PACKET DATA CONVERGENCE PROTOCOL (PDCP) DUPLICATION ENHANCEMENTS

Abstract:

Aspects of the present disclosure relate to wireless communications, and more particularly to techniques for enhancing packet data convergence protocol (PDCP) duplication, for example, by allowing a user equipment (UE) to autonomously activate/deactivate (uplink (UL)) PDCP duplication. A method that may be performed by a UE includes detecting one or more events related to channel conditions and activating PDCP duplication at the UE in response to the detection. In some cases, the UE may provide a network entity an indication of the PDCP duplication activation/deactivation. In response to the indication, the network entity may, for example, activate/deactivate downlink (DL) PDCP duplication.
