Detailed Description
The present application will be further described in detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present application more apparent, and the described embodiments should not be construed as limiting the present application, and all other embodiments obtained by those skilled in the art without making any inventive effort are within the 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 to be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with one another without conflict.
In the following description, the terms "first", "second", "third" and the like are merely used to distinguish similar objects and do not represent a specific ordering of the objects, it being understood that the "first", "second", "third" may be interchanged with a specific order or sequence, as permitted, to enable embodiments of the application described herein to be practiced otherwise than as illustrated 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 application only and is not intended to be limiting of the application.
Before explaining the embodiments of the present disclosure in further detail, terms and terminology involved in the embodiments of the present disclosure are explained, and the terms and terminology involved in the embodiments of the present disclosure are applicable to the following explanation.
1) Received signal strength indication (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 received channel bandwidth, in dB (and one unit of sound size level), is a logarithmic criterion, not linear.
2) Antenna transmit power: the transmission power of radio waves refers to energy in a given frequency band range.
3) Antenna gain: refers to the ratio of the radiated power flux density of the antenna in a given direction to the radiated power density of the reference antenna (typically using an ideal point source). Quantitatively describes how much input power is concentrated by an antenna, and simply the antenna gain refers to the ability of an antenna to transmit and receive signals in a particular direction.
4) Antenna radiation performance: referring to the total energy transmitted by an antenna, since electromagnetic wave energy in a wireless system is generated by the superposition of the transmitted energy of a transmitting device and the amplification of the antenna, the total energy transmitted by the antenna = antenna transmit power + antenna gain is measured.
5) Specific absorption rate (Specific Absorption Rate SAR): the electromagnetic wave absorption ratio or absorption ratio is the electromagnetic wave energy absorption ratio of a mobile phone or a wireless product, and is positioned so that an electromagnetic field is 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, in vivo electromagnetic fields will generate electrical currents, resulting in absorption and dissipation of electromagnetic energy. SAR is commonly used in biopharmacology to characterize this physical process. SAR is the electromagnetic power absorbed or consumed by human tissue per unit mass, and the unit is W/kg. Specific Absorption Rate (SAR) tables are typically configured and stored in a registry of devices for mobile broadband modems in the related art.
6) MIMO: the technology that a plurality of transmitting antennas and receiving antennas are respectively used at a transmitting end and a receiving end can doubly improve the capacity and the frequency spectrum utilization rate of a communication system under the condition of not increasing the bandwidth is applied to WiFi.
At present, two antennas are generally adopted for data transmission in uplink MIMO, so that the best throughput rate is achieved by effectively avoiding error code retransmission of data, and the consistent radiation performance of the two antennas is required to be ensured as much as possible.
However, in the actual use process, although the antenna transmitting power is basically the same, in the actual use process, the antenna radiation performance is often different due to different antenna gains caused by different antenna positions, and in the actual use process of a user, factors such as the placement position of a mobile phone or a wireless device or shielding of hands of the user also cause the radiation performance of two antennas to be deviated, thereby further causing the defect of reduced data transmission performance.
For example, fig. 1 is a schematic view of a scenario affecting the radiation performance of an antenna, as shown in fig. 1, where the device 100 configures a first antenna ANT1 and a second antenna ANT2, as shown in fig. 1, where the two antennas correspond to different positions, and where the antenna ANT2 is blocked by a human hand.
In view of this, how to adjust the uniformity of the radiation performance of the antenna is discussed in the following 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 transmitting power difference parameter between the first antenna and the second antenna based on the RSSI difference; and further, according to the adjustable transmitting power difference parameter, adjusting the first current transmitting power corresponding to the first antenna and/or the second current transmitting power corresponding to the second antenna. Therefore, the transmitting power between the two antennas can be dynamically adjusted through the RSSI difference value between the two antennas, so that the deviation of the radiation performance between the antennas caused by the difference of the antenna positions, the difference of the gains and the shielding of the hands can be balanced, the radiation performance of the two antennas is consistent, and the data transmission performance is further improved.
