Method and apparatus for allocating ACKCH resources in a wireless communication system

摘要

A method for allocating physical resources to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) signal channel representative of a response signal in a wireless communication system. The method includes grouping ACK/NACK signal channels corresponding to a plurality of resource blocks used for transmission of a data channel or a control channel into a plurality of groups so ACK/NACK signal channels having consecutive indexes do not belong to the same group; and allocating same frequency resources to ACK/NACK signal channels belonging to the same ACK/NACK signal channel group and allocating orthogonal sequences so ACK/NACK signal channels in each ACK/NACK signal channel group are distinguished in a code domain.

1. A method for allocating physical resources to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) signal channel in a wireless communication system, the method comprising:
grouping ACK/NACK signal channels into a plurality of groups based on uplink resource block indexes so that ACK/NACK signal channels of consecutive uplink resource blocks do not belong to the same group, wherein each ACK/NACK signal channel is used to transmit a downlink ACK/NACK signal in response to a data channel received through a respective one of a plurality of uplink resource blocks; and allocating same frequency resources to ACK/NACK signal channels belonging to the same ACK/NACK signal channel group and allocating orthogonal sequences so ACK/NACK signal channels in each ACK/NACK signal channel group are distinguished in a code domain.
