Abstract
A packet buffering apparatus and method in a multi-hop relay system supporting hop-by-hop retransmission are provided. In the buffering apparatus and method, a first buffer buffers a user packet until the user packet is successfully transmitted to a next node, and a second buffer buffers the user packet until the user packet is successfully transmitted to an MS, after the user packet is successfully transmitted to the next node. Accordingly, time delays and transmission costs are reduced.
