Patent ID: 8619896

Claim:
A system for transmitting information bits, comprising a terminal and a base station in communication with the terminal, wherein the terminal comprises a processor and a transmitter: the processor is configured to divide information bits to be transmitted into at least two groups, encode the information bits to be transmitted in each group to obtain at least two groups of coded bits, combine the at least two groups of coded bits to obtain a total coded bits sequence, wherein the total coded bit sequence is obtained by dividing the coded bits in each group into N sub-groups according to a predetermined modulation scheme, wherein N is an integer greater than 1, and reordering the sub-groups of the coded bits in each group, and the sub-groups in at least one group of the coded bits are discontinuously distributed in the total coded bits sequence after reordering; the processor is configured to modulate the total coded bits sequence to obtain modulation symbols, wherein each modulation symbol is obtained by the modulation of the coded bits in the same group; the transmitter is configured to transmit the modulation symbols to the base station; and the base station comprises a receiver and a processor: the base station receiver is configured to receive the modulation symbols transmitted by the terminal; and the base station processor is configured to demodulate and decode the modulation symbols to obtain the information bits to be transmitted, wherein the predetermined modulation scheme comprises: in instances where the predetermined modulation scheme is Quaternary Phase Shift Keying (QPSK) modulation, every two coded bits constitute each of the N sub-groups; and in instances where the predetermined modulation scheme is 16-Quadrature Amplitude Modulation (16QAM), every four coded bits constitute each of the N sub-groups.
