CARRIER AGGREGATION
First Claim
1. Method for carrier aggregation of at least two Orthogonal Frequency Division Multiplexing (OFDM) carriers in a radio communication system, each of said at least two OFDM carriers comprising subcarriers being spaced in accordance with a subcarrier spacing of said radio communication system, respectively, comprising:
- allocating frequencies in a spectrum, such that the subcarriers of said at least two OFDM carriers are located separated from each other by a multiple of said subcarrier spacing, andsynchronizing transmission on said at least two OFDM carriers in time, whereinat least one of said at least two OFDM carriers is an extended legacy carrier being compatible with a legacy radio communication system, said extended legacy carrier comprising a legacy carrier of said legacy radio communication system.
