Abstract: Systems, methods, apparatuses, and computer program products for reporting of feasibility of activated transmission configuration indicator/transmission coordination indication (TCI) states. For example, a user equipment (UE) may determine whether one or more measurements satisfy one or more thresholds for one or more TCI states, and may transmit an indication of whether the one or more measurements satisfy the one or more thresholds. The UE may then deactivate at least one of the one or more activated TCI states, or may activate one or more additional TCI states, based on the indication, and may use one or more of the activated TCI states for a downlink (DL) or uplink (UL) transmission.

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.
