Limiting HARQ Retransmissions in Downlink for Poor Radio Link in LTE
HARQ is a stop and wait protocol supporting soft combination of retransmitted data which is used for facilitating fast error detection and correction. In Long term Evolution (LTE), HARQ is implemented by MAC level module called HARQ entity. The justification of HARQ retransmissions lies in recovering data correctly, though they consume radio resources. In this paper, it is proposed that the maximum number of HARQ retransmissions in downlink may be limited in order to save radio resources for UEs with poor radio link in LTE. Adequate simulation results with LTE link level simulator strengthen the basis of this proposal.
