A central node of a Massive Multiple-Input-Multiple-Output (MIMO) system includes a processor and a transceiver. The processor is configured to determine a number of active antennas to be used to serve users in at least one cell of the Massive MIMO system based on wireless network parameters for the Massive MIMO system. The transceiver is configured to transmit the determined number of active antennas to a Massive MIMO base station in the at least one cell.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