The power regulation method provided by the embodiment of the application is applied to power regulation equipment. The exemplary application of the power adjustment device provided by the embodiment of the application is described below, and the power adjustment device provided by the embodiment of the application can be implemented as a mobile phone, a notebook computer, a tablet computer, a desktop computer, an intelligent television, a vehicle-mounted device, a wearable device, a router, an industrial device and the like, wherein the power adjustment device is configured with a plurality of radio frequency antennas to support the 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 diagram of an implementation flow of the power adjustment method provided in the embodiment of the present application, 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 value, so when the radiation performance of the plurality of antennas of the device is inconsistent due to the position of the antennas and the shielding, the inconsistent phase change of the RSSI values between the antennas can be relied on to reflect the inconsistent radiation performance between the antennas. Therefore, in the embodiment of the application, in order to reflect the difference of the current radiation performance of different antennas, the power adjustment device may first determine the RSSI difference between the different antennas.
In the embodiment of the present application, an exemplary description of the power adjustment method is given by taking two antennas as examples.
Specifically, when the MIMO works, the power adjusting device may grab the RSSI values corresponding to the two antenna paths in real time, including the first RSSI value corresponding to the first antenna and the second RSSI value corresponding to the second antenna, and further perform a difference operation to determine the RSSI difference between the two antennas.
It will be appreciated that there will be a difference in RSSI values between the first antenna and the second antenna when either the MIMO antenna is obscured by a human hand or by the presence of an obstruction. For example, as shown in fig. 3, a first antenna ANT1 disposed in the electronic device corresponds to a first RSSI value, a second antenna ANT2 corresponds to a second RSSI value, and when the second antenna is blocked by a human hand, there is a difference between the first RSSI value and the second RSSI value.
S102, determining an adjustable transmitting power difference parameter between the first antenna and the second antenna based on the RSSI difference.
In the embodiment of the invention, after the RSSI difference value between the two antennas is determined, the difference of the radiation performance between the two antennas can be reflected based on the RSSI difference value, and at the moment, the adjustment of the difference of the antenna performance is required to be further executed so as to realize the consistency of the radiation performance of the two antennas.
Specifically, an adjustable transmit power difference parameter between antennas may be determined based on the RSSI difference.
It should be understood that the total antenna transmit energy = antenna transmit power + antenna gain, that is, two days determining the antenna radiation performance include the antenna transmit power and the antenna gain; in general, the transmitting power of different antennas of the MINO is controlled by the device autonomously, which is a fixed quantity, and can be controlled to be consistent, and then the key factor causing inconsistent antenna radiation performance is the antenna gain, that is, the difference of RSSI values between two antennas essentially reflects the difference of the antenna gains between the two antennas.
The antenna gain difference is caused by the antenna position, the equipment position, the shielding of the hands, and the like, and the situation of how the equipment is placed, how the hands touch the equipment, and the like cannot be determined, so that the adjustment of the antenna gain difference between the two antennas cannot be accurately realized.
Therefore, in the embodiment of the invention, the transmitting power of the two antennas can be adjusted, namely the transmitting power of the two antennas becomes a variable, so that the difference value of the transmitting power between the adjusted antennas can offset the difference value of the antenna gains between the antennas, thereby compensating the condition that the radiation performance is inconsistent due to the antenna gains, and enabling the radiation performance corresponding to the first antenna to be consistent with the radiation performance corresponding to the second antenna.
In view of the fact that the determined RSSI difference between the first antenna and the second antenna can basically reflect the difference of gains between the antennas, if the difference of the gains of the antennas cannot be accurately adjusted by adopting corresponding means, if the radiation performance of the first antenna and the radiation performance of the second antenna are to be ensured to be consistent, the difference of the transmitting power between the first antenna and the second antenna can be further determined based on the RSSI difference between the antennas, and the difference of the transmitting power and the difference of the gains of the antennas are utilized to cancel each other.
Specifically, a difference parameter of the transmitting power between the antennas may be determined based on the RSSI difference between the antennas, where the transmitting power difference parameter may represent the transmitting power difference between the antennas.
In an embodiment, the transmission power difference parameter may be in the same unit of measurement as the RSSI difference and in a different unit of measurement from the antenna transmission power difference; if the measurement unit of the RSSI value is db, the measurement unit of the antenna transmitting power is mW, and the measurement units of the RSSI difference and the antenna transmitting power difference are not the same, therefore, the antenna transmitting power difference parameter with the same measurement unit can be determined based on the RSSI difference, and then conversion between the measurement unit db and mW is carried out, so that the antenna transmitting power difference with the mW is obtained.
In another embodiment, the antenna transmission power measurement unit may be directly represented by the measurement unit dB after being converted by the units of mW and dB, that is, the unit of transmission power may be directly represented by dB, and then the antenna transmission power difference parameter may be directly equal to the antenna transmission power difference.
