Abstract
An apparatus for adapting hyper cells in response to changing conditions of a cellular network is disclosed. During operation, the apparatus collects data regarding network conditions of the cellular network. In accordance with the collected network condition data, the apparatus changes an association of a transmit point from a second cell ID of a second hyper cell to a first cell ID of a first hyper cell. Virtual data channels, broadcast common control channel and virtual dedicated control channel, transmit point optimization, UE-centric channel sounding and measurement, and single frequency network synchronization are also disclosed.
