22. A method, comprising:
transmitting, by a node to another node, information related to two or more angle error groups, wherein the two or more angle error groups comprise one or more antenna elements, wherein the information comprises identifiers for the two or more angle error groups;
performing one or more angle of arrival measurements based on signals received at at least one angle error group of the two or more angle error groups;
determining, based on the one or more angle of arrival measurements, an angle of arrival for the at least one angle error group; and
transmitting, to the other node, the determined angle of arrival and an identifier for the at least one angle error group associated with the determined angle of arrival for determination of a user equipment location.
