Abstract
Active antennas are provided. An active antenna includes a main processor that is configured to perform processing of packets from an O-RAN interface of the main processor to provide a plurality of data streams. The active antenna also includes a plurality of secondary processors that are configured to process the data streams from the main processor.
Claims24
An active antenna comprising:
- a main processor comprising an O-RAN front-haul interface and a post-O-RAN interface that is coupled to an output of the O-RAN front-haul interface, the post-O-RAN interface being configured to parse user-plane packets and control-plane packets received from the O-RAN front-haul interface to provide a plurality of output data streams in a frequency domain;
- and
- a plurality of secondary processors that are configured to receive the output data streams, respectively, from the main processor and to transform data of the output data streams from the frequency domain into a time domain.

An active antenna comprising:
- a main processor comprising an O-RAN front-haul interface and a post-O-RAN interface that is coupled to an output of the O-RAN front-haul interface;
- and
- a plurality of secondary processors,
- wherein the main processor is configured to output a plurality of data streams to the secondary processors, respectively, each of the data streams comprising a header that includes control-plane information.
