Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before the content of the embodiments of the present disclosure is described, an application scenario of the present disclosure is described first, and the present disclosure may be applied to a terminal having a communication function, such as a mobile phone. When the mobile phone is used, the receiving path of the communication module of the mobile phone is interfered by other modules of the mobile phone, especially by digital circuits, such as a screen and a camera, and when the modules operate, the receiving path of the communication module is interfered, so that the receiving sensitivity is deteriorated, which is also called as sense.
In order to solve the above-described problem, a technique of performing auxiliary reception by diversity (simply referred to as a diversity reception technique) that is multi-path connection may be employed to improve performance such as communication sensitivity. That is, when the received signal strength of the primary set deteriorates to a certain extent, diversity is turned on to receive signals together with the primary set.
The diversity receiving technology is a main anti-fading technology at present, and can greatly improve the reliability under the transmission of a multipath fading channel, the basic idea of the diversity receiving technology is that a base station separates multipath signals into uncorrelated (independent) multipath signals, and a receiving end (such as a terminal) can combine the energy of the multipath signal separation signals according to a certain rule through diversity arranged on the receiving end, so that the energy of received useful signals is maximized, and the signal-to-noise ratio of the received signals is further improved.
For a terminal, a main set and a diversity may be understood as two sets of hardware on the terminal, each set including two antennas, the main set including antennas responsible for transmission and reception of radio frequency signals, and the diversity including antennas responsible for reception but not transmission. In general, the terminal receives and transmits signals through the primary set, and after the terminal turns on diversity, the terminal may perform the above-mentioned combining processing on the signals received from the primary set and the diversity, so that the terminal may obtain the gain provided by diversity (where the gain provided by diversity is a reception gain), thereby implementing the reception of signals through the diversity-assisted primary set. The terminal can counteract the influence of fast fading on the received signal by adopting the diversity reception technology.
To sum up, this disclosure can avoid under the not good condition of communication signal received strength, all open the problem that worsens more of the signal received strength that leads to with two routes of main set and diversity simultaneously, can confirm whether to adopt the communication mode of opening the diversity according to current communication state and diversity state, can promote the reception performance at terminal.
Fig. 1 is a flow chart illustrating a method of communication according to an exemplary embodiment, the method comprising the steps of, as shown in fig. 1:
in step 101, when the received signal strength of the primary set of the terminal is less than a preset signal strength threshold, current communication status information and status information of diversity of the terminal are acquired.
For example, the terminal may be a terminal having a communication function, such as a mobile phone, a tablet computer, and the like, and when the degree of deterioration of the received signal strength of the main set satisfies a certain condition and the diversity is ready to be turned on for synchronous reception of signals, it is necessary to determine whether the diversity is turned on and then the received signal strength of the signals is further deteriorated according to the current communication state information, so as to determine whether to turn on the diversity for multi-channel reception.
The communication state information includes a currently occupied channel or a current first error rate, the diversity state information includes a channel set in which a pre-recorded diversity has a receiving sensitivity deterioration condition, or may be a second error rate, the second error rate is an error rate obtained when a designated communication gap opens diversity, and the communication gap includes: time gaps in which no data is transmitted during the current communication.
Illustratively, when the terminal determines that there is no data packet to be received and transmitted in a future time period (generally, according to a communication protocol, it can know when the terminal transmits data and does not transmit data), the time period can be understood as the communication gap, so that diversity can be started in the communication gap period, and the error rate at this time can be determined as the second error rate on the basis of not influencing the current communication. Or, for a terminal adopting a full duplex communication technology such as TDD (Time Division duplex, chinese), there may be Time slots without data transmission during the communication process, so that diversity may be turned on in these Time slots, thereby determining the bit error rate at this Time as the second bit error rate on the basis of not affecting the current communication.
In step 102, it is determined whether a diversity-on condition is satisfied according to the communication status information and the diversity status information.
Wherein, according to the communication state information and the diversity state information, it can be determined whether to cause further deterioration of the reception sensitivity after the diversity is turned on based on the current communication state, and when it is determined that the diversity is turned on to cause further deterioration of the reception sensitivity or the current reception sensitivity cannot be improved, the diversity turn-on condition is not satisfied; otherwise, it may be determined that the diversity-on condition is satisfied, and step 103 is performed.
In step 103, when it is determined that the diversity-on condition is satisfied, diversity is turned on.
Exemplarily, when the diversity-on condition is not satisfied, the main set communication is maintained, and diversity is not turned on; otherwise, diversity should be turned on, thereby improving the signal receiving performance and improving the communication quality of the terminal in the weak signal area.
In summary, in the communication method provided by the present disclosure, when the received signal strength of the primary set of the terminal is smaller than the preset signal strength threshold, the current communication state information and the state information of the diversity are acquired, and then it is determined whether the diversity-opening condition is satisfied according to the communication state information and the state information of the diversity, and when it is determined that the diversity-opening condition is satisfied, the diversity is opened. Therefore, the technical scheme provided by the disclosure can determine whether to adopt a diversity-opening communication mode according to the current communication state and the diversity state, and can improve the receiving performance of the terminal.
