Background
At present, with the development of communication technology, various communication devices have become indispensable devices for people's life. In the communication process of the communication device, in order to ensure the communication quality, reduce the influence of signal fading, and ensure the signal transmission quality, a diversity technique is usually adopted to transmit signals between a signal transmitting end and a signal receiving end. The diversity technique is to use multiple signal paths that transmit the same information and have approximately equal average signal strength and mutually independent fading characteristics, and appropriately combine these signals at the receiving end, so as to greatly reduce the influence of multipath fading, thereby improving the reliability of transmission. That is, if one wireless propagation path experiences deep fading, and another relatively independent path may still contain a strong signal, two or more signals may be selected from the multiple signals to be combined, so that the instantaneous signal-to-noise ratio and the average signal-to-noise ratio of the receiving end can be simultaneously improved, the influence of multipath fading is further reduced, and the reliability of information transmission is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The multi-antenna diversity transmitting method based on power consumption management aims to adopt a multi-antenna diversity transmitting signal to carry out dormancy through an adaptive selection diversity antenna on a signal transmitting end, so that the power consumption of the signal transmitting end is reduced while the signal transmitting performance is guaranteed, and the power consumption management of the signal transmitting end is optimized. Compared with the traditional signal transmitting terminal, when the multi-antenna is adopted for signal diversity transmission, in order to guarantee the signal transmission performance and improve the signal transmission quality, a multi-antenna diversity transmission technology is adopted, each diversity antenna is required to transmit signals of signal copies of the same information through transmitting frequencies with larger intervals, the signal copies are received through the signal receiving antennas which correspond to the signal receiving terminals, and a plurality of signal copies are selected from the signal receiving antennas to combine diversity signals, so that the signal transmission quality is guaranteed. Since a certain number of antennas are needed to transmit signals in diversity, the power consumption of the signal transmitting end is necessarily increased when the number of diversity antennas is increased. Therefore, the multi-antenna diversity transmission method based on power consumption management is provided in the embodiment of the application, so as to solve the problem of power consumption management of the existing signal transmitting terminal.
The first embodiment is as follows:
fig. 1 is a flowchart of a multi-antenna diversity transmitting method based on power consumption management according to an embodiment of the present invention, where the multi-antenna diversity transmitting method based on power consumption management provided in this embodiment may be executed by a multi-antenna diversity transmitting apparatus based on power consumption management, the multi-antenna diversity transmitting apparatus based on power consumption management may be implemented in a software and/or hardware manner, and the multi-antenna diversity transmitting apparatus based on power consumption management may be formed by two or more physical entities or may be formed by one physical entity. Generally, the multi-antenna diversity transmitting device based on power consumption management can be a signal transmitting end device such as a communication device, a gateway or a base station.
The following description will be made by taking a signal transmitting terminal as an example of a main body for performing a multi-antenna diversity transmission method based on power consumption management. Referring to fig. 1, the power management-based multi-antenna diversity transmission method specifically includes:
and S110, in a power consumption management period, the signal transmitting end transmits a plurality of signal copies corresponding to the same information to the testing end through a plurality of diversity antennas, and the testing ends are arranged corresponding to different spatial positions.
Exemplarily, referring to fig. 2, a schematic structural diagram of a corresponding signal transmitting end according to an embodiment of the present application is provided. The signal transmitting end is provided with N diversity antennas and corresponding transmitters, and each diversity antenna and corresponding transmitter are used for transmitting diversity signals through a corresponding signal branch (i.e. channel), namely, each signal copy corresponding to the same information. Each diversity antenna transmits diversity signals by using transmitting frequencies with large intervals, so that the diversity signals are independent from each other and do not interfere with each other. When the signal is transmitted, the processor provides information, and corresponding signal copies are generated based on the information and are transmitted through each transmitter and the corresponding antenna. Corresponding to one end of the signal receiving end, receiving each diversity signal through a plurality of corresponding signal receiving antennas, and combining the diversity signals, thereby realizing signal diversity transmission of the signal transmitting end and signal diversity reception and combination of the signal receiving end.
