Method for receiving ACK/NACK signal in mobile communication system

摘要

A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals ina mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.

1. A method of transmitting ACK/NACK information for downlink data at a mobile communication apparatus, the method comprising:
receiving control information for notifying resource position for the downlink data via one or more control channel elements (CCEs); receiving the downlink data; and transmitting the ACK/NACK information for the downlink data, wherein a resource index for the ACK/NACK information is determined using the following expression: α′+β*ICCE, where α′ is a value including 0, β is a value other that 0, and ICCE is an index of a CCE of the one or more CCEs.
