Abstract
Two or more base stations may share relative timing information. For example, a first cell may determining a cell level system frame number (SFN) and frame timing difference (SFTD) between the first cell and a second cell. At least one user equipment (UE) can be configured with dual connectivity with the first cell and the second cell. The first cell may send an indication of the cell level SFTD to the second cell via a backhaul with the second cell. The indication of the cell level SFTD may be the determined SFTD or a SFN reference time. In some implementations, the first cell may send a the SFTD measurement result and assistance information to the second cell via a backhaul to the second cell. The second cell may determine the cell level SFTD. In some implementations, a positioning network entity may determine the cell level SFTD.
