摘要： A method can include providing channel feedback to support efficient rank override For example, in such a method, a rank−r precoder index corresponding to a rank−r precoder is determined, and performance for each rank−1 precoder within the rank−r precoder is measured Based on the measured performance, a rank−1 precoder that maximizes performance is selected.

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.

摘要： An apparatus and method for initialization and mapping of reference signals in a communication system. In one embodiment, the apparatus includes a processor and memory including computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to generate a reference signal employable with a plurality of physical resource blocks corresponding to a bandwidth of a communication system, and allocate resource elements of an assigned physical resource block from the plurality of physical resource blocks to a user equipment. The memory and the computer program code are further configured to, with the processor, cause the apparatus to generate a dedicated reference signal for the user equipment by allocating elements of the reference signal in accordance with allocated resource elements of the assigned physical resource block.
