[0115] Mobility Introduction

[0116] 1. Dynamic cell (or cell group) change

[0117] In 5G system, the network side can provide one or more candidate configurations for the terminal, wherein one candidate configuration can include one or more "cells (or cell groups)". The network side can subsequently control the terminal to change in multiple "candidate configurations" (such as changing the working cell (or cell group) from "cell (or cell group)-1" to "cell (or cell group)-2") through L1 signaling (such as downlink control information (DCI)) or L2 signaling (such as MAC control element (CE)). This control signaling can be referred to as "cell change control signaling".

[0118] This process can also be referred to as a network triggered LTM process.

[0119] LTM definition:

[0120] Rel-18 LTM refers to a process of network triggered PCell / PSCell cell change based on L1 measurement results through MAC CE, which can be accompanied by Master Cell Group (MCG) / Secondary Cell Group (SCG) change.

[0121] In Rel-18 LTM, the base station gNB receives the L1 measurement report from the UE, and based on this, the gNB changes the serving cell of the UE through the cell change command (cell switch command) issued by the MAC CE. The cell switch command indicates an LTM candidate cell configuration that the gNB has previously provided to the UE through radio resource control (RRC) signaling. The UE accesses the target cell indicated in the cell switch command according to the received cell switch command. LTM can be used to reduce mobility latency.

[0122] Among them, the LTM candidate cell configuration can only be added, modified and released by the network through RRC signaling. LTM process can be used to reduce mobility delay.

[0123] For LTM, Rel-18 LTM supports Subsequent LTM, where Subsequent LTM refers to subsequent LTM cell switch procedures between candidate cells without RRC reconfiguration by the network in between. That is, after performing a mobility operation, the UE does not autonomously delete the configuration information of the LTM, which can continue to be used even without RRC reconfiguration and update, for triggering Subsequent LTM.

[0124] LTM configuration:

[0125] In Rel-18, LTM is configured by LTM configuration (LTM-Config) to configure LTM configuration information.

[0126] Wherein, the LTM configuration information can contain but is not limited to one or more of the following information: LTM reference configuration; one or more candidate cell configurations (add / modify / remove list: such as LTM candidate cell removal list ltm-CandidateToReleaseList, LTM candidate cell addition list ltm-CandidateToAddModList, to add / modify / remove candidate cell configuration); LTM CSI resource configuration; etc.

[0127] Wherein, the candidate cell configuration can be configured by LTM candidate configuration (LTM-Candidate), which contains but is not limited to one or more of the following information: configuration identification; candidate cell identification; candidate configuration (represented by radio resource control reconfiguration RRCReconfiguration); etc.

[0128] LTM candidate configuration: (A configuration part of an RRCReconfiguration message associated with a candidate cell, e.g.,for LTM or subsequent CPAC.A candidate configuration can be a complete candidate configuration or a delta configuration relatively to a reference configuration.)

[0129] LTM reference configuration: (A configuration provided by the network to the UE that is common,within the same cell group,to a group of configured non-complete candidate configurations.)

[0130] L1 measurement for LTM

[0131] 1, Network (NW) triggered L1 measurement reporting.

[0132] In R18 LTM, 3GPP has enhanced L1 measurement, supporting intra-frequency and inter-frequency L1 measurement. Currently, R18 only supports Synchronization Signal and PBCH block (SSB) based L1-Reference Signal Received Power (L1-RSRP) measurement.

[0133] The existing L1 measurement supports semi-persistent and aperiodic reporting on the Physical Uplink Shared Channel (PUSCH) and semi-persistent and periodic reporting on the PUCCH.

[0134] In R19, there are many companies supporting the enhancement of L1 measurement, including the following aspects:

[0135] o Information State Information Reference Channel State Information Reference Signal CSI-RS measurement;

[0136] o Layer 1 Signal to Interference and Noise Ratio L1-SINR measurement;

[0137] o Event-triggered L1 measurement reporting;

[0138] o Current L1 measurement enhancement.

[0139] In the existing process, the cell switch command of LTM is generated by the source DU (Source gNB-DU), and in the intra-CU LTM, the Source gNB-DU makes the cell switch decision, and the Source gNB-DU makes the cell switch decision according to the L1 measurement result reported by the UE to determine the trigger LTM access candidate target cell, and then the Source gNB-DU sends the cell switch command to the UE. DU can be called gNB-DU and CU can be called gNB-CU.

[0140] 2, event-based L1 measurement reporting

[0141] In order to reduce measurement reporting and improve the robustness of mobility, event-triggered measurement reporting is supported in Rel-19, and event-triggered measurement reporting can assist the NW side to select the target beam and / or cell to trigger early synchronization, or assist the NW side to select the target cell and / or corresponding beam when triggering LTM cell switch.

[0142] When the L1 measurement result meets the following events, the measurement report can be triggered.

[0143] - Event LTM2 (Event LTM 2): The beam of the serving cell becomes worse than the threshold (Beam of serving cell becomes worse than absolute threshold);

[0144] - Event LTM3: Beam of candidate cell becomes amount of offset better than beam of serving cell;

[0145] - Event LTM4: Beam of candidate cell becomes better than absolute threshold;

[0146] - Event LTM5: Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0147] Where, the beam of serving cell is the current beam, i.e. the beam indicated by the indicated TCI state. The beam of candidate cell is any one or more beams configured in the candidate reference signal configuration (or measurement resource configuration).

[0148] Where, the event-based L1 measurement reporting is sent to the network through MAC CE message.

[0149] Where, the configuration of measurement event is in the serving cell configuration, and the configuration of measurement event is associated with the configuration of measurement resource.

[0150] 2: Conditionally triggered mobility procedure

[0151] In 5G system, the terminal can be based on the network "pre-configured condition", and the "pre-configured cell (or cell group)" corresponding to the condition. When the terminal meets the "pre-configured condition" (such as a specific measurement event), the terminal changes the serving cell (or cell group) to the "pre-configured cell (or cell group)".

[0152] The terminal can also change the configuration of a specific cell (or cell group) after meeting the "pre-configured condition" according to the network indication. (For example, change the PCell configuration of the terminal from candidate cell (or cell group) configuration-1 to candidate cell (or cell group) configuration-2).

[0153] Wherein, the mobility supports subsequent mobility, wherein the subsequent mobility includes any one of the mobility operations that the UE does not autonomously delete the mobility configuration information after performing the mobility operation. Wherein, the mobility configuration information includes the candidate configuration of the mobility.

