Terminal and communication method thereof

Abstract

The invention provides a terminal and a communication method thereof. The terminal specifically comprises a baseband processing module, a data comprehensive processing module, a wireless transceiver module, a radio frequency front end module and an antenna. The data comprehensive processing module is connected between the baseband processing module and the wireless transceiver module. The data comprehensive processing module comprises a function enhancing sub module used for conducting number predistortion processing according a baseband signal output by the baseband processing module and a radio frequency signal, after power amplifying processing and fed back through a receiving channel, of the wireless transceiver module. The radio frequency front end module comprises a power amplifying sub module and a coupling sub module. The power amplifying sub module is used for conducting the power amplifying processing to the radio frequency signal output by the wireless transceiver module through a Doherty structure, and the radio frequency signal after the power amplifying processing is sent out through the antenna. The coupling sub module is used for obtaining the radio frequency signal after the power amplifying processing in a coupling mode. According to the terminal and the communication method thereof, power amplifying efficiency is improved and therefore uploading power consumption of the terminal is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a terminal and a communication method thereof. Background technique [0002] At present, the continuous and rapid upgrading, evolution and diversification of wireless communication technologies have also put forward higher requirements for corresponding terminals. For example, the communication function of the terminal has become more powerful. In addition to the traditional voice service, high-speed data service has gradually become an essential function of the terminal. These more powerful and newly added functions also put forward more important requirements for the power saving design of the terminal. , at the same time, terminal power consumption is also one of the terminal performances that users are most concerned about. [0003] refer to figure 1 , shows a schematic structural diagram of a terminal in the prior art, which may specifically include ...

AI Technical Summary

Problems solved by technology

[0005] According to the relationship of efficiency = output power / power consumption, when the terminal is working in the transmitting mode, if the efficiency of the power amplifier is very low, the power consumption of the entire terminal will be large; and in the case of high power consumption, power supply and heat dissipation are not conducive Reduce the size of the terminal, and the power consumption will affect the standby time of the terminal; therefore, the power efficiency is low, and it is not suitable for applications with small size and long standby time, which has caused many restrictions on the use scenarios of the terminal
