Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a control message indicating a set of sampling beams defined for the UE. The UE may measure a set of received signal strengths for communications from a wireless node associated with a set of linear combinations of sampling beams from the set of sampling beams defined at the UE. The UE may calculate a set of entries of a channel covariance matrix based on the set of received signal strengths of the set of linear combinations of the sampling beams from the set of sampling beams defined for the UE. As such, the UE may communicate with the wireless node based on applying a set of beam weights to an antenna array of the UE. In some examples, the set of beam weights may be based on the channel covariance matrix.

Abstract: Aspects relate to an array antenna and communication using the array antenna. In some examples, the array antenna includes a first array of antenna elements arranged according to a first circle and a second array of antenna elements arranged according to a second circle, where the first circle and the second circle are concentric circles. In some examples, the first array of antenna elements is arranged with an angular offset with respect to the second array of antenna elements. For example, a first radius associated with a first antenna element of the first array of antenna elements may be offset at an angle with respect to a second radius of a second antenna element of the second array of antenna elements.
