The repeater node is designed for dual-polarized beamforming aimed at user equipment. It features two antenna arrays: the first array communicates with a network node's transmission and reception point, while the second array interacts with the user equipment. The first array includes antenna elements with two different polarizations, and the second array also contains elements with two distinct polarizations. A key feature is the circuitry that connects elements from the first array to those in the second array, allowing for versatile beamforming capabilities.
With the introduction of millimeter waves (mmWaves) for 5G telecommunication systems, communication faces challenges due to physical obstructions. To boost data rates and manage more user equipment, network densification through various access points is considered. Integrated access and backhaul (IAB) nodes are common in 5G for relaying signals but are energy-intensive and complex. Repeaters, while simpler and less energy-consuming, lack advanced chains for receiver and transmitter functions, limiting their use in dual-polarized beamforming scenarios.
The repeater node addresses these issues by enabling dual-polarized beamforming. It comprises a first antenna array linked to a network node and a second array connected to user equipment. The arrays are configured to allow flexible connectivity between different polarized elements via internal circuitry. This setup facilitates efficient signal transmission from the network node to user equipment, overcoming obstacles that block direct line-of-sight communication.
The node operates by receiving signals through the first antenna array, forwarding them internally, and transmitting them via the second array to the user equipment. The controller module, equipped with processing circuitry, manages these operations, ensuring effective beamforming and power control. This module can communicate with the network, either wired or wirelessly, to receive control signals and update network status.
The repeater node's design allows for efficient dual-polarized beamforming, creating flexible beamwidths and shapes without compromising power efficiency. This makes it suitable for deployments requiring adaptable signal transmission, such as in synchronization signal blocks or broadcast and multicast scenarios. The node's reduced complexity and energy requirements compared to traditional nodes offer a cost-effective solution for enhancing 5G network performance.
