Detailed Description
In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the attached drawings, the described embodiments should not be considered as limiting the present application, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
In the following description, references to the terms "first \ second \ third" are only to distinguish similar objects and do not denote a particular order, but rather the terms "first \ second \ third" are used to interchange specific orders or sequences, where appropriate, so as to enable the embodiments of the application described herein to be practiced in other than the order shown or described herein.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.
Before further detailed description of the embodiments of the present disclosure, terms and expressions referred to in the embodiments of the present disclosure are explained, and the terms and expressions referred to in the embodiments of the present disclosure are applied to the following explanations.
1) Received Signal Strength Indicator (RSSI): in practice not a linear evaluation criterion like voltage or temperature but a ratio between the current signal and some initial "standard" value, in particular the wideband received power over the channel bandwidth received by the receiver, in dB (and in sound level), is a logarithmic criterion and not linear.
2) Antenna transmission power: the transmission power of a radio wave refers to energy in a given frequency band.
3) Antenna gain: refers to the ratio of the radiation power flux density of the antenna in a given direction to the radiation power density of a reference antenna (usually an ideal point source). Quantitatively describing the degree to which an antenna radiates input power collectively, antenna gain, in short, refers to the ability of an antenna to transmit and receive signals in a particular direction.
4) Antenna radiation performance: the total energy transmitted by an antenna is measured as the total energy transmitted by the antenna, namely the transmission power of the antenna + the gain of the antenna, because the energy of electromagnetic waves in a wireless system is generated by the superposition of the transmission energy of a transmitting device and the amplification of the antenna.
5) Specific Absorption Rate (Specific Absorption Rate SAR): meaning an electromagnetic wave absorption ratio or ratio, is the electromagnetic wave energy absorption ratio of a mobile phone or wireless product, which is positioned such that an electromagnetic field will be induced in a human body under the action of an external electromagnetic field. It will be appreciated that since various organs of the human body are lossy media, electromagnetic fields in the body will generate currents that result in the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. SAR means the electromagnetic power absorbed or consumed by a unit mass of human tissue, in W/kg. It is common in the related art to configure and store a Specific Absorption Rate (SAR) table for a mobile broadband modem in a registry of a device.
6) MIMO: the technology is a technology which uses a plurality of transmitting antennas and receiving antennas at a transmitting end and a receiving end respectively, can improve the capacity and the spectrum utilization rate of a communication system by times under the condition of not increasing the bandwidth, and has been applied to WiFi to a certain extent at present.
At present, uplink MIMO generally uses two antennas for data transmission, and in order to effectively avoid error code retransmission of data and achieve the best throughput, it is necessary to ensure that the radiation performance of the two antennas is consistent as much as possible.
However, in the actual use process, although the transmission power of the antennas is basically the same, in the actual use process, the radiation performance of the antennas is often different due to different antenna gains caused by different antenna positions, and in the actual use process of a user, the radiation performance of the two antennas also deviates due to factors such as the placement position of a mobile phone or wireless equipment or the shielding of hands, and the like, thereby further causing the defect of reduced data transmission performance.
Exemplarily, fig. 1 is a schematic diagram of a scene affecting antenna radiation performance, as shown in fig. 1, a device 100 configures a first antenna ANT1 and a second antenna ANT2, as shown in fig. 1, corresponding positions of the two antennas are different, and a situation that a human hand is blocked by the antenna ANT2 exists.
In view of the above, how to adjust the uniformity of the antenna radiation performance is the content discussed in the embodiments of the present application, the following description will be made with reference to the following specific embodiments.
The embodiment of the application provides a power adjusting method, which comprises the steps of determining an RSSI difference value between a first antenna and a second antenna; determining an adjustable transmission power difference parameter between the first antenna and the second antenna based on the RSSI difference value; and then adjusting the first current transmitting power corresponding to the first antenna and/or the second current transmitting power corresponding to the second antenna according to the adjustable transmitting power difference parameter. Therefore, the transmitting power between the two antennas can be dynamically adjusted through the RSSI difference value between the two antennas, and then the deviation of the radiation performance between the antennas caused by the difference of the antenna positions, the difference of gains and the shielding of hands is balanced, so that the radiation performance of the two antennas is consistent, and the data transmission performance is further improved.
