Abstract:
1. A method for transmitting data in a wireless communication system, the method comprising: dividing an input bit stream into segments; adding error detection code into each segment of the divided input bit stream in order to generate a data unit; dividing the generated data unit into a plurality of blocks with a fixed size; coding each of the plurality of blocks using a random linear coding in order to generate coded block bits, wherein a number of the generated coded block bits is determined by at least one parameter related to a given Galois field, and wherein each coded block bit in a coded block is rearranged into different classes according to a bit error probability on a position of the coded block; mapping the coded block bits to a plurality of modulated symbols; transmitting the plurality of modulated symbols; receiving a transmission request for one or more additional coded blocks including additional coded block bits mapped to one or more additional modulated symbols; and transmitting the one or more additional modulated symbols, wherein the one or more additional coded blocks are coded using coefficient values that are different from coefficient values used in a previous transmission.
