Description

Methods of reporting measurement reports and related products Technical field

This application relates to the field of communication technology, and in particular to a method for reporting measurement reports and related products.

Background technique

Regarding the unlicensed NR-U frequency band in the New Radio NR system, the 3GPP RAN working group of the Third Generation Partnership Project agreed in December 2018 to establish the NR unlicensed working method (WID RP-182878). The goal of the project is to make NR work in unlicensed frequency bands, including the following work scenarios:

(1) Carrier aggregation scenario: PCell is a licensed spectrum, and SCells working on unlicensed spectrum are aggregated through carrier aggregation;

(2) Dual-connection working scenario: PCell is LTE licensed spectrum, PScell is NR unlicensed spectrum;

(3) Independent work scenario: NR works as an independent cell in unlicensed spectrum

Generally speaking, NR-U's working frequency band (Band) is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum, (for example, US5925-7125MHz, or European5925-6425MHz, etc.); on unlicensed spectrum, the design of NR-U should Ensure fairness with other systems that are already working on these unlicensed spectrums, such as wireless high-fidelity WiFi. The principle of fairness is that the impact of NR-U on systems that have been deployed on unlicensed spectrum (for example, WiFi) cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems on unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. The general energy detection mechanism is the LBT mechanism after listening first. The basic principle of this mechanism is that the base station or terminal (transmitting end) needs to listen for a period of time according to regulations before transmitting data on the unlicensed spectrum. If the result of the listening indicates that the channel is idle, the transmitting end can transmit data to the receiving end. If the listening result indicates that the channel is in an occupied state, the transmitting end needs to back off for a period of time according to regulations before continuing to listen to the channel until the channel listening result is idle before transmitting data to the receiving end.

For the terminal handover from the NR-U cell to other cells, the terminal needs to perform channel listening and preemption operations based on the LBT mechanism, and report the measurement report when the channel preemption is successful, so the channel listening and preemption operations will affect the real-time performance of the measurement report Make an impact.

detailed description

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

By way of example, FIG. 1A shows the wireless communication system involved in the present application. The wireless communication system 100 may work in a high frequency band, and may be the 5th Generation (5G) New Radio (NR) system, or Long Term Evolution (LTE) that will be evolved in the future. System, 5G NR and LTE joint networking system, etc. As shown in the figure, the wireless communication system 100 may include: one or more network devices 101, one or more terminals 103, and a core network device 105. Among them: the network device 101 can be a base station, which can be used to communicate with one or more terminals, and can also be used to communicate with one or more base stations with partial terminal functions (such as macro base stations and micro base stations, such as access Point, communication between). The base station can be the Base Transceiver Station (BTS) in the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, or it can be the Long Term Evolution (LTE) system Evolutional Node B (eNB), and the base station gNB in 5G and NR systems. In addition, the base station may also be an access point (Access Point, AP), a transmission node (Trans TRP), a central unit (Central Unit, CU) or other network entities, and may include some or all of the functions of the above network entities . The core network equipment 105 includes core network side equipment such as Serving GateWay (SGW). The terminal 103 may be distributed in the entire 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 (such as a smart phone), a mobile station, a mobile unit, an M2M terminal, a wireless unit, a remote unit, a user agent, or a user equipment ( User Equipment, UE) mobile client, etc.

It should be noted that the wireless communication system 100 shown in FIG. 1A is only used to describe the technical solution of the application more clearly, and does not constitute a limitation to the application. Those of ordinary skill in the art will know that with the evolution of the network architecture and new services In the emergence of scenarios, the technical solutions provided in this application are equally applicable to similar technical problems.

The related technologies involved in this application are introduced below.

Currently, as shown in FIG. 1B, the main process of the terminal for cell handover includes handover preparation, handover execution, and handover completion. Wherein, handover preparation means that the source base station configures the terminal for measurement report, and sends a handover request to the target base station based on the report result of the terminal. After the target base station agrees to the change request, it will configure a radio resource control (Radio Resource Control, RRC) message (for example: mobility control information, mobilityControlInformation) for the terminal, which includes resources for the random access channel (Random Access Channel, RACH) , Cell Radio Network Temporary Identifier (CellRadioNetworkTemporaryIdentifier, C-RNTI), target base station security algorithm, and target base station system messages. The handover execution includes the source base station forwarding the mobile control information to the terminal, and after receiving the handover command, the terminal initiates a random access procedure to the target base station. At the same time, the source base station will send the serial number status transfer (SNSTATUSTRANSFER) to the target base station, which is used to inform the target base station of the uplink packet data convergence protocol (Packet Data ConvergenceProtocol, PDCP) serial number (Serial Number, SN) reception status and downlink PDCP SN transmission status. The completion of handover includes when the terminal successfully accesses the target base station (random access is successful), the target base station will send a path switch request (PATH SWITCH REQ) terminal ST to request the mobility management entity (MME) to switch the downlink path, and path switch After the (path switch) is completed, the target base station will instruct the source base station to release the terminal context, and the handover is complete.

