Abstract
This disclosure relates to performing grouped MIMO communications in a cellular communication system. A cellular base station may select a precoding matrix for transmitting a downlink signal to a wireless device via a MIMO channel. The selected precoding matrix may have unequal weights for different MIMO subchannels. The downlink signal may be precoded using the selected precoding matrix. The precoded downlink signal may be transmitted to the wireless device via the MIMO channel. The wireless device may receive and decode the downlink signal.
