Description

Method for reporting measurement report and related product

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for reporting a measurement report and a related product.

Background

For an unlicensed NR-U band in a New Radio (New Radio) NR system, a third generation partnership project 3GPP RAN working group agreed to a standing work of an NR unlicensed working mode (WID RP-182878) in 2018 in month 12, where the target of the project is to make NR work in the unlicensed band, and the project includes the following working scenarios:

(1) a carrier aggregation scenario: the PCell is an authorized frequency spectrum, and SCells working on an unauthorized frequency spectrum are aggregated in a carrier aggregation mode;

(2) double-connection working scene: the PCell is an LTE authorized frequency spectrum, and the PScell is an NR unauthorized frequency spectrum;

(3) independent working scene: NR operates in unlicensed spectrum as an independent cell

Generally, the operating Band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum (e.g., US5925-7125MHz, or European5925-6425MHz, etc.); on unlicensed spectrum, the design of NR-U should guarantee fairness with other systems already operating on these unlicensed spectrum, such as wireless high fidelity WiFi and the like. The principle of fairness is that the impact of NR-U on systems already deployed on unlicensed spectrum (e.g., WiFi) cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems over unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. A general energy detection mechanism is an listen before transmit LBT mechanism, and the basic principle of the mechanism is that a base station or a terminal (transmission end) needs to listen for a period of time according to a rule before transmitting data on an unlicensed spectrum. If the sensed result indicates that the channel is in an idle state, the transmitting end may transmit data to the receiving end. If the interception result indicates that the channel is in an occupied state, the transmission end needs to back off for a period of time according to the specification and then continues to intercept the channel until the channel interception result is in an idle state, and data can not be transmitted to the receiving end.

For a scenario that a terminal is switched from an NR-U cell to another cell, the terminal needs to perform channel sensing and preemption operation based on an LBT mechanism, and report a measurement report when channel preemption is successful, so that the channel sensing and preemption operation may affect the real-time performance of the measurement report.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

By way of example, fig. 1A illustrates a wireless communication system to which the present application relates. The wireless communication system 100 may operate in a high frequency band, and may be a New Radio (NR) system, a Long Term Evolution (LTE) system, a 5G NR and LTE combined networking system, and the like in the fifth Generation mobile communication (5G) of future Evolution. As shown, the wireless communication system 100 may include: one or more network devices 101, one or more terminals 103, and a core network device 105. Wherein: the network device 101 may be a base station, and the base station may be configured to communicate with one or more terminals, and may also be configured to communicate with one or more base stations having partial terminal functions (e.g., communication between a macro base station and a micro base station, such as an access point). The Base Station may be a Base Transceiver Station (BTS) in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, or an evolved Node B (eNB) in a Long Term Evolution (LTE) system, or a Base Station gNB in a 5G system or an NR system. In addition, the base station may also be an Access Point (AP), a transmission node (Trans TRP), a Central Unit (CU), or other network entity, and may include some or all of the functions of the above network entities. The core network device 105 includes a device on the core network side such as a Serving GateWay (SGW). The terminals 103 may be distributed throughout the wireless communication system 100 and may be stationary or mobile. In some embodiments of the present application, the terminal 103 may be a mobile device (e.g., a smart phone), a mobile station (mobile station), a mobile unit (mobile unit), an M2M terminal, a wireless unit, a remote unit, a User agent, a User Equipment (UE) mobile client, and so on.

It should be noted that the wireless communication system 100 shown in fig. 1A is only for more clearly illustrating the technical solution of the present application, and does not constitute a limitation to the present application, and as a person having ordinary skill in the art knows, the technical solution provided in the present application is also applicable to similar technical problems as the network architecture evolves and new service scenarios emerge.

The related art to which the present application relates is described below.

