DATA COMMUNICATION METHOD, COMMUNICATION SYSTEM AND MOBILE TERMINAL

摘要

In an LTE communication system including a base station (2) and a mobile terminal (3) that perform data transmissions therebetween by use of OFDM (Orthogonal Frequency Division Multiplexing) as a downlink access mode, if an S-RACH is to be used to transmit an uplink scheduling request signal (SR) during a transmission of ACK/NACK signals using an ACK/NACK dedicated channel, then the transmission of ACK/NACK signals is halted while the uplink scheduling request signal (SR) is being transmitted.
