Abstract:
Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.
