Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a method, apparatus, device and storage medium for configuring a detection period of a terminal device. Background Art

[0002] The 5G network has a hybrid networking mode of NR TDD (New Radio Time Division Duplexing) and NR FDD (New Radio Frequency Division Duplexing). The UE (User Equipment) sends an SRS (Sounding Reference Signal) within the activated BWP (Bandwidth Part) bandwidth for uplink channel estimation. Existing 5G base stations can be configured with SRS sounding signals of different periods. Once the configuration is completed, all terminal devices under the 5G base station use the same SRS period. In the NR TDD and NR FDD hybrid networking mode, since all terminal devices use the same SRS period, the 5G TDD mode and FDD mode are not distinguished, and the different throughput requirements of different terminal devices are not taken into account, resulting in poor downlink throughput of the terminal devices. Summary of the Invention

[0003] The purpose of the embodiments of the present invention is to provide a method, apparatus, device and storage medium for configuring the detection period of a terminal device, which takes into account the throughput requirements of different terminal devices in the NR TDD and NR FDD hybrid networking mode, configures the SRS detection period on demand, and can effectively improve the downlink throughput of the terminal device.

[0004] To achieve the above objectives, an embodiment of the present invention provides a method for configuring a detection period of a terminal device, comprising:

[0005] When detecting that a target terminal resides within the coverage of a first base station, issuing a measurement control instruction to the target terminal; wherein the first base station operates in a frequency division duplex mode;

[0006] receiving a neighboring cell measurement result sent by the target terminal, and when a second base station whose signal level exceeds a preset signal threshold is present in the neighboring cell measurement result, sending instruction information for switching connection to the second base station to the target terminal; wherein the second base station operates in time division duplex mode;

[0007] After the target terminal is connected to the second base station, obtaining a sounding reference signal of the target terminal;

[0008] When it is determined based on the detection reference signal that the target terminal meets the preset non-weak coverage condition, the standard detection period currently configured by the second base station for the terminal device is obtained, and the second base station is instructed to configure the detection period of the target terminal as the target detection period; wherein, the target detection period is less than the standard detection period.

[0009] As an improvement to the above solution, before issuing the measurement control instruction to the target terminal, the method further includes:

[0010] Collecting the cumulative number of bytes of radio link control of the terminal equipment residing in the first base station within a preset time period;

[0011] When the accumulated number of bytes is greater than a preset byte number threshold, it is determined that the terminal device is a target terminal that meets the throughput requirement condition.

[0012] As an improvement to the above solution, the method further includes:

[0013] After configuring a target detection period of the target terminal once, respectively obtaining the four-stream transmission ratios of the second base station before and after configuring the target detection period;

[0014] When the four-stream transmission ratio of the second base station after configuring the target detection period is greater than the four-stream transmission ratio of the second base station before configuring the target detection period, keeping the current target detection period of the target terminal unchanged;

[0015] When the four-stream transmission ratio of the second base station after configuring the target detection period is less than or equal to the four-stream transmission ratio of the second base station before configuring the target detection period, the detection period of the target terminal is configured as the detection period before performing the configuration operation.

[0016] As an improvement to the above solution, the method further includes:

[0017] After configuring the target detection period of the target terminal, if the target terminal still meets the throughput requirement, the target detection period of the target terminal is reduced until the target terminal does not meet the throughput requirement or the target detection period is equal to a preset minimum detection period.

[0018] As an improvement to the above solution, after acquiring the sounding reference signal of the target terminal, the method further includes:

[0019] Obtaining a reference signal received power and a signal-to-noise ratio in the sounding reference signal;

[0020] When the reference signal received power is greater than a preset received power threshold and the signal-to-interference ratio is greater than a preset ratio threshold, determining that the target terminal meets the non-weak coverage condition;

[0021] When the reference signal received power is less than or equal to the received power threshold, or the signal-to-interference ratio is greater than or equal to the ratio threshold, it is determined that the target terminal does not meet the non-weak coverage condition.

[0022] As an improvement to the above solution, the method further includes:

[0023] When it is determined according to the sounding reference signal that the target terminal does not meet the non-weak coverage condition, the second base station is instructed to configure the sounding period of the target terminal to be the standard sounding period.

[0024] As an improvement to the above solution, the four-stream transmission ratio is the ratio of the number of downlink transmission bytes to the total number of transmission bytes when the number of spatial division multiplexing streams of the second base station is four.

