receiving, from a base station of the wireless network, a first portion of system information, the first portion comprising an indication of a second portion of system information which is available upon request;
transmitting, to the base station, a first request requesting that the second portion of the system information be transmitted to the user equipment;
checking information received in subsequent transmissions of the first portion of the system information from the base station;
determining, based on the checking of the information received in the subsequent transmissions, whether an error has occurred in the first request for the second portion of the system information,
wherein the user equipment is operating in an idle state or an inactive state, and
wherein the error occurring in the first request for the second portion of the system information is determined when a broadcast flag is absent in the checked information;
determining that the requested second portion of the system information has not been received successfully by the user equipment based on the determined error;
transmitting, to the base station, a second request for the second portion of the system information based on the determination that the requested second portion is not successfully received in the idle state or the inactive state; and
switching from the idle state or the inactive state to a connected state of the terminal device based on a failure of reception of the requested second portion of the system information in response to the second request, wherein the switching is performed when the second request corresponds to a reached state of a maximum number of transmission attempts.
