Abstract
Embodiments of the present disclosure relate to methods and apparatuses for duplication communication. According to an embodiment of the present disclosure, a method includes: receiving configuration information associated with duplication for data radio bearer (DRB) between a terminate node and a donor node; and in response to the duplication for data radio bearer being activated, transmitting a set of original packets and a set of duplicate packets in up link. Embodiments of the present disclosure solve issues about applying a DRB duplication mechanism in an integrated access and backhaul (IAB) system, which can improve and facilitate the implementation of the IAB system.
