Abstract
Methods and apparatuses are provided for controlling a communication device. A first subframe is received from a serving cell and a plurality of subframes is received from a plurality of neighbor cells. A respective time difference of arrival (TDOA) is measured for each of the plurality of subframes based on a time of arrival (TOA) of the first subframe. At least one of the measured TDOAs is transmitted to a location server. The respective TDOAs are measured based on at least one of a cell-specific reference signal (CRS) and a synchronization signal in the plurality of subframes.