The power adjusting method provided by the embodiment of the application is applied to power adjusting equipment. The following describes an exemplary application of the power adjustment device provided in the embodiment of the present application, and the power adjustment device provided in the embodiment of the present application may be implemented as a mobile phone, a notebook computer, a tablet computer, a desktop computer, a smart television, an in-vehicle device, a wearable device, a router, an industrial device, and the like, where the power adjustment device is configured with multiple radio frequency antennas and supports MIMO technology.
In the following, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides a power adjustment method, fig. 2 is a schematic implementation flow diagram of the power adjustment method provided in the embodiment of the present application, and as shown in fig. 2, in the embodiment of the present application, a method for performing power adjustment may include the following steps:
s101, determining an RSSI difference value between the first antenna and the second antenna.
It can be understood that the radiation performance of the antennas is related to the RSSI values, so that when the positions of the antennas and the radiation performance of the multiple antennas of the device are inconsistent due to the shielding, the inconsistency of the radiation performance among the antennas can be reflected by the inconsistency of the RSSI values among the antennas. Therefore, in the embodiment of the present invention, in order to reflect the current difference of the radiation performance of different antennas, the power adjustment device may first determine the RSSI difference between different antennas.
It should be noted that, in the embodiments of the present application, two antennas are taken as an example to perform an exemplary description of the power adjustment method.
Specifically, the power adjusting device can capture the RSSI values corresponding to the two antenna paths in real time during MIMO operation, including a first RSSI value corresponding to the first antenna and a second RSSI value corresponding to the second antenna, and then perform difference operation to determine the RSSI difference between the two antennas.
It should be appreciated that there may be a difference in RSSI values between the first and second antennas when either of the MIMO antennas is occluded by a human hand or by the presence of an obstruction. For example, as shown in fig. 3, a first antenna ANT1 and a second antenna ANT2 of the electronic device correspond to a first RSSI value and a second RSSI value, respectively, and when the second antenna is blocked by a human hand, a difference exists between the first RSSI value and the second RSSI value.
And S102, determining an adjustable transmission power difference parameter between the first antenna and the second antenna based on the RSSI difference value.
In the embodiment of the present invention, after the RSSI difference between the two antennas is determined, the difference of the radiation performance between the two antennas can be reflected based on the RSSI difference, and at this time, the adjustment of the antenna performance difference needs to be further performed to achieve the consistency of the radiation performance of the two antennas.
Specifically, the adjustable transmit power difference parameter between the antennas may be determined based on the RSSI difference value.
It should be understood that the total antenna transmission energy is antenna transmission power + antenna gain, that is, the two days determining the antenna radiation performance include the antenna transmission power and the antenna gain; in general, the transmission power of the different antennas of the mioo is autonomously controlled by the device, is a fixed quantity, and can be controlled to be consistent with the transmission power, so that the key factor causing the inconsistency of the antenna radiation performance is the antenna gain, that is, the difference of the RSSI values between the two antennas essentially reflects the difference of the antenna gains between the two antennas.
Due to the fact that the antenna position, the equipment position, the shielding of the human hand and the like can cause the difference of the antenna gain, and due to the fact that the situations such as how the equipment is placed and how the human hand touches the equipment cannot be determined, the adjustment of the difference of the antenna gain between the two antennas cannot be accurately achieved.
Therefore, in the embodiment of the present invention, the transmission powers of the two antennas can be adjusted, that is, the antenna powers become a variable, so that the difference between the adjusted transmission powers of the antennas can offset the difference between the antenna gains of the antennas, thereby making up for the case that the radiation performances brought by the antenna gains are inconsistent, and making the radiation performance corresponding to the first antenna consistent with the radiation performance corresponding to the second antenna.
