Abstract: Techniques for recovering quickly from a radio link failure (RLF) by identifying potentially strong candidate cells, while avoiding the conventional delays from relying only on initial ACQ DB scans followed by band-scanning, are disclosed. In one aspect, a wireless apparatus such as a user equipment (UE) may identify a radio link failure (RLF) of an existing wireless connection. The UE may prioritize, during an RLF recovery procedure for restoring the connection, candidate cells using connection criteria from one or more measurement reports. The UE can thereupon restore the connection using a cell having a highest priority. In various configurations, the UE can use cells from A3, A4, A5, inter-RAT or periodic measurement reports to reestablish a stronger connection in a faster time.

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.
