Abstract
Aspects of the disclosure relate to formula-based inter-circle precoding weight determination for orbital angular momentum (OAM) communication systems. Some aspects of the disclosure relate to apparatuses and methods for wireless communication, an apparatus comprising: a processor, antenna elements, comprising a first subset and a second subset of antenna elements; and a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the processor to: transmit, via the first subset of antenna elements, a first reference signal using a first OAM mode; transmit, via the second subset of antenna elements, a second reference signal using the first OAM mode; and receive information indicative of a subset of antenna elements of the plurality of antenna elements to use to transmit the first OAM mode. Other aspects, embodiments, and features are also claimed and described.
