Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the development of economy and social progress, users have developed new demands for communication technology, such as higher communication rate to support the application of ultra high definition video, lower network latency to meet the control speed demand of autonomous driving telemedicine, greater connection capacity and traffic density to meet the demand of ubiquitous internet of things and coverage of hot spots, and the like. However, these requirements cannot be met based on the Evolution of LTE (long term Evolution) network architecture and technology and the current situation of LTE spectrum, and therefore, the 5G NR (New Radio) technology comes along. In order to achieve a higher communication bandwidth, the frequency range of the 5G NR band is developed toward higher frequencies, wider bandwidths. Currently, the 5G NR partial band defined by 3GPP (Third Generation Partnership Project) overlaps or is adjacent to a WiFi (Wireless Fidelity) band, in this case, if the 5G NR circuit of the mobile terminal and the WiFi circuit operate simultaneously, there may be strong mutual interference, and even damage to devices such as LNA (Low Noise Amplifier) may be caused. Therefore, a coexistence mechanism of the 5G NR band and the WiFi band is required.
In the prior art, the power reception of the 5G NR circuit is completely turned off when the WiFi circuit transmits power, and the power reception of the WiFi circuit is completely turned off when the 5G NR circuit transmits power. Although the mode can avoid the device damage in the coexistence scene, the overall communication rate of the 5G NR and the WiFi is sacrificed, so that the overall communication performance of the mobile terminal is reduced.
In order to solve the foregoing technical problems, embodiments of the present invention provide a power control method and an electronic device.
For ease of understanding, some concepts involved in embodiments of the present invention will be described first below.
The 5G (New Radio) is a global 5G standard designed based on a New air interface of an OFDM (Orthogonal Frequency Division Multiplexing) technology, and is also a very important cellular mobile technology basis for the next Generation, and the 5G technology will realize ultra-low latency and high reliability.

TABLE 2
Next, a power control method provided in an embodiment of the present invention is described.
It should be noted that, the method provided in the embodiment of the present invention is applicable to an electronic device, and in practical applications, the electronic device may include: a smart phone, a tablet computer, a smart watch, or a personal digital assistant, etc., which are not limited in the embodiments of the present invention.
Fig. 1 is a flow chart of a power control method according to an embodiment of the present invention, which may include the following steps, as described in fig. 1: a step 101 and a step 102, wherein,
in step 101, a first control signal and a second control signal are obtained, where the first control signal is one of a control signal in a 5G NR frequency band and a control signal in a WiFi frequency band, and the second control signal is the other of the control signal in the 5G NR frequency band and the control signal in the WiFi frequency band.
In the embodiment of the invention, when the first control signal is a control signal of a 5G NR frequency band, the second control signal is a control signal of a WiFi frequency band; when the first control signal is a control signal of a WiFi frequency band, the second control signal is a control signal of a 5G NR frequency band; the control signal is used to control the transmission and reception of the radio frequency signal, and specifically, the electronic device transmits the radio frequency signal in a transmission period (i.e., "TX period") of the control signal, and receives the radio frequency signal in a reception period (i.e., "RX period") of the control signal.
In the embodiment of the present invention, the related 5G NR frequency band and the WiFi frequency band are partially overlapped or adjacent, and the systems of the 5G NR frequency band and the WiFi frequency band are both TDD (Time Division Duplexing).
In the embodiment of the present invention, when the WiFi frequency band is a WiFi5G frequency band, the 5G NR frequency band may be one of frequency bands with frequency band numbers N77, N78, and N79; when the WiFi band is a WiFi 2.4G band, the 5G NR band may be one of bands with band numbers N38, N41, N50, and N51.
In the embodiment of the present invention, the first control signal and the second control signal are not completely synchronized, specifically, the TX period of the first control signal does not completely coincide with the RX period of the second control signal, the RX period of the first control signal does not completely coincide with the TX period of the second control signal, and the TX period of the first control signal does not completely coincide with the TX period of the second control signal.
In the embodiment of the present invention, the first control signal and the second control signal may be the same system clock signal, or may also be two system clock signals, and when the two system clock signals are used, the reference points of the two system clocks are the same.
In step 102, if the TX time period of one of the first control signal and the second control signal partially coincides with the RX time period of the other control signal, the transmission power of the communication band corresponding to the TX time period is switched from the preset first power level to the preset second power level at the starting time point of the coinciding time period.
In the embodiment of the present invention, the preset second power level is lower than the preset first power level, and the preset second power level is a power level that does not cause interference to a communication frequency band corresponding to an RX time period of the coincidence time period.
