FIELD: radio engineering and communications.
SUBSTANCE: invention relates to a communication system, particularly, to quasi-combined antenna ports in cellular communication network. In one embodiment, a wireless device receives a downlink subframe including downlink control channel, from a cellular communication network. Wireless device evaluates one or more global properties of the channel for the target antenna port in downlink control channel based on a subset of reference signals, which correspond to antenna ports in cellular communication network, which are quasi-combined with the target antenna port in relation to one or more global properties of the channel.
EFFECT: invention relates to improved methods for channels evaluation.
