Title:
TECHNIQUES FOR IMPROVING RANDOM ACCESS PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2021/248306
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure provide techniques for multi-random access operations. A method that may be performed by a user equipment (UE) includes determining that a first random access procedure is triggered while a second random access procedure is ongoing, the first random access procedure and the second random access procedure being associated with different contention resolution types, generating a random access message including a common control channel (CCCH) and a cell-radio network temporary identifier (C-RNTI) medium access control (MAC) -control element (CE), based on the determination, and transmitting the random access message to the base station.
