In dependence on interference information, one or more resource block groups are allocated from a frequency carrier for use by one set of plurality multiple sets of UEs. The frequency carrier includes one or more first resource block groups to be used for a beam forming mode and one or more second resource block groups to be used for a MIMO mode. This allocating can allow decreased interference between UEs using the beam forming mode and UEs using the MIMO mode. This may be applied to UEs having different DoA groups, so that different RBGs are assigned to different DoA beam forming groups to decrease interference with UEs in MIMO mode.
