[0110] The method proposed in this disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance and subsequent communication technologies (such as 6G).

[0111] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 may include a first network node 101, a second network node 102, and a terminal 103.

[0112] In some embodiments, the method disclosed herein can be applied to a communication system. Optionally, the first network node can be a network-side master node (MN), the second network node can be a network-side secondary node (SN), and further, the second network node can be a source SN. The terminal connects to the MN and the source SN through a dual connectivity (DC) architecture.

[0113] In some embodiments, the terminal includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

The access network device may include at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system, but is not limited thereto.

[0115] 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 the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0116] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. 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.

[0117] 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.

[0118] 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 proposed 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 proposed in this disclosure are also applicable to similar technical problems.

[0119] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. 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.

[0120] 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), 6th generation mobile communication system (6G), 6G 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), and IEEE 802.16 (WiMAX, a registered trademark), 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. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0121] In 5G systems, a dual connectivity (DC) architecture can be adopted, which includes two cell groups: the master cell group (MCG), corresponding to the network-side master node (MN); and the secondary cell group (SCG), corresponding to the network-side secondary node (SN).

[0122] The MCG consists of one primary cell (or cell group) (PCell) and one or more secondary cells (or cell groups) (SCell). The SCG consists of one primary secondary cell (or cell group) (PSCell) and one or more SCells. PCell and PSCell can be collectively referred to as special cells (or cell groups) (SpCell).

[0123] In the MCG, there is a cell used to initiate initial access; this cell is called the PCell. As the name suggests, the PCell is the most "primary" cell in the MCG. The PCell in the MCG and the SCell in the MCG are combined through Carrier Aggregation (CA). In the MCG, the primary cell is the PCell, and the secondary cell is the SCell; in the SCG, the primary and secondary cells are the PSCell, and the secondary cell is the SCell. Because much signaling is only transmitted on the PCell and PSCell, for ease of description, the protocol also defines a concept called sPCell; PCell and PSCell are collectively referred to as sPCell.

[0124] The 5G Radio Access Network (NG-RAN) supports 5G New Radio Dual Connectivity (NR-NR DC, NR-DC), where the UE connects to one gNB acting as the MN and another gNB acting as the SN. The primary gNB connects to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also connect to the 5GC via the NG-U interface. Furthermore, the NR-DC can also be used for the UE to access a single gNB, simultaneously acting as both the MN and SN, and simultaneously configuring both the MCG and SCG.

[0125] In 5G systems, the network side can provide the terminal with one or more candidate configurations, where each candidate configuration can include one or more "cells (or cell groups)". The network side can subsequently control the terminal to change among these candidate configurations (e.g., changing the working cell (or cell group) from "cell (or cell group)-1" to "cell (or cell group)-2") via L1 (e.g., Downlink Control Information (DCI)) or L2 (Media Access Control-Control Element (MAC CE)) signaling. This control signaling can be called "cell change control signaling". This process can also be called Layer 1 / L2-triggered Mobility (LTM) process, i.e., LTM handover process.

[0126] LTM refers to the process where a base station receives an L1 measurement report from a terminal. Based on the received L1 measurement results, the base station can send a Cell Switch Command to the terminal via MAC CE to change the terminal's serving cell. The base station pre-sends multiple LTM candidate messages to the terminal via Radio Resource Control (RRC) signaling. When LTM is triggered, the base station indicates the LTM candidate message corresponding to the target cell to be accessed by sending a Cell Switch Command MAC CE. The terminal then applies the corresponding LTM candidate target configuration to complete the serving cell change. The network side's sending of a MAC CE to trigger the Cell Switch based on L1 measurement results enables it to respond to rapid channel changes and trigger handover promptly.

[0127] During LTM (Lead Time Management), early uplink and downlink synchronization for candidate cells is supported, enabling RACH-less LTM Cell Switching. Currently, two methods are supported for obtaining the TA (Target Acquisition) values ​​of LTM candidate cells in advance: early TA acquisition and UE-based TA measurement. Performing early uplink and downlink synchronization for candidate cells to achieve RACH-less LTM Cell Switching effectively reduces data interruptions during handover.

[0128] In some embodiments, the terms "uplink", "uplink", and "physical uplink" can be used interchangeably, as can the terms "downlink", "downlink", and "physical downlink", as well as the terms "sidelink", "sidelink", "sidelink communication", "sidelink communication", "direct connection", "direct link", "direct communication", and "direct link communication".

[0129] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0130] LTM supports Subsequent LTM, meaning that the terminal does not release the LTM configuration after each LTM cell handover. This allows the terminal to continue performing subsequent cell handovers after mobility is established, without RRC reconfiguration or reset. Supporting Subsequent LTM effectively reduces signaling overhead.

[0131] Currently, both intra-CU and inter-DU LTM have been standardized; further LTM enhancements are planned, including support for inter-CU LTM, condition-triggered LTM, and event-triggered L1 measurement reporting. This will further improve LTM performance and broaden its applicability.

[0132] In NR-DC, the UE can receive two independent LTM configuration messages (ltm-Config): the ltm-Config associated with the MCG, which is included in the RRC Reconfiguration message received via SRB1; and the ltm-Config associated with the SCG, which is included in the RRC Reconfiguration message received via SRB3, or embedded in the RRC Reconfiguration message received via SRB1.

[0133] If the UE receives two independent ltm-Configs: the UE maintains two independent ltm-Configs; the UE maintains two independent VarLTM-ServingCellNoResetIDs, one for each ltm-Config; the UE maintains two independent VarLTM-ServingCellUE-MeasuredTA-IDs, one for each ltm-Config; unless otherwise expressly specified, the UE independently executes all protocol-related procedures for each ltm-Config and its associated VarLTM-ServingCellNoResetID and VarLTM-ServingCellUE-MeasuredTA-ID.

[0134] Layer 1 (L1) measurements for LTM can include the following.