It can be understood that, for the same information, after each diversity antenna transmits a signal copy to the signal receiving end, when the signal receiving end performs diversity signal combining based on multiple signal copies, it is generally not necessary to combine all signal copies received by branches corresponding to all signal receiving antennas. But rather the diversity signal is combined from preferably several signal copies in each branch. In this way, for a branch that does not need to provide a signal copy for its part, the signal copy transmitted by its corresponding diversity antenna need not be used for the combination of the diversity signals. Therefore, in order to avoid the idle work of the antenna, reduce unnecessary energy consumption of the signal transmitting terminal, and optimize system energy consumption management, the embodiment of the application performs sleep through the adaptive selection diversity antenna to perform power consumption management of the signal transmitting terminal.
Specifically, in the embodiment of the present application, the power consumption management period is set, and the diversity antenna is selectively dormant in each power consumption management period. The power management period is set according to the actual power management requirement, such as 12 hours, 24 hours or even one week. When a power consumption management period begins, the signal transmitting terminal firstly transmits the signal copies of the same information through all the antennas respectively. Each diversity antenna transmits a corresponding signal copy through a different signal branch (i.e., channel). Based on the signal copies transmitted by each diversity antenna, the embodiment of the application sets the test end as a signal receiving end to receive each signal copy transmitted by each diversity antenna, and based on the received signal copies, the test end measures and calculates the initial signal quality parameters of the signal branches corresponding to each diversity antenna to preliminarily judge the signal transmission quality of each signal branch.
Further, referring to fig. 3, a schematic communication diagram of the signal sending end 11 and the test end 12 according to the embodiment of the present application is provided, as shown in fig. 3, there are a plurality of test ends. In the embodiment of the application, the signal copies transmitted by all the diversity antennas are respectively received by the plurality of test terminals, so that the signal transmission quality of the signal branch corresponding to each diversity antenna is tested by each test terminal. It can be understood that, in the embodiment of the application, by setting the plurality of test terminals to respectively and independently test the signal transmission quality of all the signal branches, the contingency of the test result can be avoided, so that the test result is more convincing. Optionally, the test terminal is correspondingly set at a plurality of different spatial positions selected within the signal coverage range of the corresponding signal transmitting terminal. For example, the test ends are arranged at different positions in the cell of the base station, and the signal transmission quality of the signal branch corresponding to each diversity antenna of the base station is tested through the test ends at different spatial positions, so that the test result of the test end can better meet the actual transmission condition of each signal branch, and the condition that the test result has certain contingency due to a single position and a single test end is avoided.
And S120, receiving initial signal quality parameters of signal transmitting branches corresponding to the diversity antennas fed back by the testing ends, wherein the initial signal quality parameters are determined according to the corresponding signal copies.
Correspondingly, after receiving the signal copies transmitted by all diversity antennas, each testing terminal calculates the initial signal quality parameters of the corresponding signal branch corresponding to each signal copy. The initial signal quality parameter represents the signal quality of the signal received by the current test end through each signal branch, and it can be understood that, if the signal quality of a signal received by a certain signal branch is relatively high, the signals correspondingly received by the signal branch are received and combined, so that the signal quality of the combined signal can be effectively guaranteed. Similarly, on the premise of ensuring the signal transmission performance, for the signal copies received by the other signal branches, if the relative signal quality deviation indicates that the signal copies transmitted by the signal branch are not adopted for diversity signal combination, the power consumption of the signal transmission end can be effectively reduced by sleeping the diversity antennas corresponding to the signal branch.
