[0181] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0182] In some embodiments, the first network device 102 may include at least one of an access network device and a core network device, and the second network device 103 may include at least one of an access network device and a core network device.

[0183] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0184] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0185] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0186] In some embodiments, a core network device may be a single device comprising one or more network elements, or may be a plurality of devices or a group of devices, each comprising all or part of one or more network elements. A network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0187] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0188] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG. 1 , or a part of the main body thereof, but are not limited thereto.

[0189] The entities shown in Figure 1 are examples. The communication system may include all or part of the entities in Figure 1, and may also include other entities outside of Figure 1. The number and form of the entities are arbitrary. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0190] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0191] In the embodiments of the present disclosure, in a carrier aggregation (CA) or DC scenario, the first network device 102 and the second network device 103 may correspond to two nodes in a communication system. For example, in a DC scenario, the first network device 102 corresponds to a master node (MN), and the second network device 103 corresponds to a secondary node (SN).

[0192] In the disclosed embodiments, the MO configured on a network device, such as first network device 102, corresponds to a neighboring cell signal or other carrier signal to be measured. Due to manufacturing cost and shape factors, terminal 101 operates at the same frequency at the same time. Terminal 101 can measure the MO centered around that frequency at that time. For example, terminal 101 can easily measure neighboring cell signals on the same frequency as the current operating frequency while simultaneously receiving and sending data on the serving cell.

[0193] In the embodiment of the present disclosure, when the terminal 101 performs neighboring cell measurements of different frequencies, such as inter-frequency neighboring cells or other systems, such as other wireless networks with 5G NR frequencies, it is necessary to suspend communication with the serving cell, including suspending data reception RX or transmission TX with the serving cell, and it is necessary to adjust the radio frequency (RF) module to configure the frequency to perform measurements of the neighboring cells, and then resume connection with the serving cell after a period of time. The time interval during which the terminal 101 suspends communication with the serving cell to measure inter-frequency neighboring cells or other wireless neighboring cells is called MG.

[0194] In the disclosed embodiments, a network device, such as first network device 102, may configure multiple MOs for terminal 101. Multiple MOs may require MG-based measurements, and multiple MOs may compete for the same set of MGs. In this case, terminal 101 needs to determine the scaling factor for each MO to determine the corresponding measurement requirements, such as the measurement interval in the time domain.

[0195] In the embodiment of the present disclosure, there are two types of MGs configured in a network device such as the first network device 102:

[0196] One is the per-UE measurement gap, where the UE performs all measurements that require the measurement gap based on the MG.

[0197] The other is a measurement gap based on the frequency range (per-FR measurement gap), and the MG is divided into per-FR1 MG and per-FR2 MG. If the target frequency and the serving cell frequency are in the same FR, the terminal 101 performs MG-based measurement based on the FR MG configuration. The first network device 102 can configure per-FR1 MG and / or per-FR2 MG based on the capability information (independentGapConfig) reported by the terminal 101, where the FR1-based system is such as evolved universal terrestrial radio access (E-UTRA), universal terrestrial radio frequency division duplex (UTRA-FDD) and NR; the FR2-based system is such as NR. It can be understood that the capability information indicates that the terminal 101 supports the ability of independent radio frequency links to perform independent measurements of FR1 and FR2 respectively.

[0198] In the embodiment of the present disclosure, the measurement interval configuration in the DC scenario includes the following two situations:

[0199] If per-UE MGs are configured, the second network device 103 notifies the first network device 102 of the list of FR1 and FR2 measurement frequency bands configured by the second network device 103. The first network device 102 determines the measurement gap pattern (MG pattern) and gap sharing configuration. It is understood that the gap sharing configuration is used to handle measurement conflicts in scenarios where different MOs compete for the same set of MGs.

[0200] If per-FR MG is configured, the measurement interval configuration varies depending on the communication system. For example:

[0201] In Evolved Universal Terrestrial Radio Access Network and NR Dual Connectivity (E-UTRAN New Radio Dual Connectivity, EN-DC) or EN-DC (NGEN-DC) under the 5G core network, the second network device 103 will inform the first network device 102: the FR1 measurement frequency band list configured by the second network device 103, and the first network device 102 (eNB) will determine the FR1 interval pattern and interval sharing configuration; or, the first network device 102 will inform the second network device 103: the FR2 measurement frequency band list configured by the first network device 102, and the second network device 103 (en-gNB) will determine the FR2 interval pattern and interval sharing configuration and send them to the terminal 101.

