Abstract
A network node for handling a Multicast-Broadcast Single-Frequency Network (MBSFN) subframe configuration in a wireless communications network is provided. The MBSFN subframe configuration is configured for a first Radio Access technology (RAT) for operating in shared spectrum mode with a second RAT for radio communication with one or more User Equipments (UEs). The MBSFN subframe configuration is configured with a second RAT Cell-Specific Reference Signal (CRS) rate matching. For the MBSFN subframe configuration and for a number of past subframes, the network node obtains (401) a first requirement of subframes related to the first RAT. The first requirement is based on load and radio conditions related to the first RAT. For the MBSFN subframe configuration and for a number of past subframes, the network node obtains (402) a second requirement of subframes related to the second RAT. The second requirement is based on load and radio conditions related to the second RAT. The network node then decides (403) whether or not to change the MBSFN subframe configuration, based on the first requirement of subframes and the second requirement of subframes related to the second RAT. The econd …
