Description

Technical Field

[0001] This application relates to the field of communication technologies, for example, measurement in a handover mode, a configuration method for the handover mode, a node, and a medium. Background Art

[0002] In a wireless communication system, there is a trade-off relationship between the gain of an antenna and the fractional bandwidth, because better radiation characteristics in a specific direction will limit the bandwidth size. In some Carrier Aggregation (CA) or Dual Connectivity (DC) combinations, due to limitations in antenna size and cost considerations of communication nodes, the same antenna or radio frequency resource may be used for signal transmission of multiple frequency bands / carriers. However, to ensure a certain antenna gain, the fractional bandwidth of the antenna needs to not exceed a certain empirical value, resulting in limited antenna radiation bandwidth and potentially unable to cover multiple member frequency bands / carriers. By using a switching method (such as transmitting antenna switching, receiving antenna switching, transmitting radio frequency resource switching, receiving radio frequency resource switching), the same antenna or radio frequency resource can be applied to multiple frequency bands / carriers in a time-division manner. However, introducing the above methods in the current wireless communication system will affect the process of resource measurement. Summary of the Invention

[0019] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0020] To support the wireless signal coverage of different frequency bands, multiple antennas are deployed on communication nodes (such as terminal devices, access network devices, etc.) to cover the signal transmissions of low-frequency bands, medium-frequency bands, and high-frequency bands. The bandwidth coverage capabilities of different types of antennas are different, and the fractional bandwidth is usually used to describe the performance stability of the antenna at different frequencies. For any type of antenna, there is a trade-off relationship between its gain and fractional bandwidth: high-gain antennas are often designed to be narrower and have a smaller fractional bandwidth; while broadband antennas usually have a lower antenna gain because better radiation characteristics in a specific direction will limit the bandwidth size.

[0021] In some CA or DC combinations, limited by antenna size and cost considerations of terminal devices, the same antenna or radio frequency resource may be used for signal transmission in multiple frequency bands / carriers. However, to ensure a certain antenna gain, the fractional bandwidth of the antenna needs to not exceed a certain empirical value, resulting in limited antenna radiation bandwidth and potentially an inability to cover multiple member frequency bands / carriers. Therefore, a switching method (such as transmit antenna switching, receive antenna switching, transmit radio frequency resource switching, receive radio frequency resource switching) needs to be introduced to enable the same antenna or radio frequency 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:

[0022] 1) It affects the activation / deactivation process of resources.

[0023] For example, in the existing activation / deactivation process of a Secondary Cell (SCell), the terminal device needs to perform several measurements on the synchronization signal and 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. And these measurements based on SSB or TRS do not require the aid of a gap. However, after introducing receive switching between the Primary Cell (PCell) and at least one SCell, considering that the terminal device switches to the PCell for reception during certain time periods, how the terminal device ensures the trade-off between the SCell activation delay and the interruption caused by the measurements based on SSB or TRS during the SCell activation process is an issue that needs to be solved currently.

[0024] 2) It affects co-frequency measurement or inter-frequency measurement.

[0025] Whether the same-frequency measurement or the inter-frequency measurement needs to be performed with the help of a gap is related to whether the reference signal (RS) configuration on the frequency to be measured is completely covered by the active downlink bandwidth part (active DL BWP) of the current serving cell in the frequency domain. If the RS configuration on the frequency to be measured can be completely covered by the active DL BWP of the current serving cell, the measurement can be performed without the help of a gap, that is, without-gap measurement. On the contrary, the measurement needs to be performed with the help of a gap, that is, with-gap measurement. Then, when determining whether it is a without-gap or with-gap measurement, the assumption of the active DL BWP on the PCell or SCell is crucial. However, after introducing the receive handover between the PCell and at least one SCell, how to determine the active DL BWP is also a problem to be solved.

[0026] 3) Considering that legacy technology already supports SSB-less SCell operation in co-located deployment, in the scenario where receive handover is introduced, it is also a problem to be solved whether the terminal device performs SSB-less SCell operation or SSB-based measurement operation on the SCell.

[0027] The measurement method in the handover mode and the configuration method of the handover mode provided in this application 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 the future development of communication, such as 6th-generation (6G) systems, etc. Figure 1 It is a schematic diagram of the networking of a wireless communication system provided by an embodiment. As Figure 1 shown, the wireless communication system includes a terminal device 110, an access network device 120, and a core network device 130.

[0028] The terminal device 110 can be a device with wireless transceiver functions, which can be deployed on land (such as indoors or outdoors, handheld, wearable or vehicle-mounted, etc.); it can also be deployed on water (such as a ship, etc.); it can also be deployed in the air (such as an airplane, a balloon, a satellite, etc.). Some examples of the terminal device 110 are: a non-powered terminal, a user equipment (UE), a mobile phone, a mobile station, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a personal digital assistant (PDA), and other connectable user devices, or a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc., or an Internet of Things node in the Internet of Things, or a vehicle-mounted communication device in a vehicle-to-everything network, or an entertainment or gaming device or system, or a global positioning system device, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device. In addition, the terminal device can be abbreviated as the terminal.

[0029] The access network device 120 is an access device for the terminal device 110 to access the wireless communication system in a wireless manner. It can be a reader, a base station, an evolved NodeB (eNB or eNodeB) in Long Term Evolution Advanced (LTEA), a transmission reception point (TRP), a base station in a 5G mobile communication system or a next generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a Wireless Fidelity (WiFi) system, etc. The base station can include various macro base stations, micro base stations, home base stations, remote radio heads, routers, WIFI devices, or various network-side devices such as PCell and SCell, and location management function (LMF) devices. It can also be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU) or a distributed unit (DU). The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the access network device. In addition, the access network device can be abbreviated as the base station.

[0030] The core network device 130 can include an access and mobility management network element and a session management network element. Exemplarily, the terminal device 110 can access the core network through the access network device 120 to achieve data transmission.

