SCRAMBLED TRANSMISSION METHOD AND DEVICE THEREOF

摘要

Disclosed are a scrambling transmission method and device thereof. The method comprises: a user terminal generates the message to be sent and modulates the message to be sent to generate the data modulation symbols; the user terminal scrambles the data modulation symbol using the cell-specific scrambling sequence, to generate the scrambled data modulation symbols; and the user terminal sending the scrambled data modulation symbols via a DFT-S-OFDM transmission structure with a time domain spreading. The present invention can reduce the interference among different user terminal data on the same resource in adjacent cells, thus improve the detection performance of uplink control signals.
