Abstract

Transmitters consider the size of a gap segment adjacent to at least one negatively acknowledged (NACKed) Radio Link Control (RLC) Service Data Unit (SDU) when considering when and/or how to concatenate one or more NACKed SDU segments for retransmission. Depending on which RLC SDU segment(s) is/are NACKed, e.g., considering the size of NACKed segments in relation to Protocol Data Unit (PDU) header size(s) needed, the transmitter implements a single RLC SDU retransmission or multiple RLC SDU segment retransmissions. In so doing, the solution presented herein not only defines how such transmissions occur, but also provides improved efficiency when retransmitting such NACKed SDU segments.
