period to perform L3 measurements on deactivated SCells. If CSI-RS-based L3 measurements are configured, the UE selects one occasion from all CSI-RS occasions falling within the DRX ON period to perform L3 measurements on deactivated SCells.

[0126] The switching pattern periodicity is used as the measurement cycle for performing L3 measurements on deactivated SCells within T1. If SSB-based L3 measurements are configured, the UE selects one occasion from all SSB occasions falling within T1 within each switching pattern periodicity to perform L3 measurements on deactivated SCells. If CSI-RS-based L3 measurements are configured, the UE selects one occasion from all CSI-RS occasions falling within T1 within each switching pattern periodicity to perform L3 measurements on deactivated SCells.

[0127] The UE uses the base station's configured deactivated SCell measurement period `measCycleSCell` for this SCell, and introduces a relaxation factor `f`, using `f*measCycleSCell` as the measurement period to perform L3 measurements on the deactivated SCell within T1. Here, `f` is a constant greater than or equal to 1, predefined by the system or semi-statically configured by the base station. If SSB-based L3 measurement is configured, the UE selects one occasion from all SSB occasions falling within T1 within each `f*measCycleSCell` duration to perform L3 measurements on the deactivated SCell. If CSI-RS-based L3 measurement is configured, the UE selects one occasion from all CSI-RS occasions falling within T1 within each `f*measCycleSCell` duration to perform L3 measurements on the deactivated SCell.

[0128] Example 6: For a multi-carrier application scenario with a switching mode configuration, how should the first communication node execute the second resource activation process? At least one of the following must be satisfied:

[0129] The first communication node performs only the SSB measurement or the tracking reference signal TRS measurement required for the second resource activation process during the second time period.

[0130] The first communication node can perform the SSB measurement or TRS measurement required for the second resource activation process during both the first and second time periods.

[0131] In one embodiment, when the first communication node performs the SSB measurement or TRS measurement required for the second resource activation process only during the second time period, the baseband resources applied to the second resource during the measurement process are preferentially allocated to the measurement, and the carrier-specific scaling factor (CSSF) corresponding to the measurement is set to 1.

[0132] When the first communication node can perform the SSB measurement or TRS measurement required for the second resource activation process during both the first and second time periods, the baseband resources applied to the second resource during the measurement process are preferentially allocated to the measurement, and the CSSF value corresponding to the measurement is 1.

[0133] For example, assuming the first communication node is a UE, the first resource is a PCell, and the second resource is a SCell, when the UE performs SCell activation, it needs to perform one or more measurements based on the SSB or TRS on the SCell, using at least one of the following methods:

[0134] Method 6-1) The UE only performs the SSB or TRS measurements required for the SCell activation process within T2. ​​When the SSB or TRS period is long, the UE may not complete the entire SCell activation process within one T2. In this case, the UE performs multiple SSB or TRS measurements discontinuously within T2 of multiple switching pattern periodicities to complete the SCell activation process. For SCell SSB or SCell TRS occasions falling within period T1, the UE does not perform the measurements required for SCell activation. In this method, the entire SCell activation process takes a long time, but no gap is needed.

[0135] (Method 6-2) The UE can perform the SSB or TRS measurements required for the SCell activation process within both time periods T2 and T1. When the SSB or TRS period is large, the UE may not be able to complete the entire SCell activation process within one T1+T2 period. In this case, the UE will perform multiple SSB or TRS measurements continuously or discontinuously within multiple switching pattern periodicities of T1+T2 to complete the SCell activation process. The SCell SSB or SCell TRS measurements performed by the UE within T2 do not require a gap. The SCell SSB or SCell TRS measurements performed by the UE within T1 require a gap.

[0136] Regardless of whether it is method 6-1) or method 6-2), when the UE performs SCell SSB measurement or SCell TRS measurement without the need for gap in T2, if the UE has other same-frequency or different-frequency measurements that do not need to be performed, in order to ensure that the SCell activation process delay is as small as possible, the baseband resources (searcher) available for SCell are preferentially allocated to the SCell SSB measurement or SCell TRS measurement during the SCell activation process.

[0137] Example 7: After the switching mode configuration is enabled, the first communication node uses one or more baseband resources to measure the primary component carrier (PCC) frequency point in the first time period, and uses one or more baseband resources to measure the secondary component carrier (SCC) frequency point in the second time period.