[0025] To achieve the above-mentioned purpose, an embodiment of the present invention further provides a detection period configuration device for a terminal device, comprising:

[0026] a measurement instruction sending module, configured to, upon detecting that a target terminal resides within the coverage area of ​​a first base station, send a measurement control instruction to the target terminal, so that the target terminal measures a neighboring base station; wherein the target terminal is a terminal that meets a preset throughput requirement condition, and the first base station operates in a frequency division duplex mode;

[0027] an indication information sending module, configured to receive a neighboring cell measurement result sent by the target terminal, and when a second base station whose signal level exceeds a preset signal threshold is present in the neighboring cell measurement result, send indication information of switching connection to the second base station to the target terminal; wherein the second base station operates in time division duplex mode;

[0028] a sounding reference signal acquisition module, configured to acquire a sounding reference signal of the target terminal after the target terminal is connected to the second base station;

[0029] A detection period configuration module is used to obtain the standard detection period currently configured by the second base station to the terminal device when it is determined that the target terminal meets the preset non-weak coverage condition based on the detection reference signal, and instruct the second base station to configure the detection period of the target terminal as the target detection period; wherein, the target detection period is less than the standard detection period.

[0030] To achieve the above-mentioned purpose, an embodiment of the present invention also provides a detection period configuration device for a terminal device, comprising a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein when the processor executes the computer program, it implements the detection period configuration method for the terminal device as described in any of the above embodiments.

[0031] To achieve the above-mentioned purpose, an embodiment of the present invention also provides a computer-readable storage medium, which includes a stored computer program, wherein when the computer program is running, the device where the computer-readable storage medium is located is controlled to execute the detection period configuration method of the terminal device as described in any of the above embodiments.

[0032] Compared with the prior art, the method, apparatus, device and storage medium for configuring the detection period of the terminal device disclosed in the present invention, when detecting that a target terminal that meets the throughput requirement conditions resides within the coverage of the NR FDD base station, sends an indication message of switching to the NR TDD base station to the target terminal, and after the target terminal is connected to the NR TDD base station, obtains the detection reference signal of the target terminal, and when the detection reference signal meets the non-weak coverage condition, obtains the standard detection period currently configured by the NR TDD base station and configures the target detection period of the target terminal to be less than the standard detection period. By setting a smaller detection period for the target terminal, the base station beamforming effect is better, the downlink transmission rate of the target terminal is improved, and the downlink throughput of the target terminal is thereby improved. Since the throughput requirements of different terminal devices are taken into account in the NR TDD and NR FDD hybrid networking mode, the SRS detection period is configured on demand, which can effectively improve the downlink throughput of the terminal device.

[0033] In addition, the positions of different users under the 5G base station change at different speeds. For users with high wireless throughput requirements and fast position changes, a smaller SRS detection period is set for their target terminal, so that the target terminal can report the detection signal and strength more quickly, thereby enabling the 5G base station to track changes in channel conditions more quickly and perform beamforming more accurately, thereby improving the downlink throughput of the target terminal; the existing 5G network is a multi-user environment. If multiple users under the 5G base station meet such characteristics, it is necessary to configure an SRS period that is smaller than the default SRS period for such users, so that the downlink channel weight estimation is more accurate, the downlink transmission rate of such users is improved, and the overall throughput of the 5G base station is improved.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] In existing 5G networks, 5G terminals periodically transmit SRS signals, or uplink sounding reference signals, after entering the connected state. SRS is an uplink pilot signal sent by user equipment to radio access network equipment to determine the channel quality of each wireless channel within each frequency band. SRS can define a period parameter, which represents the configured user SRS period. The user's actual SRS period is determined by this parameter value, the system's available SRS resources, slot allocation, and UE capabilities. The average user's actual SRS period is no less than this parameter value. The SRS period parameter range includes: SL5 (5 slots), SL10 (10 slots), SL20 (20 slots), SL40 (40 slots), SL80 (80 slots), SL160 (160 slots), SL320 (320 slots), and SL640 (640 slots). The actual SRS period values ​​(in milliseconds) are: SL5: 2.5 ms; SL10: 5 ms; SL20: 10 ms; SL40: 20 ms; SL80: 40 ms; SL160: 80 ms; SL320: 160 ms; and SL640: 320 ms. A larger period parameter value increases the SRS period and supports a greater number of users. A smaller period parameter value shortens the SRS period and supports a smaller number of users.

