Abstract: An information transmission method for reducing Peak to Average Power Ratio (PAPR), a transmitting terminal and a receiving terminal are provided, to solve the technical problem that it is difficult for a transmitting terminal to reliably transmit side information to a receiving terminal by using conventional methods for reducing PAPR. The method includes: scrambling an initial data block according to a predetermined scrambling mode to obtain a scrambled target data block; determining a scrambling mode index corresponding to the predetermined scrambling mode according to a predetermined relation between scrambling mode indexes and scrambling modes; generating side information carrying the determined scrambling mode index based on the scrambling mode index; and transmitting the side information and the target data block to a receiving terminal.

Abstract: The present disclosure provides a downlink control channel detection method, a downlink control channel transmission method, a network side device and a User Equipment (UE). The downlink control channel detection method includes: determining a detection mode for a downlink control channel; and detecting the downlink control channel in accordance with the determined detection mode for the downlink control channel. The detection mode for the downlink control channel includes a one-stage detection mode in which control information for the detection of a data channel is acquired through a single downlink control channel detection operation and a multiple-stage detection mode in which the control information for the detection of the data channel is acquired through at least two downlink control channel detection operations.
