Systems and methods for delay based power ramping of devices
In LTE Random Access Channel (RACH) mechanism, devices use slotted ALOHA based protocol for RACH message exchange.

The embodiments further enable requests transmission from device to BS by ramping power of the devices based on the computed TD. |

Metamaterials for surfaces and waveguides
Complementary metamaterial elements provide an effective permittivity and/or permeability for surface structures and/or waveguide structures. The complementary metamaterial resonant elements may include Babinet complements of “split ring resonator” (SRR) and “electric LC” (ELC) metamaterial elements. In some approaches, the complementary metamaterial elements are embedded in the bounding surfaces of planar waveguides, e.g. to implement waveguide based gradient index lenses for beam steering/focusing devices, antenna array feed structures, etc. |

Multi-frequency antenna
A multi-frequency antenna comprises a substrate disposed on a clearance area of a circuit board, and a first resonance unit and a second resonance unit located on the surface of the substrate or within the substrate. The first resonance unit is connected to a signal feeding terminal of the circuit board and connected to the second resonance unit via a first filtering element. The first resonance unit forms the first resonance frequency of the multi-frequency antenna, and the first resonance unit, the first filtering element, and the second resonance unit all together form the second resonant frequency. The first filtering element shows a high impedance towards the signal with the first resonant frequency and a low impedance towards the signal with the second resonant frequency. Thus, an antenna with multiple resonant frequencies can be obtained. The material and manufacturing costs of the multi-frequency antenna can thereby be reduced. |
