  • Handling of PDCP version during RRC connection re-establishment procedure
    Patent number: 12256455
    Abstract: Systems, methods, and apparatus are disclosed for a user equipment. An example method performed by a user equipment includes establishing a connection to a Radio Access Network (RAN) via a first network node. Communications are provided over the connection using Signaling Radio Bearer 1 (SRB1) configured with a New Radio (NR) Packet Data Convergence Protocol (PDCP). After the connection is suspended, the user equipment receives a Radio Resource Control (RRC) connection re-establishment message from a second network node. The connection re-establishment message includes a radioResourceConfigDedicated information element (IE). The user equipment re-establishes the connection to the RAN by applying a Long-Term Evolution (LTE) PDCP configuration to SRB1, performing a radio resource configuration procedure in accordance with the radioResourceConfigDedicated IE, and sending an RRC connection re-establishment complete message to the second network node.
