<P>PROBLEM TO BE SOLVED: To facilitate in-band notification of stale service data units (SDUs) in a radio link control (RLC) layer for wireless communications. <P>SOLUTION: When SDUs become stale during protocol data unit (PDU) retransmission, in-band notifications are packed in retransmit PDUs for receipt and interpretation by a receiver. The in-band notification is a special length indicator that specifies discard of an SDU that has been previously partially received, and a transmitter of the PDU saves payload by not retransmitting the stale SDU. <P>COPYRIGHT: (C)2013,JPO&INPIT |
