Publication number: 20220408311Abstract: Systems and methods are disclosed herein that enable a wireless communication device (WCD) and/or a network node to perform a recovery action(s) when a failure occurs during reception, at the WCD, of a segmented Radio Resource Control (RRC) message. Embodiments of a method performed by a WCD are disclosed. In one embodiment, a method performed by a WCD comprises receiving one or more segments of a segmented RRC message and determining that an error has occurred before a last segment of the segmented RRC message has been received. The method further comprises, upon determining that the error has occurred before the last segment of the segmented RRC message has been received, performing one or more recovery actions. In this manner, a situation where the WCD combines segments of a first RRC message with segments of a second RRC message is avoided and, hence, errors due to such combining are avoided.Type: ApplicationFiled: September 17, 2020Publication date: December 22, 2022Inventors: Mattias Bergstrom, Malik Wahaj Arshad
