[0002] This application claims priority to Chinese Patent Application No. 202411569274.2, filed on November 5, 2024, entitled "Wireless Communication Method, Terminal and Network Side Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a wireless communication method, terminal, and network-side equipment. Background Technology

[0004] The 3rd Generation Partnership Project (3GPP) proposed the Minimization of Drive Tests (MDT) technique. MDT technology directly uses user equipment (UE) within the network to measure and report network coverage. MDT technology offers advantages such as low overhead and short optimization cycles, thereby significantly reducing the cost of network optimization and maintenance for mobile operators and improving the efficiency of network optimization.

[0005] From the perspective of MDT measurement methods, MDT technology can be divided into Immediate MDT and Logged MDT. Immediate MDT is characterized by the UE performing measurements while in Radio Resource Control (RRC) connected mode; if the configured reporting conditions are met, the UE will report an MDT report to the base station. Logged MDT is characterized by the base station configuring the UE with recording settings while the UE is in RRC connected mode. The UE can only perform measurements and record the results in RRC idle / inactive mode; it can only report to the base station after returning to RRC connected mode.

[0006] In related technologies, operators need to update SSB configuration or beam configuration to save network energy.

[0007] However, since the information recorded in the recorded MDT is usually cell-level measurement results of neighboring cells, such as the cell's Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ), and cell-level measurement results cannot be used by network-side equipment to update SSB configuration or beam configuration, network-side equipment cannot update SSB configuration or beam configuration based on the information recorded in the recorded MDT.

[0048] To facilitate a better understanding of the embodiments of this application, the related technologies are described.

[0049] (1) Minimization of Drive Tests (MDT) technique.

[0050] To ensure network quality, operators need to use drive tests (DPTs) to assess network performance. Traditional DPTs involve operators deploying dedicated personnel and equipment to test signal quality at various locations within the network to check for coverage issues. However, this method is resource-intensive and ineffective because DPT personnel typically cannot easily access all locations. To address this problem, the 3rd Generation Partnership Project (3GPP) proposed Multi-User Test (MDT) technology. MDT directly uses user equipment (UE) within the network to measure and report network coverage. This approach offers the advantage of directly utilizing users to test network coverage, avoiding significant manpower and resource expenditures for operators, and covering any location within the network that users can actually reach, making it more effective than traditional DPTs in terms of coverage scope.

[0051] MDT (Multi-Targeting Technology) offers advantages such as low overhead and short optimization cycles, significantly reducing the cost of network optimization and maintenance for mobile operators and improving the efficiency of network optimization. Simultaneously, MDT can collect network information in areas inaccessible by traditional drive testing (such as indoors and narrow roads). Therefore, MDT can provide stronger support for evaluating network performance and improving network quality, ultimately leading to higher user satisfaction.

[0052] From the perspective of MDT measurement methods, MDT technology can be divided into Immediate MDT and Logged MDT.

[0053] The characteristic of immediate MDT is that the UE performs measurements in the Radio Resource Control (RRC) connected state, and the measurement method is Radio Resource Management (RRM) in the multiplexing protocol. If the configured reporting conditions are met, the UE will report an MDT report to the base station. When the UE switches to another cell or enters the RRC idle state, its configured MDT configuration will be deleted.

[0054] The characteristic of recorded MDT is that the base station configures the recorded MDT for the UE when the UE is in RRC connected state. The UE can only perform measurements and record the results in RRC idle / inactive state. The UE can only report to the base station after returning to RRC connected state. The recorded MDT configuration persists after being configured until the configured duration is reached.

[0055] Record-based MDT can be implemented using the following elements:

[0056] Record-based MDT configuration can be configured for both periodic recording and event-triggered recording. Events include the following two types:

[0057] Out of coverage: This means periodically monitoring whether a device is outside of network coverage. If so, a recorded MDT is performed.

[0058] Poor signal quality in the serving / resident cell (Serving becomes worse than threshold) is similar to an A2 event, meaning the signal quality in the serving / resident cell is below the threshold. In such cases, a recorded multidisciplinary team (MDT) is performed.

