Abstract

Provided is a method for dynamic resource allocation of uplink and downlink in an OFDMA/TDD cellular system. The method for dynamic resource allocation of uplink in an OFDMA/TDD cellular system includes the steps of determining the number of sub-channels which can be allocated to each user through an FLR algorithm; performing channel allocation for a first frame through a round-robin algorithm in which channel information is not needed; performing dynamic channel allocation for a next frame through uplink channel information measured by uplink channel sounding; and performing power control. The method for dynamic resource allocation of downlink in an OFDMA/TDD cellular system includes the steps of selecting a user through a GPF algorithm; performing dynamic channel allocation through an ASA algorithm so as to perform a FASA algorithm for obtaining a multiuser diversity gain; and performing dynamic power allocation through an improved CHC algorithm, in consideration of a data rate provided to each user and a channel state.
