1. A method for wireless communications with lower level Hybrid Automatic Repeat-Request (HARQ) transmissions, comprising:
- receiving a lower level HARQ data burst including at least one protocol data unit (PDU), each PDU having a sequence number;
transmitting a HARQ negative acknowledge (NAK) message for prompting a retransmission of the lower level HARQ data burst when at least one PDU is not successfully received; and
receiving, after a maximum number of lower level HARQ retransmissions has been reached for the data burst including the at least one PDU that was not successfully received, a PDU header indicating a sequence number for the at least one PDU that should not be expected because the maximum number of lower level HARQ retransmissions has been reached.

Abstract
Embodiments of the present disclosure allow a HARQ transmitter to provide a receiver an indication of the protocol data units (PDUs) that should not be expected because they are part of a data burst that has been retransmitted a maximum allowable number of times. The indication message may contain a maximum serial number contained in the data burst that has reached the maximum number of retransmissions, or the serial number of a first PDU in the next data burst.
