Abstract: When a terminal aggregates three downlink carriers by using the carrier aggregation (CA) of the LTE-A technology and transmits an uplink signal on two uplink carriers while aggregating two uplink carriers, a harmonic component and an intermodulation distortion (IMD) component are generated, thereby influencing a downlink band of the terminal itself. Therefore, the present specification presents a scheme therefor.

Abstract translation: 当终端通过使用LTE-A技术的载波聚合（CA）来聚合三个下行链路载波并且在聚合两个上行链路载波的同时在两个上行链路载波上发送上行链路信号时，产生谐波分量和互调失真（IMD）分量， 从而影响终端自身的下行链路频带。 因此，本说明书给出了一种方案。