For some special scenarios, such as the terminal moving at high speed or high frequency conditions, frequent handovers are required. Conditional handover can avoid the problem that the handover preparation time is too long, which causes the terminal to switch too late. As shown in Figure 1C, the handover command HO command can be configured for the terminal in advance. On the other hand, for the high-speed rail scenario, the terminal's operating trajectory is specific, so the base station can allocate the target base station to the terminal in advance, and the HO command includes the condition for triggering the terminal to switch. When the allocated condition is met, The terminal initiates an access request to the target base station. At present, the 3GPP RAN2#104 meeting has agreed to conditional handover, and supports configuring multiple target cells in the conditional handover HO command. The terminal determines which target cell to access based on the configured condition.

Dual-Connectivity (DC) is an important technology introduced in 3GPP Release-12. Through dual-connection technology, LTE macro stations and small stations can use the existing non-ideal backhaul X2 interface to implement carrier aggregation, thereby providing users with a higher rate. A terminal that supports dual connectivity can connect to two LTE base stations at the same time, increasing the throughput of a single user. During the deployment of the 5G network, the 5G cell can be used as a macro-coverage independent networking, or as a small cell to enhance the coverage and capacity of the existing LTE network. 3GPP Release-14 defines the dual-connection technology of LTE and 5G based on the LTE dual-connection technology. LTE/5G dual connectivity is a key technology for operators to achieve LTE and 5G converged networking and flexible deployment scenarios. In the early stage of 5G, rapid deployment can be achieved based on the existing LTE core network, and in the later stage, comprehensive network coverage can be achieved through the joint networking of LTE and 5G, which improves the radio resource utilization of the entire network system, reduces system switching delays, and increases users And system performance.

In the 3GPP mobility enhancement subject, an optimization method for reducing the interruption time during handover is proposed, including the following two architectures: 1. DC based HO, during handover, first add the target base station as SN, and then use the role change message Let Lai change the SN (target base station) to MN, and finally release the source base station to reduce the interruption time during handover. 2. eMBB based HO, based on the existing handover process, when the UE receives the HO command, it continues to maintain the connection with the source base station and initiates random access to the target base station. The connection of the source base station is not released until the UE and the target base station are connected. .

At present, for the terminal handover from the NR-U cell to other cells, the terminal needs to perform channel listening and preemption operations based on the LBT mechanism, and report the measurement report when the channel preemption is successful. Therefore, the channel listening and preemption operations will affect the measurement report. Real-time affects. The terminal sends a measurement report to the base station after one or more channel preemption failures until the channel preemption succeeds. At this time, the base station cannot accurately know the generation time of the measurement report, resulting in handover failure.

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

Please refer to FIG. 2. FIG. 2 is a method for reporting a measurement report according to an embodiment of the present application, which is applied to the above example communication system, and the method includes:

In part 201, the terminal obtains the measurement configuration from the first network device, performs measurement according to the measurement configuration to obtain a measurement report;

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

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.

Wherein, the preset mode is a rule preset by the terminal and the network device, which specifically includes a first indication information indication, a second indication information indication, a hiding indication, etc., which are not uniquely limited here.

Wherein, the generation time of the measurement report specifically refers to the time when the terminal successfully seizes the channel. In specific implementation, after receiving the measurement configuration, the terminal will continue to monitor the channel quality of the cell or neighboring cells, when the configured measurement event is met (for example, the channel quality of the neighboring cell is higher than a certain threshold + the channel quality of the cell is lower than a certain threshold) The terminal will generate a measurement report and report it to the base station. Before reporting to the base station, the terminal of the NR-U cell needs to monitor the channel first. If the channel is successfully seized, the measurement report is considered to be sent in real time.

It can be seen that in this embodiment of the application, the terminal first obtains the measurement configuration from the first network device, performs measurement according to the measurement configuration to obtain a measurement report, and secondly, sends the measurement report to the first network device and informs the first network in a preset manner The generation time of the equipment measurement report. It can be seen that since the terminal can notify the first network device of the generation time of the measurement report in a preset manner while sending the measurement report, this can prevent the terminal from being unable to accurately determine the generation time of the reported measurement report due to channel preemption failure. It is beneficial to ensure the timeliness of the measurement report reported by the terminal and improve the success rate of cell handover.