[0154] In some cases, the configuration information of the mobility can continue to be used even without RRC reconfiguration and update, for triggering subsequent mobility.

[0155] Wherein, the "conditional trigger-based mobility procedure" includes:

[0156] Conditional trigger-based layer 3 (L3) mobility: conditional handover (CHO), conditional primary secondary cell (or cell group) addition (CPA), conditional primary secondary cell (or cell group) change (CPC), CHO with target secondary cell group (CHO with Candidate SCG(s)), CHO with target secondary cell group (CHO with target SCG).

[0157] The above-mentioned CHO, CPA, CPC and other mobility operations all support Subsequent Mobility, that is, support Subsequent CHO, Subsequent CPA, Subsequent CPC.

[0158] Conditional LTM (conditional trigger-based LTM).

[0159] Wherein, the conditional trigger-based LTM can be used for MCG change and SCG change, including:

[0160] Conditional LTM for MCG;

[0161] Conditional LTM for SCG;

[0162] And Conditional LTM for MCG and SCG.

[0163] Conditional LTM will be discussed in Rel-19 Mobility Enhancements study item.

[0164] The following is an introduction to several conditional trigger-based mobility that has already been supported:

[0165] CHO:

[0166] CHO refers to: when one or more handover execution conditions are met, the handover performed by the UE. The UE starts evaluating the execution conditions after receiving the CHO configuration and stops evaluating the execution conditions after performing the handover (including: legacy handover and CHO). CHO is suitable for the following criteria:

[0167] * CHO configuration includes CHO candidate cell configuration and execution conditions

[0168] * One execution condition may contain one or two trigger conditions (CHO events A3 / A5) [2].

[0169] Conditional Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0170] Conditional Event A5 (CondEvent A5): PCell / PSCell becomes worse than absolute threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold2;

[0171] * Before any CHO execution condition is met, the UE receives a HO (without CHO configuration) command, then performs the legacy HO procedure regardless of any CHO configuration previously received.

[0172] * When performing CHO, i.e. from the time the UE starts synchronizing with the target cell, the UE does not monitor the source cell.

[0173] CPA:

[0174] CPA refers to: UE performs PSCell addition when the execution condition is met. The UE starts to evaluate the execution condition when receiving the configuration of CPA, and stops evaluating the execution condition once the PCell addition or PCell change is triggered.

[0175] CPA is triggered by MN, and the execution condition of CPA is generated by MN, which corresponds to the measurement configuration associated with MCG.

[0176] CPC:

[0177] CPC refers to: UE performs PSCell change when the execution condition is met. The terminal starts to evaluate the execution condition after receiving the CPC configuration, and stops evaluating the execution condition once the PCell changes or triggers the PCell to change.

[0178] In the existing version, inter-SN CPC initiated by secondary node SN without the participation of master node MN is supported, and MN or SN initiated intra-SN CPC is supported.

[0179] CPA and CPC can be collectively referred to as CPAC, Conditional PSCell Addition or Change.

[0180] Subsequent CPAC Subsequent CPAC (Subsequent Conditional PSCell Addition or Change):

[0181] In Rel-18, considering Rel-16 conditional handover (CHO) and in Rel-17 conditional PSCell change (CPC) / conditional PSCell addition (CPA), the UE configured with CHO / CPC / CPA releases the CHO / CPC / CPA configuration when completing random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize CHO / CPC / CPA, the terminal has no opportunity to continue to perform CHO / CPC / CPA subsequently. This will increase the delay of handover or SCG change and increase the signal overhead, especially in the FR2 scenario, in the case of frequent changes of CG. Therefore, Rel-18 studies subsequent CHO / CPAC, due to time limit, currently Rel-18 only supports subsequent CPAC.

[0182] Subsequent CPAC is a conditional PSCell addition or change procedure performed based on the preconfigured subsequent CPAC configuration of the candidate PSCell after PSCell addition, PSCell change or SCG release, in which case there is no need to reconfigure and restart CPC / CPA.

[0183] For subsequent CPAC, the UE does not automatically delete the corresponding conditional reconfiguration configuration information after performing one or more of PSCell addition, PSCell change, SCG release, PCell change, etc. (which is different from the traditional legacy CPAC).

[0184] DU-CU architecture is an important architecture in modern wireless communication networks, especially in 5G networks. This architecture divides the functions of a base station into a distributed unit (DU) and a centralized unit (CU) to optimize the performance and flexibility of the network. Among them, the DU can be responsible for processing wireless signals, data forwarding, and direct communication with user equipment. The DU is generally located close to the edge of the user, close to the RU (Radio Unit), and mainly handles RLC, MAC and part of the PHY layer functions to reduce latency and improve signal quality. The CU can be responsible for processing high-level protocols such as RRC, PDCP, user session processing and data flow aggregation. The CU is usually located in a more central location and is responsible for processing data streams from multiple DUs.

[0185] The DU-CU architecture allows operators to flexibly increase or decrease the number of DUs and CUs as needed to cope with changing user demand and network traffic. The DU is close to the user, which can reduce the distance of signal transmission, thereby reducing communication delay and meeting real-time application requirements. The DU is responsible for real-time data processing and direct communication of wireless signals, allowing the CU to focus on processing higher-level network management, improving overall network performance. By separating DUs and CUs, network resources can be more effectively allocated and utilized to optimize user experience. The combination of distribution and centralization makes network management simpler, and operators can more easily monitor and maintain network performance.

[0186] It should be noted that the above-mentioned devices or names for processing part of the high-level protocol stack operations are not limited to centralized units CU, and other devices or devices with other names that have the function of processing part of the high-level protocol stack operations are also included in this application. The above-mentioned devices or names for processing low-level protocol stack related operations are not limited to distributed units DU, and other devices or devices with other names that have the function of processing low-level protocol stack related operations are also included in this application.

[0187] The mobility operation of the related technology can include: Layer 1 / Layer 2 triggered mobility (L1 / L2 Triggered Mobility, LTM) and conditionally triggered mobility; wherein the LTM is a mobility operation triggered by the network device based on Layer 1 / Layer 2; the conditionally triggered mobility can include mobility based on Layer 3 measurement results and mobility based on Layer 1 / Layer 2 measurement results.

