A multi-beam antenna system, apparatus and method for dynamic carrier aggregation to multi-beam antenna mapping in radio access networks, including small-cell deployments, is disclosed. Apparatus comprises a compact base transceiver unit with integrated multi-beam antenna comprising antenna groups configurable for operation in a plurality of modes, with one or more selected antenna groups enabled, for different use-case scenarios. The base transceiver unit comprises a daisy-chained radio-frequency (RF) system wherein one baseband processor feeds multiple RF transceivers; each RF transceiver front end comprises a software configurable isolation module through which each RF front end is interlinked to previous and next RF front ends to enable dynamic routing of TX/RX data streams through the daisy chain, e.g. routing a transmission data stream from any RF transceiver to any one of the antenna groups or multiple antenna groups, routing a received data stream from one or multiple antenna groups to any RF transceiver, and for contiguous or non-contiguous carrier aggregation.

System, apparatus and method for dynamic carrier aggregation to multi-beam antenna mapping

A system and method for reception mode switching in a dual-carrier fixed wireless backhaul network is disclosed. The primary carrier is a licensed band. The secondary carrier may be a lower cost shared band or an unlicensed band. Multi-mode Remote Backhaul Modules (RBMs) comprise a first Radio Frequency (RF) chain with antenna elements for receive/transmit (RX/TX) on the primary carrier and a second RF chain with antenna elements for RX/TX on the secondary carrier. The Multi-mode RBMs adaptively switch from one reception mode to another with resource borrowing of RF and antenna elements, e.g. the secondary carrier RF chain and antenna elements can be borrowed for the primary carrier, for better reception capability for the primary carrier, reducing the number of link-budget and interference-challenged RBMs, and improving system performance. The system may comprise a dual carrier and single carrier Multiple-Input Multiple-Output (MIMO) system with variable antenna topology, having flexibility to switch dynamically between different operational modes depending on performance metrics.
