Problems solved by technology

At present, the existing technologies for terminal carrier aggregation in the industry are generally a combination of low-band (Low Band) and high-band (High Band), which can realize Intra-CA (Intra-CA). For low-, medium-, and high-band carriers Aggregation At present, the existing solutions are all based on the 4-antenna architecture. However, for the terminal, the 4-antenna carrier aggregation is hardly achievable.

Abstract

The invention discloses a carrier aggregation device, which comprises: a first transceiver antenna, a second transceiver antenna, a first radio frequency front end, a second radio frequency front end and a radio frequency transceiver chip; wherein, the signal received by the first transceiver antenna passes through The first RF front-end is divided into one high-frequency signal, one intermediate-frequency signal, and one low-frequency signal, and then enters the RF transceiver chip; the signal received by the second transceiver antenna is divided into one high-frequency signal, one intermediate-frequency signal, and one low-frequency signal through the second RF front-end After the signal, enter the RF transceiver 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 the case of , 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 (Low Band) and high-band (High Band), which can realize Intra-CA (Intra-CA). For low-, medium-, and high-band carriers Currently, existing solutions for aggregation are all based on a 4-antenna architecture. However, for terminals, carrier aggregation with 4 antennas is hardly achievable. Contents of the invent...
