US 10,476,638 B2 · Operating method and apparatus according to data duplicate retransmission in mobile communication system

Abstract

An operating method and an apparatus according to data duplicate retransmission in a mobile communication system are provided. A method of a User Equipment (UE) according to data duplicate retransmission in a mobile communication system includes storing a Media Access Control Protocol Data Unit (MAC PDU) received from an Evolved Node B (ENB) in a soft buffer, decoding the MAC PDU, determining whether the decoding is a first successful decoding of data of the corresponding soft buffer, and determining whether to forward the decoded MAC PDU to an upper layer according to the determination result.

Dependent claims

A method for operating a terminal in a wireless communication system, the method comprising:

receiving data from a bases station;
determining whether a transmission of the received data is a retransmission based on a new data indicator (NDI);
decoding data;
in case that the data is successfully decoded, determining whether the decoding of the data is a first successful decoding;
and
in case that the decoding of the data is the first successful decoding, delivering the decoded data to a disassembly and demultiplexing entity.