[0188] Wherein, Layer 1 (Layer 1, L1) can be a physical layer; Layer 2 (Layer 2, L2) can be any one or more of Medium Access Control (MAC) layer, Radio Link Control (RLC) layer, and Packet Data Convergence Protocol (PDCP) layer; Layer 3 (Layer 3, L3) can be a Radio Resource Control (RRC) layer.

[0189] Wherein, the mobility based on Layer 3 measurement results can include any one or more of conditional handover (CHO), conditional PSCell change (CPC), conditional PSCell addition (CPA), CHO with target SCG, and CHO with Candidate SCG(s).

[0190] Wherein, the mobility based on Layer 1 / Layer 2 measurement results can include conditional LTM (Conditional LTM).

[0191] In some embodiments, the conditional LTM corresponds to a mobility procedure in which any one or more of early uplink and / or downlink synchronization, subsequent LTM, early activation of Transmission Configuration Indicator state (TCI state), and the like can be implemented. In some embodiments, the conditional LTM can also be a mobility based on a layer 3 measurement result. Unlike certain L3 mobility based on a layer 3 measurement result, the conditional LTM corresponds to a mobility procedure in which any one or more of early uplink and / or downlink synchronization, subsequent LTM, early activation of Transmission Configuration Indicator state (TCI state), and the like can be implemented.

[0192] In some embodiments, the mobility based on a layer 3 measurement result and / or the mobility based on a layer 1 / layer 2 measurement result can be referred to as a mobility based on a conditional trigger, or a conditional mobility, and the like, without limitation.

[0193] For example, the conditional LTM can also be referred to as a mobility based on a conditional trigger, or a conditional mobility.

[0194] In a dual connectivity (DC) architecture, the LTM can be implemented by a distribution unit (DU) based on a measurement result of an L1 beam reported by a UE. In order to implement fast switching, the influence of the LTM measurement result on a switching decision needs to be considered. Currently, an event based on the LTM measurement result is supported. The execution condition of the conditional LTM should be associated with the LTM measurement result, that is, associated with an LTM measurement event.

[0195] It has been determined that the configuration of the LTM measurement event will be generated by the DU. However, the execution condition of the LTM needs to be associated with the LTM candidate configuration and included in the LTM configuration, which is generated by a central unit (CU). Therefore, in order to support the configuration of the conditional LTM, a configuration method is proposed to determine the interaction between the CU and the DU for the LTM execution condition.

[0196] In addition, for the mobility based on a layer 1 / layer 2 measurement result, the execution condition can also be associated with any one or more of an event corresponding to a layer 1 (L1) measurement, a layer 2 (L2) measurement, a Channel State Information (CSI) measurement, an LTM measurement, an LTM CSI measurement, a layer 1 LTM measurement, and a layer 2 LTM measurement.

[0197] The layer 1 / layer 2 measurement configuration (for example, configuration of any one or more of: layer 1 (L1) measurement; layer 2 (L2) measurement; channel state information (CSI) measurement; LTM measurement; LTM CSI measurement; layer 1 LTM measurement; layer 2 LTM measurement) will be generated by the DU, but the execution condition of the mobility based on the condition of the layer 1 / layer 2 measurement result needs to be associated with the configuration of the mobility based on the condition of the layer 1 / layer 2 measurement result and contained in the mobility configuration, and the mobility configuration is generated by the CU, so in order to support the configuration of the mobility based on the condition of the layer 1 / layer 2 measurement result, the present application proposes a configuration method to determine the method of interaction of the mobility execution condition between the CU and the DU. FIG. 2A is an interaction schematic diagram of a configuration method of a mobility operation according to an embodiment of the present disclosure.

[0198] As shown in FIG. 2A, the configuration method of the mobility operation includes:

[0199] In step S201, the first communication device sends first information to the second communication device.

[0200] In some embodiments, the first communication device can send the first information to the second communication device, wherein the first information can be used to provide the second communication device with relevant information for determining the execution condition, so that the second communication device can generate second information containing the execution condition based on the first information.

[0201] Wherein, the first communication device can be a centralized unit (CU) under a dual connectivity (DC) architecture, which can be a CU of a serving node or a CU of a candidate node; the second communication device can be a distributed unit (DU), which can be a DU of a serving node or a DU of a candidate node. Wherein, the CU of the serving node is the CU of the node where the current serving cell is located, which can also be called the source CU; the CU of the candidate node is the CU of the node where the candidate cell is located; the DU of the serving node is the DU of the node where the current serving cell is located, which can also be called the source DU; the DU of the candidate node is the DU of the node where the candidate cell is located, which can also be called the candidate DU or the target DU.

[0202] Wherein, the execution condition can be an execution condition of a mobility operation triggered based on a condition.

[0203] Wherein, the mobility operation can include: mobility triggered based on layer 1 / layer 2 measurement, and / or mobility based on a condition;

[0204] The mobility based on layer 1 / layer 2 measurement triggering can include mobility triggered based on one or more of the following measurements: L1 measurement; L2 measurement; Channel State Information (CSI) measurement; layer 1 / layer 2 triggered mobility (LTM) measurement; LTM CSI measurement; L1 LTM measurement; L2 LTM measurement; physical layer measurement; medium access control (MAC) layer measurement.

[0205] The mobility based on conditional triggering can include any one or more of the following mobility: conditional LTM (Conditional LTM), CHO, CPC, CPA, CHO with Candidate SCG(s), CHO with target SCG, and the like.

[0206] The conditional LTM can include any one or more of the following: conditional LTM for a master cell group (MCG) or a primary cell (PCell); conditional LTM for a secondary cell group (SCG) or a primary secondary cell (PSCell); conditional LTM for the MCG (PCell) and the SCG (PSCell).

[0207] In some embodiments, the first information can include at least one of the following:

[0208] A first identifier, the first identifier being used to indicate the first candidate cell, for example, a cell identifier (Cell ID), which can also be referred to as a first candidate cell ID;

[0209] A second identifier, the second identifier being used to indicate a first candidate configuration, the first candidate configuration being a candidate configuration of the first candidate cell; for example, a configuration ID, which can also be referred to as a conditional mobility (Conditional Mobility) candidate configuration ID;

[0210] A first information table, the first information table being used to indicate a correspondence between a candidate cell identifier and a candidate configuration identifier; for example, a conditional mobility (Conditional Mobility) configuration identifier mapping list (Configuration ID Mapping List);

[0211] An example is that one candidate cell identifier corresponds to one candidate configuration identifier.

