초록 ▼

The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver orders the desired transmission units. The transmitter sends transmission units according to the order. Ordering and transmission are repeated until the quality measured by the receiver from each packet exceeds the predetermined quality value and the data which is to be transmitted and consists of packets is transmitted from the transmitter to the receiver. The invention also relates to a mobile communications system implementing the method of the invention.

대표청구항 ▼

[ What is claimed is:] [1.]1. A method for transmitting packet switched data in a mobile communications system between a transmitter-receiver pair using an ARQ protocol, which mobile communications system comprises a network part and at least one subscriber terminal and a bidirectional radio connection between the network part and the subscriber terminal, and the transmitter-receiver pair is formed by the network part and the subscriber terminal, the method comprising:inserting packet switched data to be transmitted on the bidirectional radio connection in transmission units:the receiver orders the first transmission of transmission units;the transmitter sends the transmission units according to the order of the first transmission;checking the quality of each received transmission unit indepently;the receiver orders the retransmission of those received transmission units that were not of a good enough quality;the transmitter sends the transmission units according to the retransmission order;retransmission-ordering and retransmission are repeated until the quality measured by the receiver from each packet exceeds the predetermined quality level and the data which is to be transmitted and consists of packets is transmitted from the transmitter to the receiver.
