A network node () of a wireless telecommunication network () uses a first coding scheme (selected from plural possible coding schemes) for encoding of a point-to-multipoint (PTM) transmission carried to plural mobile stations () on a common downlink channel (). The mobile stations () receiving the point-to-multipoint transmission on the common downlink channel () evaluate the link quality of the point-to-multipoint transmission. Feedback from the plural mobile stations () regarding the link quality of the point-to-multipoint transmission is provided to the network node () on a common uplink channel (). A controller () at the network node () monitors information received on the common uplink channel for feedback regarding the link quality of the point-to-multipoint transmission. The controller () at the network node () uses the feedback to determine whether to change from the first coding scheme to a second coding scheme for the encoding of the point-to-multipoint transmission to the plural mobile stations ().
