METHOD AND DEVICE FOR RELIABLE TRANSMISSION OF RADIOUNITS WITH COMBINED ACK/NACK FIELDS Russian patent published in 2012 - IPC H04B7/24 H04L1/16 

FIELD: information technology.

SUBSTANCE: method to be used in wireless transmission/receive units (WTRU) designed for wireless communication data transmission including bits of piggyback acknowledgement/non-acknowledgement (PAN) comprises steps in which bit stream for transmission is prepared, where the bit stream contains data bits and PAN bits, the bit stream is interleaved to create interleaved bit stream, the interleaved bit stream is modulated to create character set where each character represents bit set and has position of list significant bit (LSB), where no PAN bits present in LSB position of each one from this character set, this character set is transmitted. Thus, PAN bits in unreliable bit positions of modulated character are transposed with data bits located in more reliable bit positions. In this process, to characters containing PAN bits power offset to transmission power corresponding to each bit of bit stream can be applied.

EFFECT: higher data transmission rate and transmission capacity of communication system.
