摘要
介绍了链路层用于差错控制的常用技术———前向纠错编码 (FEC)和自动重传请求 (ARQ)结合的技术 ,即混合ARQ。主要介绍HARQ的 3种基本类型 (编码方案 )和ARQ的 3个标准重传协议 ,最后简要给出了 3GPPHARQ的两种应用方式。
The most common techniques for the error control at the Layer 2 based on the Automatic Repeat request (ARQ) techniques used in combination with the Forward Error Correction (FEC) coding are described. Three basic HARQ types and three popular ARQ retransmission schemes are introduced. Two application modes of HARQ, on based on RLC and the other based on L1, are presented.
