Title:
RESTORATION OF DATA CONNECTIVITY AFTER RANDOM ACCESS PROBLEM IN NON-STANDALONE NETWORK
Document Type and Number:
WIPO Patent Application WO/2021/226859
Kind Code:
A1
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, while registered with a non-standalone network, that a count of random access failures for a cell satisfies a failure count threshold, based at least in part on adding a secondary cell group. The UE may perform a detach and attach procedure or a tracking area update procedure with the cell based at least in part, on the determining that the count of random access failures satisfies the failure count threshold. Numerous other aspects are provided.