[0212] For example, the candidate cells indicated in the first information table may include the first candidate cell indicated by the first identifier, such as all candidate cells prepared by the network side for the terminal, or may not include the candidate cells indicated by the first identifier, such as other candidate cells prepared by the network side for the terminal besides the first candidate cell.

[0213] The relevant measurement configuration used to trigger the first mobility operation;

[0214] The fourth configuration information, the third configuration information being used to indicate the recommended configuration for the execution conditions, such as the CU-recommended Conditional Mobility execution condition configuration parameters;

[0215] Information related to subsequent mobility operations, such as information related to subsequent conditional mobility.

[0216] For example, subsequent conditional mobility can be referred to as any one or more of the names such as subsequent / following, following / after, next / next, continuous / continuous conditional mobility, and the corresponding to subsequent / following, following / after, next / next, continuous / continuous can correspond to Subsequent.

[0217] The second identifier may include any one or more of the following identifiers: candidate configuration identifier; LTM candidate identifier; candidate cell identifier corresponding to mobility configuration; conditional reconfiguration identifier.

[0218] The first information table may include at least one of the following: a first identifier; a second identifier corresponding to the first identifier; a third identifier, which is used to indicate a second candidate cell, such as a second candidate cell ID; and a fourth identifier corresponding to the third identifier, which is used to indicate a second candidate configuration, which is a candidate configuration for the second candidate cell.

[0219] The second candidate cell can be a candidate cell that can be used for subsequent mobility operations (second mobility operations) after the first mobility operation is triggered for the first candidate cell and access is made to the first candidate cell.

[0220] For example, subsequent mobility can be referred to as any one or more of the names such as subsequent / following, following / after, next / next, continuous / continuous mobility, etc., and corresponding to subsequent / following, following / after, next / next, continuous / continuous can correspond to Subsequent.

[0221] The second execution condition associated with the second candidate cell can be an execution condition required to be evaluated for triggering the second mobility operation, which can also be referred to as a subsequent mobility execution condition.

[0222] For example, the subsequent mobility (subsequent conditional mobility) includes any one of the mobility operations in which the UE does not autonomously delete the mobility configuration information after the mobility operation is performed. The mobility configuration information includes the candidate configuration of the mobility.

[0223] For example, the mobility configuration information can continue to be used even without reconfiguration and update for triggering the subsequent mobility procedure. For LTM, a subsequent LTM (Subsequent LTM) can be supported, in which the Subsequent LTM refers to a subsequent LTM cell switching procedure between candidate cells without RRC reconfiguration by the network in between. That is, the UE does not autonomously delete the LTM configuration information after the mobility operation is performed, and the LTM configuration information can continue to be used even without RRC reconfiguration and update for triggering the subsequent LTM.

[0224] The RRC reconfiguration by the network in between refers to that the network side does not reconfigure the LTM candidate configuration through an RRC reconfiguration message.

[0225] Correspondingly, in some embodiments, for the conditional mobility, a subsequent mobility (subsequent conditional mobility) can be supported, in which the subsequent conditional mobility refers to a subsequent mobility procedure between candidate cells without RRC reconfiguration by the network in between. That is, the UE does not autonomously delete the conditional mobility configuration information after the mobility operation is performed, and the subsequent conditional mobility configuration information can continue to be used even without RRC reconfiguration and update for triggering the subsequent mobility procedure. For example, for the conditional trigger-based mobility operation, a subsequent mobility can also be supported, for example, for the Conditional LTM, a subsequent conditional LTM (Subsequent Conditional LTM) can also be supported, in which the subsequent mobility includes any one of the mobility operations in which the UE does not autonomously delete the mobility configuration information after the mobility operation is performed. The mobility configuration information includes the candidate configuration of the mobility.

[0226] The mobility configuration information can continue to be used even without RRC reconfiguration and update for triggering the subsequent mobility.

[0227] For example, the intermediate does not need the network to perform RRC reconfiguration means that the network side does not need to reconfigure the candidate configuration of the conditional mobility through the RRC reconfiguration message

[0228] In some embodiments, the first information table can include all or part of the candidate cells that the terminal has been configured or is ready to be configured, for example, all conditional mobility candidate cells, or other conditional mobility candidate cells in addition to the first candidate cell.

[0229] In some embodiments, the first information table can include a set of second candidate cell IDs corresponding to the first candidate cell, and the associated candidate configuration IDs.

[0230] For example, Table 1 below is an LTM configuration identification mapping information table LTM Configuration ID Mapping List:

[0231] Table 1

[0232] As shown in the above table, the LTM configuration identification mapping information table indicates the mapping relationship between the candidate cell identification LTM Cell ID and the candidate configuration identification LTM Configuration ID.

[0233] In some embodiments, the first information includes fourth configuration information associated with each first candidate cell and / or first candidate configuration respectively.

[0234] Each fourth configuration information includes at least one of the following: a first identification for indicating the first candidate cell; a second identification for indicating the first candidate configuration, and a recommended configuration of the first execution condition associated with the first identification and / or the second identification.

[0235] In the recommended configuration of each first execution condition, a set of first events associated with the first execution condition is recommended.

[0236] For example, Table 2 shows a fourth configuration information:

[0237] Table 2

[0238] In Table 2, the execution condition configuration parameter corresponding to each Cell ID and configuration ID includes a set of event recommendation configuration associated with the execution condition, for example: the execution condition configuration parameter 1 includes the parameters of the execution condition 1 associated with the Cell ID 1 and the configuration ID 1, including the parameters of the event A and the event B associated with the execution condition 1; the execution condition configuration parameter 2 includes the parameters of the execution condition 2 associated with the Cell ID 2 and the configuration ID 2, including the parameters of the event C and the event D associated with the execution condition 2; the execution condition configuration parameter 3 includes the parameters of the execution condition 3 associated with the Cell ID 3 and the configuration ID 3, including the parameters of the event E and the event F associated with the execution condition 3. It can be seen that the execution condition 1 is the first execution condition associated with the first candidate cell indicated by the Cell ID 1 and the first candidate configuration indicated by the configuration ID 1, and the event A and the event B are the first events associated with the execution condition 1; the execution condition 2 is the first execution condition associated with the first candidate cell indicated by the Cell ID 2 and the first candidate configuration indicated by the configuration ID 2, and the event C and the event D are the first events associated with the execution condition 2; the execution condition 3 is the first execution condition associated with the first candidate cell indicated by the Cell ID 3 and the first candidate configuration indicated by the configuration ID 3, and the event E and the event F are the first events associated with the execution condition 3.