In view of that the difference in gain between the antennas can be substantially reflected by the determined RSSI difference between the first antenna and the second antenna, if it is to be ensured that the radiation performance of the first antenna is consistent with that of the second antenna under the condition that the antenna gain difference cannot be accurately adjusted by corresponding means, the difference in transmission power between the first antenna and the second antenna can be further determined based on the RSSI difference between the antennas, and the difference in transmission power and the difference in antenna gain are used for canceling out each other.
Specifically, a difference parameter of the transmission power between the antennas may be determined based on the RSSI difference between the antennas, and the transmission power difference parameter may represent the transmission power difference between the antennas.
In one embodiment, the transmission power difference parameter may be in the same measurement unit as the RSSI difference and in a different measurement unit from the antenna transmission power difference; if the unit of the RSSI value is db, the unit of the antenna transmission power is mW, and the unit of the RSSI difference value is different from the unit of the antenna transmission power difference value, the antenna transmission power difference value parameter with the same unit of measurement can be determined based on the RSSI difference value, and then the conversion between the unit of measurement db and the unit of mW is carried out, so that the antenna transmission power difference value with the unit of mW is obtained.
In another embodiment, the measurement unit of the antenna transmission power can also be characterized by directly using the measurement unit dB after conversion of the units mW and dB, that is, the unit of the transmission power can be directly expressed by dB, and then the antenna transmission power difference parameter can be directly equivalent to the antenna transmission power difference.
For example, in the case that the measurement unit of the antenna transmission power is dB, assuming that the first antenna transmission power is TX power1, the second antenna transmission power is TX power2, the first antenna RSSI1, and the second antenna RSSI2, in the embodiment of the present invention, in order to ensure that the radiation performance of the first antenna and the second antenna is the same, the TX power2-TX power1 may be made equal to RSSI2-RSSI1, that is, the power difference is made equal to the RSSI difference.
S103, adjusting a first current transmitting power corresponding to the first antenna and/or a second current transmitting power corresponding to the second antenna according to the adjustable transmitting power difference parameter.
In the embodiment of the present invention, after determining the adjustable transmission power difference parameter between the first antenna and the second antenna based on the RSSI difference, the antenna transmission power difference needs to be further adjusted based on the difference parameter.
Specifically, the adjustable transmit power difference between the two antennas may be determined based on the adjustable transmit power difference parameter, and then the transmit power of at least one of the two antennas may be adjusted based on the difference.
In some embodiments, the transmission power of the first antenna may be fixed and not changed, and the transmission power difference between the first antenna and the second antenna is adjusted by adjusting the transmission power of the second antenna, so as to further offset the difference value caused by the antenna gain between the antennas, so that the radiation performance of the two antennas is consistent.
In other embodiments, the transmission power of the second antenna may be fixed and not changed, and the transmission power difference between the first antenna and the second antenna is adjusted by adjusting the transmission power of the first antenna, so as to further cancel the difference value caused by the antenna gain between the antennas, and make the radiation performance of the two antennas consistent.
In some embodiments, the transmission power of the first antenna and the transmission power of the second antenna may be changed simultaneously, and the difference between the transmission power of the first antenna and the transmission power of the second antenna is adjusted by adjusting the transmission power of the first antenna and the transmission power of the second antenna, so as to further cancel a difference value caused by antenna gain between the antennas, and make the radiation performance of the two antennas consistent.
The embodiment of the application provides a power adjusting method, which comprises the steps of determining an RSSI difference value between a first antenna and a second antenna; determining an adjustable transmission power difference parameter between the first antenna and the second antenna based on the RSSI difference value; and then adjusting the first current transmitting power corresponding to the first antenna and/or the second current transmitting power corresponding to the second antenna according to the adjustable transmitting power difference parameter. Therefore, the transmitting power between the two antennas can be dynamically adjusted through the RSSI difference value between the two antennas, and then the deviation of the radiation performance between the antennas caused by the difference of the antenna positions, the difference of gains and the shielding of hands is balanced, so that the radiation performance of the two antennas is consistent, and the data transmission performance is further improved.