[0135] 1) L1 measurement reporting triggered by network (NW)

[0136] Currently, L1 measurements have been enhanced, supporting both intra-frequency and inter-frequency L1 measurements, but only L1-RSRP measurements based on the Synchronization Signal Block (SSB) are supported.

[0137] Existing L1 measurements support the reporting of semi-persistent and aperiodic data on PUSCH, as well as the reporting of both semi-persistent and periodic data on PUCCH.

[0138] Enhancements to L1 measurements include the following aspects: CSI-RS measurements; L1-SINR measurements; event-triggered L1 measurement reporting; and enhancements to current L1 measurements.

[0139] In the existing process, the LTM cell switch command is generated by the S-DU. In the LTM of the Intra-CU, the source base station distributed unit (Source gNB-DU, S-gNB-DU) makes cell switch decisions. The S-gNB-DU determines the candidate target cell to trigger LTM access based on the L1 measurement results reported by the terminal. Then, the S-gNB-DU sends the cell switch command to the terminal.

[0140] 2) Event-based L1 measurement reporting

[0141] To reduce measurement reports and improve mobility robustness, event-triggered measurement reports are currently supported. Event-triggered measurement reports can assist the NW side in selecting the target beam and / or cell for triggering early synchronization, or assist the NW side in selecting the target cell and / or the corresponding beam when triggering LTM cell handover.

[0142] A measurement report can be triggered when the measurement result of L1 meets the following event.

[0143] Event LTM2: Serving cell beam quality is worse than an absolute threshold; Event LTM3: Candidate cell beam quality is better than serving cell beam quality, and candidate cell beam quality exceeds the serving cell beam quality threshold; Event LTM4: Candidate cell beam quality is better than an absolute threshold; Event LTM5: Serving cell beam quality is worse than absolute threshold 1 and candidate cell beam quality is better than another absolute threshold 2.

[0144] The serving cell's beam is the current beam, which is the beam indicated by the Transmission Configuration Indication (TCI) state. The candidate cell's beam is any one or more beams configured in the candidate reference signal configuration (or measurement resource configuration).

[0145] Event-based L1 measurement reporting is sent to the network via MAC CE messages. Measurement events are configured in the serving cell configuration and are associated with the configuration of measurement resources.

[0146] For L1 LTM measurement configuration, as described below, LTM measurement configuration is divided into LTM measurement resource configuration and LTM measurement reporting configuration:

[0147] The LTM measurement resource configuration is universal for all LTM candidate cells. Regardless of which cell is the serving cell, its corresponding LTM measurement resource configuration is the same set of LTM measurement resources. The LTM reporting configuration is configured for each LTM candidate cell and includes the corresponding serving cell configuration for this LTM candidate cell. When it successfully serves a cell, the UE reports the LTM measurement results based on this configuration.

[0148] For L1 LTM measurement resource configuration, LTM measurement resource configuration is included in LTM configuration; for L1 LTM reporting configuration, LTM reporting configuration is included in the serving cell configuration.

[0149] In 5G systems, terminals can implement condition-triggered mobility procedures based on network "pre-configured conditions" and the corresponding "pre-configured cells (or cell groups)". When the terminal meets the "pre-configured conditions" (e.g., a specific measurement event), the terminal changes its serving cell (or cell group) to the "pre-configured cell (or cell group)". This "condition-triggered mobility procedure" includes:

[0150] Conditional Handover (CHO); Conditional Primary / Secondary Cell (or Cell Group) Addition (CPA); Conditional Primary / Secondary Cell (or Cell Group) Change (CPC); Conditional LTM (C-LTM). Conditional LTM can be used for both MCG and SCG changes.

[0151] Traditional methods support LTM for primary cell groups at the same frequency (inter-gNB MCG LTM) and LTM for secondary cell groups initiated by secondary nodes at different frequencies (SN-initiated inter-SN SCG LTM). For SN-initiated inter-SN SCG LTM, unlike the Rel-18 LTM for secondary cell groups at the same frequency (intra-SN SCG LTM, which is configured via SN RRC messages), inter-SN SCG LTM is configured via RRC messages from the MN. Its candidate configuration and reference configuration are also configured via MN RRCReconfiguration messages.

[0152] Since the LTM (Inter-CU SCG LTM) is initiated by the secondary node, the corresponding L1 measurement resource configuration needs to be determined by the source SN. Therefore, the serving SN can trigger SCG LTM based on the L1 measurement results. However, configuring the L1 measurement configuration of SCG LTM via MN RRCReconfiguration is currently not supported. How to configure the L1 measurement configuration of SCG LTM via MN RRCReconfiguration needs further investigation, and the relevant measurement resource identifiers need to be coordinated between the MN and the S-SN. If it is still configured via the SN, how it is associated with the SCG LTMDisandidate configuration configured by MN RRCReconfiguration also needs to be clarified.

[0153] Therefore, in order to solve the above-mentioned technical problems, this disclosure proposes a communication method. For two scenarios, where the L1 measurement corresponding to SCG LTM is configured by MN and the L1 measurement corresponding to SCG LTM is configured by SN, a corresponding measurement resource configuration identifier negotiation method, a measurement resource configuration method, and a method for associating measurement resource configuration with LTM candidate information are proposed respectively.

[0154] The following is a schematic diagram of a communication method provided in this disclosure. Embodiments of this disclosure relate to a communication method that can be executed by a communication system, such as the communication system 100 shown in Figure 1. The communication system includes a first network node 101, a second network node 102, and a terminal 103. The communication method may include the following specific methods:

[0155] Figure 2 is one of the interactive schematic diagrams of the communication method provided in this embodiment of the present disclosure. As shown in Figure 2, the method includes the following steps:

[0156] Step 2101: The first network node sends the first configuration identifier information to the second network node.

