Information transmission method for reducing papr, transmitting terminal and receiving terminal

An information transmission method for reducing PAPR, applied to a receiving terminal, comprising:

• obtaining side information and a target data block transmitted by a transmitting terminal, wherein the target data block is obtained by the transmitting terminal through scrambling an initial data block according to a predetermined scrambling mode, and the side information carries a scrambling mode index corresponding to the predetermined scrambling mode;
• determining a scrambling mode corresponding to the scrambling mode index carried in the side information according to a predetermined relation between scrambling mode indexes and scrambling modes;
• and
• descrambling the target data block according to the determined scrambling mode to obtain the initial data block.

A transmitting terminal, comprising:

• a scrambling module, configured to scramble an initial data block according to a predetermined scrambling mode to obtain a scrambled target data block;
• a first determination module, configured to determine a scrambling mode index corresponding to the predetermined scrambling mode according to a predetermined relation between scrambling mode indexes and scrambling modes;
• a generation module, configured to generate side information carrying the determined scrambling mode index based on the scrambling mode index;
• and
• a transmitting module, configured to transmit the side information and the target data block to a receiving terminal.

A receiving terminal, comprising:

• an obtaining module, configured to obtain side information and a target data block transmitted by a transmitting terminal, wherein the target data block is obtained by the transmitting terminal through scrambling an initial data block according to a predetermined scrambling mode, and the side information carries a scrambling mode index corresponding to the predetermined scrambling mode;
• a second determination module, configured to determine a scrambling mode corresponding to the scrambling mode index carried in the side information according to a predetermined relation between scrambling mode indexes and scrambling modes;
• and
• a processing module, configured to descramble the target data block according to the determined scrambling mode to obtain the initial data block.