Based on the above embodiments, in an embodiment of the present application, the method for performing power adjustment may further include the following steps:
s104, configuring a corresponding relation between a transmission power difference parameter and a transmission power group in a vacant group of an electromagnetic wave absorption ratio SAR configuration group; wherein, one transmitting power difference parameter corresponds to one transmitting power group; one transmit power group includes a first transmit power and a second transmit power.
In the embodiment of the present invention, the corresponding relationship between the transmission power difference parameter and the transmission power group may be configured in advance; each transmitting power difference parameter corresponds to a transmitting power group, one transmitting power group comprises a first transmitting power and a second transmitting power, and at least one of the first antenna transmitting power and the second transmitting power is different between the transmitting power groups.
In some embodiments, the SAR configuration set may be multiplexed, and the preset correspondence between the transmission power difference parameter and the transmission power set may be stored in the SAR configuration set.
It should be understood that, in the related art, a Specific Absorption Rate (SAR) table, that is, a SAR configuration set, is often configured and stored in a registry of a handset or a wireless device for configuring SAR powers in different states, where the SAR configuration set has a part of a null set, and we may multiplex the part of the null set, and configure a preset corresponding relationship between a transmission power difference parameter and a transmission power set in the null set in the SAR configuration set.
For example, a certain platform at high altitude contains up to 36 sets of SAR configurations, which can realize SAR power configurations in 18 different states, and generally only 1-3 sets of the SAR configurations are needed to complete normal SAR functions, and the rest 15 sets are vacant, so that the 15 vacant sets can be multiplexed, and the corresponding relationship between the preset transmission power difference parameter and the transmission power set is configured in the SAR vacant set.
Even if the configuration set of SAR is all empty, especially since no SAR testing is needed in the PRC project, we can multiplex all SAR configuration sets.
In other embodiments, the power adjustment device, such as a mobile phone or a wireless device, may also open a new configuration group in its own registry to store the corresponding configuration of the preset transmission power difference parameter and the transmission power group, which is not specifically limited in this application.
Specifically, based on the foregoing embodiment, fig. 4 is a second example of an implementation flow of the power adjustment method provided in the embodiment of the present invention, and as shown in fig. 4, the method for configuring the corresponding relationship between the transmission power difference parameter and the transmission power group in the idle group of the SAR configuration group includes the following steps:
s104a, determining the maximum transmitting power and the minimum transmitting power according to the current device type, and calculating the initial power difference value between the maximum transmitting power and the minimum transmitting power.
And S104b, determining a stepping value of the transmission power difference parameter based on the initial power difference value and the number of the idle groups.
S104c, constructing the corresponding relation between the transmission power difference parameter and the transmission power group based on the maximum transmission power, the minimum transmission power and the step value of the transmission power difference parameter.
S104d, configuring the corresponding relation between the transmission power difference parameter and the transmission power group in a vacant group; wherein, each idle group is configured with a corresponding relation between a transmitting power difference parameter and a transmitting power group.
In the embodiment of the present invention, when the multiplexing SAR idle set performs configuration of a corresponding relationship between a plurality of sets of transmission power difference parameters and a transmission power set, the corresponding relationship may be configured based on a plurality of preset configuration strategies.
In an embodiment, the configuration of the corresponding relationship may be performed by using a preset configuration policy that all the SAR idle groups are multiplexed.
Specifically, the current device type may be determined first, the corresponding maximum transmission power and the minimum transmission power may be determined based on the device type, and a difference between the maximum transmission power and the minimum transmission power, that is, an initial power difference, is calculated.
It can be understood that, if all the SAR null sets are to be multiplexed, that is, each null set is configured with a transmission power set corresponding to a transmission power difference of a certain size, at this time, the number of the SAR null sets is determined, then the maximum transmission power difference parameter corresponding to the maximum transmission power difference is determined based on the conversion of the measurement unit, and further the step value of the transmission power difference, in other words, the density of the transmission power difference parameter is determined based on the maximum transmission power difference parameter and the number of the SAR null sets. Here, the larger the maximum transmission power difference parameter is, the fewer null groups are, the larger the corresponding step value is, whereas the more null groups are, the smaller the corresponding step value is.
