Abstract:
1. A method for time synchronizing a plurality of base stations in a wireless communication system, comprising: sending a synch burst from at least one mastercell, wherein the mastercell has a better time synchronization quality than other cells; for at least one cell other than the mastercell, measuring a synch burst from at least the mastercell and indicating a timing associated with the synch burst to a radio network controller (RNC), wherein the measuring further comprises sending, by the RNC, a request for a base station time of arrival (BSTOA) value to a cell other than the mastercell, and transmitting the BSTOA value; and sending, by the RNC, a timing adjustment to the at least one cell other than the mastercell.
