Abstract

A method, apparatus and computer program are provided to efficiently and effectively recover from security de-synchronisation. In the context of a method, a size of a Radio Link Control (RLC) Protocol Data Unit (PDU) is determined (30). The method may detect whether the RLC PDU size has changed (32), and, in response to detecting that the RLC PDU size has changed, a RLC RESET procedure is initiated (34). In addition, and also in the context of another method, an uplink transport channel type may be determined to have changed before determining the RLC PDU size and whether it has changed. RLC PDU size may be equal to the transport block size minus the Medium Access Control (MAC) header size.
