| 20160381563 | LOW INTERFERENCE CELLULAR DATA COMMNUNICATION IN UNLICENSED FREQUENCY SPECTRUM - A cellular base station communicates data using both the licensed and unlicensed frequency spectrums. For each interval of a set of intervals (such as intervals corresponding to communication of LTE frames), the base station first identifies whether signaling is detected on a specified unlicensed frequency channel (UFC). If a signal is detected, the base station communicates data only over a licensed frequency channel (LFC) for the interval, and does not employ the UFC for the interval. If no signal is detected, the base station communicates data over the interval on both the LFC and the UFC. To ensure that other devices have the opportunity to use the UFC in a timely fashion, the base station communicates data over the UFC for only a portion of the interval. | 12-29-2016 |
| 20160381564 | Cellular Communications Spectrum Management - The techniques described herein enable a commercial cellular service provider to use a repurposed portion of spectrum to provide cellular service to a customer base while ensuring that the use of the repurposed portion of spectrum does not interfere with a previous use of the repurposed portion of spectrum by an incumbent entity. The techniques determine, and manage the use of, forbidden cells and clean cells. A “forbidden” cell is a cell in which a previous use of spectrum by an incumbent entity is protected. A “clean” cell is a cell that can be freely used by the commercial cellular service provider without a possibility of interference with a protected use of the spectrum by the incumbent entity. | 12-29-2016 |
