1. A method implemented by a device at a base station of a cell of a cellular network, comprising:
broadcasting, to at least one terminal, essential system information, the essential system information comprising a resource configuration of a demand channel for requesting optional system information to be provided to the at least one terminal on a demand-basis and information identifying a predefined resource zone for receiving the optional system information in response to a request for the optional system information, wherein the essential system information is required to access a cell of the device, wherein the demand channel is a channel on which user equipments send a request for requesting at least a part of the optional system information on the demand-basis to avoid periodic transmission of the optional system information, wherein the information identifying the predefined resource zone comprises at least one of a time resource or a frequency resource [ an identifier of one or more physical resource blocks (PRBs) ] for receiving the optional system information [ , and wherein the resource configuration of the demand channel includes at least one of the following: a period of the demand channel, a time offset with respect to a reference signal, or a frequency offset with respect to the reference signal] ;
while monitoring the demand channel, receiving a request from the at least one terminal for at least a part of optional system information other than the essential system information; and
in response to receiving the request from a user equipment, broadcasting an indicator in the predefined resource zone to indicate existence of the part of the optional system information and broadcasting, on the demand basis, the part of the optional system information in the predefined resource zone.
