Abstract: 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.

Abstract: There is provided a method including allocating, in dependence on interference information, at least one resource block group from a frequency carrier for use by one of a plurality of sets of user equipments, said frequency carrier including at least one first resource block group to be used for a first transmission mode and at least one second resource block group to be used for a second transmission mode.