[0239] In some embodiments, the first event can include at least one of the following event types:

[0240] The first measurement result of the serving cell is lower than the first threshold value, and the first measurement result is a beam measurement result, for example, event LTM2 (EventLTM2), conditional event LTM2 (CondEventLTM2): the beam of the serving cell becomes worse than the threshold value (Beam of serving cell becomes worse than absolute threshold);

[0241] The first measurement result of the candidate cell is better than the first measurement result of the serving cell, and the difference reaches the first offset amount, for example, event LTM3 (EventLTM3), conditional event LTM3 (CondEventLTM3): the beam of the candidate cell is better than the beam of the serving cell by an offset amount (Beam of candidate cell becomes amount of offset better than beam of serving cell);

[0242] a first measurement result of the candidate cell is above a second threshold value, e.g. Event LTM4 (EventLTM4), Condition Event LTM4 (CondEventLTM4): Beam of candidate cell becomes better than absolute threshold;

[0243] a first measurement result of the serving cell is below a third threshold value and a first measurement result of the candidate cell is above a fourth threshold value; e.g. Event LTM5 (EventLTM5), Condition Event LTM5 (CondEventLTM5): Beam of serving cell becomes worse than absolute threshold1 AND Beam of candidate cell becomes better than another absolute threshold2.

[0244] a second measurement result of the serving cell is below a fifth threshold value, the second measurement result being a cell level measurement result;

[0245] a second measurement result of the candidate cell is better than the second measurement result of the serving cell by a second offset, e.g. Condition Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes amount of offset better than PCell / PSCell;

[0246] a second measurement result of the candidate cell is higher than a sixth threshold value, e.g., Conditional Event A3 (CondEvent A3): Conditional reconfiguration candidate becomes better than absolute threshold, where condEventA3 can also be used for current PSCell (i.e., in case it is configured as candidate PSCell for CondEvent A3 evaluation) for CHO with candidate SCG(s) case;

[0247] a second measurement result of the serving cell is lower than a seventh threshold value, and a second measurement result of the candidate cell is higher than an eighth threshold value, e.g., Conditional Event A5 (CondEvent A5): PCell / PSCell becomes worse than absolute threshold threshold1 AND Conditional reconfiguration candidate becomes better than another absolute threshold threshold2;

[0248] a distance between the terminal and a first reference location of the serving cell is greater than a ninth threshold value and a distance between the terminal and a second reference location of the candidate cell is smaller than a tenth threshold value, e.g., a conditional event D1 (CondEvent D1): a distance between the terminal and a reference location referenceLocation1 becomes larger than a configured threshold distanceThreshFromReference1 and a distance between the terminal and a reference location referenceLocation2 of a conditional reconfiguration candidate becomes shorter than a configured threshold distanceThreshFromReference2 (Distance between UE and a reference location referenceLocation1 becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a reference location referenceLocation2 of conditional reconfiguration candidate becomes shorter than configured threshold distanceThreshFromReference2);

[0249] a distance between the terminal and a first moving reference location of the serving cell is greater than an eleventh threshold value and a distance between the terminal and a second moving reference location of the candidate cell is smaller than a twelfth threshold value, e.g., a conditional event D2 (CondEvent D2): a distance between the terminal and a moving reference location of the serving cell determined based on movingReferenceLocation and its corresponding satellite ephemeris and epoch time broadcast in SIB19 becomes larger than a configured threshold distanceThreshFromReference1 and a distance between the terminal and a moving reference location of the serving cell determined based on referenceLocation and its corresponding satellite ephemeris and epoch time for the conditional reconfiguration candidate provided in the associated MeasObjectNR becomes shorter than a configured threshold distanceThreshFromReference2 (Distance between UE and the serving cell moving reference location determined based on movingReferenceLocation and its corresponding satellite ephemeris and epoch time broadcast in SIB19 becomes larger than configured threshold distanceThreshFromReference1 and distance between UE and a moving reference location determined based on referenceLocation and its corresponding satellite ephemeris and epoch time for the conditional reconfiguration candidate provided in the associated MeasObjectNR becomes shorter than configured threshold distanceThreshFromReference2);

[0250] The measurement duration of the terminal obtaining the second measurement result is greater than a thirteenth threshold value and less than a fourteenth threshold value, for example, a conditional event T1 (CondEvent T1): the time measured at the terminal is greater than the configured threshold t1-Threshold but is less than t1-Threshold+duration (Time measured at UE becomes more than configured threshold t1-Threshold but is less than t1-Threshold+duration);

[0251] In some embodiments, the recommendation configuration for the first event can include at least one of the following:

[0252] Measurement reference signal;

[0253] Measurement resource configuration;

[0254] Identification of measurement resource;

[0255] Threshold value for evaluating the first event, for example, threshold value of Event LTM2~5 and / or CondEvent LTM2~5;

[0256] Offset;

[0257] Trigger time;

[0258] Hysteresis value.

[0259] The offset can be: cell level offset, beam level offset, and frequency level offset.

[0260] In step S202, the second communication device sends second information to the first communication device.

[0261] In some embodiments, after receiving the first information, the second communication device can generate the second information based on the first information, the second information being used to indicate an execution condition to be evaluated, the execution condition to be evaluated being used to trigger the first mobility operation, and the second information can be an execution condition configuration of the conditional mobility, for example, an execution condition configuration of the conditional mobility.

[0262] The first mobility operation can include a conditional triggered mobility operation.

[0263] The second communication device can send the generated second information to the first communication device.

[0264] For example, the DU determines a corresponding configuration of an event for the Conditional Mobility based on the first information including the recommended Conditional Mobility, performs a configuration identification corresponding to one or more events associated with the Conditional Mobility, and transmits the above information to the CU through the second information.

[0265] In some embodiments, after receiving the second information from the second communication device, the first communication device can determine an execution condition required for evaluating a trigger of the first mobility operation based on the second information, and generate the first configuration information, so as to configure the first mobility operation for the terminal by transmitting the first configuration information to the terminal.