Currently, as shown in fig. 1B, the main process of the terminal performing cell handover includes: handover preparation, handover execution, and handover completion. The switching preparation means that the source base station configures the terminal to perform measurement reporting, and sends a switching request to the target base station based on the reporting result of the terminal. When the target base station agrees to the handover request, a Radio Resource Control (RRC) message (e.g., mobility Control information) including a Random Access Channel (RACH) Resource, a cell Radio network temporary identifier (C-RNTI), a target base station security algorithm, a system message of the target base station, and the like is configured for the terminal. The switching execution comprises that the source base station transmits the mobile control information to the terminal, and the terminal initiates a random access flow to the target base station after receiving the switching command. Meanwhile, the source base station sends a sequence Number STATUS TRANSFER (SN STATUS TRANSFER) to the target base station, and is configured to inform the target base station of a Packet Data Convergence Protocol (PDCP) sequence Number (Serial Number, SN) receiving STATUS and a downlink PDCP SN sending STATUS. The switching completion includes that after the terminal is successfully accessed to the target base station (random access is successful), the target base station sends a path switching request (PATH SWITCH REQ) to the terminal ST, a Mobility Management Entity (MME) is requested to switch a downlink path, and after the path switching (path switch) is completed, the target base station indicates the source base station to release the terminal context, so that the switching is completed.

For some special scenarios, such as high-speed movement or high-frequency conditions, frequent switching is required. Conditional handover (conditional handover) can avoid the problem that the time for handover preparation is too long, which causes the time for the terminal to handover to be late, and as shown in fig. 1C, a handover command HO command can be configured in advance for the terminal. On the other hand, for a high-speed rail scene, the operation track of the terminal is specific, so the base station can allocate the target base station to the terminal in advance, and the handover command HO command includes a condition for triggering the terminal to perform handover, and when the allocated condition is satisfied, the terminal initiates an access request to the target base station. The 3GPP RAN2#104 conference has agreed with a conditional handover and supports the configuration of multiple target cells in the HO command of the conditional handover. And the terminal judges which target cell is accessed based on the configured condition.

Dual-Connectivity (DC) is an important technology introduced by 3GPP Release-12 Release. With the dual connectivity technology, the LTE macro and small stations can utilize the existing non-ideal backhaul (non-ideal backhaul) X2 interface to implement carrier aggregation, thereby providing higher rate for users. The terminal supporting double connection can be connected with two LTE base stations simultaneously, and the throughput of a single user is increased. In the deployment process of the 5G network, the 5G cell can be used as a macro coverage independent network, and can also be used as a small station to perform coverage and capacity enhancement on the existing LTE network. 3GPP Release-14 defines the dual connection technology of LTE and 5G on the basis of the LTE dual connection technology. The LTE/5G dual connection is a key technology for realizing LTE and 5G fusion networking and flexible deployment scene by an operator. The rapid deployment can be realized based on the existing LTE core network in the early 5G period, and the comprehensive network coverage can be realized by the combined networking of the LTE and the 5G in the later period, so that the wireless resource utilization rate of the whole network system is improved, the system switching time delay is reduced, and the user performance and the system performance are improved.

In the 3GPP mobility enhancement subject, an optimization method for reducing the interruption time during handover is proposed, which includes the following two architectures: the DC based HO is characterized in that a target base station is added as SN during switching, then the SN (target base station) is changed into MN through role change signaling, and finally a source base station is released, so that the effect of reducing the interruption time during switching is achieved. And 2, eMBB based HO, based on the existing switching process, the UE continuously keeps the connection with the source base station and simultaneously initiates random access to the target base station when receiving the HO command, and the connection of the source base station is not released until the access of the UE and the target base station is completed.

At present, for a scenario that a terminal is switched from an NR-U cell to another cell, the terminal needs to perform channel sensing and preemption operation based on an LBT mechanism, and report a measurement report when channel preemption succeeds, so that the channel sensing and preemption operation affects the real-time performance of the measurement report. The terminal sends a measurement report to the base station under the condition that the channel is successfully preempted after one or more times of channel preemption failures, and at the moment, the base station cannot accurately know the generation time of the measurement report, so that the switching failure is caused.

In view of the above problems, the embodiments of the present application propose the following embodiments, which are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for reporting a measurement report according to an embodiment of the present application, where the method is applied to the exemplary communication system, and the method includes:

in part 201, a terminal acquires a measurement configuration from a first network device, and performs measurement according to the measurement configuration to obtain a measurement report;

the terminal performs cell measurement operation to obtain a measurement result and generates a measurement report according to the measurement result when the handover measurement event meets a preset condition.

In part 202, the terminal sends the measurement report to the first network device and notifies the first network device of the generation time of the measurement report in a preset manner.

The preset mode is a rule preset by the terminal and the network device, and specifically includes a first indication information indication, a second indication information indication, a hidden indication, and the like, which is not limited uniquely here.

