Embodiment Construction

[0043] The current subject matter can provide systems and methods that can be implemented in a layer 1 partitioned architecture for a wireless communication system. Such systems may include long term evolution wireless communication systems and / or new radio communication systems. The current subject will incorporate the use of multiple-input multiple-output ("MIMO") techniques along with hybrid analog / digital beamforming into a layer 1 partitioning architecture. Centralized upper physical ("PHY") layer processing may be implemented. Layer 1 can be partitioned and frequency domain compression can be achieved (eg, to reduce bandwidth). Signals from user equipment may be received from multiple sites.

[0044] One or more aspects of the current subject matter may be incorporated into transmitter and / or receiver components of a base station in such a communication system. An exemplary Long Term Evolution communication system is described below.

[0045] I. Long Term Evolution C...

Abstract

A system, a method, and a computer program product for transmission of data using a multiple input, multiple output communications system with hybrid beamforming in a layer 1 split architecture. A first portion of a signal is processed at a first portion of a physical layer located in a first portion of a base station. A frequency domain compression with statistical multiplexing is applied to theprocessed first portion of the signal. A compressed first portion of the signal is generated. The compressed first portion of the signal and a second portion of the signal are transmitted to a secondportion of the physical layer located in a second portion of the base station.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims Lee's U.S. Patent Office entitled "Multi-Site MIMO Communications System With HybridBeamforming In L1-Split Architecture", filed February 6, 2017 Priority to Provisional Patent Application No. 62 / 455,315, which is hereby incorporated by reference in its entirety. technical field [0003] In some embodiments, the current subject matter relates to telecommunications systems, and in particular, to multiple-input multiple-output ("MIMO") communication systems with hybrid beamforming in a layer-1 split architecture, wherein the communication systems may include 5G New Radio ( "NR") communication system. Background technique [0004] In today's world, cellular networks provide on-demand communication capabilities to individuals and business entities. Generally, a cellular network is a wireless network that can be distributed over land areas called cells. Each such cell is served by at least one fixe...
