Abstract:
Techniques for transmitting and receiving beamformed transmission(s) of a common search space of a DL (Downlink) control channel are discussed. One example embodiment that can be employed at a UE (User Equipment) comprises processing circuitry configured to: select a set of receive beamforming weights for a DL (Downlink) control channel; and decode one or more control channel sets from a common search space of the DL control channel, wherein each control channel set of the one or more control channel sets is mapped to an associated symbol of one or more symbols of a slot, wherein each control channel set of the one or more control channel sets has an associated transmit beamforming, and wherein each control channel set of the one or more control channel sets comprises a common set of control information.
