METHOD AND SYSTEM FOR RANDOM ACCESS PROCEDURE AND RADIO LINK FAILURE IN INTER-ENB CARRIER AGGREGATION

摘要

A method and system for configuring a User Equipment (UE) for dual connectivity mode of operation when the UE is carrier aggregated with one or more serving frequencies served by a Master eNB (MeNB) and one or more serving frequencies served by the Secondary eNB (SeNB). The method allows the UE to autonomously initiate the random access procedure on a SCell of the SeNB after adding or replacing SCell of the SeNB. Further, the method allows the UE to handle a Radio Link Failure (RLF) on one or more data radio bearers established between the UE and the SCell of the SeNB.
