1. A first network node for wireless communication, comprising:
a memory;
a first circular antenna array comprising a first quantity of antenna subarrays, wherein each antenna subarray of the first circular antenna array comprises one or more antenna elements; and
at least one processor coupled to the memory, wherein the at least one processor is configured to:
generate one or more signals for transmission from the first network node via the first circular antenna array; and
cause transmission of the one or more signals via the first circular antenna array, wherein each signal of the one or more signals is based on a respective orbital angular momentum vector of a plurality of orbital angular momentum vectors, wherein the plurality of orbital angular momentum vectors is based on a numerical relationship between the first quantity of antenna subarrays of the first circular antenna array and a second quantity of antenna subarrays of a second circular antenna array, wherein each antenna subarray of the second circular antenna array comprises one or more antenna elements, and wherein the numerical relationship comprises:
the first quantity being equal to a product of the second quantity and a non-integer rational number; and
the first quantity and the second quantity having a greatest common divisor that is an integer that is greater than one.
