  • Patent number: 10271267
    Abstract: Systems and methodologies are described that facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment. For instance, relative locations of a PSC and a SSC in a radio frame can be a function of a parameter. Further, a PSC sequence utilized to generate PSCs can be selected based upon a parameter. Moreover, inclusion or exclusion of PSCs from a radio frame can be a function of a parameter. Additionally or alternatively, pseudo random sequence mappings (e.g., to cell IDs, tone locations) can be a function of a parameter. Example parameters can be whether the base station is part of a TDD or a FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or a femto cell, or whether the base station is associated with a unicast or a multicast system.

  • Patent number: 10136438
    Abstract: A wireless communication platform utilizes flexible bandwidth assignment to re-allocate bandwidth between spot beams. The platform may assign a first combination of frequency and polarization (FP) to a first spot beam and a second combination of frequency and polarization to a second spot beam that is adjacent and at least partially overlapping the first spot beam. The platform may assign to the first spot beam a reserved combination of frequency and polarization during a first time period, and at second time, assign the reserved combination to the second spot beam. The platform may also assign the reserved combination simultaneously to adjacent spot beams by managing user of the reserved combination by geographically isolated terminals in the spot beams. The platform may further assign different portions of the reserved combination to adjacent spot beams without geographical limitations.

  • Patent number: 10135579
    Abstract: Systems and methods presented herein provide for an eNodeB operating in an RF band comprising a conflicting wireless technology. One exemplary eNodeB assigns an ID to a UE, processes a scheduling request for UL data from the UE, processes another scheduling request for second UL data from the UE, determines priorities of the first and second UL data based on priority indicators in the scheduling requests, and grants time and frequency for the UE to transmit the first and second UL data. The eNodeB also waits until the UE performs an LBT operation. The LBT determines whether the granted time and frequency are occupied by another wireless system comprising a different wireless technology. The eNodeB also determines that the first UL data is stale, and transmits the ID to the UE to reserve the granted time and frequency for the second UL data when unoccupied by the other wireless system.
