Abstract

The invention discloses a method and terminal supporting carrier aggregation. The terminal comprises a radio frequency front-end device. The radio frequency front-end device comprises an antenna switch. The terminal also comprises a multiband antenna assembly. The multiband antenna assembly supports N work frequency bands. The multiband antenna assembly includes a radiator, N feeding points and N matching networks. The radiator is electrically connected to the N feeding points. Each of the N feeding points is electrically connected to one output end of the antenna switch through one corresponding matching network. The antenna switch includes N output ends, N being integer greater than or equal to 2. A Diplexer in a radio frequency link can be omitted, so the path loss of a wireless link can be obviously reduced, and the radio frequency performance of the terminal is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and terminal for supporting carrier aggregation. Background technique [0002] With the rapid development of communication technology, the 4th generation mobile communication represented by LTE is being widely used, and the number of mobile terminals and the demand for throughput are also increasing. At present, the main demand for mobile communication comes from the rapid development of the mobile Internet, especially the development of smart terminals has stimulated a surge in mobile communication data traffic. In the future, more types of terminals will be introduced into the mobile communication network. The number of mobile communication terminals will far exceed the population, and data services will become the absolute mainstream. [0003] In order to improve the capacity and data throughput of mobile communication systems, in the past 30 years, there are mainly...
