Method and means for processing information

摘要

The present invention relates to methods and means for processing data frames in a packet data radio system. Data frames (A1, B1-B2) with specified time out periods are submitted to a second protocol layer (PL2) and segmented into radio blocks (Rb) which are transmitted to users (A, B) over a radio link (L). Radio blocks (Rb) not correctly received are re-transmitted. The number of re-transmissions is recorded to calculate the BLER. A transmission time for each data frame (A1, B1-B2) in the second protocol layer (PL2) is estimated. Data frames (A1, B1-B2) with transmission times exceeding a remaining time of their respective time out periods are flushed. The remaining data frames are scheduled to minimise the number of time outs before they are transmitted. The flushed data frames are re-submitted from a first protocol layer (PL1) to the second protocol layer (PL2).
