Abstract
An apparatus and a method for flow control between a Packet Data Convergence Protocol (PDCP) layer and a Radio Link Control (RLC) layer in a communication system are provided. The method includes storing Service Data Units (SDUs) to be transferred to the RLC layer, receiving information on a capacity that is currently unused in a buffer of the RLC layer from the RLC layer, and generating Packet Data Units (PDUs) from SDUs, a capacity of which corresponds to the information, among packets stored in a buffer of the PDCP layer, and then transferring the generated PDUs to the RLC layer.
