Abstract
Systems and methods are disclosed for estimating one or more channel properties of a downlink from a cellular communications network based on quasi co located antenna ports with respect to the one or more channel properties. In one embodiment a wireless device receives a downlink subframe including a downlink control channel from the cellular communications network. The wireless device estimates one or more large scale channel properties for an antenna port of interest in the downlink control channel based on a subset of reference signals that correspond to antenna ports in the cellular communications network that are quasi co located with the antenna port of interest with respect to the one or more large scale channel properties. As a result of using the quasi co located antenna ports estimation of the one or more large scale channel properties is substantially improved.
