METHODS AND APPARATUSES FOR A MRO MECHANISM FOR A FAST MCG LINK RECOVERY PROCEDURE AND AN UNBALANCED UL AND DL COVERAGE SCENARIO

摘要

Embodiments of the present application relate to methods and apparatuses for a mobility robustness optimization (MRO) mechanism for a fast master cell group (MCG) link recovery procedure and an unbalanced uplink (UL) and downlink (DL) coverage scenario under a 3rd Generation Partnership Project (3GPP) 5G New Radio (NR) system or the like. According to an embodiment of the present application, a method can include: receiving configuration information regarding a fast master cell group (MCG) link recovery procedure for a user equipment (UE); in response to an occurrence of a radio link failure (RLF) on a MCG, performing the fast MCG link recovery procedure and starting a timer associated with fast MCG link recovery; storing information associated with the fast MCG link recovery procedure in response to successfully completing the fast MCG link recovery procedure or in response to failing to complete the fast MCG link recovery procedure; and in response to the UE accessing a base station (BS), reporting the stored information to the BS. In addition, a UE may report assistant information (e.g., transmitting power) to a BS. The BS may identify whether there is a problem in an uplink using the assistant information.
