摘要： Precoding information is provided (implicitly or explicitly) to a particular user equipment UE. Closed-loop spatial coding for a control channel is selected for the particular user equipment, and at least one control channel element CCE is determined within the particular user equipment's search space of the control channel that is associated with the provided precoding information. The determined at least one CCE is spatially encoded using the provided precoding information to schedule radio resources for the particular user equipment. The UE determines a search space for a control channel, and from received radio resource control signaling determines at least one CCE within the search space that is to be encoded with closed-loop spatial coding. The UE decodes the determined at least one CCE within the search space using a closed-loop spatial decoding with precoding information associated with the at least one CCE to find radio resources scheduled for the particular UE.
