Systems and methods are disclosed that facilitate dynamically assigning system resources in a wireless network environment by detecting a resource conflict between an existing resource assignment to one or more existing user devices and a new resource assignment for a subsequent user device. Upon detection of a conflict, a decremental assignment can be provided to the one ore more existing user devices to decrement the existing resource assignment in order to resolve a detected resource conflict. Decremental assignments can be implicit or explicit, and can facilitate mitigating transmission overhead costs due to their relatively small size when compared to conventional complete deassignment/reassignment messages.
