Title: Appratus and method for transmitting/receiving uplink control channels in wireless communication systems
Inventor: CHO JOON YOUNG
IPC: H04L27/26
Filed: 2007-07-13
Abstract: An apparatus for transceiving an uplink control channel in a wireless communication system and a method thereof are provided to prevent a CQI channel which a terminal transmits from being recognized as ACK or NACK information, when a downlink scheduling control channel for the terminal fails to be received. A CQI generator(601) and an ACK/NACK generator(603) produce CQI and ACK/NACK information. A channel coder(605) channel-codes a CQI value in case of transmitting only the CQI. On the other hand, in case CQI and ACK/NACK are transmitted at the same time, a multiplexer multiplexes the CQI and ACK/NACK and then and coder(607) channel-codes the multiplexed result. The first switch(609) switches the output of one of the channel coder, multiplexer and coder to the second switch(615) according to the control of the controller. Depending on whether the terminal transmits only the CQI or the CQI together with the ACK/NACK, the controller transmits control information of a pattern to an RS symbol generator(613) so as to generate an RS.
