Wireless devices and methods of communication

Abstract

The term refers to the wireless communication equipment and methods. The base station can pre-encode the first reference signal using the first pre-encoder (P!) and at least one second reference signal using at least one second pre-encoder (P2). At least two UEs can measure the first reference signal and at least one second reference signal, and transmit channel state feedback based on the measurements (m1 and m2 for the first UE, and m21 and m22 for the second UE). Channel state feedback can include channel state information compressed by at least one neural network. The base station can infer a higher-order precoder (for multiple-input multiple-output (MIMO) downlink transmission to at least two UEs).
