Wireless resource allocation depending on interference and position of the mobile terminal

摘要

In a conventional OFDMA/SCFDMA communication scheme, frequency resource assignment information is exchanged between BSs via a wired interface and used for control of inter-cell interference or the like. When a BS performs assignments of frequency resources, taking the status of a neighbor BS signaled via the wired interface into account, it might be impossible to follow a change in the status of the assignments of frequency resources at the neighbor BS due to a delay occurring in the wired interface. BS selects and assigns distributed frequency resources or continuous frequency resources, depending on the position of an MS in the cell and the transmit power of the BS.
