TECHNIQUES AND APPARATUSES FOR 5G TO 2G/3G FALLBACK WITHOUT ACCESSING AN LTE AIR INTERFACE

摘要

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a 4G/LTE device and via a 5G/NR base station, a first handover command message identifying at least one of a measurement configuration or a measurement gap for identifying a 2G/3G cell, wherein the first handover command message is associated with a 5G/NR to 2G/3G handover of the UE via 4G/LTE; transmit, to the 4G/LTE device and via the 5G/NR base station, a measurement report regarding the 2G/3G cell based at least in part on the measurement configuration and/or the measurement gap; and tune to the 2G/3G cell based at least in part on a second handover message, received from the 4G/LTE device via the 5G/NR base station, for performance of the call via the 2G/3G cell. Numerous other aspects are provided.