[0031] In the embodiments of the present application, a measurement method, a configuration method for a handover mode, a node, and a medium that can operate in the handover mode of the above wireless communication system are provided. When the same antenna or radio frequency resource is applied to multiple frequency bands / carriers in a time-division manner by means of handover, resource measurement can be achieved, improving system performance.

[0032] Next, the measurement method, the configuration method for the handover mode, the communication node, and their technical effects in the handover mode are described.

[0033] Figure 2 is a schematic flowchart of a measurement method in a handover mode provided by an embodiment. As Figure 2 shown, the method provided in this embodiment is applicable to a first communication node (which can also be 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.

[0034] S210. When the first communication node operates on multiple aggregated resources, receive the handover mode configuration configured by the second communication node. The handover mode configuration is used to instruct the first communication node to perform signal transmission on the first resource during the first time period and perform signal transmission on the second resource during the second time period. The handover mode configuration includes at least the configuration of the handover period.

[0035] To increase the throughput of the wireless communication system, the second communication node can configure the first communication node to operate on multiple aggregated resources. The multiple resources can be aggregated in the CA manner or in the DC manner. One resource corresponds to a frequency bandwidth segment, and the frequency bandwidths corresponding to the respective resources can overlap or not overlap.

[0036] In one embodiment, the resource can be a cell or a carrier / band. That is, the first communication node operates on multiple cells aggregated in the CA manner or the DC manner, or operates on multiple bands aggregated in the CA manner or the DC manner.

[0037] In one embodiment, the duplex modes of different resources are the same, or the duplex modes of different resources are different. The duplex mode includes at least one of the following: Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), Supplementary DownLink (SDL), Supplementary UpLink (SUL), etc.

[0038] Exemplarily, the duplex mode of one resource (cell 1 or band 1) is FDD, and the duplex mode of another resource (cell 2 or band 2) is SDL; the duplex mode of one resource (cell 1 or band 1) is FDD, and the duplex mode of another resource (cell 2 or band 2) is FDD; the duplex mode of one resource (cell 1 or band 1) is TDD, and the duplex mode of another resource (cell 2 or band 2) is FDD; the duplex mode of one resource (cell 1 or band 1) is TDD, and the duplex mode of another resource (cell 2 or band 2) is SDL; the duplex mode of one resource (cell 1 or band 1) is TDD, and the duplex mode of another resource (cell 2 or band 2) is TDD.

[0039] Figure 3 is a schematic diagram of a handover mode configuration provided by an embodiment, as Figure 3As shown, the switching mode configuration instructs the first communication node to perform signal transmission on the first resource within the first time period T1 and on the second resource within the second time period T2. That is, the antenna or radio frequency resources of the first communication node are used on the first resource within T1 and on the second resource within T2. For example, the switching mode configuration may be a receive switching pattern. The switching mode configuration includes at least the configuration of the switching period. There is a guard period GP between the first resource and the second resource. The guard period GP may or may not be configured by explicit signaling, but is implicitly determined by indicators such as radio frequency switching or switch transition time. When GP is determined in an implicit manner, one or two GP durations may be included within the durations of T1 and T2. In this case, there is no need to additionally consider the GP length between the first resource and the second resource in the following solutions, and only the durations of T1 and T2 need to be considered. Exemplarily, in the embodiments of the present application, the case where GP is configured by explicit signaling is taken as an example, that is, the GP length needs to be additionally considered for description.

[0040] Since the resource can be a cell or a carrier / band. When the resource is a cell, the first cell is a PCell or a Primary secondary Cell (PSCell) or an SCell, and the second cell is an SCell; when the resource is a band, the first band is a band configured with a PCell or a PSCell or an SCell, and the second band is another band configured with an SCell. Among them, the other band configured with an SCell defined by the second band means that this band is different from the band configured with an SCell defined by the first band.

[0041] The signal transmission performed by the first communication node on the first resource is the reception of a downlink signal and / or the transmission of an uplink signal; the signal transmission performed by the first communication node on the second resource is the reception of a downlink signal and / or the transmission of an uplink signal.

[0042] Exemplarily, the signal transmission performed by the first communication node on the first resource is the reception of a downlink signal, and the signal transmission performed by the first communication node on the second resource is the reception of a downlink signal; or, the signal transmission performed by the first communication node on the first resource is the reception of a downlink signal and the transmission of an uplink signal, and the signal transmission performed by the first communication node on the second resource is the reception of a downlink signal; or, the signal transmission performed by the first communication node on the first resource is the transmission of an uplink signal, and the signal transmission performed by the first communication node on the second resource is the reception of a downlink signal.

[0043] S220. Measure the target resource according to the switching mode configuration.

[0044] Based on the handover mode configuration configured by the second communication node, the first communication node can perform measurements on the target resources. In one embodiment, the target resources can be the first resource, the second resource, or other resources other than the first resource and the second resource (such as neighbor cell resources, different frequency resources, etc.).

[0045] The following will respectively use different examples to detail the functions that the first communication node can achieve in the handover mode.

[0046] Example 1: When the first communication node performs signal transmission on the first resource within 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?

[0047] Specifically, in the case of meeting at least one of the following, the first communication node determines that the second resource is in an inactive state:

[0048] Within the first time period and the guard interval;

[0049] The first time period is greater than the first threshold, and within the first time period or within the first time period and the guard interval;

[0050] The first ratio is greater than the second threshold, and within the first time period or within the first time period and the guard interval; the first ratio is equal to the ratio of the duration of the first time period to the handover period, or the first ratio 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;

[0051] The second time period is less than or equal to the third threshold, and within the first time period or within the first time period and the guard interval;

[0052] The second ratio is less than or equal to the fourth threshold, and within the first time period or within the first time period and the guard interval; the second ratio is equal to the ratio of the duration of the second time period to the handover period, or the second ratio 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.

