Abstract
There is provided a device and method for transmitting data with different QoSs in a mobile communication system. To transmit the data with different QoSs, an RLP layer divides the data into datagrams according to the QoSs, a MUX layer multiplexes the datagrams received from the RLP layer and outputs multiplexed TU data, a plurality of QCCHs for receiving the multiplexed TU data and outputs TU blocks with the QoSs by puncturing and repeating information added according to the QoSs for the multiplexed TU data, and an MQC maps the TU blocks received on the QCCHs according to the QoSs.

A protocol implementing device in a mobile communication system, compnsing:
- an RLP (Radio Link Protocol) layer for receiving data with different qualities of service (QoSs) and dividing the data into datagrams according to the QoSs;
- a MUX (Multiplexing) layer for multiplexing the datagrams received from the RLP layer and outputting multiplexed data in a transport unit (TU);
- a plurality of QCCHs (Quality Control Channels) for receiving the multiplexed TU data and outputting TU blocks with the QoSs by puncturing and repeating information added according to the QoSs for the multiplexed TU data;
- and
- an MQC (Multiple Quality Controller) for mapping the TU blocks received on the QCCHs according to the QoSs.
A method of transmitting data with different QoSs (Qualities of Service) in a mobile communication system, comprising the steps of:
- (1) receiving data with different QoSs and dividing the data into datagrams according to the QoSs in an RLP (Radio Link Protocol) layer;
- (2) multiplexing the datagrams received from the RLP layer and outputting multiplexed TU (Transport Unit) data in a MUX layer;
- (3) receiving the multiplexed TU data and outputting TU blocks with the QoSs by puncturing and repeating information added according to quality matcher (QM) values for the multiplexed TU data in a plurality of QCCHs (Quality Control Channels);
- and
- (4) mapping the TU blocks received on the QCCHs according to the QoSs in an MQC (Multiple Quality Controller).