[0157] In some embodiments, the information related to the first configuration identifier includes at least one of the following: the number of first configuration identifiers; the value of the first configuration identifier; and the set of first configuration identifiers. Optionally, the number of first configuration identifiers may be one or more, that is, the number of first configuration identifiers is greater than or equal to 1, and the information related to the first configuration identifier may include the values ​​of one or more first configuration identifiers.

[0158] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0159] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" can be used interchangeably. For example, a codebook can be a collection of one or more codewords / precoding matrices.

[0160] In some embodiments, a first configuration identifier is used to identify first configuration information, which is configuration information related to measurement.

[0161] For example, the measurement includes, but is not limited to, any one or more of the following measurements:

[0162] L1 measurement, LTM measurement, beam measurement configuration, L2 measurement, L1 / L2 measurement, L1 LTM measurement, L3 measurement, RRM measurement, cell measurement, etc., are all or one of these. In some embodiments, measurement-related configuration information can be used directly or indirectly to trigger mobility.

[0163] For example, the mobility includes any one or more network-configured mobility operations;

[0164] For example, the network side pre-configures the corresponding mobility operations for candidate cells (or cell groups), including mobility triggered by PHY, MAC CE, RRC, and / or mobility triggered by measurement events (L1 / L2 events, and / or RRM events).

[0165] In some embodiments, the first configuration identifier is used to identify first configuration information, which is configuration information for measurement resources used for measurement. For example, the first configuration information is configuration information for Layer 1 measurement corresponding to Layer 1 or Layer 2 triggered mobility LTM for a secondary cell group (SCG). The first configuration information can be used to configure L1 measurement resources corresponding to SCG LTM. Optionally, the first configuration identifier is an available configuration identifier, which is available to the second network node, and the first configuration identifier has not yet been configured to the terminal.

[0166] For example, the LTM measurement can also be referred to as L1 measurement, LTM measurement, beam measurement configuration, L2 measurement, L1 / L2 measurement, L1 LTM measurement, etc.

[0167] In some embodiments, the first configuration information can also be used to configure any one or more of the following: information related to the reference signal under test; information related to the measurement target; information related to the measurement object; reporting configuration information; and other information.

[0168] In some embodiments, the first network node may be, for example, an MN, and the second network node may be, for example, a source SN. Optionally, the first configuration information may be sent to the terminal by the MN, that is, the MN may configure the measurement resources corresponding to the L1 measurement for the terminal. Further, the MN's MCG may configure the measurement resources for the terminal, that is, the LTM configuration generated by the MN / SCG includes the L1 measurement configuration corresponding to the candidate PSCell of the SCG LTM.

[0169] Optionally, MN may refer to the service MN.

[0170] Optionally, in one example, as shown in Figure 4A, before the first network node sends the first configuration identifier information to the second network node, the method further includes: the SN initiating the preparation process for SCG LTM and sending a message to the MN, wherein the message may be an SN Change Required message; the MN requests candidate SNs (T-SNs (also known as Candidate SNs, C-SNs; and / or candidate target SNs, and / or potential target SNs, and / or target SNs, etc.)) to allocate resources for the terminal, wherein the resources may include SCG LTM candidate cells and related configurations. Optionally, the MN may request the T-SNs through an SN Addition Request; each candidate SN (T-SN) sends an SN Addition Request Acknowledgment to the MN, which includes L1 Measurement Reference Signal (RS) Configuration and / or Candidate Config, where the Candidate Config contains the configuration of the candidate SCG / PSCell; for SN termination bearers using MCG resources, the MN sends an Xn-U address indication message to the candidate SNs. The Indication provides Xn-U downlink transport network layer (DL TNL) address information.

[0171] In other words, the first network node can directly determine the first configuration identifier information and send the first configuration identifier information to the second network node.

[0172] In some embodiments, sending first configuration identifier related information to a second network node includes: sending a first message to the second network node, the first message including first configuration identifier related information, and / or the first message also including reference signal configuration information corresponding to one or more candidate cells.

[0173] The first message can be an SN Modification Request, and the reference signal configuration information corresponding to one or more candidate cells can be determined based on the SNAddition Request Acknowledge received from the candidate SN (T-SN). That is, the reference signal configuration information corresponding to the candidate cells can also include the L1 RS configuration received from the T-SN. The first configuration identifier information and the reference signal configuration information corresponding to one or more candidate cells can both be used by the second network node to generate the first configuration information.

[0174] Optionally, the first message may include first configuration identifier related information and reference signal configuration information corresponding to one or more candidate cells. In this case, the second network node can generate the first configuration information based on the first configuration identifier related information and the reference signal configuration information corresponding to one or more candidate cells.

[0175] Optionally, in one example, as shown in Figure 4A, before the first network node sends the first configuration identifier information to the second network node, the method further includes: the second network node (SN) sending a second message to the first network node (MN), the second message being used to request the initiation of the SCG mobility preparation process, the second message including the requested configuration identifier information, wherein the second message may be an SN Change Required message; the MN requests the candidate SN (T-SN (also known as the Candidate SN, C-SN)) to allocate resources for the terminal, wherein the resources may include SCG LTM candidate cells and related configurations, optionally, the MN may request the T-SN through an SN Addition Request; each candidate SN (T-SN) sends an SN Addition Request Acknowledgment to the MN, which includes the L1 Measurement Reference Signal (RS) Configuration and / or the Candidate Config, this Candidate... The Config contains the configuration of candidate SCG / PSCell; for SN termination bearers using MCG resources, the MN provides Xn-U downlink transport network layer (DL TNL) address information in the Xn-U address indication message to the candidate SN.

[0176] In other words, the second network node can request configuration identifiers from the first network node. The second network node can make a request to the first network node by sending configuration identifier-related information to the first network node, such as sending the number of configuration identifiers.

