Abstract:
1. A method for wireless communication, comprising: detecting, while a user equipment (UE) is in a connected state with a serving cell with communication occurring on an uplink and a downlink, an instance of handover failure; storing, in response to detecting an instance of handover failure, the detected instance of handover failure together with at least one of the following related aspects in the UE in a UE log: a time of the handover failure, a cell ID associated with the handover failure, a communication mode associated with the handover failure, and a duration for which a user equipment camps on a cell with a cell ID associated with the handover failure; storing in the UE log, in response to detecting an instance of handover failure, information associated with at least one of a reference signal received power (RSRP) of the serving cell or a reference signal received quality (RSRQ) of the serving cell; and storing in the UE log, in response to detecting an instance of handover failure, a data rate used by the UE, wherein the UE log comprises the detected instance of handover failure and corresponding at least one related aspect, at least one RSRP information or RSRQ information, and data rate used by the UE.
