Abstract

A user equipment, UE, (24) is configured to receive downlink control information, DCI, transmitted to the UE (24) by a primary cell (26) in a wireless communication system (10). The UE (24) comprises one or more processing circuits (34) that shall assume that a DCI message which has a common payload size and the same first control channel element index, but different bit fields, in a common search space and a UE-specific search space is transmitted by the primary cell (26) in the common search space or the UE-specific search space, based on radio resource control, RRC, configuration of the UE (24).
