Abstract
The present invention relates to a resource allocation device for minimizing delay of an uplink retransmission resource allocation process in a wireless communication system having a high data rate, and a method thereof. In the method, user data are received and an ACK/NACK state of the received data is determined, and when the NACK state of the received data is determined, retransmission resource allocation is requested, retransmission resources are allocated, and retransmission resource allocation information is generated to be transmitted.
Claims11
A method for allocating resources in a wireless communication system, the method comprising:
- determining an ACK/NACK state of received data;
- allocating resources for retransmission when the received data are in the NACK state;
- and
- transmitting information for allocating the retransmission resources,
- wherein, in the allocating of the resources, the retransmission resources are allocated at a time allowed by a system without a resource allocation request for the retransmission from a wireless terminal.
A resource allocation device in a wireless communication system, the device comprising:
- a receiving unit for receiving user data and determining an ACK/NACK state of the received data;
- a controller for determining a NACK state of the received data and requesting retransmission resource allocation;
- a resource allocation unit for allocating retransmission resources according to a request from the controller, and generating retransmission resource allocation information;
- and
- a transmitting unit for transmitting the retransmission resource allocation information of the resource allocation unit,
- wherein, in the allocating of the resources, the retransmission resources are allocated at a time allowed by a system without a resource allocation request for the retransmission from a wireless terminal.
