Abstract

A wireless communication system providing wireless communication services and a terminal are provided. There is also provided a method for communicating data between a base station and a terminal in Evolved Universal Mobile Telecommunications System (E-UMTS) or Long Term Evolution (LTE) System evolved from UMTS, particularly, a method for transferring maximum data with minimum radio resources by controlling a Hybrid Automatic Repeat request (HARQ) operation in a dynamic radio resource allocation or scheduling.

Claims

1. A method of communicating data in a wireless communication system, the method comprising:

receiving a radio resource allocation message from a network, wherein the radio resource allocation message includes information related to a HARQ (Hybrid Automatic Repeat request) process; and

transmitting one or more data blocks according to the received radio resource allocation message.

2. The method of claim 1, wherein the radio resource allocation message is received on Physical Downlink Control Channel (PDCCH).

3. The method of claim 1, wherein the radio resource allocation message includes a plurality of HARQ process identifier information.

4. The method of claim 3, wherein the one or more data blocks are transmitted at each time indicated by the plurality of HARQ process identifier information.

5. The method of claim 1, wherein a pattern of the information related to HARQ process is predetermined during a call setup between a terminal and the network.

6. The method of claim 1, wherein the radio resource allocation message includes information related to a Transmission Time Interval (TTI).

7. The method of claim 1, wherein the radio resource allocation message includes a maximum number of retransmission in the HARQ process.

8. A mobile terminal for communicating data in a wireless communications system, the mobile terminal comprising:

a transceiver adapted to transmit or receive the data;

a memory adapted to store the data transmitted or received via the transceiver or from an external source; and

a processor cooperating with the transceiver and the memory and adapted to perform the steps of,

receiving a radio resource allocation message from a network, wherein the radio resource allocation message includes information related to a HARQ (Hybrid Automatic Repeat request) process; and

transmitting one or more data blocks according to the received radio resource allocation message.
