  • Patent number: 10027435
    Abstract: In an automatically switched optical network operating according to a wavelength plan, the wavelengths are assigned to an optical path based on availability, performance and SRS wavelength coupling reduction. First, the wavelengths are grouped in static bins based on their reach versus cost performance, and each bin assumes a ?Q of a middle wavelength. Then, the bins are moved into subsets of dynamic bins, constructed using bin constraints that account for the particulars of the respective optical path. The path is characterized taking into account the wavelength currently accessing at the end nodes, and the wavelength tandeming through the end nodes. Wavelength selection starts with the bins that satisfy the maximum number of constraints, and the wavelengths are checked sequentially against wavelength constraints; relaxed constraints are also applied when it is not possible to exactly satisfy one or more constraints.

  • Publication number: 20180192386
    Abstract: A method and apparatus for timing adjustment in a communication network. In a mobile network, one or more mobile stations (UEs) communication with a common base station (BS) for access to a core network. To align multiple uplink signals and reduce interference, a reference OTL is broadcast from the BS and received at the one or more UEs, the ROTL representing a real or theoretical maximum OTL (one-way trip latency). A universal time reference is then broadcast, often with other data, from the BS and is received by the one or more UEs. Each UE, if it is able, calculates its own OTL and uses that to calculate an ?OTL representing an uplink transmission delay. In some cases, an ?OTL? may be calculated representing an uplink transmission delay that takes into account motion of the UE, if any. In some implementations, timing adjustments may be calculated by the BS and sent to individual UEs if necessary.
