Apparatus and method for generating MAC protocol data unit in wireless communication system

摘要

An apparatus and a method for transmitting an Automatic Repeat reQuest (ARQ) block in a wireless communication system are provided. The method for transmitting the ARQ block includes when transmitting the ARQ block to a receiving stage in a Not Sent state, transitioning to an Outstanding state to wait to receive one of an ACK and a NACK for the ARQ block, when receiving the NACK for the ARQ block from the receiving stage in the Outstanding state, transitioning to a Waiting for Retransmission state, when determining to retransmit the ARQ block for the NACK by splitting the ARQ block into at least two ARQ sub-blocks in the Waiting for Retransmission state, transitioning to a Rearrangement state, retransmitting the ARQ block for the NACK by splitting the ARQ block into at least two ARQ sub-blocks in the Rearrangement state, and when receiving an ACK for every ARQ sub-block having the same ARQ Sequence Number (SN) in the Rearrangement state, transitioning to a Done state and finishing transmission of the ARQ block having the ARQ SN.

1. A method for transmitting an Automatic Repeat reQuest (ARQ) block in a transmitter of a wireless communication system, the method comprising:
preparing for the ARQ block retransmission; determining whether to retransmit the ARQ block without rearrangement or to retransmit the ARQ block with rearrangement; if determined to retransmit the ARQ block with rearrangement, fragmenting the ARQ block into ARQ sub-blocks, each of which is assigned to a sub-block sequence number sequentially, retransmitting the ARQ sub-blocks, waiting for ARQ feedback of the ARQ block or of all ARQ sub-blocks of the ARQ block, and if a positive acknowledgement arrives regarding the ARQ block, transitioning to a done state.