In a possible example, the terminal sending the measurement report to the first network device and notifying the first network device of the generation time of the measurement report in a preset manner includes: the terminal sends the measurement report to the The first network device only sends the measurement report, where the measurement report carries first indication information, and the first indication information is used to indicate 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. The base station can select the target cell to send the handover request based on the generation time. For example, if the generation time of the measurement report is short, the network can The measurement report is considered to be real-time, and handover preparations are made based on the measurement report. If the measurement report generation time is longer than the receiving time, the base station can choose to reconfigure the terminal for measurement or perform handover preparations based on other auxiliary information of the terminal .

In a possible example, the terminal sending only the measurement report to the first network device includes: the terminal performs channel sensing and preemption operations to obtain a preemption result; determining that the preemption result is a successful channel preemption , Determining the generation time of the measurement report; carrying first indication information for indicating the generation time in the measurement report; sending only the measurement carrying the first indication information to the first network device report.

Among them, for unlicensed frequency bands, such as LTE LAA unlicensed frequency bands, in the channel access process of this frequency band, for downlink data transmission, in the unlicensed frequency band, the base station needs to perform channel listening and preemption operations according to the LBT mechanism. In LAA , The priority of channel access is determined by the following table:

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}

The mp is related to the listening channel time for performing channel access. Specifically, the base station needs to perform channel sensing for Td time first, where Td=16us+Mp×9us. Cwmin,p and Cwmax,p are related to the random listening channel time during channel access. Specifically, when the base station listens to the channel for Td time and is idle, it needs to listen to the channel again N times, each with a duration of 9 us. Where N is a random number from 0 to CWp, and Cwmin,p<=CWp<=Cwmax,p. Tmcot,p is the longest time for the base station to occupy the channel after it has seized the channel. It is related to the channel priority adopted by the base station. For example, if the priority is 1, the channel will be occupied for 2ms at most after the channel is successfully monitored.

It can be seen that in this example, since the terminal needs to perform channel listening and preemption based on the LBT mechanism before sending the measurement report, if the terminal fails to seize the channel, it can continue to listen and preempt until the channel is successfully seized, so the channel listening and preemption operations The processing time is not fixed. For the situation where the channel is successfully seized 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, improving the efficiency and accuracy of reporting the measurement report .

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel listening and preemption operations until the channel preemption succeeds; determining the time when the local end actually generates the measurement report Is the generation time; carrying first indication information for indicating the generation time in the measurement report; and sending only the measurement report carrying the first indication information to the first network device.

Wherein, the time when the local terminal actually generates the measurement report refers to the time when the terminal actually successfully seizes the channel.

It can be seen that in this example, since the terminal needs to perform channel listening and preemption based on the LBT mechanism before sending the measurement report, if the terminal fails to seize the channel, it can continue to listen and preempt until the channel is successfully seized, so the channel listening and preemption operations The processing time is not fixed and will vary according to the actual implementation. The first indication information accurately indicates the generation time of the measurement report, which can prevent the base station from being unable to determine the processing time of channel listening and preemption operations. Accurately locating the occurrence of the generation time of the measurement report is beneficial to improve the accuracy of the measurement report reported by the terminal and improve the success rate of cell handover.

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel listening and preemption operations until the channel preemption succeeds; judging that the measurement configuration and the measurement report are Whether the measurement results are consistent with each other; it is determined that the measurement configuration is consistent with the measurement result, the measurement is performed again to obtain a new measurement report, and the generation time of the new measurement report is determined; the measurement report is used to indicate all The first indication information of the generation time; and only the new measurement report carrying the first indication information is sent to the first network device.

It can be seen that, in this example, the terminal can further detect the adaptability of the measurement configuration and the measurement result for the scenario where the terminal is successful after multiple preemptions, because the terminal's communication situation may change greatly in the current period due to reasons such as movement, so By judging whether the measurement configuration of the measurement configuration is consistent with the measurement results of the measurement report, and re-measurement under consistent conditions to obtain the latest measurement report, this can avoid the problem of inaccurate measurement reports caused by processing delays, which is beneficial to improve the accuracy of measurement reports And the success rate of cell handover.

