Abstract
An unsynchronized base site (,) transmits a time synchronization request to a communication unit (,). A time synchronization error, or a timing offset, for the unsynchronized base site (,) is then determined and transmitted back to the unsynchronized base site (,) to enable the unsynchronized base site to synchronize itself. The time synchronization error is determined for the unsynchronized base site (,) based on the time difference of arrival of the signals received by the communication unit (,) from the base site (,) and at least one synchronized base site (,), the location of the communication unit (,), the location of the base site (,), and the location of the at least one synchronized base site (,).