[0053] Exemplarily, assuming that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell, when the UE performs signal transmission on the PCell within T1, the UE can determine whether the SCell is in an inactive state or an active state through the following method.

[0054] Method 1-1) The UE believes that within T1 and GP, the SCell is in an inactive state; otherwise, the UE determines when the SCell is in an active state and when it is in an inactive state according to the legacy method.

[0055] 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 the active state and when it is in the 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 the inactive state within T1 or T1+GP.

[0056] Method 1-3) The UE determines the first ratio (i.e., the ratio of the duration of T1 to the switching periodicity; or the ratio of the duration of T1 to the sum of the durations of T1 and T2, i.e., T1 / (T1+T2)), and then compares the first ratio with the second threshold. When the first ratio is not greater than the second threshold, the UE determines when the SCell is in the active state and when it is in the inactive state according to the legacy method; when the first ratio is greater than the second threshold, the UE considers that the SCell is in the inactive state within T1 or T1+GP.

[0057] Method 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 the active state and when it is in the 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 the inactive state within T1 or T1+GP.

[0058] Method 1-5) The UE determines the second ratio (i.e., the ratio of the duration of T2 to the switching periodicity; or the ratio of the duration of T2 to the sum of the durations of T1 and T2, i.e., T2 / (T1+T2)), and then compares the second ratio with the fourth threshold. When the second ratio is greater than the fourth threshold, the UE determines when the SCell is in the active state and when it is in the inactive state according to the legacy method; when the second ratio is less than or equal to the fourth threshold, the UE considers that the SCell is in the inactive state within T1 or T1+GP.

[0059] 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.

[0060] Example 2: When the first communication node determines whether co-frequency measurement or inter-frequency measurement needs to be performed with the help of a gap, how to determine the active DL BWP.

[0061] Specifically, the active DL BWP on the first resource and / or the second resource is determined according to at least one of the following:

[0062] When the first communication node performs signal transmission on the first resource within the first time period, the active DL BWP on the second resource is determined according to the active DL BWP at the last moment within the previous second time period;

[0063] It is determined according to the active DL BWP configured by RRC signaling.

[0064] In one embodiment, the active DL BWP configured by RRC signaling is the first active DL BWP or the initial DL BWP.

[0065] In one embodiment, the RRC signaling configures the default active DL BWP as the 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 signaling for activating or deactivating the second resource for the last time; included in the RRC signaling for configuring handover-related parameters for the last time.

[0066] Exemplarily, assume that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell. When the UE determines whether the intra-frequency measurement or inter-frequency measurement on the SCell needs to be performed with the help of a gap within T1, or when the UE determines whether the intra-frequency measurement or inter-frequency measurement on the PCell needs to be performed with the help of a gap within T2, the active DL BWP is determined in the following manner.

[0067] Method 2-1) When the UE performs signal transmission on the PCell within T1, the UE determines the active DL BWP on the SCell according to the active DL BWP at the last moment within the previous T2. That is, the UE determines which BWP is the active DL BWP at the last moment within the previous T2, and then can use this BWP as the active DL BWP of the SCell within T1 to determine whether the layer 3 (L3) RS is wrapped by the active DL BWP in the frequency domain, so as to decide whether this L3 measurement needs to be performed with the help of a gap.

[0068] When the UE performs signal transmission on the SCell within T2, at this time the UE does not need to assume the active DL BWP on the SCell because it is actually being used and the active DL BWP can be directly obtained.

[0069] Method 2-2) The UE determines according to the active DL BWP configured by RRC signaling.

[0070] For example, the UE determines it according to the first active DL BWP configured by the existing RRC signaling. That is, it is assumed that the BWP configured by the first active DL BWP in the existing RRC signaling is the active DL BWP. This RRC signaling may be included in the most recent RRC reconfiguration message (RRC reconfiguration message).

[0071] For another example, the UE determines it according to the initial DL BWP configured by the existing RRC signaling. That is, it is assumed that the BWP configured by the initial active DL BWP in the existing RRC signaling is the active DL BWP.

[0072] For another example, the UE configures the default active DL BWP as the active DL BWP according to 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 signaling for activating or deactivating the SCell for the last time; included in the RRC signaling for configuring handover-related parameters for the last time.

[0073] After the UE determines which BWP the active DL BWP is and what the frequency domain resource range is based on the above methods, it can further determine whether co-frequency measurement or inter-frequency measurement needs to be performed with the help of a gap according to the active DL BWP.

[0074] Example 3: When the first communication node performs measurement on the first resource within the first time period T1, how does the first communication node determine whether to use the SSB-less SCell operation mode for the measurement of the second resource, that is, whether the first communication node needs to automatically switch to the SSB-less SCell operation mode.

[0075] Specifically, the first communication node uses the SSB-less SCell operation mode for the measurement of the second resource under at least one of the following conditions:

[0076] The first resource and the second resource are deployed at the same site;

[0077] The frequency domain interval between the frequency points of the first resource and the second resource or the frequency bands where they are located is less than a preset threshold;

[0078] The first communication node supports the SSB-less SCell capability for the frequency band combination where the first resource and the second resource are located;

[0079] The second communication node does not configure a measurement object (MO) based on synchronization signal and SSB measurement and / or Channel State Information-reference signal (CSI-RS) measurement on the second resource.

[0080] In one embodiment, when the first communication node performs measurement on the first resource within the first time period, at least one of the following is satisfied:

[0081] The first communication node determines whether to adopt the SSB-less SCell operation mode for the measurement of the second resource according to the explicit indication of the second communication node through dedicated RRC configuration signaling;

[0082] The first communication node determines whether to adopt the SSB-less SCell operation mode for the measurement of the second resource according to the implicit indication of the second communication node through other RRC configuration signaling.

