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 application provides a power consumption management method for multi-antenna diversity reception, which aims to screen antennas at a signal receiving end adopting a multi-antenna diversity reception signal mode and correspondingly dormant antennas screened by dormancy, so that the power consumption of the signal receiving end is saved while the signal receiving performance is ensured. Compared with the traditional signal receiving end, in order to guarantee the signal receiving performance, reduce the influence of signal fading and improve the signal quality, the signal receiving end adopts a multi-antenna diversity receiving mode to receive signals, and further obtains signals with relatively high quality by combining various diversity signals so as to guarantee the signal receiving performance. Because the multi-antenna diversity technology is adopted for signal receiving, a plurality of antennas are required to run in real time to receive each signal copy corresponding to the same information. In addition, in order to ensure high quality of signals and reduce the influence of signal fading, a certain number of signal branches are required to receive signals, so as to ensure that the finally combined signals meet the corresponding quality requirements. Because a certain number of antennas need to be ensured to receive diversity signals, the more the number of antennas is opened, the larger the power consumption of the signal receiving end is. Therefore, the power consumption management method for multi-antenna diversity reception in the embodiment of the present application is provided to solve the problem of power consumption management of the existing signal receiving end.
The first embodiment is as follows:
fig. 1 is a flowchart of a power consumption management method for multi-antenna diversity reception according to an embodiment of the present disclosure, where the power consumption management method for multi-antenna diversity reception provided in this embodiment may be executed by a power consumption management device for multi-antenna diversity reception, the power consumption management device for multi-antenna diversity reception may be implemented in a software and/or hardware manner, and the power consumption management device for multi-antenna diversity reception may be formed by two or more physical entities or may be formed by one physical entity. In general, the power consumption management device for multi-antenna diversity reception may be a signal receiving device, a base station, a gateway, or other communication devices.
The following description will be made taking the power consumption management apparatus for multi-antenna diversity reception as an example of a main body of a power consumption management method for performing multi-antenna diversity reception. Referring to fig. 1, the power consumption management method for multi-antenna diversity reception specifically includes:
s110, in a power consumption management period, receiving a plurality of signal copies corresponding to the same information based on a plurality of antennas, and determining signal quality parameters of signal receiving branches corresponding to the antennas based on the signal copies.
Exemplarily, referring to fig. 2, a schematic structural diagram of a signal receiving end of a power consumption management device corresponding to multi-antenna diversity reception according to an embodiment of the present application is provided. The signal receiving end is provided with N antennas and corresponding receivers, and each antenna and corresponding receiver are used for receiving diversity signals of a corresponding signal branch (i.e. channel). The diversity signals are transmitted to a processor, which is generally a baseband processor, through respective receivers, and the processor processes the respective diversity signals and combines the diversity signals, thereby implementing signal diversity reception and combining at a signal receiving end. It can be understood that, for the signal copies received by each antenna of the same information, when performing diversity signal combining, it is generally not necessary to combine all the signal copies received by the branches corresponding to all the antennas. But rather the 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 received by its corresponding antenna need not be used for diversity signal combining. Therefore, in order to avoid the idle work of the antenna, reduce unnecessary energy consumption of the signal receiving end, and optimize system energy consumption management, the embodiment of the application performs sleep through adaptively selecting the antenna to perform power consumption management of the signal receiving end.
Specifically, in the embodiment of the present application, by setting the power consumption management period, the selective sleep of the antenna is performed 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, a signal receiving end receives signal copies of the same information through all antennas, and each antenna receives corresponding signal copies through different signal branches (i.e., channels). Based on the signal replicas received by the antennas. And measuring and calculating the signal quality parameters. The signal quality parameters represent the signal quality of signals received by branches corresponding to the antennas at present, and it can be understood that, if the signal quality parameter of a branch receiving a signal is relatively high, the signal is received and combined by the antenna corresponding to the branch, so that the signal receiving performance and the quality of the combined signal can be effectively guaranteed. Under the premise of ensuring the signal receiving performance, the power consumption of the system can be effectively reduced by sleeping the antenna corresponding to the antenna with relatively low signal quality parameters.
