This TR is related to the study item "Further advancements for E-UTRA". It describes relay architectures being discussed for E-UTRA (LTE-Advanced).
The following two architectures have been identified for supporting relays in LTE:
  • Architecture A, with following variants:
    • Alt 1: Full-L3 relay, transparent for DeNB;
    • Alt 2: Proxy S1/X2;
    • Alt 3: RN bearers terminate in DeNB;
  • Architecture B, with following variant:
    • Alt 4: S1 UP terminated in DeNB.
We follow the above grouping of architectures and alternatives when describing the different solutions throughout this document. Although not a prioritized scenario, it is assumed that all alternatives in principle support multi-hop RN deployments. RN mobility is also not considered a prioritized scenario.