[0083] Exemplarily, assume that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell. When the UE performs measurement on the PCell within T1, the UE can determine whether to adopt the SSB-less SCell operation mode for the measurement of the SCell in the following manner.

[0084] Method 3-1) When at least one of the following conditions is satisfied, the UE adopts the SSB-less SCell operation mode:

[0085] Condition 1: The PCell and the SCell are deployed at the same site.

[0086] Condition 2: The frequency domain interval between the frequency points of the PCell and the SCell or the frequency bands where they are located is less than a preset threshold.

[0087] When Condition 1 or 2 is satisfied, the UE can assume that the RRC measurement result on the PCell frequency is reused for the SCell frequency, thereby eliminating the additional gap or interruption overhead brought by the UE for performing the SCell frequency measurement within T1. That is, the UE adopts the SSB-less SCell operation mode.

[0088] Condition 3: The UE reports the capability of supporting SSB-less SCell for the frequency band combination of the PCell and the SCell.

[0089] Condition 4: The base station does not configure the SSB configuration for L3 measurement or mobility measurement for the SCell (for example, it can be related configurations such as the SSB-Based Measurement Timing Configuration (SMTC) in the MO).

[0090] Condition 5: The base station does not configure the CSI-RS configuration for L3 measurement or mobility measurement for the SCell (for example, it can be the CSI-RS related configuration in the MO).

[0091] Method 3-2) Explicitly or implicitly indicate through the RRC configuration signaling whether the UE enables the SSB-less SCell operation for the SCell within T1, that is, does not perform SSB based L3 measurement on the SCell.

[0092] Explicit indication means introducing dedicated RRC signaling to indicate whether the UE enables the SSB-less SCell operation.

[0093] Implicit indication means indicating whether the UE enables the SSB-less SCell operation through other RRC signaling.

[0094] Example 4: When the first communication node performs measurement on the second resource within the second time period T2, how does the first communication node determine whether to adopt the SSB-less SCell operation mode for the measurement of the second resource, that is, whether the first communication node needs to automatically switch to the SSB-less SCell operation mode.

[0095] Specifically, when the first communication node performs measurement on the second resource within the second time period, at least one of the following is satisfied:

[0096] When the second communication node configures the measurement object MO based on SSB measurement on the second resource, the first communication node does not adopt the SSB-less SCell operation mode for the measurement of the second resource;

[0097] When the second communication node configures the MO based on SSB measurement on the second resource, the first communication node determines whether to adopt the SSB-less SCell operation mode for the measurement of the second resource according to the explicit indication of the second communication node through the RRC signaling;

[0098] When the second communication node configures the MO based on SSB measurement on the second resource, the first communication node determines whether to adopt the SSB-less SCell operation mode for the measurement of the second resource according to the SSB configuration and the handover mode configuration.

[0099] Among them, when the second communication node configures 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 in the handover mode, the first communication node determines that the measurement of the second resource does not adopt the SSB-less SCell operation mode;

[0100] When the second communication node configures 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 does not fall within the second time period configured in the handover mode, the first communication node determines that the measurement of the second resource adopts the SSB-less SCell operation mode;

[0101] When the second communication node configures an MO based on SSB measurement on the second resource, if some of the SSB occasions determined by the first communication node according to the SSB configuration fall within the second time period configured in the handover mode, and some other SSB occasions fall outside the second time period or within the first time period configured in the handover mode, the first communication node determines that the measurement of the second resource adopts the SSB-less SCell operation mode.

[0102] Exemplarily, assume that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell. When the UE measures on the SCell within T2, the UE can determine whether to adopt the SSB-less SCell operation mode for the measurement of the SCell in the following ways.

[0103] Method 4-1): As long as the base station configures an MO based on SSB measurement on the SCell, the UE always performs L3 measurement based on SSB on the SCell and does not enable the SSB-less SCell operation mode.

[0104] Method 4-2): Even if the base station configures an MO based on SSB measurement on the SCell, whether the UE performs L3 measurement based on SSB on the SCell is explicitly indicated by the base station to the UE through RRC signaling. Specifically, this RRC signaling can be valid for both T1 and T2, or only valid for T2.

[0105] Method 4-3): If the base station configures an SSB on the SCell, it is jointly determined whether to perform L3 measurement based on SSB on the SCell according to the SSB configuration and the handover mode configuration. Specifically, at least one of the following is adopted:

[0106] If the SSB occasion determined according to the SSB configuration (specifically, the SSB configuration period and / or the SSB time domain offset) falls within T2 configured in the switching pattern, then perform SSB-based L3 measurement on the SCell.

[0107] If the SSB occasion determined according to the SSB configuration (specifically, the SSB configuration period and / or the SSB time domain offset) does not fall within T2 configured in the switching pattern, then do not perform SSB-based L3 measurement on the SCell, and reuse the L3 measurement result of the PCell as the L3 measurement result of the SCell.

[0108] If some of the SSB occasions determined according to the SSB configuration (specifically, the SSB configuration period and / or the SSB time domain offset) fall within T2 configured in the switching pattern, and the other part of the SSB occasions fall outside T2 or within T1 configured in the switching pattern, then do not perform SSB-based L3 measurement on the SCell, and reuse the L3 measurement result of the PCell as the L3 measurement result of the SCell.

[0109] In the above Examples 3 and 4, when the first communication node measures the second resource in the SSB-less SCell operation mode, the first communication node does not perform the SSB-based layer 3 measurement (L3 measurement) on the second resource, and reuses the SSB-based L3 measurement result of the first resource as the SSB-based L3 measurement result of the second resource.