[0138] When the first communication node uses multiple baseband resources to perform SCC frequency point measurements during the second time period, at least one of the following allocation methods shall be used:

[0139] At least one baseband resource is used for SSB-based measurements at the SCC frequency, and another baseband resource is used for CSI-RS-based measurements at the SCC frequency, as well as other inter-frequency MO measurements without gap, and inter-RAT MO measurements for interoperability between different wireless access technologies.

[0140] At least one baseband resource is used for SCell measurements at the SCC frequency, and another baseband resource is used for neighboring cell measurements at the SCC frequency, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0141] At least one baseband resource is used for SCC frequency point measurement with neighbor cell measurement requirements, and another baseband resource is used for measurement of one or more other SCC frequency points without neighbor cell measurement requirements, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0142] At least one baseband resource is used for high-priority SCC frequency point measurements, and another baseband resource is used for the remaining SCC frequency point measurements as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0143] For example, when switching pattern configuration is enabled, the UE receives the alignment PCell in T1 and the alignment SCell in T2, which will affect how traditional CSSF calculations and baseband resources (searchers) used by the UE to perform measurements are allocated.

[0144] For traditional UEs, it is generally assumed that the UE has 2 or 3 searchers for performing gapless Radio Resource Management (RRM) measurements. The typical searcher allocation principle is as follows: Under CA (Carrier Controller), one searcher is dedicated to PCC (Potentially Differential Control) measurements, and the other searcher is shared for SCC (Single-Frequency Control), inter-frequency gapless measurements, and inter-RAT gapless measurements. Under DC (Digital Control), one searcher is dedicated to PCC measurements, and the other searcher is shared for PSCC (Personalized Switched Control), SCC, inter-frequency gapless measurements, and inter-RAT gapless measurements.

[0145] For traditional UE with gap RRM measurement, the UE can only perform with gap RRM measurement on one frequency point or MO at a time.

[0146] Therefore, after enabling the switching pattern configuration, the UE may be unable to perform gap-free measurements on SCC or other inter-frequency MOs or inter-RAT MOs within T1. The UE could then use two or three searchers for measurements on the PCC frequency, for example, one searcher for SSB-based measurements on the PCC frequency and another for CSI-RS-based measurements on the PCC frequency. Consequently, a new calculation method for the CSSF factor is needed.

[0147] Accordingly, within T2, the UE can use two or three searchers for SCC frequency point measurements, and can adopt at least one of the following allocation methods:

[0148] Method 7-1) Use one searcher for SSB-based measurements at the SCC frequency point, and another searcher for CSI-RS-based measurements at the SCC frequency point, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0149] Method 7-2) Use one searcher for SCell measurements at the SCC frequency point, and another searcher for neighbor cell measurements at the SCC frequency point, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0150] Method 7-3) Use one searcher for SCC 1 frequency point measurement where there is a need for neighboring cell measurement at the SCC frequency point, and use another searcher for measurement of one or more other SCC frequency points where there is no need for neighboring cell measurement at the SCC frequency point, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0151] Method 7-4) Use one searcher for high-priority SCC frequency point measurements and another searcher for all other SCC frequency point measurements as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0152] Method 7-5) The allocation principle for the third or more searchers can be the same as that for the first searcher.

[0153] Figure 4 is a flowchart illustrating a configuration method for switching modes according to an embodiment. As shown in Figure 4, the method provided in this embodiment is applicable to a second communication node (also referred to as a second communication node device, or a second node, or a second device), such as a base station. The method includes the following steps.

[0154] S410, when the first communication node is operating on multiple aggregated resources, configure a switching mode configuration for the first communication node. The switching mode configuration is used to instruct the first communication node to transmit signals on the first resource in a first time period and to transmit signals on the second resource in a second time period. The switching mode configuration includes at least the configuration of the switching period.

[0155] To increase the throughput of a wireless communication system, a second communication node can be configured to operate on multiple aggregated resources, similar to the first communication node. These resources can be aggregated using either a convergent aggregation (CA) or a delta convergence (DC) method. Each resource corresponds to a specific frequency bandwidth, and these bandwidths may or may not overlap.

[0156] In one embodiment, the resources can be cells or carriers / frequency bands. That is, the first communication node operates on multiple cells aggregated in a CA or DC manner, or on multiple frequency bands aggregated in a CA or DC manner.

[0157] In one embodiment, different resources may use the same duplex mode, or different resources may use different duplex modes. The duplex mode includes at least one of the following: FDD, TDD, SDL, SUL, etc.

