摘要： Data is received that has been transmitted via a combination of radio frequency signals using carrier aggregation, each radio frequency signal occupying a respective radio frequency band, the bands being arranged in two groups separated in frequency by a first frequency region, the first of the two groups occupying a wider frequency region than the second group. Embodiments provide a method and apparatus for downcoverting the radio frequency signals using quadrature mixing to give inphase and quadrature components, and the inphase and quadrature components are filtered using a first bandpass filter bandwidth to give first bandpass filtered inphase and quadrature components and filtered using a second bandpass filter bandwidth, different from the first bandpass filter bandwidth, to give second bandpass filtered inphase and quadrature components.
摘要翻译：接收已经通过使用载波聚合的射频信号的组合发送的数据，每个射频信号占据相应的无线电频带，频带被布置成两组，频率分为第一频率区域，第一个频率区域占据比第二组更宽的频率区域的组。实施例提供了一种用于使用正交混合来降频射频信号以给出同相和正交分量的方法和装置，并且使用第一带通滤波器带宽对同相和正交分量进行滤波，以给出第一带通滤波的同相和正交分量，并使用第二带通滤波器带宽，不同于第一带通滤波器带宽，给出第二带通滤波同相和正交分量。

摘要： A receiver uses a local oscillator to receive data transmitted via a combination of radio frequency signals using carrier aggregation. Each radio frequency signal occupies a respective radio frequency band and the radio frequency hands are arranged in two groups, a first group and a second group, separated in frequency by a first frequency region, each of the groups including one or more radio frequency bands and the first group occupying a wider frequency region than the second group. The radio frequency signals are processed using the local oscillator by setting the local oscillator, during the processing, to a frequency that is offset from the centre of a band defined by outer edges of the frequency regions occupied by the two groups.
