Methods, systems, apparatus, and computer programs, for selecting radio link control (RLC) entities to transmit packet data convergence protocol (PDCP) control protocol data unit (PDU). In one aspect, the method includes actions of accessing, by a device in a wireless communication system, data representing an index of RLC entities of a data radio bearer (DRB)/PDCP entity and RLC activation state information, the activation state information indicating whether one or more RLC entities of the DRB/PDCP entity in the index of RLC entities is activated or deactivated, selecting, by the device in the wireless communication system, a subset of the RLC entities of the DRB/PDCP entity based on an index position in the index and the activation state information for each of the RLC entities, and using the selected subset of RLC entities of the DRB/PDCP entity to transmit the PDCP Control PDU.

PDCP duplication enhancements

A process for execution by user equipment (UE) for activation or deactivation of a Radio Link Control (RLC) entity for Packet Data Convergence Protocol (PDCP) duplication includes identifying a set of RLC entities that are configured by a Radio Resource Control (RRC) for communication using PDCP. The process includes, for each RLC entity of the set of RLC entities: determining a network configured offset value; determining a channel condition value; and determining an RLC entity level value based on a combination of the network configured offset value and the channel condition value. The process includes comparing the RLC entity level value for each RLC entity to a threshold value; and based on comparing the RLC entity level value to the threshold value, selecting a subset of RLC entities for PDCP duplication; and activating or deactivating PDCP duplication for the selected subset of RLC entities.

User equipment based packet data convergence protocol (PDCP) duplication activation and deactivation

Disclosed are methods, systems, apparatus, and computer programs for compressing an Ethernet packet. In one aspect, a method involves mapping a portion of the Ethernet packet to a connection identity to compress the Ethernet packet. Additionally, the method involves encoding, in a user plane protocol stack layer, the connection identity in a data structure for transmission.
