Abstract: The traditional resource allocation algorithms mainly aim at reducing the required resource units, without considering the interference suppression of multicast/broadcast single frequency network (MBSFN). Therefore, an interference suppression based adaptive resource allocation algorithm in MBSFN (IS-ARAAM) is proposed. The topology relationship between MBSFNs is modeled and the transmit power of base station is also taken into consideration when calculating the reuse distance. Then IS-ARAAM is obtained according to the reuse distance. Simulations demonstrate IS-ARAAM is more effective to improve the rate and coverage of network comparing to traditional algorithms. Meanwhile, IS-ARAAM also provides a way to control the number of required resource blocks through adjusting the reuse distance.
