Claim 0:
1. A user equipment configured to operate in a cellular communications network, comprising:
a radio subsystem; and
a processing subsystem associated with the radio subsystem configured to:
receive a downlink subframe via the radio subsystem, the downlink subframe comprising a downlink control channel from the cellular communications network wherein a search space associated with the downlink control channel comprises a plurality of sets of downlink control channel physical resources;
assume that one or more antenna ports in the plurality of sets of downlink control channel physical resources is/are quasi co-located with respect to an antenna port of interest in the search space in accordance with one or more predefined rules that define which of the one or more antenna ports is/are quasi co-located for the downlink control channel; and
utilize the assumption to estimate one or more large-scale channel properties associated with the antenna port of interest.
