Abstract: Embodiments methods implemented with a server or a processor of a mobile communication device (e.g., a multi-standby communication device) reduce the redundancy information needed to achieve adequate reception service on a first radio access technology (RAT) sharing an RF resource with a second RAT. The device processor may implement at least one tune-away management strategy that mitigates the amount of data for the first RAT that is lost during the tune-away event. Thus, by implementing the one or more tune-away management strategies, the device processor may ensure that less redundancy information overhead is needed to correct or replace lost or partially received data, improving latency, channel usage, and the first RAT's overall reception performance. In some embodiments, a server may implement one or more strategies for including redundancy information into data that is sent to a first RAT to mitigate the negative effects of tune aways on the first RAT.
