Embodiment Construction

[0020] The configuration and use of the currently preferred embodiment will be discussed in detail below. However, it should be understood that the present invention provides many applicable inventive concepts that can be implemented in various specific contexts. The specific embodiments discussed only show specific ways to construct and use the invention, and do not limit the scope of the invention.

[0021] The massive MIMO system includes multiple RRUs. These RRUs can be derived from centralized digital transceiver units that can be located several kilometers (km) away. Since there is hardware on the RRU that needs to be controlled according to the data being sent, it has been found that it is desirable to have a mechanism to transfer control information from the digital transceiver unit to the RRU, so that the hardware complexity at the RRU will not increase too much. many.

Abstract

System and method embodiments are provided for remote radio unit (RRU) control messaging in massive multiple input multiple output (MIMO) systems. In an embodiment, a network component in a MIMO wireless communication system includes a digital transceiver configured to generate a data signal and a control signal, the control signal including one of control information to control analog componentson a RRU and status information about analog components on the RRU; a modulator configured to modulate the control signal onto a control carrier; a transmit filter configured to filter the modulated control signal; and a combiner configured to combine the data signal and the filtered modulated control signal and send the combined signal to a second network component via a physical channel, the second network component comprising one of a controller and the RRU.

Description

[0001] Cross references to related applications [0002] This patent application claims the priority of U.S. Patent Application No. 14 / 793,349 entitled "Systems and Methods for RRUControl Messaging Architecture for Massive MIMO Systems" filed on July 7, 2015. The entire content of the U.S. patent application is reproduced The same is incorporated into this article by reference. Technical field [0003] The present invention relates to a system and method for wireless communication, and in a specific embodiment, to a system and method for control message transfer in a large-scale multiple-input multiple-output radio system. Background technique [0004] A large-scale Multiple Input Multiple Output (MIMO) system includes multiple remote radio units (RRU). These RRUs can receive signals provided by centralized digital transceiver units that can be located several kilometers away. Since there is hardware on the RRU that needs to be controlled according to the data being sent, a mechan...