[0059] If the terminal performs a recording-based MDT, the following information will be recorded for neighboring cells:

[0060] Physical Cell Identity (PCI) is used to identify neighboring cells;

[0061] Cell-level measurement results

[0062] The number of beam-level measurements that exceed a specific threshold (absThreshSS-BlocksConsolidation).

[0063] (2) Network energy saving.

[0064] Network energy efficiency is listed as one of the 13 performance requirements of IMT-2020. Most of the power consumption in NR networks comes from base stations, with 90% of the power consumption of an NR base station coming from the Active Antenna Unit (AAU). Due to higher frequency bands, wider bandwidth, and more Transmitter Receivers (TRXs), the power consumption of a single NR base station is 3 to 4 times higher than that of LTE. Furthermore, in terms of operating expenses (OPEX), base station electricity costs account for nearly 20% of the total network operating costs. For some operators, electricity costs are more than half of their total profits. Therefore, NR network energy saving is becoming increasingly critical for the great success of 5G. Depending on the actual load, base stations can implement different levels of energy-saving measures, such as shutting down the base station, shutting down carriers / cells, shutting down channels, shutting down Synchronization Signal / PBCH Block (SS / PBCH Block, SSB) / beams, shutting down antennas / panels, discontinuous transmission (DTX) and / or discontinuous reception (DRX), adaptive Channel State Information (CSI), etc.

[0065] As can be seen from the above, operators will shut down the SSB beams of some cells in overlapping coverage areas due to network energy-saving needs. However, recorded MDT only records the cell-level measurement results of neighboring cells, which is not suitable for advanced functions that require more detailed data, thus reducing the scalability and flexibility of recorded MDT. For example, since recorded MDT does not record the SSB beam identifiers and beam-level measurement results of neighboring cells, it cannot provide complete overlapping coverage information. Therefore, the network cannot determine which SSB beams in the overlapping coverage area can be shut down through recorded MDT. This application introduces first configuration information to indicate the beam-level recording configuration, so that when the terminal performs recorded MDT based on the first configuration information, it can record beam-level information. The beam-level information can reflect the complete beam overlapping coverage information. That is, the MDT report generated and reported by the terminal can be used to assist network-side equipment in updating SSB configuration or beam configuration, which is equivalent to being able to update the SSB configuration or beam configuration based on the information recorded by recorded MDT.

[0066] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0067] Figure 2 is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application.

[0068] As shown in Figure 2, the wireless communication method 200 may include at least some of the following:

[0069] S201, the terminal receives first configuration information from the network-side device, the first configuration information being used to indicate the recording configuration of the beam level.

[0070] For example, the first configuration information may be a Logged Measurement Configuration, which is used to record beam-level measurement results for optimizing network performance. For instance, the beam-level measurement results may be used to characterize at least one of the following: the beam-level coverage of the stationary cell, and the beam-level coverage of neighboring cells.

[0071] For example, the beam-level recording configuration may include the SSB recording configuration.

[0072] For example, the first configuration information can be used to indicate the beam-level recording configuration of neighboring cells and / or the beam-level recording configuration of the serving cell. The serving cell can also be referred to as the serving cell.

[0073] S202, the terminal performs a record-based minimized road test (MDT) based on the first configuration information.

[0074] For example, when the terminal is in the RRC_IDLE or RRC_INACTIVE state, the terminal performs a recorded MDT based on the first configuration information.

[0075] S203, the terminal generates and sends the recorded MDT report to the network-side device.

[0076] For example, after the terminal enters the RRC connection state, it generates and sends the MDT report to the network-side device.

[0077] In this embodiment of the application, the first configuration information is used to indicate the recording configuration at the beam level, so that when the terminal performs a recording-based MDT based on the first configuration information, it can record beam-level information. The beam-level information can reflect the complete beam overlap coverage information. That is, the MDT report generated and reported by the terminal can be used to assist the network-side device in updating the SSB configuration or beam configuration, which is equivalent to being able to update the SSB configuration or beam configuration based on the information recorded by the recording-based MDT.

[0078] In some embodiments, the first configuration information includes at least one of the following:

[0079] The first indication information is used to indicate the maximum number of SSB indexes for records;

[0080] The second instruction information is used to indicate whether to record the index of the first SSB;

[0081] The third indication information is used to indicate whether to record the measurement results of the first SSB.

