Reducing Initial Cell-search Latency in mmWave Networks
Millimeter-wave (mmWave) networks rely on directional transmissions, in both control plane and data plane, to overcome severe path-loss. Nevertheless, the use of narrow beams complicates the initial cell-search procedure where we lack sufficient information for beamforming. In this paper, we investigate the feasibility of random beamforming for cell-search. We develop a stochastic geometry fram...
متن کاملRobust and High Throughput Beam Tracking for mmWave Communication Systems
Millimeter-wave (mmWave) communication has been considered as a promising communication system with large spectrum resource available. In mmWave communication systems, in order to overcome severe path-loss, beamforming technology is required to form narrow beam and generate high directional antenna gain. This will result in frequent beam handoff and severe link blockage, especially in mobile sc...
متن کاملNaNet: a flexible and configurable low-latency NIC for real-time trigger systems based on GPUs
NaNet is an FPGA-based PCIe X8 Gen2 NIC supporting 1/10 GbE links and the custom 34 Gbps APElink channel. The design has GPUDirect RDMA capabilities and features a network stack protocol offloading module, making it suitable for building low-latency, real-time GPU-based computing systems. We provide a detailed description of the NaNet hardware modular architecture. Benchmarks for latency and ba...
متن کاملApplication of Motion Sensors for Beam-Tracking of Mobile Stations in mmWave Communication Systems
In a millimeter wave (mmWave) communication system with transmit/receive (Tx/Rx) beamforming antennas, small variation in device behavior or an environmental change can destroy beam alignment, resulting in power loss in the received signal. In this situation, the beam-tracking technique purely based on the received signal is not effective because both behavioral changes (rotation, displacement)...
متن کاملFlexible Information Discovery in Decentralized Distributed Systems
The ability to efficiently discover information using partial knowledge (for example keywords, attributes or ranges) is important in large, decentralized, resource sharing distributed environments such as computational Grids and Peer-to-Peer (P2P) storage and retrieval systems. This paper presents a P2P information discovery system that supports flexible queries using partial keywords and wildc...
