ABSTRACT:
A method is disclosed for receiving a downlink radio link control (RLC) data block with a mobile station, as is a mobile station and a computer program that operate in accordance with the method. The method includes receiving the RLC data block; determining if a final block indicator (FBI) bit is set and, if it is, determining if a Relative Reserved Block Period (RRBP) field is valid, and, if it is not, discarding the received data block. For the case where the mobile station is in an EGPRS TBF mode of operation, and if a retransmitted RLC data block is split into two parts, and if in a first part of the retransmitted RLC data block the FBI is set, and in a second retransmitted part of the RLC data block there is a valid RRBP field, then these data blocks are retained.
