Some concepts and/or terms related to the measurement and reporting methods, apparatuses, devices, systems and storage media provided by the embodiments of the present application are explained below.

1. Activation and dormancy of Secondary cells (scells):

based on the inter-frequency L3 measurement report of the UE, the network may configure some scells and directly configure its bandwidth Part (BWP) into a dormant state; SCell and SpCell (i.e., primary Cell (PCell) +primary secondary Cell (Primary Secondary Cell, PSCell)) must be in the same DU.

The network may ensure that the dormant SCell is frame synchronized with the SpCell. From the UE reception point of view, it is only possible that the SCell is not co-located with the SpCell, and some synchronization error is caused by the path propagation delay, and it is usually not more than 33us (assuming that the base station coverage radius is 9km, the inter-station synchronization error is 3 us).

In the SCell dormant state, the UE still needs to perform periodic and semi-static channel state information (Channel State Information, CSI) measurements, L1 (i.e., layer 1) measurements and L3 (i.e., layer 3) measurements in the dormant SCell; the measurement results are not reported on dormant scells, but need to be reported on spcells, or on scells including physical uplink control channels (Physical Uplink Control Channel, PUCCH) that are not dormant.

The dormant SCell does not receive and send any data, including blind detection of a physical downlink control channel (Physical Downlink Control Channel, PDCCH), reception of a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), and transmission of a physical random access channel (Physical Random Access Channel, PRACH)/physical uplink shared channel (Physical Uplink Shared Channel, PUSCH)/PUCCH/sounding reference signal (Sounding Reference Signal, SRS); if beam failure occurs in the SCell beam failure recovery (Beam Failure Recovery, BFR) process, the UE transmits PUCCH on a corresponding uplink grant (UL grant); if there is no UL grant, the UL grant may be requested by sending a scheduling request (Scheduling Request, SR) on SpCell or non-dormant PUCCH SCell.

UL Timing Advance (TA) of SCell and SpCell may be in the same Timing Advance Group (Timing Advance Group, TAG) or may be in different TAGs, but only 2 TAGs at most are contained in one Cell Group (CG). The TAG is a set of cells comprising at least one serving cell, which may be a PCell, a PSCell or an SCell. Because SCell and SpCell in the same CG are in the same DU, the network may update the TA on the TAG corresponding to the SCell through a MAC Control Element (Media Access Control-Control Element, MAC CE) on the SpCell or on the SCell that is not dormant. In general, if there is one SCell that is not co-located with the SpCell, the network will not typically deactivate that SCell for the purpose of maintaining the TA.

2. Deactivation of PSCell, L1 measurement in deactivated state

The network may configure the UE with an inactive PSCell, which may not have a frame synchronization relationship with the active serving cell, i.e., the PCell.

No L1 measurements need to be performed on the inactive PSCell, but radio link monitoring (Radio link monitoring, RLM)/beam failure detection (Beam Failure Dection, BFD) measurements need to be performed; on the inactive PSCell, if the UE finds a beam failure, it needs to report in the radio resource control (Radio Resource Control, RRC) layer as secondary cell group (Secondary Cell Group, SCG) failure.

3. The same-frequency neighbor cell L1 is measured;

the network may be configured in a synchronization signal block (Synchronization Signal Block, SSB) from the neighboring cell, and as an available SSB for the current serving cell, the UE may perform Layer 1 measurement and Layer 1reference signal received power (Layer 1Reference Signal Received Power,L1-RSRP) reporting on the corresponding SSB.

The frequency point of the neighbor cell SSB and the frequency point of the serving cell must be consistent, and both must be within the bandwidth of the active BWP; for a UE with Single FFT only, the reception timing error of the SSB of the neighbor cell and the SSB of the serving cell needs to be guaranteed to be smaller than the length of the Cyclic Prefix (CP).

4. Conditional switching

The network configures switching conditions for the UE in advance; when the UE judges that the condition is met, the UE initiates switching from one cell to another cell; the network forwards data (data forward) for the corresponding data bearer in advance.