[0202] In NR and 4G radio access network dual connectivity (NR eNB Dual Connection, NE-DC), the first network device 102 notifies the second network device 103 of the per-UE or per-FR1 MG pattern, and the second network device 103 can provide an interval request to the first network device 102 without carrying a frequency band list; in NR and NR dual connectivity (NR Dual Connection, NR-DC), the first network device 102 notifies the second network device 103 of the per-UE, per-FR1 or per-FR2 MG pattern, and the second network device 103 can inform the first network device 102: the FR1 and FR2 measurement frequency band lists configured by the second network device 103. In this case, the first network device 102 (gNB) determines the MG pattern and interval sharing configuration for FR1 and FR2.

[0203] In the disclosed embodiment, MGs can be of three types: concurrent measurement gaps, pre-configured measurement gaps (Pre-MGs), and network controlled small measurement gaps (NCSGs). Pre-MGs are suitable for standalone (SA) networking. Furthermore, in DC scenarios, since most MGs are configured by the first network device 102, the requirements of MGs in the frequency band under the node of the second network device 103 cannot be promptly known to the first network device 102.

[0204] Figure 2a is an interactive diagram of an information interaction method according to an embodiment of the present disclosure. As shown in Figure 2a, the present disclosure embodiment relates to an information interaction method, which includes:

[0205] In step S2101 , the first network device 102 sends third information to the second network device 103 .

[0206] In some embodiments, the first network device 102 corresponds to a MN, and the second network device 103 corresponds to a SN.

[0207] In some embodiments, the third information is used to indicate that the first network device 102 is to configure a Pre-MG.

[0208] In some embodiments, the third information may be indication information.

[0209] In some embodiments, the third information may be transmitted by configuration information such as a CG-ConfigInfo message or other messages.

[0210] In some embodiments, the first network device 102 sends the third information to the second network device 103 through an inter-node interface such as an Xn or X1 interface.

[0211] Optionally, the first network device 102 notifies the second network device 103 by sending third information: the measurement configuration of the first network device 102 includes Pre-MG configuration, that is, the first network device 102 will perform Pre-MG configuration.

[0212] In some embodiments, the second network device 103 receives the third information.

[0213] In step S2102 , the second network device 103 sends first information to the first network device 102 .

[0214] In some embodiments, the first information is used to indicate configuration requirement information of the Pre-MG.

[0215] In some embodiments, the first information may be indication information.

[0216] In some embodiments, the first information may be transmitted by configuration information such as a CG-Config message or other messages.

[0217] In some embodiments, the configuration requirement information includes at least one of the following:

[0218] Whether the second network device 103 requests to configure a Pre-MG;

[0219] The second network device 103 expects the purpose of the Pre-MG.

[0220] Alternatively, one bit may be used to indicate whether Pre-MG configuration is requested. For example, if the bit value is 1, it indicates that the second network device 103 requests Pre-MG configuration; if the bit value is 0, it indicates that the second network device 103 does not request Pre-MG configuration.

[0221] Alternatively, whether to request Pre-MG configuration can be indicated by enumeration. For example, if the enumeration value is true, it indicates that the second network device 103 requests Pre-MG configuration; if the enumeration value is false or the parameter is not configured, it indicates that the second network device 103 does not request Pre-MG configuration.

[0222] Optionally, the purpose of the Pre-MG may also be recorded as a gap purpose or a measurement purpose.

[0223] Optionally, according to different purposes of the Pre-MG, the Pre-MG can be divided into: pre-configured per-UE MG and pre-configured per-FR MG.

[0224] Optionally, the pre-configured per-FR MG can be further divided into a pre-configured per-FR1 MG or a pre-configured per-FR2 MG.

[0225] In some embodiments, the second network device 103 may send the first information to the first network device 102 through an inter-node interface such as an Xn or X1 interface.

[0226] Optionally, the second network device 103 notifies the first network device 102 whether the second network device 103 itself requests to configure a Pre-MG by sending the first information. The second network device 103 may also notify the first network device 102 of the Pre-MG purposes supported by the second network device 103, that is, the supported Pre-MGs.

[0227] In some embodiments, the first network device 102 receives the first information.

[0228] Step S2103: The first network device 102 determines second information according to the first information.

[0229] In some embodiments, the second information includes a Pre-MG pattern and / or purpose.

[0230] Optionally, the pattern of the Pre-MG may include at least one of the following: a start offset of the Pre-MG, a duration of the Pre-MG, and a repetition period of the Pre-MG.

