cross reference

This invention requires the priority of the Chinese patent application submitted to the China Patent Office on May 25, 2022, with the application number 202210577191.2 and the invention name "Measurement Report Reporting Method, Device, Terminal and Network Side Equipment". All the application's The contents are incorporated herein by reference.

Technical field

This application belongs to the field of wireless communication technology, and specifically relates to a measurement report reporting method, device, terminal and network side equipment.

Background technique

Relay technology in wireless communication systems adds one or more relay nodes between the base station and the terminal (User Equipment, UE), which is responsible for forwarding wireless signals one or more times, that is, wireless The signal has to go through multiple hops to reach the terminal. Wireless relay technology can not only expand cell coverage and make up for cell coverage blind spots, but can also increase cell capacity through spatial resource reuse. For indoor coverage, Relay technology can also overcome penetration loss and improve indoor coverage quality.

Taking the simpler two-hop relay as an example, wireless relay divides a base station-terminal link into two links: base station-relay station and relay station-terminal, thereby having the opportunity to replace a poor quality link with two links. A better quality link to obtain higher link capacity and better coverage. For example, in a typical UE-to-Network scenario, the remote terminal (Remote UE) needs to transmit data with the network side, but due to poor coverage, the relay terminal (Relay UE) is found. Among them, the Uu interface is between Relay UE and the base station, and the sidelink (SL) interface (also called PC5 interface) is between Relay UE and Remote UE.

In related technologies, between the terminal and the network side, one situation is to establish a direct path (Direct path), that is, the terminal establishes a wireless link with the base station through the Uu air interface, and the other situation is an indirect path (Indirect path). That is, the terminal (remote UE) establishes a wireless link with the base station through another terminal (relay UE) and the air interface of the other terminal. When the terminal establishes a non-direct path, the network needs The control terminal can perform the relay UE discovery process only when the link condition is poor enough.

However, in some cases, in order to obtain better transmission quality, the terminal may need to establish a direct path and an indirect path at the same time, that is, the terminal communicates with the network side through multiple paths. Through multi-path data transmission technology, the network side transmits data for the same target device through multiple associated UEs. In a multi-path data transmission scenario based on multiple UEs, there is a certain correlation between multiple UEs when providing business services. However, the current measurement configuration and reporting are configured based on a single UE, and each UE reports according to its own measurement The configuration is reported, resulting in low communication performance. For example, the network side device may cause multipath data transmission to fail after handover or cell reselection for one or more of the associated multiple UEs.

Figure 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a second terminal 11, a network side device 12 and a first terminal 13. In the embodiment of this application, the first terminal 13 and the second terminal 11 can communicate through the PC5 (secondary link) interface, and the second terminal 11 and the first terminal 13 can communicate with the network side device 12 through the Uu interface. communication.

The second terminal 11 may also be called a relay terminal device or a relay user terminal (User Equipment, UE), and the first terminal 13 may also be called a first terminal device or a remote terminal (r emote) UE, the second terminal 11 and the first terminal 13 may be a mobile phone, a tablet computer (Tablet Per sonal Computer), a laptop computer (Laptop Computer), or a notebook computer or a personal digital assistant (Personal Digital Assistant, PDA) , handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted equipment (VehicleUser Equipment, VUE) , Pedestrian User Equipment (PUE) and other terminal-side devices.

In some scenarios, in order to obtain better transmission quality, the network side device may transmit data for the same target object through multiple terminals (User Equipment, UE). The target object may be one of the multiple UEs as shown in the figure. As shown in 2a. Alternatively, as shown in Figure 2b, the target object may also be a third device unit connected to the plurality of UEs. The multiple UEs are called associated multiple UEs, in which each UE can establish a wireless connection with the network and provide an optional transmission path. The connection between the two UEs can be based on PC5 technology, or it can be based on other technologies, such as Universal Serial Bus (Universal Serial Bus, USB) connection or WiFi connection. During the process of transmitting data to the target device, data can be transmitted between the target object and the network side device through multiple paths to enhance the robustness of data transmission. For example, the following data transmission can be used between the target object and the network side device:

(1) Offload transmission: part of the data of the same service is transmitted through one associated multi-UE, and other part of the data is transmitted through another associated multi-UE;

(2) Repeated transmission: One copy of the data of the same service is transmitted through one associated multi-UE, and another copy is transmitted through another associated multi-UE;

(3) Backup transmission: The data of the same service is only sent to the target device through one associated multi-UE. When the wireless channel quality of the associated multi-UE deteriorates or cannot meet the data transmission quality of service (QoS) requirements, or otherwise When the wireless channel quality of one associated multi-UE becomes better, it is switched to another associated multi-UE for data transmission of the service.

