Abstract
Radio link Failure (RLF) reporting operation in a wireless communication system using multiple cells is disclosed. According to this operation, when a first cell and a second cell are simultaneously connected to a UE and the first cell and the second cell are of different base stations (a first base station and a second base station respectively), if the RLF with the UE on the first cell is detected by the first base station, the first base station may transmits an indication of the RLF with the UE on the first cell to the second base station.
Claims12
A method for a first base station (BS) to operate in a wireless communication system, the method comprising:
- detecting, by a first secondary cell (SCell) of the first BS, a radio link failure (RLF) on the first SCell, while the first BS and a second BS having a primary cell (PCell) are simultaneously respectively connected with a user equipment (UE) through the first SCell and the PCell;
- and
- transmitting, by the first SCell of the first BS to the PCell of second BS, an indication of the RLF on the first SCell,
- wherein a second SCell is newly configured for the UE by the PCell of the second BS when the PCell of the second BS receives the indication.
A base station device for operating as a first base station (BS) in a wireless communication system, the device comprising:
- a transceiver configured to transmit or receive signals over the air;
- a processor electrically connected to the transceiver and configured to control the transceiver to:
- detect, by a first secondary cell (SCell) of the first BS, a radio link failure (RLF) on the first SCell, while the first BS and a second BS having a primary cell (PCell) are simultaneously respectively connected with a user equipment (UE) through the first SCell and the PCell;
- and
- transmit, by the first SCell of the first BS to the PCell of second BS, an indication of the RLF on the first SCell,
- wherein a second SCell is newly configured for the UE by the PCell of the second BS when the PCell of the second BS receives the indication.
