In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0184] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0185] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements 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), or a Next Generation Core (NGC).

[0186] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0187] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it.

[0188] Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0189] The embodiments disclosed herein 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), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0190] In this embodiment of the disclosure, in carrier aggregation (CA) or data aggregation (DC) scenarios, the first network device 102 and the second network device 103 can correspond to two nodes in the communication system. For example, in a DC scenario, the first network device 102 corresponds to the master node (MN), and the second network device 103 corresponds to the secondary node (SN).

[0191] In this embodiment of the disclosure, the MO (Mobile Origin) configured in the network device, such as the first network device 102, corresponds to the signal of the neighboring cell or other carrier to be measured. Due to manufacturing costs and shape constraints, the terminal 101 operates at the same frequency at any given time, and the terminal 101 can measure the MO centered on that frequency at that time. For example, the terminal 101 can easily measure neighboring cell signals at the same frequency as its current operating frequency, while simultaneously receiving and transmitting data in the serving cell.

[0192] In this embodiment of the disclosure, when terminal 101 performs neighbor cell measurements for different frequencies, such as inter-frequency neighbor cells or other systems, such as other wireless networks with a frequency of 5G NR, it needs to suspend communication with the serving cell, including suspending data reception (RX) or transmission (TX) with the serving cell, and needs to adjust the radio frequency (RF) module to configure the frequency to perform the measurement of this part of the neighbor cells. After a period of time, the connection with the serving cell is restored. The time interval (MG) during which terminal 101 suspends communication with the serving cell to measure inter-frequency neighbor cells or other wireless neighbor cells is defined as the time interval.

[0193] In this embodiment of the disclosure, a network device, such as the first network device 102, may configure multiple MOs for the terminal 101. Among these, there may be multiple MOs that need to be measured based on MG, and multiple MOs may compete for the same set of MG. In this case, the terminal 101 needs to determine the scaling factor of each MO to determine the corresponding measurement requirements, such as the measurement interval in the time domain.

[0194] In this embodiment of the disclosure, the network device, such as the first network device 102, is configured with two types of MGs:

[0195] One type is the terminal-based measurement gap (per-UE measurement gap), where the UE performs all measurements that require a measurement gap based on this MG;

[0196] Another approach is per-FR measurement gap, where the measurement range (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, terminal 101 performs MG-based measurements based on the FR MG configuration. First network device 102 can configure per-FR1 MG and / or per-FR2 MG based on the capability information (independentGapConfig) reported by terminal 101. FR1-based systems include evolved universal terrestrial radio access (E-UTRA), universal terrestrial radio frequency division duplex (UTRA-FDD), and NR; FR2-based systems include NR. Understandably, this capability information indicates that terminal 101 supports the ability to perform independent FR1 and FR2 measurements separately on independent radio links.

[0197] In this embodiment of the disclosure, the scenario of configuring the measurement interval in a DC scenario includes the following two cases:

[0198] If per-UE MG is configured, the second network device 103 will inform the first network device 102 of the FR1 and FR2 measurement frequency band lists configured by the second network device 103. The first network device 102 will then determine the measurement interval pattern (MG pattern) and interval sharing configuration. It is understood that the interval sharing configuration is used to handle measurement conflict scenarios where different MOs compete for the same set of MGs.

[0199] If per-FR MG is configured, the measurement interval configuration varies depending on the communication system, for example:

[0200] 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 5G core network, the second network device 103 informs the first network device 102 of the FR1 measurement frequency band list configured by the second network device 103, and the first network device 102 (eNB) determines the FR1 spacing pattern and spacing sharing configuration; or, the first network device 102 informs the second network device 103 of the FR2 measurement frequency band list configured by the first network device 102, and the second network device 103 (en-gNB) determines the FR2 spacing pattern and spacing sharing configuration, and sends it to the terminal 101.

[0201] In NR eNB Dual Connection (NE-DC), the first network device 102 informs the second network device 103 of the per-UE or per-FR1 MG pattern. The second network device 103 can provide the first network device 102 with an interval request without carrying a frequency band list. In NR Dual Connection (NR-DC), the first network device 102 informs the second network device 103 of the per-UE, per-FR1, or per-FR2 MG pattern. The second network device 103 can inform the first network device 102 of the FR1 and FR2 measurement frequency band list configured by the second network device 103. At this time, the first network device 102 (gNB) determines the MG pattern and interval sharing configuration of FR1 and FR2.

