Problems solved by technology

It can be seen that the biggest problem in realizing carrier aggregation in the low, middle and high frequency bands is that the antenna design is very difficult, and the passive efficiency of the antenna is very low, which cannot meet the test requirements at all.

Abstract

The invention discloses a carrier aggregation method and a terminal. The carrier aggregation method comprises the steps of: aggregating low-frequency carriers and intermediate-frequency carriers into low-intermediate-frequency carriers by means of a diplexer; when the terminal is in a single carrier working mode, opening a port of the low-intermediate-frequency carriers or a port of high-frequency carriers by means of a switch to control the low-intermediate-frequency carriers or the high-frequency carriers to operate; and when the terminal is in a multiple-carrier operating mode, synchronously opening the port of low-intermediate-frequency carriers and the port of high-frequency carriers by means of the switch to control the low-intermediate-frequency carriers and the high-frequency carriers to operate synchronously.

Description

technical field [0001] The present invention relates to carrier aggregation technology, in particular to a carrier aggregation method and a terminal. Background technique [0002] During the evolution process from Long Term Evolution (LTE, Long Term Evolution) to LTE Advanced (LTE-Advanced), wider spectrum requirements are an important factor affecting the evolution. For this reason, the 3rd Generation Partnership Project (3GPP, the 3rd Generation The Partnership Project) standard proposes a carrier aggregation (CarrierAggregation) technology. Simply put, carrier aggregation can aggregate multiple carriers into a wider spectrum, and at the same time aggregate some discontinuous spectrum fragments together, which can maximize the use of existing LTE equipment and spectrum resources. Thanks to the wider spectrum, the most intuitive benefit after carrier aggregation is a substantial increase in transmission speed. [0003] At first, the LTE terminal project only required dual...