5. L3 measurement

L3 measurement is also an L1 measurement in nature, also commonly referred to as mobility measurement; compared with L1 measurement, the L3 measurement is different in application, and the L3 measurement is mainly used for neighbor cell discovery and a series of mobile network decisions such as L3 handover and the like.

For L3 measurements, there are on-frequency measurements and off-frequency measurements. When the measurement frequency point is identical to the serving cell, the measurement frequency point can be regarded as the same-frequency measurement, otherwise, the measurement frequency point can be regarded as the different-frequency measurement.

For L3 measurement, the UE only needs to measure SSB, and the measurement result only reports the current serving cell; when the service cell and the neighbor cell are in different DUs or even different Centralized Units (CUs), only L3 data can be communicated, and L1/L2 data cannot be communicated.

In FR2, L3 measurements the UE will use a wide beam to guarantee cell discovery (Cell identification), which is different from the beam used by the UE in L1 measurements.

The measurement and reporting method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Currently, the UE may determine L1 cell quality and report to the network through L1 measurement of the same frequency or different frequencies, so that the network may initiate a connection state mobility management (RRM) event based on L1/L2, such as cell handover, cell redirection, SCG/SCell loading, etc.

(1) L1 measurements can only be made in an activated SpCell or SCell. After the network needs to configure and activate the SpCell or the SCell, the UE can perform L1 measurement; although the activated SCell may be in a dormant state, and data transceiving is not required on the SCell in the dormant state, only DL measurement is required to be continuously performed, such a mechanism is only applicable to the situation that the SCell and the SpCell are under the same DU and supported by the current protocol version, that is, the network may perform TA management, beam management and power management through DL and UL links of the activated cell. For the situation that the measured cell and the serving cell are under different DUs in the L1 measurement, the existing L1 measurement and reporting mechanism cannot be used.

(2) The L1 measurement needs to be measured for the corresponding cell after the network activates the SCell first, so that the current L1 measurement cannot be performed in advance for the frequency point or the UE BWP configuration where the SCell is not activated.

(3) The L3 measurement is mainly used for cell discovery and search, and its performance requirement and implementation are completely different from the L1 measurement used for beam management, for example, the Rx beam gain used by the L1 measurement is generally higher than that of the L3 measurement; thus, the results of the L1 measurement and the L3 measurement cannot generally be directly compared; therefore, it is not suitable to use the intermediate result of the L3 measurement, i.e., the L1 result, to complete the L1 measurement result serving as a neighbor cell.

(4) In the condition handover, a handover preparation can be made between a CU and a DU of the network, and the handover is directly completed based on a random access channel (Random Access Channel, RACH) sent by the UE, but the UE can only initiate the handover based on the L3 measurement result, that is, the UE cannot perform L1 measurement on an unknown cell, and the corresponding L1 report must also be performed after the condition handover is completed.

In view of the above problems, in the embodiment of the present application, when a measured cell and a serving cell are in different DUs, a UE may perform L1 measurement according to measurement configuration information configured by a network side, and specifically, the UE performs L1 measurement based on bandwidth configuration of an L1 measurement reference signal, so as to implement L1 measurement; in addition, the UE may report the measurement result of the L1 measurement according to the reporting configuration information configured by the network side, specifically, the UE reports based on the indicated target cell set, so as to implement the L1 measurement reporting; the application definitely gives that the L1 measurement by the UE is based on the bandwidth configuration of the L1 measurement reference signal, and the L1 reporting by the UE is based on the scheme of the target cell set reporting, so that the network measurement equipment can perform mobility management and link quality management in advance according to the bandwidth configuration of the UE based on the L1 measurement reference signal and the measurement result reported by the target cell set, and the UE can perform high-quality data transmission, thereby improving the data transmission performance of the UE.