The second configuration information can include the first candidate configuration and / or the first candidate cell, and the first execution condition associated therewith.

[0267] The first candidate configuration and / or the first candidate cell included in the second configuration information can be represented by a first candidate configuration identifier and / or a first candidate cell identifier.

[0268] In some embodiments, the second information can include second configuration information, and the second configuration information can be used to indicate the first execution condition, the first execution condition being an execution condition associated with a first candidate DU corresponding to the first mobility operation.

[0269] The second configuration information can include the first candidate DU and the first execution condition associated therewith. The first candidate DU can be represented by a first candidate DU identifier.

[0270] In some embodiments, the second configuration information can include any one or more of a CU identifier, a candidate DU identifier, a current DU identifier, a second communication device identifier, a first communication device identifier, a first identifier, a second identifier, and a corresponding first execution condition.

[0271] In some embodiments, the second configuration information can exist in the form of a list. The second information can include a first list, and the first list includes at least one set of second configuration information, the second configuration information including at least one of the following: a first identifier and / or a second identifier, and a corresponding first execution condition, wherein the first identifier is used to indicate the first candidate cell, and the second identifier is used to indicate the first candidate configuration.

[0272] In some embodiments, the second configuration information comprises any one or more of the following: a CU identifier, a candidate DU identifier, a current DU identifier, a second communication device identifier, a first communication device identifier, a first identifier, a second identifier, and a corresponding first execution condition, wherein the first identifier is used to indicate the first candidate cell, and the second identifier is used to indicate the first candidate configuration.

[0273] In some embodiments, the second information can comprise a Conditional Mobility execution condition information table (first list), and the execution condition configuration of Conditional Mobility is transmitted through the Conditional Mobility execution condition information table.

[0274] As shown in Table 3 below, the Conditional Mobility execution condition information table can comprise multiple sets of execution condition configuration information: execution condition configuration information set 1-3, each set of execution condition configuration information comprising an identifier and / or configuration identifier of a candidate cell and an execution condition configuration.

[0275] Table 3

[0276] In some embodiments, the first execution condition configuration can be transmitted by associating and / or containing the execution condition configuration defined in the RRC protocol. For example, for CHO / CPAC, it can be determined by containing CondExecutionCond or CondExecutionCondPSCell. Or for Conditional LTM, it can be determined by containing the corresponding parameters of the execution condition configuration of the Conditional LTM.

[0277] In some embodiments, the first execution condition is associated with one or more first events.

[0278] In some embodiments, the first execution condition is associated with one or more first events.

[0279] In some embodiments, the first execution condition can comprise a configuration of the first event.

[0280] In some embodiments, the third identification can be indicated as the first event associated with the first execution condition by including the third identification in the first execution condition.

[0281] The third identification can include any one or more of the following identifications: measurement identification; reporting configuration identification; LTM CSI reporting configuration identification ltm-CSI-ReportConfigId; event identification.

[0282] In some embodiments, for mobility configuration, such as Conditional LTM, the first execution condition configuration contained therein can be associated with one or more LTM event corresponding configuration identification (e.g., LTM reporting configuration identification ltm-CSI-ReportConfigId).

[0283] For example, for CHO / CPAC, the first execution condition configuration can be associated with one or more first event corresponding configuration identification MeasId.

[0284] In some embodiments, the first communication device can generate first configuration information, such as Conditional Mobility configuration, based on the second information and send it to the UE, and the UE performs evaluation and triggering of Conditional Mobility based on the Conditional Mobility configuration.

[0285] In some embodiments, the second communication device can be a source DU, or a candidate DU or a target DU

[0286] In some embodiments, the first communication device can be a source CU, or a candidate CU or a target CU

[0287]

[0288] In some embodiments, in order to support subsequent mobility, such as Subsequent Conditional Mobility, the second execution condition for subsequent mobility needs to be generated by the target DU / candidate DU (where the target DU / candidate DU and the source DU can be the same or different), and then sent to the CU by the target DU / candidate DU, and the CU generates the first configuration information containing the initial first execution condition and the second execution condition, and sends it to the terminal.

[0289] In some embodiments, the second information sent by the second communication device to the first communication device can include third configuration information, the third configuration information being used to indicate a second execution condition, i.e., a second execution condition configuration, the second execution condition being an execution condition associated with a second candidate configuration and / or an execution condition associated with a second candidate cell, the second candidate configuration being a candidate configuration of the second candidate cell, the second execution condition being an execution condition needed to be evaluated to trigger a mobility operation for the second candidate cell after triggering a first mobility operation to access the first candidate cell.

[0290] In some embodiments, after receiving the first information, the second communication device can send second information to the first communication device, the second information including second configuration information, or including third configuration information, or including both the second configuration information and the third configuration information.

[0291] In some embodiments, the target DU / candidate DU can generate execution condition configurations for subsequent mobility for each first candidate cell, i.e., third configuration information or second execution condition configurations corresponding to each first candidate cell.

[0292] The candidate DU / target DU can generate a second execution condition information table for each first candidate cell, for example, as shown in Tables 4-6 below, Table 4 is a second execution condition information table configured with the first candidate cell ID1; Table 5 is a second execution condition information table configured with the first candidate cell ID2; and Table 6 is a second execution condition information table configured with the first candidate cell ID3:

[0293] Table 4

[0294] Table 5

[0295] Table 6

[0296] In some embodiments, the above-mentioned second execution condition configuration can be transmitted by being associated / contained in an execution condition defined in the RRC protocol. For example, for CHO / CPAC, it can be determined by containing a subsequent condition reconfiguration SubsequentCondReconfig. For example, for conditional LTM or LTM, it can be determined by containing parameters corresponding to the execution condition corresponding to the subsequent LTM.

[0297] The second execution condition configuration can be used to indicate one or more second events associated with the second execution condition, wherein the second events can have the same event type as the first events (e.g., RRM measurement events CondEventA3, CondEventA4, CondEventA5; LTM events CondEventLTM2, CondEventLTM3, CondEventLTM4, CondEventLTM5, EventLTM2, EventLTM3, EventLTM4, EventLTM5).

[0298] The manner of indicating the second execution condition can include that the second execution condition can be achieved by associating and / or including one or more second events.

