Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support rotational alignment of a first antenna panel of a first device and a second antenna panel of a second device. The first and second devices may exchange signaling that indicates a panel rotation capability and a panel rotation procedure configuration based on the panel rotation capability. The second device may transmit a reference signal from a central antenna element of the second antenna panel based on the configuration. The first device may receive the reference signal via two antenna elements of the first antenna panel and may adjust an angular rotation of the first antenna panel based on the reference signal to modify a respective distance between each of the two antenna elements of the first antenna panel relative to the central antenna element of the second antenna panel.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, such as a user equipment (UE) or base station, may receive, at a first antenna of a first antenna array, a first set of reference signals. The first device may measure the phase for each of the reference signals and estimate a linear offset between the first antenna array and a second antenna array of a second device that transmitted the reference signals. The first device may adjust an alignment of the first antenna array according to the estimated linear offset. The first device may receive a second set of reference signals, measure the phase for each of the reference signals, and estimate one or more rotational offsets between the first antenna array and the second antenna array. The first device may adjust the alignment of the first antenna array based on the one or more rotational offsets.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a second wireless node, an indication of an orbital angular momentum (OAM) base value that is associated with one or more OAM modes. The OAM base value may correspond to a number of antenna elements of an antenna ring at the first wireless node, and for each of the one or more OAM modes. Based on the OAM base value, the first wireless node may communicate reference signaling according to the one or more OAM modes using the number of antenna elements of the antenna ring. The second wireless node may use a same number of antenna elements based on the indicated OAM base value.
