[0047] Embodiments of the present application provide a wireless communication method, apparatus, terminal device, and storage medium.

[0048] Please refer to Figure 1 , which shows a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. The communication system may include: a terminal device 10 and a network device 20.

[0049] The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 may be distributed in a cell managed by each network device 20. The terminal device 10 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminal devices.

[0050] The network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in the 5G (5th-Generation, fifth-generation mobile communication technology) NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name "network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices.

[0051] Optionally, the network device 20 and the terminal device 10 communicate with each other via some air interface technology, such as a Uu interface.

[0052] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, advanced Long Term Evolution (LTE-A) system, NR system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to Unlicensed spectrum, LTE-U) system, NR-U (New Radio-Unlicensed, NR on unlicensed spectrum) system, wireless local area network (WLAN), wireless fidelity (WiFi), next generation communication system or other communication systems, etc.

[0053] The following describes it in detail with reference to specific embodiments.

[0054] For example, the terminal device is in the connected state. Figure 2 , Figure 2 1 is a flow chart of a wireless communication method provided in an embodiment of the present application, the wireless communication method comprising:

[0055] Step 110: The network device sends measurement configuration information to the terminal device, where the measurement configuration information includes a first reporting interval;

[0056] Step 120: If the terminal device meets the preset conditions, the terminal device sends a measurement report to the network device according to a second reporting interval, and the second reporting interval is smaller than the first reporting interval.

[0057] When the terminal device is in a connected state, the measurement of the signal quality of the cell by the terminal device is triggered by the network device. The network device sends measurement configuration information to the terminal device. Optionally, the measurement configuration information is carried in an RRC (Radio Resource Control) connection reconfiguration message, that is, the network device sends the measurement configuration information to the terminal device via an RRC connection reconfiguration message. Among them, the measurement configuration information includes a first reporting interval. Optionally, the measurement configuration information also includes a first reporting number, a measurement cycle, measurement parameters and / or a measurement cell, etc., which is not limited in the embodiments of the present application.

[0058] When the terminal device receives the measurement configuration information from the network device, it can parse the measurement configuration information to obtain the first reporting interval, etc. The reporting interval refers to the time interval between two measurement reports reported by the terminal device. The measurement report is used to indicate the signal quality of the cell measured by the terminal device. In an embodiment of the present application, if the terminal device meets the preset conditions, the terminal device can modify the reporting interval to speed up the reporting of the measurement report. Thus, after receiving the measurement configuration information from the network device, the terminal device can determine whether the terminal device currently meets the preset conditions; if the terminal device currently meets the preset conditions, the terminal device sends the measurement report to the network device according to the second reporting interval, and the second reporting interval is less than the first reporting interval.

[0059] The preset condition includes at least one of the following: the moving speed of the terminal device is greater than the preset speed; the terminal device is configured as a preset state. That is, after the terminal device receives the measurement configuration information from the network device, if the current moving speed of the terminal device is greater than the preset speed, the terminal device sends a measurement report to the network device according to the second reporting interval; or, if the terminal device is configured as a preset state, the terminal device sends a measurement report to the network device according to the second reporting interval; or, if the current moving speed of the terminal device is greater than the preset speed and the terminal device is configured as a preset state, the terminal device sends a measurement report to the network device according to the second reporting interval. Wherein, when the moving speed of the terminal device is greater than the preset speed, it can be considered that the terminal device is in a high-speed moving state. In addition, the user can independently configure the moving state of the terminal device, such as configuring the moving state of the terminal device to a preset state, and the preset state can be called a high-speed moving state.

[0060] It should be understood that when the terminal device is configured to a preset state, the terminal device does not necessarily have the mobility characteristics of the preset state, such as the movement speed of the terminal device does not necessarily have to be greater than the preset speed. In other words, the terminal device being configured to a preset state refers to the configuration characteristics of the terminal device, rather than the mobility characteristics that the terminal device is required to have.

[0061] For the method of determining whether the terminal device currently meets the preset conditions and the method of generating the measurement report, please refer to the following embodiments, which will not be described in detail here. It should be understood that if the terminal device currently does not meet the preset conditions, such as the current moving speed of the terminal device is less than the preset speed and / or the terminal device is not currently configured as a preset state, the terminal device sends a measurement report to the network device according to the first reporting interval. In the embodiment of the present application, when the terminal device currently does not meet the preset conditions, the measurement report is reported according to the first reporting interval configured by the network device to avoid unnecessary additional overhead for the terminal device.