The generation time of the measurement report specifically refers to a time when the terminal successfully occupies the channel. In specific implementation, after receiving measurement configuration, the terminal may continuously monitor the channel quality of the local cell or the neighboring cell, and when the configured measurement event is satisfied (for example, the channel quality of the neighboring cell is higher than a certain threshold value + the channel quality of the local cell is lower than a certain threshold value), the terminal may generate a measurement report and report the measurement report to the base station, before reporting to the base station, the terminal in the NR-U cell needs to monitor a channel first, and if channel preemption is successful, the measurement report is considered to be sent in real time.

In one possible example, the sending, by the terminal, the measurement report to the first network device and notifying, by a preset manner, the first network device of the generation time of the measurement report includes: the terminal only sends the measurement report to the first network equipment, wherein the measurement report carries first indication information, and the first indication information is used for indicating the generation time of the measurement report.

The generation time indicated by the first indication information is used to indicate the generation time of the measurement report reported by the terminal, and the base station may select a target cell to send a handover request based on the generation time, for example, if the generation time of the measurement report is short, the network may consider that the measurement report has real-time performance, and perform handover preparation based on the measurement report, and if the generation time of the measurement report is long, the base station may select to reconfigure the terminal for measurement or perform handover preparation based on other auxiliary information of the terminal.

In one possible example, the terminal sends only the measurement report to the first network device, including: the terminal executes channel interception and preemption operation to obtain a preemption result; determining that the channel is successfully preempted and determining the generation time of the measurement report; carrying first indication information for indicating the generation time in the measurement report; and sending the measurement report carrying the first indication information to the first network equipment.

For an unlicensed frequency band, such as an LTE LAA unlicensed frequency band, in a channel access process of the frequency band, for downlink data transmission, in the unlicensed frequency band, a base station needs to perform channel interception and preemption operations according to an LBT mechanism, and in the LAA, a priority of channel access is determined by:

TABLE 1 (Table 15.1.1-1) channel Access priority Classification

Channel access priority classification (P)

Mp

Cwmin,p

Cwmax,p

Tmcot,p

Cwp

1	1	3	7	2ms	{3,7}
2	1	7	15	3ms	{7,15}
3	3	15	63	8or 10ms	{15,31,63}
4	7	15	1023	8or 10ms	{15,31,63,127,255,511,1023}

Where mp is related to the listening channel time for performing channel access. Specifically, the base station needs to perform channel sensing for a time Td, where Td is 16us + Mp × 9 us. Cwmin, p and Cwmax, p are related to the random listening channel time during the channel access process. Specifically, when the base station listens that the Td time channel is idle, it needs to listen to the channel N times again, and the time duration of each time is 9 us. Where N is a random number from 0 to CWp and Cwmin, p < CWp < Cwmax, p. Tmcot, p is the longest time that the base station occupies the channel after occupying the channel, and it has a relationship with the priority of the channel adopted by the base station, for example, if the priority is 1, the channel occupies the channel for 2ms at most after the channel interception is successful.

It can be seen that, in this example, since the terminal needs to perform channel interception and preemption based on the LBT mechanism before sending the measurement report, when the terminal fails to preempt a channel, the channel interception and preemption can be continued until the channel preemption succeeds, so that the processing duration of the channel interception and preemption operation is not fixed, and for the case that channel preemption succeeds once, the terminal can determine the first indication information according to the generation time of the measurement report, that is, inform the base station that the measurement report is reported in real time, thereby improving the reporting efficiency and accuracy of the measurement report.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; determining the time of actually generating the measurement report by the local terminal as the generation time; carrying first indication information for indicating the generation time in the measurement report; and sending the measurement report carrying the first indication information to the first network equipment.

The time when the local terminal actually generates the measurement report is the time when the terminal actually preempts the channel.

It can be seen that, in this example, since the terminal needs to perform channel interception and preemption based on the LBT mechanism before sending the measurement report, and the terminal can continue to intercept and preempt until the channel is successfully preempted when the channel is unsuccessfully preempted, the processing duration of the channel interception and preemption operation is not fixed, and there is a difference according to the actual execution situation, and the first indication information accurately indicates the generation time of the measurement report, so that the occurrence of the situation that the base station cannot accurately locate the generation time of the measurement report because the processing duration of the channel interception and preemption operation cannot be determined can be avoided, which is beneficial to improving the accuracy of reporting the measurement report by the terminal and improving the success rate of cell switching.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; judging whether the measurement configuration is consistent with the measurement result in the measurement report; judging that the measurement configuration is consistent with the measurement result, re-executing measurement to obtain a new measurement report, and determining the generation time of the new measurement report; carrying first indication information for indicating the generation time in the measurement report; and sending the new measurement report carrying the first indication information to the first network equipment.