In an embodiment provided by the present invention, the step 102 may specifically include the following steps:
if the TX time period of the 5G NR frequency band is partially overlapped with the RX time period of the WiFi frequency band, switching the transmitting power of the 5G NR frequency band to a level which does not interfere with the RX signal time period of the WiFi frequency band at the initial time point of the overlapping of the TX time period of the 5G NR frequency band and the RX time period of the WiFi frequency band;
if the TX time interval of the WiFi frequency band is partially overlapped with the RX time interval of the 5G NR frequency band, the transmitting power of the WiFi frequency band is switched to the level which does not cause interference to the RX signal of the 5G NR frequency band at the initial time point when the TX time interval of the WiFi frequency band is overlapped with the RX time interval of the 5G NR frequency band.
For convenience of understanding, the technical solution of the embodiment of the present invention is described later by taking an example in which the 5G NR frequency band is an N79 frequency band and the WiFi frequency band is a WiFi5G frequency band.
Firstly, acquiring a control signal of an N79 frequency band and a control signal of a WiFi5G frequency band; then, according to the control signal of the N79 frequency band and the control signal of the WiFi5G frequency band, it is determined whether the TX time period of the N79 frequency band and the RX time period of the WiFi5G frequency band partially coincide, if yes, the transmission power of the N79 frequency band is reduced, specifically, the transmission power of the N79 frequency band is switched to a level that does not interfere with the reception of the radio frequency signal of the WiFi5G frequency band, for example, the transmission power of the N79 frequency band is switched to 12dbm, and at this time, there is no problem that the TX of the N79 frequency band interferes with the RX of the WiFi5G frequency band.
In addition, whether the TX time period of the WiFi5G frequency band is partially overlapped with the RX time period of the N79 frequency band is determined according to the control signal of the N79 frequency band and the control signal of the WiFi5G frequency band, if so, the transmitting power of the WiFi5G frequency band is reduced, specifically, the transmitting power of the WiFi5G frequency band is switched to a level which does not interfere with the receiving of the radio frequency signals of the N79 frequency band, and at the moment, the problem that the TX of the WiFi5G frequency band interferes with the RX of the N79 frequency band does not exist.
In one example, as shown in fig. 2, fig. 2 shows a control signal of an N79 frequency band and a control signal of a WiFi5G frequency band, and comparison shows that: the TX1 of the N79 frequency band control signal and the RX1 of the WiFi5G frequency band control signal are not overlapped at a time point, that is, there is no problem that the TX of the N79 frequency band interferes with the RX of the WiFi5G frequency band;
the TX2 of the N79 frequency band control signal and the RX2 of the WiFi5G frequency band control signal are overlapped at a time point, that is, there is a problem that the TX of the N79 frequency band interferes with the RX of the WiFi5G frequency band, and at a starting time point of the TX2 of the N79 frequency band control signal, the transmission power of the N79 frequency band is switched to 12dbm, so as to avoid the TX of the N79 frequency band interfering with the RX of the WiFi5G frequency band.
As can be seen from the above embodiment, in this embodiment, when the TX period of one of the control signal of the 5G NR band and the control signal of the WiFi band partially overlaps with the RX period of the other control signal, at the start time point of the overlapping period, the transmission power of the communication band corresponding to the TX period is switched to a power level that does not cause interference to the communication band corresponding to the RX period. Compared with the prior art, the embodiment of the invention can realize the simultaneous work of the 5G NR frequency band and the WiFi frequency band under the condition of ensuring that the 5G NR frequency band and the WiFi frequency band are not interfered with each other, thereby improving the overall communication rate.
Fig. 3 is a flowchart of a power control method according to another embodiment of the present invention, in which to further increase the overall communication rate, as shown in fig. 3, the method may include the following steps: step 301, step 302 and step 303, wherein,
in step 301, a first control signal and a second control signal are obtained, where the first control signal is one of a control signal in a 5G NR frequency band and a control signal in a WiFi frequency band, and the second control signal is the other of the control signal in the 5G NR frequency band and the control signal in the WiFi frequency band.
In the embodiment of the invention, when the first control signal is a control signal of a 5G NR frequency band, the second control signal is a control signal of a WiFi frequency band; when the first control signal is a control signal of a WiFi frequency band, the second control signal is a control signal of a 5G NR frequency band.
In the embodiment of the present invention, when the WiFi frequency band is a WiFi5G frequency band, the 5G NR frequency band may be one of frequency bands with frequency band numbers N77, N78, and N79; when the WiFi band is a WiFi 2.4G band, the 5G NR band may be one of bands having band numbers N38, N41, N50, and N51.
In step 302, if the TX time period of one of the first control signal and the second control signal partially coincides with the RX time period of the other control signal, the transmission power of the communication band corresponding to the TX time period is switched from the preset first power level to the preset second power level at the starting time point of the coinciding time period.
In the embodiment of the present invention, the preset second power level is lower than the preset first power level, and the preset second power level is a power level that does not cause interference to a communication frequency band corresponding to an RX time period of the coincidence time period.
