  In this paper, we propose a method for acquiring accurate and timely channel
state information (CSI) by leveraging full-duplex transmission. Specifically,
we propose a mobile communication system in which base stations continuously
transmit a pilot sequence in the uplink frequency band, while terminals use
self-interference cancellation capabilities to obtain CSI at any time. Our
proposal outperforms its half-duplex counterpart by at least 50% in terms of
throughput while ensuring the same (or even lower) outage probability.
Remarkably, it also outperforms using full duplex for downlink data
transmission for low values of downlink bandwidth and received power.
