1. A method of receiving updated system information in a wireless communication system, the method comprising:
- receiving system information comprising a value;
receiving, by a terminal via a downlink shared control channel, a notification for changing of the system information, wherein the notification is one of a plurality of notifications that are each received during one of a plurality of modification periods, wherein each period of the plurality of modification periods has boundaries which are defined based on a System Frame Number (SFN) and the value of the system information;
determining, for each of the plurality of modification periods, if there is a change in the system information based on the received notification;
if there is a change in the system information, then receiving, by the terminal, an updated system information during a modification period of the plurality of modification periods, wherein the updated system information is received via a downlink shared data channel;
wherein changes of the system information only occur at respective modification periods of the plurality of modification periods.

14. A method of transmitting updated system information in a wireless communication system, the method comprising:
-
transmitting, by a network, system information comprising a value; transmitting, by the network via a downlink shared control channel, a notification for changing of the system information, wherein the notification is one of a plurality of notifications that are each transmitted during one of a plurality of modification periods, wherein each period of the plurality of modification periods has boundaries which are defined based on a System Frame Number (SFN) and the value of the system information; transmitting by the network, when there is a change in the system information, an updated system information during a modification period of the plurality of modification periods, wherein the updated system information is transmitted via a downlink shared data channel; wherein the transmitting of the updated system information occurs a number of times with the same content within the modification period; and wherein changes of the system information only occur at respective modification periods of the plurality of modification periods. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
