Description

This book treats the problems of single cell resource allocation, multiple cells resource allocation, centralized resource allocation, distributed resource allocation, the case of collaboration between base stations and the case without base station collaboration, in addition to the case of user cooperation and the case without user cooperation. It is valuable supplemental reading in wireless communications courses, cellular systems courses, and similar courses.
