Abstract
Self-optimization in heterogeneous networks techniques are provided. In autonomous mode, certain self-optimization criteria are used to set up one or more targets with same or different priorities. The cells in a defined area of a HetNet autonomously adjust certain radio resources (e.g., power, time, frequency, and/or spatial resources (e.g. antenna, location)) in order to achieve or to be close to the targets such that the self-optimization criteria are met. In a coordinated mode, certain self-optimization criteria are used to define one or more cost functions with same or different priorities. The cells or a subset of users in the cells in a defined area of a HetNet search for the optimal solution for the cost functions by coordinating certain radio resources.