[0082] For example, the first indication information may indicate the maximum number of recorded SSB indexes in a single cell or multiple cells.

[0083] For example, the first SSB includes at least one of the following: the terminal's optimal SSB, or an SSB that meets the reporting conditions. The optimal SSB is the SSB with the best measurement results, such as the SSB with the highest RSRP, RSRQ, or SINR values. The SSB that meets the reporting conditions includes at least one of the following: a protocol-defined SSB, or an SSB that meets a trigger event, the trigger event being used to trigger the recorded MDT. The index of the first SSB can also be referred to as the index of the first beam, the beam-level index of the first SSB, or other terms with similar meanings, and the measurement results of the first SSB can also be referred to as the measurement results of the first beam, the measurement results of the first SSB, or other terms with similar meanings; this application does not specifically limit this.

[0084] For example, the measurement results of the first SSB include at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR).

[0085] For example, the first configuration information can be implemented through the following elements:

[0086] In this embodiment, the terminal can directly perform the recording-based MDT based on at least one of the first indication information, the second indication information, and the third indication information, which allows the network-side device to flexibly control the amount of data recorded by the terminal, thereby reducing the impact on the terminal's storage.

[0087] In some embodiments, the first configuration information includes configuration information for a triggering event, which is used to trigger the recorded MDT.

[0088] In this embodiment, the first configuration information includes configuration information for triggering events. The triggering events are used to trigger the recording MDT, which can reduce the terminal from performing unnecessary recording MDT, thereby reducing the impact on the terminal's storage.

[0089] In some embodiments, the configuration information for the triggering event includes configuration information for a first event, wherein the configuration information for the first event includes at least one of the following:

[0090] The trigger threshold for the first event;

[0091] The hysteresis parameter of the first event;

[0092] The duration threshold of the first event.

[0093] For example, the trigger threshold for the first event can be a negative value, 0, or a positive number.

[0094] For example, the first event refers to: the beam-level measurement of the neighboring cell becomes offset better than that of the stationary cell. For instance, the first event refers to: the optimal SSB measurement of the neighboring cell is better than the SSB measurement of the stationary cell.

[0095] Wherein, S202 includes at least one of the following:

[0096] If the first difference is greater than or equal to the sum of the trigger threshold of the first event and the hysteresis parameter of the first event, the terminal performs the recorded MDT.

[0097] If the first difference is greater than or equal to the sum of the trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event, the terminal performs the recorded MDT.

[0098] If the first difference is greater than or equal to the trigger threshold of the first event, the terminal performs the recorded MDT;

[0099] If the first difference is greater than or equal to the trigger threshold of the first event and the duration of the first event is greater than or equal to the duration threshold of the first event, the terminal performs the recorded MDT.

[0100] The first difference is the difference between the beam level measurement result of the neighboring cell and the beam level measurement result of the stationed cell.

[0101] For example, the first difference is the difference between the measurement result of the optimal SSB of the neighboring cell and the measurement result of the SSB of the stationed cell.

[0102] For example, if the configuration information of the first event includes a hysteresis parameter of the first event, then: if the first difference is greater than or equal to the sum of the trigger threshold of the first event and the hysteresis parameter of the first event, the terminal performs the recorded MDT; or, if the first difference is greater than or equal to the sum of the trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event, the terminal performs the recorded MDT. If the configuration information of the first event does not include a hysteresis parameter of the first event, then: if the first difference is greater than or equal to the trigger threshold of the first event, the terminal performs the recorded MDT; or, if the first difference is greater than or equal to the trigger threshold of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event, the terminal performs the recorded MDT.

[0103] For example, if the configuration information of the first event includes a duration threshold for the first event, then: if the first difference is greater than or equal to the sum of the trigger threshold of the first event and the hysteresis parameter of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event, the terminal performs the recorded MDT; or, if the first difference is greater than or equal to the trigger threshold of the first event, and the duration of the first event is greater than or equal to the duration threshold of the first event, the terminal performs the recorded MDT. If the configuration information of the first event does not include a duration threshold for the first event, then: if the first difference is greater than or equal to the sum of the trigger threshold of the first event and the hysteresis parameter of the first event, the terminal performs the recorded MDT; or, if the first difference is greater than or equal to the trigger threshold of the first event, the terminal performs the recorded MDT.

