Title: BEAMFORMED PHYSICAL DOWNLINK CONTROL CHANNEL
Abstract:
Embodiments of beamformed physical downlink control channel (B-PDCCH) are generally described herein. A user equipment (UE) decodes an indication of a transmission mode for a beamformed physical downlink control channel (B-PDCCH) received from a network entity. The UE decodes one or more symbol blocks corresponding to a downlink (DL) control region of a subframe, wherein the DL control region includes one or more control clusters, and wherein one discrete Fourier transform (DFT) spreading window is applied in each of the one or more control clusters. The UE determines a B-PDCCH search space according to the indicated transmission mode, wherein the B-PDCCH search space is a set of B-PDCCH candidate locations. The UE performs blind decoding of one or more B-PDCCHs based on the determined B-PDCCH search space, to obtain downlink control information transmitted from one or more evolved NodeBs (eNBs) to the UE via the one or more B-PDCCHs.
