ABSTRACT:
Subchannel allocation apparatus for allocating subchannels of a MIMO radio channel to a plurality of users, the MIMO radio channel having a first number of subchannels, each subchannel having a transmission capacity. The subchannel allocation apparatus includes a subspace determiner for determining a subspace of the MIMO radio channel, the subspace having a second number of subchannels, the second number being lower than the first number and each subchannel of the second number of subchannels having a higher transmission capacity than the subchannel with the lowest transmission capacity of the first number of subchannels. The subchannel allocation apparatus further includes a subchannel allocator responsive to the subspace determiner for allocating a subchannel from the second number of subchannels of the subspace to a user based on an allocation metric.