In an embodiment provided by the present invention, the step 302 may specifically include the following steps:
if the TX time period of the 5G NR frequency band is partially overlapped with the RX time period of the WiFi frequency band, at the initial time point when the TX time period of the 5G NR frequency band is overlapped with the RX time period of the WiFi frequency band, the transmitting power of the 5G NR frequency band is switched to the level which does not interfere with the RX signal time period of the WiFi frequency band;
if the TX time period of the WiFi frequency band is partially overlapped with the RX time period of the 5G NR frequency band, the transmitting power of the WiFi frequency band is switched to the level which does not cause interference to the RX signal of the 5G NR frequency band at the initial time point when the TX time period of the WiFi frequency band is overlapped with the RX time period of the 5G NR frequency band.
In step 303, at the termination time point of the coincidence period, the transmission power of the communication frequency band corresponding to the TX period is switched from the preset second power level to the preset third power level.
In the embodiment of the present invention, the preset third power level is not lower than the preset first power level.
In an embodiment provided by the present invention, the step 303 may specifically include the following steps:
if the TX time period of the 5G NR frequency band is partially overlapped with the RX time period of the WiFi frequency band, the transmitting power of the 5G NR frequency band is increased at the termination time point of the overlapping of the TX time period of the 5G NR frequency band and the RX time period of the WiFi frequency band;
if the TX time period of the WiFi frequency band is partially overlapped with the RX time period of the 5G NR frequency band, the transmitting power of the WiFi frequency band is improved at the termination time point when the TX time period of the WiFi frequency band is partially overlapped with the RX time period of the 5G NR frequency band.
In a preferred embodiment of the present invention, the preset third power level is higher than the preset first power level; the sum of the power transmitted according to the preset second transmission power and the preset third transmission power in the preset time length is equal to the sum of the power transmitted according to the first transmission power in the preset time length.
Correspondingly, the step 303 may specifically include the following steps:
if the TX time period of the 5G NR frequency band partially coincides with the RX time period of the WiFi frequency band, at the termination time point of the coincidence of the TX time period of the 5G NR frequency band and the RX time period of the WiFi frequency band, the transmission power of the 5G NR frequency band is increased, and the loss of the reduction of the transmission power of the 5G NR frequency band in the coincidence time period is compensated, so that the total sum of the transmission power of the 5G NR frequency band is ensured to be constant within a preset time period (for example, 100 us).
If the TX time period of the WiFi frequency band is partially overlapped with the RX time period of the 5G NR frequency band, at the termination time point of the overlapping of the TX time period of the WiFi frequency band and the RX time period of the 5G NR frequency band, the transmitting power of the WiFi frequency band is improved, the loss of the reduction of the transmitting power of the WiFi frequency band in the overlapping time period is compensated, and therefore the sum of the transmitting power of the WiFi frequency band in the preset time period (for example, 100 us) is guaranteed to be unchanged.
For the convenience of understanding, the description is made in conjunction with the example of step 102 in the embodiment shown in fig. 1, for example, the preset duration is 100us, and the base station requires that the total transmission power P of the electronic devices within 100us satisfies: p = Ptx1+ Ptx2, wherein the relationship of P = Ptx1+ Ptx2 is shown in table 3 below:
Figure BDA0002288207490000121
Figure BDA0002288207490000131
TABLE 3
As shown in fig. 2, TX2 of the N79 band control signal coincides with RX2 of the WiFi5G band control signal at a time point, that is, there is a problem that TX of the N79 band interferes with RX of the WiFi5G band, at a starting time point of TX2 of the N79 band control signal, the transmission power of the N79 band is reduced to 12dbm, and at a next non-coinciding time point, the transmission power of the N79 band is increased to 14.4dbm, and a loss of the previous transmission power reduction is compensated, so that a sum of the transmission power of the N79 band is ensured to be unchanged within 100us of time, that is, about 17 dbm.
Therefore, in the embodiment of the invention, the transmitting power is switched to be within the threshold value at the time point with interference, so that the problem of interference at the same time point is avoided, the transmitting power is improved through the time point without interference, the power loss in the front is compensated, the total transmitting power of the electronic equipment is ensured to be unchanged, and the overall communication efficiency is improved.
As can be seen from the above embodiment, in this embodiment, when the TX period of one control signal of the 5G NR band and the control signal of the WiFi band partially overlaps with the RX period of the other control signal, at the start time point of the overlapping period, the transmission power of the communication band corresponding to the TX period is switched to a power level that does not cause interference to the communication band corresponding to the RX period; and at the termination time point of the coincidence time period, increasing the transmission power of the communication frequency band corresponding to the TX time period so as to compensate the previous power loss. Compared with the prior art, the embodiment of the invention can realize the simultaneous work of the 5G NR frequency band and the WiFi frequency band under the condition of ensuring that the 5G NR frequency band and the WiFi frequency band are not interfered with each other, thereby improving the overall communication rate.
