Coordinated transmission in millimeter wave systems
Certain aspects of the present disclosure provide techniques for coordinated transmissions in certain systems, such as millimeter wave (mmW) systems. A method of wireless communication by a user equipment (UE) generally includes providing an indication to a plurality of base stations (BSs) of one or more selected beams for transmission by each of the plurality of BSs. The method includes determining one or more co-phase factors. The method includes receiving a coordinated transmission from the plurality of BSs based on the one or more selected beams and the one or more co-phase factors. A method by a BS generally includes receiving the indication from the UE of the one or more selected beam, determining one or more co-phase correction factors, and sending a coordinated transmission to the UE based, at least in part, on the one or more selected beam and the one or more co-phase correction factors.