It can be seen that, in this example, for a scenario in which the terminal succeeds in preemption for multiple times, the terminal may further detect the adaptability of the measurement configuration and the measurement result, and because the terminal may cause a large change in the terminal communication situation in the current time period due to movement and the like, the terminal obtains the latest measurement report by determining whether the measurement results of the measurement configuration and the measurement report are consistent and re-measuring the measurement result in the consistent situation, so that the problem of inaccurate measurement report due to processing delay can be avoided, and the accuracy of the measurement report and the success rate of cell switching can be improved.

Furthermore, the method further comprises: and the terminal judges that the measurement configuration is inconsistent with the measurement result and cancels the current measurement report. Namely, the environment of the current terminal is no longer suitable for cell measurement, and subsequent operation is not required to be continued, so that the intelligence and the power saving are improved.

In one possible example, the sending, by the terminal, the measurement report to the first network device and notifying, by a preset manner, the first network device of the generation time of the measurement report includes: and the terminal sends the measurement report and second indication information to the first network equipment, wherein the second indication information is used for indicating the generation time of the measurement report.

As can be seen, in this example, the terminal can indicate the generation time of the measurement report exclusively through the dedicated second indication information while reporting the measurement report, so that it is avoided that the base station cannot accurately know the generation time of the measurement report due to LBT processing delay of the terminal and other reasons, thereby accurately performing communication to complete cell handover and the like, and improving the reporting accuracy of the measurement report and the success rate of cell handover.

In one possible example, the terminal sends the measurement report and the second indication information to the first network device, including: the terminal executes channel interception and preemption operation to obtain a preemption result; determining that the channel preemption is successful in the preemption result, determining the generation time of the measurement report, and determining second indication information for indicating the generation time; and sending the measurement report and the second indication information to the first network equipment.

As can be seen, in this example, before reporting a measurement report, the terminal performs channel listening and preemption operation according to an LBT mechanism, and for a scene in which preemption is successful at one time, the terminal may simultaneously send the measurement report and second indication information, so that the base station determines the generation time of the current measurement report according to the second indication information, thereby performing communication in a corresponding time period, and improving the reporting accuracy of the measurement report and the cell switching success rate.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; determining the time of actually generating the measurement report by the local terminal as the generation time, and determining second indication information for indicating the generation time; and sending the measurement report and the second indication information to the first network equipment.

It can be seen that, in this example, since the terminal experiences channel preemption failure and the processing delay makes reporting of the measurement report no longer have real-time performance, the reporting event of the measurement report is accurately recorded through the second indication information, which can avoid the occurrence of a situation that the base station cannot accurately position the generated time due to the processing delay of the terminal, the base station can accurately position the time period in which the terminal preempts the channel resource according to the second indication information and perform effective communication in the corresponding time period, thereby improving the reporting accuracy of the measurement report and the success rate of cell switching.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; judging whether the measurement configuration is consistent with the measurement result in the measurement report; judging that the measurement configuration is consistent with the measurement result, re-executing measurement to obtain a new measurement report, determining the generation time of the new measurement report, and determining second indication information for indicating the generation time; and sending the measurement report and the second indication information to the first network equipment.

It can be seen that, in this example, the terminal may further detect the adaptability of the measurement configuration and the measurement result for a scenario in which the terminal succeeds in preemption for multiple times, and because the terminal may cause a large change in the local communication condition in the current time period due to movement and the like, the terminal obtains the latest measurement report by determining whether the measurement results of the measurement configuration and the measurement report are consistent and re-measuring the measurement result under the consistent condition, so that the problem of inaccurate measurement report due to processing delay can be avoided, and the accuracy of the measurement report and the success rate of cell switching can be improved.

In one possible example, the sending, by the terminal, the measurement report to the first network device and notifying, by a preset manner, the first network device of the generation time of the measurement report includes: the terminal obtains a measurement configuration from first network equipment, and executes measurement according to the measurement configuration to obtain a measurement report; sending only the measurement report to the first network device, where the measurement report is used for determining that the measurement report is reported in real time when the first network device receives the measurement report.