[0110] Example 5: When the first communication node measures the first resource within the first time period T1, in order to reduce the interruption caused by the UE performing the L3 measurement on the second resource, the L3 measurement on the second resource is performed in at least one of the following ways:

[0111] Perform according to the capability indication information; the capability indication information is used to indicate whether the first communication node can perform gapless (without gap) or short-gap (with short gap) L3 measurement on the second resource when transmitting signals on the first resource within the first time period.

[0112] Relax the measurement of the L3 measurement on the second resource.

[0113] In one embodiment, the measurement period corresponding to the relaxation measurement is at least one of the following: Discontinuous Reception Cycle (DRX cycle), handover cycle, and the product of the inactivity measurement period configured by the second communication node for the second resource and the relaxation factor.

[0114] In one embodiment, the second resource is in an active state or an inactive state; when the second resource is in an active state, the value of 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.

[0115] Exemplarily, assume that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell. When the UE performs measurements on the PCell within T1, for the L3 measurement of the activated SCell, in order to reduce the interruption caused by the UE performing the L3 measurement on the SCell, at least one of the following methods is adopted:

[0116] Method 5-1) introduces a new UE capability, which indicates whether the UE can still perform L3 measurements on the L3 RS of the activated state SCell without a gap or with a short gap when switching to the PCell. If the UE indicates to the base station that it supports this capability for a specific combination of the PCell and SCell bands or a specific band, it means that the UE can perform L3 measurements on the activated state SCell without a gap or with a short gap within T1 when switching to the PCell. If the UE does not indicate this capability or indicates that it does not support this capability for a specific combination of the PCell and SCell bands or a specific band, it means that the UE can only perform L3 measurements with a gap on the activated state SCell in the specific band combination or specific band within T1.

[0117] Method 5-2) relaxes the L3 measurement for the SCell within T1, that is, the UE performs the L3 measurement with a larger measurement period. The larger measurement period refers to a period larger than the SMTC period or the CSI-RS period configured in the MO. Specifically, at least one of the following is adopted:

[0118] If DRX cycle is configured, the DRX cycle is used as the measurement period for performing L3 measurements on the activated SCell within T1. Specifically, if L3 measurements based on SSB are configured, the UE selects one occasion from all SSB occasions that fall within the DRX ON time period to perform L3 measurements on the activated SCell. If L3 measurements based on CSI-RS are configured, the UE selects one occasion from all CSI-RS occasions that fall within the DRX ON time period to perform L3 measurements on the activated SCell.

[0119] The switching pattern periodicity is used as the measurement period for performing L3 measurements on the activated SCell within T1. Specifically, if L3 measurements based on SSB are configured, within each switching pattern periodicity, the UE selects one occasion from all SSB occasions that fall within T1 to perform L3 measurements on the activated SCell. If L3 measurements based on CSI-RS are configured, within each switching pattern periodicity, the UE selects one occasion from all CSI-RS occasions that fall within T1 to perform L3 measurements on the activated SCell.

[0120] The UE uses the deactivated SCell measurement cycle measCycleSCell configured by the base station for this SCell to perform L3 measurements on the activated SCell within T1. Specifically, if L3 measurements based on SSB are configured, within each measCycleSCell duration, the UE selects one occasion from all SSB occasions that fall within T1 to perform L3 measurements on the activated SCell. If L3 measurements based on CSI-RS are configured, within each measCycleSCell duration, the UE selects one occasion from all CSI-RS occasions that fall within T1 to perform L3 measurements on the activated SCell.

[0121] Exemplarily, assume that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell. When the UE performs measurements on the PCell within T1, for the L3 measurement of the deactivated SCell, in order to reduce the interruption caused by the UE performing the L3 measurement on the SCell, at least one of the following methods is adopted:

[0122] Method 5-3) introduces a new UE capability that indicates whether the UE can still perform L3 measurements on the L3 RS of the deactivated SCell without a gap or with a short gap when switching to the PCell. If the UE indicates to the base station that it supports this capability for a specific PCell, SCell band combination, or specific band, it means that the UE can perform L3 measurements on the deactivated SCell without a gap or with a short gap within T1 when switching 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 specific band, it means that the UE can only perform L3 measurements with a gap on the deactivated SCell on the specific band combination or specific band within T1.

[0123] Method 5-4) relaxes the L3 measurement for the deactivated SCell within T1, that is, the UE performs L3 measurements with a larger measurement period. A larger measurement period means larger than the SMTC period or CSI-RS period configured in the MO. Specifically, at least one of the following is adopted:

[0124] If the DRX cycle is configured, the DRX cycle is used as the measurement period for performing L3 measurements on the deactivated SCell within T1. Specifically, if L3 measurements based on SSB are configured, the UE selects one occasion from all SSB occasions that fall within the DRX ON time period to perform L3 measurements on the deactivated SCell. If L3 measurements based on CSI-RS are configured, the UE selects one occasion from all CSI-RS occasions that fall within the DRX ON time period to perform L3 measurements on the deactivated SCell.

[0125] The switching pattern periodicity is used as the measurement period for performing L3 measurements on the deactivated state SCell within T1. Specifically, if SSB-based L3 measurements are configured, the UE selects one occasion from all SSB occasions falling within T1 to perform L3 measurements on the deactivated state SCell within each switching pattern periodicity. If CSI-RS-based L3 measurements are configured, the UE selects one occasion from all CSI-RS occasions falling within T1 to perform L3 measurements on the deactivated state SCell within each switching pattern periodicity.

[0126] The UE uses the deactivated SCell measurement period measCycleSCell configured by the base station for this SCell, and then introduces a relaxation factor f. The UE uses f * measCycleSCell as the measurement period to perform L3 measurements on this deactivated state SCell within T1. Here, f is a constant greater than or equal to 1, which is predefined by the system or semi-statically configured by the base station. Specifically, if SSB-based L3 measurements are configured, the UE selects one occasion from all SSB occasions falling within T1 to perform L3 measurements on this deactivated state SCell within each f * measCycleSCell duration. If CSI-RS-based L3 measurements are configured, the UE selects one occasion from all CSI-RS occasions falling within T1 to perform L3 measurements on this deactivated state SCell within each f * measCycleSCell duration.