[0158] For example, one resource (cell 1 or frequency band 1) has a duplex mode of FDD, and another resource (cell 2 or frequency band 2) has a duplex mode of SDL; one resource (cell 1 or frequency band 1) has a duplex mode of FDD, and another resource (cell 2 or frequency band 2) has a duplex mode of FDD; one resource (cell 1 or frequency band 1) has a duplex mode of TDD, and another resource (cell 2 or frequency band 2) has a duplex mode of FDD; one resource (cell 1 or frequency band 1) has a duplex mode of TDD, and another resource (cell 2 or frequency band 2) has a duplex mode of SDL; one resource (cell 1 or frequency band 1) has a duplex mode of TDD, and another resource (cell 2 or frequency band 2) has a duplex mode of TDD.

[0159] The handover mode configuration instructs the first communication node to transmit signals on the first resource during a first time period T1 and on the second resource during a second time period T2. That is, the antenna or radio frequency resources of the first communication node are used on the first resource during T1 and on the second resource during T2. For example, the handover mode configuration could be a receive switching pattern (Rx switching pattern). The handover mode configuration includes at least the configuration of the handover period. There is a guard interval GP between the first and second resources. The guard interval GP may or may not be configured explicitly via signaling, but may be implicitly determined by indicators such as radio frequency switching or switching transition time.

[0160] Since resources can be cells or carriers / frequency bands, when the resource is a cell, the first cell is a PCell, a primary PSCell, or a SCell, and the second cell is a SCell. When the resource is a frequency band, the first frequency band is the one configured with a PCell, PSCell, or SCell, and the second frequency band is another frequency band configured with a SCell. Here, the definition of the second frequency band as another frequency band configured with a SCell refers to a frequency band that is distinct from the frequency band configured with a SCell defined in the first frequency band.

[0161] In one embodiment, the second communication node configures at least one of the following to the first communication node;

[0162] The active DL BWP is configured via RRC signaling. In one implementation, the active DL BWP configured by RRC signaling is either the first active DL BWP or the initial DL BWP. In another implementation, the default active DL BWP is configured as the active DL BWP by RRC signaling, indicated by at least one of the following: included in the most recent RRC reconfiguration message; included in the most recent signaling that activates or deactivates the second resource; or included in the most recent RRC signaling that configures the switching parameters.

[0163] The first communication node is explicitly instructed via dedicated RRC configuration signaling whether to use the non-synchronization signal transmission and physical broadcast channel block (SSB-less SCell) operation mode for measuring the second resource.

[0164] The first communication node implicitly indicates through other RRC configuration signaling whether it uses SSB-less SCell operation mode to measure the second resource.

[0165] In one embodiment, the second communication node can also semi-statically configure a first threshold, a second threshold, a third threshold, and a fourth threshold to the first communication node via RRC signaling. The specific uses of the first to fourth thresholds can be found in the description of the above embodiments, and will not be repeated here for the sake of brevity.

[0166] In one embodiment, the second communication node may also configure an inactive measurement period for the second resource.

[0167] In one embodiment, the second communication node is configured with an MO based on SSB measurement and / or CSI-RS measurement on the second resource.

[0168] Figure 5 is a schematic diagram of a measurement device in a switching mode according to an embodiment. The device can be configured in a first communication node. As shown in Figure 5, the device includes a first communication module 501 and a measurement module 502.

[0169] The first communication module 501 is configured to receive a switching mode configuration configured by the second communication node when the first communication node is working on multiple aggregated resources. The switching mode configuration is used to instruct the first communication node to transmit signals on the first resource in a first time period and to transmit signals on the second resource in a second time period. The switching mode configuration includes at least a switching period configuration.

[0170] Measurement module 502 is configured to measure the target resource according to the switching mode configuration.

[0171] The measuring device in the switching mode provided in this embodiment is to implement the measuring method in the switching mode of the embodiment shown in FIG2. The implementation principle and technical effect of the measuring device in the switching mode provided in this embodiment are similar to those of the above embodiments, and will not be repeated here.

[0172] In one embodiment, different resources may have the same duplex mode, or different resources may have different duplex modes;

[0173] The duplex mode includes at least one of the following: frequency division duplex (FDD), time division duplex (TDD), supplementary downlink (SDL), and supplementary uplink (SUL).