[0039] The SRS detection signal has two main purposes. One is the measurement of the user uplink level and quality by the 5G base station. The second is to use the channel reciprocity of TDD to evaluate the downlink quality based on the measurement of the user uplink level and quality, and to support the allocation of TDD downlink weights. In TDD mode, the uplink and downlink channels use the same spectrum. By obtaining the level and quality of the UE SRS signal, the characteristics of the downlink channel can be estimated, and then the downlink signal of the PDSCH is weighted, that is, the SRS weight. In FDD, the uplink and downlink channels use different spectra, and the weighting is mainly based on the PMI (Precoding Matrix Indicator) weight. There is no SRS weight, and the SRS in the FDD mode is only used for uplink signal level measurement. Therefore, if the purpose is to improve the throughput on the 5G base station side and better use the channel reciprocity of TDD to evaluate the downlink quality, it is necessary to consider configuring different SRS periods for the TDD mode. However, the existing technology does not distinguish between the TDD mode and the FDD mode of 5G.

[0040] Different users have different requirements for wireless throughput. Users with high wireless throughput requirements generate a larger number of RLC (Radio Link Control) bytes within a set time period, requiring better beamforming from the 5G base station, that is, a higher Rank = 4 ratio is required. Users with low wireless throughput requirements do not require the 5G base station to provide better beamforming effects. Depending on their actual needs, physical layer transmission with Rank = 1 or Rank = 2 can meet their needs. Therefore, different SRS periods need to be configured for 5G users with different RLC byte requirements.

[0041] Existing 5G networks operate in a multi-user environment, where different users' locations change at varying speeds. For users with high wireless throughput requirements and rapidly changing locations, a shorter SRS period is required to quickly track changing channel conditions and provide more accurate measurement information. If multiple users within a 5G base station share these characteristics, a shorter SRS period than the default should be configured for each user. This ensures more accurate downlink channel weight estimation, increases the proportion of these users with a Rank = 4, and thus improves the overall throughput of the 5G base station.

[0042] In an embodiment of the present invention, in order to solve the technical problem that all terminal devices under a 5G base station use the same SRS period, resulting in poor downlink throughput of the terminal device, a detection period configuration method for a terminal device is provided. Figure 1 , Figure 1 1 is a flowchart of a method for configuring a detection period of a terminal device provided by an embodiment of the present invention, wherein the method for configuring a detection period of a terminal device includes:

[0043] S1. When detecting that a target terminal resides within the coverage of a first base station, sending a measurement control instruction to the target terminal;

[0044] S2. Receive a neighboring cell measurement result sent by the target terminal, and when a second base station whose signal level exceeds a preset signal threshold is present in the neighboring cell measurement result, send instruction information for switching connection to the second base station to the target terminal;

[0045] S3. After the target terminal is connected to the second base station, obtain a sounding reference signal of the target terminal;

[0046] S4. When it is determined that the target terminal meets the preset non-weak coverage condition based on the detection reference signal, obtain the standard detection period currently configured by the second base station for the terminal device, and instruct the second base station to configure the detection period of the target terminal as the target detection period; wherein the target detection period is less than the standard detection period.

[0047] It is worth noting that the detection period configuration method of the terminal device described in the embodiment of the present invention can be implemented by a monitoring platform independent of the first base station and the second base station (in this case, there is no need to make program or hardware changes to the first base station and the second base station). The monitoring platform should have the ability to communicate with the first base station, the second base station and the terminal device, as well as the function of configuring the detection period of the terminal device. Alternatively, the above steps S1 to S2 are implemented by the first base station, and after the target terminal switches and connects to the second base station, the above steps S3 to S4 are implemented by the second base station.

[0048] Specifically, before executing step S1, the method also includes: collecting the cumulative number of bytes of the wireless link control of the terminal device residing in the first base station within a preset time period; when the cumulative number of bytes is greater than the preset byte number threshold, determining that the terminal device is a target terminal that meets the throughput requirement condition; when the cumulative number of bytes is less than or equal to the byte number threshold, determining that the terminal device is a device that does not meet the throughput requirement condition.

