Abstract
A message contains global carrier configuration is provided in a wireless multi-carrier orthogonal frequency division multiplexing (OFDM) system. The global carrier configuration contains global carrier configuration information such as the center frequencies for multiple available RF carriers of different base stations in the OFDM network. In one embodiment, the global carrier configuration comprises information of single or multiple carrier groups, each carrier group comprises single or multiple contiguous RF carriers, and each carrier group is associated with a multi-carrier configuration index that refers to carrier configuration information contained in a carrier configuration lookup table and a frequency assignment index that refers to a global frequency location contained in a frequency assignment lookup table.
