Abstract

In a heterogeneous network deployment that includes a macro base station and a low power node, a geometry indicator is transmitted by the low power node to facilitate the calculation of a path loss difference value at a user equipment using power estimates of the received synchronization signal from the macro base station and received geometry indicator signal from the low power node. Using the estimated path loss difference value, the user equipment adjusts the power level of an initial preamble signal transmission to the macro base station.
