[0052] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0053] For the frequency division duplexing (FDD) band, the frequencies of the uplink channel and the downlink channel are separated. The passive efficiency of the antenna is often uneven in the entire bandwidth, and there may be multiple situations such as higher efficiency at low frequencies or higher efficiency at high frequencies. By adjusting the state of the antenna tuner (tunecode), the matching state of the antenna can be changed, thereby optimizing the efficiency of the antenna at different frequencies.

[0054] Figure 1 A schematic diagram of the relationship between antenna state and antenna efficiency provided in an embodiment of the present application is shown in FIG. Figure 1 As shown in the figure, in tunecode0 state, the antenna efficiency is higher at low frequencies, that is, the uplink channel efficiency is better than the downlink channel efficiency. When switching to tunecode1, the antenna efficiency is higher at high frequencies, that is, the downlink channel efficiency is better than the uplink channel efficiency. It should be noted that for the frequency band of time division duplexing (TDD), since the frequencies of uplink and downlink transmissions are the same, the above problem does not exist.

[0055] The antenna efficiency is different at the uplink transmission frequency and the downlink transmission frequency. In certain scenarios, the downlink energy efficiency is poor, resulting in a weak downlink signal, and the terminal will be disconnected from the network and lose service.

[0056] To address this problem, the present application provides a service-based antenna adjustment method. Figure 2 The following is a flow chart of a service-based antenna adjustment method provided in an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0057] Step 101, configuring multiple antenna tuning schemes;

[0058] In this embodiment, there are both uplink transmission and downlink transmission in the antenna service, but different services have different focuses. For example, for the service of uploading files, the efficiency of uplink transmission is more important; for the service of downloading files, the efficiency of downlink transmission is more important. The difference between the center frequency of the downlink channel and the center frequency of the uplink channel at the same frequency point is close to 100MHz. In order to adapt the antenna to different services, this solution sets different antenna tuning schemes by testing the optimal impedance of the antenna at different frequencies. The frequency bands with higher antenna efficiency in different schemes are different, such as the uplink frequency antenna efficiency is higher or the downlink frequency antenna efficiency is higher.

[0059] Step 102: determine a service state according to signal transmission related data, and select a target tuning scheme from the antenna tuning schemes according to the service state.

[0060] In this embodiment, the service status is determined based on a variety of judgment criteria, and the service status reflects whether the current service focuses on uplink transmission or downlink transmission. It includes: uplink priority status and downlink priority status. If it is in the uplink priority status, it means that the current service focuses on uplink transmission, and the antenna needs to be adjusted to improve the efficiency of the antenna in the uplink transmission frequency band; if it is in the downlink priority status, it means that the current service focuses on downlink transmission, and the antenna needs to be adjusted to improve the efficiency of the antenna in the downlink transmission frequency band. Improving the antenna transmission efficiency is specifically achieved by selecting a target tuning scheme whose center frequency matches the frequency corresponding to the current service from the antenna tuning scheme, and adjusting the antenna impedance according to the target tuning scheme.

[0061] Step 103: adjusting the operating state of the antenna according to the target tuning scheme.

[0062] This embodiment provides another service-based antenna adjustment method. Figure 3 The following is a flow chart of a service-based antenna adjustment method provided in an embodiment of the present application. Figure 3 As shown, Figure 2Step 102 of determining the service status according to the signal transmission related data may include the following steps:

[0063] Step 201a, determining the type of the foreground application, if the type of the foreground application is an upload application, determining that the service state is an uplink priority state;

[0064] Step 201b: if the type of the foreground application is a download application, determining that the service state is a downlink priority state;

[0065] Step 201c: if the type of the foreground application is other, determine the service status according to the operation frequency.

[0066] In this embodiment, the signal transmitted by the antenna serves the foreground application, and its type is determined according to the identifier corresponding to the foreground application, or the type corresponding to the foreground application is pre-stored in a database, the foreground application is identified and the corresponding type is retrieved from the database.

[0067] Optionally, determining the service state according to the operating frequency includes:

[0068] Step 202a, determining the uplink operating frequency and the downlink operating frequency of the foreground application, and if the uplink operating frequency is higher than a preset frequency threshold, determining that the service state is an uplink priority state;

[0069] Step 202b: otherwise, determine the service status according to the size of the data flow.

[0070] In this embodiment, the uplink or downlink operating frequency reflects the service demand for uplink or downlink transmission. If the uplink operating frequency is greater than a certain operating frequency threshold, it means that the foreground application has a high demand for uplink transmission, and the service status can be determined as the uplink priority status.

