METHOD AND DEVICE FOR ALLOCATIONG FREQUENCY RESOURCE BLOCK IN UPLINK SC-FDMA SYSTEM

摘要

PURPOSE: A frequency sub channel allocation method in a uplink SC-FDMA(Single Carrier Frequency Division Multiple Access) and apparatus thereof are provided to solve a problem which a user receives a plurality of frequency sub channels by preventing the congestion of channels. CONSTITUTION: A base station selects a first terminal and a first sub channel which are able to obtain a maximum transmission rate gain(S400). The base station selects a terminal which includes the maximum transmission rate gain of second terminals as a replacement terminal(S410). A first terminal allocation transmission rate gain and a single frequency sub channel are compared with a replacement terminal allocation transmission gain when a first frequency sub channel is allocated to the terminal. The first frequency sub channel is allocated to a first terminal or the replace terminal according to a comparison result(S430). [Reference numerals] (AA) Start; (BB) Yes; (CC) No; (DD) End; (S400) A first terminal and a first frequency sub-channel are selected for obtaining a maximum transmission rate gain; (S410) A replacement terminal is selected; (S420) A frequency sub-channel is allocated to a replacement terminal or a first terminal; (S430) Number of allocatable frequency sub channels > 0 ?
