Abstract :
The TDD operation mode of UMTS allows highly dynamic and various configurations of the physical layer time frame. A key issue in developing access methodologies to the available spectrum is an optimal management of the rare radio resources. The application of interference based dynamic resource allocation is evaluated and compared to fixed channel allocation. The dynamic allocation is based on an attempt to offer connections instantaneous quality of service. Moreover, it allows rearrangement of the allocated resources in order to increase the connection quality in case of a possible impending connection breakdown. As a decentralised algorithm, dynamic channel allocation offers among its performance gain the ease of implementation while reducing the network planning
