METHOD AND APPARATUS FOR ALLOCATING AND ACQUIRING ACK/NACK RESOURCES IN A MOBILE COMMUNICATION SYSTEM

摘要

A method and apparatus are provided for receiving ACK/NACK information by a base station. The method includes transmitting data and control information to at least one UE, the control information being transmitted on a downlink control channel including at least one CCE; transmitting information related to cyclic shift values of a sequence used for transmission of the ACK/NACK information in an RB, wherein the ACK/NACK information and CQI are multiplexed in the RB; checking a resource for reception of ACK/NACK information mapped to the at least one CCE based on the information related to cyclic shift values and a mapping rule between CCEs and a resource for reception of the ACK/NACK information, wherein the resource for reception of the ACK/NACK information is identified by a cyclic shift index, an orthogonal sequence index, and a resource block index; and receiving the ACK/NACK information for the transmitted data using the checked resource.

1. A method for receiving acknowledgement (ACK)/negative ACK (HACK) information by a base station in a mobile communication system, the method comprising:
transmitting data and control information to at least one user equipment (UE), the control information being transmitted on a downlink control channel including at least one control channel element (CCE); transmitting information related to cyclic shift values of a sequence used for transmission of the ACK/NACK information in a resource block (RB), wherein the ACK/NACK information and channel quality information (CQI) are multiplexed in the RB; checking a resource for reception of ACK/NACK information mapped to the at least one CCE based on the information related to cyclic shift values and a mapping rule between CCEs and a resource for reception of the ACK/NACK information, wherein the resource for reception of the ACK/NACK information is identified by a cyclic shift index, an orthogonal sequence index, and a resource block index; and receiving the ACK/NACK information for the transmitted data using the checked resource.
