Slot based radio resource management for low latency in LTE-Advanced system

摘要

This paper proposes Slot TTI(transmission time interval) based radio resource management of LTE(Long Term Evolution)-Advanced for low latency. The LTE-A system could not support the new features introduced in 5G system such as low latency. Thus, enhanced Physical Downlink Control Channel (ePDCCH) evolved in LTE-A to fulfill the new requirements for low latency. This paper shows latency reduction by using slotted TTI and ePDCCH in LTE-A system. It is backward compatibility for 5G so that it can reduce radio latency.