[0299] In some embodiments, for mobility configurations such as Conditional LTM, the second execution condition configuration can be associated with configuration identifiers corresponding to one or more LTM events (e.g., LTM reporting configuration identifiers ltm-CSI-ReportConfigId).

[0300] For example, for CHO / CPAC, the second execution condition configuration can be associated with configuration identifiers MeasId corresponding to one or more second events.

[0301] In addition, in addition to the second execution condition information table described above, the candidate DU also needs to generate the measurement configuration of the event corresponding thereto and send it to the CU.

[0302] In some embodiments, if the second communication device is a DU of a serving node, the first information is carried by a third message, and the third message is used to send a mobility configuration to the DU of the serving node.

[0303] Before sending the first information to the second communication device, the first communication device can also send the first message to the DU of the candidate node, and the first message is used to initiate a mobility configuration request to the DU of the candidate node.

[0304] The second message is received from the DU of the candidate node, and the second message is used to indicate a mobility configuration related to the DU of the candidate node.

[0305] In some embodiments, the first message carries the first information sent to the DU of the candidate node; and the second message carries third configuration information related to the DU of the candidate node.

[0306] In some embodiments, the second information is carried by a fourth message, and after sending the second information to the second communication device, the first communication device can also send a fifth message to the DU of the candidate node, and the fifth message is used to initiate a mobility update request.

[0307] receiving a sixth message from the candidate node, the sixth message being used for indicating an updated mobility configuration related to the candidate node, the sixth message carrying updated third configuration information related to the candidate node.

[0308] In some embodiments, the second communication device is a DU of a candidate node, the first information is carried by a first message, the first message being used for initiating a mobility configuration request to the DU of the candidate node; the second information is carried by a second message, the second information including third configuration information related to the DU of the candidate node.

[0309] In some embodiments, after receiving the second information from the second communication device, the first communication device can further send a third message to the DU of the serving node, the third message carrying the first information; receive a fourth message from the DU of the serving node, the fourth message carrying the second information.

[0310] In some embodiments, after receiving the fourth message from the DU of the serving node, the first communication device can further send a fifth message to the second communication device, the fifth message being used for initiating a mobility update request; receive a sixth message from the second communication device, the sixth message being used for indicating an updated mobility configuration related to the second communication device, the sixth message carrying updated third configuration information related to the second communication device.

[0311] In some embodiments, the method for configuring mobility operation provided by the embodiments of the present application is as follows:

[0312] 1. The CU sends first information to the DU, the first information including but not limited to any one or more of the following information:

[0313] 1.1. A first candidate cell ID;

[0314] 1.2. A conditional mobility Conditional Mobility candidate configuration ID associated with the first candidate cell ID;

[0315] 1.3. A conditional mobility Conditional Mobility configuration identification matching information table;

[0316] 1.3.1. The conditional mobility Conditional Mobility configuration identification matching information table indicates all or part of the conditional mobility Conditional Mobility candidate cells that the UE has been configured or is ready to be configured;

[0317] 1.3.1.1. For example, all Conditional Mobility candidate cells, or other Conditional Mobility candidate cells except the first candidate cell;

[0318] 1.3.2 The Conditional Mobility configuration identifies the matching information table containing a set of second candidate cell IDs and their associated Conditional Mobility candidate configuration IDs;

[0319] 1.4. Measurement configuration and other information;

[0320] 1.5. Conditional Mobility execution condition configuration parameters recommended by the CU;

[0321] 1.6. Information related to Subsequent Conditional Mobility.

[0322] 2. Wherein the Conditional Mobility execution condition configuration parameters recommended by the CU in 1.5 contain execution condition configuration parameters recommended by the CU for each candidate cell / candidate configuration.

[0323] 2.1. The execution condition configuration parameters contain one or more sets of event configuration parameters for Conditional Mobility, which contain but are not limited to any one or more of the following information:

[0324] 2.1.1. Measurement reference signal;

[0325] 2.1.2. Measurement resource configuration / measurement resource ID;

[0326] 2.1.3. Threshold value for event evaluation, such as threshold value for Event LTM2~5 / CondEvent LTM2~5;

[0327] 2.1.4. Offset value for Cell / Beam / Frequency level;

[0328] 2.1.5. Trigger time;

[0329] 2.1.6. Hysteresis value.

[0330] 3. Based on 1, the DU generates the execution condition corresponding to the candidate cell / candidate configuration based on the first information and sends it to the CU through the second information.

[0331] 3.1. Exemplarily, for the information described in 1.5, the DU determines the corresponding configuration of the event for the Conditional Mobility based on the first information containing the recommended Conditional Mobility execution condition, and performs the configuration corresponding to one or more events associated with the Conditional Mobility execution condition, and sends the above information to the CU through the second information.

[0332] 4. Based on any one of 1-3, the DU sends the second information to the CU, and the second information is the execution condition configuration of the Conditional Mobility, wherein the second information contains the execution condition associated with the candidate configuration / candidate cell of the Conditional Mobility.

[0333] 4.1. The second information can contain the Conditional Mobility execution condition information table, and the execution condition configuration of the Conditional Mobility is transmitted through the Conditional Mobility execution condition information table.

[0334] 4.1.1. The Conditional Mobility execution condition information table can contain multiple sets of execution condition configuration information, and each set of execution condition configuration information contains the identification and / or configuration identification of the candidate cell and the execution condition configuration.

[0335] For example:

[0336] 4.2. Exemplarily, the execution condition configuration can be transmitted by associating / containing the execution condition configuration defined in the RRC protocol.

[0337] 4.2.1. For example, for CHO / CPAC, it can be determined by containing CondExecutionCond or CondExecutionCondPSCell.

[0338] 4.3 Exemplarily, the execution condition configuration can be implemented by associating / containing one or more events for the Conditional Mobility (such as RRM measurement events CondEventA3-A5; LTM events CondEvent LTM2-5, Event LTM2-5).

[0339] 4.3.1.1. For example, for Conditional LTM, the execution condition configuration is associated with one or more LTM event corresponding configuration identity (e.g. LTM reporting configuration identity, ltm-CSI-ReportConfigId).

[0340] 4.3.1.2. For example, for CHO / CPAC, the execution condition configuration is associated with one or more event corresponding configuration identity MeasId.

[0341] 5. Based on 1-4, the CU generates the Conditional Mobility configuration based on the second information and sends it to the UE, the UE performs the evaluation and triggering of the Conditional Mobility based on the Conditional Mobility configuration.

