Methods for multiplexing scheduling request information and HARQ ACK/NACK information while transmitting and receiving PUCCH and apparatuses thereof

Abstract:

Disclosed is a method of multiplexing and transmitting/receiving scheduling request (SR) information and HARQ ACK/NACK information through short PUCCH (sPUCCH) consisting two or three symbols when an uplink control channel is transmitted. A method of a terminal transmitting the uplink control channel includes configuring i) first uplink control channel resources for indicating only the HARQ ACK/NACK information and ii) second uplink control channel resources for indicating both of SR information and the HARQ ACK/NACK information, setting the uplink control channel to include the SR information and the HARQ ACK/NACK information, and transmitting the uplink control channel, which consists of two or three symbols in one short transmission time interval (sTTI), to a base station.