In addition, the method further includes: the terminal determines that the measurement configuration is inconsistent with the measurement result, and cancels this measurement report. That is, the current terminal environment is no longer suitable for cell measurement, and subsequent operations do not need to be continued, which improves intelligence and saves power.

In a possible example, the terminal sending the measurement report to the first network device and notifying the first network device of the generation time of the measurement report in a preset manner includes: the terminal sends the measurement report to the The first network device sends the measurement report and second indication information, where the second indication information is used to indicate the generation time of the measurement report.

It can be seen that in this example, since the terminal is reporting the measurement report at the same time, it can use the dedicated second indication information to exclusively indicate the generation time of the measurement report, which can prevent the base station from being unable to accurately obtain the measurement report due to the terminal's LBT processing delay and other reasons. The generation time, so as to accurately perform communication to complete cell switching, etc., improve the accuracy of measurement report reporting and the success rate of cell switching.

In a possible example, sending the measurement report and second indication information by the terminal to the first network device includes: the terminal performs channel sensing and preemption operations to obtain a preemption result; and determining the preemption result To successfully seize the channel, determine the generation time of the measurement report and determine the second indication information used to indicate the generation time; send the measurement report and the second indication information to the first network device.

It can be seen that in this example, the terminal will perform channel listening and preemption operations according to the LBT mechanism before reporting the measurement report. For a scenario where preemption is successful, the terminal can send the measurement report and the second indication information at the same time, so that the base station can follow the first The second indication information determines the generation time of the current measurement report, so as to communicate in the corresponding time period, and improve the accuracy of measurement report reporting and the success rate of cell handover.

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel listening and preemption operations until the channel preemption succeeds; determining the time when the local end actually generates the measurement report Is the generation time and determining second indication information for indicating the generation time; sending the measurement report and the second indication information to the first network device.

It can be seen that, in this example, because the terminal has failed to seize the channel, the processing delay makes the reporting of the measurement report no longer real-time. Therefore, the second indication information can accurately record the reporting event of the measurement report, which can avoid the processing delay of the base station due to the terminal. Sometimes it is impossible to accurately locate the generation time. The base station can accurately locate the time period during which the terminal seizes channel resources according to the second indication information, and conduct effective communication within the corresponding time period, thereby improving the accuracy of measurement report reporting and the success rate of cell handover.

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel listening and preemption operations until the channel preemption succeeds; judging that the measurement configuration and the measurement report are Whether the measurement results of the new measurement report are consistent; determine that the measurement configuration is consistent with the measurement result, re-execute the measurement to obtain a new measurement report, determine the generation time of the new measurement report, and determine the first time indicating the generation time Two indication information: sending the measurement report and the second indication information to the first network device.

It can be seen that, in this example, the terminal can further detect the adaptability of the measurement configuration and the measurement result for the scenario where the terminal is successful for multiple preemptions, because the terminal may have a large change in the communication situation of the local terminal in the current period due to reasons such as movement. Therefore, by judging whether the measurement configuration is consistent with the measurement results of the measurement report, and re-measurement under the same condition, the latest measurement report can be obtained. This can avoid the problem of inaccurate measurement report caused by processing delay, which is beneficial to improve the measurement report. Accuracy and success rate of cell handover.

In addition, the method further includes: the terminal determines that the measurement configuration is inconsistent with the measurement result, and cancels this measurement report. That is, the current terminal environment is no longer suitable for cell measurement, and subsequent operations do not need to be continued, which improves intelligence and saves power.

In a possible example, the terminal sending the measurement report to the first network device and notifying the first network device of the generation time of the measurement report in a preset manner includes: the terminal obtains information from the first network device The measurement configuration of a network device is executed according to the measurement configuration to obtain a measurement report; only the measurement report is sent to the first network device, wherein the measurement report is used when the first network device receives all the measurement reports. When the measurement report is described, it is determined that the measurement report is reported in real time.

In a possible example, the terminal sending only the measurement report to the first network device includes: the terminal performs channel sensing and preemption operations to obtain a preemption result; determining that the preemption result is a successful channel preemption , It is determined that the measurement report only carries the measurement result; only the measurement report is sent to the first network device.

It can be seen that in this example, for a scenario where the terminal succeeds in seizing the channel once, it can send only a measurement report without any generation time indication information, and the base station directly determines that the measurement report is sent in real time according to the situation that the local terminal only receives the measurement report. Yes, this method does not require any instructions, it is simple and efficient.