Further, in the embodiment of the present application, the initial signal quality parameter is determined based on the signal received power, the signal received strength, the instantaneous channel quality value, and/or the interference signal strength corresponding to the signal replica. Wherein the channel instantaneous quality value represents the channel quality, channel matrix feedback, signal response and/or interference information of the corresponding branch. The various types of parameters are measured by corresponding signal replicas and antenna parameters. Further, in order to quantize the initial signal quality parameter, a calculation formula of the initial signal quality parameter is provided to quantize the initial signal quality parameter, so as to compare the initial signal quality parameters corresponding to the diversity antennas. The calculation formula of the initial signal quality parameter is as follows:
f＝ω1P+ω2d1+ω3h+ω4d2
wherein f is an initial signal quality parameter, P is a signal receiving power, d1 is a signal receiving intensity, h is a channel instantaneous quality value, d2 is an interference signal intensity, ω 1, ω 2, ω 3, and ω 4 are corresponding influence factors respectively, and the influence factors are determined according to an actual test and can be set according to actual influences of various types of parameters on the signal quality parameter. Based on the initial signal quality parameter calculation formula, the signal quality parameters of the signal branches corresponding to the diversity antennas can be determined. It should be noted that, in practical application, according to different signal quality evaluation criteria, a plurality of different manners may be selected to evaluate the signal quality of the signal transmitted by each diversity antenna, and a corresponding quantization formula is set accordingly. The above formula is only one calculation method for calculating the initial signal quality parameter in the embodiment of the present application, and various different measurement and calculation formulas may be selected according to actual measurement and calculation requirements, which is not described herein again.
In addition, it should be noted that, in the practical application process, the signal transmission gain, the fading condition of the signal copies transmitted by each signal branch, and even the performance of the signal copies can also be used as the evaluation index of the initial signal quality parameter. Taking the performance of the signal copies as an example, by setting a plurality of detection tubes at the receiver corresponding to each signal receiving antenna at the test end, each detection tube correspondingly converts the signal copies received by the signal receiving antenna into diversity signals in a low frequency or direct current signal form, and further by determining the power of each diversity signal, the performance of each diversity signal is represented by the power of the signal. In the prior art, there are many ways to evaluate the signal quality of a wireless signal, and the embodiments of the present application are not limited herein.
Based on the above measuring and calculating process of the testing terminal, the signal quality corresponding to each signal copy, that is, the initial signal quality parameters of the signal branches corresponding to different diversity antennas at the signal transmitting terminal, can be determined. In one embodiment, to avoid the chance of single signal measurement at the test end, the diversity antenna may transmit multiple signal copies corresponding to different information sequentially while transmitting the signal copies. Correspondingly, the initial signal quality parameters of the signal copies transmitted by each diversity antenna are measured for multiple times through the test end to obtain a plurality of signal quality parameter values corresponding to one diversity antenna, wherein each signal quality parameter value is obtained by measuring and calculating according to the signal copy of one piece of information. Further based on a plurality of signal quality parameter values, the embodiment of the application obtains an initial signal quality parameter representing the signal quality of a branch corresponding to one diversity antenna by means of averaging.
Based on the measuring and calculating mode, finally, each testing end measures and calculates the initial signal quality parameters of the signal branches corresponding to the diversity antennas according to the received signal copies.
S130, determining the signal quality parameter mean value of the signal transmitting branch corresponding to each diversity antenna based on the initial signal quality parameter.
S140, screening the diversity antenna as a dormant antenna based on the signal quality parameter mean value, and controlling the dormant antenna to conduct periodic dormancy.
It can be understood that each initial signal quality parameter fed back by each testing end corresponds to each diversity antenna of the signal transmitting end. And because the setting positions of the test ends are different, the specific numerical values of the initial signal quality parameters which are measured and calculated by each test end and correspond to one diversity antenna are generally different. Therefore, for a diversity antenna, the corresponding initial signal quality parameters measured and calculated by each test end are averaged to obtain the signal quality parameter average value of the signal transmitting branch corresponding to the diversity antenna. The signal transmitting terminal represents the signal transmission quality of the signal branch corresponding to each diversity antenna by the signal quality parameter mean value, and the diversity antennas are screened and dormant by the signal quality parameter mean value.