[0174] In one embodiment, the signal transmission performed by the first communication node on the first resource is the reception of downlink signals and / or the transmission of uplink signals;

[0175] The signal transmission performed by the first communication node on the second resource is the reception of downlink signals and / or the transmission of uplink signals.

[0176] In one embodiment, the resource is a cell or a frequency band.

[0177] In one embodiment, when the resource is a cell, the first cell is a primary cell PCell, a primary secondary cell PSCell, or a secondary cell SCell, and the second cell is an SCell;

[0178] When the resource is a frequency band, the first frequency band is the one configured with PCell, PSCell, or SCell, and the second frequency band is another frequency band configured with SCell.

[0179] In one embodiment, when the first communication node transmits a signal on the first resource during a first time period, the second resource is inactive if at least one of the following conditions is met:

[0180] Within the first time period and the protection interval;

[0181] The first time period is greater than the first threshold, and it is within the first time period or within the first time period and the protection interval;

[0182] The first percentage is greater than the second threshold, and occurs within the first time period or within the first time period and the protection interval; the first percentage is equal to the ratio of the duration of the first time period to the switching cycle, or the first percentage is equal to the ratio of the duration of the first time period to the sum of the duration of the first time period and the duration of the second time period.

[0183] The second time period is less than or equal to the third threshold, and is within the first time period or within the first time period and the protection interval;

[0184] The second percentage is less than or equal to the fourth threshold, and is within the first time period or within the first time period and the protection interval; the second percentage is equal to the ratio of the duration of the second time period to the switching cycle, or the second percentage is equal to the ratio of the duration of the second time period to the sum of the duration of the first time period and the duration of the second time period.

[0185] In one embodiment, the first threshold, the second threshold, the third threshold, and the fourth threshold are predefined by the system, or are semi-statically configured by the second communication node through Radio Resource Control (RRC) signaling.

[0186] In one embodiment, the active downlink bandwidth portion (active DL BWP) on the first resource and / or the second resource is determined according to at least one of the following:

[0187] When the first communication node transmits a signal on the first resource during the first time period, the active DL BWP on the second resource is determined based on the active DL BWP at the last moment of the previous second time period.

[0188] Determined based on the active DL BWP configured according to RRC signaling.

[0189] In one embodiment, the active DL BWP configured by the RRC signaling is either the first active DL BWP or the initial DL BWP.

[0190] In one embodiment, the RRC signaling configures the default active DL BWP to be the active DL BWP, and the RRC signaling indicates this through at least one of the following:

[0191] Included in the most recent RRC reconfiguration message;

[0192] Included in the signaling of the most recent activation or deactivation of the second resource;

[0193] It is included in the RRC signaling of the most recent configuration switch-related parameters.

[0194] In one embodiment, when the first communication node performs a measurement on the first resource within a first time period, the first communication node uses a no-synchronization-signal and physical broadcast channel block (SSB-less SCell) operation mode for the measurement of the second resource if at least one of the following conditions is met:

[0195] The first and second resources are deployed at a shared site.

[0196] The frequency point or frequency band of the first and second resources is less than the preset threshold.

[0197] The first communication node supports SSB-less SCell capability for the frequency band combination where the first and second resources are located;

[0198] The second communication node is not configured on the second resource to measure the object MO based on synchronization signals and physical broadcast channel block (SSB) measurements and / or channel state information reference signals (CSI-RS).

[0199] In one embodiment, when the first communication node performs a measurement on the first resource within a first time period, at least one of the following conditions is met:

[0200] The first communication node determines whether to use the SSB-less SCell operation mode for measuring the second resource based on the explicit indication from the second communication node via dedicated RRC configuration signaling.

[0201] The first communication node determines whether to use the SSB-less SCell operation mode for measuring the second resource based on the implicit indication from the second communication node through other RRC configuration signaling.

[0202] In one embodiment, when the first communication node performs a measurement on the second resource during a second time period, at least one of the following conditions is met:

[0203] When the second communication node is configured with a measurement object MO based on SSB measurement on the second resource, the first communication node does not use the SSB-less SCell operation mode to measure the second resource.

[0204] When the second communication node is configured with an MO based on SSB measurement on the second resource, the first communication node determines whether the measurement of the second resource adopts the SSB-less SCell operation mode according to the explicit indication of the second communication node through RRC signaling.

[0205] When the second communication node is configured with an MO based on SSB measurement on the second resource, the first communication node determines whether to use the SSB-less SCell operation mode for the measurement of the second resource according to the SSB configuration and the switching mode configuration.