[0049] For example, under normal circumstances, 5G terminals are connected to the base station through the Attach process and are identified by the network. They will then continue to reside in the public network base station. The base station is the basic unit that constitutes the cellular cell in mobile communications. It mainly completes the communication and management functions between the mobile communication network and mobile communication users. In a narrow sense, the base station can be understood as a radio transceiver station. In other words, mobile phone signals, the ability of mobile phones to access the Internet and make calls are all because the UE (5G terminal) resides on a base station and is within the coverage of the base station signal. To determine whether the terminal device resides in the NR FDD base station, it can be determined by the center frequency point number of the NR cell where the terminal device resides. The frequency bands, site center frequencies, and center frequencies corresponding to the center frequencies involved in base stations with different networking modes are different. Therefore, whether the terminal device resides in the NR FDD base station is determined based on the detection of the center frequency point number of the terminal device. When it is detected that a terminal device is residing within the coverage of the first base station, the cumulative number of bytes of the radio link control (RLC) of the terminal device is collected within a preset time period (such as T0); when the cumulative number of bytes within T0 is greater than the byte number threshold, it indicates that the terminal device has a large demand for wireless throughput, and the terminal device is marked as a target terminal at this time; when the cumulative number of bytes within T0 is less than or equal to the byte number threshold, it indicates that the terminal device has a small demand for wireless throughput, and the terminal device is not processed at this time.

[0050] In the embodiment of the present invention, since the terminal device needs to establish multiple RLC connections with the base station before sending packet data packets through the wireless link, by detecting the number of RLC bytes accumulated by the terminal device over a period of time, it is possible to accurately determine whether the terminal device is a device with a large throughput demand.

[0051] Specifically, in step S1, when it is detected that a target terminal resides within the coverage of the first base station, a measurement instruction is sent to the target terminal. The measurement instruction may include an indication of what kind of measurement the target terminal should perform, such as the measurement instruction is used to instruct the target terminal to initiate an A2 measurement to measure whether there is a second base station operating in NRTDD mode in the neighboring area. Exemplarily, the measurement events that can be executed by the UE include multiple, such as A1 measurement event, A2 measurement event, A3 measurement event, A4 measurement event, A5 measurement event, A6 measurement event, B1 measurement event and B2 measurement event, etc. In the embodiment of the present invention, the target terminal selects A2 measurement to measure the neighboring area. The A2 event indicates that the serving cell is worse than the absolute threshold, which can be used to start measurements between certain cells. After the event occurs, operations such as switching may occur.

[0052] Specifically, in step S2, the neighboring cell measurement result sent by the target terminal is received. When there is a second base station in the neighboring cell in the neighboring cell measurement result whose signal level exceeds the preset signal threshold, and the second base station operates in NR TDD mode, it means that the signal coverage of the second base station is strong. The target terminal can switch to connect to this second base station. At this time, indication information of switching to the second base station is sent to the target terminal.

[0053] Exemplarily, the first base station (or monitoring platform) sends a measurement control measConfig to the target terminal. The measurement control is sent to the target terminal in the form of measId. Each measId includes two elements: measObjectId and reportConfigId. These two elements are at the beginning of the same measConfig. That is, the first base station (or monitoring platform) compiles a table of measurement and control messages, and the target terminal directly sends this ID. When the first base station (or monitoring platform) receives the ID, it knows which measurement event it corresponds to. The target terminal measures the "surrounding cells" according to the specified RAT (Radio Access Technology) frequency based on the received measurement control (this cell will be measured and reported even if it is not configured in the neighboring cell list of the serving cell) and reports according to the measurement event configuration. After the first base station (or monitoring platform) receives the MR (Measurement Report) measurement report, it prepares for switching according to the decision threshold and the neighboring cell configuration and executes the switching. For example, if the frequency and PCI of the neighboring cell reported by the target terminal match a neighboring cell in the neighboring cell, the subsequent switching preparation will be triggered, and then the target terminal will switch to the selected second base station.

[0054] Specifically, in step S3, after the target terminal is connected to the second base station, a sounding reference signal of the target terminal is acquired.

[0055] Specifically, after obtaining the sounding reference signal of the target terminal, the method also includes: obtaining the reference signal receiving power and signal-to-noise ratio in the sounding reference signal; when the reference signal receiving power is greater than a preset receiving power threshold, and the signal-to-noise ratio is greater than a preset ratio threshold, determining that the target terminal meets the non-weak coverage condition; when the reference signal receiving power is less than or equal to the receiving power threshold, or the signal-to-noise ratio is greater than or equal to the ratio threshold, determining that the target terminal does not meet the non-weak coverage condition.