Specifically, referring to fig. 4, the screening process of the dormant antenna includes:
s1401, arranging each diversity antenna in a descending order according to the signal quality parameter mean value to obtain a corresponding diversity antenna sequence;
s1402, screening a plurality of diversity antennas from the diversity antenna sequence to be used as dormant antennas based on a preset antenna quantity threshold and/or a signal quality parameter threshold.
And arranging the diversity antennas in a descending order through the signal quality parameter mean value to obtain a corresponding diversity antenna sequence. It will be appreciated that the antennas arranged at the front end of the diversity antenna sequence transmit signals of relatively good signal quality, whereas the antennas arranged at the rear end of the diversity antenna sequence transmit signals of relatively poor signal quality. Based on the determined diversity antenna sequence, through a preset antenna number threshold and/or signal qualityAnd screening the dormant antennas by using the quantity parameter threshold. The antenna number threshold is used for limiting the number of the antennas which are reserved for operation in screening, and the signal quality parameter threshold is used for limiting the signal quality parameter value of the antennas which are reserved for operation in screening. Specifically, the diversity antennas with the corresponding number are sequentially screened from the antenna sequence from large to small according to the threshold value of the number of the antennas; or screening the corresponding diversity antenna from the antenna sequence according to the signal parameter threshold; or screening the corresponding diversity antenna from the antenna sequence according to the signal parameter threshold, and screening the screened diversity antenna again according to the antenna number threshold. If the dormant antenna is screened by the antenna number threshold n alone, n diversity antennas are screened and reserved from the diversity antenna sequence according to the antenna number threshold n from large to small according to the signal quality parameter average value, and the rest diversity antennas are used as the dormant antenna. If the signal quality parameter threshold f is used alone0And screening the dormant antennas, reserving a part of antennas with the signal quality parameter mean value reaching the threshold value to continue to operate according to the signal quality parameter threshold value, and taking the rest diversity antennas as the dormant antennas. In order to better guarantee the signal transmission performance during screening of the dormant antennas, the dormant antennas can be screened by integrating the number threshold of the antennas and the signal quality parameter threshold. By thresholding a signal quality parameter f0The first screening of the antenna is carried out, and the mean value of the signal quality parameters is kept to reach the quality parameter threshold value f0The other antennas are dormant. Further, for partial diversity antennas which are kept to operate, whether the number of the antennas which are kept to operate currently exceeds the number threshold of the antennas is judged, if yes, the antennas which exceed the number threshold are screened out from small to large according to the signal quality parameter average value to serve as dormant antennas, and if not, current antenna screening is directly finished. The corresponding antenna with the relatively low signal quality parameter mean value is adaptively selected for dormancy, so that the unnecessary power consumption of the antenna is saved while the emission performance of the antenna is guaranteed, and the energy consumption management effect of the system is optimized.
In one embodiment, after the signal receiving end preliminarily determines the dormant antennas, the signal receiving end further verifies the screening of the dormant antennas based on the antenna combinations by receiving transmitting antenna combinations fed back by each testing end, and outputs corresponding verification results, where the transmitting antenna combinations include a plurality of diversity antennas, the testing end determines corresponding signal receiving antennas according to the signal copies screened during diversity signal combining, and determines corresponding diversity antennas based on the corresponding signal receiving antennas, so as to form the transmitting antenna combinations. It can be understood that, in order to ensure the signal quality of the combined signal, the test end selects the combined signal obtained by further combining the diversity signals, and generally the combined signal with the best signal quality, and determines the signal receiving antenna to which each signal copy belongs, corresponding to the signal copy of the combined signal. Furthermore, as the frequency diversity transmission and reception technology is adopted, each signal receiving antenna corresponds to the diversity antenna at the signal transmitting end one by one, and the corresponding diversity antenna can be determined according to the signal receiving antenna corresponding to the combined signal, and the transmitting antenna combination is formed by the diversity antennas. The signal copies transmitted by each diversity antenna in the diversity antenna combination can obtain combined signals with relatively high quality after the signals are combined by the test terminal. Specifically, the signal quality of the combined signal may be determined according to the attenuation condition, waveform, and other characteristics of the combined signal, and there are many ways to quantize the signal quality of the diversity combined signal in the prior art, which are not described herein again.