[0104] In some embodiments, the configuration information for the triggering event includes configuration information for a second event, wherein the configuration information for the second event includes at least one of the following:

[0105] The trigger threshold for the second event;

[0106] The beam count threshold for the second event;

[0107] The hysteresis parameter of the second event;

[0108] The duration threshold of the second event.

[0109] For example, the trigger threshold for the second event is a positive number.

[0110] For example, the second event refers to the situation where beam-level measurements of multiple cells become better than a threshold. The multiple cells include neighboring cells and hosted cells.

[0111] Wherein, S202 includes at least one of the following:

[0112] If the first number is greater than or equal to the beam number threshold of the second event, the terminal performs the recorded MDT;

[0113] If the number of beams in the first event is greater than or equal to the number of beams in the second event, and the duration of the second event is greater than or equal to the duration of the second event, the terminal performs the recorded MDT.

[0114] Wherein, the first quantity is the number of beams whose beam-level measurement results are greater than or equal to the trigger threshold of the second event, or the number of beams whose beam-level measurement results are greater than or equal to the sum of the trigger threshold of the second event and the hysteresis parameter of the second event.

[0115] For example, the first quantity is the number of SSBs in neighboring cells whose measurement results are greater than or equal to the trigger threshold of the second event. Alternatively, the first quantity is the number of SSBs in both neighboring and camped cells whose measurement results are greater than or equal to the trigger threshold of the second event. Alternatively, the first quantity is the number of SSBs in neighboring cells whose measurement results are greater than or equal to the sum of the trigger threshold of the second event and the hysteresis parameter of the second event. Alternatively, the first quantity is the number of SSBs in both neighboring and camped cells whose measurement results are greater than or equal to the sum of the trigger threshold of the second event and the hysteresis parameter of the second event.

[0116] For example, if the configuration information of the second event does not include the hysteresis parameter of the second event, then the first quantity is the number of beams whose beam-level measurement results are greater than or equal to the trigger threshold of the second event. If the configuration information of the second event includes the hysteresis parameter of the second event, then the first quantity is the number of beams whose beam-level measurement results are greater than or equal to the sum of the trigger threshold of the second event and the hysteresis parameter of the second event.

[0117] For example, if the configuration information of the second event does not include a duration threshold for the second event, then: if the first number is greater than or equal to the beam number threshold of the second event, the terminal performs the recorded MDT. If the configuration information of the second event includes a duration threshold for the second event, then: if the first number is greater than or equal to the beam number threshold of the second event, and the duration of the second event is greater than or equal to the duration threshold of the second event, the terminal performs the recorded MDT.

[0118] In some embodiments, the MDT report includes at least one of the following:

[0119] Index of the first SSB;

[0120] The first SSB measurement results.

[0121] For example, the first SSB includes at least one of the following: the terminal's optimal SSB, or an SSB that meets the reporting conditions. The optimal SSB is the SSB with the best measurement results, such as the SSB with the highest RSRP, RSRQ, or SINR values. The SSB that meets the reporting conditions includes at least one of the following: a protocol-defined SSB, or an SSB that meets a trigger event, the trigger event being used to trigger the recorded MDT. The index of the first SSB can also be referred to as the index of the first beam, the beam-level index of the first SSB, or other terms with similar meanings, and the measurement results of the first SSB can also be referred to as the measurement results of the first beam, the measurement results of the first SSB, or other terms with similar meanings; this application does not specifically limit this.

[0122] For example, the measurement results of the first SSB include at least one of the following: RSRP, RSRQ, SINR.

[0123] For example, the configuration of the triggering event can be implemented as the following elements:

[0124] In this embodiment, the MDT report includes at least one of the following: the index of the first SSB, the measurement result of the first SSB, which is equivalent to providing the network with beam overlap coverage information. That is, the MDT report generated and reported by the terminal can be used to assist the network-side device in updating the SSB configuration or beam configuration, which is equivalent to being able to update the SSB configuration or beam configuration based on the information recorded by the recorded MDT.

