Method and apparatus for transmitting and receiving packet data between a node b and a ue using harq in a mobile communication system

A method of transmitting packet data by a User Equipment (UE) using a Hybrid Auto Repeat Request (HARQ) scheme in a mobile communication system, the method comprising the steps of:

• receiving connection setup information from an Enhanced Node B (ENB), the connection setup information including a first Maximum Retransmission Limit (MRL) value to be applied to quasi-real time data;
• when data to be transmitted is the quasi-real time data, transmitting a resource request to the ENB, the resource request including information indicating that the UE transmits the quasi-real time data;
• receiving a transmission resource that is allocated from the ENB in response to the resource request;
• and
• transmitting the quasi-real time data to the ENB by using the allocated transmission resource and applying the first MRL value the quasi-real time data.

A method of receiving packet data by an Enhanced Node B (ENB) using a Hybrid Auto Repeat Request (HARQ) scheme in a mobile communication system, the method comprising the steps of:

• transmitting connection setup information to a User Equipment (UE), the connection setup information including a first Maximum Retransmission Limit (MRL) value to be applied to quasi-real time data;
• when a resource request is received from the UE, the resource request including information indicating that the UE transmits the quasi-real time data, allocating a transmission resource to the UE in response to the resource request;
• and
• receiving the quasi-real time data, which the UE transmits using the allocated transmission resource, by applying the first MRL value the quasi-real time data.

An apparatus for transmitting data by a User Equipment (UE) using a Hybrid Auto Repeat Request (HARQ) scheme in a mobile communication system, the apparatus comprising:

• an HARQ processor for performing a HARQ operation;
• a transceiver for receiving a packet subjected to the HARQ operation from the HARQ processor, transmitting the packet to an ENB, and receiving configuration information from the ENB, the configuration information including Acknowledgement/Negative Acknowledgement (ACK/NACK) information for the transmitted packet and a first Maximum Retransmission Limit (MRL) value to be applied to data that is transmitted over a persistent resource;
• and
• a controller for controlling the HARQ processor to apply the first MRL value to quasi-real time data and controlling the quasi-real time data to use the persistent resource when data to be transmitted by the UE is the quasi-real time data.