Further, the minimum transmit power difference parameter may be used as a starting point, and a plurality of sets of corresponding relationships between transmit power difference parameters with different sizes and transmit power sets may be configured in the SAR idle set in sequence according to the step values.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 9db, the number of the SAR null sets is 15, the maximum transmission power difference parameter corresponding to the device is determined to be 6db, and the division by the number of the SAR null sets is equal to 0.4db, which indicates that the step value of the transmission power difference parameter is 0.4 db. Further, starting from the minimum transmission power difference parameter, a first group of transmission power groups with the transmission power difference parameter of 0.4db can be configured in the SAR idle group; the second group is a transmitting power group with a transmitting power difference parameter of 0.8 db; ...; and the 15 th group of the transmission power groups with the transmission power difference parameter of 6db just multiplexes all the SAR idle groups.
In other embodiments, in practical applications, a researcher may preset a step value of the transmission power difference parameter based on experience, and in this case, there may be a case where the configuration of the correspondence relationship between the transmission power difference parameter and the transmission power group only needs to multiplex a part of the SAR idle groups, or the SAR idle groups are not sufficient to store a plurality of sets of correspondence relationships between transmission power difference parameters of different sizes and the transmission power group.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 9db, the step value of the preset transmission power difference parameter by the researcher is 0.5db, and assuming that there are 15 SAR idle groups and the maximum transmission power difference parameter corresponding to the device is 6db, starting from the minimum transmission power difference parameter, a first group of transmission power groups with the transmission power difference parameter of 0.5db can be configured in the SAR idle groups; the second group is a transmitting power group with a transmitting power difference parameter of 1 db; ...; a 12 th set of transmissions having a transmit power difference parameter of 6 db.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 9db, the step value of the preset transmission power difference parameter by the researcher is 0.3db, and assuming that there are 15 SAR idle groups and the maximum transmission power difference parameter corresponding to the device is 6db, starting from the minimum transmission power difference parameter, a first group of transmission power groups with the transmission power difference parameter of 0.3db can be configured in the SAR idle groups; the second group is a transmitting power group with a transmitting power difference parameter of 0.6 db; ...; the 15 th group of the transmitting power group with the transmitting power difference parameter of 4.5db is not enough to store the corresponding relation between a plurality of groups of transmitting power difference parameters and transmitting power groups, so that a configuration group can be automatically created in the equipment registry for presetting the corresponding relation between the transmitting power difference parameters and the transmitting power groups.
In some embodiments, it may be ensured that the transmission power of one of the two antennas does not change, and the configuration of the corresponding relationship between the plurality of sets of transmission power difference parameters with different sizes and the transmission power set is realized based on the change of the transmission power of the other antenna; or the configuration of the corresponding relationship between a plurality of groups of transmission power difference parameters with different sizes and the transmission power group can be realized based on the simultaneous change of the transmission power of the two antennas.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 10db, the researcher presets a step value of the transmission power difference parameter to be 0.5db, at this time, the first antenna power 15db remains unchanged, and starting from the minimum transmission power difference parameter, a first group of transmission power groups with the transmission power difference parameter of 0.5db can be configured in the SAR idle group, and the first group of transmission power groups includes the first antenna transmission power 15db and the second antenna transmission power 14.5 db; the second group is a transmitting power group with a transmitting power difference parameter of 1db, and comprises a first antenna transmitting power of 15db and a second antenna transmitting power of 14 db; the third group is a transmitting power group with a transmitting power difference parameter of 1.5db, and comprises a first antenna transmitting power of 15db and a second antenna transmitting power of 13.5db, and so on, so as to obtain the corresponding relation between multiple groups of transmitting power difference parameters with one antenna transmitting power unchanged and the transmitting power group.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 10db, and the researcher presets a step value of the transmission power difference parameter to be 0.5db, where the first antenna power and the second antenna power change simultaneously, and starting from the minimum transmission power difference parameter, a first group of transmission power groups with a transmission power difference parameter of 0.5db may be configured in the SAR idle group, where the first group includes the first antenna transmission power of 15db and the second antenna transmission power of 14.5 db; the second group is a transmitting power group with a transmitting power difference parameter of 1db, and comprises a first antenna transmitting power of 14.5db and a second antenna transmitting power of 13.5 db; the third group is a transmitting power group with a transmitting power difference parameter of 1.5db, and comprises a first antenna transmitting power of 14db and a second antenna transmitting power of 12.5db, and so on, so as to obtain the corresponding relation between the transmitting power difference parameters and the transmitting power group, wherein the transmitting powers of the two antennas change simultaneously.