[0206] In one embodiment, when the second communication node is configured with an MO based on SSB measurement on the second resource, if the SSB occasion determined by the first communication node according to the SSB configuration falls within the second time period configured by the switching mode, the first communication node determines that the measurement of the second resource will not adopt the SSB-less SCell operation mode.

[0207] If the second communication node is configured with an MO based on SSB measurement on the second resource, and the SSB occasion determined by the first communication node according to the SSB configuration does not fall within the second time period configured by the switching mode, the first communication node determines that the measurement of the second resource adopts the SSB-less SCell operation mode.

[0208] When the second communication node is configured with an MO based on SSB measurement on the second resource, if some SSB occasions determined by the first communication node according to the SSB configuration fall within the second time period of the switching mode configuration, and other SSB occasions fall outside the second time period of the switching mode configuration or within the first time period, the first communication node determines that the measurement of the second resource adopts the SSB-less SCell operation mode.

[0209] In one embodiment, when the first communication node uses the SSB-less SCell operation mode to measure the second resource, the first communication node does not perform SSB-based Layer 3 measurement for the second resource, but reuses the SSB-based L3 measurement result for the first resource as the SSB-based L3 measurement result for the second resource.

[0210] In one embodiment, when the first communication node performs a measurement on the first resource within a first time period, the L3 measurement of the second resource employs at least one of the following methods:

[0211] Based on capability indication information; capability indication information is used to indicate whether the first communication node is able to perform L3 measurement without gap or with short gap on the second resource when transmitting signals on the first resource in the first time period;

[0212] The L3 measurement of the second resource is relaxed.

[0213] In one embodiment, the measurement period corresponding to the measurement relaxation is at least one of the following: a discontinuous reception period (DRX cycle), a switching period, or the product of the inactive state measurement period of the second communication node for the second resource configuration and the relaxation factor.

[0214] In one embodiment, the second resource is either in an active state or an inactive state;

[0215] When the second resource is in an active state, the relaxation factor takes the value of 1;

[0216] When the second resource is inactive, the relaxation factor is a constant greater than or equal to 1.

[0217] In one embodiment, at least one of the following is satisfied:

[0218] The first communication node performs only the SSB measurement or the tracking reference signal TRS measurement required for the second resource activation process during the second time period.

[0219] The first communication node can perform the SSB measurement or TRS measurement required for the second resource activation process during both the first and second time periods.

[0220] In one embodiment, when the first communication node performs the SSB measurement or TRS measurement required for the second resource activation process only during the second time period, the baseband resources applied to the second resource during the measurement process are preferentially allocated to the measurement, and the carrier-specific scaling factor (CSSF) corresponding to the measurement is 1.

[0221] When the first communication node can perform the SSB measurement or TRS measurement required for the second resource activation process during both the first and second time periods, the baseband resources applied to the second resource during the measurement process are preferentially allocated to the measurement, and the CSSF value corresponding to the measurement is 1.

[0222] In one embodiment, after the switching mode configuration is enabled, the first communication node uses one or more baseband resources to perform main component carrier PCC frequency point measurement in a first time period and uses one or more baseband resources to perform auxiliary component carrier SCC frequency point measurement in a second time period.

[0223] In one embodiment, when the first communication node performs SCC frequency point measurement using multiple baseband resources during a second time period, at least one of the following allocation methods is used:

[0224] At least one baseband resource is used for SSB-based measurements at the SCC frequency, and another baseband resource is used for CSI-RS-based measurements at the SCC frequency, as well as other inter-frequency MO measurements without gap, and inter-RAT MO measurements for interoperability between different wireless access technologies.

[0225] At least one baseband resource is used for SCell measurements at the SCC frequency, and another baseband resource is used for neighboring cell measurements at the SCC frequency, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0226] At least one baseband resource is used for SCC frequency point measurement with neighbor cell measurement requirements, and another baseband resource is used for measurement of one or more other SCC frequency points without neighbor cell measurement requirements, as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0227] At least one baseband resource is used for high-priority SCC frequency point measurements, and another baseband resource is used for the remaining SCC frequency point measurements as well as other inter-frequency MO and inter-RAT MO measurements without gap.

[0228] Figure 6 is a schematic diagram of a configuration device for switching modes provided in an embodiment. The device can be configured in a second communication node. As shown in Figure 6, the device includes a second communication module 601.