[0231] Optionally, the purpose of the Pre-MG is used to indicate whether the Pre-MG is a pre-configured per-UE MG, a pre-configured per-FR1 MG, or a pre-configured per-FR2 MG.

[0232] In some embodiments, the second information determined by the first network device 102 is the same as or different from the configuration requirement information reported by the second network device 103 .

[0233] Step S2104 : The first network device 102 sends second information to the terminal 101 .

[0234] In some embodiments, the first network device 102 may send the second information via high-layer signaling.

[0235] Optionally, the first network device 102 sends the second information via Radio Resource Control (RRC) signaling.

[0236] In some embodiments, the terminal 101 receives the second information to obtain the pattern and / or purpose of the Pre-MG.

[0237] In some embodiments, before the terminal 101 uses the Pre-MG for measurement, the Pre-MG or the Pre-MG state must be in an activated state.

[0238] It is understandable that when the Pre-MG is in the activated state (Activated), the terminal 101 can measure the configured MO according to the Pre-MG. When the Pre-MG is in the deactivated state (Deactivated), the terminal 101 cannot use the Pre-MG for measurement.

[0239] In some embodiments, terminals 101 with different capabilities may support different Pre-MG activation or deactivation mechanisms.

[0240] For example, the Pre-MG may be a UE autonomous activation / deactivation mechanism or a network controlled activation / deactivation mechanism.

[0241] The embodiment of the present disclosure is described by taking the autonomous activation or deactivation mechanism of the terminal 101 as an example.

[0242] In some embodiments, the Pre-MG is determined by the terminal 101 to be in an active state when a first condition is met.

[0243] Optionally, a group of serving cells associated with the first network device 102 may be recorded as a Master Cell Group (MCG), and the MCG may include a Primary Cell (PCell) and a Secondary Cell (SCell).

[0244] Optionally, a group of serving cells associated with the second network device 103 may be recorded as a secondary cell group (SCG), and the SCG may include a primary secondary cell (PSCell) and an SCell.

[0245] In some embodiments, the first condition includes at least one of the following:

[0246] Bandwidth Part (BWP) switching under MCG;

[0247] Activation or deactivation of SCell(s) under MCG;

[0248] Addition or removal of any measurement object(s) under MCG;

[0249] Addition, release, or change of a SCell in carrier aggregation

[0250] BWP switching under SCG;

[0251] Addition or removal of measurement objects under SCG;

[0252] activation or deactivation of SCG;

[0253] Addition, release or change of Primary Secondary Cell (PSCell) under SCG;

[0254] Addition, release, or change of SCells under the SCG.

[0255] Optionally, the BWP switching may be DCI (Downlink Control Information), timer or RRC based active BWP switching.

[0256] Optionally, when any one or more of the above first conditions exist, the terminal 101 will be triggered to determine whether the Pre-MG is in an activated state.

[0257] Optionally, when the first condition is triggered, the terminal 101 may use the method in Table 1 to determine the activation state, that is, determine whether the Pre-MG is in the activated state or the deactivated state.

[0258] Table 1

[0259] Among them, the measurement within the frequency band based on SSB must meet the following requirements: the center frequency of the serving cell SSB is the same as the center frequency of the neighboring cell SSB, and the subcarrier spacing (SCS) of the serving cell SSB and the neighboring cell SSB is the same.

[0260] Optionally, the terminal 101 may determine the state of the Pre-MG based on an autonomous activation or deactivation mechanism, the received second information and the first condition.

[0261] Step S2105: Terminal 101 performs measurement according to the second information.

[0262] In some embodiments, when the Pre-MG is activated, terminal 101 can determine the Pre-MG used by the configured MO based on the purpose of the Pre-MG in the second information. For example, if the purpose of the Pre-MG corresponds to the pre-configured per-UE MG, different MOs can use the same Pre-MG for measurement. Terminal 101 can perform MO measurements within the duration of the Pre-MG based on the Pre-MG pattern in the second information.

[0275] Figure 2b is an interactive diagram of an information interaction method according to an embodiment of the present disclosure. As shown in Figure 2b, the present disclosure embodiment relates to an information interaction method, which includes:

[0276] Step S2201 : The first network device 102 sends third information to the second network device 103 .

[0277] In some embodiments, the implementation of step S2201 can refer to the relevant implementation of step S2101 and will not be repeated here.

[0278] In step S2202 , the second network device 103 sends first information to the first network device 102 .

[0280] Step S2203: The first network device 102 determines second information according to the first information.

