RESOURCE UNIT MAPPING METHOD IN A WIRELESS COMMUNICATIONS SYSTEM AND A DEVICE THEREOF, CAPABLE OF ACHIEVING SPECTRAL EFFICIENCY AND SYSTEM FLEXIBILITY

摘要

PURPOSE: A resource unit mapping method in a wireless communications system and a device thereof are provided to obtain frequency diversity gain by mapping PRU(Physical Resource Unit)s into CRU(Contiguous Resource Unit)s and DRU(Distributed Resource Unit)s.;CONSTITUTION: A terminal obtains the number of sub band based CRUs and mini band based CRUs(S100). The terminal obtains the number of CRUs and DRUs in ith frequency partition(S110). The terminal maps PRUs of the ith frequency partition with the CRUs(S120). The terminal maps RPUs, which are not allocated to the CRUs, with the DRU(S130).;COPYRIGHT KIPO 2010
