Abstract
Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for identifying gesture. A radar antenna array applied to mobile User Equipment (UE) includes a transmit (Tx) antenna array located on a horizontal line and configured to transmit radar waves and a receive (Rx) antenna array including horizontal Rx antennae arranged along a horizontal dimension and/or pitch Rx antennae arranged along a pitch dimension. The horizontal dimension and the pitch dimension are perpendicular to each other. The Rx antenna array is configured to receive echoes caused by reflection of the radar waves. The horizontal Rx antennae are located on the horizontal line where the Tx antenna array is located. The pitch dimension is perpendicular to the horizontal line. A transmitting parameter for transmitting the radar waves and a receiving parameter for receiving the echoes are used at least for identifying a gesture within a radiation range.