[0177] In some embodiments, sending first configuration identifier related information to a second network node includes: sending a first message to the second network node, the first message including first configuration identifier related information, and / or the first message also including reference signal configuration information corresponding to one or more candidate cells.

[0178] The first message can be an SN Modification Request, and the reference signal configuration information corresponding to one or more candidate cells can be determined based on the SNAddition Request Acknowledge received from the candidate SN (T-SN). That is, the reference signal configuration information corresponding to the candidate cells can also include the L1 RS configuration received from the T-SN. The first configuration identifier information and the reference signal configuration information corresponding to one or more candidate cells can both be used by the second network node to generate the first configuration information.

[0179] Optionally, the method further includes: the first network node determining first configuration identifier related information based on the requested configuration identifier related information. In other words, the first network node can determine the first configuration identifier related information according to the second message and send the first configuration identifier related information to the second network node. For example, the first network node can generate a set of configuration identifiers based on the number of configuration identifiers requested by the second network node. Optionally, the first message may include the first configuration identifier related information and reference signal configuration information corresponding to one or more candidate cells. In this case, the second network node can generate first configuration information based on the first configuration identifier related information and the reference signal configuration information corresponding to one or more candidate cells.

[0180] Optionally, in one example, as shown in Figure 4B, before the first network node sends the first configuration identifier information to the second network node, the method further includes: the SN initiating the preparation process for SCG LTM and sending a message to the MN, wherein the message may be an SN Change Required message; the MN requests the candidate SN (T-SN (also known as the Candidate SN, C-SN)) to allocate resources for the terminal, wherein the resources may include SCG LTM candidate cells and related configurations. Optionally, the MN may request the T-SN via an SN Addition Request; each candidate SN (T-SN) sends an SN Addition Request Acknowledgment to the MN, which includes the L1 Measurement Reference Signal (RS) Configuration and / or the Candidate Config, which contains the configuration of the candidate SCG / PSCell; for SN termination bearers using MCG resources, the MN provides the Xn-U downlink transport network layer in the Xn-U address indication message to the candidate SN. Layer (DL TNL) address information.

[0181] [Revised according to Rule 91, 25.02.2025] In conjunction with the above example, as shown in Figure 4B, the method before the first network node sends the first configuration identifier related information to the second network node further includes: sending a third message to the second network node (step X), the third message including reference signal configuration information corresponding to one or more candidate cells; receiving a fourth message sent by the second network node (step Y), the fourth message including the configuration identifier related information of the request determined by the second network node based on the reference signal configuration information corresponding to one or more candidate cells.

[0182] In other words, the first network node can send reference signal configuration information corresponding to one or more candidate cells to the second network node. The second network node can determine configuration identifier information based on the reference signal configuration information of the one or more candidate cells, such as determining the number of configuration identifiers. Then, the second network node requests configuration identifiers from the first network node by sending configuration identifier information to the first network node. After receiving the requested configuration identifier information, the first network node can determine the first configuration identifier information based on the requested configuration identifier information and send the first configuration identifier information to the second network node for the second network node to generate the first configuration information.

[0183] Alternatively, the first network node may not need to send the first configuration identifier information to the second network node. Instead, the first network node may send only the reference signal configuration information corresponding to one or more candidate cells to the second network node. In this case, the second network node can directly generate the first configuration information based on the reference signal configuration information corresponding to one or more candidate cells.

[0184] Step 2102: The second network node sends the first configuration information to the first network node.

[0185] In some embodiments, as shown in FIG4A, a first network node (MN) may receive first configuration information sent by a second network node (source SN), the first configuration information being generated by the second network node based on first configuration identifier related information. Optionally, the first configuration information may be included in an SN Modification Request Acknowledgement.

[0186] In some embodiments, in response to the first configuration information being configuration information for measurement resources used for mobility measurements of the secondary cell group (SCG), the first configuration information and the third configuration information share the same measurement configuration identifier group, wherein the third configuration information is configuration information for measurement resources used for mobility measurements of the primary cell group (MCG). In other words, the measurement configuration may include the L1 measurement configuration for the SCG LTM and the L1 measurement configuration for the MCG LTM. Optionally, the L1 measurement configuration for the SCG LTM and the L1 measurement configuration for the MCG LTM may use the same configuration and share the same set of L1 measurement configuration identifiers.

[0187] In some embodiments, the sharing of the same measurement configuration identifier group between the first configuration information and the third configuration information includes at least one of the following: the first configuration identifier and the second configuration identifier corresponding to the third configuration information correspond to the same measurement configuration identifier group; the first configuration information and the third configuration information are included in the first measurement resource configuration information, wherein the first measurement resource configuration information includes one or more first measurement resource identifiers, wherein a first part of the first measurement resource identifier corresponds to the first configuration identifier, and a second part of the first measurement resource identifier corresponds to the second configuration identifier; and different values ​​correspond to different first measurement resource identifiers.

[0188] In some embodiments, in response to the first configuration information being configuration information for measurement resources used for measuring the mobility of the MCG, the first configuration information and the third configuration information share the same measurement configuration identifier group, wherein the third configuration information is configuration information for measurement resources used for measuring the mobility of the SCG.

[0189] In other words, L1 measurement configuration for SCG LTM and L1 measurement configuration for MCG LTM can be achieved using only one set of measurement configuration identifiers. Optionally, the first network node needs to send configuration identifier-related information to the second network node so that the second network node can generate the first configuration information. Optionally, the first network node can indicate the configuration identifier-related information available to the second network node. For example, the first network node can extract the configuration identifiers required to generate the third configuration information from the configuration identifier set and then send the new configuration identifier set to the second network node. Alternatively, the first network node can indicate the configuration identifier it uses to the second network node. After determining the configuration identifier used by the first network node (i.e., the configuration identifier corresponding to the configuration information of the measurement resources for MCG mobility measurement), the second network node can determine the configuration identifier used to generate the first configuration information from the configuration identifier set, i.e., the configuration identifier corresponding to the configuration information of the measurement resources for SCG mobility measurement.

