Abstract

The invention discloses a centralized control beamforming method for 5G C-RAN, which decouples a weight control module in beamforming from an antenna unit. At the same time, a control unit of the beamforming weights at different RRUs in the C-RAN is decoupled and deployed centrally at the BBU Pool of the C-RAN to provide a unified beam management and optimization platform for real-time delay-basedPAA beamforming for smooth evolution of the C-RAN architecture.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically, relates to a 5G C-RAN-oriented centralized control beamforming method. Background technique [0002] In the field of wireless communication, cloud radio access network (C-RAN) is a promising architecture for next-generation systems, and its baseband processing is concentrated in a virtual pool composed of baseband units (BBU) - BBU Pool. Compared with the traditional wireless access network architecture, its power and energy consumption are effectively reduced, and it has the potential to reduce network operation costs. [0003] On the other hand, space division multiplexing technology can greatly improve the capacity of wireless communication. For the realization of space division multiplexing technology, phased antenna array (PAA) has steering ability and compact structure, and has been widely researched and applied. Compared with the beamforming method b...