Specifically, an embodiment of the present application provides a measurement and reporting method, and fig. 2 shows a flowchart of the measurement and reporting method provided by the embodiment of the present application. As shown in fig. 2, the measurement and reporting method provided by the embodiment of the present application may include the following steps 201 to 204.

Step 201, the network side device sends target configuration information to the UE.

Step 202, the UE receives target configuration information sent by the network side device.

In the embodiment of the present application, the target configuration information includes measurement configuration information and reporting configuration information, where the measurement configuration information is used for L1 measurement by the UE to obtain an L1 measurement result, and the reporting configuration information is used for sending the L1 measurement result to the network side device.

In the embodiment of the present application, the measurement configuration information is determined by a first parameter set, where the first parameter set includes bandwidth configuration of an L1 measurement reference signal; the reporting configuration information is determined by a second parameter set, and the second parameter set comprises first indication information, wherein the first indication information is used for indicating the UE to carry out L1 measurement reporting on a corresponding target cell set.

It should be noted that, the first indication information for indicating the UE to perform the L1 measurement reporting to the corresponding target cell set may be understood as: the first indication information is used for indicating the UE to report the L1 measurement on the target cell set; or the first indication information is used for indicating that the resources when the UE performs the L1 measurement reporting are on the target cell set; or, the first indication information is used for indicating that the measurement result of the L1 measurement report performed by the UE is the measurement result of the cell in the target cell set.

Alternatively, in the embodiment of the present application, the bandwidth configuration of the L1 measurement reference signal may be a system bandwidth configuration or a BWP configuration.

Optionally, in the embodiment of the present application, the target cell set and the serving cell of the network side device are under different DUs (i.e., the gNB MACs are different).

Optionally, in the embodiment of the present application, the network side device may issue the target configuration information through RRC configuration to instruct the UE to perform L1 measurement on one or more L1 measurement configurations, and instruct the UE to perform reporting of the L1 measurement result on one or more L1 reporting configurations.

Optionally, in an embodiment of the present application, the measurement configuration information may be uniquely determined by a first parameter set, and the reporting configuration information may be uniquely determined by a second parameter set. It should be noted that "uniquely determining" here means that the above measurement configuration information/reporting configuration information is distinguished into two different configurations if and only if there is an inconsistency in at least one parameter in the first set of parameters.

Optionally, in an embodiment of the present application, the first parameter set further includes at least one of the following:

l1 measures the resource allocation of the reference signal;

l1 measures the district configuration that the reference signal corresponds to;

The L1 measurement reference signal corresponds to the reporting configuration of the cell.

Optionally, in an embodiment of the present application, the resource configuration of the L1 measurement reference signal may include at least one of the following: frequency point, resource Block (RB) allocation, period, etc.

Optionally, in the embodiment of the present application, the Cell configuration corresponding to the L1 measurement reference signal may include a Physical Cell ID (PCID) of a Cell; the reporting configuration of the cell corresponding to the L1 measurement reference signal may include a cell set indication.

Optionally, in an embodiment of the present application, the second parameter set further includes at least one of the following:

reporting a cell set indication corresponding to the configuration information;

reporting TAG indication of a cell set corresponding to the configuration information;

an activation time window configured on the target cell set, where the activation time window is used to monitor the PDCCH issued in the target cell set;

at least one PUCCH resource configured on the target cell set, wherein the at least one PUCCH resource is used for reporting a beam measurement result and CSI information;

SRS resources configured on the target cell set, wherein the SRS resources are used for sending SRS; to determine synchronization information.

Optionally, in an embodiment of the present application, the activation time window may include at least one of a period, a system frame number (System Frame Number, SFN) offset (offset), and a time window length; the activation time window may be configured by a search space (search space) and may be used to listen to PDCCHs issued within the target cell set (the RNTI corresponding to this scheduling signaling is not a C-RNTI).

