PDCP STATUS REPORTS USING SEQUENCE NUMBERS OR SEQUENCE NUMBER OFFSETS
First Claim
1. A communication device comprising circuitry to:
- receive packets, corresponding to a single radio bearer, from network devices corresponding to distinct radio access technologies (RATs);
identify, based on the packets, sequence numbers (SNs) of missed packets that were not received by the device;
create, based on the SNs, a report that identifies the missed packets; and
communicate the report to one of the network devices.

Abstract
A user equipment device (UE) may create efficient Packet Data Convergence Protocol (PDCP) status reports. The UE may receive PDCP packets from multiple radio access technologies (RATs) using the same bearer or same RAT using split bearers. The UE may identify packets that the UE should have received but did not, and may create a status report based on the sequence numbers (SNs) of the packets that the UE failed to receive or based on the SNs of the successful packets. The report may include the SNs of the packets, in addition to a bit-length of the SNs and/or a starting point of the SNs in the status report. Alternatively, the report may include the SN of a first packet that the UE failed to receive and offset values (relative to the SN of the first packet) for the other packets that the UE failed/succeed to receive.
