Abstract:
A method and apparatus for circular buffer-based rate matching and burst multiplexing for data transmission. According to the method and apparatus, rate matching patterns are efficiently determined according to data code rates in a wireless communication system using CBRM, and burst multiplexing is performed in units of bits without using an external channel interleaver when several RLC data blocks are transmitted via radio blocks. Accordingly, data bits are distributed into and carried by a plurality of bursts, thereby improving transmission performance.