Through multi-path data transmission technology, network-side devices can transmit data for the same target device by associating multiple UEs. In some scenarios, multiple associated UEs (the multiple UEs may be called UEs in an aggregation state) need to move with the target device. When the network side device determines the serving base station for each UE in the aggregation state, if it is determined based on only one of the associated UE's own measurement reports, it may cause the associated UE to switch or cell selection to reselect the base station/cell associated with the UE. Out-of-synchronization and/or inconsistency results in the inability to transmit one or more aggregated data, making data transmission less robust. Therefore, in a multi-path data transmission scenario based on multiple UEs, when multiple UEs provide business services, there is an association relationship (multiple UEs can be called multiple associated UEs), so the base station is required to make a switch to associate multiple UEs. When making the decision, the measurement results of all associated multiple UEs need to be considered. However, the existing measurement configuration and reporting are configured based on a single UE, and each UE reports according to the measurement reporting configuration. When the base station receives the measurement configuration of an associated UE, it is likely that there are no valid measurement reporting values of other associated UEs, and it is unable to determine the association handover of multiple associated UEs, for example, whether it is necessary to handover to the same target cell or target NR together. Node (NR Node B, gN B). In response to the above problems, embodiments of the present application provide a method for reporting measurement reports. In the scenario of associated movement of multiple associated UEs, the correlation characteristics of measurement reporting triggering and measurement report reporting between multiple associated UEs are considered. Implement association mobility management between multiple associated UEs to ensure the reliability and continuity of services provided by multiple associated UEs.

The measurement report reporting scheme provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

FIG. 3 shows a schematic flowchart of a method for reporting a measurement report in an embodiment of the present application. The method 300 can be executed by the first terminal. In other words, the method may be performed by software or hardware installed on the first terminal. As shown in Figure 3, the method may include the following steps.

S310: The first terminal obtains the measurement result of the first terminal.

Wherein, the first terminal may be one terminal among multiple terminals associated with multi-path data transmission.

For example, the first terminal can perform measurements according to the measurement configuration information configured by the network side device and obtain the measurement results.

S312: The first terminal jointly reports a measurement report with a second terminal, where the second terminal is a terminal among the plurality of terminals except the first terminal.

For example, when the measurement result triggers a first measurement reporting event, the first terminal may jointly report a measurement report with the second terminal, where the first measurement reporting event may be a measurement reporting event configured by the network side device for the first terminal, using To instruct the first terminal under what circumstances to report the measurement results. The first measurement reporting event includes but is not limited to at least one of event A1, event A2, and event A4 defined in the related art.

In this embodiment of the present application, the first terminal may be a primary terminal in multipath data transmission, for example, UE1 in Figures 2a and 2b, or it may be a secondary terminal in multipath data transmission, for example, Figures 2a and 2b UE2 in 2b may also be the terminal with the best wireless channel quality among multiple terminals associated with multi-path data transmission. For example, multiple terminals associated with multi-path data transmission can interact with each other regarding their wireless channel quality. When the terminal with the best channel quality triggers the first measurement reporting event, it jointly reports the measurement report with other terminals associated with the multipath data transmission. Alternatively, the first terminal may also be a remote terminal (remote UE) among multiple terminals associated with multipath data transmission.

In this embodiment of the present application, the second terminal may be a secondary terminal in multipath data transmission, for example, UE2 in Figures 2a and 2b, or it may be a primary terminal in multipath data transmission, for example, Figures 2a and 2b UE1 in 2b may alternatively be the terminal with the best wireless channel quality among multiple terminals associated with multipath data transmission. For example, multiple terminals associated with multipath data transmission may interact with each other regarding their wireless channel quality. The first terminal When it is determined that the first measurement reporting event is triggered, the terminal with the best wireless channel quality among multiple terminals associated with joint multipath data transmission reports a measurement report. Alternatively, the second terminal may also be a relay terminal (relay U E) among multiple terminals associated with multipath data transmission.

In this embodiment of the present application, any connection technology may be used between the first terminal and the second terminal, such as secondary link connection (SL link), secondary link relay (SL-relay), WiFi, USB, Bluetooth, cable, etc.

