Claim of US Patent No. 10,143,037

1. A radio base station, comprising: a transmitter configured to transmit in the downlink direction a first millimeter wave band signal in a licensed frequency spectrum at a high transmit equivalent isotropically radiated power (EIRP), the transmitter comprising: a first signal processing circuit configured to generate the first millimeter wave band signal: a power amplifier configured to amplify the first millimeter wave band signal; a high gain transmit antenna array configured to transmit the first millimeter wave band signal; a receiver configured to receive from the uplink direction a second millimeter wave band signal in an unlicensed frequency spectrum at a high receive gain, the receiver comprising: a high receive gain antenna array configured to receive the second millimeter wave band signal; a low noise amplifier configured to amplify the second millimeter wave band signal; a second signal processing circuit configured to process the second millimeter wave band signal.