For example, in the case where 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, and 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 radiation performance of the second antenna are the same, TX power2-TX power 1=rssi 2-RSSI1, that is, the power difference=rssi difference may be made.
S103, 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.
In the embodiment of the invention, after the adjustable transmitting power difference parameter between the first antenna and the second antenna is determined based on the RSSI difference, the transmitting power difference of the antennas needs to be further adjusted based on the difference parameter.
Specifically, an adjustable transmission power difference between two antennas can be determined based on an adjustable transmission power difference parameter, and then adjustment of the transmission power of at least one of the two antennas is realized based on the difference.
In some embodiments, the transmitting power of the first antenna may be fixed without changing, and the transmitting power difference between the first antenna and the second antenna may be adjusted by adjusting the transmitting 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 transmitting power of the second antenna may be fixed without changing, and the transmitting power difference between the first antenna and the second antenna is adjusted by adjusting the transmitting power of the first 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 still other embodiments, the transmission power of the first antenna and the transmission power of the second antenna may be changed at the same time, and the transmission power difference between the first antenna and the second antenna may be adjusted by adjusting the transmission power of the first antenna and the transmission power of the second antenna, so as to further cancel the difference value caused by the antenna gain between the antennas, so that the radiation performance of the two antennas is 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 transmitting power difference parameter between the first antenna and the second antenna based on the RSSI difference; and further, according to the adjustable transmitting power difference parameter, adjusting the first current transmitting power corresponding to the first antenna and/or the second current transmitting power corresponding to the second antenna. Therefore, the transmitting power between the two antennas can be dynamically adjusted through the RSSI difference value between the two antennas, so that the deviation of the radiation performance between the antennas caused by the difference of the antenna positions, the difference of the gains and the shielding of the hands can be balanced, 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 steps of:
S104, configuring the corresponding relation between the transmission power difference parameter and the transmission power group in the empty group of the electromagnetic wave absorption ratio SAR configuration group; wherein one transmit power difference parameter corresponds to one transmit power group; one transmit power group includes a first transmit power and a second transmit power.
In the embodiment of the invention, the corresponding relation between the transmitting power difference parameter and the transmitting power group can be preconfigured; each transmission power difference parameter corresponds to a transmission power group, one transmission power group comprises a first transmission power and a second transmission power, and at least one of the transmission power groups comprises a first antenna transmission power and a second transmission power which are different.
In some embodiments, the SAR configuration group may be multiplexed, and a correspondence between the preset transmission power difference parameter and the transmission power group may be stored in the SAR configuration group.
It should be understood that, in the related art, a Specific Absorption Rate (SAR) table, that is, a SAR configuration group, is often configured and stored in a registry of a mobile phone or a wireless device for configuring SAR power in different states, where the SAR configuration group has a part of an empty group, and we can multiplex the part of the empty group, and configure a preset correspondence between a transmission power difference parameter and a transmission power group in the empty group in the SAR configuration group.
For example, a platform at high altitude contains up to 36 sets of SAR configurations, so that 18 SAR power configurations in different states can be realized, usually only 1-3 sets of SAR configurations are needed to complete normal SAR functions, and the other 15 sets are empty, so that the 15 sets of empty sets can be multiplexed, and the corresponding relation between the preset transmission power difference parameter and the transmission power set is configured in the SAR empty sets.
Even if the SAR configuration groups are all empty, especially in PRC project, since no SAR test is needed, we can multiplex all SAR configuration groups.
In other embodiments, the power adjustment device, such as a mobile phone or a wireless device, may also open up a new configuration set in its own registry to store the configuration of the correspondence between the preset transmission power difference parameter and the transmission power set, which is not limited in the present application.
Specifically, based on the above embodiment, fig. 4 is a schematic diagram of an implementation flow example of a power adjustment method according to an embodiment of the present application, and as shown in fig. 4, a method for configuring a correspondence between a transmission power difference parameter and a transmission power group in an empty group of a SAR configuration group includes the following steps:
s104a, determining the maximum transmission power and the minimum transmission power according to the current equipment type, and calculating an initial power difference value between the maximum transmission power and the minimum transmission power.
S104b, determining a step value of the transmit power difference parameter based on the initial power difference and the number of empty groups.
And S104c, constructing a 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 stepping value of the transmission power difference parameter.
S104d, configuring the corresponding relation between the transmission power difference parameter and the transmission power group in the empty group; and configuring a corresponding relation between a transmitting power difference parameter and the transmitting power group in each empty group.