Fig. 2 is a flowchart illustrating another communication method according to an exemplary embodiment, where as shown in fig. 2, when the communication status information is a currently occupied channel, and the diversity status information includes a pre-recorded channel set where there is a reception sensitivity degradation condition for diversity, the determining, according to the communication status information and the diversity status information of the terminal, whether a diversity on condition is satisfied includes the following steps:
in step 1021, it is determined whether there is a channel in the set of channels that matches the currently occupied channel.
For example, in the development stage, a channel with diversity present may be determined through multiple experimental tests, so as to obtain the channel set, and information of the channel set is stored in the terminal.
When it is determined that the received signal strength of the primary set is degraded, the stored set of channels is obtained from the terminal, so as to determine whether the currently occupied channel matches with a channel in the set of channels in combination with the currently occupied channel determined in step 101.
That is to say, when there is a match between the currently occupied channel and the channel in the channel set, the diversity is turned on, which may result in a result of communication state degradation, and the performance of the diversity is not as good as that of the original communication method using only the main set path, so that it may be determined whether the diversity-on condition is satisfied by determining whether there is a matched channel in the channel set.
In step 1022, when there is a matching channel in the channel set, it is determined that the diversity on condition is not satisfied.
In step 1023, when there is no matching channel in the set of channels, it is determined that the diversity on condition is satisfied.
Fig. 3 is a flowchart illustrating another communication method according to an exemplary embodiment, where, as shown in fig. 3, a channel set includes channels with degraded receiving sensitivity corresponding to different application scenarios, and the determining whether there is a channel matching a currently occupied channel in the channel set in step 1021 includes:
in step 10211, a current first application scenario is determined.
The application scenario may be understood as a scenario when the terminal uses one (or several) functional modules (such as a camera, a speaker, and the like), and different application scenarios may be considered when the terminal uses different functional modules, and channels with reception sensitivity deterioration conditions may be different in different application scenarios. For example, when a non-communication module, such as a camera or a speaker, is turned on, a situation of degraded reception sensitivity may occur, and channels of degraded reception sensitivity when the camera or the speaker is turned on are different, so before determining whether a matching channel exists, the determination of the application scenario may be performed first.
In step 10212, a channel in the channel set corresponding to the first application scenario where there is a receive sensitivity degradation is acquired.
After the first application scenario is determined in step 10211, it is determined that there is a channel with degraded receiving sensitivity in the first application scenario, so as to determine whether the currently occupied channel is matched in step 10213 or step 10214.
In step 10213, when the currently occupied channel belongs to a channel corresponding to the first application scenario where there is a reception sensitivity deterioration condition, it is determined that there is a matching channel in the channel set.
In step 10214, when the currently occupied channel does not belong to a channel corresponding to the first application scenario where there is a reception sensitivity deterioration condition, it is determined that there is no matching channel in the channel set.
Or, in another implementation manner, fig. 4 is a flowchart illustrating another communication method according to an exemplary embodiment, and as shown in fig. 4, when the communication status information is the first error rate and the diversity status information is the second error rate, the determining, according to the communication status information and the diversity status information, whether the diversity-on condition is met in step 102 includes the following steps:
in step 1024, the first bit error rate is compared to the second bit error rate.
In step 1025, it is determined that the diversity on condition is satisfied when the second error rate is less than the first error rate.
In step 1026, it is determined that the diversity on condition is not satisfied when the second error rate is greater than or equal to the first error rate.
Illustratively, the first error rate is an error rate of current communication, that is, an error rate when only the main set channel is enabled for communication, and the second error rate is an error rate when the diversity is enabled for current communication, so that the comparison between the first error rate and the second error rate is an error rate comparison in the case of not enabling the diversity and enabling the diversity.
When the second error rate is greater than or equal to the first error rate, the error rate of opening the diversity is greater than or equal to the error rate of not opening the diversity, namely after the diversity is opened, the performance of two paths is deteriorated or not improved, so the diversity is not opened, and the diversity opening condition is not satisfied; on the contrary, when the second error rate is less than or equal to the first error rate, it indicates that the error rate of turning on the diversity is less than the error rate of not turning on the diversity, that is, it indicates that the receiving performance of the current communication is improved after turning on the diversity, so that the diversity turning-on condition is satisfied, and the operation of step 103 may be continued.
In summary, in the communication method provided by the present disclosure, when the received signal strength of the primary set of the terminal is smaller than the preset signal strength threshold, the current communication state information and the state information of the diversity are acquired, and then it is determined whether the diversity-opening condition is satisfied according to the communication state information and the state information of the diversity, and when it is determined that the diversity-opening condition is satisfied, the diversity is opened. Therefore, the technical scheme provided by the disclosure can determine whether to adopt a diversity-opening communication mode according to the current communication state and the diversity state, and can improve the receiving performance of the terminal.