[0342] The DU in 1-5 can be a source DU or a target DU.

[0343] 6. To support the subsequent Conditional Mobility, the execution condition of the subsequent Conditional Mobility needs to be generated by the target DU / candidate DU (the target DU / candidate DU and the source DU can be the same or different), and then sent to the CU by the target DU / candidate DU, and the CU generates the Conditional Mobility configuration containing the initial Conditional Mobility execution condition and the subsequent Conditional Mobility execution condition, and sends it to the UE.

[0344] 6.1. The target DU / candidate DU generates the execution condition configuration of the subsequent Conditional Mobility for each of the first candidate cells of each of the Conditional Mobility.

[0345] 6.2. The execution condition of the Subsequent Conditional Mobility refers to that after the UE applies the candidate configuration of the current first candidate cell to access the corresponding first candidate cell, the UE evaluates the execution condition of other second candidate cells. The execution condition is related to both the current serving cell and the target cell, so the execution condition of the Subsequent Conditional LTM should be determined by the candidate DU where the first candidate cell is located, and is associated with the corresponding second candidate cell. Among them, the second candidate cell is part or all of the candidate cells configured by the network for the UE, except the first candidate cell.

[0346] For example, the candidate DU / target DU generates an execution condition information table of the Subsequent Conditional Mobility for each first candidate cell: as shown in Tables 4-6 above.

[0347] For example, the above-mentioned Subsequent execution condition configuration can be transmitted by being associated / contained in the execution condition configuration defined in the RRC protocol.

[0348] For example, for CHO / CPAC, it can be determined by containing SubsequentCondReconfig.

[0349] For example, the execution condition configuration can be implemented by associating / containing a group of Subsequent conditions, wherein each condition corresponds to a configuration ID of a Conditional Mobility and one or more events (such as RRM measurement events CondEventA3-A5; LTM events CondEvent LTM2-5, Event LTM2-5) for the Conditional Mobility.

[0350] For example, for Conditional LTM, the execution condition configuration is associated with the configuration identifier (such as LTM reporting configuration identifier, ltm-CSI-ReportConfigId) corresponding to one or more LTM events.

[0351] For example, for CHO / CPAC, the execution condition configuration is associated with the configuration identifier MeasId corresponding to one or more events.

[0352] In addition, in addition to the above-mentioned execution condition information table of the Subsequent Conditional Mobility, the candidate DU also needs to generate the measurement configuration of the corresponding event and send it to the CU.

[0353] Figure 2B illustrates a configuration method of mobility operation.

[0354] It should be noted that the first message, the third message, the fifth message in Figure 2B can be F1 messages such as UE CONTEXT SETUP REQUEST and / or UE CONTEXT MODIFICATION REQUEST; the second message, the fourth message, the sixth message can be F1 messages such as UE CONTEXT SETUP RESPONSE and / or UE CONTEXT MODIFICATION RESPONSE.

[0355] Wherein the mobility operation contains any one or more of the following three cases:

[0356] Case 1: If the subsequent conditional mobility Subsequent Conditional Mobility is not supported, the CU only needs to negotiate the execution condition of the initial conditional mobility Conditional Mobility with the source DU

[0357] Case 2: If the subsequent conditional mobility Subsequent Conditional Mobility is supported, the CU needs to negotiate the execution condition of the initial conditional mobility Conditional Mobility with the source DU, and the CU also needs to negotiate the execution condition of the subsequent conditional mobility Subsequent Conditional Mobility with the candidate DU, (initiate the negotiation process of the execution condition of the subsequent conditional mobility Subsequent Conditional Mobility after the CU determines which mobility request of the first candidate cell is accepted)

[0358] Case 3: If the subsequent conditional mobility Subsequent Conditional Mobility is supported, the CU needs to negotiate the execution condition of the initial conditional mobility Conditional Mobility with the source DU, and the CU also needs to negotiate the execution condition of the subsequent conditional mobility Subsequent Conditional Mobility with the candidate DU, (preparing the execution condition of the subsequent conditional mobility Subsequent Conditional Mobility through the first message and the second message, and then adjusting through the fifth message and the sixth message) then

[0359] For case 1, if subsequent conditional mobility is not supported, the CU only needs to negotiate with the source DU the execution condition of the initial conditional mobility, including the following steps:

[0360] 1.1 S1-2, the CU determines the candidate cell (first candidate cell) for which the conditional mobility needs to be configured based on the measurement report;

[0361] 1.2 S3-4, the CU sends a first message to the candidate DU where the first candidate cell is located to initiate a mobility configuration request process and request the candidate DU to prepare resources and corresponding configurations for the first candidate cell. The candidate DU accepts the request of the CU and sends corresponding configurations through a second message;

[0362] 1.2.1 In some embodiments, the CU needs to send a first message for each first candidate cell on the candidate DU.

[0363] 1.2.2 It should be noted that the first message and the second message in the above process do not need to contain the first information and the second information.

[0364] 1.3 S5, the CU sends a third message to the source DU, which includes the accepted target candidate cell and the corresponding configuration identifier, in this case, the third message can contain the first information. Step 6, the source DU generates the execution condition corresponding to the candidate cell / candidate configuration based on the third message, and sends a fourth message containing the second information to the CU.

[0365] 1.4 S7-8 is not required to be executed.

[0366] 1.5 S9-12, the CU determines the conditional mobility configuration based on the fourth message sent by the source DU, and sends it to the UE through the RRC reconfiguration message. After receiving the RRC reconfiguration message, the UE sends an RRC reconfiguration complete message to the CU. The conditional mobility configuration is completed.

[0367] In the above process, the source DU and the target DU can be the same or different.

[0368] For case 2: if the Subsequent Conditional Mobility is supported, the CU needs to negotiate the execution condition of the initial Conditional Mobility with the source DU, and the CU also needs to negotiate the execution condition of the Subsequent Conditional Mobility with the candidate DU, (the negotiation process of the execution condition of the Subsequent Conditional Mobility is initiated after the CU determines which of the first candidate cells' mobility requests are accepted), then the following steps are included:

[0369] 2.1 Same as 1.1 above.

[0370] 2.2 S3~4, same as 2.2.

[0371] 2.3 S5~6, same as 1.3, based on this process, the source DU generates the execution condition of the initial Conditional Mobility for all the accepted first candidate cells.
