Abstract: Disclosed is a system and methods for creating and maintaining a virtual subnetwork of telecommunication base stations within a wider telecommunication network. In an LTE-based example, the subnetwork includes a connection aggregator that is coupled between the plurality of eNodeBs internal to the subnetwork and one or more MMEs in the outer network. The connection aggregator intercepts all control plane messages between the MMEs and the internal eNodeBs, remaps eNodeB identifiers, and transmits repackaged messages so that the outer network sees the entire subnetwork as a single “giant” eNodeB. The disclosed system and methods enables the operator of the virtual subnetwork to add and shut down eNodeBs as demand for connectivity fluctuates, and to do so such that all changes are unseen by the outer network.

Abstract: A wireless telecommunications base station that compensates for Doppler shift in each connected User Equipment. The base station deploys a plurality of parallel receivers, each with a given frequency offset above and below the carrier frequency. Each receiver performs a frequency shift on a common uplink signal, determines the quality of the frequency shifted uplink signal, and demodulates the frequency shifted uplink signal. A selector/combiner module generates a highest quality demodulated signal, which may be done by selecting the frequency shifted uplink signal or soft combining a subset of frequency shifted uplink signals having a sufficiently high quality.

Abstract: A distributed radio system has one or more distributed radio processors that processes analog RF signals from a plurality of legacy base station transceivers (BTSs) as well as packetized digital mid-haul data (such as 7.2x data packets) from one or more baseband units.

The digital signals are summed and transmitted to one or more remote units. For the uplink, the process is reversed. A supervisor module provides the offset frequencies to the relevant digital baseband signals.
