PERMUTATION DEVICE AND METHOD HAVING IMPROVED RESOURCE GRANULARITY FOR WIRELESS COMMUNICATIONS

摘要

A device and method for permuting subcarriers in a subframe which is divided into a plurality of frequency partitions in a wireless mobile communication system is disclosed. The method includes mapping, at a mobile station, physical resource units for localized resource allocation to a frequency partition of the plurality of frequency partitions in units of N_l number of resource units, and physical resource units for distributed resource allocation to the frequency partition in units of N_d number of resource units, N_l being different from N_d; and spreading, at the mobile station, subcarriers of the physical resource units for distributed resource allocation across the whole distributed resource allocations.
