Method for reporting a radio link problem and a device therefor
First Claim
Patent Images
1. A method performed by a user equipment (UE) supporting dual connectivity in a wireless communication system, the method comprising:
- detecting a radio link problem associated with a secondary base station (BS) that is associated with a first cell and at least one second cell, wherein the first cell supports contention-based random access;
determining whether the first cell or the at least one second cell has the radio link problem; and
reporting the radio link problem to a master BS based on a determination that the first cell has the radio link problem,wherein the UE includes two medium access control (MAC) entities;
a first MAC entity for the master BS and a second MAC entity for the secondary BS.

Abstract
A method is provided for operating by a user equipment (UE) connected with a master base station (BS) and a secondary BS in a wireless communication system. The UE configures a first cell supporting a contention based random access and a second cell other than the first cell. The first cell and the second cell are associated with the secondary BS. The UE determines whether a radio link problem is occurred on the first cell or the second cell. The UE indicates the radio link problem to an upper layer only if the radio link problem occurs on the first cell.

11. A user equipment (UE) configured to support dual connectivity in a wireless communication system, the UE comprising:
-
a transceiver; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising; detecting a radio link problem associated with a secondary base station (BS) that is associated with a first cell and at least one second cell, wherein the first cell supports contention-based random access; determining whether the first cell or the at least one second cell has the radio link problem; and reporting, via the transceiver, the radio link problem to a master BS based on a determination that the first cell has the radio link problem, and wherein the UE includes two medium access control (MAC) entities;
a first MAC entity for the master BS and a second MAC entity for the secondary BS. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