In the embodiment of the invention, when the corresponding relation between the multiple groups of transmission power difference parameters and the transmission power groups is configured by multiplexing the SAR empty groups, the corresponding relation can be configured based on multiple preset configuration strategies.
In an embodiment, the configuration of the correspondence may be performed by using a preset configuration policy that multiplexes all SAR empty groups.
Specifically, the current device type may be determined first, the corresponding maximum transmission power and 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, may be calculated.
It can be understood that if all SAR empty groups are to be multiplexed, i.e. a transmission power group corresponding to a transmission power difference value of one size is configured in each empty group, at this time, the number of SAR empty groups is determined first, then a maximum transmission power difference parameter corresponding to the maximum transmission power difference value is determined based on the conversion of the measurement unit, and further a step value of the transmission power difference value, 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 SAR empty groups. Here, the larger the maximum transmit power difference parameter, the fewer the null groups, the larger the corresponding step values, and conversely the more the null groups, the smaller the corresponding step values.
Further, the minimum transmission power difference parameter can be used as a starting point, and the corresponding relation between the transmission power difference parameters with different sizes and the transmission power groups can be configured in the SAR empty group according to the stepping value.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 9db, the number of SAR empty groups is 15, the maximum transmission power difference parameter corresponding to the device is determined to be 6db, and the number of SAR empty groups divided by the maximum transmission power difference parameter is equal to 0.4db, which indicates that the step value of the transmission power difference parameter is 0.4db. Further, starting from the minimum transmission power difference parameter, a first transmission power group with the transmission power difference parameter of 0.4db can be configured in the SAR empty group; the second group is a transmitting power group with a transmitting power difference parameter of 0.8 db; ... The 15 th group of transmitting power difference parameter is the transmitting power group of 6db, and all the idle SAR groups are just multiplexed.
In other embodiments, in practical applications, a researcher may preset a step value of the transmission power difference parameter based on experience, in which case, only a part of SAR empty groups may be multiplexed for configuring the corresponding relationship between the transmission power difference parameter and the transmission power group, or the SAR empty groups may not store the corresponding relationship between multiple sets of transmission power difference parameters with different magnitudes and the transmission power group.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 9db, the stepping value of the preset transmission power difference parameter of the researcher is 0.5db, assuming that 15 idle sets of SAR are provided, the maximum transmission power difference parameter corresponding to the device is 6db, starting from the minimum transmission power difference parameter, the first set of transmission power sets with the transmission power difference parameter of 0.5db can be configured in the idle sets of SAR; the second group is a transmitting power group with a transmitting power difference parameter of 1 db; ... The 12 th group of transmissions with a transmit power difference parameter of 6db, for example.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 9db, the stepping value of the preset transmission power difference parameter of the researcher is 0.3db, assuming that 15 idle sets of SAR are provided, the maximum transmission power difference parameter corresponding to the device is 6db, starting from the minimum transmission power difference parameter, the first set of transmission power sets with the transmission power difference parameter of 0.3db can be configured in the idle sets of SAR; the second group is a transmitting power group with a transmitting power difference parameter of 0.6 db; ... The 15 th group of transmitting power difference parameters is a transmitting power group with 4.5db, and the SAR empty group is insufficient to store the corresponding relation between the transmitting power difference parameters and the transmitting power group, so that a configuration group can be opened up in the equipment registry by itself for carrying out the corresponding relation between the preset transmitting power difference parameters and the transmitting power group.
In some embodiments, it may be that one of the two antennas is guaranteed not to change, and a plurality of sets of transmission power difference parameters with different sizes and a corresponding relation of the transmission power sets are configured based on the change of the transmission power of the other antenna; the configuration of the corresponding relation between the transmission power difference parameters with different magnitudes and the transmission power groups 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 stepping value of the preset transmission power difference parameter of the researcher is 0.5db, the first antenna power 15db is kept unchanged at this time, the transmission power group with the transmission power difference parameter of 0.5db can be configured in the idle SAR group from the minimum transmission power difference parameter, and the transmission power group comprises the transmission power 15db of the first antenna and the transmission power 14.5db of the second antenna; the second group is a transmission power group with a transmission power difference parameter of 1db, and comprises a first antenna transmission power of 15db and a second antenna transmission power of 14db; 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 the corresponding relation between a plurality of groups of transmitting power difference parameters with the same transmitting power of one antenna and the transmitting power group is obtained by the same way.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 10db, the stepping value of the preset transmission power difference parameter of the researcher is 0.5db, the first antenna power and the second antenna power are simultaneously changed, and the first transmission power group with the transmission power difference parameter of 0.5db can be configured in the idle SAR group from the minimum transmission power difference parameter, and the transmission power group comprises the transmission power of 15db of the first antenna and the transmission power of 14.5db of the second antenna; the second group is a transmission power group with a transmission power difference parameter of 1db, and comprises 14.5db of the transmission power of the first antenna and 13.5db of the transmission power of the second antenna; the third group is a transmitting power group with a transmitting power difference parameter of 1.5db, and comprises a transmitting power of 14db of the first antenna and a transmitting power of 12.5db of the second antenna, and the like, so as to obtain the corresponding relation between the transmitting power difference parameter and the transmitting power group of multiple groups, wherein the transmitting power of the two antennas is changed at the same time.
