Implementation and Performance Analysis of HARQ in 3GPP LTE System Level Simulation

摘要

The standardization of 3GPP LTE/ LTE-A is in process and related research is also very popular. However, when CoMP has been raised in 3GPP #bis S3 meeting, implementation of CoMP HARQ in LTE system level simulation is in silence. In this paper, we design a data structure of HARQ model in our Matlab-based LTE System Level simulator, which is standardized in 3GPP. This data structure is an easy-upgraded one that can fully upgrade to Coordinated Muiti Point (CoMP) mode in the future. A performance analysis is also given to make a comparison of Chase-Combine (CC) and Incremental Redundancy (IR).