[0062] When the terminal device currently meets the preset conditions, the terminal device sends a measurement report to the network device according to the second reporting interval. The second reporting interval can be any reporting interval randomly determined by the terminal device and smaller than the first reporting interval; or, the second reporting interval can be any reporting interval determined by the terminal device in combination with factors such as the device capability and / or current processing overhead of the terminal device and smaller than the first reporting interval. For other descriptions of the determination method of the second reporting interval, please refer to the following embodiments, which will not be elaborated here.

[0063] In one example, the measurement configuration information sent by the network device also includes a first reporting number. The reporting number refers to the total reporting number of the terminal device for the measurement report. The terminal device can send a measurement report to the network device according to the first reporting number, that is, the above-mentioned step 120, including: if the terminal device meets the preset conditions, the terminal device sends the measurement report to the network device according to the second reporting interval and the first reporting number. Alternatively, the terminal device may also determine the second reporting number, and send the measurement report to the network device according to the second reporting number, that is, the above-mentioned step 120, including: if the terminal device meets the preset conditions, the terminal device sends the measurement report to the network device according to the second reporting interval and the second reporting number.

[0064] Among them, the second reporting number is greater than the first reporting number. Optionally, the product of the second reporting interval and the second reporting number is equal to the product of the first reporting interval and the first reporting number. For example, the first reporting interval is T1, and the first reporting number is C1; the second reporting interval is T2, and the second reporting number is C2; then, T1×C1=T2×C2. That is, the terminal device can calculate the second reporting number when the first reporting interval, the first reporting number, and the second reporting interval are clearly defined. Of course, the second reporting number can also be any reporting number determined by the terminal device that is greater than the first reporting number.

[0065] In summary, the wireless communication method provided by the embodiment of the present application sends measurement configuration information to the terminal device through the network device, and the measurement configuration information includes a first reporting interval; if the terminal device is currently in a high-speed mobile state, the terminal device sends a measurement report to the network device according to the second reporting interval, and the second reporting interval is less than the first reporting interval. The embodiment of the present application takes into account that the terminal device will pass through multiple cell coverage areas in a short time in a high-speed mobile state, and the cell switching under the existing process has hysteresis, and the service cell after switching may be a poor cell or an unavailable cell. The embodiment of the present application shortens the reporting interval of the measurement report by the terminal device when the moving speed of the terminal device is greater than the preset speed to speed up the reporting of the measurement report, so that the terminal device can perform cell switching faster, thereby better ensuring the continuity of the service. In addition, the embodiment of the present application can also be configured by the user autonomously. The mobile state of the terminal device, when the terminal device is configured as a preset state, also triggers the accelerated reporting of the measurement report to meet the user's personalized needs for signal quality and service quality.

[0066] When the terminal device is in a connected state, after the terminal device sends a measurement report to the network device, the network device determines whether to perform a cell switch based on the measurement report. If a cell switch is performed, the network device sends cell switch information to the terminal device, and the terminal device performs the cell switch after receiving the cell switch information. That is, after the above step 120, the following steps are also included:

[0067] Step 130: If the measurement report meets the preset conditions, the network device sends cell switching information to the terminal device;

[0068] Step 140: The terminal device performs cell switching according to the cell switching information.

[0069] When the network device determines whether a cell handover can be performed based on the measurement report, it can determine whether the measurement report meets the preset conditions, and if the measurement report meets the preset conditions, the cell handover information is sent to the terminal device. Among them, the measurement report sent by the terminal device to the network device may include at least one cell and its measurement results, so that the preset conditions may include that the measurement result is greater than a preset threshold. Of course, the network device can also determine whether to perform a cell handover and the target cell to be switched to in combination with other contents, such as the priority of at least one cell and / or the number of device accesses to at least one cell.