[0127] Example 6: For a multi-carrier application scenario with a configured handover mode configuration, how the first communication node performs the second resource activation process. Specifically, at least one of the following is satisfied:

[0128] The first communication node only performs SSB measurements or tracking reference signal (TRS) measurements required for the second resource activation process within the second time period;

[0129] The first communication node can perform SSB measurements or TRS measurements required for the second resource activation process within both the first time period and the second time period.

[0130] In one embodiment, when the first communication node performs the SSB measurement or the TRS measurement required for the second resource activation process only within the second time period, the baseband resources applied to the second resource during the measurement process are preferentially allocated to this measurement, and the carrier-specific scaling factor (CSSF) corresponding to this measurement takes a value of 1;

[0131] When the first communication node can perform the SSB measurement or the TRS measurement required for the second resource activation process within both the first time period and the second time period, the baseband resources applied to the second resource during the measurement process are preferentially allocated to this measurement, and the CSSF corresponding to this measurement takes a value of 1.

[0132] Exemplarily, assume that the first communication node is a UE, the first resource is a PCell, and the second resource is an SCell. When the UE performs SCell activation, it needs to perform one or more measurements based on the SSB or TRS on the SCell, and at least one of the following methods is adopted:

[0133] Method 6-1) The UE only performs the SSB measurement or the TRS measurement required for the SCell activation process within T2. When the SSB period or the TRS period is large, the UE may not be able to complete the entire SCell activation process within one T2. Then the UE performs multiple SSB or TRS measurements discontinuously within multiple T2s of the switching pattern periodicity to complete the SCell activation process. For the SCell SSB occasion or the SCell TRS occasion that falls within the period T1, the UE does not perform the measurement required for SCell activation. The entire SCell activation process takes a long time in this method, but no gap is required.

[0134] Method 6-2) The UE can perform the SSB measurement or the TRS measurement required for the SCell activation process within both the time period T2 and T1. When the SSB period or the TRS period is large, the UE may not be able to complete the entire SCell activation process within one T1 + T2. Then the UE performs multiple SSB or TRS measurements continuously or discontinuously within multiple T1 + T2s of the switching pattern periodicity to complete the SCell activation process. The SCell SSB measurement or the SCell TRS measurement performed by the UE within T2 does not require a gap. The SCell SSB measurement or the SCell TRS measurement performed by the UE within T1 requires a gap.

[0135] Whether it is the above method 6-1) or method 6-2), when the UE performs SCell SSB measurement or SCell TRS measurement without the need for a gap within T2, if the UE has other co-frequency or cross-frequency measurements without the need for a gap to perform, then in order to ensure that the delay of the SCell activation process is as small as possible, the baseband resources (searcher) available for the SCell are preferentially allocated to the SCell SSB measurement or SCell TRS measurement in the SCell activation process.

[0136] Example 7: After the handover mode configuration is enabled, the first communication node uses one or more baseband resources to perform primary component carrier (PCC) frequency point measurement within the first time period and uses one or more baseband resources to perform secondary component carrier (SCC) frequency point measurement within the second time period.

[0137] Specifically, when the first communication node uses multiple baseband resources to perform SCC frequency point measurement within the second time period, at least one of the following allocation methods is adopted:

[0138] At least one baseband resource is used for SSB-based measurement on the SCC frequency point, and another baseband resource is used for CSI-RS-based measurement on the SCC frequency point and other inter-frequency measurement objects (inter-frequency MO) without a gap, and interoperability measurement objects (inter-RAT MO) between different radio access technologies;

[0139] At least one baseband resource is used for SCell measurement on the SCC frequency point, and another baseband resource is used for neighbor cell measurement on the SCC frequency point and other inter-frequency MO and inter-RAT MO measurements without a gap;

[0140] At least one baseband resource is used for SCC frequency point measurement with neighbor cell measurement requirements on the SCC frequency point, and another baseband resource is used for other one or more SCC frequency point measurements without neighbor cell measurement requirements on the SCC frequency point and other inter-frequency MO and inter-RAT MO measurements without a gap;

[0141] At least one baseband resource is used for high-priority SCC frequency point measurement, and another baseband resource is used for the remaining SCC frequency point measurement and other inter-frequency MO and inter-RAT MO measurements without a gap.

[0142] Exemplarily, when the Switching pattern is enabled, the UE receives alignment for the PCell within T1 and receives alignment for the SCell within T2, which will affect the traditional CSSF calculation and how the baseband resource searcher for the UE to perform measurements is allocated.

[0143] For traditional UEs, it is generally considered that the UE has two or three searchers for performing gapless Radio Resource Management (RRM) measurements. The general principle for allocating searchers is as follows: In CA, one searcher is dedicated to PCC measurement, and the other searcher is shared for SCC, inter-frequency gapless measurement, and inter-RAT gapless measurement. In DC, one searcher is dedicated to PCC measurement, and the other searcher is shared for PSCC, SCC, inter-frequency gapless measurement, and inter-RAT gapless measurement.

[0144] For the gapful RRM measurement of traditional UEs, the UE can only perform gapful RRM measurement on one frequency point or MO at the same time.

[0145] Then, after the switching pattern is enabled, within T1, the UE is very likely unable to perform gapless measurements on the SCC or other inter-frequency MOs, inter-RAT MOs. Then the UE can use two or three searchers for the measurement of the PCC frequency point. For example, one searcher is used for SSB-based measurement on the PCC frequency point, and the other searcher is used for CSI-RS-based measurement on the PCC frequency point. Therefore, a new calculation method needs to be introduced for the CSSF factor.

