摘要：
Disclosed is a method for a base station to transmit a discovery reference signal (DRS) through a channel of an unlicensed band. The base station attempts a first access to the channel of the unlicensed band so as to transmit a first DRS in a first DRS measurement timing configuration (DMTC) period. When the first access fails, the base station attempts a second access to the channel of the unlicensed band with a shorter predetermined period than the first DMTC period so as to transmit a second DRS in the first DMTC period.
