Abstract
Methods, systems and devices for reciprocal geometric precoding are described. One example method includes determining, by a network device, an uplink channel state using reference signal transmissions received from multiple user devices, and generating a precoded transmission waveform for transmission to one or more of the multiple user devices by applying a precoding scheme that is based on the uplink channel state, wherein the uplink channel state completely defines the precoding scheme. In some embodiments, the reference signal transmissions and the precoded transmission waveform are multiplexed using either time-domain multiplexing or frequency-domain multiplexing.
