Summary:A method of performing resource allocation in OFDM transmission is disclosed. The method includes performing a partitioning of the OFDM spectrum into a number of predefined regions (Rij, R′ij) of sub-carriers (SCi) for a number of OFDM transmission cells, assigning at least one respective transmission-related characteristic to the regions of sub-carriers, and allocating the resources for communication with at least one user equipment in at least one region of sub-carriers based on the partitioning and dependent on the characteristic assigned to the regions of sub-carriers. This allows fast resource allocation with low signaling effort, as well as fast adjustment to changing system settings or changing systems conditions, while providing a possible alternative to costly handover procedures.
