System and method for dynamically allocating resources in a mobile communication system employing orthogonal frequency division multiple access |
摘要 |
A system and method for dynamically allocating a frame cell (FC) and subchannel (FC/subchannel) is disclosed. An access point receives channel quality information (CQIs) which is fed back from a plurality of access terminals on an FC-by-FC basis, and determines a modulation and coding scheme (MCS) to be applied to each of the access terminals. If access terminals whose FCs/subchannels must be changed are detected from the plurality of the access terminals, the access point sends an FC/subchannel change request for the detected access terminals to an access router. The access router generates weights for all FCs, allocates an FC/subchannel set by selecting a predetermined number of FCs/subchannels considering the weights of the FCs for the access terminals corresponding to the received FC/subchannel change request, and transmits information on the allocated FC/subchannel set to the access point. The access point selects and allocates a particular FC/subchannel from among FCs/subchannels in the FC/subchannel set information received from the access router for the access terminals whose FCs/subchannels must be changed, based on CQIs last received from the access terminals whose FCs/subchannels must be changed.