[0146] Correspondingly, within T2, the UE can use two or three searchers for the measurement of the SCC frequency point, and can adopt at least one of the following allocation methods:

[0147] Method 7-1): Use one searcher for SSB-based measurement on the SCC frequency point, and the other searcher for CSI-RS-based measurement on the SCC frequency point and other gapless inter-frequency MOs, inter-RAT MOs measurement.

[0148] Method 7-2): Use one searcher for SCell measurement on the SCC frequency band, and use the other searcher for neighbor cell measurement on the SCC frequency band and other inter-frequency MO and inter-RAT MO measurements without gap.

[0149] Method 7-3): Use one searcher for SCC 1 frequency band measurement with neighbor cell measurement requirements on the SCC frequency band, and use the other searcher for measurement of one or more other SCC frequency bands without neighbor cell measurement requirements on the SCC frequency band and other inter-frequency MO and inter-RAT MO measurements without gap.

[0150] Method 7-4): Use one searcher for high-priority SCC frequency band measurement, and use the other searcher for measurement of all other SCC frequency bands and other inter-frequency MO and inter-RAT MO measurements without gap.

[0151] Method 7-5): The allocation principle of the third and more searchers can be the same as that of the first searcher.

[0152] Figure 4 It is a schematic flowchart of a configuration method for a handover mode provided by an embodiment. As Figure 4 shown, the method provided by this embodiment is applicable to a second communication node (which can also be 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.

[0153] S410. When the first communication node is operating on a plurality of aggregated resources, configure a handover mode configuration for the first communication node. The handover mode configuration is used to instruct the first communication node to perform signal transmission on the first resource during the first time period and perform signal transmission on the second resource during the second time period. The handover mode configuration at least includes the configuration of the handover period.

[0154] To increase the throughput of the wireless communication system, the second communication node can configure the first communication node to operate on a plurality of aggregated resources. The plurality of resources can be aggregated by means of CA or by means of DC. One resource corresponds to a frequency bandwidth segment, and the frequency bandwidths corresponding to the respective resources can overlap or not overlap.

[0155] In one embodiment, the resource can be a cell or a carrier / band. That is, the first communication node operates on multiple cells aggregated in a CA or DC manner, or operates on multiple bands aggregated in a CA or DC manner.

[0156] In one embodiment, the duplexing modes of different resources are the same, or the duplexing modes of different resources are different. The duplexing mode includes at least one of the following: FDD, TDD, SDL, SUL, etc.

[0157] Exemplarily, the duplexing mode of one resource (Cell 1 or Band 1) is FDD, and the duplexing mode of another resource (Cell 2 or Band 2) is SDL; the duplexing mode of one resource (Cell 1 or Band 1) is FDD, and the duplexing mode of another resource (Cell 2 or Band 2) is FDD; the duplexing mode of one resource (Cell 1 or Band 1) is TDD, and the duplexing mode of another resource (Cell 2 or Band 2) is FDD; the duplexing mode of one resource (Cell 1 or Band 1) is TDD, and the duplexing mode of another resource (Cell 2 or Band 2) is SDL; the duplexing mode of one resource (Cell 1 or Band 1) is TDD, and the duplexing mode of another resource (Cell 2 or Band 2) is TDD.

[0158] The handover mode configuration instructs the first communication node to perform signal transmission on a first resource within a first time period T1 and perform signal transmission on a second resource within a second time period T2. That is, the antenna or radio frequency resources of the first communication node are used on the first resource within T1 and used on the second resource within T2. For example, the handover mode configuration can be a receive handover pattern. The handover mode configuration at least includes the configuration of the handover period. There is a guard period GP between the first resource and the second resource. The guard period GP may be configured by explicit signaling, or may not be configured by explicit signaling, but is implicitly determined by indicators such as radio frequency handover or switch conversion time.

[0159] Since the resource can be a cell or a carrier / band. When the resource is a cell, the first cell is a PCell or a primary PSCell or an SCell, and the second cell is an SCell; when the resource is a band, the first band is a band configured with a PCell or a PSCell or an SCell, and the second band is another band configured with an SCell. Among them, the other band configured with an SCell defined by the second band refers to the band that is different from the band configured with an SCell defined by the first band.

[0160] In one embodiment, the second communication node configures at least one of the following for the first communication node;

[0161] Configure the active DL BWP via RRC signaling. In one implementation, the active DL BWP configured by RRC signaling is the first active DL BWP or the initial DL BWP. In another implementation, the RRC signaling configures the default active DL BWP as the 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 signaling for activating or deactivating the second resource for the most recent time; included in the RRC signaling for configuring handover-related parameters for the most recent time.

[0162] Explicitly indicate via dedicated RRC configuration signaling whether the measurement of the second resource by the first communication node adopts the SSB-less SCell operation mode without transmitting synchronization signals and physical broadcast channel blocks;

[0163] Implicitly indicate via other RRC configuration signaling whether the measurement of the second resource by the first communication node adopts the SSB-less SCell operation mode.

[0164] In one embodiment, the second communication node may also semi-statically configure a first threshold, a second threshold, a third threshold, and a fourth threshold for the first communication node via RRC signaling. The specific uses of the first threshold to the fourth threshold may refer to the description of the above embodiment. For the sake of brevity, it will not be elaborated here.

[0165] In one embodiment, the second communication node may also configure an inactive state measurement period for the second resource.

[0166] In one embodiment, the second communication node configures an MO based on SSB measurement and / or CSI-RS measurement on the second resource.

[0167] Figure 5 It is a schematic structural diagram of a measurement device in a handover mode provided by an embodiment. The device may be configured in the first communication node, such as Figure 5 shown. The device includes: a first communication module 501 and a measurement module 502.