[0190] In some embodiments, optionally, the first configuration information and the third configuration information correspond to different measurement configuration identifier groups, wherein the third configuration information is the configuration information of the measurement resources for MCG mobility measurement, and the second configuration identifier corresponding to the first configuration identifier and the third configuration information is included in different measurement configuration identifier groups. In other words, the L1 measurement configuration of SCG LTM and the L1 measurement configuration of MCG LTM can correspond to different configurations, the first configuration information can correspond to one measurement configuration identifier group, and the third configuration information can correspond to another measurement configuration identifier group.

[0191] Optionally, when the first configuration information and the third configuration information correspond to different measurement configuration identifier groups, the method further includes: receiving a fifth message sent by the second network node, the fifth message including the first configuration information encapsulated in a first format. The fifth message is an SN Modification Request Acknowledge message. The first format is a containing format, meaning the SN Modification Request Acknowledge message is sent in the form of an RRC container.

[0192] In some embodiments, optionally, as shown in FIG4A or 4B, after the second network node (S-SN) sends the first configuration information to the first network node (MN) (step 6), the method further includes: MN sending the L1 measurement resource configuration for SCG LTM sent by S-SN to T-SN, optionally, via an SN Modification Request message; T-SN updating the candidate target configuration based on this and sending the updated candidate target configuration to MN, optionally, via an SN Modification Request Acknowledge message; MN generating an MN RRCReconfiguration message (which may contain the first configuration information and the second configuration information) for the terminal based on the L1 measurement resource configuration for SCG LTM received in step 6 and the candidate target configuration for SCG LTM sent by T-SN received in steps 3 and 8, and sending it to the terminal (step 9); the terminal sending an RRC Reconfiguration Complete message to MN (step 10); MN sending an SN Change Confirm message to S-SN to inform S-SN of SCG. LTM is ready (Step 11).

[0193] Step 2103: The first network node sends the first configuration information and the second configuration information to the terminal.

[0194] In some embodiments, the second configuration information is candidate configuration information for one or more mobility systems. For example, the second configuration information may be configuration information for one or more SCG LTM candidate cells, and the second configuration information is determined by the first network node.

[0195] In some embodiments, the first configuration information and the second configuration information can be sent to the terminal simultaneously via the same message and / or sent to the terminal separately via different messages.

[0196] In some embodiments, the first network node may send only the first configuration information to the terminal, or the first network node may send only the second configuration information to the terminal. In some embodiments, the method further includes: receiving the first configuration information sent by the second network node; and sending the first configuration information to the terminal using a first field, wherein the first field is different from the second field, and the second field is used to send third configuration information to the terminal, the third configuration information being the configuration information of the measurement resources for MCG mobility measurement. In other words, it can be directly configured by the MN based on the L1 measurement resource configuration for SCG LTM sent by the SN, that is, the MN receives the first configuration information sent by the S-SN, instructs this configuration information to the terminal, at this time the MN can receive the first configuration information sent by the SN, obtain the content in the first configuration information, represent the first configuration information through the first field, and then the MN can add a second field, the second field being related to the third configuration information, and then send the first configuration information containing the first field and the second field to the terminal. That is, different fields of the first configuration information can be used to distinguish the first configuration information and the third configuration information. For example, the first field, such as sn-ltm-CSI-ResourceConfig-rxx, is distinct from the second field (such as ltm-CSI-ResourceConfigToAddModList or ltm-CSI-ResourceConfig).

[0197] In some embodiments, the method further includes: receiving first configuration information sent by a second network node; and sending the first configuration information to a terminal via first signaling information, wherein the first signaling information is different from the second signaling information, and the second signaling information is used to send third configuration information to the terminal, the third configuration information being configuration information of measurement resources for MCG mobility measurement. In other words, different signaling can be used to distinguish between the first configuration information and the third configuration information.

[0198] In some embodiments, the method further includes: a first network node receiving first configuration information sent by a second network node; the first network node transmitting the first configuration information to a terminal in a first format. The first format may be a CONTAINING format. Optionally, the first network node may receive the first configuration information from the second network node, and the first network node may only forward the received first configuration information. For example, the first network device may send the first configuration information and the third configuration information to the first terminal respectively.

[0199] In some embodiments, the CONTAINING format is ASN.1 Contents Constraint.

[0200] For example, when the message, parameter, or configuration corresponds to a "CONTAINING" constraint, the UE does not need to perform automatic decoding or reading of its contained types. The terminal can first use this Contents Constraint to decode the external PDU type. Then, it can decode or read its nested contained types through separate steps.

[0201] For example, the UE receives outer information carrying first configuration information sent by the MN. The UE first decodes the outer information and then decodes the first configuration information provided by the SN through separate supplementation.

[0202] For example, the information is constrained with "CONTAINING" to prevent it from being read by the first network node.

[0203] In some embodiments, the method further includes: receiving first configuration information sent by a second network node; and transmitting first signaling to a terminal in a first format, the first signaling including the first configuration information. In other words, the first configuration information can be transmitted to the terminal by sending the first signaling.

[0204] For example, transmitting the first configuration information to the terminal means that the first network node does not read the content of the first configuration information.

[0205] For example, the second network node can send the first configuration information to the first network node through the RRC container;

[0206] For example, the first configuration information can also be carried in cross-node RRC messages.

[0207] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0208] For example, in Figure 2;

[0209] Steps 2101 through 2103 can all be optional, and any one of them can be executed independently; and / or

[0210] Steps 2101 to 2103 can be combined arbitrarily, and any combination can be executed independently; and / or

[0211] 3. Steps 2101 to 2103 can be executed in different orders, and either order can be executed independently.

[0212] Figure 3 is a schematic diagram of one of the communication methods provided in this disclosure. As shown in Figure 3, the method includes the following steps:

[0213] Step 3101: The first network node sends the first configuration identifier information to the second network node.

