Title: CONFIGURING NON-MBMS (MULTIMEDIA BROADCAST MULTICAST SERVICES) SUBFRAMES FOR ADDITIONAL SYSTEM INFORMATION
Abstract:
When a Wireless Device (WD) is in broadcasting range of an access node in a Multimedia Broadcast Single Frequency network (MBSFN), in certain network configuration the access node needs to send additional system information (SI). According to embodiments herein, the access node broadcasts towards the WD a subframe configuration for the network, the subframe configuration indicating additional non-MBMS subframes that include system information (SI) are to be expected. This allows the WD to be informed it will receive additional SI in the yet-to-come non-MBMS subframes. When the WD then receives a subframe, it determines, using the received subframe configuration, that the subframe is a non-MBMS subframe; and obtains the additional SI from the received subframe. This allows for extra SI to be sent flexibly to the WD, when needed, while preventing the loss of additional bandwidth dedicated to the extra SI when this extra SI is not needed.
