Abstract: Apparatus, methods, and computer-readable media for facilitating handling of voice over service fallback are disclosed herein. An example method for wireless communication at a UE includes initiating a TAU procedure when performing a change from a first cell associated with a first RAT to connect to a second cell associated with a second RAT different than the first RAT. The example method also includes initiating a timer when the TAU procedure fails, the timer associated with a first duration. The example method also includes re-initiating the TAU procedure based on an occurrence of a timer modification event, the re-initiating of the TAU procedure occurring before the first duration associated with the timer expires.

Abstract: Methods and mechanisms for performing idle mode mobility procedures are provided. According to one aspect of the present disclosure, a method for wireless communication performed by a user equipment (UE) includes: receiving, from a base station (BS) on a first cell, system information indicating a first cell reselection priority configuration; receiving, from the BS, dedicated signaling indicating a dedicated cell reselection priority configuration, wherein the dedicated cell reselection priority configuration is empty; and connecting, while in an idle mode and in response to the dedicated cell reselection priority configuration being empty, to a second cell different from the first cell based on the first cell reselection priority configuration received in the system information.