[0056] Exemplarily, weak coverage generally means that the signal strength in the coverage area can no longer meet the normal communication requirements. For example, the signal level value is less than -85 dbm. There are many reasons for weak coverage, mostly due to geographical location, shielding environment, obstacle blockage, etc. in the area. Non-weak coverage means that the signal strength in the coverage area can meet the normal communication requirements. For a target terminal in a weak coverage scenario, it can no longer communicate normally by itself, so there is no need to adjust the detection period anymore. Therefore, in the embodiments of the present invention, it is necessary to determine whether the terminal device is in a non-weak coverage scenario. The Reference Signal Receiving Power (RSRP) is one of the key parameters representing the wireless signal strength and the physical layer measurement requirements in the LTE (Long Term Evolution) network. It is the average value of the signal power received on all RE (resource particles) carrying the reference signal within a certain symbol. The Signal to Interference plus Noise Ratio (SINR) is the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). In the embodiments of the present invention, by evaluating these two parameter values of the reference signal receiving power and the signal to interference plus noise ratio, it is determined whether the target terminal is in a non-weak coverage scenario. When the reference signal receiving power is greater than the received power threshold and the signal to interference plus noise ratio is greater than the ratio threshold, it is determined that the detection reference signal meets the non-weak coverage condition, and the corresponding target terminal is in a non-weak coverage scenario. Otherwise, the target terminal is in a weak coverage scenario. It should be noted that the specific values of the received power threshold and the ratio threshold can be set according to empirical values and are not specifically limited herein.

[0057] Specifically, in step S4, when the target terminal meets the preset non-weak coverage condition, obtain the standard detection period currently configured by the second base station for the terminal device, that is, collect the current SRS period P0 of the NR TDD base station, and then instruct the second base station to configure an SRS period P1 smaller than the current P0 period for the target terminal, so that P1 < P0. Exemplarily, the second base station can send the SRS configuration period to the target terminal through RRC (Radio Resource Control) signaling.

[0058] Specifically, after step S4 is executed, the method further includes: when it is determined according to the detection reference signal that the target terminal does not meet the non-weak coverage condition, instruct the second base station to configure the target detection period of the target terminal as the standard detection period P0.

[0059] In an embodiment of the present invention, a smaller SRS period is set for 5G terminals with large throughput requirements, so as to increase the proportion of Rank=4 of the 5G terminals, that is, to increase the downlink throughput of the terminals; for users with large wireless throughput requirements and rapid location changes, a smaller SRS period is set for the 5G terminals, so that the 5G terminals can report detection signals and strengths more quickly, which can enable the 5G base station to track changes in channel conditions more quickly, perform beamforming more accurately, and improve the downlink throughput of the 5G terminals; if multiple users under the 5G base station meet such characteristics, it is necessary to configure an SRS period smaller than the default SRS period for such users, so that the weight estimation of the downlink channel is more accurate, and the proportion of Rank=4 of such users is increased, thereby improving the overall throughput of the 5G base station.

[0060] Specifically, the method further includes: after configuring a target detection period of the target terminal once, respectively obtaining the four-stream transmission ratios of the second base station before and after configuring the target detection period; when the four-stream transmission ratio of the second base station after configuring the target detection period is greater than the four-stream transmission ratio of the second base station before configuring the target detection period, maintaining the current target detection period of the target terminal unchanged; when the four-stream transmission ratio of the second base station after configuring the target detection period is less than or equal to the four-stream transmission ratio of the second base station before configuring the target detection period, configuring the detection period of the target terminal to be the detection period before performing the configuration operation.

[0061] Exemplarily, the four-stream transmission ratio is the ratio of the number of downlink transmission bytes to the total number of transmission bytes when the number of spatial division multiplexing streams of the second base station is four streams, that is, the ratio of Rank=4. Since NR FDD cannot use SRS for uplink channel estimation, it is impossible to use SRS weights for downlink beamforming. Therefore, when a 5G terminal with large bandwidth service requirements resides in an NR TDD cell, it is necessary to determine the SRS period of the NR TDD cell and, if permitted, reduce the SRS period to improve the throughput of the 5G terminal. Feedback is then provided by counting the RANK=4 ratio to further adjust the SRS period of the 5G terminal. The ratio of Rank=4 under the NR TDD base station is collected to determine whether the indicator has improved compared to the ratio of Rank=4 before the detection period is configured. If so, the SRS period parameter modification is retained and the current target detection period of the target terminal remains unchanged. Otherwise, the parameter is rolled back and the detection period of the target terminal is configured to be the detection period before the configuration operation is performed.

