1. A method, comprising:
- determining a time variation in an interference level experienced by a receiver;
generating a first channel estimate of a wireless communication channel as of a first time;
generating a second channel estimate of the wireless communication channel as of a second time;
weighting the first channel estimate and the second channel estimate in accordance with the time variation, thereby generating a first weighted channel estimate and a second weighted channel estimate; and
computing a weighted channel estimate based upon the first weighted channel estimate and the second weighted channel estimate.

Abstract
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.
