NR RRC connection setup optimisation

Abstract:

Systems and methods of optimizing NR RRC connection establishment are described. The UE transmits a RRC request for establishment of a connection to a gNB. The RRC request is transmitting on a SRB1 rather than SRB0. The SRB1 has a default SRB1 configuration stored in memory. A response from the gNB is received and acknowledged using the SRB1 or a SRB1 having a SRB1 configuration provided in the response. The RRC request is a RRCReestablishmentRequest or RRCResumeRequest.
