Mechanism Research and Algorithm Improvement of ARQ in LTE
Chen Fatan · Video Engineering · 2013
The ARQ mechanism in LTE is researched in this paper,and as the problem of resource waste in ARQ acknowledge algorithm which just adds lost PDUs' SN or segment information when assembling status report,a kind of adaptive acknowledge algorithm is put forward. By setting different reference parameters and adopting different offset algorithm,the confirmation efficiency and resource utilization are effectively improved,and the system achieves high throughput.
