Method of data block transmitting
First Claim
1. A method of transmitting data in a radio access system, the method comprising:
- generating one or more block sets using a plurality of blocks, wherein the plurality of blocks are divided from an input data;
coding a first block set of the one or more block sets to produce a first coded block set;
transmitting a predetermined number of coded blocks in the first coded block set to a receiver;
receiving a signal indicating a state of a channel environment from the receiver; and
packing an increased or decreased number of coded blocks, as compared to the predetermined number of coded blocks, according to the signal and transmitting the packed coded blocks to the receiver,wherein, if the signal indicates that the channel environment is better than a predetermined threshold, a second block set of the one or more block sets is coded to produce a second coded block set, a coded block is borrowed from the second coded block set, and the increased number of coded blocks are packed and transmitted to the receiver, andwherein random coefficients used for coding the first block set and the second block set are identical to each other.

Abstract
A method of transmitting data to guarantee reliability and, more particularly, a method of efficiently transmitting data by adjusting the size of data blocks according to a channel environment are provided. The method includes dividing input data into a plurality of blocks and generating one or more block sets using the plurality of blocks, coding a first block set of the one or more block sets and transmitting a predetermined number of coded blocks in the first coded block set to a receiver, receiving a signal indicating the state of a channel environment from the receiver, and packing a more increased or decreased number of coded blocks than the predetermined number of coded blocks according to the signal and transmitting the coded blocks to the receiver. By this configuration, it is possible to efficiently adjust a block error rate by adaptively increasing or decreasing the size of blocks according to the channel environment.

9. A method of transmitting data in a radio access system, the method comprising:
-
generating one or more block sets using a plurality of blocks, wherein the plurality of blocks are divided from an input data; coding a first block set of the one or more block sets to produce a second coded block set; transmitting a predetermined number of coded blocks in the first coded block set to a receiver; receiving a signal indicating a state of a channel environment from the receiver; and packing an increased or decreased number of coded blocks, as compared to the predetermined number of coded blocks, according to the signal and transmitting the packed coded blocks to the receiver, wherein, if the signal indicates that the channel environment is better than a predetermined threshold, the increased number of coded blocks are selected from the first coded block set and are packed and transmitted, and wherein a random coefficient used for coding the increased number of coded blocks is mutually independent from a random coefficient used for coding the predetermined number of coded blocks.
