Problems solved by technology

At present, the existing technologies of terminal carrier aggregation in the industry are generally a combination of low-band (LowBand) and high-band (HighBand), which can realize in-band continuous carrier aggregation (Intra-CA). Existing solutions are all based on a 4-antenna architecture, but for terminals, 4-antenna carrier aggregation is hardly achievable

Abstract

The invention discloses a carrier aggregation device, which comprises a first transmitting and receiving antenna, a second transmitting and receiving antenna, a first radio frequency front end, a second radio frequency front end and a radio frequency transmitting and receiving chip, wherein signals received by the first transmitting and receiving antenna are divided into a way of high-frequency signals, a way of intermediate-frequency signals and a way of low-frequency signals through the first radio frequency front end, and the three ways of signals enter the radio frequency transmitting and receiving chip respectively; and signals received by the second transmitting and receiving antenna are divided into a way of high-frequency signals, a way of intermediate-frequency signals and a way of low-frequency signals through the second radio frequency front end, and the three ways of signals enter the radio frequency transmitting and receiving chip respectively.

Description

technical field [0001] The present invention relates to the technical field of multi-mode mobile communication, and in particular to a carrier aggregation device. Background technique [0002] With the advent of 4G communication technology, in order to support higher rates, 3GPP proposed LTE Advance (LTE-A), which can support more bandwidth combinations to achieve resource integration and increase data service rates, especially in limited frequency band resources. In some cases, carrier aggregation can significantly improve the data rate. At present, the existing technologies for terminal carrier aggregation in the industry are generally a combination of low-band (LowBand) and high-band (HighBand), which can realize in-band continuous carrier aggregation (Intra-CA). Existing solutions are all based on a 4-antenna architecture, but for a terminal, carrier aggregation with 4 antennas is hardly achievable. Contents of the invention [0003] In order to solve existing techni...
