Summary:A configuration to adjust expiration of a PDCP reorder timer based on scheduler variations in dual connectivity. The apparatus receives, from a base station, a plurality of data packets. The plurality of data packets received from a first path and a second path. The apparatus detects at least one packet of the plurality of data packets at a PDCP is dropped based on an OOW. The apparatus determines a scheduling gap between the first path and the second path. The apparatus determines a timing relationship between the UE, the first path, and the second path. The apparatus determines consecutive sequence numbers associated with packets corresponding to the frame numbering sequence of the first path and the frame numbering sequence of the second path and a respective associated time. The apparatus adjusts a reorder timer based on the scheduling gap between the first path and the second path.
