Data Transmission Method in Communication System

Abstract

The present disclosure provides a data transmission method in communication system. A data transmission method for a transmitter includes: performing (S111) an initial transmission of the data with a first redundancy version, on radio resources corresponding to a configured scheduling; and without receiving an acknowledge response from a receiver, performing (S112) a retransmission of the data with a second redundancy version, on radio resources corresponding to the configured scheduling. Accordingly, a data transmission method for a receiver includes: receiving (S121) a retransmission of the data with a second redundancy version, on radio resources corresponding to a configured scheduling, from a transmitter. The retransmission corresponds to an initial transmission of the data with a first redundancy version, on radio resources corresponding to the configured scheduling.