[0214] In some embodiments, the first network node may send first configuration identifier related information to the second network node for the second network node to generate first configuration information; or the second network node may generate first configuration information based on reference signal configuration information corresponding to one or more candidate cells. For specific implementation methods, please refer to the method described in the embodiment of Figure 2 above, which will not be repeated here.

[0215] Step 3102: The second network node sends the first configuration information to the terminal.

[0216] In some embodiments, after determining the first configuration information, the second network node can send the first configuration information to the terminal. Optionally, the second network node can configure the L1 measurement configuration through the SN RRC message, that is, the SN can send the first configuration information to the terminal through the SN RRC message.

[0217] For example, the SNRRC message includes messages sent directly from the SN to the UE, such as messages sent to the UE via SRB3.

[0218] For example, the SNRRC message includes an RRC message generated by the SN that is forwarded via an RRC message carried by SRB1.

[0219] In other words, in the embodiment shown in Figure 2, the first network node can send first configuration information and second configuration information to the terminal, and in the embodiment shown in Figure 3, the first network node can send second configuration information to the terminal, and the second network node can send first configuration information to the terminal.

[0220] Step 3103: The first network node sends the second configuration information to the terminal.

[0221] In some embodiments, the terminal may receive second configuration information sent by a first network node and first configuration information sent by a second network node. That is, the terminal supports SCG LTM configured via messages from the SN (such as SN RRC Reconfiguration) and SCG LTM configured via messages from the MN (such as MN RRCReconfiguration). The terminal needs to specify whether the LTM candidate ID included in the L1 measurement resource configuration of the SCG LTM corresponds to the SCG LTM configured via the SN (such as via SN RRC Reconfiguration) or via the MN (such as via MN RRCReconfiguration).

[0222] In some embodiments, in response to the terminal being configured with SCG mobility configured by a second network node or SCG mobility configured by a first network node, the method further includes at least one of the following: determining that the mobility configuration information configured by the second network node for the terminal includes a mobility candidate configuration, and determining that first configuration information is associated with a mobility candidate configuration in the mobility configuration of the second network node; determining that the mobility configuration configured by the second network node for the terminal does not include a mobility candidate configuration, and determining that the first configuration information is associated with an LTM candidate configuration in the mobility configuration information of the first network node; determining that the mobility configuration information configured by the first network node for the terminal includes a mobility candidate configuration, and determining that the first configuration information is associated with a mobility candidate configuration in the mobility configuration of the first network node; determining that the mobility configuration configured by the first network node for the terminal does not include a mobility candidate configuration, and determining that the first configuration information is associated with a mobility candidate configuration in the mobility configuration information of the second network node.

[0223] In other words, when the UE does not support both the SCG LTM configured by SN RRC Reconfiguration and the SCG LTM configured by MN RRC Reconfiguration, if the SN LTM configuration stored in the terminal contains any LTM candidate configuration, then the L1 measurement resource configuration contained therein is associated with the LTM Candidate Config in the SN LTM configuration; if the SN LTM configuration stored in the terminal does not contain any Candidate Config, then the SN L1 measurement resource configuration contained therein is associated with the Candidate Config in the LTM configuration configured by MN; if the MN LTM configuration stored in the terminal contains any LTM candidate configuration, then the L1 measurement resource configuration contained therein is associated with the LTM Candidate Config in the MN LTM configuration; if the MN LTM configuration stored in the terminal does not contain any Candidate Config, then the MN L1 measurement resource configuration contained therein is associated with the Candidate Config in the LTM configuration configured by SN.

[0224] In some embodiments, in response to the terminal being simultaneously configured with SCG mobility configured by a second network node and SCG mobility configured by a first network node, the method further includes at least one of the following: receiving second information sent by the second network node, the second information indicating that first configuration information sent by the second network node is associated with the mobility configuration configured by the first network node; receiving second information sent by the second network node, the second information indicating that the first configuration information sent by the second network node is not associated with the mobility configuration configured by the first network node; receiving second information sent by the second network node, the second information indicating that the first configuration information sent by the second network node is associated with the mobility configuration configured by the second network node; receiving second information sent by the second network node, the second information indicating that the first configuration information sent by the second network node is not associated with the mobility configuration configured by the second network node.

[0225] In other words, when a terminal supports both SCG LTM configured with SN RRC Reconfiguration and SCG LTM configured with MN RRC Reconfiguration, it is necessary to determine whether the LTM candidate information corresponding to the reference signal RS configuration is configured with MN or SN (i.e., MN format or SN format) in the measurement resource configuration of the SCG LTM configured in the SN LTM configuration. Specifically, the second network node can send second information to the terminal. This second information can be the measurement resource configuration of the SCG LTM configured in the aforementioned SN LTM configuration, and it can be used to determine whether the LTM candidate information corresponding to the reference signal RS configuration is configured with MN or SN. For example, when the second information indicates MN configuration, the first configuration information is associated with the mobility configuration configured by the first network node, but not with the mobility configuration configured by the second network node; when the second information indicates SN configuration, the first configuration information is not associated with the mobility configuration configured by the first network node, but is associated with the mobility configuration configured by the second network node.

[0226] In some embodiments, the method further includes: receiving fourth configuration information sent by a first network device or a second network device, wherein the fourth configuration information is reporting configuration information; and determining the first configuration information corresponding to the reporting configuration information based on the first configuration identifier carried in the reporting configuration information. Optionally, the reporting configuration information can be used by the terminal to perform reporting, wherein the fourth configuration information can be included in the serving cell configuration and the source primary and secondary cell configuration in the candidate configuration. Optionally, the first configuration identifier carried in the reporting configuration is the identifier of the measurement resources for the SN configured by the MN.

