Abstract
The invention concerns an improvement to the most recent proposals about a fast ARQ mechanism to be operated soon inside 3GPP GERAN mobile radio systems. The fast ARQ avails of short bitmaps spanning only few octets piggybacked in the payload of the RLC/MAC block which conveys the relevant ACK/NACK signalling. The main improvement is that to shift the short bitmap from payload data to the header of the same RLC/MAC block transmitted either in uplink or downlink direction indifferently. This allows the short bitmap to be encoded together with the header taking advantage of the same coding which is noticeably more robust than the one used for payload. Synchronization between transmitting and receiving frames are requested in reporting with short bitmaps. The correct retransmission of badly received radio blocks needs the knowledge of the fixed delay (expressed as a number of RLC/MAC block periods) between the instant of transmission of a radio block and the instant of reception of the short bitmap. A second improvement is to allocate the short bitmap in a new zone placed immediately after the header of the RLC/MAC blocks and encode it independently of the payload using a more robust coding against the errors than the robustness of the MCS used in the payload data part.