In this embodiment of the present application, when the first terminal associated with multi-path data transmission determines that the first measurement reporting event is triggered, it jointly reports the measurement report with the second terminal associated with multi-path data transmission, so that the network side can obtain the multi-path Measurement reports of multiple terminals associated with data transmission can then be used to perform mobility management based on the measurement reports of the multiple terminals. This can ensure that after handover or cell reselection is performed on one or more of the associated multiple UEs, The normal transmission of multipath data ensures the reliability and continuity of services provided by multiple associated UEs.

In a possible implementation, the first terminal and the second terminal jointly reporting the measurement report may include the following steps:

S3120, the first terminal obtains the measurement result of the second terminal;

S3122. The first terminal sends a measurement report to the serving base station, where the measurement report includes the measurement result of the first terminal and the measurement result of the second terminal.

In the above possible implementation manner, the first terminal obtains the measurement result of the second terminal, and sends a measurement report to the serving base station when it is determined that the first measurement reporting event is triggered.

In a possible implementation, the first terminal may obtain a measurement report from the second terminal after determining to trigger the first measurement reporting event based on the measurement results, or the second terminal may also determine to trigger the second measurement reporting event. (that is, when the network side configures a measurement reporting event for the second terminal), the measurement is performed and the measurement result is sent to the first terminal. The first terminal performs the measurement according to the measurement result of the first terminal or based on the measurement result of the first terminal. If the measurement result of the second terminal determines that the first measurement reporting event is triggered, a measurement report is sent to the serving base station.

In a possible implementation, the measurement report reported by the first terminal in S3122 may include at least one of the following:

(1) The measurement results of the serving cell of the first terminal;

(2) Measurement results of one or more neighboring cells of the first terminal;

(3) The measurement results of the serving cell of the second terminal;

(4) Measurement results of one or more neighboring cells of the second terminal;

(5) Measurement results of wireless link quality between the first terminal and the second terminal.

In a possible implementation, the measurement report may also include an identifier of the second terminal.

In a possible implementation, the measurement result of the second terminal includes at least one of the following: the measurement result of the preferred neighboring cell of the first terminal, and the measurement result of the preferred neighboring cell of the first terminal. Measurement results of cells with the same base station. Wherein, the preferred neighboring cell may be a preferred neighboring cell determined based on frequency priority group and/or wireless signal quality. Through this possible implementation, the network side device can obtain the measurement results of the second terminal on the preferred neighbor cell of the first terminal and/or the cell of the same base station as the preferred neighbor cell of the first terminal, so that the network side device can obtain the measurement results of the second terminal on the preferred neighbor cell of the first terminal. During the performance management process, determine whether to switch or reselect the second terminal to the first terminal based on the measurement results of the second terminal on the preferred neighboring cell of the first terminal and/or the cell of the same base station as the preferred neighboring cell of the first terminal. The preferred neighbor cell to be switched by a terminal and/or the cell of the same base station as the preferred neighbor cell of the first terminal ensures that the base station and/or cell of the first terminal and the second terminal are consistent and the continuity of multipath data transmission is ensured.

For example, when the first terminal determines that the first measurement reporting event is triggered, based on its own measurement results, the first terminal can send the identifier of its preferred neighboring cell to the second terminal. Based on the identifier, the second terminal can perform the measurement on the second terminal. The corresponding preferred neighboring cells and/or the preferred neighboring cells and the cells of the same base station are measured, and the measurement results of the preferred neighboring cells and/or the preferred neighboring cells and the cells of the same base station are obtained.

Alternatively, when the first terminal determines that the first measurement reporting event is triggered, based on its own measurement results, the first terminal may send one or more of the cells, frequencies, measurement quantities, etc. that the first terminal expects to measure, to the second terminal. , the second terminal performs measurements based on this information, and prior to sending the corresponding measurement results to the first terminal, provides the measurement results of the cell that is expected to be measured.

In a possible implementation, before S310, the method may further include: the first terminal obtains configuration information of the associated measurement report from its serving base station, where the first configuration information includes at least one of the following: Identifier, first indication information, wherein the first indication information indicates that associated measurement is enabled. That is to say, the first instruction information instructs the first terminal to perform associated measurement, that is, instructs the first terminal to jointly report a measurement report with the second terminal. According to the identifier of the second terminal and the first indication information in the first configuration information, the first terminal may determine to jointly report the measurement report with the second terminal when the first measurement reporting event is triggered.