Specifically, based on the foregoing embodiments, fig. 5 is a schematic diagram of an implementation flow example of a power adjustment method according to the embodiment of the present invention, and as shown in fig. 5, a method for adjusting, by a power adjustment device, a first current transmission power corresponding to a first antenna and/or a second current transmission power corresponding to a second antenna according to an 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 transmission power according to the first transmission power in the adjustable transmission power group, and/or adjusting the second current transmission power according to the second transmission power in the adjustable transmission power group.
In the embodiment of the present invention, the power adjustment device may further match the adjustable transmission power group from the correspondence between the preset transmission power difference parameter and the transmission power group, that is, the adjustment power for at least one of the first antenna and the second antenna, based on the current transmission power difference parameter between the two antennas determined by the current RSSI difference.
Based on the above-mentioned S104a to S104d, it may be ensured that the transmission power of one of the two antennas is not changed, and setting different transmission power difference parameters corresponding to different transmission power groups is realized based on the change of the transmission power of the other antenna; setting different transmission power difference parameters to correspond to different transmission power groups can also be realized based on simultaneous changes of transmission power of two antennas. Correspondingly, the current transmission power of the first antenna can be adjusted according to the determined first transmission power in the adjustable transmission power group; or adjusting the current transmission power of the second antenna according to the determined second transmission power in the adjustable transmission power group; or adjusting the current transmission power of the first antenna according to the determined first transmission power in the adjustable transmission power group and adjusting the current transmission power of the second antenna according to the determined second transmission power in the adjustable transmission power group so as to achieve the consistency of the radiation performance of the antennas.
It should be understood that, because in practical application, the antenna transmission power difference parameter determined based on the RSSI difference cannot be completely matched in the corresponding relationship between the preset transmission power difference parameter and the transmission power group, we can expand the preset range of the current transmission power difference parameter, so that based on the expanded transmission power difference parameter, a group of adjustable transmission power groups can be completely matched from the corresponding relationship between the preset transmission power difference parameter and the transmission power group.
For example, the maximum transmission power of the device is 15db, the minimum transmission power is 10db, the step value of the transmission power difference parameter is 0.5db, and the step value comprises the transmission power of the first antenna 15db and the transmission power of the second antenna 14.5db; the second group is a transmission power group with a transmission power difference parameter of 1db, and comprises a first antenna transmission power of 15db and a second antenna transmission power of 14db; the third group is a transmission power group with a transmission power difference parameter of 1.5db, and comprises a transmission power 15db of a first antenna and a transmission power 13.5db of a second antenna, and so on, if the transmission power difference parameter determined based on the current RSSI difference is 1.4db, and no corresponding relation of complete matching exists, therefore, 0.1db expansion can be carried out on the 1.4db to obtain 1.5db, and further the third group is a transmission power group with the transmission power difference parameter of 1.5db, and comprises a transmission power 15db of the first antenna and a transmission power 13.5db of the second antenna as target adjustable transmission power groups, and the transmission power of the first antenna is kept unchanged, and the transmission power difference of the antennas is 1.5db by adjusting the transmission power of the second antenna to offset the gain difference between the antennas, so that the radiation performance of two counties is consistent.
The embodiment of the application provides a power adjusting method, which can pre-configure the corresponding relation between a plurality of groups of different antenna transmitting power difference parameters and transmitting power groups, and further determine the adjusting value of the transmitting power of at least one of a first antenna and a second antenna based on the corresponding relation, so as to offset the antenna gain difference based on the antenna transmitting power difference, and realize the consistency of the radiation performance of the two antennas.
