The communication method of a terminal includes: receiving a message containing information regarding a semi-persistent scheduling (SRS) configuration from a base station; determining whether a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and when: a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and the terminal does not have data to be first transmitted via the sub-frame configured with an uplink grant according to the SPS configuration, performing the non-adaptive re-transmission. ## Claims ### Claim 1 A method performed by a terminal in a wireless communication system, the method comprising: transmitting, to a base station, a request message associated with a radio resource control (RRC) connection;
