Abstract

In a telecommunications network including a mobile terminal in communication with a network base station, and at least one relay node that assists the base station with downlink data transmissions towards the mobile terminal, a method is provided of enabling coherent demodulation of a scheduled data block transmitted in the downlink by the base station and the at least one relay node. A reference signal is provided in the scheduled data block which is configured to change the mobile terminal from using cell specific reference signalling to using mobile terminal specific reference signalling to enable the mobile terminal to demodulate the scheduled data block transmitted in the downlink by the at least one relay node and the base station. Further, a method of performing synchronous retransmission of data includes transmitting pre-scheduling information for any required synchronous retransmission of a first data transmission by the relay node and the transmitting entity.
