摘要： A method of performing resource allocation in OFDM transmission, comprising the steps of: 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 said regions of sub-carriers; and allocating said resources for communication with at least one user equipment in at least one region of sub-carriers based on said partitioning and dependent on said characteristic assigned to said regions of sub-carriers. This allows fast resource allocation with low signalling effort as well as fast adjustment to changing system settings or changing systems conditions while providing a possible alternative to costly handover procedures.
