  • Patent number: 10631198
    Abstract: Systems and methods are described herein for identifying areas of maximum congestion so that small cells can be deployed at those specific sites to obviate network congestion problems. The systems and methods identify several input sources (e.g., call data records, passively collected data using Mobile app, etc.) that can be used to identify data congestion. The systems and methods divide a particular geographic area into smaller tiles of a certain shape (e.g., hexagon, square, etc.). For each of the geographic tiles, the systems and methods sort and group the input data samples based on their associated congestion discriminating characteristics (e.g., timestamps, type of input data, etc.). The systems and methods then compute a congestion index for each geographic tile area based on the grouped data samples. In this manner, the systems and methods identify geographic tile areas and time periods of high congestion.

  • Patent number: 9769835
    Abstract: Network-side and device-side methods and apparatuses improve transmit link adaptation for devices operating in a cellular network that have interference-canceling receivers. Own-cell link adaptation towards a device in a current transmission interval exploits a determined mapping between the interfering-signal cancelation efficiency of the device versus the interfering-signal transport format, in combination with actual knowledge of the transport format that will be used to make an interfering neighbor-cell transmission in the current transmission interval. For example, a serving radio node uses the known transport format of the interfering transmission, to accurately determine the expected cancellation efficiency for the device with respect to the interfering transmission, and uses the expected cancellation efficiency to obtain a more accurate estimate of the own-cell channel quality expected for the device in the current transmission interval.

  • Patent number: 9755785
    Abstract: Techniques for detecting and demodulating a signal/transmission are described. Signal detection is performed in multiple stages using different types of signal processing, e.g., using time-domain correlation for a first stage, frequency-domain processing for a second stage, and time-domain processing for a third stage. For the first stage, products of symbols are generated for at least two different delays, correlation between the products for each delay and known values is performed, and correlation results for all delays are combined and used to declare the presence of a signal. For demodulation, the timing of input samples is adjusted to obtain timing-adjusted samples. A frequency offset is estimated and removed from the timing-adjusted samples to obtain frequency-corrected samples, which are processed with a channel estimate to obtain detected symbols. The phases of the detected symbols are corrected to obtain phase-corrected symbols, which are demodulated, deinterleaved, and decoded.