Further, based on the above characteristics, the dormant antennas are screened and verified by receiving the transmitting antenna combinations fed back by each test end, and it can be understood that the signal quality of the signal copies transmitted to the corresponding test end by each diversity antenna in the transmitting antenna combinations is relatively good. And counting the occurrence times of each diversity antenna in each transmitting antenna set, if the occurrence times of a certain diversity antenna reaches a set time threshold value and is set as a dormant antenna during the screening of the dormant antenna, verifying that the dormant antenna is unreasonably screened, and outputting a corresponding verification result. On the contrary, if the occurrence frequency of a certain diversity antenna is lower than the set frequency threshold value and the dormant antenna is set as the dormant antenna during screening of the previous dormant antenna, the screening of the dormant antenna is verified to be reasonable, and a corresponding verification result is output.
Furthermore, the screening of the dormant antenna is modified according to the verification result, and the corresponding dormant antenna is awakened again and/or the corresponding diversity antenna is dormant. It can be understood that, if it is not reasonable to verify the screening of the dormant antennas, the antennas need to be reselected to sleep according to the verification result, and the corresponding diversity antennas that are erroneously dormant need to be awakened again. Through the verification of screening the dormant antenna, the accuracy of screening the dormant antenna can be ensured, and the antenna emission performance of the system can be guaranteed.
In addition, in an embodiment, after a signal transmitting end sleeps a part of the antennas, a sleep signal is further transmitted to each of the test ends, where the sleep signal is used to control a signal receiving antenna corresponding to the test end to sleep. It can be understood that the signal receiving antennas arranged at the test end correspond to the diversity antennas at the signal transmitting end one by one. When a certain diversity antenna of the signal transmitting terminal is dormant, in order to reduce the power consumption of the testing terminal and avoid part of the antennas from doing useless work, the corresponding signal receiving antenna of the testing terminal is controlled to be dormant through the dormant signal, so that the power consumption of the testing terminal can be saved, and the power consumption management of the testing terminal is optimized.
S150, when the current power consumption management period is finished, the dormant antenna is awakened again, and the next power consumption management period is carried out.
Finally, after screening the dormant antennas, for the current power consumption management period, the dormant state of each dormant antenna is kept until the current power consumption management period is finished. Referring to fig. 5, diversity antennas are arranged based on a signal quality parameter mean value by calculating the signal quality parameter mean value of each diversity antenna during a power consumption management period, and then a signal quality parameter threshold value f is set according to an antenna number threshold value n0Screening the antennas, and determining the final dormant antenna by combining screening verification of the dormant antenna. And when one power consumption management period is finished, the dormant antenna is awakened again, and the next power consumption management period is carried out, so that the processing flow of one power consumption management period is completed.

Therefore, the embodiment of the application can optimize the operation and maintenance effect of the system and further ensure the transmitting performance of the signal transmitting end by determining that the antenna is the abnormal antenna and outputting the abnormal prompt of the abnormal antenna.

By adopting the technical means, the antenna dormancy can be adaptively selected, and the power consumption of the signal transmitting end is reduced while the signal transmitting performance is guaranteed. In addition, by determining the abnormal antenna and performing the abnormal prompt, the embodiment of the application can further ensure the transmitting performance of the signal transmitting terminal and optimize the operation and maintenance effect of the signal transmitting terminal.
