US 2022/0030570 A1 · MIMO ANTENNA ARRAY FOR CROSS DIVISION DUPLEX

Abstract

A radio frequency (RF) unit and method of operation of the RF unit are disclosed herein. The RF unit comprises an antenna array, and the antenna array comprises a plurality of antenna elements. A first set of the plurality of antenna elements is configured to operate in a first mode and a second set of the plurality of antenna elements is configured to operate in a second mode. In the first mode, the first set of the plurality of antenna elements is configured to transmit and receive. In the second mode, the second set of the plurality of antenna elements is configured to only receive.