[0202] In this embodiment, there are three types of measurement gaps (MGs): concurrent measurement gaps, pre-configured measurement gaps (Pre-MGs), and network-controlled small gaps (NCSGs). Pre-MGs are suitable for standalone (SA) networks. Furthermore, in DC scenarios, since most MGs are configured by the first network device 102, the demand for MGs in the frequency band of the second network device 103 node cannot be promptly known to the first network device 102.

[0203] Figure 2a This is an interactive schematic diagram illustrating an information interaction method according to an embodiment of this disclosure. For example... Figure 2a As shown, the embodiments of this disclosure relate to an information interaction method, which includes:

[0204] In step S2101, the first network device 102 sends third information to the second network device 103.

[0205] In some embodiments, the first network device 102 corresponds to MN, and the second network device 103 corresponds to SN.

[0206] In some embodiments, the third information is used to instruct the first network device 102 to configure Pre-MG.

[0207] In some embodiments, the third information may be instruction information.

[0208] In some embodiments, third information may be transmitted via configuration information such as CG-ConfigInfo messages or other messages.

[0209] In some embodiments, the first network device 102 sends third information to the second network device 103 through an inter-node interface such as an Xn or X1 interface.

[0210] Optionally, the first network device 102 informs the second network device 103 by sending a third message: 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.

[0211] In some embodiments, the second network device 103 receives the third information.

[0212] In step S2102, the second network device 103 sends the first information to the first network device 102.

[0213] In some embodiments, the first information is used to indicate the configuration requirements of the Pre-MG.

[0214] In some embodiments, the first information may be indication information.

[0215] In some embodiments, the first information may be transmitted by configuration information such as CG-Config messages or other messages.

[0216] In some embodiments, the configuration requirements information includes at least one of the following:

[0217] Does the second network device 103 request to configure Pre-MG?

[0218] The second network device 103 is expected to achieve the purpose of Pre-MG.

[0219] Optionally, a 1-bit indicator can be used to indicate whether Pre-MG configuration is requested. If the 1-bit value is 1, it indicates that the second network device 103 has requested Pre-MG configuration; if the 1-bit value is 0, it indicates that the second network device 103 has not requested Pre-MG configuration.

[0220] Optionally, an enumeration method can be used to indicate whether Pre-MG configuration is requested. 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.

[0221] Alternatively, the purpose of Pre-MG can also be referred to as the gap purpose or the measurement purpose.

[0222] Alternatively, depending on the purpose of Pre-MG, Pre-MG can be divided into: pre-configured per-UE MG and pre-configured per-FR MG.

[0223] Optionally, the pre-configured per-FR MG can be further divided into pre-configured per-FR1 MG or pre-configured per-FR2 MG.

[0224] In some embodiments, the second network device 103 may send first information to the first network device 102 through an inter-node interface such as an Xn or X1 interface.

[0225] Optionally, the second network device 103 informs the first network device 102 by sending a first message whether the second network device 103 requests to configure Pre-MG. The second network device 103 may also inform the first network device 102 by sending a first message about the purpose of the Pre-MG supported by the second network device 103, that is, the supported Pre-MG.

[0226] In some embodiments, the first network device 102 receives the first information.

[0227] In step S2103, the first network device 102 determines the second information based on the first information.

[0228] In some embodiments, the second information includes the Pre-MG pattern and / or purpose.

[0229] Optionally, the pattern of the Pre-MG may include at least one of the following: the starting offset of the Pre-MG, the duration of the Pre-MG, and the repetition period of the Pre-MG.

[0230] Alternatively, the purpose of Pre-MG is to indicate whether Pre-MG is pre-configured per-UE MG, pre-configured per-FR1 MG, or pre-configured per-FR2 MG.

[0231] In some embodiments, the second information determined by the first network device 102 may be the same as or different from the configuration requirement information reported by the second network device 103.

[0232] In step S2104, the first network device 102 sends the second information to the terminal 101.

[0233] In some embodiments, the first network device 102 may send the second information via higher-layer signaling.

[0234] Optionally, the first network device 102 sends the second information via Radio Resource Control (RRC) signaling.