[0071] In a possible embodiment, the operation frequency threshold is 10 times / s.

[0072] Optionally, determining the service status according to the size of the data flow includes:

[0073] Step 203a, if the uplink data flow is greater than the downlink data flow, and the difference between the uplink data flow and the downlink data flow is greater than a preset flow threshold, determining that the service state is an uplink priority state;

[0074] Step 203b, if the downlink data flow is greater than the uplink data flow, and the difference between the uplink data flow and the downlink data flow is greater than a preset flow threshold, determining that the service state is a downlink priority state;

[0075] Step 203c: otherwise, determine the service status according to the duty cycle.

[0076] In this embodiment, data flow refers to the amount of data transmitted in a computer network, usually the number or size of data packets passing through the network within a period of time. It can be an indicator used to measure the usage and load of the network. Based on the data flow, the performance of the network can be analyzed and the resource usage can be monitored.

[0077] When the uplink data traffic is greater than the downlink data traffic, it means that the service has a higher demand for uplink transmission efficiency and a lower demand for downlink transmission efficiency, and the difference between the uplink data traffic and the downlink data traffic is greater than the preset traffic threshold, which means that the current service has a much greater demand for uplink transmission than downlink transmission, so the service status is uplink priority.

[0078] In a possible embodiment, the traffic threshold is 20 Mbps.

[0079] Optionally, determining the service state according to the duty cycle includes:

[0080] Step 204a, if the duty cycle of the uplink transmission is greater than a preset duty cycle threshold, and the duty cycle of the downlink transmission is less than the preset duty cycle threshold, determining that the service state is an uplink priority state;

[0081] Step 204b, if the duty cycle of the downlink transmission is greater than the preset duty cycle threshold, and the duty cycle of the uplink transmission is less than the preset duty cycle threshold, determining that the service state is a downlink priority state;

[0082] Step 204c: otherwise, determine the service status according to the power headroom.

[0083] In this embodiment, the network allocates a certain amount of physical resources to the terminal, and the duty cycle is the ratio of the resources used by the terminal to the total amount of resources allocated by the network.

[0084] For example, the network allocates a data transmission speed of 1M to the terminal, and the terminal only has 800K of data to transmit, and the rest will be sent in the form of padding packets. The duty cycle is the ratio between the actual transmitted data 800k and the overall transmitted data 1M.

[0085] For uplink transmission, if the resources allocated by the network are completely occupied and there are no empty padding packets, it means that the service has a high demand for uplink transmission, but the uplink resource authorization is not sufficient, and the efficiency of uplink transmission needs to be improved.

[0086] For downlink transmission, if the resources allocated by the network are completely occupied and there are no empty padding packets, it means that the service has a high demand for downlink transmission, but the downlink resource authorization is not sufficient, and the efficiency of downlink transmission needs to be improved.

[0087] Optionally, determining the service state according to the power headroom includes:

[0088] Step 205a, if the power headroom is less than a preset power threshold, determining that the service state is an uplink priority state;

[0089] Step 205b: If the power headroom is greater than or equal to a preset power threshold, determining that the service state is a downlink priority state.

[0090] In this embodiment, the terminal and the network will negotiate a maximum transmit power. The power transmitted by the terminal cannot exceed this threshold. The power margin refers to the difference between the actual power of the terminal and the maximum power. The larger the difference, the more power can be increased. If the power margin is sufficient, it means that the uplink can be improved by increasing the transmit power, and it is not necessary to enhance the uplink transmission efficiency.

[0091] In a possible embodiment, the flow power margin is 20 Mbps.

[0092] This embodiment provides another service-based antenna adjustment method. Figure 2 Step 102 selects a target tuning scheme from the antenna tuning schemes according to the service state, including:

[0093] If the service state is an uplink priority state, obtaining an uplink channel center frequency, and determining an antenna tuning scheme corresponding to the uplink channel center frequency as a target tuning scheme;

[0094] If the service state is a downlink priority state, a downlink channel center frequency is acquired, and an antenna tuning scheme corresponding to the downlink channel center frequency is determined as a target tuning scheme.

[0095] In this embodiment, the terminal simultaneously determines the status of the uplink and downlink channels and the uplink and downlink bidirectional needs of the service, and only performs impedance adjustment through the antenna tuning scheme when the enhancement on one side (for example, the downlink) is beneficial and the corresponding impairment on the other side (for example, the uplink) is acceptable or compensable.
