1. A method of a central unit (CU), comprising:
receiving, from a terminal, measurement information for radio access points;
configuring a cluster using two or more radio access points among the radio access points based on the measurement information;
generating first data to which a cluster header including a cluster identifier of the cluster is attached; and
transmitting the first data to the two or more radio access points,
wherein second data generated in the two or more radio access points includes the first data and a packet data convergence protocol (PDCP) header, the CU performs a first partial PDCP function, the two or more radio access points perform a second partial PDCP function, and the cluster header includes at least one of information on a number of PDCP service data units (SDUs), a duplicate transmission tag, or information on a length of the SDU.