In one possible example, the terminal sends only the measurement report to the first network device, including: the terminal executes channel interception and preemption operation to obtain a preemption result; determining that the channel is successfully preempted and determining that the measurement report only carries the measurement result; sending only the measurement report to the first network device.

As can be seen, in this example, for a scenario in which a terminal succeeds in preempting a channel once, a base station may directly determine that a measurement report is sent in real time according to a situation that the base station only receives the measurement report by only sending the measurement report without any generated time indication information.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; and carrying first indication information in the measurement report, and sending the measurement report carrying the first indication information to the first network equipment, wherein the first indication information is used for indicating the generation time of the measurement report.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; and sending the measurement report and second indication information to the first network equipment, wherein the second indication information is used for indicating the generation time of the measurement report.

As can be seen, in this example, when the terminal reports the measurement report, the terminal can exclusively indicate the generation time of the measurement report through the dedicated second indication information, so that it can be avoided that the base station cannot accurately know the generation time of the measurement report due to the processing delay of the terminal and the like, and it is beneficial for the base station to accurately locate the time period when the terminal occupies the channel resource, thereby accurately performing communication to complete cell switching and the like, and improving the accuracy of reporting the measurement report and the success rate of cell switching.

In one possible example, the method further comprises: the terminal determines that the preemption result is channel preemption failure, and continues to execute channel interception and preemption operation until the channel preemption is successful; judging whether the measurement configuration is consistent with the measurement result in the measurement report; judging that the measurement configuration is consistent with the measurement result, re-executing measurement to obtain a new measurement report, and determining that the new measurement report only carries a new measurement result; sending only the new measurement report to the first network device.

In one possible example, the second indication information includes any one of: the system comprises Radio Resource Control (RRC) signaling, a media access control (MAC CE) unit and Uplink Control Information (UCI).

In one possible example, the first network device comprises a new wireless NR unlicensed NR-U cell, the second network device comprising any of: the system comprises an NR-U cell, an NR cell, a Long Term Evolution (LTE) cell and a primary and secondary cell PScell in a dual-connection scene.

In one possible example, the measurement report is for the first network device to: when detecting that the measurement result in the measurement report meets a preset switching condition, sending a switching request to second network equipment, receiving a switching response from the second network equipment, and sending a switching command to the terminal;

after the terminal sends the measurement report to the first network device and notifies the first network device of the generation time of the measurement report in a preset manner, the method further includes: and the terminal receives the switching command from the first network equipment and initiates a random access process to the second network equipment according to the switching command.

The following is further described with reference to specific scenario examples.

Referring to fig. 3A, fig. 3A is a flowchart illustrating a method for reporting a measurement report, which is applied to the exemplary communication system according to an embodiment of the present application, where the method includes:

in part 3a01, the source base station sends a measurement configuration to the terminal, the measurement configuration being used for cell measurements by the terminal.

In section 3a02, the terminal performs measurement according to the measurement configuration when the handover measurement event meets a preset condition to obtain a measurement result, and generates a measurement report to be reported according to the measurement result.

In the section 3a03, the terminal performs channel sensing and preemption operation based on a preset LBT mechanism to obtain a preemption result;

in part 3a04, when the preemption result is that the channel preemption is successful, the terminal determines the generation time of the measurement report; and carrying first indication information for indicating the generation time in the measurement report;

when the preemption result is that the channel preemption fails, the terminal continues to execute the channel interception and preemption operation until the channel preemption succeeds; determining the time of actually generating the measurement report by the local terminal as the generation time; and carrying first indication information used for indicating the generation time in the measurement report.

In part 3a05, the terminal sends only the measurement report carrying the first indication information to the source base station.

In part 3a06, the source base station sends a handover request to a target base station when detecting that the measurement result in the measurement report satisfies a preset handover condition.

At part 3a07, the target base station performs access control according to the handover request and sends a handover response to the source base station;

at part 3a08, the source base station receiving a handover response from the target base station;

in part 3a9, the source base station sends a handover command to the terminal.

In part 3a10, the terminal receives the handover command from the source base station, and initiates a random access procedure to the target base station according to the handover command.

