Published: with international search report (Art. 21(3)) (54) Title: PACKET DUPLICATION AT A PACKET DATA CONVERGENCE PROTOCOL (PDCP) ENTITY (57) : Techniques are described for operating procedures associated with packet duplication. A packet data protocol convergence protocol (PDCP) entity of a transmit- ting device may duplicate a received packet to form a set of copied packets. Each packet in the set of copied packets may include the information of the received packet. Each packet of the set of copied packets may be transmitted using a different radio link control 0 (RLC) entity. Procedures are described for configuring duplication bearers. Procedures are described for activating or deactivating packet duplication. Procedures are described for handling RLC entities at deactivation. Procedures are described for discarding some duplicate packets after a packet has been successfully decoded by a receiving device. Procedures are described for delaying transmission of duplicate packets to improve effi- FIG. 3A , 05 cient use of communication resources. Procedures are described for buffer status report (BSR) reporting for duplication bearers.
