1. A communication method used for a terminal apparatus, the communication method comprising:
receiving, from a base station, a system information block (SIB) 1 (SIB1) via broadcast, the SIB1 including:
first information indicating one or more SIBs other than SIB1 provided in a first system information (SI) message and one or more SIBs other than SIB1 provided in a second SI message, the first SI message being different from the second SI message,
second information for determining a first plurality of scheduling times for receiving the first SI message and for determining a second plurality of scheduling times for receiving the second SI message, the first plurality of scheduling times being different from the second plurality of scheduling times, and
third information indicating that the first SI message is broadcast by the base station and the second SI message is not broadcast by the base station;
in a case that the UE requires system information included in the first SI message, receiving the first SI message based on the second information; and
in a case that the UE requires system information included in the second SI message:
transmitting an SI request through signaling to the base station, the signaling being transmitted to the based station on a dedicated resource configured by the base station,
calculating, based on the second information, the second plurality of scheduling times for receiving the second SI message, the second plurality of scheduling times comprising a current scheduling time and a set of subsequent scheduling times, and
performing the following actions iteratively within a threshold amount of time until the second SI message is received:
determining whether the second SI message is received within the current scheduling time, and
if the second SI message is not received within the current scheduling time, changing the current scheduling time to a subsequent scheduling time in the set of subsequent scheduling times.
