Abstract
Ways to mitigate problems caused by too narrow transmission zero (nulls) without significantly increasing computational complexity. For example, the problem can be mitigated by modifying MU-MIMO transmission schemes so that the nulls are widened. This way, the UEs that are to be protected from transmission interference stay within the nulls, despite the angular disturbances.
