Data transmission method and terminal

Abstract

The invention discloses a data transmission method and a terminal. The terminal establishes short-distance wireless communication with one or multiple internet of things terminals. The diversity antenna of the terminal is combined with the antennas of the internet of things terminals so as to obtain multiple antenna combinations. The signal / data parameters of multiple antenna combinations are compared, and the antenna combination with the optimal signal / data parameters is selected. The terminal performs data transmission with a base station through the selected antenna combination. The connection mode adopted between the terminal and the internet of things terminals is the more stable short-distance wireless connection so that the quite stable data throughput service can be provided. Besides, the internet of things terminals are dispersedly distributed, antenna performance of the internet of things terminals is better than that of the terminal, and the antenna combination with the optimal signal / data parameters is selected from the antenna combinations of the terminal and the internet of things terminals to perform data interaction with the base station, and thus data throughput of the terminal can be enhanced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data transmission method and a terminal. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) on mobile phones or other data terminals is composed of two LTE antennas carried by the mobile phone or other data terminals to achieve data communication. The LTE antenna is divided into a main antenna and a diversity antenna. Currently, the main antenna performs For data transmission, the main antenna and the diversity antenna perform data reception at the same time. With the evolution of LTE technology, both the main antenna and the diversity antenna can also transmit and receive data. [0003] However, the design trend of mobile phones or other terminals is thin and small. The headroom or height required for the good electrical performance of the two antennas of the LTE main set and diversity sets will be increasingly restricted. Poor an...

Problems solved by technology

[0003] However, the design trend of mobile phones or other terminals is thin and small. The headroom or height required for the good electrical performance of the two antennas of the LTE main set and the diversity set will be increasingly restricted. Poor antenna performance will inevitably greatly reduce the performance of LTE. data throughput

Under the influence of human hands, mobile phones will randomly block the two antennas of LTE, and the performance of LTE will also deteriorate, and the throughput will also deteriorate.
