Title:ExploringTDD-LTEFrameOffsetIssuesLeadingtoRRCAccessFailure
Abstract:
Withtherapidadvancementofwirelesscommunicationtechnologies,LTE(Long-TermEvolution)hasemergedasthedominantcellularnetworktechnologyworldwide.TDD-LTE(Time-DivisionDuplexLong-TermEvolution)isoneoftheduplexingmodesusedinLTEsystems,whichallowsbothuplinkanddownlinktransmissionstosharethesamefrequencybandbutoperateindifferenttimeslots.However,TDD-LTEcomeswithitsownsetofchallenges,suchasframeoffsetissuesthatcanleadtoRRC(RadioResourceControl)accessfailures.Thispaperaimstoexplorethecauses,impacts,andpotentialsolutionstoTDD-LTEframeoffsetissuesandtheirimpactonRRCaccessfailures.
