Abstract:
1. A window control and retransmission control method in which a radio link control (RLC) sublayer of a transmitting-side apparatus performs window control processing and retransmission control processing of a packet on the basis of positive/negative acknowledgement information (STATUS-PDU) received from a receiving-side apparatus, comprising steps of: managing, at the RLC sublayer of the transmitting-side apparatus, an acknowledgement information reception window; transmitting, from a medium access control (MAC) sublayer of the transmitting-side apparatus, to the RLC sublayer of the transmitting-side apparatus, an RLC-PDU including the STATUS-PDU received from the receiving-side apparatus, without performing a reordering processing for the RLC-PDU; and avoiding, at the RLC sublayer of the transmitting-side apparatus, an initiation of an RLC reset processing, by ignoring a sequence number of the RLC-PDU included in the STATUS-PDU received from the MAC sublayer of the transmitting-side apparatus, when the sequence number takes a value outside a range of the acknowledgement information reception window.
