摘要： Establishing communications between a plurality of nodes includes determining a set of frequencies to search for neighbor nodes, and performing an adaptive control channel initialization operation to detect zero or more neighbor nodes. If one or neighbor nodes are detected, an adaptive control channel with one or more of the one or more detected neighbor nodes is established.

摘要： An optical isolation structure is incorporated into a display between the display elements and the transparent substrate for the display elements. The optical isolation structure reflects light rays within the substrate that impact the structure at high angles relative to normal to the structure, thereby permitting the substrate to be used as an integrated light guide for distributing light over the display from a light source on the edge of the substrate. The optical isolation structure may include a single layer having an index of refraction less than the substrate or a plurality of thin-film interference layers.

摘要： In one embodiment, a method for generating an adaptive air interface waveform includes generating a waveform that includes a variable carrier frequency and variable bandwidth signal. The variable bandwidth signal includes one or more subcarriers that are dynamically placeable over a range of frequencies, and each subcarrier is separately modulated according to a direct sequence (DS) spread spectrum (SS) technique. The waveform has an embedded pilot usable to optimize one or more spectrum efficiencies of the waveform. A modulation constellation, a code rate, and a code length of the generated waveform are adapted according to an available spectrum and one or more sub-carrier conditions.

摘要： Scheduling communication between a first node and one or more neighbor nodes includes, at each of the first node and the one or more neighbor nodes determining a neighborhood of the one or more neighbor nodes; classifying each of the first node and one or more of the neighbor nodes as one of a transmitting node or a receiving node for a time slot; and determining one or more links, wherein each link is defined by a pair of nodes and an associated bearer frequency, and wherein at least two of the links have different associated bearer frequencies; and scheduling one or more links for the time slot.

摘要： Communicating between a plurality of nodes includes scanning a set of frequencies to determine spectrum awareness data for one or more frequencies; determining a maximum transmit power for one or more of the frequencies based at least in part on the spectrum awareness data for the frequencies; determining one or more channels, each channel occupying at least a portion of the set of frequencies; and selecting one or more of the one or more channels as a bearer.
