Apparatus and method for transmitting and receiving packets in a mobile communication system supporting hybrid automatic repeat request
First Claim
1. A method for operating Hybrid Automatic Repeat reQuest (HARQ) in a mobile communication system, the method comprising:
- receiving a number of HARQ processes of a persistent resource allocation and persistent resource allocation interval information for a first transmission;
receiving data in the first transmission at a subframe based on the persistent resource allocation interval information;
calculating a HARQ process IDentifier (ID) using the number of HARQ processes of the persistent resource allocation, the persistent resource allocation interval information, and time information;
receiving control information including the HARQ process ID on an L1 control channel;
receiving data in a retransmission based on the control information including the HARQ process ID;
combining the data received in the first transmission and the data received in the retransmission; and
decoding the combined data.

Abstract
An apparatus and a method are provided for receiving data in a communication system. Information is received representative of a number of processes of a persistent resource allocation and a persistent resource allocation interval. Data is received in a new transmission based on the received information. A HARQ process ID is calculated using the number of processes of the persistent resource allocation, the persistent resource allocation interval, and time information. Control information including the HARQ process ID is received. Data is received in a retransmission, based on the control information including the HARQ process ID. The data received in the new transmission and the data received in the retransmission are combined. The combined data is decoded.