[0227] In some embodiments, the steps and their optional implementations in other embodiments (such as the embodiment in Figure 2) described before or after this embodiment, as well as other related parts in the specification, can be referred to, which will not be repeated here.

[0228] For example, in Figure 3

[0229] Steps 3101 to 3103 are all optional steps, and any one of them can be executed independently; and / or

[0230] Steps 3101 to 3103 can be combined arbitrarily, and any combination can be executed independently; and / or

[0231] 3. Steps 3101 to 3103 can be executed in different orders, and either order can be executed independently.

[0232] The following is an exemplary description of the above method.

[0233] The method illustrated in this disclosure relates to a method for configuring SCG LTM measurement resources. The full details of this method are as follows.

[0234] Scenario 1: The L1 measurement corresponding to the SCG LTM is configured by MN / MCG, that is, the LTM configuration generated by MN / SCG contains the L1 measurement configuration corresponding to the candidate PSCell of the SCG LTM.

[0235] Option 1: The L1 measurement configuration of the SCG LTM and the L1 measurement configuration of the MCG LTM use the same configuration and share the same set of L1 measurement configuration identifiers. The MN needs to send a list of measurement configuration identifiers (i.e., ltm-CSI-ResourceConfigId) assigned to the SN for measuring candidate pscells to the source SN, so that the source SN can generate the corresponding measurement configuration based on this.

[0236] Option 2: The L1 measurement configuration for SCG LTM and MCG LTM corresponds to different configurations. MN configures the L1 measurement configuration generated by the source SN to the UE using the RRC container format, while the L1 measurement configuration generated by the source SN is sent to MN. MN then sends the L1 measurement configuration to the UE using the CONTAINING format.

[0237] Scenario 2: The L1 measurement corresponding to the SCG LTM is configured by SN / SCG, that is, the LTM configuration generated by SN / SCG contains the L1 measurement configuration corresponding to the candidate PSCell of the SCG LTM.

[0238] The L1 measurement configuration is configured via SN RRC messages. Since its SCG LTM Candidate configuration is configured via MN RRC messages, the L1 measurement configuration configured in this SN RRC message is associated with the candidate configuration of the MN RRC configuration.

[0239] The above measurement configuration refers to the measurement resource configuration, and the above measurement configuration identifier refers to the measurement resource identifier.

[0240] The above method will be explained and illustrated through specific embodiments below.

[0241] Example 1

[0242] Corresponding to Option 1 of Scenario 1, MN interacts with the source SN / candidate SN to configure the L1 measurement resource configuration identifier of SN LTM, as shown in Figure 4A, which is the measurement preparation process of SCG LTM.

[0243] Method 1

[0244] Step 1: SN initiates the preparation process for SCG LTM by sending a message to MN.

[0245] Step 2: The MN requests the T-SN (also known as the Candidate SN, C-SN) to allocate resources for the UE (preparing SCG LTM candidate cells and related configurations).

[0246] Step 3: Each candidate SN (T-SN) sends an L1 measurement reference signal RS configuration and / or a candidate target configuration to the MN. This candidate config contains the configuration of the candidate SCG / PSCell.

[0247] Step 4: For SNs terminating bearers using MCG resources, the MN provides Xn-U DL TNL address information in the Xn-U address indication message to the candidate SN.

[0248] Step 5: The MN sends the L1 RS configuration received from the T-SN and the set of identifiers available for the SN LTM L1 measurement resource configuration to the S-SN (via step 5 SN Modification Request), such as {5, 6, 7, 8}.

[0249] Step 6: The S-SN generates the L1 measurement resource configuration for SCG LTM based on this and sends it to the MN.

[0250] Step 7: MN sends the L1 measurement resource configuration for SCG LTM sent by S-SN to T-SN.

[0251] Step 8: The T-SN updates the candidate target configuration based on this and sends the updated candidate target configuration to the MN.

[0252] Step 9: Based on the L1 measurement resource configuration of SCG LTM received in step 6 and the candidate target configuration for SCG LTM sent by T-SN received in steps 3 and 8, MN generates an MN RRCReconfiguration message to be sent to the UE and sends it to the UE.

[0253] Step 10: The UE sends an RRC reconfiguration complete message to the MN.

[0254] Step 11: MN sends a secondary node switchover confirmation message (SN Change Confirm message) to S-SN to inform S-SN that SCG LTM is ready.

[0255] Method 2

[0256] Step 1: The SN initiates the preparation process for the SCG LTM by sending a message to the MN. In this request message (Step 1 SN Change Required), the number of identifiers required for the L1 measurement resource configuration is included, for example, 4.

[0257] Steps 2-4: Refer to steps 2-4 of Method 1, which will not be repeated here.

[0258] Step 5: Based on the number of identifiers requested by the S-SN in Step 1 of Method 2, the MN generates a set of identifiers available for the SN LTM L1 measurement resource configuration, such as {5, 6, 7, 8}, and sends it to the S-SN, which may also include the L1 RS configuration received by the T-SN.

[0259] Steps 6-10: Refer to steps 6-10 of Method 1, which will not be repeated here.

[0260] Method 3

[0261] As shown in Figure 4B, compared to Method 1 and Method 2, two additional steps, X and Y, are added to determine the number of identifiers required for the S-SN to configure the L1 measurement resources.

[0262] Steps 1-4: See steps 1-4 of Method 1 above, and will not be repeated here.

[0263] Step X: The MN sends the L1 RS configuration received from the T-SN to the S-SN via a third message; the third message can be a secondary node modification request (SN Modification Request) message.

[0264] Step Y: The S-SN determines the number of identifiers required for the L1 measurement resource configuration based on the L1 RS configuration in Step X, for example, 4, and sends it to the MN via a fourth message, which can be a secondary node modification request acknowledgment (SN Modification Request Acknowledge) message.

[0265] Step 5: Based on the number of identifiers requested by the S-SN in Step 1 of Method 3, MN generates a set of identifiers available for SN LTM L1 measurement resource configuration, such as {5, 6, 7, 8}, and sends it to the S-SN.

