A method for compressive channel estimation in a massive multiple input, multiple output (MIMO) system using sectored random beams is provided. In an embodiment, a method in a massive multiple input, multiple output (MIMO) transceiver for channel estimation includes obtaining a sector. The sector includes less than a complete coverage area of the transceiver. The method also includes transmitting, by the transceiver, a plurality of random beams to a user equipment (UE) in the sector.
