摘要： The invention relates to management of data packets and buffers comprising segments of data packets in a mobile communication system (1). Information associated with data packet segments is analyzed by a Base Station System (BSS) (100) housing a data buffer (120). Based on this information analysis, the BSS (100) can identify those segments (P(FIRST) - P(LAST)) in the buffer (120) that constitutes a complete data packet. Once identified, the segments can be discarded from the buffer (120). The information can include size information (S(k), S(k+1)), whereby the analysis comprises pairwise comparing the size (S(k)) of a current segment (P(k)) with the size (S(k+l)) of a next consecutive segment (P(k+l)). This size comparison enables identification of a first segment (P(FIRST)) and a last segment (P(LAST)) of the complete data packet. The information could also, or alternatively, include a notification provided in the header of the segment. This notification identifies the associated segment as the first or last segment of the data packet or an intermediate segment.

摘要： A method, scheduler and a network node for scheduling retransmissions in a telecommunications system is described. The method comprises determining a scheduling point of time for a retransmission in a periodic interval cycle for transmissions in the network node, which point of time in the cycle is different as compared to the point of time in the cycle when the previous transmission was performed. The retransmission is then scheduled to be performed at that different point of time in the cycle, hence providing the placing of the data in a different position in the frame as compared to the data position of a previously interfered transmission of that data. This provides the advantage of providing an increased probability of avoiding that retransmitted data is again interfered in transmissions suffering from periodic interference problems.

摘要： A method of controlling a data unit relay device is described, applied to a relay ARQ protocol in accordance with which a source peer sends data units to a destination peer via at least one relay peer. The relay ARQ protocol provides for a first type and second type of receipt information, where the first type is indicative of a correct receipt at a relay peer, and the second type is indicative of a correct receipt at the destination peer. In a data unit relay device that is arranged for deliberately dropping data units of the relay ARQ protocol under one or more predetermined conditions, a procedure is provided for indicating to the source peer and the destination peer that a data unit has been deliberately dropped and for identifying the deliberately dropped data unit, such that the source and destination peer may perform retranmission control for the dropped data unit as if it had been successfully received at the destination peer.