[0125] In some embodiments, prior to S203, the method 200 further includes at least one of the following:

[0126] The terminal sends a fourth indication message to the network-side device, the fourth indication message being used to indicate that the measurement results of the recorded MDT are available;

[0127] The terminal receives a first request from the network-side device, the first request being used to request the MDT report of the recorded MDT.

[0128] For example, after the terminal sends the fourth indication information to the network-side device, it receives the first request from the network-side device, and then the terminal responds to the first request by sending the MDT report to the network-side device.

In this case, as shown in Figure 3(b), the network-side device can shut down SSB2 & SSB4 of cell 1 based on energy-saving requirements.

[0174] Of course, if the configuration information of the first event does not include the hysteresis parameter of the first event, then if the measurement result of the beam level of the neighboring cell minus the measurement result of the beam level of the stationary cell is greater than or greater than the trigger threshold of the first event, the entry condition of the first event is met; if the duration of the first event reaches the duration threshold of the first event, then a recorded MDT is triggered. Alternatively, if the configuration information of the first event does not include the duration threshold of the first event, then if the measurement result of the beam level of the neighboring cell minus the measurement result of the beam level of the stationary cell is greater than or greater than the trigger threshold of the first event plus the hysteresis parameter of the first event, then the entry condition of the first event is met, and a recorded MDT is directly triggered.

[0175] If the triggering event includes the second event, the terminal triggers the recorded MDT in the following manner:

[0176] If the number of beams in the measurement results of the beam level of the neighboring cell and / or the measurement results of the beam level of the stationary cell is greater than or greater than the number of beams in the second event (the trigger threshold of the second event plus the hysteresis parameter of the second event), then the entry condition of the second event is met; if the duration of the second event reaches the duration threshold of the second event, then the recorded MDT is triggered.

[0177] Of course, if the configuration information of the second event does not include the hysteresis parameter of the second event, and the number of beams in the measurement results of the beam level of the neighboring cell and / or the measurement results of the beam level of the camping cell (> or ≥ the trigger threshold of the second event) is greater than or ≥ the beam number threshold of the second event beam, then the entry condition of the second event is met; if the duration of the second event reaches the duration threshold of the second event, then a recorded MDT is triggered. Alternatively, if the configuration information of the first event does not include the duration threshold of the second event, and the number of beams in the measurement results of the beam level of the neighboring cell and / or the measurement results of the beam level of the camping cell (> or ≥ the trigger threshold of the second event + the hysteresis parameter of the second event) is greater than or ≥ the beam number threshold of the second event beam, then the entry condition of the second event is met, and a recorded MDT is directly triggered.

[0178] S303, the terminal sends a fourth instruction message to the network-side device.

[0179] The fourth indication information is used to indicate that the measurement results of the recorded MDT are available.

[0180] S304, the terminal receives a first request from the network-side device.

[0181] The first request is used to request the MDT report of the recorded MDT.

[0186] The first SSB includes at least one of the following: the terminal's optimal SSB, or an SSB that meets the reporting conditions. The optimal SSB is the SSB with the best measurement results, such as the SSB with the highest RSRP, RSRQ, or SINR values. The SSB that meets the reporting conditions includes at least one of the following: a protocol-defined SSB, or an SSB that meets a trigger event, the trigger event being used to trigger the recorded MDT. The measurement results of the first SSB include at least one of the following: RSRP, RSRQ, or SINR.

[0187] In this embodiment, the first configuration information is used to indicate the beam-level recording configuration, enabling the terminal to record beam-level information when performing a recording-based MDT based on the first configuration information. This beam-level information reflects complete beam overlap and coverage information; that is, the MDT report generated and reported by the terminal can be used to assist network-side devices in updating SSB or beam configurations. This is equivalent to being able to update the SSB or beam configuration based on the information recorded in the recording-based MDT. Furthermore, the first configuration information includes configuration information for triggering events. These triggering events are used to trigger the recording-based MDT, reducing unnecessary recording-based MDT execution by the terminal and thus minimizing the impact on the terminal's storage.
