Abstract
Aspects of the present disclosure provided techniques for wireless communications by a user equipment (UE). An exemplary method, performed by the UE, generally includes identifying a level of coverage enhancement (CE) for the UE to communicate on at least one narrowband region within a wider system bandwidth in which the UE communicates with a base station (BS) and taking one or more actions to alter one or more procedures related to mobility of the UE, based on the level of CE.
Claims15
A method for wireless communications by user equipment (UE), comprising:
- identifying a first level of coverage enhancement (CE) for the UE to communicate on at least one narrowband region within a wider system bandwidth in which the UE communicates with a base station (BS);
- determining to move to a second level of CE;
- indicating to the BS to move to the second level of CE;
- taking action to cause a reconfiguration timer to be adjusted based on the indication to the second level of CE;
- starting the reconfiguration timer upon the indicating to the BS;
- and
- declaring a radio link failure (RLF) when a reconfiguration message is not received from the BS before expiration of the reconfiguration timer.
An apparatus for wireless communications by user equipment (UE), comprising:
- at least one processor configured to:
- identify a first level of coverage enhancement (CE) for the UE to communicate on at least one narrowband region within a wider system bandwidth in which the UE communicates with a base station (BS);
- determine to move to a second level of CE;
- indicate to the BS to move to the second level of CE;
- take action to cause a reconfiguration timer to be adjusted based on the indication to the second level of CE;
- start the reconfiguration timer upon the indicating to the BS;
- and
- declare a radio link failure (RLF) when a reconfiguration message is not received from the BS before expiration of the reconfiguration timer;
- and
- a memory coupled with the at least one processor.
An apparatus for wireless communications by user equipment (UE), comprising:
- means for identifying a first level of coverage enhancement (CE) for the UE to communicate on at least one narrowband region within a wider system bandwidth in which the UE communicates with a base station (BS);
- means for determining to move to a second level of CE;
- means for indicating to the B S to move to the second level of CE;
- means for taking action to cause a reconfiguration timer to be adjusted based on the indication to the second level of CE;
- means for starting the reconfiguration timer upon the indicating to the BS;
- and
- means for declaring a radio link failure (RLF) when a reconfiguration message is not received from the BS before expiration of the reconfiguration timer.
A non-transitory computer-readable medium for wireless communication by a user equipment (UE), wherein the non-transitory computer-readable medium comprises instructions for:
- identifying a first level of coverage enhancement (CE) for the UE to communicate on at least one narrowband region within a wider system bandwidth in which the UE communicates with a base station (BS);
- determining to move to a second level of CE;
- indicating to the BS to move to the second level of CE;
- taking action to cause a reconfiguration timer to be adjusted based on the indication to the second level of CE;
- starting the reconfiguration timer upon the indicating to the BS;
- and
- declaring a radio link failure (RLF) when a reconfiguration message is not received from the BS before expiration of the reconfiguration timer.
