Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.
Claims20
A method of wireless communication performed by a user equipment (UE), comprising:
- detecting that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS;
- selectively maintaining, based at least in part on detecting that the timer has expired prior to completing the handover and whether a connection between the UE and the source BS satisfies a connection condition, the connection,
- wherein the UE maintains the connection without an action associated with a radio link failure being performed based at least in part on the timer having expired prior to completing the handover and the connection satisfying the connection condition;
- and transmitting, to the source BS, a message when the connection is maintained.
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, which are configured, individually or in any combination, to:
- detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS;
- selectively maintain, based at least in part on detecting that the timer has expired prior to completing the handover and whether a connection between the UE and the source BS satisfies a connection condition, the connection,
- wherein the UE is configured to maintain the connection without an action associated with a radio link failure being performed based at least in part on the timer having expired prior to completing the handover and the connection satisfying the connection condition;
- and
- transmit, to the source BS, a message when the connection is maintained.
An apparatus for wireless communication, comprising:
- means for detecting that a timer has expired prior to completing a handover of the apparatus from a source base station (BS) to a target BS;
- means for selectively maintaining, based at least in part on detecting that the timer has expired prior to completing the handover and whether a connection between the apparatus and the source BS satisfies a connection condition, the connection,
- wherein the apparatus maintains the connection without an action associated with a radio link failure being performed based at least in part on the timer having expired prior to completing the handover and the connection satisfying the connection condition;
- and
- means for transmitting, to the source BS, a message when the connection is maintained.
