1. A wireless communication device, comprising:
one or more memories;
one or more processors in communication with the one or more memories, wherein the one or more processors are individually or collectively configured to cause the device to:
determine a packet data convergence protocol (PDCP) packet count corresponding to a last radio link control (RLC) packet received in-sequence;
detect a missing PDCP packet based on a comparison of the PDCP packet count and a sequence number of a last PDCP packet received in-sequence;
establish communication with a first bearer and a second bearer, wherein the PDCP packet count is associated with the first bearer; and
determine a second PDCP packet count corresponding to a second last RLC packet received in-sequence that is associated with the second bearer, wherein the detection of the missing PDCP packet is further based on a second comparison of the second PDCP packet count and the sequence number.
