TRANSMITTER AND RECEIVER DEVICES PERFORMING REPETITION BEFORE INTERLEAVING AND PUNCTURING AFTER INTERLEAVING AND METHODS THEREOF

摘要

The present invention relates to transmitter and receiving devices for wireless communication. The transmitter device comprises a transceiver (25) configured to: receive at least one stream of information bits; and further comprises a processor (30) configured to: encode said at least one stream of information bits by using at least one error correction code to obtain at least one mother code word having a mother code rate R M ; and if the mother code rate R M is smaller than a transmission code rate R Tx , interleave said at least one mother code word to obtain an interleaved code word, and rate match said interleaved code word, to obtain a shortened code word having a code rate that is higher than the mother code rate R M , if the mother code rate R M is not smaller than a transmission code rate R Tx associated with said at least one mother code word rate match said at least one mother code word to obtain an extended code word, and interleave said extended code word, having a code rate that is lower than the mother code rate R M ; modulate said shortened or extended code word to obtain modulated symbols; wherein said transceiver (25) is further configured to transmit a signal comprising said modulated symbols over a radio channel of the wireless communication system (10). Furthermore, the present invention also relates to corresponding methods, a computer program, and a computer program product.
