AI Technical Summary

Benefits of technology

This approach improves MU-MIMO performance and capacity in communications systems with small numbers of antennas, achieving results similar to or better than systems with more antennas, while reducing complexity and cost.

Problems solved by technology

However, the performance improvement for communications systems with small numbers of antennas, such as 4 or 8 antennas, per evolved NodeB (eNB) may be disappointing in light of the increased complexity and cost of the communications system.
This has limited the popularity of such communications systems for deployment.

Embodiment Construction

[0036]The operating of the current example embodiments and the structure thereof are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific structures of the disclosure and ways to operate the disclosure, and do not limit the scope of the disclosure.

[0037]One embodiment of the disclosure relates to MU-MIMO communications. For example, a communications controller schedules a pair of user equipments (UE) located in different ones of a plurality of split beams using an appropriate code pair that produces the the plurality of split beams for multi-user multiple-input multiple output (MU-MIMO) mode transmission, and transmits data packets to the pair of UEs in accordance with the appropriate code pair.

[0038]The present disclosure will be described with respect to example embodimen...

Abstract

A method for operating a communications controller in a wireless communications system includes scheduling a pair of user equipments (UE) located in different ones of a plurality of split beams using an appropriate code pair that produces the plurality of split beams for multi-user multiple-input multiple output (MU-MIMO) mode transmission, and transmitting data packets to the pair of UEs in accordance with the appropriate code pair.

Description

[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 724,639, filed on May 28, 2015 and entitled “System and Method for Multi-User Multiple Input Multiple Output Communications,” which claims priority to U.S. Provisional Application No. 62 / 082,647, filed on Nov. 21, 2014, entitled “MU-MIMO Split-Beam Antenna System and Method,” both of which applications are hereby incorporated herein by reference herein as if reproduced in their entireties.TECHNICAL FIELD[0002]The present disclosure relates generally to digital communications, and more particularly to a system and method for multi-user multiple input multiple output (MU-MIMO) communications.BACKGROUND[0003]In modern communications systems, such as The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) compliant communications systems, MU-MIMO with multiple antennas is a key component in improving overall communications system throughput. However, the performance improvement for communic...