[0281] In some embodiments, the implementation of step S2203 can refer to the relevant implementation of step S2103 and will not be repeated here.

[0282] Step S2204 : The first network device 102 sends second information to the terminal 101 .

[0283] In some embodiments, the implementation of step S2204 can refer to the relevant implementation of step S2104 and will not be repeated here.

[0284] In some embodiments, terminals 101 with different capabilities may support different Pre-MG activation or deactivation mechanisms. The embodiments of the present disclosure are described using a network-controlled activation or deactivation mechanism as an example.

[0285] In some embodiments, the first network device 102 controls whether the Pre-MG is in an activated state.

[0286] In step S2205 , the second network device 103 sends fourth information to the first network device 102 .

[0287] In some embodiments, the fourth information is used to indicate activation states of Pre-MGs of different purposes expected by the second network device 103 .

[0288] Optionally, depending on different purposes, the Pre-MG includes a pre-configured per-UE MG, a pre-configured per-FR1 MG, or a pre-configured per-FR2 MG. MGs for different purposes have different applications. For example, a pre-configured per-UE MG is applicable to various measurement scenarios of terminal 101, and terminal 101 can perform all measurements requiring measurement intervals based on this MG. For another example, for a pre-configured per-FR1 MG or a pre-configured per-FR2 MG, terminal 101 can select an MG applicable to the corresponding FR based on the FR where the target frequency to be measured and the serving cell frequency are located, such as FR1 or FR2.

[0289] Optionally, the second network device 103 may report the activation status requirement of a pre-configured per-UE MG, a pre-configured per-FR1 MG, or a pre-configured per-FR2 MG.

[0290] In some embodiments, the fourth information may be indication information.

[0292] In some embodiments, the first network device 102 receives the fourth information.

[0293] Step S2206 : The first network device 102 sends fifth information to the terminal 101 .

[0294] In some embodiments, the first network device 102 can determine the fifth information.

[0295] Optionally, the first network device 102 determines the fifth information according to the received fourth information.

[0296] In some embodiments, the fifth information may be indication information.

[0297] In some embodiments, the fifth information is used to indicate whether the Pre-MG is in an activated state or a deactivated state, that is, the first network device 102 controls whether the Pre-MG is in an activated state by sending the fifth information.

[0298] Optionally, one bit may be used to indicate whether the Pre-MG is in an activated state. When the value of this bit is 1, it indicates that the Pre-MG is in an activated state; when the value of this bit is 0, it indicates that the Pre-MG is in a deactivated state.

[0299] In the first example, the first network device 102 belongs to the first communication system, and the Pre-MG is a Pre-MG applicable to the first frequency range FR1, ie, a pre-configured per-FR1 MG; or, the Pre-MG is a Pre-MG applicable to a terminal, ie, a pre-configured per-UE MG.

[0300] In this example, the first communication system may be EN-DC and NGEN-DC. In the first communication system, the first network device 102 corresponds to an Evolved Universal Terrestrial Radio Access Network such as 4G.

[0301] In this example, the first network device 102 may carry the fifth information in a configuration message, such as RRCResume / RRCReconfiguration--->masterCellGroup.

[0302] In the second example, the first network device belongs to the second communication system, and the Pre-MG is at least one of the following: a Pre-MG applicable to FR1, a Pre-MG applicable to the second frequency range FR2, and a Pre-MG applicable to a terminal. It is understood that the terminal 101 may be configured with one of the three, or the terminal 101 may be configured with a Pre-MG applicable to FR1 or FR2 and a Pre-MG applicable to a terminal.

[0303] In this example, the second communication system may be NE-DC or NR-DC. In the second communication system, the first network device 102 corresponds to the NR network.

[0304] In this example, the first network device 102 may carry the fifth information in a configuration message, such as RRCResume / RRCReconfiguration--->masterCellGroup.

[0305] It is worth noting that EN-DC, NGEN-DC and NE-DC are all DC architectures in non-standalone networking (NSA).

[0306] Step S2207: Terminal 101 performs measurement according to the second information.

[0307] In some embodiments, the implementation of step S2207 can refer to the relevant implementation of step S2105 and will not be repeated here.

[0308] In some embodiments, when the Pre-MG is in an active state, the terminal 101 may perform measurements.

For example, step S2201 may be implemented as an independent embodiment, steps S2202 to S2203 may be implemented as independent embodiments, steps S2202 to S2204 may be implemented as independent embodiments, and steps S2202 to S2106 may be implemented as independent embodiments, but the present invention is not limited thereto.