[0266] Steps 6-10: Refer to steps 6-10 of Method 1, which will not be repeated here.

[0267] Example 2

[0268] Corresponding to Option 2 of Scenario 1, the specific configuration method includes: using a separate field and / or information element (IE) to configure the L1 measurement resource configuration from S-SN for SCG LTM to distinguish it from the L1 measurement resource configuration from MN for MCG LTM, such as sn-ltm-CSI-ResourceConfig-rxx and SN-LTM-CSI-ResourceConfig-rxx.

[0269] Alternatively, as shown below, the L1 measurement resource configuration for SCG LTM can be configured directly by the MN based on the S-SN.

[0270] Optionally, as shown below, the UE can be configured with L1 measurement resource configuration from the S-SN for SCG LTM via the CONTAINING format.

[0271] Alternatively, configuration methods may include: using a separate field and / or IE to configure SCG LTMMN via MN RRC Reconfiguration.

[0272] Alternatively, as shown below, the L1 measurement resource configuration for SCG LTM can be configured directly by the MN based on the S-SN.

[0273] Optionally, as shown below, the UE can be configured with L1 measurement resource configuration from the S-SN for SCG LTM via the CONTAINING format.

[0274] The configuration based on the L1 measurement resource configuration for SCG LTM sent by S-SN may include: the L1 measurement resource configuration for SCG LTM generated by S-SN is configured through an incremental configuration method, including add / mod / remove list, which is used to configure, update or delete the L1 measurement resource configuration stored in the current UE.

[0275] The L1 measurement resource configuration from S-SN for SCG LTM in the specific configuration method is as follows.

[0276] The configuration method for the CONTAINING format includes: the S-SN sending the L1 measurement resource configuration for SCG LTM to the MN, specifically including the following process.

[0277] A) In step 6 of Figure 4A / Figure 4B above, the S-SN sends the L1 measurement resource configuration for SCG LTM generated by the SN to the MN via the SN Modification Request Acknowledge message. That is, the SN Modification Request Acknowledge message is sent through the RRC Container, and the included inter-node RRC message (e.g., CG-Config) contains the L1 measurement resource configuration for SCG LTM generated by the S-SN and provided to the MN, which then allocates it to the T-SN.

[0278] B) The L1 measurement resource configuration for SCG LTM is carried in CG-Config via the CONTAINING format.

[0279] C) The MN carries the L1 measurement resource configuration for SCG LTM in the CONTAINING format in the LTM configuration sent to the UE, as detailed in the configuration method in Example 2.

[0280] Example 3

[0281] Corresponding to scenario 2, the L1 measurement resource configuration for SCG LTM is configured via SN RRC messages.

[0282] Main invention content: Since it supports SCG LTM configured via SN RRC Reconfiguration and SCG LTM configured via MN RRCReconfiguration, and the L1 measurement resource configuration includes the LTM candidate identifier corresponding to the measurement resource RS configuration, the time and frequency information corresponding to the corresponding measurement resource RS can be determined through this LTM candidate identifier.

[0283] Therefore, for this scenario, it is necessary to clarify whether the LTM Candidate ID included in the L1 measurement resource configuration of the SCG LTM corresponds to the SCG LTM configured through the SN RRC Reconfiguration or the SCG LTM configured through the MN RRC Reconfiguration.

[0284] When the UE does not support simultaneous configuration, should the SCG LTM be configured via SN RRC Reconfiguration or via MN RRC Reconfiguration?

[0285] Optionally, if the SN LTM configuration stored by the UE contains any LTM Candidate Config, then the L1 measurement resource configuration contained therein is associated with the LTM Candidate Config in the SN LTM configuration.

[0286] Optionally, if the SN LTM configuration stored by the UE does not contain any LTM Candidate Config, then the SN L1 measurement resource configuration contained therein is associated with the Candidate Config in the LTM configuration of the MN configuration.

[0287] When a UE supports both SCG LTM configured with SN RRC Reconfiguration and SCG LTM configured with MN RRC Reconfiguration, it is necessary to indicate in the measurement resource configuration of the SCG LTM configured in the SN LTM configuration whether the LTM candidate information corresponding to the reference signal RS configuration is configured with MN or SN (i.e., MN format or SN format).

[0288] For example, as shown below, it can be determined based on the parameter ltm-CandidateFormat-r18-rxx.

[0289] For L1 reporting configuration, the L1 reporting configuration for SCG LTM is included in the serving cell configuration in the candidate configuration and in the current Source PSCell configuration. As described in Scenario 1, the L1 LTM measurement resource identifier (i.e., ltm-CSI-ResourceConfigId) associated in the L1 LTM reporting configuration in the PSCell and Candidate PSCell is the measurement resource identifier for the SN configured in the MN.

[0290] In summary, the examples disclosed above propose corresponding measurement resource configuration identifier negotiation methods, measurement resource configuration methods, and association methods between measurement resource configuration and LTM candidate information for two scenarios: L1 measurement corresponding to SCG LTM is configured by MN and L1 measurement corresponding to SCG LTM is configured by SN.

[0291] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0292] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed, which includes units or modules for implementing the steps performed by the terminal in any of the above methods.

[0293] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0294] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).

[0295] Figure 5A is a schematic diagram of the structure of a first network node according to an embodiment of this disclosure. The first network node 5100 is used to perform any of the above methods. In some embodiments, as shown in Figure 5A, the first network node 5100 may include a transceiver module 5101.

[0296] In some embodiments, the transceiver module is used to send first configuration identifier related information to the second network node, and / or send first configuration information and second configuration information to the terminal. The first configuration identifier is used to identify the first configuration information, the first configuration information is configuration information of measurement resources used for measurement, and the second configuration information is candidate configuration information of one or more mobility.