Optionally, in an embodiment of the present application, the PDCCH is used for at least one of the following:

transmitting power adjustment information, wherein the power adjustment information is used for indicating that the power reported by the L1 measurement of the cells in the target cell set is adjusted;

triggering the UE to execute a process of transmitting RACH (RACH of PDCCH order) by issuing a PDCCH command; to facilitate TA maintenance on the corresponding cell;

transmitting a timing advance command for adjusting the TA;

l1 or L2 signaling for informing the UE that the mobility state is changed is transmitted.

Optionally, in the embodiment of the present application, the timing advance Command (TA Command) may be MAC CE or downlink control information (Downlink Control Information, DCI).

Step 203, the UE performs L1 measurement according to the measurement configuration information to obtain an L1 measurement result, and sends the L1 measurement result to the network side device according to the reporting configuration information.

Optionally, in the embodiment of the present application, the "UE performs L1 measurement according to measurement configuration information in the above step 203 to obtain an L1 measurement result" may be specifically implemented by the following step 203 a.

Step 203a, the UE performs L1 measurement on the plurality of cells on the L1 measurement frequency layer according to the measurement configuration information, to obtain an L1 measurement result.

In the embodiment of the present application, the plurality of cells belong to N synchronization cell groups, and a downlink receiving timing synchronization error between each cell in each synchronization cell group satisfies a preset condition, where N is a positive integer.

Optionally, in the embodiment of the present application, the preset condition may be that in each synchronization cell group, a downlink Rx timing synchronization error between each cell does not exceed a CP length.

Optionally, in an embodiment of the present application, the bandwidth is configured as BWP. Under the condition that BWP of the first cell is different from active BWP of a service cell of the network side equipment, the L1 measurement frequency layer is an inter-frequency L1 measurement frequency layer, and L1 measurement corresponding to the inter-frequency L1 measurement frequency layer is L1 measurement outside a measurement interval; in case the BWP of the first cell is the same as the active BWP of the serving cell, the L1 measurement frequency layer is the same frequency L1 measurement frequency layer. The first cell is a cell in which the UE performs L1 measurement, and the L1 measurement frequency layer is a frequency layer in which the UE performs L1 measurement.

It can be understood that when the cell BWP where the L1 measurement is located and the active BWP of the serving cell do not overlap, it can be regarded as a different-frequency L1 measurement frequency layer; the method comprises the steps of carrying out a first treatment on the surface of the When the BWP of the cell where the L1 measurement is located is within the active BWP of the serving cell, the BWP can be regarded as a common frequency measurement frequency layer. For the inter-frequency L1 measurement frequency layer, the UE may measure outside of the measurement interval (gap) at the L1 measurement, or may measure within the measurement interval.

Optionally, in the embodiment of the present application, before "sending the L1 measurement result to the network side device according to the reporting configuration information" in the above step 203, the measurement and reporting method provided in the embodiment of the present application further includes the following step 301.

Step 301, the UE performs uplink synchronization operation on the neighboring cell.

In the embodiment of the present application, the uplink synchronization operation includes at least one of the following:

transmitting an uplink signal to network side equipment on a neighboring cell to determine uplink TA;

transmitting PUCCH and/or SRS to network side equipment on a neighbor cell to determine the adjustment amount of TA;

and under the condition that the UE monitors that the downlink synchronization error is smaller than or equal to a preset threshold, non-contention random access (Contention Free Random Access, CFRA) is initiated on a cell set corresponding to the neighbor cell, and uplink synchronization is established.

After uplink synchronization is established, the TAG corresponding to the adjacent cell is in an activated state.

It can be appreciated that before the UE reports the L1 measurement result to a certain neighboring cell, the UE needs to establish uplink synchronization on the neighboring cell, for example, by sending an uplink signal and receiving feedback signaling of the network, to determine the uplink TA.

Step 204, the network side device receives the L1 measurement result sent by the UE.

