Title: Data discard for radio link control in wireless networks
Inventor: MEYLAN ARNAUD
IPC: H04L1/18
Filed: 2008-09-17
Abstract: Systems and methodologies are described that facilitate in-band notification of stale service data units (SDU) in a radio link control (RLC) layer for wireless communications. In particular, where SDUs become stale during protocol data unit (PDU) retransmission, in-band notifications can be packed in retransmit PDUs for receipt and interpretation by a receiver. The in-band notification can be a special length indicator that specifies discard of an SDU that was previously partially received, and the transmitter of the PDU can save payload by not retransmitting the stale SDU. In this regard, additional channels, mediums, and/or other out-of-band notifications are not required to specify discard.
