Abstract:
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.
