1. A method performed by a terminal, the method comprising:
receiving in a first cell, by a terminal from a base station, a system information, wherein the system information comprises at least a first uplink configuration;
determining, by the terminal, a presence of a second uplink configuration in the system information; and
performing in the first cell, by the terminal with the base station, a random access procedure based on a time alignment timer value in the first uplink configuration and a second Physical Uplink Control Channel (PUCCH) configuration in the second uplink configuration in case that the second uplink configuration is present in the system information,
wherein the first uplink configuration comprises the time alignment timer value and a first PUCCH configuration, and
wherein the second uplink configuration, which comprises the second PUCCH configuration, does not comprise the time alignment timer value.
