Abstract: The invention relates to a mobile communication system. The mobile communication system includes a first base station configured to transmit at least part of a first data set of data segments arranged in a first sequence to a user terminal, and a second base station configured to transmit at least part of the first data set of data segments arranged in a second sequence to the user terminal, the second sequence of the first data set being an inverse of the first sequence of the first data set. The invention also relates to a coordination component, base station and user terminal for use in this system and to a method of arranging data segments in sequences performed by the coordination component. The invention further relates to a method of transmitting an acknowledgement, performed by the base station or by the user terminal.

Abstract: The disclosure relates to a transmission node and method for multicasting a plurality of original data packets to a plurality of receivers in a cell of a cellular communications system. The method comprises the step of multicasting a set of original data packets and a single network coded data packet associated with the set of original data packets to the plurality of receivers in the cell. The set of original data packets consists of a number of original data packets of the plurality of original data packets and the number of original data packets in the set of original data packets is dependent on a multicast data packet loss probability for transmitting data packets to one or more of the plurality of receivers in the cell. The single network coded data packet is a linear combination of two or more original data packets in the set of original data packets.