In a possible implementation, the first terminal and the second terminal jointly report a measurement report, including:

S3121: The first terminal sends a first measurement report to the serving base station, where the first measurement report includes the measurement result of the first terminal;

S3123. The first terminal sends second instruction information to the second terminal, where the second instruction information is used to instruct the second terminal to send a second measurement report, and the second measurement report includes the Measurement results of the second terminal.

In the above possible implementation manner, when the first terminal determines to trigger the first measurement reporting event according to the measurement result of the first terminal, it sends the first measurement report to the serving base station, wherein the first measurement report includes the first measurement report. The measurement result of one terminal is sent to the second terminal, and the second instruction information is sent to instruct the second terminal to send a second measurement report. The second measurement report includes the measurement result of the second terminal. In this possible implementation, the measurement report reported by the first terminal jointly with the second terminal includes the first measurement report and the second measurement report.

Through the above possible implementation manner, after the measurement reporting event of one terminal among multiple terminals associated with multipath data transmission is triggered, indication information can be sent to other associated terminals, instructing other associated terminals to perform measurements and report, thereby making the network The side device can obtain measurement results of associated multiple terminals for mobility management.

In a possible implementation, the second indication information includes but is not limited to at least one of the following:

(1) The identification information reported by measurement includes one of the following: the measurement object identifier (Measurement Object Identifier, MO ID) of the first terminal and the measurement object identifier of the second terminal;

(2) Identification information of the neighboring cell to be measured; for example, the identification information of the neighboring cell to be measured may be the identification information of the neighboring cell that the first terminal expects to measure, for example, the identification information of the preferred cell of the first terminal.

(3) Carrier frequency to be measured. For example, the carrier frequency to be measured may be a carrier frequency that the first terminal expects to measure, for example, a preferred carrier frequency of the first terminal.

In a possible implementation, the first terminal and the second terminal jointly reporting the measurement report may include: S3124. In the case where the measurement result of the first terminal triggers the first measurement reporting event, A terminal sends the indication information of the first measurement reporting event and/or the measurement result of the first terminal to the second terminal, and the second terminal reports the information.

For example, when multiple terminals associated with multipath data transmission include a primary UE and a secondary UE, when a measurement reporting event of the secondary UE is triggered, the secondary UE may report the measurement reporting event and measurement results to the primary UE, and the primary UE will The UE determines whether to report to the serving base station. Among them, the primary UE may send the measurement results of the secondary UE together with its own measurement report to the serving base station. Alternatively, the primary UE sends its own measurement report to the secondary UE, and the secondary UE sends both the received measurement value of the primary UE and its own measurement result to the serving base station.

In a possible implementation, before S312, the method may further include: the first terminal receiving the indication information of the second measurement reporting event sent by the second terminal and the measurement result of the second terminal. In this possible implementation, after receiving the second measurement reporting event of the second terminal and the measurement result of the second terminal, the first terminal reports the measurement report to the serving base station. For example, the first terminal may receive the second measurement report of the second terminal. After measuring the reporting event and the measurement result of the second terminal, if the measurement result of the first terminal triggers the first measurement reporting event, a measurement report is reported to the serving base station, and the measurement report includes the measurement result of the first terminal and Therefore, when both the first terminal and the second terminal meet the measurement reporting events, an associated measurement report can be reported to avoid unnecessary reporting of measurement results.

In the above possible implementation manner, optionally, the first terminal jointly reports a measurement report with a second terminal, including: S3124, the first terminal sends a measurement report to the serving base station, wherein the measurement report includes the second The measurement results of the terminal and the measurement results obtained by the first terminal measurement.

In the above possible implementation manner, optionally, the measurement result of the second terminal may include: the measurement result of a neighboring cell of the second terminal.

For example, when multiple terminals associated with multipath data transmission include a primary UE and a secondary UE, the primary UE receives the measurement results of any other UE's neighboring cells and determines whether to trigger a measurement report based on the measurement results of its own cell. event. For example, when measuring a same-frequency cell, the wireless channel quality of the neighboring cell measured by any UE (such as Synchronization Signal and PBCH (Physical broadcast channel) block-Reference Signal Received Power, SSB- If the RSRP) is higher than the wireless channel quality of the serving cell measured by the primary UE by a preconfigured offset, it is determined to trigger an intra-frequency measurement reporting event. The any UE may be a secondary UE or It may be other UEs except the secondary UE.