The embodiment of the application provides a measurement and reporting method, when a measured cell and a service cell are in different DUs, UE can carry out L1 measurement according to measurement configuration information configured by a network side, specifically, the UE carries out L1 measurement based on bandwidth configuration of an L1 measurement reference signal so as to realize L1 measurement; in addition, the UE may report the measurement result of the L1 measurement according to the reporting configuration information configured by the network side, specifically, the UE reports based on the indicated target cell set, so as to implement the L1 measurement reporting; the application definitely gives that the L1 measurement by the UE is based on the bandwidth configuration of the L1 measurement reference signal, and the L1 reporting by the UE is based on the scheme of the target cell set reporting, so that the network measurement equipment can perform mobility management and link quality management in advance according to the bandwidth configuration of the UE based on the L1 measurement reference signal and the measurement result reported by the target cell set, and the UE can perform high-quality data transmission, thereby improving the data transmission performance of the UE.

Optionally, in the embodiment of the present application, before the step 201, the measurement and reporting method provided in the embodiment of the present application further includes the following steps 401 and 402.

Step 401, the UE sends capability information to the network side device.

Step 402, the network side device receives capability information sent by the UE.

In an embodiment of the present application, the capability information includes at least one of the following:

whether the UE supports carrier aggregation (Carrier Aggregation, CA) combination corresponding to the inter-frequency L1 bandwidth configuration;

on each different-frequency L1 measurement frequency layer, the number of synchronous cell groups supported by the UE;

the maximum number of activation TAGs that the UE can handle (including TAGs corresponding to the L1 inter-frequency layer).

In the embodiment of the application, the capability information is used for configuring measurement configuration information and/or reporting configuration information for the UE by the network side equipment according to the capability information.

Optionally, in the embodiment of the present application, after the step 204, the measurement and reporting method provided in the embodiment of the present application further includes the following steps 501 and 502.

Step 501, the network side device sends a target signaling to the UE according to the L1 measurement result.

In the embodiment of the present application, the target signaling is used to instruct the UE to perform mobility management related operations. Wherein the mobility management related operations include at least one of: cell handover, cell redirection, SCG or secondary cell loading.

Step 502, the UE receives a target signaling sent by a network side device.

In the embodiment of the application, the target signaling is obtained by the network side equipment according to the L1 measurement result.

It may be appreciated that the network side device may issue the target signaling (e.g., the L1 signaling or the L2 signaling) based on the L1 measurement result reported by the UE, and perform mobility management on the UE, where the mobility management includes at least one of cell handover, cell redirection, and SCG/SCell loading.

Optionally, in the embodiment of the present application, after the step 204, the measurement and reporting method provided in the embodiment of the present application further includes the following steps 601 and 602.

Step 601, in the case that the UE receives the handover signaling in the target cell, the UE sends second indication information to the source cell.

In the embodiment of the present application, the target cell is a cell to be switched by the UE, the switching signaling is used to instruct the UE to switch to the target cell, and the second instruction information is used to instruct the source cell to stop data transmission.

Optionally, in the embodiment of the present application, the control plane bearer of the target cell is activated after the handover is completed; i.e. for the handover scenario, the control plane bearer of the target cell is activated after L1/L2 handover is completed.

Step 602, the UE receives Acknowledgement (ACK) information sent by the source cell, and sends a notification message of handover completion to the target cell.

It can be understood that after the UE receives the L1 handover signaling in the target cell, the UE may notify the source cell to stop data transmission through the L1/L2 signaling; and after receiving the ACK information sent by the source cell, sending L1/L2 signaling to the target cell to inform that the switching is completed.

Optionally, in the embodiment of the present application, the CU may copy the radio link control (Radio Link Control, RLC) data packets, and transmit the data flows on the data bearers corresponding to the UE to the RLC entities of the two DUs in real time, where the two RLC entities perform the encapsulation of the data packets according to the same logic.

Optionally, in the embodiment of the present application, before the L1/L2 handover is completed, the corresponding target DU discards part of the timeout data of the UE.

