Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method for handling segmentation in a converged layer 2 (L2) communication network is provided. The method includes assigning, by a converged L2 of a transmitter, a L2 sequence number (SN) to a protocol data unit (PDU). The L2 SN includes at least one of a last segment indication (LSI) indicating a presence of a last service data units (SDU) of the complete PDU, a length indicator exist (LIE) indicating a presence of a length indicator (LI) after a L2 header, or a SI indicating a segmentation status or stage of the complete PDU, receiving, by a medium access control (MAC) layer of the transmitter, a grant opportunity or a transmission opportunity for transferring the PDU available at the converged L2, and sending the PDU to a lower layer of the transmitter for transmission to a receiver with or without segmentation based on the grant or a transmission opportunity.

Abstract: The present disclosure relates to a method performed by a user equipment (UE) for secondary node failure recovery in a non-standalone (NSA) communication system. The method comprises identifying failure in a secondary node, the UE being connected to a master node and the secondary node. The method comprises sending, to the master node, information related to the failure of the secondary node and an indication of a presence of a fallback secondary node configuration. The method comprises evaluating, an execution condition of the fallback secondary node based on a plurality of connection parameters. The method comprises sending to the master node, a Radio Resource Control (RRC) reconfiguration complete message to connect to the fallback secondary node based on that the evaluation condition is succeeded.

Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method of UE for camping on a network entity is provided. The method includes receiving, by the UE, an information block from one of one or more network entities, determining, by the UE, if the indicated capability of the network entity or the corresponding security level are compliant with capability and security level requirement of the UE for camping, and camping by the UE, on the network entity when the indicated capability or the corresponding security level supported by the network entity is determined to be compliant with the capability and the security level requirement of the UE using the compliant type of cryptography technique.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal for dynamic data encryption in a communication system is provided. The method includes receiving, from a network entity, a list of network public keys including a plurality of network public keys and corresponding key indexes, generating a pair of keys including a user equipment (UE) public key and a UE private key in response to receiving the list of network public keys, randomly selecting a network public key from the list of network public keys received from the network entity, generating a shared secret key corresponding to the UE by using the randomly selected network public key and the UE private key, and encrypting data to be transferred between the UE and the network entity by using the generated shared secret key corresponding to the UE.

Abstract: A method for processing at least one Internet Protocol (IP) packet performed by a converged layer 2 (L2) in a wireless communication system is provided. The method includes receiving, by the converged L2, at least one internet protocol (IP) packet as a service data unit (SDU) from an IP layer, assigning, by the converged L2, a sequence number to the received at least one IP packet, adding, by the converged L2, at least one L2 header to the received at least one IP packet to process a protocol data unit (PDU), and transmitting, by the converged L2, the processed at least one PDU to at least one medium access control (MAC) lower layer.
