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 for receiving the optional system information;
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.

Abstract
Embodiments of the present disclosure relate to methods and devices for broadcasting system information on demand. In example embodiments, the system information is classified as essential and optional system information. The essential information is broadcasted periodically, and the optional system information is broadcasted in response to the request by UEs. In this way, the system information can be in an effective and efficient way, thereby saving significant resource and energy can be saved especially in the case of no load or low load.

10. A device at a base station of a cell of a cellular network, comprising:
-
a transceiver configured to broadcast, 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 terminals 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 for receiving the optional system information; and a controller configured to, while monitoring demand channel, receive a request from the at least one terminal for at least a part of optional system information other than the essential system information, the transceiver being further configured to; broadcast an indicator in the predefined resource zone to indicate existence of the part of the optimal system information; and in response to receiving the request and on the demand-basis, broadcast the part of the optional system information in the predefined resource zone. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
