Resource allocation for OFDM transmission with subcarriers partitioning and bilateral cell subcarriers exchange

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 of sub-carriers 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. Said characteristic is for instance the transmit power.
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.