[0070] The network device may perform step 130 each time it receives a measurement report; or the network device may perform step 130 according to a preset processing interval. For example, each time the network device receives a measurement report sent by the terminal device, it determines whether a cell handover can be performed for the measurement report. For another example, the network device determines whether a cell handover can be performed for the measurement reports received between the current processing moment and the previous processing moment according to a preset processing interval, such as determining whether a cell handover can be performed for the last measurement report received between the current processing moment and the previous processing moment.

[0071] When the terminal device receives the cell switching information from the network device, the terminal device performs the cell switching according to the cell switching information. Optionally, the cell switching information sent by the network device includes the target cell to which the terminal device needs to switch. When the terminal device receives the cell switching information, it switches from the current service cell to the target cell, and the target cell continues to provide network services for the terminal device. It should be understood that if the terminal device does not receive the cell switching information from the network device, the terminal device continues to measure the signal quality and upload the measurement report.

[0072] Next, a method for determining whether a terminal device currently meets a preset condition is described.

[0073] In one example, the terminal device can determine whether it is currently in a high-speed moving state based on the positioning function, that is, determine whether the current moving speed is greater than a preset speed based on the positioning function. For example, the terminal device obtains the current moving speed of the terminal device based on the positioning function; if the current moving speed of the terminal device is greater than the preset speed, the terminal device is currently in a high-speed moving state. Optionally, the terminal device's judgment on the high-speed moving state may be before step 110 or after step 110. The preset speed may be any preset speed threshold, which may be preset in the terminal device, user-defined, or configured by a network device, and this embodiment of the present application does not limit this.

[0074] In one example, the user can configure the mobile state of the terminal device independently, that is, the user configures the terminal device to a preset state. For example, the terminal device displays a user interface, which includes a mobile state adjustment control; the terminal device adjusts the current mobile state of the terminal device to a preset state in response to the user's opening operation on the mobile state adjustment control. Optionally, the user's setting operation for the preset state may be before step 110 or after step 110. When the user believes that the terminal device is no longer in the preset state or the terminal device does not need to speed up measurement reporting, the closing operation of the mobile state adjustment control may be triggered, so that the terminal device adjusts the current mobile state of the terminal device to a non-preset state in response to the user's closing operation on the mobile state adjustment control.

[0075] The preset state may also be referred to as a high-speed moving state, etc., and the non-preset state may also be referred to as a normal moving state or a low-speed moving state, etc. The preset state refers to a configuration feature of the terminal device, rather than a moving feature that the terminal device needs to have.

[0076] The following describes how to generate a measurement report.

[0077] In one example, the wireless communication method further includes the following steps:

[0078] Step 010: The terminal device measures the signal quality of a first cell to obtain a first measurement result; the first cell is a neighboring cell of a serving cell where the terminal device is located;

[0079] Step 020: If the first measurement result is greater than the quality threshold, the terminal device generates a measurement report according to the first measurement result.

[0080] Since the terminal device is currently in a connected state, the first cell may be configured by the network device. For example, the measurement configuration information sent by the network device also includes at least one measurement cell, which is a neighboring cell of the service cell where the terminal device is located, and the measurement cell includes the first cell. Of course, the first cell may also be determined by the terminal device itself.

[0081] The terminal device measures the signal quality of the first cell and obtains a first measurement result. The terminal device compares the first measurement result with the quality threshold. If the first measurement result is greater than the quality threshold, the terminal device generates a measurement report according to the first measurement result. Optionally, the quality threshold may be preset in the terminal device or configured by the network device. For example, the measurement configuration information sent by the network device also includes the quality threshold.

[0082] If the first measurement result corresponding to the first cell is less than the quality threshold, the signal quality of the first cell is poor, and the terminal device does not report the first measurement result corresponding to the first cell, but measures the signal quality of the second cell different from the first cell. That is, after the above step 010, it also includes:

[0083] Step 030: If the first measurement result is less than the quality threshold, the terminal device measures the signal quality of a second cell to obtain a second measurement result; the second cell is a neighboring cell of the serving cell where the terminal device is located, and the second cell is different from the first cell;

[0084] Step 040: If the second measurement result is greater than the quality threshold, the terminal device generates a measurement report according to the second measurement result.

[0085] The second cell may also be configured by the network device. For example, the measurement configuration information sent by the network device also includes at least one measurement cell, which is a neighboring cell of the service cell where the terminal device is located, and the measurement cell includes the second cell.

