Background technique

Faced with the growing mobile broadband business, single carrier transmission has gradually failed to meet the demand, and the spectrum resources owned by operators are relatively scattered. In order to effectively use the spectrum resources, operators and equipment manufacturers are strongly promoting carrier aggregation technology (Carrier Aggregation, Referred to as CA). CA can aggregate multiple LTE frequency band carrier units (Component Carrier, CC for short) together, which is a technology to increase transmission bandwidth. It can achieve a maximum transmission bandwidth of 100MHz, effectively increasing the uplink and downlink transmission rates. In carrier aggregation, it includes a primary carrier (Primary component carrier, PCC) and at least one secondary carrier (Secondary component carrier, SCC).

Although carrier aggregation brings huge advantages in transmission broadband, carrier aggregation is not advantageous in any case, because when the mobile terminal is in carrier aggregation mode, if the mobile terminal carrier unit shares an antenna, the carrier When the aggregation mode works, the antenna can only tune a certain frequency band in the carrier aggregation, that is, select a certain frequency band to tune between the main carrier frequency band and each auxiliary carrier frequency band. This tuned antenna frequency band is preset in the software according to the research and development needs. In the code, it can generally be set to PCC or a certain SCC. This will inevitably degrade the performance of the antenna, especially when the set carrier signal is weak, the main carrier and the auxiliary carrier will not work properly, resulting in network problems such as network disconnection, poor signal, and low throughput.

detailed description

In order to make the purpose, technical solutions and advantages of the disclosure more clear, the disclosure will be further described in detail below through specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

Example one:

In order to solve the problem that the antenna in the carrier aggregation mode (especially for a single antenna setting) can only be tuned to a certain frequency band set in advance, which may cause the performance of the antenna to deteriorate, which is not conducive to taking advantage of the high bandwidth of carrier aggregation; B5 + B3 downlink dual carrier aggregation, under the condition of CA configured in the software code, the antenna tuning state is set according to PCC, that is, when B5 + B3CA works, the antenna state is tuned to PCC B5 state, especially in actual work, if At this time, the signal received by B5 in the cell is weak, and at the same time, the signal of B3 in this cell is strong. At this time, the actual user experience (such as signal strength, throughput, dropped calls, etc.) of CA using B5 tuning state is not used. The performance of CA in the B3 tuning state is good. The present disclosure provides an antenna tuning method, which can realize the adaptive selection of the tuning frequency band and achieve the purpose of improving the antenna performance during carrier aggregation as much as possible.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of an antenna tuning method according to an embodiment of the present invention. The antenna tuning method includes at least the following steps:

S101. When the carrier aggregation mode works, detect the received signal strength of each carrier unit to be tested currently on the terminal; the carrier unit to be tested includes at least part of the carrier units currently configured by the terminal, and the at least part of the carrier units includes a primary carrier Unit and at least one auxiliary carrier unit.

Currently, the terminal can support at least the following two transmission modes. One is the traditional single-carrier transmission mode, which is equivalent to signal transmission through one carrier unit; the other is the carrier aggregation mode, which is equivalent to multiple (up to 5 ) The carrier units are aggregated together to take advantage of the cumulative bandwidth of multiple carrier units to achieve a transmission bandwidth of up to 100 MHz and increase the transmission rate.

The aggregation of carrier elements includes a primary carrier element and at least one (up to 4) secondary carrier elements. The cell corresponding to the primary carrier unit is the primary serving cell (PCell) of the terminal. The primary serving cell is the cell at the initial access of the terminal and is responsible for RRC (Radio Resource Control) communication with the terminal. The cell corresponding to the secondary carrier unit is the secondary serving cell (SCell) of the terminal, and the secondary serving cell is added during RRC reconfiguration to provide additional wireless resources.

Different carrier units may have different identifiers, for example, the primary carrier unit is marked with "0", the secondary carrier is marked with "1", "2", "3", "4", etc. Of course, it is not limited to this example.

The terminal can detect whether the current carrier aggregation mode works (or starts), or whether it works in the carrier aggregation mode. The method for detecting whether the terminal is working in the carrier aggregation mode may adopt any existing method, and is not limited herein.

When the carrier aggregation mode works, the terminal detects the received signal strength (Receive signal strength) (RSSI) of each carrier unit to be tested currently configured. The method for detecting the strength of the received signal may use any existing method, which is not limited herein.

The carrier unit to be tested includes at least part of the carrier units currently configured by the terminal, and the at least part of the carrier units includes a primary carrier unit and at least one secondary carrier unit. For example, the terminal is currently configured with a primary carrier unit PCC1 and three secondary carrier units, namely SCC1, SCC2, and SCC3. At least one secondary carrier unit can be selected as the carrier unit under test according to the actual needs of the current carrier aggregation (of course, it must be Including the primary carrier unit PCC1), for example, SCC1, SCC2, and SCC3 are selected as carrier units to be tested.

Taking dual carrier aggregation as an example, the terminal is currently configured with a primary carrier unit and a secondary carrier unit. When the carrier aggregation mode is determined to work, the received signal strength (assumed to be P1) of the frequency band where the primary carrier unit is located is detected, and the secondary carrier The received signal strength of the frequency band where the unit is located (assumed to be P2).

S102. Compare the received signal strength of each carrier unit to be tested with a preset list, and select a tuning frequency band that matches the received signal strength of the carrier unit to be tested as the target tuning frequency band; the preset list includes different carriers combined in different received signals Corresponding to the best tuning frequency band under the intensity, the best tuning frequency band is based on the performance simulation results of the carrier aggregation of the terminal.

