MILLIMETER WAVE COARSE BEAMFORMING USING OUTBAND SUB-6GHZ RECONFIGURABLE ANTENNAS

Номер: US20210306042A1

Low latency beamforming using phased antenna arrays is the key for practical deployment of envisioned millimeter wave (mmWave) Gbps mobile networks. This work aims towards reducing the overhead of the exhaustive sector-level sweep phase of the analog beamforming adopted in the IEEE 802.11ad standard. This system uses a reconfigurable antenna single RF chain in the sub-6 GHz new radio (NR) band to aid codebook-based beam selection in the mmWave band of the NR. The system exploits the congruence between the spatial propagation signatures of signals at both mmWave and sub-6 GHz frequencies to reduce the beam search space.

On-chip wireless links offer improved network performance due to long distance communication, additional bandwidth, and broadcasting capabilities of antennas. A Through-Silicon Via (TSV)-based antenna design called TSV_A establishes multi-band wireless communication through the silicon substrate medium with only a 3 dB loss over a 30 mm on-chip distance. Simulation results show an improvement in network latency up to ˜13% (average improvement of ˜7%), energy-delay improvements of ˜34% on average, and an improvement in throughput up to ˜34% (average improvement).