[0086] The terminal device measures the signal quality of the second cell to obtain a second measurement result. The terminal device compares the second measurement result with the quality threshold, and if the second measurement result is greater than the quality threshold, the terminal device generates a measurement report according to the second measurement result.

[0087] It should be understood that if the measurement result is equal to the quality threshold, the terminal device can generate a measurement report based on the measurement result, or continue to measure the signal quality of the next neighboring cell, and the embodiment of the present application does not limit this. For example, if the first measurement result is equal to the quality threshold, the terminal device can generate a measurement report based on the first measurement result, or measure the signal quality of the second cell to obtain a second measurement result.

[0088] Optionally, the signal quality measured by the terminal device includes RSRQ (Reference Signal Receiving Quality). Alternatively, the signal quality measured by the terminal device may also include: RSRP (Reference Signal Receiving Power), SINR (Signal to Interference plus Noise Ratio) and / or SNR (Signal Noise Ratio), etc.

[0089] The following describes a method for determining the second reporting interval.

[0090] In one example, the above step 120 includes: if the terminal device meets a preset condition and the first reporting interval is greater than the minimum reporting interval supported by the terminal device, the terminal device sends a measurement report to the network device according to the second reporting interval.

[0091] In this example, when the terminal device currently meets the preset conditions, the terminal device can compare the first reporting interval configured by the network device with the minimum reporting interval supported by the terminal device. If the terminal device currently meets the preset conditions and the first reporting interval is greater than the minimum reporting interval supported by the terminal device, the terminal device determines the second reporting interval and sends a measurement report to the network device according to the second reporting interval.

[0092] Optionally, the second reporting interval is equal to the minimum reporting interval supported by the terminal device; or, the second reporting interval is greater than the minimum reporting interval supported by the terminal device. That is, the second reporting interval is less than the first reporting interval, and greater than or equal to the minimum reporting interval supported by the terminal device. For example, if the current processing overhead of the terminal device is small, the second reporting interval determined by the terminal device is the minimum reporting interval supported by it, or the terminal device directly sends the measurement report to the network device according to the minimum reporting interval supported by it; if the current processing overhead of the terminal device is large, the second reporting interval determined by the terminal device is greater than the minimum reporting interval supported by it.

[0093] Exemplarily, the first reporting interval configured by the network device is 1 minute, and the minimum reporting interval supported by the terminal device is 10240 milliseconds (i.e., 10.24 seconds). The first reporting interval is greater than the minimum reporting interval supported by the terminal device. At this time, if the terminal device is currently in a high-speed mobile state, the terminal device can send a measurement report to the network device according to the second reporting interval, and the second reporting interval is less than 1 minute and greater than or equal to 10.24 seconds. For example, the second reporting interval is 30 seconds or 45 seconds.

[0094] It should be understood that if the terminal device meets the preset conditions and the first reporting interval is equal to the minimum reporting interval supported by the terminal device, the terminal device sends a measurement report to the network device according to the first reporting interval; if the terminal device meets the preset conditions and the first reporting interval is less than the minimum reporting interval supported by the terminal device, the terminal device sends a measurement report to the network device according to the minimum reporting interval supported by it.

[0095] Exemplarily, the first reporting interval configured by the network device is 1 minute, and the minimum reporting interval supported by the terminal device is also 1 minute. At this time, if the terminal device meets the preset conditions, the terminal device can send a measurement report to the network device according to the reporting interval of 1 minute.

[0096] Exemplarily, the first reporting interval configured by the network device is 640 milliseconds (i.e. 0.64 seconds), and the minimum reporting interval supported by the terminal device is 1024 milliseconds (i.e. 1.024 seconds). At this time, if the terminal device meets the preset conditions, the terminal device can send a measurement report to the network device according to the reporting interval of 1.024 seconds.

[0097] Below, the wireless communication method provided in the embodiment of the present application is introduced and explained with a specific example.

