In-sequence reception of pdus in a pdu set in the downlink and triggering of recovery of missing pdus

Abstract

A wireless transmit/receive unit (WTRU) may include one or more processors. The WTRU may be configured to receive configuration information indicating a threshold value associated with a protocol data unit (PDU) set error rate (PSER), receive a first plurality of packet data units (PDUs) of a first PDU set, determine that at least one PDU of the first PDU set is missing, receive a second plurality of PDUs of a second PDU set, determine a PSER value based on a number of high priority PDUs received in the first plurality of PDUs and the second plurality of PDUs, and/or transmit an indication of the at least one PDU of the PDU set that is missing on condition that the determined PSER value is greater than the threshold value indicated in the configuration information.
