Publication number: 20240080738Abstract: 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.Type: ApplicationFiled: April 1, 2021Publication date: March 7, 2024Inventors: Muralidharan MURUGAN, Nitin PANT, Jun DENG, Rishika TINDOLA, Sham Sunder KANTAYAPALEM, Uttam VYAS
