Methods and communication units are described for power control in a wireless broadcast communication system (200) that comprises a plurality of communication cells, with broadcast content being routed from a base station (226) to at least one wireless communication unit (225, 226) via at least one relay node (RN) (224). A method comprises, at the base station (210), broadcasting the broadcast content from the base station (210) to at least one RN (224); receiving from the at least one RN (224) an indication of signal quality of the broadcast content as received at the at least one RN (224); and adjusting a transmit power level of a broadcast transmission of broadcast content in response to the indication. |