[0062] It's worth noting that the Rank 4 ratio reflects the utilization of four streams during physical layer transmission. It's expressed as the ratio of the number of TB used in downlink transmission using Rank 4 to the total number of TB transmitted. The metric is defined as follows: Rank 4 ratio = 4-stream downlink TB / (1-stream downlink TB + 2-stream downlink TB + 3-stream downlink TB + 4-stream downlink TB) * 100%.

[0063] In wireless communication systems, RANK simply means that the same time-frequency resources are divided into several parts in space and transmitted simultaneously. Codewords are mapped to each stream through layer mapping (number of codewords ≤ number of streams ≤ number of antenna ports). Given a fixed time-frequency resource, a higher RANK indicates higher actual throughput. Theoretically, 5G base stations support 16 downlink streams (layers) and 8 uplink streams (layers), while 5G terminals support a maximum of 4 downlink streams (layers) and 2 uplink streams (layers). Therefore, in non-weak coverage scenarios, a downlink Rank = 4 ratio can be used to represent the downlink throughput of a 5G terminal. The rank of a transmission channel can be thought of as the number of independent parallel channels in the transmission path between transceivers, which can be understood as relatively independent data paths supported simultaneously. The number of data streams actually used in MIMO transmission is called the number of layers. Because the orthogonality of data paths varies across different MIMO channels, interference between data streams must be considered in practical applications. When using multiple antennas to transmit multiple codewords, the number of data streams (i.e., layers) that can be sent simultaneously must be determined based on the rank of the spatial channel to reduce interference between signals, increase reception accuracy, and improve information transmission capacity.

[0064] In this embodiment of the present invention, after configuring the target terminal's detection period, the actual downlink throughput of the target terminal is reflected by detecting whether the ratio of the two configured Rank = 4 increases. If the ratio of Rank = 4 increases, it indicates that the target terminal's downlink throughput is greater than the downlink throughput after the last configured detection period. Therefore, the target terminal's detection period is maintained unchanged. Otherwise, the detection period is rolled back. Through the above adjustment method, the target terminal can meet its high throughput requirements.

[0065] Specifically, the method also includes: after configuring the target detection period of the target terminal, if the target terminal still meets the throughput requirement condition, reducing the target detection period of the target terminal until the target terminal does not meet the throughput requirement condition or the target detection period is equal to a preset minimum detection period.

[0066] Exemplarily, reset T0, re-judge the 5G terminal with the SRS period set to P1, denoted as S1, and continue to collect the cumulative number of bytes of the radio link control (RLC) of the 5G terminal marked as S1 within the time period T0. If the 5G terminal with the SRS period set to P1 still meets the throughput requirement condition, set the SRS period of this terminal to P2, where P2 < P1, until the 5G terminal does not meet the throughput requirement condition or the SRS period of the target terminal drops to the lowest detection period that the second base station can configure.

[0067] In an embodiment of the present invention, after configuring the detection period of the 5G terminal, continue to determine whether this terminal device is a device with a large throughput requirement by detecting the RLC bytes of the 5G terminal within a period of time. When the throughput requirement of the 5G terminal is still large, continuously adjust the detection period of the 5G terminal to make it meet the large throughput requirement.

[0068] Compared with the prior art, the method for configuring the detection period of the terminal device disclosed in the present invention, when detecting that a target terminal meeting the throughput requirement condition stays within the coverage range of the NR FDD base station, sends an indication message to switch the connection to the NR TDD base station to the target terminal. After the target terminal connects to the NR TDD base station, obtain the detection reference signal of the target terminal. When the detection reference signal meets the non-weak coverage condition, obtain the standard detection period currently configured by the NR TDD base station and configure the target detection period of the target terminal to be less than the standard detection period. By setting a smaller detection period for the target terminal, the beamforming effect of the base station is better, the downlink transmission rate of the target terminal is improved, and thus the downlink throughput of the target terminal is improved. Since the throughput requirements of different terminal devices are considered in the NR TDD and NR FDD hybrid networking mode, and the SRS detection period is configured on demand, the downlink throughput of the terminal device can be effectively improved.

[0069] See Figure 2 , Figure 2 is a structural block diagram of a detection period configuration device 100 for a terminal device provided by an embodiment of the present invention. The detection period configuration device 100 for the terminal device includes:

When the detection reference signal meets the non-weak coverage condition, the standard detection period currently configured by the NR TDD base station is obtained and the target detection period of the target terminal is configured to be smaller than the standard detection period.
