Using a control channel to indicate which subframes in a downlink channel contain system information

摘要

Disclosed is a network transmitter (110) for transmitting system information on a downlink shared channel in a wireless communication network. The network transmitter (110) is configured to transmit system information in recurring time windows, each of said time window spanning a number of subframes. The network transmitter (110) further comprises a baseband processor (130) configured to dynamically select which subframes within a given time window are to be used for carrying system information. The baseband processor (130) also includes an indicator in each of the selected subframes to indicate to receiving user equipment that the subframe carries system information.
