Abstract

The invention relatest to methods and apparatus for coordination of sending reference signals from multiple cells. Methods and apparatus for coordination of sending reference signals in wireless network are disclosed. A network node may select a cell ID based on a measurement of adjacent cells so as to mitigate interference. A network node may communicate information to another network node to control transmitted resources in a protected interval so as to measure channel characteristics.
