Abstract
Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a first operational layer of the receiving device, one or more protocol data units (PDUs) within a set of PDUs. The receiving device may identify, at a second operational layer of the receiving device, a sequence gap associated with a missing PDU from the set of PDUs, the first operational layer being a lower operational layer of the receiving device than the second operational layer. The receiving device may determine, at the second operational layer, that a triggering condition associated with the missing PDU has occurred. The receiving device may provide, by the second operational layer and based at least in part on the triggering condition occurring, an indication to update a reception buffer of the first operational layer to a last received protocol data unit of the set of PDUs.
