摘要： Real-time media or multimedia services in 3GPP GSM/EDGE-compliant mobile radio networks call for reducing the actual latency of transmissions. Resources are assigned by the network to set up or reconfigure a TBF associated to the uplink/downlink transmission of radio blocks from/to an MS. A 5-bit 'Coding' field is configured in the header of the involved RLC/MAC messages to select the transmitting/receiving window size. An additional signalling bit, also called scaling bit, is asserted/negated according to two opportunities offered by the new MAC protocol to properly select the window size. Thanks to the introduction of the scaling bit a subdivision of the time windows for type of services is made possible. Non real-time services, e.g. file transfer, avail of standard window sizes for MSs with multistat capability, as reported in 3GPP TS 44.060, V7.3.0 (2006-01 ), Release 7, subclause 9.1.9, for EGPRS TBFs. Delay-sensitive services, e.g. media or multimedia real-time transmissions, avail of new window sizes with scaled down values remapped to start from 1 to (maximum) 64 RLC/MAC blocks. The scaling bit is asserted or negated by BSC accordingly. Both peer entities comprised in a TBF are receiving the RLC/MAC messages with the proper setting of the scaling bit and the 5-bit coding IF; these entities decode the scaling bit and behave accordingly. The behaviour consists of either assuming the standard window size or scaled window size addressed by the same predetermined 5-bit 'coding' information element.

摘要： 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 (FIG: 12).

摘要： A mobile station operating in EGPRS mode needs to the early establishment of an uplink TBF although has not data to send, at the only precautionary purpose of preventing an intolerable latency negatively affecting the subsequent delay-sensitive transmissions. To this aim, the mobile sends a Packet Channel Request message in one phase access mode including a new establishment cause called "Early TBF establishment". The network establishes an uplink TBF indicating the requester and assigns a radio resource on one PDCH channel or more. Then the network schedules the transmission from the mobile station also when it does not have data to transmit other than dummy packets. This is performed through the USF flags in the usual manner. As soon as actual data become available for transmission, the mobile send them instead of dummy packets. In an alternative embodiment the mobile sends the Packet Channel Request message in two phase access mode. As soon as the Packet Uplink Assignment message is received by the mobile station, it send a Packet resource Request message including an Extended Uplink TBF information. The network behaves as in the previous case (fig.3).