It can be seen that, in this example, before the terminal sends the measurement report, the terminal performs channel interception and preemption operation, and regardless of the preemption result, the terminal accurately notifies the source base station in the form of the first indication information according to the actual generation time of the measurement report, so as to avoid the occurrence of the situation that the generation time of the measurement report cannot be accurately indicated due to channel preemption failure, which is beneficial to improving the accuracy of the indication of the measurement report and improving the success rate of cell handover.

Referring to fig. 3B, fig. 3B is a flowchart illustrating a method for reporting a measurement report according to an embodiment of the present application, where the method is applied to the exemplary communication system, and the method includes:

in part 3B01, the source base station sends a measurement configuration to the terminal, the measurement configuration being used for the terminal to perform measurements.

In section 3B02, the terminal performs measurement according to the measurement configuration when the handover measurement event satisfies a preset condition to obtain a measurement result, and generates a measurement report according to the measurement result.

In section 3B03, the terminal performs channel sensing and preemption operation according to a preset LBT mechanism to obtain a preemption result.

In part 3B04, when the preemption result is that the channel preemption is successful, the terminal determines a generation time of the measurement report and determines second indication information indicating the generation time.

When the preemption result is that the channel preemption fails, the terminal continues to execute the channel interception and preemption operation until the channel preemption succeeds; and determining the time when the local terminal actually generates the measurement report as the generation time, and determining second indication information for indicating the generation time.

In part 3B05, the terminal sends the measurement report and the second indication information to the source base station.

In part 3B06, the source base station sends a handover request to a target base station when detecting that the measurement result in the measurement report satisfies a preset handover condition.

In part 3B07, the target base station performs access control according to the handover request and sends a handover response to the source base station;

in part 3B08, the source base station receiving a handover response from the target base station;

in part 3B9, the source base station sends a handover command to the terminal.

In part 3B10, the terminal receives the handover command from the source base station, and initiates a random access procedure to the target base station according to the handover command.

It can be seen that, in this example, before the terminal sends the measurement report, the terminal performs channel interception and preemption operations, and regardless of the preemption result, the terminal accurately notifies the source base station in the form of the measurement report and the second indication information according to the actual generation time of the measurement report, thereby avoiding the occurrence of a situation that the generation time of the measurement report cannot be accurately indicated due to channel preemption failure, which is beneficial to improving the accuracy of the measurement report indication and improving the cell handover success rate.

Referring to fig. 3C, fig. 3C is a flowchart illustrating a method for reporting a measurement report according to an embodiment of the present application, where the method is applied to the exemplary communication system, and the method includes:

in part 3C01, the source base station sends a measurement configuration to the terminal, the measurement configuration being used for the terminal to perform measurements.

In the section 3C02, the terminal performs measurement according to the measurement configuration when the handover measurement event meets the preset condition to obtain a measurement result, and generates a measurement report to be reported according to the measurement result.

In section 3C03, the terminal performs channel sensing and preemption operation according to a preset LBT mechanism to obtain a preemption result.

In part 3C04, when the preemption result is that the channel preemption is successful, the terminal determines that the measurement report only carries the measurement result; transmitting only the measurement report to the source base station.

In the 3C05, when the preemption result is channel preemption failure, continuing to perform channel sensing and preemption operation until channel preemption succeeds; and carrying first indication information in the measurement report, and sending the measurement report carrying the first indication information to the source base station, wherein the first indication information is used for indicating the generation time of the measurement report.

In part 3C06, the source base station sends a handover request to a target base station when detecting that the measurement result in the measurement report satisfies a preset handover condition.

In part 3C07, the target base station performs access control according to the handover request and sends a handover response to the source base station;

at part 3C08, the source base station receiving a handover response from the target base station;

in part 3C9, the source base station sends a handover command to the terminal.

In part 3C10, the terminal receives the handover command from the source base station, and initiates a random access procedure to the target base station according to the handover command.

It can be seen that, in this example, before the terminal sends the measurement report, it may perform channel interception and preemption operations, and when channel preemption succeeds at a single time, it only sends the measurement report that does not include any indication information, and the base station may know, according to the measurement report, that the terminal generates the measurement report in real time, and when channel preemption fails until the channel preemption succeeds, the terminal indicates the actual generation time of the measurement report through the first indication information, which is beneficial to improving the accuracy of the measurement report indication and improving the cell handover success rate.