Specifically, based on the foregoing embodiment, fig. 5 is a third example of an implementation flow of the power adjustment method according to the embodiment of the present invention, as shown in fig. 5, the method for the power adjustment device to adjust the first current transmission power corresponding to the first antenna and/or the second current transmission power corresponding to the second antenna according to the adjustable transmission power difference parameter may include the following steps:
s103a, determining an adjustable transmission power group corresponding to the adjustable transmission power difference parameter according to the corresponding relation between the transmission power difference parameter configured in the SAR configuration group and the transmission power group.
S103b, adjusting the first current transmit power according to the first transmit power in the adjustable transmit power set, and/or adjusting the second current transmit power according to the second transmit power in the adjustable transmit power set.
In this embodiment of the present invention, the power adjusting device may further match an adjustable transmit power group from a corresponding relationship between a preset transmit power difference parameter and the transmit power group based on a current transmit power difference parameter between the two antennas determined by the current RSSI difference value, that is, adjust power for at least one of the first antenna and the second antenna.
Based on the above-mentioned S104a to S104d, it may be implemented that the difference parameter of different transmission powers is set to correspond to different transmission power groups based on the change of the transmission power of the other antenna, so as to ensure that the transmission power of one of the two antennas does not change; or setting different transmission power difference parameters corresponding to different transmission power groups can be realized based on the simultaneous change of the transmission power of the two antennas. Correspondingly, the current transmitting power of the first antenna can be adjusted according to the first transmitting power in the determined adjustable transmitting power group; or adjusting the current transmitting power of the second antenna according to the determined second transmitting power in the adjustable transmitting power group; or adjusting the current transmitting power of the first antenna according to the first transmitting power in the determined adjustable transmitting power group and adjusting the current transmitting power of the second antenna according to the second transmitting power in the determined adjustable transmitting power group so as to realize the consistency of the antenna radiation performance.
It should be understood that, in practical applications, the antenna transmission power difference parameter determined based on the RSSI difference value cannot be completely matched in the preset correspondence between the transmission power difference parameter and the transmission power group, so that the preset range of the current transmission power difference parameter can be expanded, and thus a group of adjustable transmission power groups can be completely matched in the correspondence between the preset transmission power difference parameter and the transmission power group based on the expanded transmission power difference parameter.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 10db, and the step value of the transmission power difference parameter is 0.5db, including the first antenna transmission power of 15db and the second antenna transmission power of 14.5 db; the second group is a transmitting power group with a transmitting power difference parameter of 1db, and comprises a first antenna transmitting power of 15db and a second antenna transmitting power of 14 db; and the third group is a transmitting power group with a transmitting power difference parameter of 1.5db, and comprises a transmitting power of 15db of the first antenna and a transmitting power of 13.5db of the second antenna, and so on, if the transmitting power difference parameter determined based on the current RSSI difference value is 1.4db, and no completely matched corresponding relation exists, therefore, the 1.4db can be expanded by 0.1db to obtain 1.5db, and the third group is a transmitting power group with a transmitting power difference parameter of 1.5db, and comprises a transmitting power of 15db of the first antenna and a transmitting power of 13.5db of the second antenna as a target adjustable transmitting power group, and the power of the first antenna is kept unchanged, and the gain difference between the antennas is offset by adjusting the power of 13.5db of the second antenna so that the transmitting power difference value of 1.5db is obtained, and the radiation performance of south counties of the two branches is consistent.
