1. A system for beam management in a wireless network, comprising:
a radio frequency (RF) receiver comprising an antenna array configured to passively receive incoming RF transmissions without coordination between the RF receiver and a source transmitter of the RF transmissions, wherein the incoming RF transmissions do not include a pilot sequence or a synchronization sequence; and
a processing system comprising:
receiver circuitry in communication with the radio frequency receiver to produce in-phase/quadrature (I/Q) input samples from the incoming RF transmissions, and
a learning module comprising a trained classification module operative to receive the I/Q input samples from the receiver circuitry and process the I/Q input samples to determine transmitted beam information of incoming RF transmissions, the learning module further comprising:
a beam inference engine to determine waveform characteristics of the incoming RF transmissions, and
an angle of arrival engine operative to determine angles of arrival of the incoming RF transmissions on the antenna array,
wherein the processing system is further operative to select an incoming RF transmission and angle of arrival based on the determined waveform characteristics for beam management operations; and
an RF transmitter located at a same node with the RF receiver and in communication with the processing system and operative to transmit RF signals at an angle corresponding to the selected angle of arrival without coordination between the system for beam management and the source transmitter of the RF transmissions.