[0168] The first communication module 501 is configured to receive the handover mode configuration configured by the second communication node when the first communication node operates on a plurality of aggregated resources. The handover mode configuration is used to indicate that the first communication node performs signal transmission on the first resource in the first time period and performs signal transmission on the second resource in the second time period. The handover mode configuration includes at least the configuration of the handover period;

[0169] The measurement module 502 is configured to measure the target resource according to the handover mode configuration.

[0170] The measurement device in the handover mode provided in this embodiment is for implementing Figure 2 the measurement method in the handover mode of the embodiment shown. The implementation principle and technical effect of the measurement device in the handover mode provided in this embodiment are similar to those of the above embodiment, and will not be elaborated here.

[0171] In one embodiment, the duplex modes of different resources are the same, or the duplex modes of different resources are different;

[0172] The duplex mode includes at least one of the following: Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), Supplementary Downlink (SDL), and Supplementary Uplink (SUL).

[0173] In one embodiment, the signal transmission performed by the first communication node on the first resource is the reception of a downlink signal and / or the transmission of an uplink signal;

[0174] The signal transmission performed by the first communication node on the second resource is the reception of a downlink signal and / or the transmission of an uplink signal.

[0175] In one embodiment, the resource is a cell or a frequency band.

[0176] In one embodiment, when the resource is a cell, the first cell is a Primary Cell (PCell) or a Primary Secondary Cell (PSCell) or a Secondary Cell (SCell), and the second cell is an SCell;

[0177] When the resource is a frequency band, the first frequency band is a frequency band configured with a PCell or a PSCell or an SCell, and the second frequency band is another frequency band configured with an SCell.

[0178] In one embodiment, when the first communication node performs signal transmission on the first resource within the first time period, the second resource is in an inactive state when at least one of the following conditions is met:

[0179] Within the first time period and the guard interval;

[0180] The first time period is greater than the first threshold, and within the first time period or within the first time period and the guard interval;

[0181] The first ratio is greater than the second threshold, and within the first time period or within the first time period and the guard interval; The first ratio is equal to the ratio of the duration of the first time period to the handover period, or the first ratio 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;

[0182] The second time period is less than or equal to the third threshold, and within the first time period or within the first time period and the guard interval;

[0183] The second ratio is less than or equal to the fourth threshold, and within the first time period or within the first time period and the guard interval; the second ratio is equal to the ratio of the duration of the second time period to the handover period, or the second ratio 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.

[0184] 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.

[0185] In one embodiment, the active downlink bandwidth part (active DL BWP) on the first resource and / or the second resource is determined according to at least one of the following:

[0186] When the first communication node performs signal transmission on the first resource within the first time period, the active DL BWP on the second resource is determined according to the active DL BWP at the last moment within the previous second time period;

[0187] Determined according to the active DL BWP configured by RRC signaling.

[0188] In one embodiment, the active DL BWP configured by RRC signaling is the first active downlink bandwidth part (first active DL BWP), or the initial downlink bandwidth part (initial DL BWP).

[0189] In one embodiment, the default active downlink bandwidth part (default active DL BWP) configured by RRC signaling is the active DL BWP, and the RRC signaling indicates it through at least one of the following:

[0190] Contained in the most recent RRC reconfiguration message;

[0191] Contained in the signaling for activating or deactivating the second resource for the most recent time;

[0192] Contained in the RRC signaling for configuring handover-related parameters for the most recent time.

[0193] In one embodiment, when the first communication node performs measurements on the first resource within the first time period, the first communication node uses the SSB-less SCell operation mode of not transmitting synchronization signals and physical broadcast channel blocks for the measurements of the second resource when at least one of the following is satisfied:

[0194] The first resource and the second resource are deployed at the same site;

[0195] The frequency domain interval between the frequency points of the first resource and the second resource or the frequency bands where they are located is less than a preset threshold;

[0196] The first communication node supports the SSB-less SCell capability for the frequency band combination where the first resource and the second resource are located;

[0197] The second communication node does not configure a measurement object MO based on synchronization signal and physical broadcast channel block SSB measurement and / or channel state information reference signal CSI-RS measurement on the second resource.

[0198] In one embodiment, when the first communication node performs measurements on the first resource within the first time period, at least one of the following is satisfied:

[0200] The first communication node determines whether to adopt the SSB-less SCell operation mode for the measurement of the second resource according to the implicit indication of the second communication node through other RRC configuration signaling.

[0201] In one embodiment, when the first communication node performs measurements on the second resource within the second time period, at least one of the following is satisfied:

[0202] In the case where the second communication node configures a measurement object MO based on SSB measurement on the second resource, the first communication node does not adopt the SSB-less SCell operation mode for the measurement of the second resource;

[0204] In the case where the second communication node configures a measurement object MO based on SSB measurement on the second resource, the first communication node determines whether to adopt the SSB-less SCell operation mode for the measurement of the second resource according to the SSB configuration and the handover mode configuration.

[0205] In one embodiment, in the case where the second communication node configures a measurement object 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 of the handover mode configuration, the first communication node determines that the SSB-less SCell operation mode is not adopted for the measurement of the second resource;

[0206] When the second communication node configures 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 does not fall within the second time period configured in the handover mode, the first communication node determines to use the SSB-less SCell operation mode for the measurement of the second resource;

[0207] When the second communication node configures an MO based on SSB measurement on the second resource, if some of the SSB occasions determined by the first communication node according to the SSB configuration fall within the second time period configured in the handover mode and the other part of the SSB occasions fall outside the second time period or within the first time period configured in the handover mode, the first communication node determines to use the SSB-less SCell operation mode for the measurement of the second resource.

[0208] In one embodiment, when the first communication node uses the SSB-less SCell operation mode for the measurement of the second resource, the first communication node does not perform the SSB-based layer 3 measurement (L3 measurement) for the second resource, and multiplexes the SSB-based L3 measurement result for the first resource as the SSB-based L3 measurement result for the second resource.