Further, in the embodiment of the present application, the signal quality parameter is determined based on the corresponding signal received power, signal received strength, channel instantaneous quality value and/or interference signal strength. 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. Furthermore, in order to quantize the signal quality parameter, a calculation formula of the signal quality parameter is provided to quantize the signal quality parameter, so as to compare the signal quality parameters corresponding to the antennas. The calculation formula of the signal quality parameter is as follows:
f＝ω1P+ω2d1+ω3h+ω4d2
wherein f is a signal quality parameter, P is a signal receiving power, d1For signal received strength, h is the instantaneous quality value of the channel, d2For interfering signal strength, omega1，ω2，ω3And ω4The influence factors are determined according to actual tests and can be set according to actual influences of various types of parameters on signal quality parameters. Based on the signal quality parameter calculation formula, the signal quality parameters of the branches corresponding to the antennas can be determined. It should be noted that, in practical applications, according to different signal quality evaluation criteria, a plurality of different manners may be selected to evaluate the signal quality of the signal received by each antenna, and a corresponding quantization formula is set accordingly. As described aboveThe formula is only one calculation method for calculating the signal quality parameter in the embodiment of the present application, and various different measurement and calculation formulas can 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 receiving gain, the fading condition of each branch signal copy, and even the performance of the signal copy may also be used as the evaluation index of the signal quality parameter. Taking the performance of the signal copies as an example, as shown in fig. 2, a multi-channel detector (not shown) is disposed at the receiver corresponding to each antenna, each channel detector converts the signal copies received by the antennas into diversity signals in the form of low-frequency or direct-current signals, and further characterizes the performance of each diversity signal by determining the power of each diversity signal and 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.
In one embodiment, in order to avoid the contingency caused by single signal measurement, the embodiment of the present application obtains a plurality of signal quality parameter values corresponding to one antenna by measuring the signal quality parameters of the received signal copies of each antenna for a plurality of times, wherein each signal quality parameter value is obtained by measuring and calculating according to different signal copies of the same information. Further based on a plurality of signal quality parameter values, the signal quality parameter mean value representing the signal quality of the corresponding branch of each antenna is obtained by means of averaging. And further taking the signal quality parameter mean value as the standard of antenna screening.
S120, arranging the antennas in a descending order according to the signal quality parameters corresponding to the antennas to obtain corresponding antenna sequences, screening the antennas from the antenna sequences to serve as dormant antennas based on a set antenna quantity threshold and/or a signal quality parameter threshold, and controlling the dormant antennas to conduct periodic dormancy.
After the signal quality parameters of the signal receiving branches corresponding to the antennas are determined, screening of the dormant antennas can be correspondingly performed. Specifically, when the antennas are arranged in a descending order according to the signal quality parameters corresponding to the antennas, if the signal quality parameter corresponding to one antenna is one, the antennas are directly arranged in a descending order according to the size of the signal quality parameter; and if the signal quality parameters corresponding to one antenna are multiple, calculating a signal quality parameter mean value of the antenna corresponding to the multiple signal quality parameters, and sorting the antennas in a descending order according to the size of the signal quality parameter mean value. And arranging the antennas in a descending order according to the signal quality parameter mean value obtained by one signal quality parameter or a plurality of signal quality parameters to obtain the corresponding antenna sequence. It will be appreciated that the antennas arranged at the front end of the antenna sequence receive signals of relatively good signal quality, while the antennas arranged at the rear end of the antenna sequence receive signals of relatively poor signal quality.
And based on the determined antenna sequence, screening the antennas through a preset antenna quantity threshold and/or a signal quality 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 antennas with the corresponding number are sequentially screened from large to small in the antenna sequence according to the antenna number threshold; or, screening the corresponding antenna from the antenna sequence according to the signal parameter threshold; or screening the corresponding antennas from the antenna sequence according to the signal parameter threshold, and re-screening the screened antennas according to the antenna quantity threshold. If the dormant antenna is screened by the antenna number threshold n alone, n antennas are screened and reserved from the antenna sequence according to the antenna number threshold n from large to small according to the signal quality parameter value, and the rest antennas are used as the dormant antenna. If the signal quality parameter threshold f is used alone0And screening the dormant antennas, reserving part of the antennas with the signal quality parameters reaching the threshold value to continue to operate according to the signal quality parameter threshold value, and taking the rest antennas as the dormant antennas. In order to better guarantee the signal receiving 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 mixing signal qualitiesQuantity parameter threshold f0The first screening of the antennas is carried out, keeping the signal quality parameter to reach the quality parameter threshold f0The other antennas are dormant. Further, for part of the antennas which are kept in operation, whether the number of the antennas which are kept in operation 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 parameters to serve as dormant antennas, and if not, the current antenna screening is directly finished. The corresponding antenna with relatively low signal quality parameters is adaptively selected to be dormant, so that the receiving performance of the antenna is guaranteed, and unnecessary power consumption of the antenna is saved, thereby optimizing the energy consumption management effect of the system.
In an embodiment, in order to ensure the reasonableness of screening of the dormant antennas, the power consumption management device for multi-antenna diversity reception according to the embodiment of the present application further verifies the screening of the dormant antennas. Referring to fig. 3, the dormant antenna screening verification process includes:
s121, randomly selecting a plurality of antennas to form an antenna combination, and combining the signals of the corresponding signal copies based on the antenna combination to generate corresponding combined signals.
S122, the screening of the dormant antennas is verified according to the combined signals correspondingly generated by the antenna combinations, and corresponding verification results are obtained.
