Method for simultaneous transmission of control signals, terminal therefor, method for receiving control signal, and base station therefor

Abstract

The present invention relates to a method and an apparatus allowing a simultaneous transmission of control signals in a wireless communication system.

What is claimed is: 
     
         1 . A method for a user equipment to simultaneously transmit control signals, the method comprising:
 generating ACK/NACK information indicating whether downlink transmission is received; and   when a scheduling request and the ACK/NACK information are simultaneously transmitted, transmitting the ACK/NACK information through an uplink control channel resource for a first antenna using the first antenna, and transmitting the ACK/NACK information through an uplink control channel resource for a second antenna using the second antenna.   
     
     
         2 . The method as claimed in  claim 1 , wherein the uplink control channel resource for the first antenna and the uplink control channel resource for the second antenna correspond to resources configured for transmission of a scheduling request, or
 one of the uplink control channel resource for the first antenna and the uplink control channel resource for the second antenna corresponds to a resource configured for transmission of a scheduling request, and the other corresponds to a resource configured for transmission of an ACK/NACK.   
     
     
         3 . The method as claimed in  claim 1 , further comprising:
 receiving configuration information of the uplink control channel resource for the second antenna.   
     
     
         4 . The method as claimed  claim 1 , further comprising:
 determining the uplink control channel resource for the second antenna based on a resource where downlink control information is located or information included in the downlink control information.   
     
     
         5 . A user equipment, comprising:
 a control signal generating unit to generate ACK/NACK information indicating whether downlink transmission is received; and   a transceiving unit to transmit the ACK/NACK information through an uplink control channel resource for a first antenna using the first antenna and to transmit ACK/NACK information through an uplink control channel resource for a second antenna using the second antenna, when a scheduling request and the ACK/NACK information are simultaneously transmitted.   
     
     
         6 . The user equipment as claimed in  claim 5 , wherein the uplink control channel resource for the first antenna and the uplink control channel resource for the second antenna correspond to resources configured for transmission of a scheduling request, or
 one of the uplink control channel resource for the first antenna and the uplink control channel resource for the second antenna corresponds to a resource configured for transmission of a scheduling request and the other corresponds to a resource configured for ACK/NACK transmission.   
     
     
         7 . The user equipment as claimed in  claim 5 , wherein the transceiving unit receives configuration information of the uplink control channel resource for the second antenna. 
     
     
         8 . The user equipment as claimed in  claim 5 , wherein the transceiving unit determines the uplink control channel resource for the second antenna, based on a resource where downlink control information is located or information included in the downlink control information. 
     
     
         9 . A method for a base station to receive a control signal, the method comprising:
 receiving control information through an uplink control channel resource for a first antenna of a user equipment and an uplink control channel resource for a second antenna of the user equipment when the user equipment simultaneously transmits a scheduling request and ACK/NACK information indicating whether downlink transmission is received; and   decoding the control information.   
     
     
         10 . The method as claimed in  claim 9 , wherein the uplink control channel resource for the first antenna and the uplink control channel resource for the second antenna correspond to resources configured for transmission of a scheduling request; or
 one of the uplink control channel resource for the first antenna and the uplink control channel resource for the second antenna corresponds to a resource configured for transmission of a scheduling request, and the other corresponds to a resource configured for transmission of an ACK/NACK.   
     
     
         11 . The method as claimed in  claim 9 , further comprising:
 transmitting configuration information of the uplink control channel resource for the second antenna.   
     
     
         12 . The method as claimed in  claim 9 , further comprising:
 determining a resource where downlink control information is located or information included in the downlink control information, so as to indicate the uplink control channel resource for the second antenna.
