1. User equipment comprising:
a first antenna and a second antenna;
a receiver coupled to the first antenna and the second antenna; and
processing circuitry coupled to the receiver, the processing circuitry configured to
cause the receiver to receive a first signal via the first antenna,
cause the receiver to receive a second signal via the second antenna, each of the first signal and the second signal comprising an in-phase sample and a quadrature sample, the in-phase sample and the quadrature sample each comprising a preamble, a broadcast interval, a broadcast section, and a unicast section,
adjust the first signal based on a first time offset and a first frequency offset associated with the first signal to generate a first adjusted signal,
adjust the second signal based on a second time offset and a second frequency offset associated with the second signal to generate a second adjusted signal,
combine the first adjusted signal and the second adjusted signal to generate a combined signal, and
decode downlink information based on the combined signal.