Optionally, in the embodiment of the present application, when the UE replies to the target DU and the L1/L2 handover is completed, the UE may carry ACK number information of the uplink and downlink RLC data packets.

Alternatively, in the embodiment of the present application, the above-mentioned L1/L2 signaling may be understood as BWP handover signaling (similar to the SCell exiting from dormant (dormant) state).

Optionally, the embodiment of the application is applied to inter-cell handover scenes, cell redirection scenes, SCG/auxiliary cell loading scenes and the like, and specific processes of the measurement and reporting method provided by the embodiment of the application are described by taking inter-cell handover scenes of different DUs under the same CU as an example. As shown in fig. 3, the measurement and reporting method provided in the embodiment of the present application includes the following steps 21 to 28.

Assuming that the UE is conducting data transmission on the source cell (i.e., source cell DU), the present application may complete the cell handover to the target cell by:

step 21, the source cell configures an L3 measurement event for the UE through an RRC reconfiguration message.

In the embodiment of the present application, the frequency point of the L3 measurement event includes a frequency point corresponding to the SSB of the target cell. Based on the L3 measurement event configuration of the network, the UE performs cell discovery and L3 measurement on the corresponding SSB frequency points.

Step 22, the UE reports the measurement report after finding the target cell and completing the L3 measurement.

In the embodiment of the application, when the SSB of the target cell meets the condition detectable by the UE, namely, the UE discovers the target cell through the cell discovery process, the UE can perform L3 measurement, report the measurement result of the target cell to the source cell and forward the measurement result to the CU through the source cell DU.

Step 23, the source cell DU configures the BWP to be switched of the target cell through the RRC reconfiguration message, so that the UE performs link maintenance in advance according to the configured BWP.

In the embodiment of the present application, the CU configures a target cell corresponding to another DU as a "to-be-switched" cell based on the L3 measurement result, and configures a set of DL BWP and UL BWP in a "to-be-switched" state for the cell, which may also be referred to as "dormant" BWP, and some reference signal configurations and reporting configurations associated to the BWP, so as to facilitate link maintenance of the UE.

It should be noted that, if there is more than one target cell, the network side device may further configure a target cell set, where all cells in the target cell set belong to the same DU, and the configuration of BWP to be handed over of the target cells is completely consistent, that is, the target cells are called as the target cell set. The network side equipment can instruct the UE to report the L1 measurement on the DU corresponding to the target cell set through the indication information in the reporting configuration.

Exemplary, as shown in fig. 4, a schematic diagram of two active links is provided in an embodiment of the present application. The configuration of the BWP to be handed over may comprise at least one of the following for the "dormant" BWP of the target cell and the active BWP of the source cell: PDSCH configuration, PDCCH configuration, PUSCH configuration, PUCCH configuration, necessary reference signal configuration, QCL configuration, etc., according to which the UE may perform link maintenance.

In addition, the L1 measurement configuration (i.e., the measurement configuration information described above) may include at least one of:

measurement reference signal configurations, such as frequency points, RB allocation, period, etc.;

measuring cell configuration corresponding to the reference signal, for example, cell PCID and the like;

the measurement reference signal corresponds to a reporting configuration of the cell, such as a cell set indication or the like.

It should be noted that, the L1 measurement configuration and the reporting configuration are both related to a certain BWP to be switched, and the BWP to be switched and the corresponding target cell set thereof have the following different points compared with the source target cell set:

(1) The monitoring of the PDCCH corresponding to the BWP to be switched is periodic, and there is a configuration of one period and time offset. The PDCCHs monitor the corresponding search space, and the UE does not need to detect DCI based on the C-RNTI; the scheduling signaling issued by these PDCCHs is used for at least one of the following:

notifying corresponding reported power adjustment information;

triggering the RACH of PDCCH order, so that the TA maintenance on the corresponding cell is facilitated;

transmitting a TA Command for adjusting the TA, which may be MAC CE or DCI;

L1/L2 signaling informing the UE of the mobility state change.