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel sensing and preemption operations until the channel preemption succeeds; carrying first indication information in the measurement report And send a measurement report carrying the first indication information to the first network device, where the first indication information is used to indicate 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. The base station can select the target cell to send the handover request based on the generation time. For example, if the generation time of the measurement report is short, the network can The measurement report is considered to be real-time, and handover preparations are made based on the measurement report. If the measurement report generation time is longer than the receiving time, the base station can choose to reconfigure the terminal for measurement or perform handover preparations based on other auxiliary information of the terminal .

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel listening and preemption operations until the channel preemption succeeds; sending the measurement to the first network device Report and second indication information, where the second indication information is used to indicate the generation time of the measurement report.

It can be seen that in this example, since the terminal is reporting the measurement report at the same time, it can use the dedicated second indication information to exclusively indicate the generation time of the measurement report, which can prevent the base station from being unable to accurately obtain the measurement report due to the processing delay of the terminal. The generation time is conducive to the base station to accurately locate the time period when the terminal occupies the channel resources, so as to accurately perform communication to complete cell switching, etc., and improve the accuracy of measurement report reporting and the success rate of cell switching.

In a possible example, the method further includes: the terminal determines that the preemption result is a channel preemption failure, and continues to perform channel listening and preemption operations until the channel preemption succeeds; judging that the measurement configuration and the measurement report are Whether the measurement results are consistent with the measurement results; it is determined that the measurement configuration is consistent with the measurement results, the measurement is performed again to obtain a new measurement report, and it is determined that the new measurement report only carries the new measurement results; Send the new measurement report.

It can be seen that, in this example, the terminal can further detect the adaptability of the measurement configuration and the measurement result for the scenario where the terminal is successful for multiple preemptions, because the terminal may have a large change in the communication situation of the local terminal in the current period due to reasons such as movement. Therefore, by judging whether the measurement configuration is consistent with the measurement results of the measurement report, and re-measurement under the same condition, the latest measurement report can be obtained. This can avoid the problem of inaccurate measurement report caused by processing delay, which is beneficial to improve the measurement report. Accuracy and success rate of cell handover.

In addition, the method further includes: the terminal determines that the measurement configuration is inconsistent with the measurement result, and cancels this measurement report. That is, the current terminal environment is no longer suitable for cell measurement, and subsequent operations do not need to be continued, which improves intelligence and saves power.

In a possible example, the second indication information includes any one of the following: radio resource control RRC signaling, medium access control unit MAC CE, and uplink control information UCI.

In a possible example, the first network device includes a new wireless NR unlicensed NR-U cell, and the second network device includes any one of the following: NR-U cell, NR cell, Long Term Evolution LTE cell, and Primary and secondary cells PScell in dual connectivity scenarios.

In a possible example, the measurement report is used by the first network device to perform the following operations: when it is detected that the measurement result in the measurement report satisfies a preset handover condition, sending a handover request to the second network device, And receiving a handover response from the second network device, and sending a handover 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: the terminal receives from the first network device The switching command of a network device initiates a random access procedure to the second network device according to the switching command.

The following is a further explanation in conjunction with specific scenario examples.

Please refer to FIG. 3A. FIG. 3A is a method for reporting a measurement report according to an embodiment of the present application, which is applied to the above example communication system, and the method includes:

In part 3A01, the source base station sends a measurement configuration to the terminal, and the measurement configuration is used for the terminal to perform cell measurement.

In part 3A02, according to the measurement configuration, the terminal performs measurement 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 part 3A03, the terminal performs channel listening and preemption operations based on the preset LBT mechanism, and obtains the preemption result;

In part 3A04, when the preemption result is successful channel preemption, the terminal determines the generation time of the measurement report; and the measurement report carries first indication information for indicating the generation time;

When the preemption result is failure to seize the channel, the terminal continues to perform channel sensing and preemption operations until the seizure of the channel succeeds; and determines that the time when the local terminal actually generates the measurement report is the generation time; and The report carries first indication information used to indicate the generation time.

In part 3A05, the terminal only sends 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 the target base station when detecting that the measurement result in the measurement report meets the preset handover condition.

In part 3A07, the target base station performs access control according to the handover request, and sends a handover response to the source base station;

In part 3A08, the source base station receives the 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, the terminal will perform channel listening and preemption operations before sending the measurement report. Regardless of the preemption result, the terminal will accurately notify the source base station in the form of the first indication information according to the actual generation time of the measurement report. The occurrence of a situation where the generation time of the measurement report cannot be accurately indicated due to the failure of channel preemption, which is beneficial to improve the accuracy of the measurement report indication and the success rate of cell handover.
