Abstract: Embodiments of the present invention provide a method and a device for reducing intermodulation interference. The method includes: performing real-time estimation according to time domain information of M downlink transmit signals, to obtain a first intermodulation interference signal; and cancelling, according to the first intermodulation interference signal, intermodulation interference generated by the M downlink transmit signals in an uplink receive signal, where M is an integer greater than or equal to 2, and the M downlink transmit signals are baseband signals that are transmitted on M carriers and that are not combined. Based on the foregoing solutions, the actually generated intermodulation interference can be effectively cancelled, thereby reducing intermodulation interference and improving system performance.

Abstract: The present disclosure relates to a method and an apparatus for sending and receiving a downlink data block of a packet data service. A network side adds indication information of downlink data modulation modes to a downlink data block, where the downlink data block includes first information and second information; the network performs symbol mapping processing on the first information by using a first modulation mode to obtain a first modulated signal; the network performs symbol mapping processing and data pre-processing on the second information by using a second modulation mode to obtain a second modulated signal; the network combines these two modulated signals to obtain an aggregate modulated signal; and the network sends the aggregate modulated signal. With the present disclosure, throughput of downlink data is increased while a USF compatibility between more types of low-capability mobile terminals is considered.