(2) The cell or set of cells corresponding to the BWP to be switched maintains an independent TAG, i.e. a TAG different from the active cell; after receiving the configuration of the BWP to be switched, the UE sends RACH to the network side device at an appropriate time, and receives a TA update command in the PDCCH activation time, including PDCCH order, to maintain the TA, where a specific maintenance method includes at least one of the following:

determining an uplink TA by sending an uplink signal and receiving a feedback signaling of a network;

The network determines the adjustment amount of the TA based on the PUCCH and/or SRS transmission;

after the uplink synchronization is established, the TAG corresponding to the adjacent cell is in an activated state.

(3) The CSI calculation and reporting configured on the BWP to be switched, and the L1-RSRP calculation and reporting may be directly sent to the corresponding cell through the UL channel (PUSCH or PUCCH) according to the quasieco-Location (QCL) information corresponding to the BWP to be switched.

(4) If the BWP to be switched of the target cell and the active BWP of the serving cell do not overlap, for example, on different predefined frequency bands, the BWP to be switched of the target cell can be regarded as a different frequency band layer; when the BWP of the cell where the L1 measurement is located is within the active BWP of the serving cell, the BWP can be regarded as a common frequency measurement frequency layer.

The inter-frequency L1 measurement is performed outside the measurement interval; if the UE supports CA or DC on the L1 inter-frequency measurement frequency layer, the UE does not need a measurement interval for measurement on the L1 inter-frequency measurement frequency layer; the UE capability of CA or DC is per-Band Combination (per-BC) capability, i.e. different Band combinations for which the UE can report a capability value.

On each L1 measurement frequency layer, the UE may perform L1 measurements for more than 1 cell, but multiple cells may only belong to N synchronization cell groups; within each synchronization cell group, the downlink Rx timing synchronization error among a plurality of cells does not exceed the CP length. The number of synchronization cell groups supported by the UE is also UE capability; this is one per-band per-BC capability, i.e. a different band combination, for each of which the UE can report a capability value.

L1 measurement and reporting must be performed in a measurement interval in some cases, and when a synchronous cell group corresponding to a to-be-switched BWP configured by a network is greater than the capability of the UE, or a TAG corresponding to the to-be-switched BWP exceeds the maximum capability which can be supported by the UE, the UE can perform L1 measurement and reporting in the measurement interval; the maximum number of active TAGs (TAG corresponding to the L1 inter-Frequency measurement Frequency layer) that can be handled by the UE is also a UE capability, which may be per-Frequency range (per-FR) capability or per-UE capability, where per-FR capability refers to the UE reporting a capability value for each Frequency range, and per-UE capability refers to the UE reporting capability without distinguishing between Frequency ranges, and the entire UE only reports a capability.

The number of L1 inter-frequency measurement frequency layers is UE capability; per-UE/per-FR capability.

The number of L1 measurement neighbor cells is UE capability; per-UE/per-FR capability.

Step 24, the UE sends RACH, establishes connection with the target cell, and maintains the connection, including uplink TA maintenance, uplink power control, downlink CSI feedback, downlink beam measurement reporting, and so on.

Specifically, after the UE monitors that the downlink synchronization error is smaller than a certain threshold, the UE triggers to initiate CFRA on the corresponding cell set, establishes synchronization, and starts to feed back CSI and/or beam measurement results.

Step 25, the target cell DU activates the non "pre-handover" BWP of the target cell and its corresponding transmission configuration indication (Transmission configuration Indication, TCI) simultaneously by MAC CE or DCI signaling.

In the embodiment of the application, the target cell DU activates the non-pre-switching BWP of the target cell and the corresponding TCI at the same time, so that the UE can perform uplink and downlink transmission on the BWP with better quality.

