The control transmission portion is divided into a plurality of control transmission portion sub-regions, each sub-region scheduling a data transmission for a corresponding sub-region of a data transmission portion of the mmWave communication. Then a first of the control transmission portion sub-regions is demodulated and decoded. A receive analog antenna beamforming is armed according to the demodulated and decoded first of the control transmission portion sub-regions. Beamforming is performed on a first sub-region of the data transmission portion of the mmWave communication, the first sub-region of the data transmission portion corresponding to the first of the control transmission portion sub-regions. During the arming and performing, a second of the control transmission portion sub-regions is demodulated and decoded. ## Claims ### Claim 1 A method comprising: receiving, by a user equipment (UE), a physical downlink control channel (PDCCH) containing information for receiving a physical downlink shared channel (PDSCH), the information in the PDCCH including a first receive beamforming parameter indicator field, the first receive beamforming parameter indicator field indicating at least one receive beamforming parameter;
