  • Publication number: 20200329472
    Abstract: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

  • 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.
