Abstract: Provided are a method and an apparatus for transmitting data in a wireless communication system. Logical channels or data streams are divided into two groups according to Qos characteristics and sorted in ascending order of the target MCS. The logical channels or data streams arranged in ascending order of the target MCS are transmitted through a plurality of shared channels scheduled by one DCI. The MCSs of the two groups are one of a first type MCS index indicating both modulation order information and code rate information and a second type MCS index indicating modulation order information, and are limited to the same type of MCS indexes.

Abstract: Provided is a method performed by a user equipment (UE) in a wireless communication system including receiving a downlink signal, filtering the downlink signal, sampling the filtered downlink signal, performing differential decoding on the sampled downlink signal, obtaining a primary synchronization signal (PSS) sequence based on the downlink signal on which the differential decoding is performed, and obtaining cell area information based on the PSS sequence obtained based on the downlink signal on which the differential decoding is performed.

Abstract: The present disclosure provides a method and device for performing low-latency and high-speed transmission in a wireless communication system. The present disclosure also provides a method and device for performing efficient HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement) feedback and retransmission for recovering a transmission error occurring in a wireless communication system. The present disclosure also provides a method and device for reducing transmission latency by reducing HARQ retransmission probability using an erasure code, and for reducing radio resources and the number of HARQ-ACK feedback bits and DCI bits required for retransmission when retransmission is unavoidably necessary.
