Abstract

Certain aspects of the present disclosure relate to techniques for operating a relay having a first plurality of radio bearers (RBs) that interface with a donor base station and having a second plurality of RBs that interface with at least one user equipment (UE). According to certain aspects, the techniques generally include mapping each of the second plurality of RBs to one of the first plurality of RBs based on a QoS class identifier (QCI) associated therewith.
