  • Patent number: 10862609
    Abstract: In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.

  • Patent number: 10841208
    Abstract: Routing packets through a virtual network (VN) in support of service-based traffic forwarding is provided. Data packets are routed using a virtual router (v-router) toward a destination end point over a pre-configured VN. The v-router is associated with a VN node, which is associated with a physical network node (NN). A data packet associated with the VN is received and a name identifier of the destination end point is specified. A location corresponding to the name identifier is obtained. An indication of a destination VN node corresponding to the location is obtained. An indication of a next VN node on a path between the virtual router and the destination VN node is obtained. The indication of the next VN node is inserted into the packet to produce a routed packet. The routed packet is submitted to the associated NN for transmission toward the next node.

  • Patent number: 10826744
    Abstract: The present invention provides a preamble that is inserted into an OFDMA frame and has a common sequence for all the base stations participating in a transmission. The subscriber station performs fine synchronization using the common sequence on the common preamble, and the resulting peaks will provide the locations of candidate base stations. The base station specific search is then performed in the vicinities of those peaks by using base station specific pseudo-noise sequences. With this two stage cell search, the searching window is drastically reduced. The preamble is matched to known values by a respective receiver to decode the signals and permit multiple signals to be transferred from the transmitter to the receiver. The preamble may comprise two parts, Preamble-1 and Preamble-2, which may be used in different systems, including multioutput, multi-input (MIMO) systems.

  • Publication number: 20200328923
    Abstract: A method and apparatus for improving channel estimation within an OFDM communication system. Channel estimation in OFDM is usually performed with the aid of pilot symbols. The pilot symbols are typically spaced in time and frequency. The set of frequencies and times at which pilot symbols are inserted is referred to as a pilot pattern. In some cases, the pilot pattern is a diagonal-shaped lattice, either regular or irregular. The method first interpolates in the direction of larger coherence (time or frequency). Using these measurements, the density of pilot symbols in the direction of faster change will be increased thereby improving channel estimation without increasing overhead. As such, the results of the first interpolating step can then be used to assist the interpolation in the dimension of smaller coherence (time or frequency).

  • Publication number: 20200328944
    Abstract: Systems and methods are provided for identifying an available infrastructure network topology consisting of a set of available network links and a set of available network nodes of a communication network. In the systems and methods, a network node of the communication network is operative to transmit a learning schedule to a plurality of network nodes interconnected by a set of network links of the communication network. The network node receives from each of the plurality of network nodes a communication node record including network performance observations observed by that network node based on the learning schedule transmitted to that network node. Based on the received communication node records, the network node identifies a set of available network links from the set of network links and the set of available network nodes corresponding to the set of available network links.
