摘要： A first base station synchronizes with one or more second base stations by transmitting, from the first base station, a first timing reference signal and receiving, at the first base station, one or more second timing reference signals transmitted by the one or more second base stations. The method also includes determining one or more first timing offsets between the first base station and the one or more second base stations based on the one or more second timing reference signals. The method further includes adjusting a timing associated with the first base station based on the one or more first timing offsets and one or more second timing offsets determined based on the first timing reference signal.

摘要： Methods and systems for determining a location of a UE includes receiving UE position information from a UE being serviced by a plurality of base stations. The UE position information may include a signal reception time and a signal transmission time or a timing advance for at least two of the plurality of base stations. The signal transmission time being a measured time for a signal being transmitted by the UE to be received by a base station, the signal reception time being a measured time for a signal being transmitted by the base station to be received by the UE, and the timing advance being a difference between the signal transmission time and the signal reception time for the base station. The method may include determining a location of the UE based on the received UE position information.

摘要： In one example embodiment, the method includes determining, by a first device, a timing of a primary synchronization signal and a secondary synchronization signal to be transmitted by a second device, determining, by the first device, a timing of a measurement gap for a user equipment served by the first device, the measurement gap being a period of time during which the user equipment searches for the primary and secondary synchronization signals from the second device, and instructing, by the first device, the user equipment to search for the primary and secondary synchronization signals from the second device at the determined timing of the measurement gap.

摘要： A user equipment measures a time difference of arrival of a plurality of signals received at the user equipment, wherein at least one of the plurality of signals is received at the user equipment on at least one unlicensed band. The user equipment then reports the time difference of arrival measurements for the plurality of signals to a location computation center along with a time stamp for each of the measurements. The location computation center then determines the location of the user equipment based on the reported time difference of arrival measurements.
