Abstract
Apparatus and method are provided to enhance scheduling request to multiple schedulers with inter base station carrier aggregation. In one novel aspect, the UE monitors and detects one or more SR triggering event. The UE selects one or more base stations based on predefined criteria and sends the SR to the selected one or more base stations. In one embodiment, at least one radio bearer of the UE is associated with multiple cell groups (CGs) in different base stations with association priorities. The association priorities may be configured by the network, derived based on predefined UE configurations, derived from load information received by the UE, or derived from radio measurements. In one novel aspect, the UE upon detecting SR failure triggered on a triggering radio bearer, sends SR failure indication to a RRC layer or associates the triggering radio bearer with a different base station.
