  • Carrier Aggregation is one of these new techniques. Unlike a typical communication system using an uplink as a signal carrier in uplink and downlink transmissions between a User Equipment (UE) and an eNB, carrier aggregation makes it possible to combine a primary carrier and at least one secondary carrier in order to increase a transmission/reception data transmission rate in proportion to a number of aggregated carriers.
  • a cell operating on the primary carrier is referred to as a primary cell (or may also be referred to as a PCell or a first cell), and a cell operating on a secondary carrier is referred to as a secondary cell (or may also be referred to as an SCell or second cell).

  • Exemplary embodiments of present invention provide a method for handling a random access problem and/or failure arising in a random access procedure for acquiring uplink timings configured in association with carrier aggregation according to whether the random access procedure is for a Primary Cell (PCell) or a Secondary Cell (SCell). If a random access problem and/or failure has arose in the PCell, a Medium Access Control (MAC) layer entity notifies a Radio Resource Control (RRC) entity of the random access problem and/or failure in a User Equipment (UE) which has detected the problem and/or failure.
  • PCell Primary Cell
  • SCell Secondary Cell
  • RRC Radio Resource Control
  • the RRC entity performs an RRC Connection Re-establishment, and the corresponding RRC Connection Reconfiguration operation, in order to re-establish a connection with an enhanced Node B (eNB). If the connection reestablishment is successful, then the RRC entity reconfigures a Signaling Radio Bearer and a Data Radio Bearer and restarts Ciphering/Integrity protection check. Otherwise, if the random access problem and/or failure has arisen in the SCell, the MAC layer entity of the UE, which has detected the problem and/or failure, suspends the random access procedure. In this case, the MAC layer entity does not notify the RRC layer entity of the random access problem and/or failure that arose in the SCell.
  • eNB enhanced Node B
  • the random access control method of a UE in a mobile communication system configured with a primary cell and at least one secondary cell includes attempting random access through the primary and second cells, detecting a failure of the random access, determining whether the random access failure has arose in the primary cell or the secondary cell, and determining whether to continue the random access procedure according to whether the random access failure arose in the primary cell or the secondary cell.