[0098] For example, the terminal device is in a connected state and currently meets the preset conditions. Figure 3 , Figure 3 1 is a flow chart of a wireless communication method provided in an embodiment of the present application, the wireless communication method comprising:

[0099] Step 310: The network device sends measurement configuration information to the terminal device, where the measurement configuration information includes a first reporting interval and a first reporting number;

[0100] Step 320: The terminal device measures the signal quality of the neighboring cell of the current serving cell and obtains a measurement result;

[0101] Step 330: The terminal device determines whether the measurement result is greater than the quality threshold; if the measurement result is greater than the quality threshold, the process starts from the following step 340; if the measurement result is less than the quality threshold, the process starts from step 320 again;

[0102] Step 340: The terminal device generates a measurement report according to the measurement result;

[0103] Step 350: The terminal device sends a measurement report to the network device according to the second reporting interval and the second reporting number;

[0104] Step 360: The network device determines whether to perform a cell handover according to the measurement report; if the network device determines to perform a cell handover, the process starts from the following step 370; if the network device determines not to perform a cell handover, the process starts again from step 320;

[0105] Step 370: The network device sends cell switching information to the terminal device;

[0106] Step 380: The terminal device performs cell switching according to the cell switching information.

[0107] For example, the terminal device is in idle state. Figure 4 , Figure 4 1 is a flow chart of a wireless communication method provided in an embodiment of the present application, the wireless communication method comprising:

[0108] Step 410: The terminal device measures the signal quality of the neighboring cell of the current serving cell and obtains a measurement result;

[0109] Step 420: The terminal device determines whether the measurement result is greater than the quality threshold; if the measurement result is greater than the quality threshold, the process starts from the following step 430; if the measurement result is less than the quality threshold, the process starts again from step 410;

[0110] Step 430: The terminal device determines whether the neighboring cell meets the S criterion and the R criterion; if the neighboring cell meets the S criterion and the R criterion, the following step 440 is executed; if the neighboring cell does not meet the S criterion or the R criterion, the step 410 is executed again;

[0111] Step 440: The terminal device switches from the serving cell to the neighboring cell.

[0112] In an embodiment of the present application, when the terminal device is in an idle state, the reselection priority of each cell is ignored and the priority of the neighboring cell of the serving cell where the terminal device is currently located is assumed to be higher than the priority of the serving cell, so that the terminal device will continue to measure the signal quality of the neighboring cells of the serving cell.

[0113] After measuring the signal quality of the neighboring cell, the terminal device can obtain the measurement result. By comparing the measurement result with the quality threshold, the terminal device can determine the signal quality of the neighboring cell. For an introduction to the signal quality and quality threshold, please refer to the above embodiment, which will not be described in detail here. If the measurement result of the neighboring cell is greater than the quality threshold, the terminal device further determines whether the neighboring cell meets the S criterion and the R criterion. If the measurement result of the neighboring cell is less than the quality threshold, the signal quality of the neighboring cell is poor, and the terminal device continues to measure the signal quality of the next neighboring cell.

[0114] Exemplarily, the S criterion is based on the level strength Srxlev and the signal quality Squal, the level strength Srxlev usually refers to the signal level strength transmitted by the SSB (Synchronized Signal Block) beam, and Squal is usually based on RSRQ. For example, the calculation formula of the S criterion includes:

[0115] Srxlev=Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–Qoffsettemp

[0116] Squal=Qqualmeas–(Qqualmin+Qqualminoffset)-Qoffsettemp

[0117] Among them, Qrxlevmeas is the measured RSRP value, Qqualmeas is the measured RSRQ value, Qrxlevmin is the minimum reception level, Qqualmin is the minimum reception quality, Qrxlevminoffset and Qqualminoffset are the corresponding offset values, Pcompensation is the power compensation, and Qoffsettemp is a temporary offset value.

[0118] Exemplarily, the R criterion is used to determine whether a terminal device reselects from one cell to another when the frequency priorities are the same. The R criterion takes into account the signal strength of the serving cell and the neighboring cell, and introduces an offset Qoffset to adjust the difficulty of reselection. For example, the calculation formula of the R criterion includes:

[0119] Rs=Qmeas,s+Qhyst-Qoffsettemp

[0120] Rn=Qmeas,n-Qoffset-Qoffsettemp

[0121] Among them, Qmeas is the measured RSRP value, Qhyst is the cell reselection hysteresis, and Qoffset is the offset between the serving cell and the neighboring cell, which is used to control the difficulty of cell reselection.
