Abstract: A dynamic resource allocation method in an OFDMA system is provided. A base station determines if each of a plurality of SSs supports subchannel-based dynamic resource allocation. If an SS supports the subchannel-based dynamic resource allocation, the base station allocates resources to the SS on a subchannel basis. If the SS does not support the subchannel-based dynamic resource allocation, the base station allocates resources to the SS on a burst basis.

Abstract: The present invention relates to an iterative decoding receiver for reducing complexity of a partial sphere decoding operation in a spatial multiplexing system, and a method thereof. In the present invention, an iterative detection and decoding (IDD) method using a cost function-based iterative partial sphere decoding method and a soft cancellation-based iterative partial sphere decoding method is used to correct an initial estimation error. In a channel encoding spatial multiplexing system, since the iterative decoding receiver using decoding algorithms including a BCJR algorithm, an MPA, and a VA performs an SISO sphere decoding operation providing an optimum detection solution, the iterative decoding receiver may detect transmission symbols at a whole dimension by detecting the transmission symbols at a partial dimension, and therefore the complexity of the SISO sphere decoding operation may be greatly reduced.