Specifically, in the embodiment of the present application, an antenna combination is formed by randomly selecting antennas, and diversity signals are combined for signal copies previously received by each antenna in the antenna combination, so as to obtain corresponding combined signals. With reference to the above manner, antennas are randomly selected to form antenna combinations by a set number of times, and combined signals are determined by combining signal replicas, so that combined signals corresponding to the antenna combinations are obtained. The number of randomly selected antennas may be equal to the number of antennas that remain in operation during the dormant antenna screening process.
Further, based on the above-determined respective combined signals, which are defined as first combined signals, the signal quality of the respective first combined signals is determined. The quantization method of the signal quality may be determined by referring to the quantization method of the signal quality parameter in step S110, or may be determined by the characteristics of the attenuation condition, waveform, and the like of the combined signal. Correspondingly, based on the antennas which are kept running in the dormant antenna screening process, the combined signal of the signal copies received by each antenna before the diversity combination is determined, the combined signal is defined as a second combined signal, and the signal quality of the second combined signal is quantized.
Furthermore, by comparing the signal quality of the first combined signal and the signal quality of the second combined signal one by one, if the signal quality of the second combined signal is higher than the signal quality of the first combined signal, or the signal quality in the first combined signal is higher than the signal quality of the second combined signal and is less than a set signal quantity threshold, the screening of the previous dormant antenna is verified to be reasonable, and a corresponding verification result is output. On the contrary, if the number of the first combined signals is higher than the number of the second combined signals and reaches the set number threshold, the screening of the dormant antenna before is unreasonable, and a corresponding verification result is output. It will be appreciated that the first combined signal is obtained by diversity combining the signal copies of each antenna in a randomly selected antenna combination, which typically includes the antenna that is remaining operational and the antenna that is selected to be dormant. If the signal quality of the first combined signal corresponding to the antenna combination is better than the signal quality of the second combined signal, it indicates that the signal reception performance of each antenna that is being kept in operation may not be as good as the signal reception performance of the antenna combination. When the signal quality of a plurality of second combined signals (namely the set signal quantity threshold value is reached) is superior to that of the first combined signal, the receiving performance of a plurality of other antenna combinations is superior to that of the antenna combination which is kept running at the moment, namely, the screening of the dormant antenna is not reasonable, the screening of the previous dormant antenna is verified to be not 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 dormant. Generally, if the screening of the dormant antenna is verified to be reasonable, the dormant antenna is not modified. And if the verification result is not reasonable, modifying the dormant antenna. When the dormant antenna is modified, according to the corresponding antenna combination of the first combined signal, the signal quality of which is superior to that of the second combined signal, the antennas are re-screened from the corresponding number from large to small according to the occurrence frequency of each antenna to keep running, and the dormant antenna is modified based on the screened antennas.
S130, 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. 4, during a power management period, antennas are arranged by an antenna signal quality parameter f, and then according to an antenna number threshold n and a signal quality parameter threshold f0Screening 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.
In addition, in an embodiment, the power consumption management device for multi-antenna diversity reception counts antennas that are dormant in each power consumption management period, and determines, if the corresponding antennas are continuously screened as the dormant antennas in a set number of power consumption management periods based on the statistical result of the dormant antennas, the corresponding antennas as abnormal antennas, and outputs an abnormal prompt of the abnormal antennas. It can be understood that, if a certain antenna is continuously screened as a dormant antenna within a set number of power consumption management periods, a signal received by a signal branch corresponding to the antenna generally has a poor signal quality, and in order to solve the problem, a relevant operation and maintenance person needs to be prompted in time to replace the antenna or modify a relevant parameter of the antenna, so as to improve a situation that a signal attenuation of the corresponding signal branch is severe. Therefore, the embodiment of the application can optimize the operation and maintenance effect of the system and further ensure the receiving performance of the signal receiving end by determining that the antenna is the abnormal antenna and outputting the abnormal prompt of the abnormal antenna.
The signal quality parameters of the signal receiving branches corresponding to the antennas are determined in one power consumption management period, the antennas are arranged in a descending order according to the signal quality parameters corresponding to the antennas to obtain corresponding antenna sequences, the antennas are screened from the antenna sequences to be used as dormant antennas based on the set antenna quantity threshold and/or signal quality parameter threshold, the dormant antennas are controlled to conduct periodic dormancy, and when the current power consumption management period is finished, the dormant antennas are awakened again to conduct the next power consumption management period. By adopting the technical means, the antenna can be adaptively selected to sleep, the power consumption of the signal receiving end is reduced while the receiving performance of the signal receiving end is guaranteed, and better energy consumption management of the signal receiving end is realized.
In addition, according to the embodiment of the application, the abnormal antenna is determined and the abnormal prompt is carried out, so that the receiving performance of the signal receiving end can be further guaranteed, and the operation and maintenance effect of the signal receiving end is optimized.
