Embodiment Construction

[0034] In order to solve the problem in the prior art that the actual network rate is low due to the large attenuation of high-frequency wireless electromagnetic waves, the present invention provides a method, device and mobile terminal for dynamically adjusting the working mode of the radio frequency front end. When using long-term evolution (Long Term Evolution, LTE) high-frequency signals, the distance between the mobile terminal and the base station is calculated by obtaining the positions of the mobile terminal and the base station, and when the distance exceeds the effective information that the mobile terminal can transmit uplink At the maximum distance, turn on the high transmission mode of the mobile terminal, so that the RF front end of the mobile terminal works in the high transmission mode, so as to ensure that the data sent by the mobile terminal at high frequency can be received by the base station, so as to improve the demodulation efficiency of the base station, ...

Abstract

The invention discloses a method and device for dynamically adjusting a working mode of a radio frequency front end, and a mobile terminal. The method comprises the following steps: when the mobile terminal uses a high frequency signal of Long Term Evolution LTE, calculating the distance between the mobile terminal and a base station by acquiring the positions of the mobile terminal and the base station; and when the distance exceeds a maximum distance of uplink transmissive effective information of the mobile terminal, starting a high emission mode of the mobile terminal, and enabling the radio frequency front end of the mobile terminal to work under the high emission mode, so as to ensure that data sent by the mobile terminal at high frequency can be received by the base station, so thatthe demodulation efficiency of the base station is improved, and the problem that the actual network rate is low due to the fact that high-frequency radio electromagnetic wave attenuation is large inthe prior art is solved.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method, device and mobile terminal for dynamically adjusting the working mode of a radio frequency front end. Background technique [0002] According to the characteristics of wireless electromagnetic wave transmission, the higher the frequency, the greater the signal attenuation on the straight-line propagation path. Taking the spectrum resources owned by Sprint as an example, the three spectrums owned by Sprint are sorted according to the attenuation: B26<B25<B41. B41 has the highest frequency and the largest attenuation. Among them, the attenuation of B25 is 3dB smaller than that of B41. B26 is 7.4dB smaller than B25. According to Sprint's actual network deployment statistics, under the same technical conditions, the network coverage of B41 is nearly 30% smaller than that of B25. [0003] From the perspective of Sprint's frequency resources, Sprint's spect...
