Abstract
The present disclosure relates to a 5G (5th generation) or pre-5G communication system for supporting a higher data transmission rate than a 4G (4th generation) communication system such as Long Term Evolution (LTE). In accordance with various embodiments of the present disclosure, a device in a Central Unit (CU) connected to a Distributed Unit (DU) and a fronthaul in a wireless communication system may comprise: a communication interface for performing signaling between the CU and the DU; and at least one processor for determining whether to control a congestion state of the DU on the basis of the signaling, and when controlling the congestion state of the DU, stopping transmission of at least one packet to the DU before processing a Packet Data Convergence Protocol (PDCP).
