Abstract
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.
Claims11
A method of operation of a User Equipment (UE) in a wireless network to perform System Frame Number (SFN) Frame Time Difference (SFTD) measurements between a Primary Cell (PCell) of the UE and one or more other cells, the method comprising:
- receiving a Radio Resource Control (RRC) message from a network node in the wireless network, the RRC message specifying a list of cells;
- performing SFTD measurements between the PCell and the cells included in the list of cells;
- and
- reporting, to the network node, the SFTD measurements when no NR cell is determined to be configured as a Primary Secondary Cell (PSCell) of the UE.
A User Equipment (UE) for performing System Frame Number (SFN) Frame Time Difference (SFTD) measurements between a Primary Cell (PCell) of the UE and one or more other cells in a wireless network, the UE comprising:
- an interface comprising radio front-end circuitry;
- and
- processing circuitry associated with the interface, the processing circuitry configured to cause the UE to:
- receive a Radio Resource Control (RRC) message from a network node in the wireless network, the RRC message specifying a list of cells;
- perform SFTD measurements between the PCell and the cells included in the list of cells;
- and
- report, to the network node, the SFTD measurements when no NR cell is determined to be configured as a Primary Secondary Cell (PSCell) of the UE.
A method of operation of a User Equipment (UE) in a wireless network to perform System Frame Number (SFN) Frame Time Difference (SFTD) measurements between a Primary Cell (PCell) of the UE and one or more other cells, wherein the PCell is a Long Term Evolution (LTE) cell, the method comprising:
- receiving a Radio Resource Control (RRC) message from a network node in the wireless network, the RRC message specifying a list of cells, wherein the list of cells comprises one or more New Radio (NR) cells, wherein the list of cells is associated to Automatic Neighbor Relation (ANR) for Non-Standalone (NSA) NR;
- performing SFTD measurements between the PCell of the UE and a second cell, the second cell being a cell in the list of cells for which the UE can report SFTD measurements;
- and
- reporting, to the network node, the SFTD measurements in accordance with the list of cells for which the UE can report SFTD measurements.
