Abstract: Systems and methods are provided for providing blind fast network synchronization for reducing LTE public safety products costs, comprising, in one embodiment: determining if location setup is required to mitigate timing offset due to propagation delay from the synchronization source and adjusting downlink timing, and when location setup is required then providing one of manual setup in terms of timing samples, limited power RACH based on SIB2 parameters, and based on observed time difference of arrival and position reference signal; coordinating network listening periods based on graphs and hash function to avoid common silence for two or more neighboring eNodeBs; and providing continuous synchronization using blind carrier estimation.

Abstract: Coordinated signal processing at at least a first and second transceiver integrated circuit (IC) configured to commonly process aggregated signal-port IQ data packets; and, each transceiver IC having a transmit signal processing circuit configured to process the commonly-processed aggregated signal-port IQ data packets in accordance with frequency-specific beam-tilt information received in control message packets. The frequency-specific electronic beam tilt may be applied to either a designated component carrier, or to a designated subset of subcarriers within a given component carrier.
