Claim:
1. A method of relaying data in a wireless network comprising a relay node configured for transmissions on a basis of a radio frame with a plurality of subframes, the method comprising: the relay node receiving, in a first subframe of the plurality of subframes, first unicast transmission signals, wherein the plurality of subframes comprises subframes configured as subframes for multicast transmission, of which some are used for unicast transmissions; the relay node decoding the first unicast transmission signals to obtain unicast data; the relay node forwarding the decoded unicast data by sending second unicast transmission signals in a second subframe of the plurality of subframes; the relay node receiving control data from a base station; the relay node determining, responsive to the received control data, that the base station uses a third subframe of the plurality of subframes for a multicast transmission and not for a unicast transmission; and in response to determining that the base station uses the third subframe for a multicast transmission and not for a unicast transmission, the relay node receiving, in the third subframe, multicast transmission signals from the base station, amplifying the multicast transmission signals, and synchronously with the multicast transmission signals from the base station, sending the amplified multicast transmission signals in the third subframe.
