SFTD and ANR specific reporting
Systems and methods for System Frame Number (SFN) Frame Time Difference (SFTD) reporting are disclosed. Embodiments of a method of operation of a User Equipment (UE) in a wireless network to perform SFTD measurements between a Primary Cell (PCell) of the UE and one or more other cells is provided. In some embodiments, the method comprises receiving, from a network node in the wireless network, a list of cells for which the UE can report SFTD measurements. The method further comprises performing SFTD measurements and reporting the SFTD measurements in accordance with the list of cells for which the UE can report SFTD measurements. In this manner, SFTD reporting is provided in an efficient manner.

receiving an RRCConnectionResume message or an RRCConnectionReconfiguration message from a network node in the wireless network, the RRCConnectionResume message or the RRCConnectionReconfiguration message comprising a list of cells, wherein the list of cells comprises one or more New Radio (NR) cells;
determining the RRCConnectionResume message or the RRCConnectionReconfiguration message comprises an indication to perform SFTD measurements between the PCell and one or more NR neighbor cells;
based on the determination, performing SFTD measurements between the PCell and the one or more NR cells included in the list of cells; and
reporting, to the network node, the SFTD measurements in accordance with the list of cells for which the UE can report SFTD measurements.
2. The method of claim 1 , further comprising determining no NR cell is configured as a Primary Secondary Cell (PSCell) of the UE.
3. The method of claim 1 , further comprising determining the RRCConnectionResume message or the RRCConnectionReconfiguration message comprises a second field that specifies whether a PSCell is applicable.
4. The method of claim 3 , wherein the determining the RRCConnectionResume message or the RRCConnectionReconfiguration message comprises the indication to perform SFTD measurements between the PCell and one or more NR neighbor cells is in response to the PSCell not being applicable.
5. The method of claim 1 , wherein the RRCConnectionResume message or the RRCConnectionReconfiguration message further specifies whether the one or more NR neighbor cells are applicable.
6. The method of claim 5 , wherein the reporting the SFTD measurements is in response to the one or more NR neighbor cells being applicable.
7. The method of claim 1 , wherein the list of cells is specified by a field in a configuration report information element.
8. The method of claim 1 , wherein the PCell comprises a NR cell.
9. The method of claim 1 , wherein the PCell comprises a Long Term Evolution (LTE) cell.