The preset list includes the mapping relationship between different carrier combinations under different received signal strengths and the best tuning frequency band. This mapping relationship is obtained based on the performance simulation of the terminal antenna, that is, different carrier combinations under different received signal strengths The best tuning frequency band is based on the performance simulation of the terminal antenna. Among them, the performance of the terminal antenna includes but is not limited to throughput, call drop rate, signal strength, etc. Taking throughput as an example, that is, different carrier combinations under different received signal strengths are simulated using different tuning bands to obtain the maximum throughput, and the tuning band corresponding to the maximum throughput is the best tuning Frequency band.

See the example of the preset list shown in Table 1 below:

Table 1

As shown in the table above, for the carrier combination of PCC and SCC1, under different received signal strengths, the corresponding optimal tuning frequency band can be obtained through debugging simulation. In the case of PCC> rssi1 and SCC1 <rssi2, the corresponding optimal tuning band is PCC, that is, the antenna can be tuned to the PCC band to achieve the best performance; in the case of PCC <rssi3 and SCC1> rssi4, the corresponding The best tuning band is SCC1, that is, the antenna can be tuned to the SCC1 band to achieve the best performance; in the case of PCC <rssi5 and SCC1 <rssi6, the corresponding best tuning band is SCC1, that is, the antenna can be tuned to the SCC1 band To achieve the best performance.

It should be understood that the above Table 1 only shows a carrier combination (dual carrier combination) of PCC and SCC1. In practical applications, it is entirely possible that there are multiple carrier combinations. It includes but is not limited to at least one of a three-carrier combination, a four-carrier combination, and a five-carrier combination.

Please refer to the following Table 2, which is an example of three-carrier combination:

Table 2

The preset list can include multiple forms of dual-carrier combination, triple-carrier combination, quad-carrier combination, and 5-carrier combination. Taking dual-carrier and triple-carrier as an example, please refer to the example shown in Table 3:

table 3

Compare the received signal strength (the primary carrier is P1 and the secondary carrier is P2) with the preset list. Assuming that P1 is greater than rssi1 and P2 is less than rssi2, you can determine its combination with the preset list 1 ( PCC> rssi1, SCC1 <rssi2) match, at this time it can be determined that the corresponding tuning frequency band is the PCC frequency band. Therefore, the PCC frequency band is used as the target tuning frequency band.

S103. Tuning the antenna of the terminal according to the target tuning frequency band.

Optionally, the terminal line is tuned to the target tuning frequency band for data transmission and reception.

The present disclosure is mainly applied in the use of mobile terminals, and solves the problem that the same antenna can only be tuned in a certain frequency band under the carrier aggregation working state, and cannot meet the tuning performance of all carrier frequencies at the same time, especially when the set carrier signal is weak In the case of, by detecting the actual network parameter status under the current network, matching the preset list to obtain the best tuning frequency band obtained through debugging simulation, so as to ensure that the antenna is switched in the best state. Maximize the efficiency of the combined antenna and maximize the user experience.

The antenna tuning method provided in the present disclosure is mainly applicable to a single antenna terminal, and dynamically adjusts the tuning frequency band by detecting the real-time network parameters (received signal strength) of each carrier unit to achieve the best performance of the antenna and realize the single antenna to carrier aggregation Adaptive tuning. It should be understood that this solution is also applicable to multi-antenna terminals.

In other examples of the present disclosure, when there is no tuning frequency band matching the received signal strength of the carrier unit under test, the tuning frequency band can be determined by comparing the received signal strength of each carrier unit under test and selecting the received signal strength The largest carrier unit to be tested is used as the target carrier unit, and the antenna of the terminal is tuned to the frequency band where the target carrier unit is located.

For example, at a certain moment, it is detected that the received signal strength of the carrier unit under test PCC is P3, and the received signal strength of SCC is P4. Compare PCC = P3 and SCC = P4 with a preset list (assuming Table 1) to determine P3 It is neither greater than rssi1, nor less than rssi3 and rssi5, that is, there is no carrier combination matching PCC = P3 and SCC = P4, and the optimal tuning frequency band cannot be determined according to the preset list at this time. Here, the size of P3 and P4 can be compared. If P3 is less than P4, then SCC is used as the target carrier unit, so that the terminal antenna is tuned to the frequency band where SCC is located; if P3 is greater than P4, PCC is used as the target carrier unit, And control the terminal to tune the antenna to the frequency band where the PCC is located. The received signal strength obtained through real-time detection determines a larger carrier unit to be tested, and the antenna is tuned to the frequency band of the carrier unit to be tested with a higher received signal strength, which is beneficial to ensure the transmission performance of carrier aggregation and improve user use as much as possible Experience.

S306. Select a fixed tuning frequency band set by default for tuning.

If it is judged according to the instruction information that it is not working in the CA state, select the current single carrier to tune; if it is judged according to the instruction information that it is working in the CA state, but does not match the corresponding best tuning frequency band, the default value is selected from each carrier unit under test The fixed tuning frequency band (for example, the frequency band where the main carrier unit in each carrier unit to be tested is located) is used to adjust the antenna state.

The present disclosure makes the antenna work in the best state by judging whether RSSI satisfies the pre-stored CA preset list in different scenarios, improves antenna efficiency, reduces network problems such as dropped network, poor signal, low throughput, etc. User satisfaction, at the same time, there is no need to install multiple antennas to achieve CA tuning, which reduces the cost of the device and facilitates the layout of the solution.
