Synchronizing radio units in a main-remote radio base station and in a hybrid radio base station

摘要: A main-remote radio base station system includes plural remote units each having a digital interface unit and main unit. Different length links couple different to the The interfaces in include data channel timing channel. delay associated with link is determined without interrupting transmission of over delays, reported continuously, periodically, or upon request, are compensated for equalized by advancing time when signals sent their respective channels. In preferred embodiment, optical interface. hybrid synchronized “near” “remote” units.
