<p><P>PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate frequency hopping in a single carrier FDMA wireless environment. <P>SOLUTION: Systems and methodologies are described that facilitate frequency hopping in a single carrier FDMA wireless environment by dynamically altering user offsets with time to obtain interference diversity. A channel tree can be utilized with nodes that are assigned values. User devices are assigned to such nodes, a path between an assigned node and a root node in the channel tree is evaluated, and a table lookup is performed to determine an identity of a subcarrier set to assign to the user device assigned to a given node, as well as the number of subcarriers to be assigned to the user device. Additionally, node values is dynamically varied during a communication event to alter path values and thus alter subcarrier set assignments. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