[0235] In some embodiments, terminal 101 receives the second information to learn the pattern and / or purpose of the Pre-MG.

[0236] In some embodiments, before the terminal 101 uses Pre-MG for measurement, the Pre-MG or Pre-MG state must be active.

[0237] Understandably, when the Pre-MG is in the activated state, terminal 101 can perform MO measurements based on the Pre-MG. When the Pre-MG is in the deactivated state, terminal 101 cannot use the Pre-MG for measurements.

[0238] In some embodiments, terminals 101 with different capabilities may support different Pre-MG activation or deactivation mechanisms.

[0239] For example, Pre-MG can be a UE autonomous activation / deactivation mechanism or a network-controlled activation / deactivation mechanism.

[0240] This disclosure describes an embodiment using the self-activation or deactivation mechanism of terminal 101 as an example.

[0241] In some embodiments, the Pre-MG is determined by the terminal 101 to be in an active state when a first condition is met.

[0242] Optionally, the group of serving cells associated with the first network device 102 may be referred to as the Master Cell Group (MCG), which may include primary cells (PCell) and secondary cells (SCell).

[0243] Optionally, the group of serving cells associated with the second network device 103 can be referred to as a secondary cell group (SCG). The SCG may include primary secondary cells (PSCell) and SCells.

[0244] In some embodiments, the first condition includes at least one of the following:

[0245] Switching of the Bandwidth Part (BWP) under MCG;

[0246] Activation or deactivation of SCell(s) under MCG;

[0247] Addition or removal of any measurement object(s) under MCG;

[0248] Adding, releasing, or changing a SCell in carrier aggregation under MCG

[0249] BWP switching under SCG;

[0250] Adding or removing measurement objects under SCG;

[0251] Activation or deactivation of SCG;

[0252] Adding, releasing, or changing primary and secondary cells (PSCells) under SCG;

[0253] Adding, releasing, or changing SCells under SCG.

[0254] Optionally, BWP switching can be based on downlink control information (DCI), timers, or RRC (DCI, timer, or RRC based active BWP switching).

[0255] Optionally, if any one or more of the above first conditions are met, the terminal 101 will be triggered to determine whether the Pre-MG is in an active state.

[0256] Optionally, when the first condition is triggered, the terminal 101 may use the method in Table 1 to determine the activation state, that is, to determine whether Pre-MG is in an active state or a deactivated state.

[0257] Table 1

[0258]

[0259]

[0260] Among them, the frequency band measurement based on SSB must meet the following requirements: the center frequency of the serving cell SSB and the center frequency of the neighboring cell SSB are the same, and the subcarrier spacing (SCS) of the serving cell SSB and the neighboring cell SSB are the same.

[0261] Optionally, terminal 101 may determine the state of Pre-MG based on the received second information and the first condition, using an autonomous activation or deactivation mechanism.

[0262] In step S2105, terminal 101 performs a measurement based on the second information.

[0263] In some embodiments, when the Pre-MG is active, the 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-UEMG, different MOs can all be measured using the same Pre-MG. The terminal 101 can perform MO measurements within the duration of the Pre-MG based on the pattern of the Pre-MG in the second information.

[0275] In some embodiments, see Figure 2a Other optional implementation methods described before or after the corresponding instruction manual.

[0276] Figure 2b This is an interactive schematic diagram illustrating an information interaction method according to an embodiment of this disclosure. For example... Figure 2b As shown, the embodiments of this disclosure relate to an information interaction method, which includes:

[0277] In step S2201, the first network device 102 sends third information to the second network device 103.

[0278] In some embodiments, the implementation of step S2201 can refer to the relevant implementation of step S2101, and will not be repeated here.

[0279] In step S2202, the second network device 103 sends the first information to the first network device 102.

[0280] In some embodiments, the implementation of step S2202 can refer to the relevant implementation of step S2102, and will not be repeated here.

[0281] In step S2203, the first network device 102 determines the second information based on the first information.

[0282] In some embodiments, the implementation of step S2203 can refer to the relevant implementation of step S2103, and will not be repeated here.

[0283] In step S2204, the first network device 102 sends the second information to the terminal 101.

[0284] In some embodiments, the implementation of step S2204 can refer to the relevant implementation of step S2104, and will not be repeated here.

