Abstract
Provided is a method of synchronizing a frame using a cycle prefix (CP) in a mobile multi-hop relay (MMR) network. The frame is synchronized using the CP of the frame after obtaining a frame synchronization using a preamble of the frame, which does not need an additional preamble, so that a preamble necessary for the frame synchronization is transmitted to a subordinate station during a preamble receiving section.
Claims5
A method of synchronizing a frame of a relay station in a mobile communication network, the method comprising:
- transmitting a preamble to a subordinate station;
- and
- correcting a frame synchronization using cycle prefixes (CPs) in OFDM symbols of a frame received from a parent station.
Dependencies are inferred from the claim text.