The above-mentioned first terminal may also be the UE with the best wireless channel quality among the multiple associated UEs. For example, the UE with the best wireless channel quality among multiple associated UEs decides whether to trigger a measurement report event, that is, the UE with the best wireless channel quality determines by itself whether to trigger a measurement report. Or the master UE among the multiple associated UEs determines whether to trigger a measurement report based on the measurement report of the UE with the best wireless channel quality among the multiple associated UEs. That is, the UE with the best wireless quality reports the measurement results to the main UE, and the main UE decides whether to trigger the measurement report.

In one or more possible implementations, the measurement report reported by the first terminal jointly with the second terminal may also include wireless link measurement results between the multiple terminals, for example, the wireless link measurement results between the associated multiple UEs. PC5 measurement results, such as SideLink Reference Signal Received Power (SL-RSRP), Sidelink Discovery Reference Signal Received Power (SD-RSRP), Channel Occupancy Ratio (C channel Busy Ratio, CBR), etc.

FIG. 4 shows another schematic flowchart of a method for reporting a measurement report in an embodiment of the present application. The method 400 can be executed by the second terminal. In other words, the method may be performed by software or hardware installed on the second terminal. As shown in Figure 4, the method may include the following steps.

S410: The second terminal jointly reports a measurement report with the first terminal, where the first terminal and the second terminal are different terminals among a plurality of terminals associated with multipath data transmission.

This method is an execution method of the second terminal corresponding to method 300. Through this method, the second terminal can jointly report the measurement report with the first terminal, so that the network side device can obtain the measurement report jointly reported by the first terminal and the second terminal, Thus, mobility management can be performed based on measurement reports of multiple terminals associated with multipath data transmission.

In a possible implementation, the second terminal and the first terminal jointly report the measurement report may include: S4100, the second terminal sends the measurement result of the second terminal to the first terminal, wherein the measurement result The measurement report is reported by the first terminal through a measurement report.

For example, the second terminal may send the measurement result of the second terminal to the first terminal when it is determined that the second measurement reporting event is triggered. Alternatively, the second terminal may also send the measurement result of the second terminal to the first terminal after receiving the instruction from the first terminal.

In a possible implementation, the measurement results of the second terminal include:

(1) The measurement results of the serving cell of the second terminal;

(2) Measurement results of one or more neighboring cells of the second terminal.

Optionally, the UE sending the measurement report is UE1, and identifiers of other associated UEs may be indicated in the measurement report.

Optionally, the other associated UEs need to or preferentially provide measurement results of UE1's preferred neighbor cell (determined based on frequency priority and/or wireless signal quality) or cells of the same base station as UE1's preferred neighbor cell.

Among them, the process provided by the measurement report can include the following steps:

Step 1. UE1 obtains the configuration about the associated measurement report from the serving base station; the associated UE identifier and or associated measurement configuration includes an indication to enable aggregation measurement;

Step 2. UE1 determines that the measurement report event is triggered;

Step 3. UE1 obtains measurement results from other associated UEs;

Step 4. UE1 sends its own measurement results and the measurement results obtained by other associated UEs to the serving base station.

In another possible implementation, for multiple associated UEs, when the measurement reporting event of one UE (UE1) is triggered, indication information is sent to other associated UEs, and the indication information is used to instruct other associated UEs to send data to the base station. Associated measurement reports. The indication message may include: identification information of the measurement report (such as Measurement Object ID), indication of the neighboring cell to be measured, carrier frequency of the cell to be measured, etc.

The former means that the UE with the best wireless channel quality determines whether to trigger a measurement report by itself. The latter means that the UE with the best wireless channel quality reports the measurement results to the main UE, and the main UE decides whether to trigger a measurement report.

In yet another possible implementation, when multiple associated UEs use wireless connections, the base station may configure any associated UE to report wireless channel measurement values between multiple associated UEs to the base station. When PC5 connection technology is used between multiple associated UEs (i.e., Sidelink or sidelink for relay), the above-mentioned associated measurement report may also include PC5 measurement results between multiple associated UEs, such as S L-RSRP, SD-RSRP, CBR et al. When WiFi/BlueTooth technology is used between multiple associated UEs, the above-mentioned association measurement report may also include wireless channel measurement results between multiple associated UEs, For example, the strength of the beacon signal.
