Abstract: To meet different latency requirements a solution for a system having one or more apparatuses using a first type of relaying or a second type of relaying, the first type requiring more processing time at an apparatus than the second type, is disclosed. In the solution a type of relaying for a child apparatus is determined at least based on one or more of a latency requirement and feedback information on channel; and transmissions to or from child apparatuses are scheduled at least according to a determined type of relaying, wherein transmissions using the first type of relaying are scheduled to take place in the time domain of a transmission slot after transmissions using the second type of relaying; and transmissions to or from the child apparatus are processed according to the determined type of relaying.