[0285] In some embodiments, terminals 101 with different capabilities may support different Pre-MG activation or deactivation mechanisms. This disclosure describes a network-controlled activation or deactivation mechanism as an example.

[0286] In some embodiments, the Pre-MG is controlled by the first network device 102 to determine whether it is in an active state.

[0287] In step S2205, the second network device 103 sends the fourth information to the first network device 102.

[0288] In some embodiments, the fourth information is used to indicate the activation status of Pre-MG for different purposes that the second network device 103 expects.

[0289] Optionally, depending on the purpose, the Pre-MG includes a pre-configured per-UE MG, a pre-configured per-FR1 MG, or a pre-configured per-FR2 MG. The MGs for different purposes differ in their applications. For example, a pre-configured per-UE MG is suitable for various measurement scenarios of the terminal 101, and the terminal 101 can perform all measurements requiring measurement intervals based on this MG. Similarly, with pre-configured per-FR1 or pre-configured per-FR2 MGs, the terminal 101 can select the appropriate MG based on the FR (Frequency Reference Frame) where the target frequency and serving cell frequency are located, such as FR1 or FR2.

[0290] Optionally, the second network device 103 may report the activation status of pre-configured per-UE MG, pre-configured per-FR1 MG, or pre-configured per-FR2 MG.

[0291] In some embodiments, the fourth information may be indication information.

[0293] In some embodiments, the first network device 102 receives the fourth information.

[0294] In step S2206, the first network device 102 sends the fifth information to the terminal 101.

[0295] In some embodiments, the first network device 102 may determine the fifth information.

[0296] Optionally, the first network device 102 determines the fifth information based on the received fourth information.

[0297] In some embodiments, the fifth information may be instruction information.

[0298] In some embodiments, the fifth information is used to indicate whether the Pre-MG is in an active or deactivated state, that is, the first network device 102 controls whether the Pre-MG is in an active state by sending the fifth information.

[0299] Optionally, a 1-bit indicator can be used to indicate whether the Pre-MG is active. A value of 1 indicates that the Pre-MG is active; a value of 0 indicates that the Pre-MG is deactivated.

[0300] 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, i.e., pre-configured per-FR1 MG; or, the Pre-MG is a Pre-MG applicable to the terminal, i.e., pre-configured per-UE MG.

[0301] In this example, the first communication system can be EN-DC or NGEN-DC. In the first communication system, the first network device 102 corresponds to an evolved general terrestrial radio access network such as 4G.

[0302] In this example, the first network device 102 may carry the fifth information in a configuration message, such as RRCReconfiguration / RRCReconfiguration--->masterCellGroup.

[0303] 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 for FR1, a Pre-MG for the second frequency range FR2, and a Pre-MG for the terminal. It is understood that the terminal 101 may be configured with one of these three, or the terminal 101 may be configured with a Pre-MG for FR1 or FR2 and a Pre-MG for the terminal.

[0304] In this example, the second communication system can be either NE-DC or NR-DC. In the second communication system, the first network device 102 corresponds to an NR network.

[0305] In this example, the first network device 102 may carry the fifth information in a configuration message, such as RRCReconfiguration / RRCReconfiguration--->masterCellGroup.

[0306] It is worth noting that EN-DC, NGEN-DC, and NE-DC are all DC architectures in non-standalone (NSA) networking.

[0307] In step S2207, terminal 101 performs a measurement based on the second information.

[0308] In some embodiments, the implementation of step S2207 can refer to the relevant implementation of step S2105, and will not be repeated here.

[0309] In some embodiments, when Pre-MG is active, terminal 101 can perform measurements.

[0310] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2205. For example, step S2201 may be implemented as an independent embodiment, steps S2202 to S2203 may be implemented as an independent embodiment, steps S2202 to S2204 may be implemented as an independent embodiment, and steps S2202 to S2106 may be implemented as an independent embodiment, but are not limited thereto.

[0323] In some embodiments, terminals 101 with different capabilities may support different Pre-MG activation or deactivation mechanisms. This disclosure describes a network-controlled activation or deactivation mechanism as an example.

[0324] In some embodiments, the Pre-MG is controlled by the second network device 103 to determine whether it is in an active state.