It should be noted that, here, the better quality means: the rate of transmission is higher (e.g., above a certain threshold), or the MCS (Modulation and coding scheme, modulation and coding scheme number) and/or the number of MIMO transmission layers used for transmission is higher (e.g., above a certain threshold), or the bit error rate and/or the block error rate is lower (e.g., below a certain threshold).

In the embodiment of the present application, the above-mentioned MAC CE or DCI signaling may be understood as BWP handover signaling (similar to the exit of SCell from the dorandy state).

In step 26, the UE reports the source base station through the MAC CE, and needs to switch to the target DU, so that the uplink and downlink transmissions need to be stopped.

Step 27, the source cell DU informs the UE that the uplink and downlink transmission is stopped through the MAC CE.

Step 28, the UE sends MAC signaling to notify the RLC data packet sending condition of the target cell DU in the source cell DU, and completes handover.

The CU copies the RLC data packets, transmits data streams on data bearers corresponding to the UE to the RLC entities of the two DUs in real time, and the two RLC entities carry out the encapsulation of the data packets according to the same logic;

before the L1/L2 switching is completed, the corresponding target DU discards part of overtime data of the UE;

when the UE replies the target DU and the L1/L2 switching is completed, the UE carries ACK number information of uplink and downlink RLC data packets;

aiming at a switching scene, the control surface of a target cell bears and is activated after L1/L2 switching is completed;

so far, the UE completes the handover and starts to perform data transmission on the target cell DU.

It should be noted that, the above steps 25-28 are exemplary descriptions of the procedure of performing the subsequent L1/L2 handover after the network side device receives the L1 measurement result, and the embodiment of the present application is not limited to this procedure.

It can be appreciated that, for a neighboring cell of an Inter-DU (Inter-DU), the network-side device gives a dormant (dorman) like BWP configuration of the neighboring cell for measurement and reporting while configuring SSB measurement for the neighboring cell. After the UE needs to activate the dormant BWP, the measurement configuration and the reporting configuration are associated to the dormant BWP, and measurement is performed using downlink resources configured on the dormant BWP, and L1 measurement reporting is performed using uplink resources configured on the dormant BWP.

The dormant BWP of this neighbor cell may have an independent TAG configuration; on dormant BWP, the UE needs to perform L1 measurement and link maintenance, including RLM, BFD, TA maintenance, uplink power control, CSI feedback, etc. The UE may receive the PDCCH on the dormant BWP of the neighboring cell according to a certain "activation time window" configuration, and the DCI received in the PDCCH may be used to transmit TA adjustment (including PDCCH order), uplink power control reported by L1 measurement, and L1/L2 cell handover signaling (equivalent to BWP activation/deactivation signaling) without using C-RNTI scrambling.

It can be understood that, because there is no C-RNTI on the dormant BWP, no data packet corresponding to the actual uplink and downlink data bearers is transmitted; the CU of the network-side device may copy two copies of the data packet to two independent DUs, and start transmitting the data packet corresponding to the data bearer after completing activation of non-dormant BWP of the target cell. Before activating the non-dormant BWP of the target cell, the target cell DU obtains the current packet bearer transmission situation (e.g., RLC packet ACK sequence number of DL/UL reported by the UE) from the CU or UE.

It should be noted that if the bandwidth of the dormant BWP is completely within the bandwidth of the currently active BWP, or the two are identical, the measurement is recorded as the same-frequency L1 measurement; otherwise, the measurement is marked as inter-frequency L1 measurement. The measurement behavior of the UE on dormant BWP depends on the capability of the UE, i.e. the capability information described above.

In the embodiment of the application, for the different-frequency DU scene, the UE can finish the measurement of the neighbor cell in advance before switching and finish the important neighbor cell link maintenance process, so that after switching, important information such as CSI and the like of a new service cell can be directly transmitted in high quality without a series of lengthy processes.

It should be noted that, in the measurement and reporting method provided by the embodiment of the present application, the execution body may also be a measurement and reporting device, or a control module in the measurement and reporting device for executing the measurement and reporting method.
