METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA

Title:

METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA

Document Type and Number:

WIPO Patent Application WO2003077463

Kind Code:

A3

Abstract:

Each frame (500) being transmitted and received contains two frame sequence numbers. The first frame sequence number (501) comprises the sequence number of the frame being transmitted, while the second frame sequence number (502) comprises the sequence number of the next expected frame being received by the transmitter. Because each frame (500) contains a sequence number for the next expected data frame (502), transmitting circuitry (301, 302) will more quickly realize if a particular frame has not been received by the receiver. This reduces the number of idle frames needed to be transmitted at the end of the data session.
